Research on Lifting Techniques of Large Segments of Steel Box Girder of Chongqi Bridge

Abstract:

Techniques of lifting large segments of steel box girder by floating crane is used in construction of Chongqi Bridge. Considering the hydrological environment on the site, characteristics of steel box girders and performance parameters of floating crane, the selection of floating crane is carried out. To ensure hoisting work achieve function and safety, a new type of lifting device named Self-balance lifting device is designed, and the lifting-points design is optimized to make the reaction of all lifting-points of large segments equal. In the erection process of large segments, the security risk control is analyzed to ensure the steel box girders and lifting equipments safety.
