市政综合管道穿越障碍物顶管施工设计和应用

Design and Application of the Municipal Integrated Pipelines Crossing the Obstacles Pipe Jacking Construction

在山东菏泽万福新城范蠡路道路工程新建市政管道穿越现状平泰线天然气输送管道(原西气东输管道)顶管施工设计中,采用多根市政管道共用顶管工作井穿越障碍物。施工对天然气管道基本不产生扰动,保证了障碍物的安全运行。顶管工作(接收)井位置修建巨型检查井,满足城市基础设施使用及检修要求。该设计可为市政管道在同一顶管工作井穿越地下重要设施设计提供参考和依据。

Taking the pipe jacking design of the new municipal pipe as an example,the natural gas transmission pipeline project of Pingtai (the original pipeline of natural gas transmission from West to East China) was constructed in the road project of Fanli Road,Wanfu New Town,Heze City,Shandong Province. The design process of municipal pipelines sharing the pipe jacking well to cross obstacles was introduced. The process of construction basically did not disturb the natural gas pipeline,which ensured the safe operation of obstacles. The construction of giant inspection wells at the location of pipe jacking work (receiving) wells could meet the requirements of urban infrastructure use and maintenance. This design could provide reference and basis for the design of important underground facilities for municipal pipelines to pass through the same pipe jacking work well.
