浅谈长距离重力输水工程的设计要点

The design points of the long-distance gravity water transfer project

随着哈密新型工业化的快速推进和经济社会的快速发展，水资源的需求矛盾日益突出，再生水的利用、长距离的输水都是解决水资源供需矛盾的有效办法。着重从输水管道管材的选择、管材工作压力的确定、钢管壁厚的确定、管道沟槽设计以及管线主要建筑物设计等方面，论述长距离重力输水工程的设计要点，可为类似工程提供一些经验和参考。

With the rapid development of the rapid advance of Hami new industrialization and economic society, the demand of water resource is becoming increasingly prominent, water use, recycled water long distances are effective ways to solve the contradiction of waterresources supply and demand. This article introduces the application of reclaimed water in the city in industrial water,mainly from the choice of pipe water pipe line, pipe work pressure determination, determination, thick steel pipe wall pipe trench design and main buildingpipeline design, discusses the key points of design of gravity water engineering of long distance,which can provide some experience and reference for the similar projects.
