Large-span bridging gantry crane and construction method thereof
The invention discloses a road and bridge construction technology. A large-span bridge gantry crane comprises temporary track bridges arranged on the two sides of an existing river-crossing bridge, sliding tracks are arranged on the temporary track bridges, the large-span bridge gantry crane further comprises a gantry crane portal frame arranged above the existing river-crossing bridge, supportinglegs are connected to the lower portion of the gantry crane portal frame, and sliding groove bases corresponding to the sliding tracks are arranged at the lower ends of the supporting legs. The large-span bridge gantry crane ingeniously starts from the construction angle, gantry crane equipment is arranged above an existing river-crossing bridge, hoisting operation is easily achieved, precise hoisting equipment is provided for widening or dismantling or maintaining construction of the existing river-crossing bridge, and the wading construction precision of the equipment is guaranteed.
本发明公开了一种路桥施工技术。本发明的大跨度架桥龙门吊，包括设置在既有跨江大桥两侧的临时轨道桥，在所述临时轨道桥上设有滑动轨道，还包括设置在既有跨江大桥上方的龙门吊门架，在龙门吊门架的下方连有支腿，所述支腿下端与滑动轨道对应设有滑槽座。该大跨度架桥龙门吊巧妙地从施工角度出发，实现在既有跨江大桥上方配置龙门吊设备，轻松实现吊装操作，为既有跨江大桥的扩宽、拆除或维护施工提供精准吊装设备，保证设备涉水施工精度。
