Description
Technical field:
The present invention relates to a kind of drag-line, especially relate to a kind of Supehigh strength parallel steel wire durable cables.Be mainly used in cable-stayed bridge and make suspension cable.
Background technology:
Cable-stayed bridge is a kind of from the anchor structure system, and it does not need the anchor pier structure of the huge costliness at drag-line two ends, and its Suo Yingli is that Yan Suochang is constant basically.The cable-stayed bridge layout that in striding, is in line, and have suitable extensional rigidity.Suspension cable produces favourable pressure to the girder of bridge span structure, has improved the stress of girder.Suspension cable is very big to the influence of cable-stayed bridge, and the reason of cable-stayed bridge failure mainly all is the problem of cable in history.Because suspension cable generally is arranged in the beam external body, and be under the high-stress state for a long time, its sectional dimension is again little, so it is very responsive to corrosiveness, even taking place, its intensity of slight corrosion also has bigger loss, so the durability of cable-stayed bridge depends on the resistance to corrosion of suspension cable to a great extent.Suspension cable should have under the effect the enough intensity except carrying in sound, the most important thing is that suspension cable is comprising on the whole suspension cable length of anchoring section having reliable and durable anti-corrosion protection measure.At present the suspension cable of cable-stayed bridge generally adopts the hot extruded polyethylene drag-line, this drag-line resistance to corrosion a little less than, cause the cable-stayed bridge poor durability that adopts this drag-line.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, provide that a kind of resistance to corrosion is strong, the Supehigh strength parallel steel wire durable cables of long service life.
The object of the present invention is achieved like this: a kind of Supehigh strength parallel steel wire durable cables, the ground tackle that comprises cable body and be fitted in the cable body two ends, dragline structure are divided into two kinds:
One, the steel tendon outer surface of drag-line cable body twines the perfluorinated membranes adhesive tape of being made by fluorine resin material earlier, this adhesive tape has very good mechanical properties and ductility and chemical-resistance, twine fiber reinforcement polyester band again and claim pressure sensitive adhesive tape again, its tensile strength is not less than 950N/25mm, make the steel tendon moulding, outer then double-deck high density polyethylene (HDPE) sheath, the internal layer black of squeezing, outer colored, carry out embossing at the drag-line outer surface at last and handle.
Two, anticorrosion filler grease or paraffin are filled in the steel wire of the steel tendon of drag-line cable body and the gap between steel wire, the steel tendon outer surface twines the perfluorinated membranes adhesive tape of being made by fluorine resin material earlier, this adhesive tape has very good mechanical properties and ductility and chemical-resistance, twine fiber reinforcement polyester band again and claim pressure sensitive adhesive tape again, its tensile strength is not less than 950N/25mm, make the steel tendon moulding, outer then crowded double-deck high density polyethylene (HDPE) sheath, internal layer black, outer colored, carry out embossing at the drag-line outer surface at last and handle.
Major technique characteristics of the present invention are:
1) cable body adopts the comprehensive anticorrosive technology, carries out the multilayer protection;
2) the ground tackle coating adopts the Zinc-Chromium film coating to claim the Dacroment coating again, this coating is thinner, does not influence the tolerance fit of ground tackle screw thread, no hydrogen embrittlement phenomenon, but have fabulous permeability and toolability and high antiseptic property, the anticorrosion life-span that makes this dragline anchorage is 6～7 times of common dragline anchorage;
3) novel anchoring casting process is adopted in the anchoring between ground tackle and the steel wire, has guaranteed the anchoring strength while of suspension cable, and has improved anti-fatigue performance;
4) adopt novel filling sealing technology between ground tackle and the drag-line, prevented that harmful substance such as moisture content from entering cable body, avoided corrosion hidden danger.
5) drag-line cable body outer surface carries out the embossing processing, when its air resistance coefficient does not obviously increase, has extremely significant rain-proof effect.
The technical indicator of Supehigh strength parallel steel wire durable cables is as follows:
| Sequence number | Project | Require index |
| 1 | Tensile strength | 〉= |
| 2 | Tension performance | After drag-line surpasses stretch-draw according to 1.2～1.5 times design load, value＜the 6mm that contracts in the body of casting of cold and hot casting anchor, screwing of anchor circle and anchor cup is unaffected |
| 3 | Elastic modelling quantity | 〉=1.90 * 10 5Mpa |
| 4 | The disrumpent feelings percentage elongation of static load | 〉=2% |
| 5 | The static load performance | 95% of static load Breaking load 〉=disrumpent feelings load of suspension cable nominal |
| 6 | The dynamic load performance | The finished product drag-line is by being limited to 0.45 σ on the stress b, stress amplitude is 200MPa, after the fatigue test of 2,500,000 secondary stress conditions, drag-line is no abnormal. |
| 7 | Endurance quality | Suspension cable service life＞50 year |
| 8 | The suspension cable outward appearance | The suspension cable outer surface is even, smooth, smooth, flawless |
| 9 | Drag-line length precision | During less than 200m, the length precision reaches ± and 1/10000, during more than or equal to 200m, the length precision reaches ± (1/20000+10) |
| 10 | The coiling performance | The drag-line diameter of coiling internal diameter 〉=20 times |
| 11 | The anti-wind, rain and vibration performance | Air resistance coefficient is Cd=0.62, and rain-proof is respond well |
Compare with common hot extruded polyethylene drag-line, the present invention has advantages such as antiseptic property is good, intensity is high, anti-fatigue performance good, the elastic modelling quantity loss is little, in light weight, easy construction, has satisfied the instructions for use in 50～60 years of super long span stayed-cable bridge suspension cable.
