摘要
重庆地区依山傍水,地质情况较为复杂,深基坑降水为施工时的一大难点。为指导施工,作者通过大量的调研和现场实践,对重庆地区深基坑管井降水工程设计进行了深入细致的研究。该文针对重庆地区特殊的地质条件,通过从管井井点布置设计、管井降水基坑涌水量计算、井点管数量和井距的确定等方面进行的相应研究,该文提出了管井降水施工技术要点。
Located in the mountainous region,Chongqing has complex geological conditions and deep Foundation pit dewatering has become a severe problem in construction.To guide relevant construction,the construction design of tube well dewatering in deep foundation pit in Chongqing is deeply studied.Based on the special geological conditions and related research in the design of tube well layout,calculation of water inflow in dewatering foundation pit,number of tube well and determination of well distance,key points of construction technology for tube well dewatering are presented.
