Abstract
An installation method of a bent cap for mutually restraining adjacent pier studs in a prefabricated and assembled bridge is provided. A bent cap mold base is configured in a form of a bent cap, which includes fixedly arranging limiting steel rings at two ends of a rectangular frame and vertically arranging steel bar sleeves in the limiting steel rings, hoisting the cap bent mold base on top portions of adjacent two prefabricated pier studs, such that pier stud pre-embedded steel bars protruding from the top portions of the two prefabricated pier studs are correspondingly inserted into the steel bar sleeves at two ends of the bent cap mold base one by one, and limiting the adjacent two prefabricated pier studs in the bent cap mold base.
