Quality Inspection and Safety Evaluation of Concrete for Existing Reservoir Dam as Lower Reservoir of Pumped Storage Power Station
In order to evaluate the safety of the existing reservoir dam as the lower reservoir of pumped storage power station,the concrete quality of the dam of Hongyan Hydropower Station by crack detection,corrosion leakage detection,water erosion detection,concrete rebound and carbonation depth detection,steel protection layer thickness detection,hole imaging and concrete drilling core performance detection.The results show that the concrete on the dam surface of Hongyan Hydropower Station is affected by carbonization and there is aging phenomenon;No obvious cracks were found on the upstream surface,downstream surface and dam crest of the dam,and the dam body is in good operation;It is feasible to use Hongyan Hydropower Station as the lower reservoir of Guiyang Pumped Storage Power Station.The research results can provide reference for other pumped storage power stations to use existing reservoirs.
