| 摘 要： | 为了解决高地下水位段由于地表承载力差,采用传统的沟上组焊吊装下沟的施工方法难度较大的问题。笔者结合沙漠段沉管下沟的方法在工程中的应用,在高地下水位段采用单侧沉管下沟的施工工艺。工程实践结果表明,该工艺成功解决了高地下水位段小口径长输管道施工面临的困难,极大地提高工程进度的同时保证了施工安全且减少了项目成本,可为同类地区的管道施工提供借鉴。

| Abstract: | In order to solve the problems of the lowering-in the small caliber pipeline at high groundwater level, the construction technique of pipeline-settled ditching on one side is applied in these regions with reference to using the technique in the desert area. The Engineering practice indicates that this technique has successfully solved the problem of the lowering-in of the small caliber pipeline at high groundwater level. The project progress is speeded up with low cost and becomes much safer. It is suitable for application in similar projects. |
