橡胶坝自动化补水系统研究

Study of Automatic Water-replenishment System of Rubber Dam

橡胶坝是一种新型水工建筑物,目前我国建设的橡胶坝多达4000多座。橡胶坝在运行中,由于坝袋锚固、闸阀关闭不严等原因,坝袋经常出现缓慢自行降坝,造成坝整体不均过流。目前,主要采用原有的充排系统为坝袋补水。这种方式在运行时需要同时开启多个较大阀门、大功率水泵,费时费力,增加运行成本。橡胶坝自动化补水消除了大泵补水产生的水锤效应,解决了水锤效应对蝶阀、机泵、管路的破坏问题,延长了机泵、蝶阀、管路的使用寿命,大大提高了橡胶坝工程的运行管理水平。

Dam is a new type of hydraulic structure,there are totally around 4000 rubber dams in China nowadays.In the process of the rubber dam operation,the height of rubber-dam-bag often decreases slowly automatically due to the elements of dam-bag-anchor or unfastened brake valve etc.The traditional filling-and-emptying system requires switching on several large valves and high-power pumps simultaneously,which consumes high operating costs.Automatic water-replenishment system eliminates the effect of water hammer,and extends the service lives of pumps,valves and pipes,which greatly improves the level of the operation and management of the rubber dam.
