HYDROTEX linings and mats and HYDROCASTTM Armor Units are installed by positioning fabric forms over the areas to be protected and then pumping high-strength,fine aggregate concrete (structural grout) into the forms. The fabric forms can be placed and filled either underwater or in-the-dry. The high-strength, fine aggre- gate concrete is used in place of conventional concrete because of its pumpability,high-strength,impermeability,and absorption resistance. HYDROTEX linings and mats and HYDROCASTArmor Units are used to protect canals, channels, culverts, dams, dikes, embankments, bridge piers,spillways,underwater pipelines,and other hydraulic and marine structures from the forces of flowing water and wave action. HYDROTEX Linings and Mats are also used to protect geomembranes and geosynthetic-clay liners from mechanical damage in landfills,res- ervoirs, sewage lagoons, ash pits, cooling ponds, and other contain- ment, capping and environmental applications. In addition to significant performance advantages, HYDROTEX fab- ric-formed concrete is economical to install. It eliminates the need for heavy equipment, steel reinforcement, and forming and stripping of conventional concrete forms. It generally does not require specialized labor or dewatering of the job site prior to installation. This manual is designed as a guideline for the construction and qual- ity control for HYDROTEX fabric-formed concrete systems. Prior to the delivery of materials to the job site, its contents should be thor- oughly reviewed by those given the responsibility for design, installa- tion and inspection. The contents of this manual are only general guidelines and do not relieve the contractor of the responsibility to adhere to the Contract Drawings and Specifications. It is recommended that the Engineer of Record review these guidelines and specify any additional, project-specific installation procedures he considers necessary. Page 2 General Characteristics of Fabric Forms for HYDROTEX Linings and Mats and HYDROCAST Armor Units HYDROTEX fabric forms are constructed of high-strength, syn- thetic yarns formed into woven,double-layer fabrics.Textured yarns comprise a minimum of 50%of the fabric weight for improved ad- hesion to fine aggregate concrete and better filtration characteris- tics.The yarns are woven into a network such that the yarns retain their dimensional stability relative to each other, including at the fabric selvages(edges).The selvage edges of the top and bottom layers of fabric are reinforced for a width of 1.35 inches(35 mm) by adding at least 6 warp yarns to the selvage construction. The reinforced selvage edges provide superior strength to sewn seams used in the fabrication of fabric forms. The fabric forms are designed to serve as filters as well as con- crete forms with a permeability selected to permit expulsion of ex- cess concrete mixing water while retaining the cement solids.The fabric forms are resistant to alkalis, acids, organic solvents, and biological organisms. After the fabric forms are woven and inspected, mill width rolls of fabric are factory assembled either into panels designed to fit project dimensions and topography or into forms of specified dimensions. The designs of the fabric forms and their woven construction pro- vide HYDROTEX fabric forms with a range of important benefits including: High Strength,enabling the fabric forms to perform effectively under concrete pumping pressure; High Elongation, to resist tear and puncture failure and to reduce form contraction; Excellent permeability,to expel excess mixing water; Lightweight,for ease of installation; and Uniformity in dimensions,to assure consistent performance characteristics. The fabric forms are designed to adhere to the fine aggregate con- crete fill.Though it is assumed that the top layer of the fabric form may eventually be lost to abrasion and ultraviolet degradation,the bottom layer is expected to last indefinitely and to provide a low modulus tensile reinforcement. There are two primary types of HYDROTEX fabric-formed con- crete systems - HYDROTEX Linings and Mats and HYDRO- CAST Armor Units.

Admixtures Pozzolan grade fly ash may be substituted for up to 35% of the ce- ment as an aid to pumpability.(The pumpability of fine aggregate con- crete mixes containing course sand is improved by the addition of fly ash.) Grout fluidifier, water reducing or set time controlling agents may be used as recommended by their manufacturers to improve the pumpability and set time of the fine aggregate concrete. Ready-mix Fine aggregate concrete should be pre-mixed at a concrete batch plant and delivered by ready-mix trucks to the job site. /fa continuous supply of concrete can not be assured a reserve of concrete should be maintained in a holding hopper equipped with an agitator The consistency of the fine aggregate concrete delivered to the job site should be maintained in the 9-11 second range when passed through the 0.75 inch(19 mm)orifice of the standard flow cone that is described in ASTM D 6449 (Fig. 1). Tests utilizing a concrete slump cone are not appropriate. Table 1.0 Typical Range of Mix Proportions Mix Proportions After Placement -.

