Description

Road crack repairing device and method

Technical Field

The application relates to the technical field of road construction, in particular to a road crack repairing device and a repairing method.

Background

At present, pavement layers of structures such as roads, basketball courts, parking lots and the like are easy to crack under the comprehensive action of conditions such as climate, load, material self factors and the like. In cold areas or areas with large temperature difference between day and night, even if roads are newly built, the pavement is easy to shrink and crack within 1-2 years of use. In China, a semi-rigid base asphalt pavement is the most commonly applied road structure type, and besides thermal shrinkage cracking, reflective crack diseases caused by thermal shrinkage and dry shrinkage characteristics of the semi-rigid base are particularly common. The surface cracking not only affects the road aesthetic property, integrity and driving comfort, but also induces more serious structural damage under the action of factors such as water temperature, driving load and the like. For example, after the asphalt pavement cracks, rainwater can penetrate into the pavement structure along the cracks, so that asphalt and stone are peeled off, the rigidity of the base material is reduced, the pavement is damaged by loosening, pot holes, mud pumping, sinking and the like, and the service life of the pavement is shortened. If the crack is not repaired in time or the means is improper, the crack can be rapidly expanded, and the service life attenuation is accelerated, so that the proper crack repairing measures are adopted, and the method has practical significance for guaranteeing the integrity of the road structure and prolonging the service life of the road.

The prior patent grant publication number: CN108660950B discloses a road and bridge crack repair fixing device, including the crack, the inside recess intussuseption of crack is filled with the concrete layer, the top of concrete layer is equipped with the chisel hair layer, the cement mortar layer has been laid at the top of chisel hair layer, the cement concrete layer has been laid at the top of cement mortar layer, steel sheet layer has been laid in the inside groove at recess top, the steel sheet layer is located the top of cement concrete layer, be equipped with first epoxy waterproof layer between steel sheet layer and the cement concrete layer, the periphery of steel sheet layer is equipped with fixing device, the fixed spiro union in top of steel sheet layer has a plurality of inverted T-shaped roof beams, it has three-layer reinforcing bar net to alternate between the inverted T-shaped roof beam, the top of steel sheet layer just is located the steel bar net and is poured in and is equipped with the epoxy mortar layer, waterproof layer and bituminous paving in proper order from bottom to top of epoxy mortar layer.

The above related technical solutions have the following drawbacks: when the road crack appears, the multistage crack of variation in size can appear usually in same section road, need a plurality of constructors to carry a large amount of instruments when restoreing usually to restore, and is very troublesome.
