污水管道顶管施工技术及后座墙受力计算

Construction Technology on Jacking Sewage Pipe and Calculation of Back-wall Force

结合开封市一渠六河项目D800污水顶管施工,介绍了顶管施工的整个过程,特别是详细地对顶力和后座墙土体进行了受力计算,便于保证工作坑的安全,防止后座墙土体破坏,为顶管工程施工提供了参考。

Combined with the D800 sewage pipe jacking construction of Yiqu-Liuhe Project in Kaifeng, this paper introduced the whole process of pipe jacking construction, especially with the detailed stress calculation of the jacking force and back- wall soil, so as to ensure the safety of working pit and prevent the destruction of the back-wall. It could provide a reference for the construction of pipe jacking engineering.
