Asphalt pavement narrow crack repair device for highway maintenance

Abstract

The invention relates to the technical field of highway maintenance, and discloses a device for repairing narrow and long cracks of asphalt pavement for highway maintenance, comprises a main body, four rollers, two pulleys, an asphalt liquefaction mechanism, a feeding bucket, two reinforcing ribs, two asphalt repair mechanisms, two negative pressure conveying mechanisms and an asphalt pressing mechanism, wherein the asphalt liquefaction mechanism is fixed in the middle of the inner bottom wall of the main body, and the feeding bucket is inserted on the top of the main body. The asphalt repairing mechanism is inserted into the interior of an elongated crack on the asphalt pavement surface through an asphalt repairing mechanism, A liquid asphalt inside the asphalt liquefy mechanism is injected into the interior of the asphalt repair mechanism by a negative pressure convey mechanism, The pressure can make the liquid asphalt fill up the inside of the narrow and long cracks completely, andthen surge upward, which ensures the integrity of the asphalt pavement, prevents the hollow inside the narrow and long cracks, and has good repairing and reinforcing effect. At the same time, the asphalt pressing mechanism effectively prevents the liquid asphalt from leaking out, and ensures the smoothness of the pavement.

Description

technical field [0001] The invention relates to the technical field of road maintenance, in particular to a repairing device for long and narrow cracks on asphalt pavement for road maintenance. Background technique [0002] After a long period of vehicle rolling on the asphalt pavement, many narrow and long cracks will appear on the pavement. If it is not repaired in time, the road will be further damaged. Crack filling is a way to maintain the asphalt pavement. It is also necessary to cut the pavement before the seam, so as to pour asphalt into the seam conveniently, but it is troublesome to carry the cutting tool, and the asphalt pavement will be damaged in a larger area during cutting, and the labor intensity will be increased. Contents of the invention [0003] (1) Solved technical problems [0004] The object of the present invention is to provide a repairing device for narrow and long cracks in asphalt pavement for highway maintenance, which is convenient to use, sa...
