Abstract
The invention discloses a steel wire stayed cable, which comprises a plurality of steel wires, an internal protection sleeve layer and an external protection sleeve layer, wherein a plurality of steel wires are stranded to form one wire steel bundle; a plurality of wire steel bundles are stranded to form one wire steel core; at least two wire steel cores are provided; the internal protection sleeve layer covers each of the steel wire cores; at least two steel wire cores covered with the internal protection sleeve layer are stranded to form one steel wire general core; the external protection sleeve layer covers the steel wire general core; and filling material is set between the steel wire general cores covered by the external protection sleeve layer. According to the invention, the technical problem that potential safety hazard exists in the stayed cable due to short service life caused by poor stability of the steel wire stayed cable in the existing technology is overcome, thus improving the use value, the stability and the safety of the steel wire stayed cable and also prolonging the service life of a bridge.

Existing application number is 90211306.2, publication number is the Chinese patent " wire digging line of multilayer proofing " of 2068534, disclose a kind of wire digging line of multilayer proofing, steel tendon there is plastic sheath, it is characterized in that: have metal zinc layers between steel tendon surface and plastic sheath, zinc layers is sprayed with one deck aluminium, copper or chromium metal level.But the wire digging line steadiness of this utility model is poor, causes application life short, makes cable stayed bridge there is potential safety hazard.
Summary of the invention
The object of the invention is to overcome the problems referred to above that in prior art, wire digging line exists, propose a kind of wire digging line.Instant invention overcomes prior art, to there is wire digging line steadiness poor, causes application life short, make cable stayed bridge there is the technical problem of potential safety hazard, improve the use value of wire digging line, steadiness and safety, also extend the application life of bridge.
The present invention realizes by the following technical solutions:
Wire digging line, it is characterized in that: comprise many steel wires, inner restrictive coating and external sheath layer, described many steel wires are twisted into a steel tendon, many steel tendons are twisted into a wire-core, described wire-core is at least two, and described inner restrictive coating is coated on every root wire-core, and at least two wire-cores being coated with inner restrictive coating are twisted into the total core of steel wire, described external sheath layer is coated on the total core of steel wire, is provided with packing material between the total core of the described steel wire coated through external sheath layer.
The thickness of described inner restrictive coating is 1cm-1.5cm.
The thickness of described external sheath layer is 1cm-2cm.
Described inner restrictive coating and external sheath layer are plastic layer.
Compared with prior art, its advantage is in the present invention:
1, instant invention overcomes prior art, to there is wire digging line steadiness poor, causes application life short, make cable stayed bridge there is the technical problem of potential safety hazard, improve the use value of wire digging line, steadiness and safety, also extend the application life of bridge.
2, the present invention adopts inside and outside two restrictive coating, and the thickness of inner restrictive coating is 1cm-1.5cm, and the thickness of external sheath layer is 1cm-2cm, adds the steadiness of wire digging line, thus adds the steadiness of bridge, extends the application life of bridge.
3, the present invention adopts sheath and external sheath layer to be plastic layer, and plastics cost is low, and has certain anti-corrosion function, easy to use.
4, the present invention adopts at least two wire-cores being coated with inner restrictive coating to be twisted into the total core of steel wire, can strengthen the steadiness of wire digging line further; Compared with prior art structure is more firm, and steadiness is stronger, the long service life of wire digging line.
