水壩/Rubber Dam

  橡膠壩適用于低水頭、大跨度的閘壩工程。橡膠壩可用于防洪、發電、供水、航運、擋潮及城市園林美化，也可用于活動圍堰、渠系臨時擋水工程等。

  橡膠壩具有造價低，工期快，運行規范，維修方便，抗震能力強。美化環境，高度可調節等諸多優點。

  壩帶膠布由承受壩袋張力的骨架材料和確保氣密性的橡膠層構成。

骨架材料：橡膠壩對骨架材料的要求是承受沖漲壓力，具有抗刺穿能力，可選擇強力棉綸帆布或鋼絲網。

橡膠層：通常分為外層、中層、內層橡膠。

外層橡膠：由于河流中漂浮物較多，外層橡膠應具有耐磨損、耐日照、耐熱、耐臭氧等性能。

中層橡膠：對兩層或多骨架材料起連接作用，應具有較好的粘合性。

內層橡膠：應具有較高的水密性和氣密性。

Rubber dam is a new type of hydraulic structure compared with steel sluice gate , and made of high - strength fabric adhering with rubber , which forms a rubber bag anchoring on basement floor of dam bag . Filing water or air into the dam bag , rubber dam is used for water retention . Emptying water or air form the dam bag , it is used for flood release . Rubber dam has many advantages compared to conventional weirs , such as low cost , simple hydraulic structure , short construction time , perfect seismic performance and effect of stopping leading , and low resistance to water flow in flood season.