Geotextile Filter Fabric (Geotextiles) Filter Fabric Geotextile filter fabric is often used under fabric-formed con- crete linings and mats and concrete armor units (Fig. 3).

When installing fabric form linings, mats and armor -— units on silts, sandy silts or fine sand, the specifica- • _ tions may call for the addition of a sublayer. The 'T \_ = sublayer serves to prevent serious downslope migra- _ ' tion of the subsoil particles. Sublayers should be con- structed of granular material. 't1.

Table 5.0 provides property re- quirements for the fabric used in form construction. Filter Point (FP) Linings -- Filter Point Linings (Fig. 7)with filtering points (drains) provide ero- sion resistant, permeable concrete linings for ditches, channels, ca- nals,streams,rivers,ponds,lakes,reservoirs,marinas,and protected 411 port and harbor areas. Filter Point Linings have a cobbled surface and a relatively high coefficient of hydraulic friction in order to achieve , lower flow velocities and to reduce wave run-up.The filter points pro vide for the relief of hydrostatic uplift pressures,increasing the system's stability. Filter Point Linings were the first type of fabric form for concrete de- veloped. In 1965,a Dutch patent was issued for"fabric-formed slope paving."The form suggested by this patent was later refined to create Figure 8 the first"filter point"lining.

The interweaving of the two layers results in an area of .� r,• , double density, higher strength, single layer fabric. The weave of ' � a* ` • the fabric at the center of these drain locations incorporates a • „ •4`..;-; `Twill Weave"in order to "open up the fabric'and permit the flow of ground water through the drain while retaining sod particles.A { t twill is a weave characterized by diagonally-oriented yams .,!'"'r • am ;� woven over then under more than one yarn. Figure 9 illustrates the construction of a filter point with a twill weave center designed to function as a drain as we//as a filter The cross shaped design reduces applied stress to the filter point during concrete pumping. Filter bands are also constructed with a twill weave center Figure 9 Page 8 Uniform Section (US) Linings Uniform Section Linings (Fig. 10) are similar to traditional concrete slope paving. They create a solid, high quality concrete lining with a relatively low hydraulic resistance and uniform cross section. These 11414411440.. linings are used to reduce the infiltration or exfiltration of aggressive ,,,►, waste and chemical fluids into or out of open channels and basins. They are also used to reduce exfiltration in arid regions where open ` channels and basins require watertight linings. Uniform Section Linings are resistant to leachate and most chemi- i cals. They protect geosynthetic liners from mechanical damage, ex- posure to UV light, and freeze-thaw cycles. These self-supporting, high strength linings permit construction on steep side slopes and Figure 10 replace the conventional use of clay or sand as liner protection.Place- ment of the forms and concrete filling can be performed without the use of equipment on the liner. The tensile strength and abrasion re- sistance of the fabric protect the liner from the pumped concrete. Alp' Enviromat'' (EL and EB) Linings - Enviromat Linings EL(Fig. 11)and EB (Fig. 12)are installed to pro- , vide protection against periodic high flows.After installation, vegeta- -,1"-" e < tion can be planted within the open structure of the lining to create a more natural appearance. Enviromat Linings are used in drainage .14•;a' ditches and on the upper slopes of channels, canals, lakes, reser- ' voirs, rivers, and other water courses as well as for embankments subject to heavy run-off. Enviromat Linings are comprised of concrete-filled elements and un- Figure 11 filled areas that allow for the establishment of vegetation. Once the concrete sets, the defined unfilled and interwoven areas are opened by cutting the fabric and are planted or are filled with topsoil and seeded.Within a growing season a vegetated cover will normally ex- tend over the lining, resulting in an erosion control system with the Ili hydraulic,ecological and aesthetic features desired. EL linings have a greater open area (-35%)than EB (-20%), so a vegetated cover ♦ 11110, ,gym►. '� will be established more rapidly. However,EB linings are designed to ., ►'^� Z4416' 1 articulate and are more tolerant of uneven settlement after installa- O l_ , Articulating Block (AB) Mats 1 Articulating Block Mats (Fig. 13)form cable-reinforced concrete block mattresses that resist erosive forces. They are often constructed where a revetment is exposed to frontal attack by wave action.AB Mats are Figure 12 typically used to protect coastlines, canals, rivers, lakes, reservoirs, underwater pipelines, bridge piers, and other marine structures from propeller wash, ship wakes, wind waves, currents, and high velocity flows. They are also used in environmental construction for landfill .41,4,44e- ,_,,,, caps, down chutes, and collector channels. 3, The AB fabric form consists of a series of compartments linked by an 111411111: ',� interwoven perimeter.Grout ducts interconnect the compartments,and high strength revetment cables are installed between and through the compartments and grout ducts. Once filled, the AB Mats become a mattress of pillow-shaped, rectangular concrete blocks.The interwo- ven perimeters between the blocks serve as hinges to permit articula- tion. The cables remain embedded in the concrete blocks to link the blocks together and facilitate articulation.

