A kind of road bridge crack repairing device and repairing method

Abstract

The invention relates to a road bridge crack repairing device which comprises a first connecting part, wherein the first connecting part is arranged inside a crack cleaning pit; the first connecting part is a semicircular cylinder; the convex surface of the semicircular cylinder faces upwards; a plurality of mounting holes I are uniformly formed in an arc-shaped surface of the semicircular cylinder; the mounting holes I are internally provided with first nails which are connected with an old concrete layer; second connecting parts are arranged above the first connecting parts; a plurality of mounting holes II are arranged in the middle of the second connecting parts; the mounting holes II are internally provided with sunk screws connected with the first connecting parts; a protection layeris arranged above the second connecting parts; the protection layer comprises an iron wire net piece layer fixed with the second connecting parts; a carbon fiber cloth layer is arranged above the iron wire net piece layer; a waterproof layer is arranged above the carbon fiber cloth layer; a surface layer is arranged above the waterproof layer. On premise that no new pavement is laid, the road bridge crack repairing device is capable of effectively completing reinforcement and repairing of cracks, and is reasonable in structure, short in construction time, low in investment cost, good in repairing effect, good in practicability and worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of crack repair, and in particular relates to a road bridge crack repair device and a repair method. 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.
