Abstract
A protecting structure for the main cable of suspension bridge is composed of main cable made up of multistrand high-strength zinc-plated steel wire bundles, multiple cable clampers fixed to the main cable and multiple suspension cables fixed to the cable clampers. After the external surface of main cable is anticorrosively treated, a layer of steel wire or strip steel is wound arount it and the external surface of wound layer is treated for protection. Said anticorrosion treatment of main cable is to coat unsulfurized non-drying sealing rubber paste on it. Said protective layer of main cable has same service life as the primary cable.
Description
The present invention relates to the means of defence of a kind of main rope of suspension bridge system and the main cable protection structure that is obtained by this method, this main push-towing rope system comprises the main push-towing rope that is made of multiply high strength steel tow, be fixed on a plurality of cord clips on the main push-towing rope and be fixed on hoist cable on each cord clip.
The be supported on king-tower saddle of modernization on the suspension bridge is connected with bridge floor case beam by the hoist cable that is fixed on the cord clip with main push-towing rope on the dispersed cable saddle, is the load-carrying construction of full-bridge.Main push-towing rope is made of the finer wire that surpasses more than 10,000 usually, the steel tendon that becomes to have the circular cross-section of being roughly by the cord clip jam-packed.It is vital that the main push-towing rope system is taked effective anti-corrosion protection.
The flat 10-77604 Japan Patent of JP prospectus, a kind of anti-corrosion method of main rope of suspension bridge is disclosed, the outermost surface of the circular cross-section cable bundle that constitutes at the high-strength galvanized steel wire of giving determined number with circular cross-section applies the corrosion-inhibiting coating of drying oil of containing the paste aluminum phosphate and so on, twine the band that the approximate S shape in cross section, both sides have the wedge shape mate then, apply the coating of from epoxy coating, carbamate coatings and fluorine resin coating, selecting in its outside then.Because the dryness main body of oil is the glyceride of unrighted acids such as leukotrienes, linoleic acid, can harden after the oxidation, lose adhesion property to metal, influenced by variations in temperature and fluctuating load, crackle may appear, cause the reduction of antiseptic property.
Purpose of the present invention is intended to overcome the deficiency of above-mentioned prior art, and a kind of modified form main rope of suspension bridge safeguard structure that can implement the method for effectively protection and form thus the main rope of suspension bridge system for a long time is provided.
Above-mentioned purpose is to realize by the means of defence according to main rope of suspension bridge of the present invention system, this main push-towing rope system comprises the main push-towing rope that is made of multiply high strength steel tow, be fixed on a plurality of cord clips on the main push-towing rope and be fixed on hoist cable on each cord clip, twine layer of steel wire or band after the outer surface process internal layer preservative treatment of described main push-towing rope, outer surface at steel wire or band winding layer carries out outer protective treatment then, and wherein the internal layer preservative treatment is included in the step of the outer surface coating non-vulcanization type rubber non-drying sealing compound of described main push-towing rope.
This non-vulcanization type rubber non-drying sealing compound adopts polyisobutene non-drying sealing compound in a kind of preferred embodiment, and before the step of described coating non-drying sealing compound, applies one deck metal conditioner in advance at the outer surface of main push-towing rope.
According to the present invention, described outer protective treatment comprises the steps: to apply metal conditioner at the outer surface of steel wire or band; Apply MIO epoxy primer at metal conditioner layer external surface; Apply the polysulfur type waterproof sealing agent at the print paint layer of epoxy mica iron external surface; Apply the non-yellow stain type polyurethane finish at polysulfur type waterproof aquaseal layer external surface.
According to the present invention, a kind of main rope of suspension bridge safeguard structure of improvement also is provided, this main push-towing rope is made of multiply high-strength galvanized steel wire bundle, the steel tendon outer surface has interior anticorrosive coat, steel wire or band winding layer and external protection coating from inside to outside successively, and wherein interior anticorrosive coat comprises one deck non-vulcanization type rubber non-drying sealing compound.
In a kind of preferred embodiment, this non-vulcanization type rubber non-drying sealing compound is polyisobutene non-drying sealing compound, anticorrosive coat also has the metal conditioner layer that is arranged on the steel tendon outer peripheral face in described, and described external protection coating comprises metal conditioner layer, print paint layer of epoxy mica iron, polysulfur type waterproof aquaseal layer and the non-yellow stain type polyurethane finish layer on the outer surface that is successively set on steel wire or band winding layer from inside to outside.
Means of defence according to main rope of suspension bridge of the present invention system, apply non-vulcanization type rubber non-drying corrosion inhibiting sealant at the outer surface of main push-towing rope, polyisobutene non-drying sealing compound for example, the internal layer anticorrosive coat of formation, have good sealing corrosion performance, the main push-towing rope steel tendon is had extremely strong adhesiveness.Because saturation ratio height in its molecular structure has high inertia to light, heat, ozone etc., can keep soft condition for a long time, and is non-sclerous, not dry and cracked, do not go mouldy, in seal cavity, its Acceptable life reaches 80～100 years, can with the same longevity of main push-towing rope.Both can protect main push-towing rope long-term effectively, reduce maintenance cost again.
Method of the present invention has constituted a complete preservation system to the main rope of suspension bridge system.The metal conditioner that applies at main push-towing rope steel tendon and steel wire or band winding layer external surface has phosphorization and repair function to the mechanical damage on galvanized steel tow surface, and can increase the adhesive power of organic coating and metal surface; The MIO epoxy primer that adopts has water permeability, the gas permeability that reduces coating, opposing water, oxygen, electrolyte corrosion, and the function of passivating metallic surfaces has long-acting corrosion inhibition and corrosion resistance; The polysulfur type resistance erosion sealant that adopts has good water-fast, heat-resisting, oil resistant, anti-atmospheric aging and resistance erosion defencive function, good adhesive property and stretch-proof performance; The polysulfur type waterproof sealing agent that adopts has excellent water-resistant stability, good adhesive property and stretch-proof performance; The non-yellow stain type polyurethane finish that adopts has good ultraviolet-resistant aging, water-fast, salt spray resistance and resistant to chemical media, good pliability and stretch-proof performance.The performance of each coating cooperatively interacts, and mutually supports, to the rule section of main push-towing rope and irregular section, cord clip and hoist cable has been formed complete protection system.
