南水北调供水管线穿越道路设计方案

Design Scheme of Road Crossing in South-to-North Water Diversion Project

南水北调受水区供水配套工程沿线穿越、邻接工程众多。文章以南水北调中线总干渠供水管线穿越、邻接南阳市原西环路为例,通过穿越方案比较,确定供水管线穿越道路采用钢管外设钢筋混凝土套管、与污水管道交叉采用下沉供水管线设计方案,并对施工中主要问题提出了处理方法,保障了供水管线工程安全及供水安全,对供水管线穿越道路及污水管道的设计具有借鉴作用。

There are many supporting projects of water supply in the water receiving area of the South-to-North Water Diversion project. Taking the water supply pipeline crossing the main canal of the middle line of the South-to-North Water Diversion Project and adjacent to the former West Ring Road of Nanyang as an example, the design scheme of the water supply pipeline crossing the road with steel pipe and reinforced concrete casing and the design scheme of the water supply pipeline crossing the sewage pipeline with the sinking water supply pipeline are determined by comparing the crossing methods. In addition, the main problems in the construction are dealt with to ensure the construction safety of the water supply pipeline engineering and water supply safety, which can be used for reference in the design of water supply pipeline crossing roads and sewage pipelines..
