深大基坑地下连续墙缺陷应急处理技术研究

Research on Emergency Treatment Technology of Underground Diaphragm Wall Defects in Deep and Large Foundation Pit

分别结合佛山地铁3号线的某车站与合肥地铁4号线的某车站两个工程实例,对深大基坑地下连续墙缺陷原因及应急处理技术进行探讨,并针对性地提出了相关质量控制方法以及处理措施,在保证工程顺利运行的同时提高工程经济效益,该质量控制方案取得了良好的效果。

Combined with two engineering examples of a station of Foshan Metro Line 3 and a station of Hefei Metro Line 4,this paper discusses the causes of underground diaphragm wall defects in deep and large foundation pit and the emergency treatment technology,and puts forward relevant quality prevention methods and treatment measures to ensure the smooth operation of the project and promote the economic benefits of the project.The quality control scheme has achieved good results.
