Example 1
The invention provides a fixing structure for repairing a crack of a road and bridge, and particularly relates to a fixing structure for repairing a crack of a road and bridge, as shown in fig. 1 to 3, in order to match implementation of the fixing structure, a plurality of groups of mounting grooves 1 are required to be symmetrically arranged on two sides of the crack of the road and bridge before repairing, and the fixing structure comprises a top reinforcing structure 2 and a bottom reinforcing structure 3. The strength of modification is improved by simultaneously reinforcing the upper part and the lower part.
Specifically, the top reinforcing structure 2 in this embodiment has a plurality of columns 21 and a plurality of tie bolts 22. Wherein, a plurality of upright posts 21 are uniformly arranged in the cracks of the road and bridge along the longitudinal direction; one end, far away from each other, of each two tensioning bolts 22 respectively penetrates through one group of mounting grooves 1, the end parts of the tensioning bolts are fixed through limiting nuts 23, and the opposite ends of the tensioning bolts are screwed through fastening nuts 24; a plurality of upright posts 21 and tension bolts 22 form a repair frame; the repairing frame and the mounting groove 1 jointly form a filling layer, and filling materials are filled in the filling layer;
the bottom reinforcing structure 3 comprises two L-shaped pretensioning plates 31 and a cushioning plate 32. The two L-shaped pre-tightening plates 31 are arranged below the crack of the road and bridge and are fixedly connected with the bottom of the road and bridge; the buffer plate 32 is erected on the two pre-tightening plates 31 and is fixedly connected with the pre-tightening plates 31 through fixing bolts 33; a plurality of upright posts 21 extend downwards and penetrate the bottom of the road and bridge crack 4 to be connected with a buffer plate 32.
Further, in this embodiment, the pretensioning plate 31 is a high-strength steel plate, which has high comprehensive mechanical properties and can resist strong pressure above. The bottom end of the upright post 21 is connected with a buffer spring 34, and the lower end of the buffer spring 34 is connected with the buffer plate 32. In the present embodiment, the buffer spring 34 is a high-strength high-pressure resistant spring having a certain diameter. Through setting up buffer spring 34, can carry out certain buffering, shift to the load pressure of restoreing the position, reduce the direct impact of load to the restoration position, the bearing capacity is strong, improves the duration that road and bridge used, increases road and bridge's life, reduces bridge restoration's frequency and economic expenditure.
Specifically, in this embodiment, the filler includes that from the bottom up sets gradually slip casting sealing layer, waterproof layer and asphalt concrete layer in the filling layer, and asphalt concrete layer and road and bridge main part top parallel and level. Wherein, the slip casting sealing layer is made of epoxy resin material. Epoxy material's viscidity is strong, can with whole filler and the original structure zonulae occludens of road bridge roof beam, cooperates the waterproof layer simultaneously and has strengthened fixed knot structure's waterproof performance greatly for the crack after the restoration can bear the erosion of the environment of pernicious, avoids the frequent expansion once more of crack.
For simple to operate, in this embodiment, the one side of mounting groove 1 far away from the road and bridge crack is the inclined plane, conveniently carries out spacing fixed to the tip of tensioning bolt 22 in the mounting groove 1 to and the work of demolising when making things convenient for the secondary maintenance.
Under general conditions, the crack is from the middle to both sides diffusion, therefore the crack in the middle of the crack is big, the thickness of road and bridge face is little, both sides are big a little, on the basis of this case this embodiment with road and bridge crack inside restoration for the symmetrical stair structure 5 of longitudinal section, all set up stand 21 on every layer of step, stand 21 top on the different layers of step all is less than 4 main part top surfaces of road and bridge for the top of repairing the position is filled by the filler, guarantees the roughness on road surface after restoreing.
In order to improve the strength of the whole structure, in the embodiment, two adjacent upright columns 21 are bound through steel wires, and the binding enables the adjacent upright columns 21 to have mutual traction force, so that the strength of the filler is enhanced.
Because crack department can not be completely integrated with original road and bridge face material after restoreing, still be impaired easily under receiving the external load effect that lasts, consequently this embodiment has still set up on the basis of above-mentioned structure and has consolidated roof 6, consolidates roof 6 and sets up in road and bridge crack top, and its top is less than 4 main part top surfaces of road and bridge, and the top of many stands 21 passes and consolidates roof 6, and asphalt concrete layer runs through the upper and lower both sides of strengthening the steel sheet. The strength of the repaired part is further improved and the service life of the road and bridge is prolonged by matching the reinforced top plate 6 with the upright posts 21 and the filler.
During construction, firstly, the installation groove 1 and the step structure 5 are excavated according to the concrete condition of cracks, then the upright posts 21, the tension bolts 22, the limiting nuts 23, the fastening nuts 24, the pre-tightening plates 31, the buffer plates 32 and the like are installed, then the formed filling layers are filled, finally the reinforced top plate 6 is installed, secondary filling is carried out, and the concrete can be put into use after air drying.
The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, and any simple modifications or equivalent substitutions of the technical solutions that can be obviously obtained by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
