潜埋暗挖与顶管复合技术在管道工程中的应用

Application of combined construction technology of buried excavation and pipe jacking in pipeline engineering

针对城区内越来越难以采用大开挖技术进行管道工程施工的现状,介绍了常见的管道工程非开挖技术。采用潜埋暗挖和顶管复合施工技术对某再生水厂内部管道进行施工,介绍了复合方法的施工步骤和参数选择,最终顺利完成工程建设,可为类似项目提供参考。

In view of the fact that it is more and more difficult to adopt large excavation technology to carry out pipeline engineering construction in urban area,the common trenchless technology of pipeline engineering is introduced.The combined construction technology of buried excavation and pipe jacking was used to construct the internal pipeline of a reclaximed water plant.This paper introduces the construction steps and parameter selection of the composite construction method,and finally completes the project successfully.It can provide reference for similar projects.
