多功能自动调节堰井的研究与应用

Studies on multi-function automatic-regulated weir well and its application

针对有压重力输水工程采用调节阀存在的问题,提出了多功能自动调节堰井这一新型控制性建筑物,介绍了多功能自动调节堰井的结构形式、特点、性能以及在南水北调中线天津干线工程的应用情况。实践证明,多功能自动调节堰井能够实现水头的自动调节,且运行控制简单。

Considering problems with pressured gravity water conveyance structures with regulating valve, studies have been made on new types of control structures namely multi-function automatic-regulated weir wells.Introductions are made mainly on structure type, features and performance of weir well and its application to Tianjin Mainline Scheme of Middle Route of South-to-North Water Diversion Project. It is proved to be usable for automatic regulation of water head and can be easily controlled.
