以天津海河“共同沟”刘庄桥隧道盾构始发工作井渗漏现象为例,在分析产生渗水原因的基础上,从前期应急处理、后期高压旋喷抗渗墙施工、基坑抽水等方面采取一系列抗渗漏措施,并取得良好的堵漏效果,能够为类似工程施工提供参考。 Taking the leakage of the working well in shield tunnel of Liuzhuangqiao Tunnel in Tianjin Haihe River as an example, on the basis of analyzing the causes of water seepage, from the pre-emergency treatment, the later high-pressure rotary jetting impervious wall construction, the foundation pit Pumping and other aspects of a series of anti-leakage measures, and achieved good plugging effect, to provide reference for similar projects.
