The main load-bearing structure of a steel-framed bridge is a bridge made of steel, that is, a steel structure bridge or a steel bridge. The beams and legs or piers form a rigid connection. The structural forms can be divided into portal rigid frame bridges, inclined leg rigid frame bridges, T-shaped rigid frame bridges and continuous rigid frame bridges. In the construction process of this steel structure bridge building, sandblasting and rust removal procedures are often required. Sandblasting and rust removal uses compressed air as the power to form a high-speed jet beam to spray the material at high speed onto the surface of the workpiece to be processed, so that the appearance or shape of the workpiece changes. The steel structure body is surface treated through the sandblasting and rust removal process, thereby playing a rust-proof role during long-term use.

A sandblasting machine is usually used in conjunction with a nozzle structure and manual operation to sandblast the components. When the column components have been installed and still need to be sandblasted for the second time, high-altitude sandblasting is required, which is very inconvenient and poses a safety hazard.
