Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete crack repair technology, and in particular to a self-repairing device for concrete cracks. Background Technology
[0002] Concrete roads, as a crucial component of modern transportation infrastructure, are widely used in urban roads, highways, airport runways, and many other fields. With their high strength, excellent wear resistance, and anti-skid properties, they provide stable and safe passage for vehicles and pedestrians. In urban traffic, concrete roads bear the daily volume of motorized and non-motorized traffic, ensuring the normal operation of the city. Concrete pavements on highways are a key support for long-distance transportation and rapid transit, playing an indispensable role in promoting regional economic exchange and development. The concrete structure of airport runways is also crucial for aviation safety, bearing the enormous loads during aircraft takeoffs and landings. It can be said that the quality and condition of concrete roads directly affect the efficiency and safety of transportation, as well as the overall economic development of society.
[0003] Currently, the detection and repair of cracks in concrete roads mostly rely on manual methods. Manual inspection requires workers to periodically patrol the road, visually inspecting for cracks. This method is not only inefficient, consuming significant manpower and time, but also prone to oversights, especially for hidden or small cracks that are difficult to detect in time. In the repair phase, manual operation is limited by the working environment and individual skill levels, resulting in slow construction speed and inconsistent quality. For example, in high temperatures, cold temperatures, or severe weather conditions, manual repair work is greatly affected, leading to delayed repairs and disruptions to the normal use of the road. Therefore, a self-healing device for concrete cracks is proposed. Utility Model Content

[0014] (III) Beneficial Effects
[0015] This utility model provides a self-healing device for concrete cracks, which has the following beneficial effects:
[0016] 1. This self-healing concrete crack device, through the setting of a drive mechanism and camera group, takes pictures of the road surface by the camera group set on one side of the vehicle body during road surface inspection. The captured data is transmitted to the image processor for analysis and processing. Finally, the analyzed data is transmitted to the PLC controller on one side.
