Description
Technical field
The present invention relates to a kind of overhead road of city paving steel bridge deck, especially relate to a kind of paving structure and paving method of modular steel bridge bridge floor.
Background technology
After 21 century, along with science and technology is constantly progressive, transport development cause has obtained development fast, steel box girder bridge due to have from heavy and light, easy construction fast, supporting capacity and the advantage such as span ability is large, application is expanding day by day, present stage urban elevated bridge in position large across footpath, that traffic impact large, service condition is relatively harsh, substantially all adopted steel box girder bridge.But, to compare cement concrete bridge condition more complicated for steel box girder bridge floor paving.
The first, it is mated formation and has relatively abundant beam-slab bracing system unlike cement concrete bridge, and steel plate thickness is all thinner, generally at 12～16mm, produces under external force whole and local flexing and is out of shape larger;
The second, large many of other earth working materials of steel plate thermal conductivity ratio, layer internal-external temperature difference of mating formation under megathermal climate is huge, and layer interior temperature of mating formation is very high, often reaches 80,90 ℃;
Three, steel plate is met water electrode and is easily got rusty, and not only between mating formation layer by layer, coheres, anti-shear ability produces significant impact, also can produce corrosion to steel case beam, affect application life;
Four, there is hogging moment in Steel Bridge Deck Pavement surface, and material bending resistance tensile stress, strain capacity are had higher requirement, and it is more outstanding that deck anti-fatigue performance, endurance quality seem;
So far, the developed country such as American-European-Japanese has carried out a series of further investigations for feature, the difficult point of paving steel bridge deck, has successively occurred take casting type asphaltic mixture that moral, English, method, Deng state the are representative scheme of mating formation; The epoxy resin asphalt that the U.S. is representative of the take double-deck modified asphalt SMA scheme that the states such as scheme and Germany, Japan adopt of mating formation, has basically formed the complete system of paving steel bridge deck that is applicable to its national feature.China is relatively late to the research of steel deck paving packing technique, until 20 end of the centurys, with Guangdong Steel deck pavement, be applied as starting point, the domestic large-span steel box girder bridge asphalt concrete pavement application period that just formally entered, but mainly take and indiscriminately imitate the complete pavement technique of Introduced From Abroad as main, applicability understanding to steel deck paving packing technique is often not enough, the severe condition shortcoming that domestic Steel Bridge Deck is used is considered, therefore, generally having there is comparatively serious earlier period damage phenomenon in the layer of mating formation, has occurred the diseases such as crack, rut and passing.
In addition, overhead road of city Steel Bridge Deck surface functional layer generally adopts traditional compact type bituminous concrete or macrovoid road structure, but these two kinds of road surface structare layers but exist many problems in actual application: 1) skid resistance of road surface rainy day, travel safety become main problem; 2) road traffic noise is having a strong impact on people's normal life; 3) flexible pavement and cement pavement have larger heat absorption rate, and city temperature is day by day climbed to a higher point, and city hot island phenomenon becomes clear day by day; 4) road surfaces layer supporting capacity is on the weak side, occurs further by the phenomenon of densification; 5) hole decay is just very obvious at short notice, and drain function is had a strong impact on; 6) it is inner that rainwater etc. infiltrates deck, and the useful life longevity of substructure layer is produced and had a strong impact on; 7) snow-melting agent or acid rain etc. produce corrosion to deck, cause road surfaces to peel off, cheat the phenomenons such as groove.
The patent No. 200910152726 and application number 201110298046.2 all disclose a kind of steel bridge deck paving structure and paving method, each functional layer mainly for Steel Bridge has been done different improvement, but the waterproofing course for the layer of mating formation, they all still adopt the coating of water proofing asphalt coating to form, therefore this single waterproof body ties up to after the long-term crimp of road surfaces, easily go to pot and produce infiltration, cause inner serious safe road to suffer from.
To sum up, for the real behavior in service of overhead road of city steel box girder bridge face, in the urgent need to developing a kind of new material, and design a kind of reliable in quality, construct convenient, comprehensive cost is relatively cheap and the life-span is longer, is applicable to paving structure and the paving method thereof of the modular steel bridge bridge floor of urban road.
