本工程是跨流域引水,以灌溉为主结合发电的中型水利工程。全部工程包括卡房水库、电站、长坝、罗坝两处低坝引水渠首、总干渠、东、西干渠及灌区工程。总干渠设计最大引水量10.0米~3/秒。工程建成后可扩灌10.8万亩,保灌5.0万亩。上游蓄水总库容3570万立方米。养鱼水面0.15万亩。坝后电站装机4000千瓦。一期工程1975年冬开工,1984年建成双渠首低坝引水灌溉系统,扩灌5.0万亩,保灌2.0万亩。计明渠砌护34.95公里,隧道33座15.04公里,明涵5.53公里,以及其他各种建筑物608座。总干渠施工期为5年,整治滑塌又延续了4年。直到1984年正常通水。
This project is a medium-sized water conservancy project that takes charge of water diversion across the river basin and combines power generation mainly with irrigation. All projects include the Karst reservoirs, power plants, dam, Luo dam two low dam diversion canals, the main canal, east and west trunk canals and irrigation works. The total design of the main canal water diversion 10.0 m ~ 3 / sec. After the completion of the project can be expanded 10.8 acres, Paul irrigation 5.0 million mu. The total storage capacity of upstream storage 35.7 million cubic meters. Fish water surface 150000 mus. Dam power station installed 4000 kilowatts. The first phase of the project started in the winter of 1975, and in 1984, the first low-water diversion irrigation system was built in Shuang Channel. It expanded and irrigated 50,000 mu and guaranteed 200,000 mu. Counting Mianqun 34.95 km, 33 tunnels 15.04 km, Ming Han 5.53 km, and a variety of other buildings 608. The main canal construction period of 5 years, renovation and collapse lasted for 4 years. Until 1984 the normal water.
