Background

The coating anticorrosion system is used as an effective anticorrosion measure and is widely used for repairing a defect coating of the marine steel pipe pile and preventing corrosion of severe corrosion zones such as a splash zone, a water level change zone and the like. At present, a common coating anticorrosion system is generally composed of components such as anticorrosion paste, an anticorrosion belt, anticorrosion armor, fasteners and the like. The construction steps of the coating anticorrosion system generally comprise the steps of preparation before construction, steel pile surface treatment, coating anticorrosion paste, winding an anticorrosion belt, mounting a protective cover, fastening bolts, sealing end parts and the like. For repairing the coating in the atmospheric region, a construction platform is generally constructed by a scaffold, and a support platform is provided for the subsequent working steps. For the coating repair of the part below the atmospheric region, the construction is mainly performed by divers. However, since the offshore environment is complex, the construction of coating the anticorrosion system is often restricted by a plurality of factors, and the construction efficiency and effect are seriously affected. For example:

(1) influenced by factors such as wharfs, cross-sea bridge structures, sea waves and ship fixing, the platform is constructed through the scaffold, a large amount of personnel and ship-aircraft are matched in a coordinated mode to be implemented smoothly, and a large amount of manpower and material resources are consumed. After the construction is finished, the transportation, the removal and the like of the scaffold also need to consume large manpower and material resources.

(2) When divers are working in sea water, great efforts are needed to maintain balance due to the lack of good support points. Particularly, when the construction is carried out in flowing seawater (such as river mouths and the like), the balance is more difficult to maintain, and the construction efficiency and the construction effect are seriously influenced.
