- 摘要:
- 黑河是西部管道工程采用大开挖方式穿越的距离最长的河流，原油与成品油管道采用同沟敷设方式穿越该河流。文章介绍了穿越段的工程概况以及管道整体预制、管沟分层开挖、管道整体下沟和整体试压等一系列新的施工方法，该方法加快了施工进度，节约了施工费用。
West Pipeline crossing Heihe River is the longest crossing project by a large excavation way and the method of laying both crude oil pipeline and products pipeline in a single trench. This paper depicts the engineering outline of the pipeline crossing project as well as a series of new construction methods such as integral pipeline prefabrication, trenching layer by layer, integral lowering pipeline into trench and integral pressure testing, which speed up the construction progress and reduce the construction cost.2007,1(1): 36-37 收稿日期：2006-2-19分类号：TE973.92作者简介：李加平（1974- ），男，湖北仙桃人，工程师，1998 年毕业于中国石油大学（东营），现从事管道工程技术管理工作。
