[0002] Concrete is an engineering composite material and one of the main materials used for road paving. After long-term use, it will cause varying degrees of damage to the concrete pavement due to the rolling of vehicles and the vibrations generated when vehicles are driving. After a period of time, the concrete pavement will crack. After such a situation occurs, the relevant staff will repair it to avoid greater damage to the concrete. At the same time, in order to avoid traffic hazards, a concrete crack repair device will be used during the repair. However, the existing concrete crack repair device still has some shortcomings. For example, it does not have the function of rapid compaction and smoothing during repair. Compacting and smoothing often requires two different structures or equipment to complete. At the same time, the concrete road repair in the tunnel cannot be effectively handled. The tunnel cannot be exposed to sunlight, resulting in the repair site cannot be quickly dried. For this reason, we propose a concrete crack repair device for tunnel construction. Utility Model Content
