摘　　要：随着西气东输的大建设,以兰州-郑州-长沙成品油管道工程中的一处穿越河流的施工工艺为例,详细介绍漂管沉降技术在管道穿越河流中的应用。其中着重介绍了水下管沟的开挖以及测量、稳管及沉管、管沟回填等施工工艺。该方法的优越性主要体现在操作简单、工期比较短、经济效益显著、对环境影响小,特别适用于南方多河流地区的大中型河流的管道穿越。During construction of the west-east gas transmission,taking the construction process of crossing a river course in Lanzhou-Zhengzhou-Changsha products pipeline engineering as an example,application of the drift tube settlement technology in the pipeline crossing river was introduced.Some construction processes were emphatically introduced,such as excavation,measurement,sinking pipe,backfill and so on.Advantages of this method are simple operation,shorter construction period,remarkable economic benefit,so the method is suitable for the pipeline crossing construction of large and medium-sized river course.

关 键 词：管道穿越 漂管 施工技术.
