摘要

PURPOSE: A temporary bent for pulling up top structure and a method for forming the same, and a process for pulling the top structure with the temporary bent are provided to conveniently replace shoe of a bridge by mounting a hydraulic jack and easily supporting H-beam. CONSTITUTION: The temporary bent(4) comprises a lower cross H-beam(41) consisting of a pair of horizontal components; a vertical H-beam(43) consisting of a pair of vertical components at both ends of the beam(41); an upper H-beam(42) having one end secured by anchor at a pier and placed on top side of the vertical H-beam(43); a horizontal beam(3) placed above the cross H-beam(42) with a hydraulic jack(2); and a fastening beam mounted on a part of the vertical H-beam and having one end secured by anchor at the pier. The pier(5) is closely coupled with the temporary bent(4) onto a concrete foundation(6') for drawing up a top structure(1) of a bridge in order to replace a shoe of the bridge.
