橡胶坝是20世纪50年代末,随着高分子材料工业的发展而出现的一种新型水工建筑物。它是用高强力合成纤维织物做受力骨架,内外涂合成橡胶作粘结保护层,加工成胶布,按要求的尺寸,锚固在混凝土基础底板上,成封闭袋形,用水(或气)的压力充胀,形成挡水坝。橡胶坝具有造价低、节省三材、施工期短、结构简单、自重轻、抗震性能好、不阻水和止水效果好等特点,但同时也存在着坝袋坚固性较差、易老化、使用寿命较短等缺点。
Rubber dam is the late 1950s, with the development of polymer materials industry emerged a new type of hydraulic structures. It is made of high-strength synthetic fiber force frame, inside and outside coated synthetic rubber as a protective layer of adhesive, processed into tape, according to the required size, anchored in the concrete foundation floor, into a closed bag-shaped, water (or gas) Pressure inflation, the formation of retaining dam. Rubber dam has the characteristics of low cost, saving three materials, short construction period, simple structure, light weight, good seismic performance, no water blocking and water stopping effect, etc. However, Short life and other shortcomings.
