Installation steps of rubber dam
Structure: 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 does not exceed the design pressure, in order to avoid the dam bag rubber dam blasting. 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. The dam is vulnerable to sharpAnd it is the object damaged, it should be out of scope of management and safety of rubber dam project.
The rubber dam in order to increase the reservoir capacity and power head; for the river as low head, large span of the overflow dam or weir, hoist can work without conventional gate, bridge and so on; for the canal system as inlet sluice, sluice gate, control gate, and can conveniently adjust the water level and water flow; for the coast breakwater or tidal gate, are not affected by the water erosion and marine life, than the metal gate effect is good; for the large span hole lock on the downstream gate; for construction cofferdam or cofferdam, cofferdam height of rubber activities can go up or down, and from the weir overflow, without the soil can keep the river clean weir building, save labor and shorten the construction period; for urban landscape engineering, the use of color dam bag, beautiful shape, smooth lines, can add a beautiful landscape of urban construction.
