(3) summary of the invention
Summary of the invention of the present invention is the form of structure and the connected mode of FRP-epoxy gravel-bituminous concrete paving steel bridge deck new construction.
Technical scheme of the present invention is as follows: in the middle of material property great disparity, interface connect more weak steel bridge deck and asphalt concrete pavement layer, but add not only can realize the two material stiffness transition, but also the interface connect the FRP that strengthens layer and the epoxy gravel layer of mating formation of mating formation, constitute FRP the mat formation paving steel bridge deck structure of middle level, the heterogeneous three layer construction form in asphalt concrete pavement upper strata of lower floor, epoxy gravel of mating formation.The mat formation form of structure of lower floor of FRP is glass fiber (GF) and carbon fiber (CF) reinforced epoxy (ER) and bonding FRP solid slab or the hollowcore slab structure that is connected on the steel bridge deck; The mat formation form of structure in middle level of epoxy gravel is for ER mixes and stirs granite, basalt gravel mat formation the solid slab structure in the lower floor of compacting and the bonding FRP of being connected that paves of gathering materials; The form of structure on asphalt concrete pavement upper strata is the solid slab structure of bituminous mixture laying compacting on epoxy gravel is mated formation the middle level of routine.The mat formation interface connected mode of lower floor and steel bridge deck of FRP, boundary layer is had the bonding of structural re-enforcement be connected for the matrix resin ER of FRP material and steel have inter-molecular attraction and FRP material fortifying fibre GF, CF, guarantee the two interfacial structure one and stressed survivable.FRP the mat formation interface connected mode in middle level of lower floor and epoxy gravel of mating formation, be identical being connected certainly and the bonding connection of exasperate of the two rough interfaces of the two material matrix resin, the interface bonding strength that guarantees the two is not less than the mat formation interface bonding strength of lower floor and steel bridge deck of FRP, thereby provides firm durable mat formation bearing layer and power transmission layer for the asphalt concrete pavement upper strata.The mat formation interface connected mode on middle level and asphalt concrete pavement upper strata of epoxy gravel, for the bituminous mixture on asphalt concrete pavement upper strata embeds mat formation space between the gravel in middle level and bond the biting connecions interface that gravel constitutes and connect of epoxy gravel, guarantee that the area that is connected that the two interface connects by its firm gravel basic unit and increase is strengthened, thereby significantly improve the interface shear strength on asphalt concrete pavement upper strata.
(4) beneficial effect
FRP-epoxy gravel-bituminous concrete paving steel bridge deck new construction has following beneficial effect:
1. form of structure is more reasonable
FRP-epoxy gravel-bituminous concrete paving steel bridge deck new construction is a heterogeneous three layer construction worthy of the name, establishes adhesive linkage between each layer no longer in addition, does not also need the water layer of setting up defences in addition again on the steel bridge deck.The FRP lower floor of mating formation is the following bearing layer and the rigidity transition zone of paving structure, is again the waterproofing course and the adhesive linkage of steel bridge deck; The epoxy gravel middle level of mating formation, be the middle bearing layer and the rigidity transition zone of paving structure, the interface that is the asphalt concrete pavement upper strata again connects enhancement layer and construction high temperature buffer layer, thereby the form of structure that makes paving structure is simpler and more reasonable, and makes each layer of paving structure can both be with the length of its material property.
2. structure function is more perfect
FRP-epoxy gravel-bituminous concrete paving steel bridge deck new construction, one can utilize FRP mat formation the light material advantage and the special structure form of lower floor, alleviate dead load (the bituminous concrete paving steel bridge deck that for example 60mm is thick of paving steel bridge deck, the FRP hollow slab type lower floor of mating formation is replaced by in the lower floor of mating formation that its 30mm is thick, can make paving structure loss of weight about 1/3); Two can utilize the FRP overall structure that high-strength, long-acting interface connects and composes between lower floor and steel bridge deck of mating formation, (the FRP hollow slab type that for example 30mm the is thick lower floor of mating formation can increase the direction across bridge bending rigidity about 50% of the thick steel bridge deck of 12mm to increase the rigidity of steel bridge deck, be equivalent to increase indirectly the about 3mm of steel bridge deck thickness), reduce the deflection deformation and the amplitude of steel bridge deck; Three can be by mat formation self high powerful feature of lower floor and to the rigidity contribution of whole paving structure of FRP, on the interface of neutral axis that makes the cross section of mating formation under the prerequisite of self not destroying earlier and asphalt concrete pavement layer, move, thereby reduce the stress of steel bridge deck and asphalt concrete layer and distortion (25mm asphalt concrete pavement upper strata+7mm epoxy gravel middle level+25mmFRP hollow slab type thick steel bridge deck paving structure of lower floor+12mm of mating formation of mating formation for example, with respect to the thick steel bridge deck paving structure of the thick asphalt concrete pavement layer+12mm of 57mm, it is about 15% that the maximum of steel bridge deck reduces, and asphalt concrete pavement layer interface shear stress reduces about 30%); Four can mat formation by FRP, and subsurface material is anti-to rupture, tired and acidproof, alkali, the salt medium corrosion is better than steel and bituminous concrete, waterproof, adhesive effect is better than existing paving steel bridge deck structure, and all are bonding, waterproofing materials, can be in-30～70 ℃ of scopes operate as normal, the excellent properties of aging life-span 〉=40 year, increase the durability of new paving structure, guaranteeing that FRP mats formation application life of lower floor is not less than 30 years, epoxy gravel is mated formation and application life in middle level is not less than 15 years, be not less than 10 years the application life on asphalt concrete pavement upper strata, thereby make the structure function of paving steel bridge deck structure more perfect, the technological progress and the great development that bring the paving steel bridge deck engineering to use.
