Method for replacing bridge support
The invention discloses a method for replacing a bridge support. A jack (1) is arranged between a bridge and a bridge pier, the upper portion of a working rod (18) is in threaded fit with a locking ring (19), and the locking ring (19) moves up and down along with the working rod (18). The locking ring (19) is rotated so as to move downwardly until the locking ring (19) is in contact with a supporting frame (20) of the jack (1), then the working rod is locked, and the bridge support is replaced or repaired at this moment. The locking ring (19) is rotated so as to move upwardly, the working rod (18) is unlocked, the bridge falls back as the jack (1) falls back, then the locking ring (19) is rotated again so as to move downwardly, the working rod (18) is locked, and the locked jack (1) replaces the bridge support, so that the normal traffic cannot be influenced. According to the invention, a sliding function is provided for the bridge, so that damage on the bridge due to uneven jacking force, temperature, and concrete contraction and creep can be prevented, and the bridge can be better projected.
