管井井点降水在七孔闸工程施工中的应用

Application of pipe well point dewatering in construction of Qikong Gate Project

结合七孔闸工程消力池段工程地质条件,通过方案比选,选定管井井点降水方法为该工程基坑排降水,并介绍其设计计算及施工要点。方案实施后,达到了预期效果,确保了消力池段的顺利完工,其经验可供类似工程借鉴。

For the foundation pit dewatering of stilling basin construction of Qikong Gate Project, pipe well point dewatering was adopted after schemes were compared combining with the engineering geological conditions. An instruction was made on the key points of design and construction. The adopted scheme had been implemented with the desired effects achieved, ensuring successful completion of the stilling basin.
