淤泥质砂土地层下穿高压燃气管的顶管施工技术分析

Construction Technology of Pipe Jacking Through High Pressure Gas Pipe Under Silt Sandy Soil

进入21世纪,随着城市功能的多样化,城市道路的使用功能日趋完善,管道(管廊)的顶进施工技术应用越发普遍。本文详述了城市主干道路建设中,顶管下穿高压燃气管道的施工技术,特别是在流塑状淤泥质粉细砂地质中,顶管施工时对高压燃气管道的安全防护要点。

In the 21st century,with the diversification of urban functions,the usage of urban roads is becoming more and more perfect,and the application of jacking construction technology of pipelines(pipe corridors) is particularly common.This paper describes the construction of urban trunk roads in detail.The construction technology of pipe jacking through high pressure gas pipeline,especially in the silt geology of flow plastic silt,the key points of safety protection for high pressure gas pipeline during pipe jacking construction.
