Problems solved by technology

After the crack occurs, the strength of the damaged part will be reduced, the load-bearing capacity will be greatly reduced, and it will be more likely to be eroded by rainwater. If the crack is not treated, the damage will continue to expand, and eventually the road or bridge will need to be overhauled or even scrapped. Serious also cause the bridge to collapse
[0003] The existing road and bridge crack repair methods are complex in operation, low in automation, low in repair efficiency, and poor in repair strength. Therefore, we propose a road and bridge crack repair method to solve the above problems

Embodiment 1

[0053] see Figure 1-7 , a road bridge crack repair method specifically comprises the following steps:

[0054] S1. Install the flexible track 1 symmetrically on both sides of the crack 3, so that the two flexible tracks 1 and the crack 3 are parallel and equidistant, and use waterproof structural glue to seal the two ends and sides of the flexible track 1, so that the two The flexible track 1 forms an airtight enclosure structure with the bridge base 2, and the track trolley 4 is installed on the flexible track 1. The track trolley 4 is equipped with a drilling device 6, a slotting device 7, a high-pressure washing device 71 and a suction Dust device 72;

[0055] S2, using the dust suction device 72 to absorb the sundries in the crack 3, and then using the high-pressure washing device 71 to wash the crack 3 on the bridge base 2;

[0056] S3. Inject corrosive agents into the dried cracks 3 to corrode the inner walls of the cracks 3, and use the high-pressure washing device 7...

Abstract

The invention discloses a road and bridge crack repairing method, and belongs to the field of road bridges, the road bridge crack repairing method specifically comprises the following steps: S1, flexible rails are symmetrically installed on two sides of a crack; s2, a dust suction device is used for adsorbing sundries in the crack, and then a high-pressure flushing device is used for flushing the crack on the base plane of the bridge; s3, a corrosion agent is injected into the dried crack, and secondary flushing is carried out; s4, a counterbore is drilled, and a mounting groove is formed; s5, connecting pieces are mounted in the mounting groove, and connecting bolts are mounted in the counterbore; s6, a crack repairing material is injected into the crack and dried; and S7, the flexible rails are dismantled, the foundation trench is ground out, a surface protection layer is filled, and after tamping, the surface protection layer is ground to be flush with the bridge base plane. The method is easy to operate, rapid in crack repairing and firm in connection, effectively avoids the possibility of secondary cracking of the crack, has market prospects and is suitable for popularization.

Description

technical field [0001] The invention relates to the field of road bridges, more specifically, to a method for repairing cracks in road bridges. Background technique [0002] In the construction of roads and bridges, cracks are easy to appear. Common cracks are divided into structural cracks and non-structural cracks. Structural cracks can be divided into design structural cracks and construction structural cracks, and non-structural cracks are divided into plastic cracks. , temperature difference cracks, long-term dry cracks, tortoise cracks and other aggressive cracks. After the crack occurs, the strength of the damaged part will be reduced, the load-bearing capacity will be greatly reduced, and it will be more likely to be eroded by rainwater. If the crack is not treated, the damage will continue to expand, and eventually the road or bridge will need to be overhauled or even scrapped. Serious It can also cause bridges to collapse. [0003] The existing road and bridge cr...
