Wedge-shaped Pushing Device for Bridge and Construction Method Thereof

摘要

A wedge-shaped pushing device for bridge and construction method thereof includes a base, a lifter and a pushing mechanism. The top of the base has a platform with a wedge-shaped block; the wedge-shaped block has a top side formed into an upper slope; the top of the lifter has a pad; the pushing mechanism has an upper wedge-shaped seat, hydraulic cylinders and a support seat; the upper wedge-shaped seat has top with a cushion and a bottom formed into a lower slope; the hydraulic cylinder has a piston rod; the support seat has a top fixed and combined with the hydraulic cylinder by a pivot. By the wedge-shaped pushing device, the box girder can be displaced and pushed to achieve the effects of lowering the construction cost, facilitating the installation, and improving the stability and safety of the displacement and pushing of the box girder.
