南水北调东线工程金湖站厂房布置研究

Study on the Plant Layout of Jinhu Pumping Station of the Eastern Route Project of the South-to-North Water Diversion

金湖站位于南水北调东线长江至洪泽湖段输水线上,其主要任务是供水、排涝和防洪,设计流量150m^3/s,安装灯泡贯流式机组5台套。该站采用堤身式布置型式,具有挡洪水位高,机组安装位置低,单机设计流量大,供排水扬程悬殊,周边地势低洼等特点。为协调好站区内外部环境,提供良好的运行管理条件,现从金湖站工程的具体条件出发,提出了四个厂房布置方案进行研究,经技术、经济比较,选择了地下式厂房的布置方案。

Jinhu pumping station is located on the water transfer line from the Yangtze River to Hongze Lake of Eastern Route Project of South-to-North Water Diversion. Its main tasks are water supply, water discharge and flood control. There are 5 bulb tubular pumping sets, and the design discharge of Jinhu pumping is 150 m^3/s The pumping station is of levee body type layout in river channel with the characters of high flood water level, low installing elevation of pump, large design discharge of unit pump, wide gap head between water supply and discharge, and low elevation of surrounding areas In order to ecordinate a harmonious work and management conditions in the pumping station, four plant layout schemes are discussed and the underground plant scheme is proposed by technical and economic comparison on practical conditions of Jinhu pumping station.
