Description

A kind of bridge deck pavement structure
Technical field
The utility model relates to the steel bridge road surface pavement structure that highway construction is used, and relates in particular to a kind of bridge deck pavement structure.
Background technology
In recent years, along with the further input of China's capital construction cause and the raising of construction technology, bridge, as the convenient form of structure of crossing over river, river, paddy and road main line, has obtained significant progress, as Nanjing second Yangtze Bridge, the Wuhan Baishazhou Yangtze Bridge, dam, Guizhou linghe bridge etc.But, China's all steel box girder bridge flexible pavements paving structure more or less all has problems at present, and, more greatly across footpath heavy duty bridge, the service condition of deck installation structure all can not be satisfactory, early stage infringement phenomenon is commonplace, and Partial Bridges almost all needs to keep in repair punishment every year.
In bridge deck pavement structure, epoxy asphalt mixture, as a kind of thermosets, is being played the part of extremely important role.It has good high-temperature stability and mechanical property, at high temperature especially has good anti-loaded deformation ability, is widely used in domestic many large-span steel box girder bridge floor paving structures.But, because common bituminous epoxy enbrittles greatly under cryogenic conditions, the shortcoming of poor toughness, thereby adopt common epoxy asphalt mixture easily to cause the cold cracking of Steel Bridge Deck Pavement, for current safety and the structure durability of bridge have been buried hidden danger.
Utility model content
The purpose of this utility model is to provide a kind of bridge deck pavement structure, and this bridge deck pavement structure has excellent pavement performance and low-temperature cracking-resistance.
The purpose of this utility model is achieved in that
, it is characterized in that: it is included in anticorrosive coat, water-proof tack coat and the layer of mating formation of laying successively from bottom to top on steel bridge deck; The described layer of mating formation comprises mat formation upper strata and the lower floor of mating formation, and the upper strata and to mat formation between lower floor be conventional commercially available epoxy bond layer of mating formation.
The above-mentioned upper strata of mating formation is for conventional commercially available epoxy asphalt concrete layer, and its thickness is 3 ~ 6cm.The upper strata of mating formation of this thickness can further improve high temperature rutting resistance and the weatherability of this layer of epoxy asphalt mixture.This epoxy asphalt concrete layer, specifically can select the disclosed composite modified asphalt of preparing by compound interpolation polyurethane modified epoxy resin in Chinese patent 201310181013.9 " a kind of composite modified asphalt and preparation method thereof ", and gather materials and prepare this epoxy asphalt concrete layer through mixing interpolation routine.And the upper strata of mating formation that this epoxy asphalt concrete layer is done, not only have common epoxy asphalt mixture excellence high-temperature stability and mechanical property, and by the modification of polyurethane, its anti-cold cracking, pliability, anti-fatigue performance are improved greatly.The above-mentioned lower floor of mating formation is conventional pouring asphalt concrete layer, and thickness is 2.5 ~ 4cm.The lower floor of mating formation of this thickness can increase the waterproof ability of deck installation structure, reduces high temperature disease simultaneously.The lower floor of mating formation of this pouring asphalt concrete layer, under construction temperature, there is mobility, adopt the method for mobile construction, do not need to roll, construct very convenient, and it is little to have void content, dense water is good, the feature of deformation performance and anti-fatigue performance excellence, can be good chase after from steel plate deformed, not easy to crack.
Above-mentioned epoxy bond layer, its thickness is 1~3mm, optimum thickness is 3mm.
Above-mentioned anticorrosive coat is conventional commercially available epoxy zinc-rich enamelled coating, and thickness is 0.01~0.1mm.This anticorrosive coat can play the effect of protection steel plate, prevents the moisture in steel plate ingress of air and produces corrosion.
Above-mentioned water-proof tack coat is conventional commercially available methacrylic resin adhesive layer, and thickness is 1 ~ 5mm, and optimum thickness is 3mm.This water-proof tack coat can prevent from oozing under moisture, has avoided steel plate and steel work to be corroded, and simultaneously by steel plate and bituminous concrete bonding, makes steel plate and the integral body of layer formation of mating formation, and jointly bears vehicular load, improves the durability of bridge floor.
The utlity model has following advantage:
1) the utility model is established anticorrosive coat, waterproofing tack coat and the layer of mating formation on upper berth, steel bridge road surface, it is rational in infrastructure, intensity is high, modulus is moderate, can thoroughly completely cut off moisture content, formed the integrated function layer of bonding, waterproof, stress buffer, abrasion performance, guarantee the waterproof effect of steel bridge paving, extended the application life of steel bridge road surface pavement structure, reduced maintenance cost;
2) the upper strata construction technology of mating formation in the utility model is very convenient, construction temperature is 120 ℃, the construction temperature of relatively common bituminous mixture is lower, has saved a large amount of heat energies, and has reduced the discharge of toxic and harmful in a large amount of greenhouse gases and asphalt heating process;
3) the epoxy bond layer in the utility model has good compatibility, mixes rear not stratifiedly, has improved the durability of compound and paving structure;
4) bridge deck pavement structure in the utility model has very excellent anti-cold cracking and combining structure anti-fatigue performance.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of the bridge deck pavement structure described in the utility model embodiment 1.
The specific embodiment
Be below the utility model preferred embodiment, and be not intended to limit protection domain of the present utility model.
Embodiment 1
As shown in Figure 1: a kind of bridge deck pavement structure, it is included in anticorrosive coat 2, the water-proof tack coat 3 of laying successively from bottom to top on steel bridge deck 1, the lower floor 4 of mating formation, commercially available epoxy bond layer 5 and the upper strata 6 of mating formation of routine; Wherein, anticorrosive coat 2 is conventional commercially available epoxy zinc-rich enamelled coating, and its coating thickness is 0.03mm; Waterproofing tack coat 3 is conventional commercially available methacrylic resin layer, and its coating thickness is 3mm; Mat formation lower floor 4 for pouring asphalt concrete layer, and its thickness is 3.5cm; Epoxy bond layer 5, its coating thickness is 3mm; Mat formation upper strata 6 for epoxy asphalt concrete layer, its thickness is 4cm, wherein this epoxy asphalt concrete layer is to select the disclosed composite modified asphalt of preparing by compound interpolation polyurethane modified epoxy resin in Chinese patent 201310181013.9 " a kind of composite modified asphalt and preparation method thereof ", and prepares conventional gathering materials through mixing to add.
During construction, first steel bridge deck 1 is carried out to processing of rust removing, make its requirement that meets spatter property and roughening, then spraying corrosion resistant coating 2, after anticorrosive coat 2 is completely air-dry, spraying waterproofing tack coat 3, after waterproofing tack coat 3 solidifies, the lower floor 4 of mating formation that the moulding pouring asphalt concrete layer that paves is done, after the lower floor 4 of mating formation solidifies, the epoxy bond layer 5 that spraying is conventional commercially available, after this epoxy bond layer 5 solidifies, re-lays the upper strata 6 of mating formation that epoxy asphalt concrete layer is done.
