摘要
以郑州市郑东新区康庄社区A区深基坑工程为例,论述了管井与轻型井点组合降水施工工艺及方法,该降水方法即满足了深基坑的有效降水深度,又解决了基坑坡面因滞水层导致的渗水涌砂问题,保证了基坑的安全稳定和土方开挖等施工需要。
Taking the deep foundation pit project in zone A,Kangzhuang community,Zhengdong new district,Zhengzhou city as an example,this paper discusses the construction technology and method of combined dewatering of pipe well and light well point.The combination of two types of precipitation not only satisfies the effective dewatering depth of deep foundation pit,but also solves the problem of seepage and sand gushing caused by stagnant water layer on the slope of foundation pit,thus ensuring the safety and stability of foundation pit and the construction needs of earthwork excavation.
