- 摘要:
- 以甬—沪—宁原油管道工程江苏宜兴段溪梢北河穿越工程为例，介绍了一种河流穿越的施工方法——顶管穿越法。从工程概况、施工准备、施工流程和技术措施方面进行了详细的阐述。重点介绍了工作井、接收井的制作、就位，顶管设备的顶进和纠偏，穿越主管道采取的主要技术措施以及顶管穿越河流时应注意的几个问题。
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.2006,5(5): 33-36 收稿日期：2005-12-22分类号：TE973.4作者简介：刘乃银（1973- ），男，土家族，湖南常德人，工程师，1994 年毕业于大庆石油学院化机专业，一直从事长输管道和定向钻穿越施工技术质量管理工作。
