Anti-compression cable for melting snow and ice on road and bridge

Abstract

The invention discloses a road and bridge anti-compression cable for melting snow and ice. The cable comprises a cable body wrapping group, a crosslinked polyethylene layer and a stainless steel woven mesh sleeve layer, wherein the crosslinked polyethylene layer is used as an outer wrapping layer, and the stainless steel woven mesh sleeve layer is used as an armor layer and sequentially wraps the cable body wrapping group from inside to outside; the cable body package is composed of two internal copper wire conductive layers, two tensile cables and a compression-resistant insulating flame-retardant layer wrapping the internal copper wire conductive layers and the tensile cables, compression-resistant insulating flame-retardant filler is filled among the internal copper wire conductive layers, the tensile cables and the compression-resistant insulating flame-retardant layer, and the number of the internal copper wire conductive layers and the number of the tensile cables are both two. And the internal copper wire conductive layers and the tensile cables are distributed in a staggered manner. Wherein the tensile cable is used as a main tensile resistance source of the cable and is composed of a plurality of basalt fibers; the crosslinked polyethylene layer is used as an outer cladding layer, and the stainless steel woven mesh sleeve is used as an armor layer. By arranging the cable body package group, the overall closing performance of the cable is improved, the overall tensile, compression-resistant, wear-resistant and waterproof performance of the cable body is enhanced, the chemical performance of the cable is stable, and the service life of the cable is prolonged.

Description

technical field [0001] The invention belongs to the field of engineering, and relates to a road and bridge snow-melting and ice-melting technology, in particular to a pressure-resistant cable for road and bridge snow-melting and ice-melting. Background technique [0002] As the current main method of melting snow and ice on roads and bridges, the electrothermal method requires cable transmission to generate heat. When the heating line is connected by a cable, there are the following problems: [0003] 1. Most of the cables currently existing are solid cables, which are heavy and inconvenient for construction, and the cables have insufficient tensile and compressive properties. When the cables are pulled or squeezed under the friction of the wheels, the cables will be damaged by tension and compression, and the circuit will be interrupted, resulting in equipment failure. Faults, unable to meet expectations; [0004] 2. When the cable is buried in the road, it bears part of t...
