AI Technical Summary
Existing simply supported beam bridges suffer from problems such as transverse cracks at the bottom of the beams, insufficient structural stiffness, and insufficient load-bearing capacity when faced with increased traffic volume and heavy vehicles. Existing reinforcement methods cannot effectively improve the structural stiffness and load-bearing capacity of the bridges, and the construction operation is difficult.
A steel corrugated plate lining reinforcement structure is adopted. The steel corrugated plates are arranged in a ring along the longitudinal direction of the bridge and fixed to the concrete side walls. Self-leveling concrete is poured inside to form a ring space. It is then fixed to the original bridge main beam by shear studs, L-shaped rebars and steel mesh, which increases the cross-sectional reinforcement ratio and enhances the structural stiffness and load-bearing capacity.
It significantly improves the overall stiffness and load-bearing capacity of the bridge, inhibits the development of transverse cracks at the bottom of the beam, makes the main beam more uniformly stressed, and simplifies construction operations.
