Pipeline Crossing by Pipe Pushing Construction Technique

Taking the pipeline crossing Xishao North River in Yong-Hu-Ning Oil Pipeline Project as an example, this paper introduces a construction method of pipeline crossing river, i.e. pipe pushing. It depicts in detail the project outline, construction preparation, working flow and technical measures, focusing on the aspects of manufacture and positioning of the operation well and reception well, pushing process and deviation adjustment, the main technical measures for major pipeline crossing as well as some matters needed to pay attention in pipeline crossing the river.
