Project name: Hebei Qianxi Pumped Storage Power Station Lower Reservoir Project (QX/C3)
Project overview: Hebei Qianxi Pumped Storage Power Station is located in Luanyang Town and Shangying Town, Qianxi County, Tangshan City, Hebei Province, about 116 km away from Tangshan City and about 177 km away from Beijing. The installed capacity of the power station is 1000 MW. The key project of the power station is mainly composed of the upper reservoir, the lower reservoir, the water conveyance system, the underground powerhouse and the switch station, the open channel of the river, the make-up pump station and other buildings. The upper reservoir is located at the head of the natural gully, and the terrain is relatively open. The reservoir basin is formed by excavation in the reservoir and damming in the main gully. The lower reservoir is located in the Changhe River valley. Due to the large sediment content of the river flow, in order to avoid the impact of the sediment flow on the unit, the downstream dam and the upstream sediment dam are built at the turning point of the Jinlongkou Village to Chaoyu Gully downstream of the Changhe River to form a special reservoir. The open channel of the river course is set up by cutting off the bend and straightening, and the flood and sediment of the long river do not enter the reservoir.
Construction site: Qianxi County, Tangshan City, Hebei Province.
Bidding scope: Hebei Qianxi Pumped Storage Power Station Lower Reservoir Project (QX/C3), including but not limited to lower reservoir civil works, lower reservoir inlet/outlet, water replenishment works, mechanical and electrical equipment installation, metal structure equipment installation, ground buildings and decoration works, Y9 water replenishment project road (permanent road), Initial impoundment and construction auxiliary facilities.
