Abstract: [Introduction] There are a lot of problems such as sediment deposition in mountainous rivers to endanger the safety of water intake. We must adopt safe and effective water extraction installations to ensure the safe operation of power plants. Although existing water abstraction technology has reduced the harm to a certain extent, various problems still exist. [Method] This article analyzed some of the problems that existing in water extraction installations, through the optimization of layout, reducing the pump floor elevation, combining the pier and structures and flushing sluice lifting equipment through the pump room indoor and other measures to eliminate the problem of existing water extraction installations. [Result] A new water extraction installations is put forward, that can effcetively increase the pump suction depth, optimize flow pattern, facilitate equipment maintenance to further improve the safety of water intake to ensure the safe operation of power plants. [Conclusion] This water extraction installations can be used in the mountainous river intake project to bring good economic benefit.
