大断面矩形顶管施工监理控制要点

Key Points for Construction Supervision Control of Large Section Rectangular Pipe Jacking

在城市地下空间的开发过程中,矩形顶管技术应用越来越广泛。该工艺对环境的影响较小,不需要对地面空间进行重大改变,不妨碍交通、短期工作、建筑安全以及较低的综合成本。研究大断面矩形顶管是施工要求,提出质量控制要求,对类似工程有借鉴作用。

In the development process of urban underground space,the application of rectangular pipe jacking technology is more and more extensive. The impact on the environment is small and there is no need to make major changes to the floor space,without impeding traffic,short-term work,building safety and lower overall costs. Studying the large-section rectangular pipe jacking is the construction requirement,and puts forward the quality control requirements,which can be used as a reference for similar projects.
