摘要
以高压旋喷注浆技术施作地下止水帷幕、有效解决紧邻小月河的地铁基坑开挖过程中出现的渗漏水问题为例,介绍旋喷桩防水帷幕的设计施工方法。帷幕形成1周后,基坑开挖施工,除局部位置有少许残存水外,基坑帷幕侧基本无明水,防水效果良好,保证了后续施工的无水作业,说明该防水帷幕的设计和施工都很合理,有效解决了施工中出现的漏水问题。
As an effective way to deal with the seepage occurring in the excavation process of the subway foundation pit adjacent to Xiaoyue River, mortar was grouted with high pressure around the pit outside to form a continuous row of piles and to create a waterproofmg curtain. The pit was excavated a week after the curtain had been formed. Seepage was well stopped around the pit, which proved the rationality of the design and construction of the waterproofing curtain This article introduces the design and practice of this technique in detail.
