Description
Technical field
The present invention relates to a kind of drag-line, particularly a kind of wire digging line of filling or being coated with polyurea protection material.
Background technology
Compressor wire drag-line is the stressed member of a kind of key in bridge construction, requires to have higher anti-corrosive durability; Current prestressing force bridge wire digging line is manufactured with reference to standard GB/T/T18365-2001 " cable stayed bridge hot extruded polyethylene high tensile steel wire drag-line technical condition " usually.
The corrosion of compressor wire is the stress corrosion (belonging to couple corrosion category) under stress and corrosion compound action, and be characterized in first forming crackle in metal inside, internal fissure just forms stress after occurring and concentrates, and accelerates the development of crackle, and then produces heavy corrosion.Anticorrosion plating (painting) the layer steel of compressor wire are always on active service under the condition of corrosive medium, by the kind of topping, can be divided into on-metallic protective coating (being called coating), chemical coating and coat of metal (being called coating) three class.1, the nonmetallic coating of nonmetal protective coating prestressing steel mainly contains plastics, epoxy resin and anticorrosion grease three kinds at present, but the anti-aging problem of nonmetallic coating not yet solves, and its mechanical property is much lower compared with the coat of metal.Therefore, range of application is restricted.2, chemical coating is by chemical method, forms topping in metal surface, as the passivation of zinc layers, the oxidation of aluminium lamination, the phosphatization etc. of iron-based.Such topping is not often as single steel topping, but annexs with the coat of metal and use.3, metal coating coating is in couple corrosion, and first the metal being in anode is dissolved, and plates with the metal sprinkled compared with ironwork, as zinc, aluminium etc. in Steel Wire Surface for this reason.In the environment of corrosive medium, making zinc first be protected iron-based by dissolving, being called that anode coating is protected.Because zinc-plated (or Zn-Al alloy) exists " hydrogen embrittlement " phenomenon, reduce the strength grade of steel wire, always controversial.Therefore compressor wire anticorrosion is the significant problem to closing bridge engineering quality life-span, must strengthen truly feasible anti-corrosion measure, the massive losses brought to reduce compressor wire to lose efficacy in advance because corrosion causes for prestressing force steel wire.
Polyurea materials reacts by isocyanate component and amino-compound component a kind of elastomer substances generated, and is divided into pure polyureas and half polyureas, and the most basic characteristic of polyureas is exactly anticorrosion, waterproof, wear-resisting etc., is mostly used in space industry at present.

Owing to taking above technical scheme, a kind of wire digging line of filling or being coated with polyurea protection material of the present invention has following characteristics and beneficial effect:
1. greatly can improve anticorrosion, the damping of wire digging line, cling property, postpone drag-line application life.
Because the filling of the present invention or the wire digging line that is coated with polyurea protection material are the steel wire combination bodies be made up of many steel wires, have following three kinds of primary structure forms, between each bright steel wire of n root steel wire, between gap or the anticorrosion steel wire of n root, gap-fill has polyurea materials to form wire digging line I a or filling that fill or be coated with polyurea protection material or wire digging line II a being coated with polyurea protection material; Be coated with one deck polyurea protection coating at the outermost layer of steel wire combination body and form wire digging line I b or filling that fill or be coated with polyurea protection material or wire digging line II b being coated with polyurea protection material; Or the outermost layer of steel wire combination body have one be wrapped band, the band that is wrapped skin be coated with polyurea protection coating II and form wire digging line I b0c, II b0c that fill or be coated with wire digging line I a0c, II a0c of polyurea protection material or filling or be coated with polyurea protection material; Again by the filling of these three kinds of structures or be coated with polyurea protection material wire digging line based on, at the skin of steel wire combination body or by an individual layer HDPE sleeve pipe or by the double-deck HDPE sleeve pipe be made up of internal layer HDPE sleeve pipe and outer HDPE sleeve pipe, or outer there is the filling of individual layer HDPE sleeve pipe or be coated with the individual layer of wire digging line of polyurea protection material or the skin of double-deck HDPE sleeve pipe is also coated with the wire digging line that one deck polyurea protection coating III formation has the band polyurea protection coating of multiple protective forming; Because polyurea materials has excellent abrasion resistance, impact resistance and damping property, be coated on the Steel Wire Surface of wire digging line matrix, its coating is continuous, fine and close, can accomplish without seam, free of pinholes, moisture content in isolated air and the infiltration of oxygen, the epoxy coating that steel wire and Steel Wire Surface can be protected to be attached with, plastic coating or anticorrosion grease coating are not easily aging, the easy loss of galvanizing coating can be slowed down, be subject to the impact of the local defects such as pin hole, greatly improve the antiseptic power of such wire digging line, and increase its anti-wear performance, extend the application life of wire digging line; Simultaneously polyurea materials has excellent tensile strength, the characteristic such as ageing-resistant, wear-resistant, the damage caused because constructing operation is improper in the manufacturing and installation process can be reduced, not easily produce cracking, obscission, greatly improve the antiseptic power of wire digging line, increase the service life.
2. between compact conformation, steel wire, frictional force is large, strengthens its cling property, and fatigue resistance improves:
The filling of the present invention or be coated with in the steel wire outmost surface of wire digging line of polyurea protection material and gap and all apply or be filled with polyurea materials, because polyurea materials has the physical property of high abrasion, therefore, polyurea coating need not be very thick, when they are formed presstressed reinforcing steel, can in regular hexagon or the arrangement of unfilled corner Hexagonal close or the arrangement of other forms between each steel wire, compact conformation, the frictional force of wire digging line can be strengthened, strengthen its cling property; More be conducive to using under the operating mode of Sarasota both sides by out-of-balance force at bridge cable.
3. the present invention can improve the performance of existing coating or coating wire, thus also greatly improves the antiseptic power of wire digging line, and increases its abrasion resistance, extends the application life of wire digging line.
Below, in conjunction with the accompanying drawings and embodiments a kind of technical characteristic of filling or being coated with the wire digging line of polyurea protection material of the present invention is further described.
