Rapid hoisting method for large-span steel bridge
The invention discloses a rapid hoisting method for a large-span steel bridge, and relates to the technical field of bridge construction. A steel bridge is constructed through segmented production in advance and then transported to a site, the steel bridge is rapidly hoisted after arriving at the site, during hoisting, segmented hoisting is conducted through multi-crane combined operation, and pier falling of the steel bridge is rapidly and accurately achieved. And after hoisting is completed, bridge supports are temporarily built at the lower ends of the steel bridges at the joints of the segmented parts, and after the steel bridges hoisted in the segmented manner are welded at the joints and are stable, the temporary bridge supports can be removed, and normal road traffic is recovered. The method is rapid and efficient, influence on road traffic can be neglected, and contradiction and pressure between bridge construction and road traffic are relieved.
本发明公开了一种大跨度钢桥快速吊装方法，涉及桥梁施工技术领域，通过提前分段生产构建好钢桥之后再运输至现场，到现场后快速进行钢桥吊装，吊装时通过多吊车联合作业分段吊装，快速准确的实现钢桥落墩，吊装完成后仅在分段部位的接合处钢桥下端临时搭建桥梁支撑，当分段吊装的钢桥在接合处焊接完成并稳定后，即可拆除除临时桥梁支撑，恢复正常的道路交通。本发明快速、高效、对道路交通造成的影响几可忽略不计，缓解了桥梁施工与道路交通之间的矛盾与压力。
