Description

Technical Field

[0001] The present invention relates to the technical field of bridge cable wrapping, and more specifically, to a ducted fan-based sleeve-type cable wrapping device and wrapping method. Background Art

[0002] Cables (stayed cables, slings, main cables) are one of the main load-bearing systems of cable-stayed bridge structures. At the same time, the stays and slings are widely distributed on the cable-stayed bridge structure. Their cable forces bear the stress of the entire bridge structure and also affect the working state of the bridge. The environment above the cable-stayed bridge is complex and accompanied by humidity and strong winds. With the increase in the use time, the safety issues of the cable-stayed bridge structure operation have become increasingly prominent. Once the PE sheath on the surface of the cable-stayed bridge is broken or damaged, the steel wire rope inside the cable-stayed bridge will come into contact with the external humid environment, which will form electrochemical corrosion, thereby aggravating the rust of the cable-stayed bridge and even breaking the wire. Replacing the cable-stayed bridge is not only time-consuming and costly, but also requires traffic closure, and cannot fully realize the service life of the cable-stayed bridge. Therefore, wrapping the PE sheath on the surface of the cable-stayed bridge has an important impact on the protection of its internal steel wire rope. Wrapping the cable-stayed bridge structure can help maintain the PE protective sheath, extend the service life of the cable-stayed bridge, and reduce engineering costs. Summary of the invention
