[0002] Steel structure bridges are bridges that use steel as the primary load-bearing material and are widely used in highways, railways, and urban transportation. Their main components, such as beams, trusses, and arches, are made of steel plates or steel sections. They have the characteristics of high strength, light weight, and good ductility. Steel structure bridges are fast to construct and can be prefabricated and assembled, making them suitable for large-span designs such as suspension bridges and cable-stayed bridges. The uniformity and plasticity of steel give them excellent seismic performance. When a steel structure bridge is used for a long time, it will be affected by factors such as vibration and deform. It needs to be reinforced and maintained regularly. However, the existing support blocks are usually used to support and reinforce the bottom of the bridge. The size of these support blocks is usually large, and special transportation tools are required to transport them to the vicinity of the bridge, which affects the reinforcement of the bottom of the bridge.