Page 10 Physical Requirements:At the time of del/very to the job site, the fabric used in form construction should conform to the minimum property require- ments of Table 50.All fabric forms should be free of rips or defects that would interfere with the proper placing of the fabric forms or significantly impair the strength or performance of the construction. Minor holes incidental to the usual method of manufacture or minor rips resulting from shipment and delivery or handling are not grounds for rejection. Small rips or holes are repaired by the contractor in the field by sewing.

Upon the project engineer's approval of the submittal pack- age Synthetex manufacturing department commences panel r1' fabrication and confirms the delivery schedule. � Proper Storage and - , Handling of Fabric Forms Fabric forms are delivered at the job site in trailers or ocean Figure 17 containers. Fabric forms are stacked in a manner that as- sures ease of unloading. Standard 40 ft(12 m) long trailers or containers hold up to 215,000 ft2(20,000 m2)of fabric forms per load.Fabric forms are normally delivered to the site pack- aged in accordance with Table 6.0. Rolls and panels of fabric forms are each wrapped in two layers of protective cover:the first layer(inner layer)is a wa- terproof, opaque, plastic cover the second (outer layer)is a woven, abrasion resistant,fabric cover(Fig. 17). When fabric forms are to be inventoried at the job site, they should be kept dry and remain wrapped so that they are pro- tected from the elements during storage and handling.If stored outdoors, they should be elevated and protected with a wa- terproof cover that is opaque to ultraviolet light.Care should be taken not to damage the fabric forms during unloading, storage and handling. Note: The contractor should unload the fabric forms by hand or with a forklift or similar equipment. When lifting rolls or panels of fabric forms make sure that workers have proper back support.

The r tubes have a flange at one end and a point at the other end of a 0.75 s ;- inch (19 mm)diameter barrel. The pointed end has four small holes that allow the passage of water but retain large soil particles. There is t;" - a flanged cap that is placed over the pointed end and locks in place. Weep tubes are available in lengths of 3, 4, 6, 8, and 10 inches (76, 102, 152,203,and 254 mm)when measured between the assembled `tr ,4•weep tubes flanges. The location of weep tubes,if required,are clearly marked on the fabric form panel shop drawings. s N Weep tubes are assembled by forcing the pointed end of the weep tube through both the top and bottom layers of the fabric form and locking the flanged cap over the pointed end(Fig.23). A small square - of filter fabric can be placed over the in-place flanged cap and se- cured with a fastener(Fig.24)or the fabric form can be placed over a continuous layer of filter fabric as shown in Figure 23. In either case i >' the filter fabric should prevent fine soil particles from passing through Figure 22 the weep tube. High-Strength Cable (for Articulating Block Mats) • High-strength cables should be constructed of high tenacity,low elon- ` gation, continuous filament polyester fibers. High-strength cables ' should have a core construction comprised of parallel fibers contained • within an outer jacket or cover. The weight of the parallel fiber core _ , should be 65 to 75 percent of the total weight of the cable.High-strength cables are available in a range of diameters and strengths(Table 8.0). Table 9.0 provides the suggested high-strength polyester cable diam- eter for the range of Articulating Block Fabric Forms placed on slopes of different lengths.

