面网式盲沟排水系统在基坑渗漏处理中的应用

The Application of Surface-Net Blind Ditch Drainage System in Foundation Pit Leakage Treatment

基于某基坑工程实例,分析基坑渗漏机理及处理方式,创新性地开发出面网式盲沟排水系统,并在工程中成功应用,通过土工布与级配碎石垫层形成导水面板,将地下水引入网状排水盲沟最终汇至集水井抽排基坑渗漏水体,有效解决了基坑中地下水渗漏的难题,取得了良好的效果,可为其他类似工程借鉴参考。

Based on an example of a foundation pit project, this paper analyzes the leakage mechanism and treatment method of foundation pit,innovatively develops the surface-net blind ditch drainage system, and successfully applies it in the project. Through the geotextile and graded gravel cushion, a water guide panel is formed, and the groundwater is introduced into the net drainage blind ditch to drain the leakage of foundation pit. It solves the problem of groundwater leakage in foundation pit, which can provide reference for similar projects.
