Bridge repairing method

Abstract

The invention relates to a bridge repairing method, which comprises the following specific steps that: 1) polishing; 2) installing grouting pipes; 3) installing a pouring template: erecting a supporting system below a bridge, installing a supporting plate group, plugging the edge of the supporting plate group and the bridge through sealing plate groups, surrounding a pouring area by the bridge, the supporting plate group and the sealing plate groups, enabling the slurry entering ends of the grouting pipes to penetrate through one sealing plate group to be exposed, and installing vent pipes onone sealing plate group; 4) grouting: through the grouting pipes, injecting concrete slurry into the pouring area, plugging the vent pipes after the slurry flows out of the vent pipes, continuously carrying out pressure grouting on the pouring area, and finally, sealing the slurry entering ends of the grouting pipes, wherein a pressure value is 0.5-0.8MPa; and 5) carrying out form removal. By useof the method, one brand-new concrete layer is formed on the surface of the bottom end of the bridge, a bridge foundation is comprehensively repaired and reinforced, and therefore, the bridge is unlikely to be damaged again after the bridge is repaired.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a bridge repair method. Background technique [0002] When the bridge pavement is partially damaged, it will not only make the vehicle bump, but also aggravate the vibration of the bridge, resulting in cracks in the bridge. In addition, the local damage of the bridge pavement will also lead to the inflow of sediment, coupled with the erosion of high temperature weather and freezing weather , In the long run, it will seriously affect the service life of the bridge. [0003] When cracks appear on the bottom end face of the bridge, the existing repair method usually adopts scaffolding under the bridge, and repair personnel climb up the scaffold to inject repair materials into the cracks of the bridge. Although the cracks of the bridge can be repaired by this method, cracks appear again in the repaired place soon after the repair. Because the bridge is partially re...

Although the cracks of the bridge can be repaired by this method, cracks appear again soon after the repair

Because the bridge is partially repaired by this repair method, it is easy to cause peeling between the repair material at the damaged part and the bridge. Soon after use, the repair material will fall off at the repaired position and cracks will regenerate. In this way, the traditional repair The craftsmanship not only leads to poor repair effect and waste of repair cost, but also easily causes secondary damage to the bridge
