Concrete base parting structure

The utility model discloses a hydraulic and hydroelectric engineering structure, especially a concrete base parting structure. The utility model provides a concrete base parting structure of lowering the temperature stress, build the basement rock body including concrete base and arch dam, the one end setting of concrete base is on the basement rock body is built to the arch dam, and the base face is built for the arch dam to the other end, still include concrete base parting structure, concrete base parting structure falls into two parts with the concrete base, and concrete base parting structure's seam face is the skew surface. Great this parting of the concrete base adoption structure of volume can reduce concrete base temperature stress after carrying out the parting, reduces base concrete cracking risk, solves the not enough problem of the great construction machinery of base concrete placement storehouse face construction ability. After carrying out joint grouting to the base parting, the concrete base forms overall structure the most at last, is favorable to the the stress of base.
