The prefabricated box girder body is attractive, and the prefabrication is convenient. Due to the longitudinal and transverse slope relation of the roadbed, when the gradient is greater than 2%, the bottom of the precast box girder needs to be provided with wedge blocks for leveling so as to meet the level of the support. The wedge is influenced by the longitudinal and transverse slopes of the roadbed and the elevation of the bridge, and the height is often adjusted differently, so that the requirement on the activity characteristics of the pedestal is high.

If the treatment is improper, the support and the beam bottom embedded steel plate are supported unevenly and are free. Under the long-term action of the dynamic load of the vehicle, the support is easy to damage and even fall off, and hidden quality hazards are buried for the safety operation of the bridge. The existing pedestal is generally flat bottom, the transverse slope of the support cannot be adjusted, the support surface and the concrete surface are not tightly attached when the girder is erected on site, potential safety hazards are generated, and the construction precision of the wedge block is limited to the fine and standardized construction of bridge engineering.
