Method for Reinforcing Earthquake-Resistant of Bridge Pier

摘要

The present invention provides a bridge seismic reinforcement method for bridges to improve the concrete bondability and seismic performance by using a spiral reinforcement for the bridge reinforcement of the existing bridge to be bound to the structure of the existing bridge. To this end, the present invention is a method for performing a seismic reinforcement for the existing bridge of the bridge, proceeding the trench to the foundation portion of the existing bridge, performing the chipping of the chipping and chipping of the surface of the bridge, and the existing bridge Vertically fixing a plurality of vertical reinforcement stiffeners at regular intervals along a circumference of the pier, spaced apart from each other in a spiral shape from an upper surface of the pier foundation along the existing piers and the plurality of vertical reinforcement stiffeners; Performing a spiral-shaped reinforcement process of winding up and winding up a spiral reinforcing material for spiral winding; After pouring a certain period of time, When the molding is completed, characterized in that it comprises the step of removing the formwork.
