Upper storage reservoir basin seepage preventing method
The invention discloses an upper storage reservoir basin seepage preventing method. Rock mass water-permeable rate detection is performed according to the exposure situation of an upper storage reservoir basin bed rock, and rock mass surface closing and seepage preventing treatment is conducted in a region with rock mass water-permeable rate q smaller than 3 Lu (lugeon) by adopting a pneumatically placed concrete layer. Reinforced concrete slabs are adopted to perform surface closing seepage preventing treatment in an intensive joint belt rock mass region with rock mass water-permeable rate q greater than 3 Lu (lugeon) and a fracture development position rock mass region. A non-fine concrete water drainage pad layer is arranged at the lower portion of the reinforced concrete slabs, multiple water-permeable pipes are arranged at the lower portion of the non-fine concrete water drainage pad layer so as to reduce floating-supporting force of the reinforced concrete slabs and ensure engineering safety. According to different permeability characteristics of an upper storage reservoir rock mass, the reinforced concrete slabs and the pneumatically placed concrete layer are combined for seepage preventing, and the purposes of saving investment, facilitating construction and saving water sources are achieved while the seepage preventing requirements of rocks different in permeability are met.
