That is,at no time shall any cell be filled to a depth exceeding 1-foot(0.30 m)higher than the adjoining cell. It is also recommended to slightly overfill the baskets by 1 to 2 in. (25 to 50 mm) to allow for settlement of the rock. Behind gabion walls, compact the backfill material simultaneously to the same level as the filled gabions. 3.4 Internal Connecting Wires MacTie preformed stiffeners or lacing wire can be used as internal connecting wires when a structure requires more than one layer of gabions to be stacked on top of each other. Internal Connecting Wires with lacing wire shall connect the exposed face of a cell to the opposite side of the cell. Internal Connecting Preformed stiffeners shall connect the exposed face of a cell to the adjacent side of the cell. Preformed stiffeners are installed at 45° to the face/side of the unit, extending an equal distance along each side to be braced(approximately 1 ft.(300 mm)).An exposed face is any side of a gabion cell that will be exposed or unsupported after the structure is completed. 3.4.1 3 Feet(1 m)High Gabions 3 feet(1 m) high gabions shall be filled in three layers, 1 foot(300 mm) at a time. Connecting wires/bracings shall be installed after the placement of each layer,that is,at 1 foot(300 mm)high and 2 feet(600 mm)high. 3.4.2 1.5 Feet(0.5 m)High Gabions 1.5 feet (0.5 m) high gabions do not require connecting wires/bracings unless the baskets are used to build vertical structures. In some cases, these units shall be filled in two layers, 9 in. (230 mm)at a time. Connecting wires shall be installed after the placement of the first layer,which is at 9 in.(230 mm)high. 3.5 Lid Closing Once the gabion baskets are completely full, the lids will be pulled tight until the lid meets the perimeter edges of the basket.A tool such as a lid closer can be used.The lid must then be tightly laced and/or fastened along all edges,ends and tops of diaphragm(s)in the same manner as described in Section 3.1. MACCAFERRI PRODUCT INSTALLATION GUIDE __ Rev:01, Issue Date 04.01.2005 GABION Material Delivery Gabions are manufactured with all components mechanically connected at the production facility, as per ASTM A975-97. All gabions are diaphragm supplied in the collapsed form,either folded and bundled or rolled.The projecting selvedge wire bundles are compressed and strapped together at the factory for easy shipping and handling. Lacing wire is shipped in coils. Fasteners are shipped in boxes.Preformed corner stiffeners are shipped in boxes. ,4''1? I��j:. folding lines Assembly 0.0 \ —-, t Open and unfold each gabion on a flat, hard surface and remove any shipping fold if necessary.This can be done by placing the fold over a 2" - f x 4" board and walking along the sides. Lift up the sides, ends and W 41111111 diaphragms into a vertical position to form an open box shape(Fig.1). Connect the back and the front panels of the gabion to the end panels and center diaphragms. The top corner of the end panels and center diaphragms have the selvedge wire extending out approximately 4 in Figure 1- (102 mm) from these panel edges. Raise the end panels and the diaphragms to a vertical position and wrap the selvedge wire around the edge wire of the top and back panels. Connect the edges of the gabion and diaphragms by using either lacing P wire or ring fasteners(Fig.2). Ring fasteners shall not be spaced more than 6 in. (150 mm)apart.The procedure for using lacing wire consists of cutting a sufficient length of wire,and first looping and/or twisting the lacing wire to the wire mesh.Proceed to lace with alternating double and ---, single loops through every mesh opening approximately every 6 in.(150 --- mm) pulling each loop tight and finally securing the end of the lacing �� wire to the wire mesh by looping and/or twisting.The use of pliers to aid 4 i assembly and tying of the units using the lacing wire supplied with the 1 ,,%, gabions is normally recommended. ,I , lil 101,e��i�0 Erect the diaphragms into the vertical position,and tie them to the side 4:1�j1��j panels in the same manner. secure diaphragms oN..j to front and back p , • Fastening Procedure secure ends to side Ai When using lacing wire, cut off a piece of wire approximately 1.5 times the length of the edge to be tied.

Installation and Filling Cross ties with lacing wire Cross ties with pre-formed stiffeners After the foundation has been prepared,the pre-assembled gabions are placed in the desired location to form the structure. Gabions shall be connected together and aligned before filling the baskets with rock. All connections (panel-to-pane! and basket-to-basket) shall be already _ carried out as described in the assembly operations. 2- Rocks for gabions may be produced by any suitable quarrying method, ' ', and by the use of any device that yields the required sizes within the — — `^ -- gradation limits chosen. Rocks shall be hard,angular to round,durable ,r k-- %_. and of such quality that they shall not disintegrate on exposure to water , `' or weathering during the life of the structure. p Gabion rocks shall range between 4-8 in. (100-200 mm). The range in :—,; sizes may allow for a variation of 5%oversize and/or 5%undersize rock, ____ provided it is not placed on the gabion's exposed surface. In all cases, the oversize rock shall not be larger than 10 in. (250 mm), and the undersize rock shall not be smaller than 2 in.(50 mm).

Preformed corner stiffeners are installed at 45°to the face/ side of the unit, extending an equal distance along each side being Figure 6 braced(approximately 1 ft[300 mm]). Minimize the number of voids by using a well-graded stone and avoid large stones in order to achieve a dense, compact stone fill. All corners should be securely connected to Phase 1 the neighboring gabions of the same layer before filling the units. When more than one layer of gabions is required, in order for the :4 individual units to become incorporated into one continuous structure, -z` - _- `%r:t - _y_ - .i.- .• _ , the next layer of gabions must be connected to the layer underneath after this layer has been securely dosed(Fig.8).
