| Abstract: | Concrete double-curvature arch dam is designed for Yangfanggou hydropower station.The dam is with three middle outlets and four surface outlets.The corbel structure is arranged under the orifice.Through technology on formwork construction for precast concrete of the corbel structure,the construction period is saved,the project quality is guaranteed,and the safety risk is reduced,which lays a solid foundation for earlier generation.This paper introduces the above construction technology in detail,including design,processing and installation of precast concrete formwork,concrete pouring method and related control points,which can be referenced for other similar projects. |