The first fabric form panel should be carefully placed Figure 33 at the designated starting point and rolled out into position (Fig. 33). Page 21 The panel should be extended into position by pull- ing the leading side of the panel in the direction of the concrete lining or mat placement(Fig.34).Spe- 00 < cial care should be taken to assure that the sides and the ends of the panel are exactly parallel to their respective alignment lines. • f _ 4 . :. • 1 ;4 11 IQ xl. 5 t~ o r �� Figure 34 Fabric form panels should be placed loosely, but without folds, to allow for proper filling with fine ag- >- gregate concrete.The extra fabric form provided for form contraction should be gathered into temporary e _ _ tucks at the top of the slope and at each seam(Figs. ,• 35 and 36). Panels that are stretched or taut will not --�-W-�-*^. permit the required fabric contraction,therefore the {`- �' " fabric forms will not fill to their required thickness. ' For example, an 11 mill-width-wide panel of Filter a � Point fabric form will be 66 feet(20 m)wide. When . filled with fine aggregate concrete the width will con- g t ' "°" tract to a finished width of 60 feet(18 m).See Table 7 for the contraction factors of the various form styles. E The fabric form in this example should therefore be Iil placed with the seams (which join mill widths) 5.5 [ feet(1.6 m)apart.

However, panel alignment is impor- tant in providing a uniform and attractive ap- pearance in the finished installation. Fabric form placement should proceed concrete fill- ing -' by no more than the distance that can be coin- pleted in one day. If the panels are to be placed underwater or if the .,.►' ' aesthetic appearance is not of importance,the time involved in inverting the panels as described above may not be justified.Adjacent panels may be joined by abutting the panels and sewing the bottom and then the top seam. Except for the small tab of fabric Figure 41 that will protrude above the surface of the concrete lining or mat, seaming the fabric in this manner is functional and will not adversely effect the perfor- mance of the installation. Sewn seams should be made using portable, hand- held,sewing machines and nylon or polyester sew- ing thread. Generally, a prayer seam with a U.S. Federal Standard Type 101 stitch is the most suit- able. It is strongly recommended that each seam be s29'7104,, made with two parallel passes of the sewing ma- eef(is,afhs•s chine to assure a tight seam equivalent to those ereslfeet(fs S seams sewn in the factory.

Page 24 Placement of fabric form panels around curves and turns Curves or turns may be accomplished by panels with or more angled mill widths. Panels with angled , one mill widths should be carefully prefabricated or field assembled by cutting and sewing the mill widths of the fabric form(s) to obtain true angles and edges 3 (Fig. 42). Curves and turns in the project can also be accom- plished by positioning the sides of alternate panels perpendicular to the concrete lining or mat's longitu- dinal alignment line.The alternate panels should then be pumped to form standard rectangular shaped sec- tions. The intermediate panels should then be pumped. These intermediate panels will form sec- tions with a slightly trapezoidal shape to complete Panels 1 and 3 are filled before panel 2.

The excess width of fabric form, between seams,is carefully accumulated into pleats that taper the mill width down toward the smaller ra- dius(Fig.44). Placement of fabric form panels into trenches After the fabric form panels have been positioned, Cord Point the designated sides of the panels should be folded into the anchor trench,flank trenches and toe trench.

The divers can prepare the fin- ished grading, inspect the area to be protected,and position and secure the filter fabric and fabric forms. The securing of the fabric may require sand bags or weights, or lines tied from shore to hold the fabric in i i position. i A small quantity of bulk(uncut and unassembled) .r 4k fabric form should be ordered for each project. This fabric can be used for special field tailoring around drains,headwalls and field changes requiring exten- sions to pre-assembled panels.

