Problems solved by technology
[0002] The current pavement crack repair device mainly includes a crack filling mechanism and a pressure roller mechanism for compacting the repair material in the pavement cracks after the crack filling mechanism is filled, and the crack is pretreated before the crack repair. It is mostly to clean up the impurities in the cracks. Since the cracks usually occur in the case of tearing caused by road surface settlement or cracking factors, the structure of the side edges of the cracks is usually loose, and the traditional crack repair equipment can repair cracks. The edge of the crack will not be specially treated before, so the combination between the side wall of the crack and the repair material will not be tight in the later stage, thereby retaining a small seepage gap, which will cause rainwater to seep into the subgrade from these seepage gaps in rainy days, making the The subgrade is soaked by rain, and the long-term rolling of passing vehicles will cause damage to the subgrade and cause the road surface to collapse

The invention provides a pavement crack repairing device for traffic engineering construction. The pavement crack repairing vehicle comprises a vehicle body (1), the vehicle body (1) is provided witha crack filling mechanism (22) and a pressing roller mechanism (23) used for compacting a repairing material filled in a pavement crack (11) after the crack filling mechanism (22) is filled with the repairing material, and the pavement crack repairing vehicle further comprises a milling cutter structure, a chip limiting blocking strip and a chip collecting mechanism. Before crack repairing, a milling cutter is used for milling loose parts of the edge of a crack, milled chippings are conveyed to the ground through a special structure, and meanwhile the chippings are effectively removed throughthe chipping collecting mechanism. A repaired place can be well combined with the edge of a crack, so that rainwater on the pavement is prevented from permeating into the repaired crack.
