A rapid repair method for concrete road surface cracks

Abstract

The invention provides a concrete road pavement crack quick repairing method which comprises a stepping mechanism, a pouring mechanism and a crushing mechanism, the crushing mechanism is installed onthe stepping mechanism, the pouring mechanism is arranged right behind the crushing mechanism, and the pouring mechanism is installed on the stepping mechanism; the problems that in the using processof a concrete road, pits are formed in the road surface due to damage caused by long-term rolling compaction of vehicles, and local transverse and longitudinal cracks, missing edges and falling corners occur to many road sections, so that the road surface driving comfort and safety are seriously affected, and the road surface needs to be repaired are solved; however, when the existing concrete highway pavement is repaired; generally, new concrete is manually stirred on site, then the new concrete is directly poured into a pit slot, and the pavement is leveled to finish repairing, so that the mode has the defects of long construction time, low bonding force to the original cement concrete, easiness in falling, high manual labor intensity, low efficiency and high construction cost.

Description

Technical field [0001] The invention relates to the technical field of cement concrete pavement maintenance, in particular to a method for quickly repairing cracks on concrete road pavements. Background technique [0002] Cement concrete pavement refers to the pavement with cement concrete as the main material as the surface layer, referred to as concrete pavement. As one of the important forms of high-grade pavement, cement concrete pavement is more and more widely used. Cement concrete pavement has the advantages of high strength, strong adaptability, durability and low maintenance cost. [0003] During the use of concrete roads, the long-term rolling of vehicles will cause damage to the road surface and potholes. Many road sections have local horizontal and longitudinal cracks, missing edges and corners, which seriously affect the comfort and safety of road traffic. Repair the pavement; however, when the existing concrete road pavement is repaired, it is usually done by manuall...

Problems solved by technology

[0003] During the use of concrete roads, the long-term rolling of vehicles will cause damage to the road surface, resulting in potholes, and many road sections have local transverse and longitudinal cracks, missing edges and corners and other damages, which seriously affect the driving comfort and safety of the road surface. Repair the pavement; however, when the existing concrete road pavement is repaired, the new concrete is usually manually mixed on site, and then the newly poured concrete is directly poured into the pit, and then the surface and the pavement are smoothed to complete. Repair, this method has a long construction time, low adhesion to the original cement concrete and easy to fall off, and the labor intensity is high, the efficiency is low, and the construction cost is high;
