厚淤泥层地下连续墙的施工技术处理

Technical Treatment for Construciton of Diaphragm Wall of Thick Mud Layer

某厚淤泥层深基坑围护结构采用地下连续墙,按照常规指标施工地下连续墙过程中,常常发生塌槽;通过采用提高泥浆比重、成槽机上路基箱等技术措施后,达到了安全、可行的目的。

The diaphragm wall is used for curbing some deep foundation pit of the thick mud layer,but the groove collapse would happen during construction of the diaphragm wall auordiny to routine index.The safety and practical feasibility can be reached after increasing the specific gravity of mud and making the groover working on the subgrade boxes.
