橡胶坝是本世纪五十年代末出现的一种新型低水头水工建筑物。1957年以来,相继在许多国家兴建,并不断扩大其使用范围。由于它具有独特的优点,故发展较快。作为薄壳柔体水工结构,橡胶坝已自成体系。橡胶坝是用高强力合成纤维织物做受力骨架,内外涂敷合成橡胶作粘结保护层,成为高强胶布,再按要求的尺寸加工成封闭袋形,锚固在混凝土基础底板上,用水(或气)的压力充胀,形成挡水坝。不需要挡水时,泄空坝袋中的水(或气),便可恢复原有泄流断面。坝高可调节,坝顶可
Rubber dam is a new type of low-head hydraulic structure appearing in the late 1950s. Since 1957, one after another in many countries to build, and continue to expand its use. Because of its unique advantages, it developed rapidly. As a flexible shell hydraulic structure, rubber dam has its own system. The rubber dam is made of high-strength synthetic fiber as the force frame, coated with synthetic rubber inside and outside as a protective layer of adhesive, a high-strength tape, and then processed into a closed bag size according to the required size, anchored on the concrete foundation, water (or Gas) pressure inflation, the formation of retaining dam. When no water is needed, the water (or gas) in the dam bag can be restored and the original discharge section can be restored. Dam height adjustable, dam crest