In all cases the lap must be shingled to correspond with the direction of flow. Page 29 A lap joint may be desirable along the centerline of a wide channel or a channel with changes in bottom width or slope length. It may allow the contractor the flexibility to use a standard pane/size to conform to the van.- able design cross sections. A lap joint may be constructed by overlapping adjacent fabric form panels by a minimum of 3 feet(1 m). Butt joints are not permitted. The proper method for constructing a lap joint is the following pumping sequence(Fig. 52): •Fill the next to the last mill width of the upstream Fill First Fill Third Fill Second form,leaving the last section of the upstream Baffle Flow and preceding panel unpumped. •Excavate a terminal trench as described in Fig- ure 52 or in the Contract Drawings. _ • Position the side of the succeeding panel ap- Baokfiu proximately 3 feet(1 m)from the last pumped 2 ft(60 cm)min • mill width of the preceding panel. ` I{ r , ' Panel Thickness •Pump fine aggregate concrete into the first mill width of the succeeding panel. . 3 ft(90 cm)min • Backfill the terminal trench so that the last mill width of the preceding panel can be laid to 1 ft(30 cm)min form an even transition to the succeeding panel. Figure 52 • Extend the last mill width of the preceding panel over the indented portion of the first mill width of the succeeding panel and fill this section. Pipes, piles, culverts, trees and other appurtenances Fabric forms should be tailored in the field to fit around pipes, piles, cul- verts,trees and other appurtenances.An opening should be cut in the fab- ric form that is slightly smaller than the object and the perimeter of the • opening is sewn closed. When the fabric form panel is placed the tailored opening is either slid over or wrapped around the object.As fine aggregate It 4k., ,. concrete is pumped into the section of the panel with the tailored opening it will form snugly around the object(Fig. 53). r s- An alternate method of construction is to first fill the fabric forms that have been placed in dose proximity to the object and then to place a separate collar, snugly around the object, overlapping the primary concrete fining or mat by a minimum oft ft(60 cm)(Fig. 54). Backfilling and compaction of trenches The backfilling and compaction of anchor,flank and toe trenches and other open excavations should proceed in not less than one hour behind the concrete filling of the fabric formed linings or mats.Anchor and flank trenches should be backfilled and compacted to the top of the concrete linings or mats.Toe trenches should be backfilled as shown on the Construction Draw- ings. The trenches of completed sections of concrete linings or mats should �' be backfilled and compacted by the end of the workday ; - Foot traffic + Foot traffic on the freshly pumped fine aggregate concrete lining or mat should be avoided for a period of not less than one hour after concrete .� injection or until the concrete is resistant to indentation. Should traffic be '` unavoidable, the contractor should place board walks along the finished 1116 mt. filled concrete areas.This will reduce the amount of objectionable indenta- tion. Footprints will leave permanent impressions in the installed fabric- Figure 53 formed concrete linings or mats. Cleanup Any fine aggregate concrete that may spill on top of the fabric formed con- crete lining or mat should be picked up by hand or trowel and the surface Page 30 , , y , smoothed by cloth or broom. Such unnecessary spillage of con �.-, y _y y -, r `y + `, crete will cause an unsightly appearance and may clog the con- -,- -, ,- ` r - crete lining or mat's drainage areas such as filter points, filter ` -; 4- ` bands or the permeable interwoven perimeter areas of the fabric -1'-. _, - forms. The insta/lationcrew should be instructed tocarefully kink" ' - " the concrete pump hose when it is moved from one injection point ` y y�` ,- to another or to p/ace the end of the concrete injection pipe in a y -,- , pail when moving the concrete pump hose. r y ,- y The freshly pumped fabric formed concrete linings and mats ' ` , y, r ` . should never be washed (sprayed) under pressure with wa- -. '" y y -. ` , ter in an effort to clean or remove spills from its surface.A ` ,- ` " - , - , wet cloth should be used for clean up and spill removal. Figure 54 The cement film that bleeds through the top layer of the fabric forms provides a bond between the fabric form and the concrete fill and a degree of protection against ultraviolet degradation of the fabric. Should this film be removed by washing the uncured concrete linings or mats, cement may be also washed out from beneath the top layer of fabric.The result would be a loss of con- crete-to-fabric bond, a sandy, low strength outer surface of con- crete and a concrete lining or mat which will exhibit low abrasion Geotextile Filter resistance and durability.

