It was analyzed briefly corrosion environment and types of main cable steel wire of suspension bridge,it was researched the coating of protecting main cable steel wire of suspension bridge.It was also analyzed domestic typical coating technology of protecting main cable steel wire of suspension bridge,and was introduced the progress in two kinds of new coating technologies of protecting main cable steel wire of suspension bridge.
The utility model relates to a sealed protective coating structure for a main cable wrapping section of a suspension bridge, which belongs to the technical field of bridge protection. The sealed protective coating structure comprises an inner sealed protective layer wrapped with a silane-modified polyether sealant outside the main cable wire. A flexible strap wrapping layer is attached to the inner sealed protective layer, an outer sealed protective layer wrapped with the silane-modified polyether sealant is attached to the flexible strap wrapping layer and a finish coating wrapped with flexible polyurethane finish or flexible fluorocarbon finish is attached to the outer sealed protective layer. The utility model has the advantages of simple structure, convenience for construction, obvious and reliable performance and good practicality.
