地铁深基坑地下连续墙围护结构施工技术综述

Construction Technology of Underground Continuous Wall Retaining Structure for Deep Foundation Pit of Subway

目前地铁深基坑项目已经普遍选择地下连续墙支护结构,因为该结构能够长期维持承重,并具备良好的挡土、止水性能。本文选取了某个地铁工程作为对象,研究了该技术在工程中的实际应用,在确定施工方案的基础上,详细叙述了其施工过程步骤:具体包括测量放线、导墙施工、泥浆配制及使用、槽段开挖等内容,最终取得了良好的施工效果。

At present,the underground continuous wall supporting structure has been widely used in deep foundation pit projects of subways,because the structure can maintain the load for a long time,and has good soil retaining and water stopping performance.The article selects a subway project as the object to study the practical application of the technology in the project.Based on the determination of the construction plan,the construction process steps are described in detail,including measuring and laying out,guide wall construction,mud preparation and use,The trench section excavation and other contents finally achieved good construction results.
