- 摘要:
- 在管道建设中经常遇到河流、山谷等自然障碍物或人工构筑物,给管道建设工程带来了一定的复杂性和施工难度。对于河流较深无法进行管道穿越的工程,一般采用跨越形式,而大跨度跨越工程多数采用悬索结构形式。该结构形式较复杂,施工难度大。文章结合长庆油田靖咸输油管道工程中的清峪河跨越施工实例,详细介绍了大型悬索管道跨越施工方法。包括塔架基础施工以及塔架、悬索、工作索的预制安装和管道的预制、发送安装。
During the pipeline construction, the river, valley etc. nature obstructers manmade buildings were often encountered, which brings a lot of complexities difficulties for pipeline construction. The crossover is a usual pipeline crossing form for some deep rivers those are not able to use a boring-thrust construction method. Among the large span pipeline crossing, the most projects use suspension cable structure form. This structure form is more complicated the construction is more difficult. Combining with the pipeline over-crossing construction in Qingyu River, the paper details the crossover construction method of large size suspension pipeline in Jingbian -Xianyang oil pipeline project, Changqing oilfield.2002,6(6): 16-18,3 收稿日期：2002-8-14分类号：TE973作者简介：孙树山,高级工程师.1982年毕业于沈阳工业大学焊接工艺与设备专业,现任辽河石油勘探局油建一公司总工程师,从事工程技术质量管理工作.通讯地址:辽宁省盘锦市,邮编:124120
