[0002] The arch ribs of steel tube concrete arch bridges are usually processed in large sections in the factory, then anti-corrosion painted, and finally transported to the bridge site for installation. As a steel-concrete composite structure, the quality of the arch rib anti-corrosion coating directly affects the life cycle of the arch bridge, and the quality control of anti-corrosion spraying needs to be highly valued. Traditionally, vertical spraying is mostly used for steel tube arch rib spraying. However, for arch bridges with larger spans, the radial height of the arch ribs can reach more than 10m, which will inevitably increase the height of the steel structure anti-corrosion coating plant to meet the needs of the structural size.