The diameter of the anchor rods is selected to provide Steel Anchor Rod the supplemental shear strength required for the installed area of (threaded) PP 9 Nut lining or mat. The threaded anchor rods should be grades 40 or 50 and a 6 inch (152 mm) square washer and nut are placed at o 1 o I the end of each anchor. Typically, the total length of the anchor rod is the sum of the embedment depth,the average thickness of Washer the lining or mat, plus 6 inches(152 mm).The embedment depth of the anchor rod must be sufficient to resist the pullout force applied in line with the rod. The depth is dependent upon the concrete used in the anchor block and the type of soil. For most 0 0 0 conditions, an embedment depth of 24 inches(610 mm)is suff- cient Anchor rods are installed by excavating a 6 inch(152 mm)diam- eter anchor hole with a post digger or auger, filling the hole with concrete, and inserting the anchor rod. Once the concrete has O° 0 O° set,a geotextile filter fabric and the fabric form are placed and the anchor rod is forced through the filter fabric and both layers of the fabric form. The form is filled with fine aggregate concrete and allowed to set for a minimum of one hour.A washer is then placed over the exposed end of the anchor rod, and a nut is installed Figure 55 snugly to secure the washer to the top of the lining or mat.

Page 35 Proper Storage and Handling of Fabric Forms Fabric forms are delivered at the job site in trailers or ocean containers. Fabric forms are stacked in a manner that as- sures ease of unloading.Standard 40 ft(12 m)long trailers or containers hold up to 215,000 ft2 (20,000 m2) of fabric forms per load. Armor unit fabric forms are normally shipped boxed.Alter- natively they may each be wrapped in two layers of protec- tive cover. The first layer (inner layer) is a waterproof, opaque, plastic cover the second (outer layer)is a woven, abrasion resistant,fabric cover. When fabric forms are to be inventoried at the job site,they should be kept dry and remain boxed so that they are pro- tected from the elements during storage and handling. If stored outdoors,they should be elevated and protected with a waterproof cover that is opaque to ultraviolet light. Care should be taken not to damage the fabric forms during un- loading, storage and handling. The contractor should un- load the fabric forms by hand or with a forklift or similar Width (unfilled) equipment. When lifting fabric forms make sure that work- ers have proper back support. Contraction of HYDROCAST Armor Units R= 0.5T The definition drawing, Figure 61, illustrates the change in T width that occurs when a fabric form is filled with concrete to form an armor unit.Table 12.0 is a guide in determining the required dimensions of an unfilled fabric form for cast- ing a given concrete armor unit size.

