四川省东部山区某长距离超高扬程输水工程设计总结

Design Summary of a Long-distance Ultra-high-lift Water Transmission Project in the Eastern Mountain Area of Sichuan Province

四川省东部山区某长距离超高扬程输水工程,既有超高压力流输水管道的特点,又有超高重力流输水管道的特点,且各供水点的地形高差较大,增加了水锤防护的设计难度。为确保供水安全可靠,本工程进行水锤模拟分析,并采取一系列水锤防护措施,针对本工程试运行中存在的问题进行分析总结,可为其他工程的建设提供借鉴参考。

A long-distance ultra-high-lift water conveyance project in the eastern mountainous area of Sichuan Province processes the characteristics of both ultra-high-pressure power flow water conveyance pipeline and ultra-high-gravity flow water conveyance pipeline.Moreover,the significant elevation difference at each water supply point increase the difficulty in water hammer protection design.To ensure the safety and reliability of water supply,this project conducted water hammer simulation analysis and adopted a series of water hammer protection measures.In addition,the problems existing in the trial operation of this project are analyzed and summarized to provide reference for the construction of other projects.
