重庆李渡长江大桥主梁采用牵索挂篮悬浇施工,于超高度、大体积、大吨位的挂篮吊装属是一个难题;对该挂篮吊装进行了多种方案的比选论证,确定采用对该工程最为有利的简易连续爬升千斤顶的提吊工艺方案,与其它吊装方式相比,具有受力明确、施工简便、作业安全、成本低,对超高度及施工环境恶劣的高塔梁具有适应能力强,工期易保证、施工组织简便等特点。 The main girder of LiDu Yangtze River Bridge in Chongqing is suspended by cantilever construction with hanging ropes. It is a difficult problem to hoist the hoisting cranes in the ultra-high-altitude, large-volume and large-tonnage areas. Compared with other hoisting methods, the hoisting technology scheme of simple continuous climbing jack which is most beneficial to the project has the advantages of definite force, simple construction, safe operation and low cost, and adapts to the high-altitude high-altitude beam with super-high-altitude and poor construction environment Strong ability, easy to ensure the construction period, the construction organization is simple and so on.
