Lifting and transportation scheme for steel box girder of pedestrian landscape bridge
Section II Engineering Features and Technical Requirements I. The main bridge of the central axle bridge is a 105m long steel box girder bridge, which uses straight web steel box girders. The top width of the bridge deck is 5.5m, the beam height is 1.2m, and the bottom width is 2.5m; The bridge deck is set with a maximum longitudinal gradient of 3% and a two-way transverse gradient of 1%. 2、 Due to the river crossing, heavy single bridge, far lifting points, and difficult lifting operation, the lifting location is in the built scenic area, which will cause some damage to the landscape, trees, and river slope protection, and requires the strong cooperation of relevant departments. 3、 The weight of steel box girder is 215.4T. South bank: 0 # - 1 # span 2m, 1 # - 2 # span 28m, 2 # - 3 # span 30m. River crossing section: 3 # - 4 # span 30m. North bank: 4 # - foundation beam span 15m. 4CM expansion joint at the axis of 4 # pier. 4、 Installation height: 2-4.5m above the park floor for 1 #, 2 # and 3 # shafts. 4 # axis is 5m away from the riverbed.
