大直径顶管施工技术研究

Research on Large Diameter Pipe Jacking Technology

随着城镇化建设发展及城市品质的提高,城市地下管道建设工程日益增加,顶管技术作为非明挖施工手段市场发展潜力巨大,同时对管径、顶进距离、覆土深度、地质条件也提出了更高的要求,本文以西安市酒十路顶管工程为实例,分析市政大管径顶管施工技术。

With the development of urbanization and improvement of urban quality,the urban underground pipeline construction projects are also increasing.The pipe jacking technology,being a trenchless construction means,has huge market development potential and puts forward higher requirements for pipe diameter,jacking distance,covered depth and geological conditions.This paper takes the pipe jacking project of Jiushi Road in Xi'an as an example,and analyzes the pipe jacking technology of municipal large-diameter pipe.
