地铁建设项目如火如荼的开展,使得基坑开挖工程也相应增多。但是在基坑开挖过程中,围护结构渗漏现象时有发生,不仅影响到基坑的开挖进度和安全,还会危及到周边道路及建筑物的安全。因此本文首先简要分析了地铁车站围护渗漏的主要原因,接着就其堵漏施工技术展开详细探讨。
Subway construction projects in full swing carried out, making a corresponding increase in excavation works. However, during excavation of the foundation pit, seepage phenomena of the retaining structures occur from time to time, which not only affects the excavation progress and safety of the foundation pit, but also endangers the safety of the surrounding roads and buildings. Therefore, this paper first briefly analyzes the main reasons for the leakage of metro station envelope, and then discusses in detail its plugging construction technology.
