Steel truss girder suspension bridge deck slab deviation-rectifying, resetting and pushing construction system and method
The invention discloses a steel truss girder suspension bridge deck slab deviation-rectifying, resetting and pushing construction system and method. The system comprises a constraining and limiting device and a resetting and displacement measuring device. The restraining and limiting device comprises a lower end plate, an upper end plate and a supporting inclined rod. The lower end plate is welded and connected to a steel truss girder beam upper chord member of a steel truss girder suspension bridge. The upper end plate is welded and connected to a bridge deck slab longitudinal beam of the steel truss girder suspension bridge. The upper end and the lower end of the supporting inclined rod are connected with the upper end plate and the lower end plate respectively. The invention further discloses the construction method for conducting deviation-rectifying, resetting and pushing through the steel truss girder suspension bridge deck slab deviation-rectifying, resetting and pushing construction system. By means of the system and method, in the bridge deck slab deviation-rectifying, resetting and pushing process, the bridge surface operation traffic state does not need to be limited, no pushing counterforce support needs to be arranged, and no adverse effects can be caused to stress of a bridge pier and abutment structure.
