大渡河LST水电站泄洪洞初步设计

The Preliminary Design of Scouring Sluice about theHydropower Station of Yanjia RiverAbstract:Yanjia River Station is located in Baoji City,another area the village of HudianZhen on Weihe River in the main stream from baoji 46km,the Weihe River in Shanxi Province toenter the territory of the main stream of the cascade development planning in the first station.Yanjia River Station for a small (2)-type V and other projects,the main building for thefive buildings,is a pure hydro-electric power projects,primarily by retaining structures,sedimentstructures,water plants,such as buildings and power plant components.According determine theYanjia River Hydropower Station standard design flood for a return period of 10 years,thecorresponding peak discharge 2562m3/s,Project,factory calibration standard for 20-year floodreturn period,the corresponding peak flow for 2912 m3/s.Flushing sluice dam is located at the extreme left,close to the inlet connected with themountain,long 32m,for the rectangular hole gate are flat steel gate control,gate hole sand floorelevation is 730.00m,the operation of the gate running sand mainly based on water sedimentationroom conditions.The design of the buildings the main hub of the program carefully selected and detailed thanthe size of the design,and buildings designed by the security check to ensure the safe operation ofbuildingsKey words:Scouring sluice:Yanjia River:Hydropower Station
