论顶管施工过程控制要点分析

On controlling points for pipe-jacking construction process

结合临汾市尧都区东外环排水工程的实际情况,采取了机械式土压平衡顶管施工技术,从顶力计算、后背稳定性计算、触变泥浆减阻施工、施工监测等方面,阐述了顶管的施工过程控制要点,有利于促进顶管施工的推广应用。

Combining with the drainage project at Dongwaihuan Street at Yaodu District of Linfen,the paper adopts the mechanic earth pressure balance pipe-jacking construction,and illustrates the controlling points for the pipe-jacking construction process from the jacking force calculation,back stability calculation,thixotropic fluids anti-drag,and construction monitoring,so as to ensure the application of the pipe-jacking construction.
