REMOVAL METHOD OF GIRDER REINFORCED-CONCRETE SUPERSTRUCTURE OF BRIDGE USING CABLE-SUPPORTED SYSTEM Russian patent published in 2014 - IPC E01D24/00 

FIELD: construction.

SUBSTANCE: invention relates to bridge construction, and namely to a bridge removal method and device. The removal method of a girder reinforced-concrete superstructure of a bridge using a cable-supported system allows removing the superstructure as quick as possible from its location and a possibility of removal of the superstructure onshore due to the fact that hydraulic jacks are installed under the lower flange for jacking; after that, channels are installed under the lower flange of girders; then, a metal traverse is installed; after that, the traverse is combined with channels; a pylon is installed on the traverse; stay cables are suspended and tightened; after that, supporting parts of girders are replaced with a moving device; the superstructure is removed together with the formed assembled structure onto receiving jigs arranged onshore, and the superstructure is disassembled. Channels for the lower flange of girders are installed in longitudinal direction. The traverse is installed along the whole superstructure of the bridge to be disassembled. The traverse and the channels are combined by means of vertical tie-rods with further welding to each other. The pylon is installed for example in the middle of the superstructure. As the moving device, rollers or fluoroplastic gaskets are used.

EFFECT: invention allows improving removal efficiency due to removal of the superstructure as quick as possible from its location place and possibility of its onshore disassembly.
