水利水电工程建设施工围水清基所用的抽水设备一般仍为潜水泵、离心泵,而离心泵又是最为常用的。水利水电工程建设在围水清基中,由于抽水时间长,或是反复使用的次数多,或是在搬运中的碰撞或是在抽水安装过程中的不慎等原因,都有可能引起水管破裂,破裂孔洞大时,可事先进行处理,当孔洞小,难以发现,直到水泵安装完毕抽不出水时,方知吸水管破裂漏 Water conservancy and hydropower projects surrounding the construction of clear water pumping equipment used are generally submersible pumps, centrifugal pumps, and centrifugal pumps are the most commonly used. Water conservancy and hydropower engineering construction in the surrounding water base, due to pumping a long time, or repeatedly used more frequently, or in the handling of the collision or in the pumping installation of the accidental and other reasons, may cause water pipe rupture , Broken hole large, can be processed in advance, when the hole is small, difficult to find, until the pump is installed without pumping out of water, to know the suction pipe rupture leak
