彭水县城高扬程取水工程设计

Design of High Lift Water Intake for Pengshui County

三峡库区的高扬程长距离取水工程数量较多,以重庆市彭水县城取水泵站为例,在对取水点处水文、地质、地形等资料进行分析调研的基础上,经过技术经济方案比较,选择了安全可靠、运行管理方便的固定干井取水泵站方案。系统介绍了水源、取水口、取水泵站及水锤防护的设计参数及考虑因素。实际运行结果表明:固定干井取水泵站运行可靠,作业环境好;水锤防护措施可有效保障泵站及输水管安全。

There are many high lift and long distance water intake projects in the three gorges region. Taking the Pengshui County project as example, a general investigation was done on the hydrological, topographic and geological at the water intake site. On the basis of investigation and techno-economic comparisons for operation reliability and convenience, a design of fixed dry well water intake pump station was proposed. The design parameters and characteristics of water source, water intake, pumping station and prevention of water hammer are presented. The running results show that the operation of fixed dry well water intake pump station is reliable, and the working environment of the station is safe. The prevention measures of water hammer ensure that the pump station and delivery pipe are safe.
