底拖牵引法管道穿越河流施工技术

Pipeline Crossing Construction Using Bottom Towing Technique

文章以忠武输气管道工程襄樊支线汉江穿越工程为例,针对施工地段的工程地质和水文条件,对底拖牵引法管道穿越河流技术的管沟开挖和测量、浮筒设计、牵引力计算及钢丝绳的选择等主要技术内容进行了介绍。

Taking the pipeline crossing Hanjiang river in Zhongxian to Wuhan nature gas pipeline project as an example and according to the geological and hydrologic conditions, this paper describes the main techniques of pipeline bottom-towing method, including ditch excavation and survey, buoy design, towing force calculation, steel wire selection.
