| Abstrait: |
A certain bridge adopts the green design of "one span across the river", and the installation of 21 pieces of steel box girder on the south span is limited by geographical conditions, tower limb width and construction period. Innovatively developed a dedicated skid scooter, the steel box girder successfully crosses the orbit change position with the help of the windlass，move laterally to the tower area，replace the longitudinal skid scooter，move to the design bridge. In the steel beam positioning link, firstly, set bearing pre-offsetting on pier top support to circumvent the influence of steel box girder welding, shrinkage creep deformation and closure temperature difference on the displacement of beam length. After the bridge is completed, the feasibility and reliability of the research method are verified by elevation measurement, static load test and implementation process. |
