Description
Technical field
This utility model belongs to field of engineering technology, is specifically related to the structure of a kind of concrete bridge deck rapid-maintenance.
Background technology
Concrete bridge deck pavement all occurs in that the diseases such as rut in various degree, passage, pit under the factors such as overload, heavy duty, makes normal transportation be affected.In order to reduce the impact on normal traffic, as early as possible open to traffic, the bridge floor i.e. structure of rapid-maintenance scheme with superperformance is used to be particularly important.At present, the most maintenance of concrete bridge deck and research work concentrate on the sectional repair materials such as Colophonium class, resinae, concrete, also employing fibre reinforced concrete, thin layer SMA is had to be applied in the maintenance of deck paving, but lack rapid-maintenance scheme and the structure of the pave-load layer of concrete bridge deck targetedly all the time.Patent CN203583305U it is also proposed a kind of concrete old bridge deck pavement rapid-maintenance structure stablizing graded broken stone based on emulsified asphalt, but this structure is not used to the rapid-maintenance of concrete bridge deck under overload, case of heavy load.
Utility model content
The utility model proposes the structure of a kind of concrete bridge deck rapid-maintenance, use this structure energy quickly open to traffic, this structure has excellent surface skid resistance, high and low temperature resistance and resisting fatigue cracking behavior simultaneously.
The technical solution of the utility model is achieved in that the structure of a kind of concrete bridge deck rapid-maintenance, after excavating former damaged concrete, concrete slab is laid reaction resin infiltration confining bed, laying high-strength modified-reaction resin bed on reaction resin infiltration confining bed, polymer modified asphalt SMA mixture bottom is laid on described high-strength modified-reaction resin bed, lay special bonding material layer on described polymer modified asphalt SMA mixture bottom, described special bonding material layer is laid polymer modified asphalt SMA mixture surface layer.
Further, described reaction resin infiltration confining bed is alicyclic based epoxy resin, and thickness is 0.1 ~ 0.3mm.
Further, described high-strength modified-reaction resin bed is glycidyl ether type epoxy resin, and coating thickness is 2.5mm.
Further, described polymer modified asphalt SMA mixture bottom is SMA10, and thickness is 3cm.
Further, described special bonding material layer is modified emulsifying asphalt layer, and thickness is 0.3mm.
Further, described polymer modified asphalt SMA mixture surface layer is SMA10, and thickness is 3cm.
The beneficial effects of the utility model are as follows: this utility model first uses reaction resin infiltration confining bed first effectively to close concrete surface, high-strength modified-reaction resin bed is set again, under high temperature action when bottom paves, tack coat quickly solidifies to form intensity, energy quickly open to traffic, the most high-strength modified-reaction resin bed can enter bottom 1 ~ 2cm, increase the rigidity of bottom, make it have higher rutting resistance, then special bonding material layer is laid, finally re-use laying Modified Bitumen SMA Mixture surface layer on special bonding material layer, make it have excellent surface skid resistance, high and low temperature resistance and resisting fatigue cracking behavior.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
The structure of a kind of concrete bridge deck rapid-maintenance shown in Figure 1, after excavating former damaged concrete, concrete slab 1 is laid reaction resin infiltration confining bed 2, laying high-strength modified-reaction resin bed 3 on reaction resin infiltration confining bed 2, polymer modified asphalt SMA mixture bottom 4 is laid on described high-strength modified-reaction resin bed 3, lay special bonding material layer 5 on described polymer modified asphalt SMA mixture bottom, described special bonding material layer 5 is laid polymer modified asphalt SMA mixture surface layer 6.
Further, described reaction resin infiltration confining bed 2 is alicyclic based epoxy resin, and its thickness is 0.1 ~ 0.3mm.
Further, described high-strength modified-reaction resin bed 3 is glycidyl ether type epoxy resin, and coating thickness is 2.5mm.
Further, described polymer modified asphalt SMA mixture bottom 4 is SMA10, and thickness is 3cm.
Further, described special bonding material layer 5 is modified emulsifying asphalt layer, and thickness is 0.3mm.
Further, described polymer modified asphalt SMA mixture surface layer 5 is SMA10, and thickness is 3cm.
nullThis utility model process when in use is as follows: after concrete bridge deck is destroyed，First excavate former damaged concrete，First to concrete slab 1 Shot Blasting，Reach construction depth 0.5mm，Without laitance、Dust，Then brush or spray reaction resin infiltration confining bed 2(reaction resin well known in the art，This resinoid often has excellent hardness、Intensity、Chemical resistance and temperature tolerance，Due to these characteristics，Reacting resin is such as used for preparing fibre reinforced plastics、Prepare Insulation Material and the castable of electric field、Prepare construction adhesive、Laminated material、Baking finish etc.)，Concrete，Reaction resin infiltration confining bed 2 can select alicyclic based epoxy resin，Thickness is 0.1-0.3mm，After brushing finally can naturally osmotic in concrete slab 1，So referred to as reaction resin permeates confining bed，Then brush or spray high-strength modified-reaction resin bed 3，High-strength modified-reaction resin bed 3 can select glycidyl ether type epoxy resin，Coating thickness 2.5mm，When high-strength modified-reaction resin bed 3 is not yet fully hardened，Making polymer modified asphalt SMA mixture bottom 4，Polymer modified asphalt SMA mixture bottom 4 selects SMA10，Placement thickness 3cm，Then special bonding material layer 5 is sprayed，I.e. modified emulsifying asphalt layer，Its coating thickness 0.3mm，Last making polymer modified asphalt SMA mixture surface layer 6，I.e.
