滇池补水工程干河提水泵站系统总体布置简述

Introduction to general layout of Ganhe River Pumping Station system for Niulan River-Dianchi Lake Water Supplement Project

牛栏江-滇池补水工程主要由德泽水库枢纽工程、干河泵站提水工程及输水线路工程组成。水库枢纽布设在牛栏江干流上,在距大坝18 km的库区建设最大提水扬程233.3 m的干河泵站,再利用盘龙江河道输水到滇池。干河地下提水泵站是工程建设的难点,它布置在埋深150 m的地下洞室中,工程建筑物地下洞室群结构复杂,施工难度大,且运行期位于水库水位以下70多米。对泵站进水系统、提水系统和出水系统建筑物的组成、布置以及设备的布置情况进行了简要介绍。提水泵站已于2013年底正式投入运行,且各系统联动运行正常,总体效果良好。

Niulan River - Dianchi Lake Water Supplement Project is composed of Deze Reservoir Project, Ganhe River Pumping Station and water diversion line. The Ganhe River Pumping Station with maximum lift head of 233.3 m is built 18 km away from the dam in the reservoir area, which delivers water to the Dianchi Lake through the Panlong River channel. The Ganhe River Underground Pumping Station with buried depth of 150 m was a challenge in the construction as it is characterized as complex structures of underground chambers, difficult construction and more than 70 m below the reservoir level during operating period. The formation and arrangement of inflow, pumping system and outflow system structures of the pumping station, as well as the arrangement of equipment were briefly introduced. The pumping station was put into operation with satisfactory state at the end of 2013.
