摘要
旋喷桩止水帷幕质量的好坏,直接关系到深基坑工程能否顺利地施工开挖,然而旋喷桩止水帷幕的质量检测却是深基坑工程中的一个重要难题。今以某工程为例,通过对实际工程地质情况及支护情况的说明,提出超深旋喷桩止水帷幕的钻孔取芯及深井抽水试验相结合的检验方法,探讨如何方便有效地进行超深旋喷桩止水帷幕的质量检测,以便对以后类似的超深基坑工程提供施工质量检查方法及经验。
Churning pile cofferdam＇s quality is directly related to the success of deep excavation＇s excavation . However churning pile cofferdam＇s quality testing is indeed an important and difficult problem in deep excavation .Based on the actual engineering geology and supporting conditions of an engineering project ,we put forward deep jet grouting pile drilling core and stop water heavy curtain combined inspection method of deep well pumping test ,discuss how to carry on conveniently and effectively quality testing to provide checking method and valuable experience for future similar deep foundation pit engineering .
