建筑物下顶管施工遇孤岩处理技术

Solitary Rock Treatment Technology in Pipe Jacking Construction under Buildings

顶管施工是一种地下管道非开挖施工,受沿线地面建筑物及地质条件的影响较大,不可预见的因素很多。该文结合黄埔电厂天然气热电联产工程项目循环水暗涵顶管工程,介绍了建筑物下顶管机顶进过程中遇孤岩的处理技术。

Pipe jacking is a trenchless construction of underground pipelines, which is greatly influenced by the ground buildings and geological conditions along the pipeline. There are many unpredictable factors. Combining with the pipe jacking project of circulating water hidden culvert in the natural gas cogeneration project of Huangpu Power Plant, this paper introduces the treatment technology of solitary rock encountered in the jacking process of the pipe jacking machine under the building.
