一种轨道交通钢结构桥梁
By incorporating guide grooves and anti-slip springs inside the sleepers, along with structures such as cross-shaped limit plates, threaded columns, and adjusting columns, the adjustable support capacity of the bridge is enhanced. This solves the problem of deflection and torsional deformation that occurs in traditional rail transit steel structure bridges under vehicle loads and environmental factors, enabling real-time monitoring and adjustment of the bridge and ensuring its stability and traffic safety.
