输配水管道设计体会

Experience of water-supply pipeline design

结合工程实例 ,分析了城市输配水管道设计中遇到的一些问题 ,介绍了几种常用管材的性能和使用情况 ,论述了不同地质条件下 ,管道基础处理的不同方法 ,并对管道附属设施的阀门、伸缩门、排气阀、泄水阀及支墩的选型及使用情况进行了说明 ,指出在管位的确定上要考虑多方面因素 ,进行技术性和经济性的比较。

Combined with actual example the problems accounting in the design of city water supply pipeline are analyzed. The performances of several common tubes and their operation situation are introduced. The different methods in foundation treatment for different geological conditions are discussed. And some concrete specification are given such as valves, expansion loop, air outlet valve, wash out valve, the type selection of abutments and so on. At last author point out that several aspects' factors should be considered and the comparison in technology and economy should be processed in pipe position's determination.
