下沉式庭院挡土墙及防排水施工技术研究

Research on sinking courtyard retaining wall and waterproof and drainage construction technology

下沉式庭院挡土墙是指将地下室外墙打开,与下沉式庭院相连后,外侧起支承路基填土、防止土体变形失稳作用的墙体。再通过自防渗与防水卷材交圈,及找坡层与集水坑搭配潜水排污泵结合,最终形成具有下沉式庭院特色的防排水体系。文章以具体项目为例,对下沉式庭院挡土墙及防排水施工进行技术简析。

The sunken courtyard retaining wall refers to the wall that opens the basement outdoor wall and connects with the sunken courtyard,and the outer side plays the role of supporting the subgrade filling and preventing soil deformation and instability.Then through the intersection of self-proof seepage and waterproof coiled material,and the combination of slope finding layer and sump with submersible sewage pump,finally a waterproof and drainage system with sunken courtyard characteristics is formed.This article takes a specific project as an example to analyze the technology of sunken courtyard retaining wall and waterproof and drainage construction.
