The rubber dam is mainly composed of civil construction, dam bag and anchor, filling and drainage facilities (gas) and control system components. Rubber dam operation should be carried out in strict accordance with the provisions of the scheme and the operating rules, we should pay attention to water filling dam bag (gas) pressure should not exceed the design pressure, in order to avoid the dam burst. Rubber dam although little maintenance, unlike the conventional steel gate that need regular brushing of anti rust paint, but also should be inspected periodically, especially after the flood, to check whether there is debris caused by stab of dam bag and the dam, dam bag vibration, and plate wear, friction and impact caused by gravel dam damage. Rubber dam vulnerable to sharp andIt has damaged the object, it should draw the scope of management and safety of rubber dam project.
The rubber dam is mainly suitable for low head, large span gate dam project, such as for reservoir spillway as the gate or overflow weir, to increase the storage capacity of the reservoir and the power head; for the river as low head, large span of the overflow dam or weir, hoist without conventional gate, bridge for work; the canal as the intake sluice gate, control gate, and can conveniently adjust the water level and water flow along the coast; for as the breakwater or tidal gate, are not affected by the water erosion and marine life, than the metal gate with good effect; in the large span of the lock hole on the downstream gate for construction or activities around the cofferdam;Weir, rubber activities cofferdam height can go up or down, and from the weir overflow weir, do not need to borrow to build can keep the river clean, save labor and shorten the construction period; for urban landscape engineering, the dam is elegant, color, smooth lines, can add a beautiful landscape for the city construction.
