Construction method of arched steel structure truss bridge

The invention discloses a construction method of an arched steel structure truss bridge, which comprises steps of prefabricating of multi-section steel structure bridge sections, preparing load-bearing cars in accordance with the curvature of the arch bottom surface of each section of the bridge section, setting up temporary bridges at the pre-selected construction site, laying a track on the bridge, towing the bridge sections in order of number from one end of the track to the other and then welding into one, dismantling all load-bearing cars and temporary bridges, and finishing the work. Byadopting the technical scheme of the construction method of arched steel structure truss bridge, the shape precision of the arched steel structure truss bridge is guaranteed, the labor intensity is reduced, the load-bearing car is easy to be processed and manufactured, and the construction technology is simplified without the operation of leveling and correcting during the setting up of the bridge.
