1987年12月15日8时53分位于湖北省清江上的隔河岩水电站截流成功。隔河岩水电站是在清江上修建的第一个大型水电工程,电站装机容量120万kW,最大坝高151m,总库容34亿m~3,控制流域面积14400km~2。整个枢纽工程由大坝、电厂、升船机等建筑物组成。主要工程量为混凝土浇筑325万m~3,土石方开挖614万m~3,金属结构安装2.1万吨。全部工程由水利电力部和湖北省集资,并由湖北省负责按审定的概算采取招标承包方式进行兴建。隔河岩水电站施工导流系采取全河一次断流,隧洞导流的方式。导流隧洞全长695m,设计导流流
At 1553 hours on December 15, 1987, the Geheyan Hydropower Station on the Qingjiang River in Hubei Province was successfully closed. Geheyan Hydropower Station is the first large-scale hydropower project built on Qingjiang River with an installed capacity of 1.2 million kW and a maximum dam height of 151m with a total storage capacity of 3.4 billion m 3 and a control basin area of 14,400km 2. The entire hub project by the dam, power plants, ship lift and other buildings. The main volume of construction for the concrete pouring 3.25 million m ~ 3, earthwork excavation 6140000 m ~ 3, the installation of 21,000 tons of metal structures. All projects are financed by the Ministry of Water Resources and Electric Power and Hubei Province, and Hubei Province is responsible for the construction according to the approved budget estimates by means of bidding and contracting. Geheyan hydropower station construction diversion system to take a river cut off, tunnel diversion way. The diversion tunnel is 695m in length and is designed with diversion flow
