A RAISING UNIT OF SUPERSTRUCTURE OF THE BRIDGE, APPARATUS FOR RAISING A SUPERSTRUCTURE OF THE BRIDGE, AND METHOD FOR SIMUTANEOUSLY RAISING THE SUPERSTRUCTURE OF THE BRIDGE USING THEREOF

摘要

A superstructure lifting apparatus of a bridge according to one embodiment of the present invention is provided to simultaneously lift the superstructure of a bridge by being disposed plurally in number between the super structure and the substructure of the bridge, and comprises: multiple superstructure lifting units disposed on the floor surface of the superstructure of the bridge and the upper side of the substructure of the bridge; a sensor unit which is disposed on the upper part of the substructure of the bridge and which senses the pressure applied from the superstructure of the bridge to the substructure of the bridge and the displacement of the superstructure of the bridge to the substructure of the bridge; and a control unit which is connected to the multiple superstructure lifting units and control the rate of fluid provided for the superstructure lifting units. It is desired that the multiple superstructure lifting units lift the superstructure continuously and simultaneously depending on the consideration of the displacement of the superstructure of the bridge and of the load applied to the superstructure of the bridge.
