Description

Technical Field

[0001] The present invention relates to the technical field of wall repair, in particular to a concrete wall repair device. Background Art

[0002] During the use of a building, due to various reasons, concrete walls often develop cracks or serious damage. These cracks and damage not only affect the appearance, but can also cause water seepage, further widening the cracks and ultimately affecting the wall structure. Therefore, cracks and damage need to be repaired immediately. Concrete wall repair differs from other wall repairs. For small and irregular cracks, adhesion is poor. Therefore, the cracks must first be trimmed, followed by cleaning the wall surface, and finally refilling with concrete, which is then smoothed to complete the repair. Existing wall repair devices generally simply fill the cracks and cannot guarantee smoothness and adhesion after repair. Furthermore, they cannot achieve fully automatic concrete wall repair, resulting in a poor degree of automation. Summary of the Invention
