Construction method for rapidly replacing arch bridge tie bars in situ
The invention discloses a construction method for rapidly replacing arch bridge tie bars in situ. By means of the method, when the service life of existing arch tie bars in service is ended, the original arch bridge tie bars are rapidly replaced; in the replacement process, temporary tie bars are pulled on the two sides symmetrically and simultaneously, the two sides are replaced equivalently, and cables are symmetrically and gradually broken. The arch bridge tie bars are safely replaced, the original stress state is achieved, safety stock of the bridge tie bars is increased, and secondary replacement can be carried out; the service life of a bridge is prolonged, the engineering construction cost is saved, and the total economic benefits and social benefits are good.
