摘要
文中以深圳东湖水厂扩能改造工程为例,提出了一种灌注桩与旋喷桩复合止水帷幕的施工技术.该技术利用灌注桩的高刚度和旋喷桩的隔水效果,实现基坑的稳定性、防渗性和平面布置的灵活性,缩短了工期,减少了对周边环境的影响,提高了场地和基坑内的作业空间,保障了施工安全.
Abstract
In order to solve the problem of foundation pit construction in the high groundwater level area near the lake,this paper takes the ex-pansion and renovation project of Shenzhen East Lake Water plant as an example,and puts forward a construction technology of the composite water curtain of cast-in-place pile and rotary jet pile.This technology uses the high stiffness of the cast-in-place pile and the water insulation effect of the rotary jet pile to achieve the stability of the foundation pit,seepage prevention and flexibility of the plane layout,shorten the con-struction period,reduce the impact on the surrounding environment,improve the working space of the site and the foundation pit,and ensure the construction safety.
