Abstract
The invention relates to a technical method for paving road steel bridge decks by combined applications of various composite paving materials. The technical method comprises an adhesive layer, a coiled material and bulk materials. The technical method is characterized in that the adhesive layer, the coiled material and the bulk materials are paved and tamped successively and hierarchically, wherein the adhesive layer is a spraying coating which are waterproof and rustproof and has strong adhesion to the rigid bridge deck; the coiled material is a sheet and windable spread paving material which is formed by using inorganic, high-strength, low elastic knitted fabric as a support grid structure and polyurethane asphalt concrete as a filling material; and the bulk materials are modified asphalt concrete with much coarse aggregate, slag, asphalt and little fine aggregate. Compared with a conventional method, the technical method provided by the invention is characteristics of waterproof and anti-corrosion protection steel bridge deck, synergetic reinforced bridge deck rigidity, anti-extension, anti-shift and anti-breakage, difficult appearance of delamination, cracks, tracks and pushed piles, antifatigue, aging resistance and the like. Besides, the technical method has the advantages of strong industrial production adaptability, less materials, low cost, simple repair and maintenance, etc. Therefore, the technical method has very good prospects for popularization and applications.
Description
One, technical field:
The present invention relates to the highway steel bridge deck paving, particularly the multiple composite paved material use in conjunction technical method of highway steel bridge bridge floor of mating formation.
Two, background technology:
Support the stream of people, the logistics of economic vitality, follow socioeconomic fast development, quantity, mode and rate requirement to its passage are day by day huge and various, highway steel bridge is being played the part of more and more important role in passage shortcut and flow are provided, and the reliability that Steel Bridge is mated formation, stability and durability are direct, the most dominant key elements that guarantees the steel bridge function.Steel Bridge under prior art is mated formation and is mainly adopted the material of mating formation such as hot mixed asphaltic concrete, modified asphalt concrete, cast asphalt concrete, epoxy resin bituminous concrete, adopts individual layer or double-deck paving method to complete.Above pavement material and application scheme are all with himself advantage and characteristics, have been used in a large scale in different geographical and environment, simultaneously also because of its inherent character and functional defect, be difficult to satisfy and stand the test of the natural causes such as high temperature, low temperature, violent temperature difference conversion, wind carry, earthquake.The test of the unique properties such as steel bridge steel and erection method.The test of the social factor such as traffick is high-speed, large flow, large load, overload and human factor.The lobe of various degrees, transverse fissure, fragmentation, push away all many-sided deficiencies, problem and the defectives such as heap, rut, delamination, seepage etc. are anti-aging, antifatigue is not enough.Also exist difference and the problem of the cost such as one-time investment and maintenance, maintenance difficulty aspect.
Three, summary of the invention:
Technical assignment of the present invention is problem, deficiency and the defective that exists for prior art, a kind of anti-aging, endurance, anti-rolloff are provided, rub mill with the hands, be not prone to the problems such as rut, passing, delamination, fragmentation, the mat formation technical method of highway steel bridge bridge floor of waterproof, antirust, casual multiple composite paved material use in conjunction good, with low cost.
The objective of the invention is to be achieved through the following technical solutions:
the mat formation technical method of highway steel bridge bridge floor of one kind of multiple composite paved material use in conjunction, it comprises adhesive layer, coiled material and bulk cargo, it is characterized in that adhesive layer, coiled material and bulk cargo are successively, layering is mated formation and is rolled reality, adhesive layer wherein is for having waterproof, antirust function, physicochemical property is stable, spray paint with rigidity bridge floor strong adhesion, coiled material is with inorganic, high-strength, the low yarn fabric that plays makes to support rack, the sheet that combines take the polyurethane asphalt concrete as inserts, but clot expand pavement material, bulk cargo is that coarse aggregate is many, breeze is many, pitch is many, the modified asphalt concrete that fine aggregate is few.
Its described coiled material, bulk cargo can be again, three times successively, layering mats formation and rolls reality.
Multiple composite paved material use in conjunction of the present invention mat formation the highway steel bridge bridge floor technical method compared with prior art, have following significant advantage and characteristics:
1, the spray paint direct spraying of strong adhesion forms adhesive layer in Steel Bridge, effectively intercepts contacting of empty G﹠W and rigidity bridge floor, has effectively prevented oxidation and corrosion to the pontic surface.
2, the application of high strength, low elasticity braid in coiled material, restriction mat formation extension and the passing, enhancing anti-shearing force destructive characteristics of layer.
3, bulk cargo adopts the modified asphalt concrete of " three-many-one-little ", with the coiled material Application of composite, the harsh weather compliance of its modified asphalt concrete, indeformable, do not ftracture, the advantage of antifatigue, advantage cooperative reinforcing, the shortcomings and deficiencies that the polyurethane asphalt agent on crack resistance of concrete is cracked, anti-shearing, be difficult for pushing away heap, delamination, the seepage complementation that offsets.
4, adhesive layer, coiled material, bulk cargo Application of composite, making mats formation tempers toughness with gentleness, to the bearing capacity of outside, natural environment destructive power, and the internal stress of pontic self change and have more damping effect, easier quick absorption, transmission and dissipation, antifatigue, ageing resistance are stronger.
Thereby the mat formation technical method of highway steel bridge bridge floor of multiple composite paved material use in conjunction of the present invention has good value for applications.
Four, description of drawings:
Accompanying drawing 1 is the mat formation cross section structure schematic diagram of technical method of highway steel bridge bridge floor of multiple composite paved material use in conjunction.
Reference numeral: 1, rigidity bridge floor; 2, adhesive layer; 3, bulk cargo; 4, coiled material; 5, support rack; 6, inserts.
Five, the specific embodiment:
As shown in Figure 1, the mat formation technical method of highway steel bridge bridge floor of multiple composite paved material use in conjunction of the present invention, its structure comprises adhesive layer 2, bulk cargo 3 and coiled material 4.Adhesive layer 2 wherein for have waterproof, antirust, physicochemical property is stable, with the spray paint of rigidity bridge floor 1 strong adhesion.Coiled material 4 is to make to support rack 5 with inorganic, high-strength, the low fibril braid that plays, 6 sheets that combine take the polyurethane asphalt concrete as inserts, but clot and the pavement material that expands.Bulk cargo 3 is the modified asphalt concrete that coarse aggregate is many, breeze is many, pitch is many, fine aggregate is few.
During construction, rust cleaning and clean rigidity bridge floor 1 evenly tightly spray spray paint, solidify to form adhesive layer 2, and the coiled material 4 of mating formation rolls reality, and the bulk cargo 3 of mating formation rolls reality.According to demand or designing requirement with same process flow mat formation second, third layer coiled strip 4 and bulk cargo 3.
Except the described technical characterictic of manual, be the those skilled in the art known technology.
