矩形土压平衡顶管技术在地铁施工中的应用

Application of rectangle soil-pressure jacking pipe technology in subway construction

针对城市地面交通繁忙,地下管线复杂的现状,以深圳地铁7号线地下矩形通道为例,采用土压平衡顶管法施工,介绍了大断面矩形顶管施工原理、工艺流程及关键控制技术,以期为今后类似工程的施工提供参考。

In light of busy city ground traffic and complicated underground pipeline status, taking Shenzhen subway line N 0. 7 rectangle channel as an example, applying soil pressure balancing jacking pile construction technology, the thesis introduces the large-section rectangle jacking pile construction principles, technological procedures and critical control techniques, with a view to provide some guidance for similar engineering construction in future.
