TM 5-5420-278-100035 000035 00-8BRIDGE ANCHORAGE (Contd)SHORE GUY ANCHORAGEa. Planning considerations. Shore guys are cables attached from the bridge todeadmen or similar holdfasts on the shore. Shore guys can be used as upstream ordownstream anchorage systems provided that the maximum anticipated current (orreverse current for downstream systems) does not exceed 3 feet/sec (0.9 meters/sec).Shore guys may be used for any length of floating bridge provided that a 45-degreeangle can be maintained between the shore guy and the bridge centerline.b. Materials. Shore guys consist of steel cables attached to deadmen. The cableused for shore guy systems should be 1/2-in. (12.7-mm) IPS cable or any cable whichhas a comparable breaking strength. The length of these cables depends primarilyupon the length of the bridge and the shore conditions.c. Installation.(1) When shore guys are used as the upstream anchorage system for a bridge,they are emplaced as the bridge is constructed. (Refer to figure 7.) The cableshould be unreeled from the shore and passed out along the bridge. Ifnecessary, station one person at every other float to hold the cable out of thewater. Connect guys to the IRB load receiving pins only.(2) Tighten the shore guys that were attached to the bridge during the bridgeassembly just enough to hold them taut. After bridge completion, tighten thefour approach guys simultaneously to prevent longitudinal movement. Thentighten the shore guys simultaneously to maintain bridge alignment. Shoreguys must stay above the water to prevent whipping and accumulation ofdebris. If necessary, use an A-frame or some other means of intermediatesupport to raise the guys clear of the water.
