基坑施工中的地下水处理

Groundwater disposal under the foundation ditch construction

分析土方工程施工中基坑开挖地下水的各种处理办法。结合工程实例,根据相应降水技术处理方案对比,选择深井井点降水,并进行优化设计。依靠深井泵将地下水从深井内扬升到地面排出,使地下水位降至坑底以下,达到降水施工简便、操作技术易于掌握,并保证工程质量与安全。

This article aims to analyze various processing methods for groundwater excavation of the foundation ditch in earthwork construction.Combining with case studies and based on a comparative study of processing scheme in dewatering technolongy,the author found it a good method to choose the deep well point dewatering and make an optimum design.In this way,by pumping the groundwater to the earth surface with deep well pump and declining the underground water level below the pit,it can simplify the dewatering co...
