悬臂灌注排桩和止水帷幕在基坑工程中的应用

The Application of Cantilever Pouring Soldier Pile Wall and Waterproof Curtain in Foundation Pit Engineering

悬臂灌注排桩和止水帷幕作为基坑支护工程中较常见的支护体系组合,广泛运用于各类基坑支护工程。文章以城市主城区一周边老旧建筑物较多的项目为例,通过基坑特点分析、支护方案选择、支护体系计算进行基坑支护方案设计,拟采用悬臂灌注排桩和止水帷幕支护体系。通过对基坑支护体系和周边建筑物环境的变形监测分析,验证了以悬臂灌注排桩和止水帷幕为主要支护体系的支护效果,为此类项目支护体系的选择和施工质量的控制提供了思路参考。

As a common support system combination in foundation pit support engineering,cantilever pouring soldier pile wall and waterproof curtain are widely used in various types of foundation pit support engineering.Taking a project with many old buildings around in the main urban area as an example,through the analysis of the characteristics of the foundation pit,the selection of the support scheme and the calculation of the support system,the design of the foundation pit support scheme is carried out,and the cantilever pouring soldier pile wall and waterproof curtain support system are proposed.Through the analysis of the foundation pit support system and the deformation monitoring of the surrounding building environment,the support effect of the cantilever pouring soldier pile wall and the waterproof curtain as the main support system is verified,which provides a reference for the selection of the support system and the control of the construction quality of such projects.