Note: The concrete-fitted thickness of the fabric form should be not more than 70 percent of the width of the unfilled fabric form. Page 36 Installation of HYDROCAST Armor Units Equipment and Tools Because of the simple installation procedure for HYDROCAST Armor Units, a nominal amount of tools and equipment are required. We suggest that the contractor have on hand the following: Tools: Surveyor's level and rod Shovels Rakes Hammers Stakes String line Rubber boots and gloves Pail Safety glasses or goggles Scissors Trowels Equipment: Small line concrete pump Concrete pump hose-2 inch (50 mm)diameter Injection pipe-2 inch (50 mm)diameter Hand-held sewing machine (electric or air powered) with speed control Extension cord (if electrical equipment is used) Electric generator with ground fault circuit breaker Air compressor(for air powered sewing machine) Small,walk-behind flat or vibratory compactor for soil compaction A list of equipment manufacturers is provided in the appendi- ces. However Synthetex, LLC makes no warrantee nor guarantees the performance of equipment provided by an- other manufacturer. Sequence of Armor Unit Installation Once the area to be protected has been excavated, graded and compacted to the lines and grades specified in the Con- tract Drawings and Specifications, an installation crew, filter fabric(if required),fabric forms, and the tools and equipment listed above should be mobilized to the job site. Freshly ex- cavated and graded slopes are highly subject to erosion and should be protected from water runoff, flowing water and waves. Depending on the location of the area, dimensions, and the rate of subgrade preparation, installation rates of as much as 15 yd3 (11.5 m3)of fine aggregate concrete per hour can be achieved by a crew of 3 or 4 laborers, a concrete pump op- erator and a supervisor. Establish the starting point. The first step in the installation of fabric-formed concrete ar- mor units is to establish a starting point. If a working point and direction of placement are shown on the Contract Draw- ings this should be the starting point. If this is not the case, it is the customary practice for channels,streams and rivers to work from the upstream end of the project to the downstream end. In this manner the flow of the water will tend to spread Page 37 the fabric forms out ahead of the finished work and Surveyors Level ��o the finished concrete armor unit is protected from g undercutting. For inland and coastal shorelines it is Alignment Line. °° °a• •- customary practice to install the first course of ar ° mor units then proceed to succeeding courses. Fab " r/c form armor unit layout drawings, available from Synthetex will recommendsiarting points • and directions of placement for the project Armor Unit form Establish the alignment lines offset 5 ft.from alignment lines Once a starting point has been established a = s • surveyor's level should be used to determine the Ion- gitudinal and slope alignment lines of the fabric- formed concrete armor units.String lines should then a . ` be placed along the respective alignment lines and staked. Generally,the alignment lines are offset, by • a measured distance, to the opposite side of any trench or a minimum of 5 feet(1.5 m)in order not to interfere with the work area. The method of estab- • /fishing reference points and lines should be left to • the discretion of the contractor Placement of the filter fabric, if required a > • Under certain soil conditions or if called for in the Contract Drawings and Specifications,it will be nec • - essary to place filter fabric and/or a granular sublayer Figure 62 under the fabric forms to guarantee that soil is not piped through any spaces between the armor units. Filter fabric should be selected and placed in accor- dance with the Contract Drawings and Specifications or in the absence of such directions in accordance with the manufacturer's guidelines. Filter fabrics and their installation are discussed,in brief,earlier in this manual(page 7)- Placement of the first course of armor unit fab- ric forms The prefabricated armor unit forms are folded and marked with the appropriate form numbers and di- mensions at the factory for easy identification, loca- tion and installation. The first armor unit fabric form, in the first course, should be carefully placed at the designated starting point and unfolded into position (Fig 62). Special care should be taken to assure than the sides and ends of the form are exactly parallel to their respec- tive alignment lines. Armor unit fabric forms should be placed loosely,but without folds, to allow for proper filling with fine ag- gregate concrete.The extra fabric provided for form contraction should be extended, Forms that are stretched or taut will not permit the required form contraction, therefore the fabric forms will not fill to their required thicknesses. For example, a 72 inch by 120 inch(183 cm x 305 cm)form is to be filled to a thickness of 30 inches (76 cm). When filled with fine aggregate concrete to this thickness,the width and length of the form will contract by approximately 57% of the thickness, giving a finished armor unit dimension of 55 inches x 103 inches(139 cm x 261 cm).Adjacent armor units(of the same dimensions Page 38 o used in this example)should therefore be placed with ° 6 ° their centers 17 inches(43 cm)closer together than °° °9• called for by the unfilled form dimensions. • The second armor unit form in the first course should v 6 ' ° • _ be placed alongside the first form so that the centerline to centerline distance equals that of the calculated armor unit width after contraction, as [ shown in Figure 63.After the second armor unit form has been positioned, the alignment of the forms • Centerline to should be checked. centerline The remaining armor unit forms in the first course -- distance should be placed side-by-side in the same manner. The alignment of the forms should be checked peri- odically since small errors in alignment can progress in severity.Armor unit form alignment is important in Second form overlaps first to compensate providing a uniform and attractive appearance in the for narrowing during filling finished installation. Armor unit form placement should precede concrete filling by no more than the distance that can be corn- ' °% a . p/eted in one day. Where the forms maybe exposed to flowing water or wave action, each form should ° be filled with fine aggregate concrete prior to pace- meet of the adjacent form. Figure 63 Placement of the second course of armor unit fabric forms The second course of armor unit forms should be placed atop the fine aggregate concrete filled first course. (See Sequence of Fine Aggregate Concrete Pumping.)The center line of the first form in the sec- ond course is positioned directly over the abutting edges of the first two armor units in the first course, as shown in Figure 64. The staggering of the centerlines of the armor units in vertically adjacent courses encourages "nesting" of armor units and facilitates alignment.The remaining forms in the sec- ond course should be placed side-by-side in the Second course units are centered same manner as the first course.Once again,check over the abutting edges of the alignment periodically since small errors can units in the first course. progress in severity. c, dowel When constructing structures subject to wave ac- tion,the armor units should be aligned with their long IMOstaple axis facing the principal direction of wave attack.

