摘要
地铁车站深基坑采用桥式滤水管降水井,运用真空泵+水泵接力抽水的手段进行降水,介绍了降水井施工工艺、降水原理、操作要点以及质量控制措施,并和类似降水方法进行对比,为类似深基坑降水提供了经验,并有一定的推广价值。
The deep foundation pit of the subway station adopts a bridge filter pipe to reduce the well,uses a vacuum pump to carry out precipitation,introduces the construction process,precipitation principle,operating points,and quality control measures for the drop well,and compares with similar precipitation methods. It provides experience for similar deep foundation pit precipitation and has a certain generalization value.
