Abstract

The invention belongs to the technical field of bridge inhaul cables, and particularly relates to an anti-icing ultra-durable inhaul cable. The anti-icing ultra-durable inhaul cable comprises cable strands, a protecting jacket coating outer layers of the cable strands, an electric heating wire connected with a power supply, and a switch controlling connection and disconnection between the electricheating wire and the power supply, adhesive tape is arranged on an outer layer of the protecting jacket in a spiral winding mode, the adhesive tape is arranged on the outer layer of the protecting jacket in a coating mode, bulged ribs are arranged on the outer surface of the adhesive tape in the longitudinal direction, and the electric hearting wire is arranged in the adhesive tape. The anti-icing and ice removal functions of the inhaul cable can be achieved while it is ensured that the inhaul cable has weather resistance and wind-rain induced vibration resistance.

Description

technical field

[0001] The invention belongs to the technical field of bridge cables, in particular to an anti-icing ultra-durable cable. Background technique

[0002] Cable-stayed bridges are favored by builders due to their large spanning capacity and beautiful shape. The number of cable-stayed bridges built or under construction at home and abroad is gradually increasing. Cable-stayed bridges have become the main bridges of long-span bridges in the transportation system. type one. Stay cables are the main load-bearing and force-bearing components of cable-stayed bridges, which are located on the bridge deck. At present, the commonly used cables include parallel steel wire cables, steel wire rope cables, steel strand cables, etc. When used, these steel cable bundles are generally extruded (wrapped) with high-density polyethylene (HDPE) as the outer sheath. At the same time, in order to solve the phenomenon of wind and rain induced vibration of the cable body during opera...
