福州鼓台区陆庄河河道补水设计中一体化泵闸的应用

The Application of Integrated Pump Gate in the Water Supplement Design of Luzhuang River in Gutai District of Fuzhou

我国南方某城市内河河网相互连通,部分河道纵坡极缓,水动力严重不足,需要修建补水调水的水利设施,以提升河道流量,实现活水亲水的景观环境。一体化泵闸作为一种新型河道水利设施,主要应用于中低扬程的防洪排涝和河道补水等水利工程。文章以福州市鼓台区陆庄河一体化泵闸工程为案例,阐述了一体化泵闸应用于河道补水的设计思路,对设计中关键问题和相应解决思路进行了剖析;并结合InfoWorks ICM软件构建河网水动力模型,模拟得出了枯水期和汛期一体化泵闸运行调度方案,以期为项目建成后的运行提供参考。

The inland river network of a city in southern China is interconnected.The longitudinal slope of some rivers is very slow and the hydrodynamic force is seriously insufficient.It is necessary to build water conservancy facilities for water supplement and diversion to improve the river flow and realize the landscape environment with living and hydrophilic water.As a new type of river water conservancy facilities,the integrated pump gate is mainly used in flood control and drainage,river water supplement and other water conservancy projects with medium and low lift.Taking Luzhuang River integrated pump gate project in Gutai District of Fuzhou City as an example,this paper expounds the design idea of integrated pump gate applied to river water supplement,and analyzes the key problems and corresponding solutions in the design.Combined with InfoWorks ICM software,the hydrodynamic model of river network is constructed,and the operation scheduling scheme of integrated pump gate in dry season and flood season is obtained by simulation,so as to provide reference for the operation of the project after completion.
