摘要
以上海市白龙港污水处理厂为例,对在长江入海口地区复杂地质条件下,超大超深基坑施工过程中的降水作业方式及其综合运用进行了系统的分析研究。并对轻型井点降水、深井井点降水及集水明排作业等工艺进行优化,满足了超大超深基坑施工作业中对降水的需求。介绍了该种组合降水方式在基坑施工中的综合应用,可为类似工程提供借鉴。
Taking Shanghai Bailonggang Sewage Treatment Plant as an example, the systematic analysis and research on the precipitation operation mode and its comprehensive application in the construction process of super large and deep foundation pit under the complex geological conditions of the Yangtze River estuary area is carried out. The optimization of light well point precipitation, the deep well point precipitation and the catchment and waterway drain operation is carried out to meet the demand for precipitation in the construction of super large and deep foundation pits. This paper introduces the comprehensive application of such combined precipitation method in foundation pit construction, which can provide reference for similar projects.
