管道穿越大中型江河施工方案比选

On comparison and selection for construction schemes of pipelines crossing large and middle rivers

结合城市污水工程管道过河施工的实例,阐述了围堰施工、沉管施工、顶管施工三种不同的施工方法,对其施工工艺进行了分析对比,针对本工程的具体情况,最终确定采用顶管工艺施工,以满足施工要求。

Combining with the construction and example for the pipeline crossing rivers in urban sewage projects,the paper illustrates three different construction methods,that is,cofferdam construction,the sinking pipeline construction and pipe-jacking construction,analyzes and compares its construction craft,and adopts the pipe-jacking craft finally according to the factual circumstance for the project,so as to meet the engineering demands.
