深层搅拌桩在污水管道顶管施工中的应用

Application of deep mixing pile in sewage pipeline pipe-jacking construction

就软土地质条件下的污水管道顶管施工进行了研究,提出了采用深层搅拌桩预加固的技术路线,并阐述了主要的施工流程及技术优势,较好地解决了污水管道穿越和施工中所遇到的难题,取得了良好的社会效益和经济效益。

The paper studies sewage pipeline pipe-jacking construction under soft soil geology conditions,puts forward deep mixing pile pre-reinforcement technology route,describes major construction procedures and technological merits,and better solves sewage pipeline crossing problems and achieves good social and economic benefits.
