西北某农村引水工程超高落差重力输水管道设计

Design of Ultrahigh Drop Gravity Water Conveyance Pipeline for a RuralWater Diversion Project in Northwest China

西北某农村引水工程,管道总长度5.7 km,总落差790 m。本文介绍了该输水管道的设计方法,包括管材选择、减压消能设计、排气阀和泄水阀布设等。本工程充分利用蓄水池与用水点的地形高差,实现重力供水,通过减压水池消除因高落差带来的输水安全问题,本设计可供类似工程项目借鉴和参考。

A rural water diversion project in Northwest China has a total pipeline length of 5.7 km and a total drop of 790 m.This paper introduces the design of the water conveyance pipeline,including the selection of pipe materials,the design of the decompression pool,the layout of exhaust valve and drain valve,etc.The project have fully used of the terrain elevation difference between the reservoir and the water intake spot to realize the gravitational water supply,and eliminate the water conveyance safety problems caused by the high drop through the decompression pool.The design of this project can provide references for similar projects.
