摘要

PURPOSE: A method for dismantling the deck of a bridge using a lifting jack integrated in a pier is provided to dismantle the deck of a bridge without separate equipment, such as a crane, installed under the bridge. CONSTITUTION: A method for dismantling the deck(20) of a bridge using a lifting jack integrated in a pier(10) is as follows. A part of the deck around the pier is cut and dismantled in order to set a temporary facility. A temporary facility is installed on adjacent piers and a lifting jack(200) is installed on a jack base of the temporary facility. A lifting beam(300) is installed on the ground and connected to the lifting jack with a wire. The lifting beam is raised to the lower part of the bridge deck. The bridge deck is cut in order not to interfere with the piers. The lifting beam in which the bridge deck is placed is lowered.
