地震断裂带管道敷设施工技术

Pipeline Laying Construction Technology in Seismic Fracture Zone

在西气东输冀宁管道沂沭地震断裂带施工中,按照设计要求,采取了大规模的水撼砂、管排井轻型井点降水、管排铺路等施工方法,圆满地完成了沂沭地震断裂带管道敷设的施工任务,为天然气长输管道穿越断裂带施工积累了宝贵的经验。

In construction of Jining Pipeline of the West to East Pipeline Project in Yishu seismic fracture zone, the design requirements were strictly complied. The construction methods and techniques such as sand compacted by pumping water, light well point drainage by two rows of wells, road paving with tube grids were adopted on a large scale,and the construction task of pipeline laying in Yishu seismic fracture zone was successfully fulfilled. The accumulated experience of long distance pipeline construction in seismic fracture zone is valuable.
