The wrapping belt is a special rubber product designed for corrosion prevention and protection of the main cable of the suspension bridge. The wrapping belt can isolate the main cable from external influences such as light radiation, oxygen oxidation, rainwater erosion and the like in the external environment, and can independently or jointly complete the anticorrosion and protection performance of the main cable of the suspension bridge with a dehumidification system.

The suspension bridge anti-corrosion wrapping belt is wound on the outer layer of a bridge main cable in a spiral winding mode through special winding equipment, then the overlapped and wound wrapping belt is hot-melted, vulcanized and bonded into a whole through a special heating device, and a closed protective barrier is formed on the outermost layer of the bridge main cable. The heating device fuses the winding belt into a whole through hot melting, and simultaneously, the winding belt is shrunk and tightly wrapped on the main cable. The technology can make the main cable system form a complete closed protective layer.

The suspension bridge anti-corrosion wrapping belt cannot realize infinite length of the wrapping belt due to manufacturing, logistics and other reasons, and the overlapping condition of the wrapping belt frequently occurs in the construction process, so that a plurality of joints appear after the wrapping belt is constructed; the quality and the defects of the joint are key hidden dangers of sealing failure or uncontrollable; in order to solve the problem, the infinite length technology of the wrapping belt is realized, one wrapping belt is wound on the site, and the formation of defects is reduced as much as possible.
