The water intake of the power station of Jiayan Hydro-complex Project covers a large range.To meet the water quality requirement,layered water intake was schemed.Two water intaking schemes of multi-layer water in⁃taking and stoplog gate were compared by considering the construction conditions.The multi-layer water intaking scheme was adopted.The layout,type selection and design ideas of the metal structure of the water intake of the hy⁃dropower station behind the dam are introduced.The demonstration showed that the metal structure of the project is compact in layout,reasonable in structure,economic in engineering quantity and easy in equipment operation and maintenance.The design can be used as reference for similar projects.
