絞車清淤技術

水沖刷清淤法

水(shui)沖(chong)刷清淤一般(ban)通過(guo)能擋水(shui)設(she)備(例(li)如：氣囊(nang))把管道(dao)中的污水(shui)阻(zu)擋在其裝(zhuang)置(zhi)的上游，為水(shui)位(wei)達到一定高(gao)度(du)后便放(fang)水(shui)，使上游水(shui)形成水(shui)流來清除管道(dao)內的沉積(ji)物(wu)。沉積(ji)物(wu)沖(chong)走(zou)后，這個裝(zhuang)置(zhi)就向(xiang)下游移動一段位(wei)置(zhi)，再進行集水(shui)清淤。這種技術效率不高(gao)，所以，應用不廣泛。
