BW

The Shuangjiangkou Dam, also written as Shuang Jiang Kou, one under construction dam on the Dadu He is a rock -fill dam as a shut-off in Sichuan Province of the People's Republic of China. When it is completed, the 312 m high dam is the highest of the earth will be. Preparatory construction work began in 2008 and it is expected that they are completed in 2012. Until April 2011, over 200 million cubic meters of material were excavated from the pit. The total construction period will last 10 years.

Building

The shut-off, when it is completed, be a 312 m ( at the maximum of 314 m above the foundation level ) high and 648.66 m long rockfill dam with a relatively impermeable core. The width of the dam crest is 16 m, its height 2510 m above sea level. The dam will have a building volume of 44 million cubic meters. The catchment area is 39,330 km ² and the work space is 3135 million cubic meters in size, of which 2151 million m³ are controllable usable space. The normal water level will fluctuate between 2500 m and 2420 m. At high tide it can rise up to 2504 m. The completed hydropower plant gets four 500 MW Francis turbines and generators for a total installed capacity of 2,000 MW. The guaranteed minimum benefit should be 503 MW. At 4064 hours running time per year 8128 GWh can be produced. The power plant is designed for a flow of 1090 m³ / s and the mean hydraulic height is 226.4 m.