Figure 64 A small quantity of bulk (uncut and unassembled) form fabric should be ordered for each project. The fabric can be used for special field tailoring.At least one half a roll, about 900 ft2(84 m2)of bulk fabric, is recommended. Page 39 Sequence of Fine Permissible Fabric Stress(%) Aggregate Concrete Pumping Ordering fine aggregate concrete Fine aggregate concrete is generally delivered to the job site in ready-mix trucks. The order for concrete should be placed a least one day prior to its sched- 100 uled delivery to the job site. The concrete supplier should be instructed to fill the water tank of each truck with mix water.

The addition of pea grave/to the mix may reduce the cost of mated- *Recommended maximum T is 0.5 W a/s with a slight increase in labor costs. When pump- ing concrete with pea gravel the diameter of the Figure 65 pump hose should be increased. Securing the armor unit forms Beginning at the designated staring point the instal- lation crew should check and adjust the armor unit forms to assure that they are in alignment.After the forms have been properly adjusted, fine aggregate concrete is pumped into forms. /t must be empha- sized that care should be exercised in the alignment and securing of the first course of armor units. This will ensure the aesthetics of the concrete armor units and also hasten the installation of subsequent courses.

The forms in the succeeding course are then threaded over the exposed reinforcement bar ends. The dowels are then forced through the bottom layer of the vertically adjacent fabric form (Fig. 68), and the form is then filled with fine aggregate concrete. Armor units may be connected side-by-side by in- serting staples; bend the reinforcement bars into an elongated "U" shape and force the pointed ends of the reinforcement bars through the fabric and into the fresh concrete of the filled armor units.The dow- els and staples assist in holding the forms in place during filling and maintaining the alignment of the armor unit structure.Abutting armor units, if placed laterally, may be installed immediately after place- ment of the preceding unit(s). If an armor unit is to bear on previously installed units, the lower units II must be allotted a minimum of four hours of cure 1 time before beginning installation of a succeeding, } #, I l I . vertically adjacent course of armor units. t •i•-• WA: • •,�;QOrit• • • • •r•x Where required, reinforcement bar cages are in- N.cr „��awa a�� .�. • , ,, •V•,W �•• . t� stalled in the forms through openings in the forms. !

Circumferential straps may be attached to armor unit forms as thickness indicators to facilitate the filling of forms underwater. Slight depressions formed by the straps in the surface of the armor unit indicate to the diver, working by touch, that the form has been filled to the specified thickness. Circumferential straps of predetermined circumfer- ences and spacing,with or without external restrain- ing reinforcement bars, permit the casting of taper- ing or irregularly shaped armor units.

Armor unit forms should be tailored in the field to fit around pipes, culverts, trees, and other appurtenances.A form may be field cut and sewn or bulk fabric may be fabri- cated to fit snugly around the object. Backfilling and compaction of trenches The backfilling and compaction of open excavations should not begin until at least one hour after filling the adjacent concrete armor unit. Backfill material may be either select bedding materials or fine aggregate con- crete.The excavations should be backfilled as shown on the Contract Drawings. The open excavations behind completed sections of armor units should be back/il/ed and compacted by the end of the work day. Foot traffic Foot traffic on the freshly pumped fine aggregate con- crete armor unit should be avoided for a period of not less than one hour after concrete injection or until the concrete is resistant to indentation. Should traffic be un- avoidable,the contractor should place board walks along the finished filled concrete areas. This will reduce the amount of objectionable indentation. Footprints wi//leave permanent impressions in the installed fabric-formed concrete armor units. Cleanup Any fine aggregate concrete that may spill on top of the fabric-formed concrete armor unit should be picked up by hand or trowel and the surface smoothed by cloth or broom.Such unnecessary spillage of concrete will cause an unsightly appearance. This is particularly important along the top of the final course of armor units. The installation crew should be instructed to carefully "kink"the concrete pump hose when it is moved from one injection point to another or to place the end of the concrete injection pipe in a pail when moving the con- crete pump hose.
