橡胶坝是一种新型的低水头水工建筑物。它是以高强度合成纤维织物为受力骨架、内外涂敷合成橡胶作为特结保护层制成的胶布,锚固在混凝土底板上,封闭成袋形,用水(或气)充胀、排塌,以调节坝高,控制上游水位,发挥灌溉、防洪、挡潮、航运等效益。世界上第一座橡胶坝于1956年在美国建成,现已被很多国家广泛采用。我国在1963年开始研建,已先后在各地兴建了数百座功能各异的橡胶坝。我省第一座橡胶坝是1986年建于徐州市铜山县的程头橡胶坝。以后又陆续兴建了四座橡胶坝,其中倚宿坝单孔92.4m,是我省目前最长的橡胶坝,单孔长居全国第四位。
Rubber dam is a new type of low head hydraulic structure. The utility model is made of high-strength synthetic fiber fabric as the force frame, the inner and outer coated synthetic rubber as special knot protective layer made of adhesive tape, anchored on the concrete floor, enclosed in a bag shape, inflated with water (or gas) To adjust the dam height, control the water level upstream, irrigation, flood control, tide, shipping and other benefits. The world’s first rubber dam built in the United States in 1956, has now been widely adopted in many countries. China started construction in 1963 and has built hundreds of rubber dams with different functions around the country. The first rubber dam in our province was built in 1986 in Chengshan Xuzhou Tongcheng rubber dam. Since then, four rubber dams have been constructed one after another, of which 92.4m are single-seated in the temporary shelter dam, which is the longest rubber dam currently in our province and the fourth single hole in the country.
