THE BRIDGE UPPER PART STRUCTURE LIFT METHOD FOR WHICH A BRIDGE UPPER PART STRUCTURE DISPLACED CONTROL SYSTEM AND THIS WERE USED

摘要

The present invention is to restrain the bridge superstructure in the stable state by restraining the longitudinal direction of the bridge superstructure in which the displacement control device is installed when the displacement of the bridge superstructure can occur during the bridge superstructure lift It is an object of the present invention to provide a control device and a method of raising a bridge superstructure using the same. Bridge superstructure displacement control apparatus according to the present invention for achieving the above object is a plurality of support members that are fixed to the chemical anchor on the connecting slab; A fixing member fixed to the upper portion of the bridge upper structure that is pulled between the supporting members by a chemical anchor; The hydraulic member is installed between the support member and the hydraulic jack is installed on the upper surface of the lower structure to raise the bridge upper structure in a state in close contact with the side at the same time. In addition, the bridge upper structure lifting method using the bridge upper structure displacement control apparatus according to the present invention for achieving the above object is fixed to the support member on the upper surface of the connecting slab fixed with a chemical anchor, the upper bridge is lifted between the support member The fixing member fixed by the chemical anchor is inserted into the upper part of the structure, and close to the side and at the same time, the hydraulic jack is installed on the upper surface of the lower structure to configure the bridge upper structure displacement control device, and then the hydraulic jack is applied to the hydraulic jack to raise the bridge upper structure. It is characterized by.
