在深圳市罗湖区东门某商住项目的深基坑工程采用了以地下连续墙成槽护壁、同时作为止水帷幕的施工技术。通过对地下连续墙施工过程中容易出现的夹泥、气孔、强度降低等问题进行了分析与预防,决定应用自密实混凝土作墙身主材,结果表明:自密实混凝土在泥浆中浇筑及强度保证等方面均具有良好性能。
Shenzhen Luohu District, the East Gate of a commercial project of deep foundation pit project uses underground continuous wall slotted wall, at the same time as a water curtain construction technology. Through the analysis and prevention of the problems such as the grime, porosity and strength which are easy to appear during the construction of underground continuous wall, the application of self-compacting concrete as the main body material of the wall body is determined. The results show that the self-compacting concrete is poured into the mud and the strength is guaranteed And so on all have good performance.
