The invention discloses a method for reinforcing a cast-in-place framed flower
bed type anti-collision wall formwork of an urban overpass, wherein the method is used for the technical field of bridge construction. The method includes the following steps that an inside outer die, an outside outer die, an inner die and end dies are prefabricated; the inside outer die is installed, a top beam in the transverse bridge direction is arranged at the top of the inside outer die, a connecting rod is connected between the inner end of the top beam and a connecting seat on an inside beam body of the inside outer die, a
cantilever is formed at the outer end of the top beam and connected with the inner die, the outside outer die is installed, the top of the outside outer die is connected with the
cantilever, the bottom of the outside outer die is connected with the beam body, and the end dies are installed; the length of the connecting rod is adjusted to correct the perpendicularity of a formwork
system, a pull rod is tensioned and fastened between the inside outer die and the outside outer die after the elevation of the inside outer die, the elevation of the outside outer die and the elevation of the inner die are adjusted; and concrete is poured, and the formwork
system is detached after the concrete reaches the die detaching strength. By the adoption of the method, the
structural stress is clear, safety and reliability are achieved, reinforcing materials are saved, a construction period is short, operation is easy and convenient, the overall stability is high, and die
cracking is unlikely to happen.
