复杂地质下穿管线顶管施工技术分析

Analysis of Pipe Jacking Construction Technology for Underpass Pipelines in Complex Geology

以茂名市小东江流域城镇生活污水管网完善工程-县道x626污水主干管为例,对于在风化程度分布不均匀,强透水性的复杂地质环境及地下管线复杂交错环境下施工时,常规方法不能满足顶管机的正常顶进,因此,有必要针对这类复杂地层下顶管机的顶进施工技术进行研究,提出解决方案,确保顺利贯通。

This paper takes the improvement project of urban domestic sewage pipeline network in the Xiaodong River Basin of Maoming City-County Road x626 sewage main pipe as an example.When constructing in complex geological environments with uneven distribution of weathering and strong permeability,as well as complex and intersecting underground pipelines,conventional methods cannot meet the normal jacking requirements of the pipe jacking machine.Therefore,it is necessary to study the jacking construction technology of pipe jacking machines in such complex formations,propose solutions,and ensure smooth penetration.
