旋挖成孔法在地下连续墙施工中的应用

The application of rotary excavating pore-forming method in underground continuous wall construction

以临汾地区某高层住宅楼基坑工程为研究对象,在对地下连续墙施工的各种方法进行对比分析的基础上,介绍了卵砾石地层下旋挖成孔法在地下连续墙施工中的应用,并对接头方法和后压浆工艺在施工中的应用进行了分析,工程实践证明,应用该方法其施工效果良好。

Taking the foundation pit engineering of a high-rise building in Linfen as the research object, based on comparative and analysis on va- rious methods for underground continuous wall construction, this paper introduced the application of drop rotary excavating pore-forming method of gravel stratum in underground continuous wall construction, and analyzed the joint methods and the application of post grouting technology in con- struction, the project practice proved that, using this method had good practice effect.
