Concrete pedestal parting structure and construction method

The invention discloses a hydraulic and hydroelectric engineering structure, and particularly relates to a concrete pedestal parting structure. The concrete pedestal parting structure which can reduce temperature stress comprises a concrete pedestal and an arch dam foundation rock body, wherein one end of the concrete pedestal is arranged on the arch dam foundation rock body, and the other end of the concrete pedestal is an arch dam foundation surface. The concrete pedestal parting structure further comprises a concrete pedestal parting structure body which divides the concrete pedestal into two parts, and the seam surface of the concrete pedestal parting structure body is an inclined curved surface. After the concrete pedestal with a large size is parted through the concrete pedestal parting structure, the temperature stress of the concrete pedestal can be reduced, the cracking risk of concrete of the pedestal is lowered, and the problem of poor construction capacity of a construction machine when the concrete pouring bin surface of the pedestal is large is solved. After the parting seam of the pedestal is subjected to joint grouting, the concrete pedestal finally forms an integrated structure, and the overall stress of the pedestal is facilitated.
