Description
Technical Field
The utility model relates to the technical field of inhaul cables, in particular to a high-durability parallel steel wire inhaul cable body.
Background
Taking a cable-stayed bridge as an example, a stay cable is an important component of the cable-stayed bridge. And because the cable, the bridge tower and the main beam form a high-order hyperstatic structure, the change of the load of the vehicle on the bridge and the change of the environmental temperature can obviously influence the tension of the cable. Bridge cables are typically arranged outside the structure in an exposed environment and in a highly stressed state for a long period of time, and are very sensitive to environmental and stress corrosion, so the service life of the cable is largely dependent on the corrosion resistance of the cable body.
At present, a common parallel steel wire inhaul cable body is generally formed by winding fiber reinforced polyester strips on the outer surface after a plurality of single-coating (coating made of pure zinc or zinc-aluminum) steel wires are twisted, and then extruding a double-layer high-density polyethylene sheath. Although the cable body has certain corrosion resistance, the high-density polyethylene sheath is easy to damage in the construction process of the inhaul cable, so that the metal matrix is directly exposed to the external environment but not protected after the steel wire is exposed, and the durability and the service life of the cable body are affected.
The patent with the publication number of CN215210194U is found to disclose a high-durability type parallel steel wire inhaul cable body, which belongs to the technical field of bridge engineering. The steel wire bundle comprises a plurality of composite anti-corrosion coating steel wires, wherein a plurality of steel wires with the composite anti-corrosion coating are twisted and bundled to form a steel wire bundle, the outer surface of the steel wire bundle is wound with a fiber reinforced polyester belt, and the outer surface of the fiber reinforced polyester belt is provided with a double-layer high-density polyethylene sheath. The composite anti-corrosion coating steel wire comprises a high-strength steel wire, and a composite anti-corrosion layer is coated on the outer surface of the steel wire. The composite anti-corrosion layer comprises a metal coating, wherein the metal coating is coated on the outer surface of the steel wire, and an epoxy resin coating is coated on the metal coating. The composite anti-corrosion layer comprises a metal coating, wherein the metal coating is coated on the outer surface of the steel wire, an epoxy resin coating is coated on the metal coating, and a polyurea coating is coated on the epoxy resin coating. The utility model improves the corrosion resistance; the service life of the bridge inhaul cable is effectively prolonged, and the maintenance and replacement cost of the bridge inhaul cable is reduced. When the device is used, the following defects still exist:
the device realizes the service life of the bridge inhaul cable by coating the metal coating, the epoxy resin coating and the polyurea coating, but when the device is specifically used, after the high-density polyethylene sheath sleeved on the external side of the device is damaged, the inhaul cable body still has the possibility of corrosion in the process of blowing and insolating, and the service life of the inhaul cable still can be reduced after a long time.
