Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and particularly relates to a structural crack detection device for construction engineering. Background Art

[0002] After construction, buildings such as houses and bridges require crack detection to prevent potential safety hazards. Cracks in concrete walls are primarily caused by the concrete itself and by factors related to the construction process. These cracks can be repaired using automatic low-pressure grouting. Automatic low-pressure grouting is a comprehensive technology developed by the Beijing Yejian Engineering Crack Treatment Center for concrete crack grouting, encompassing materials, equipment, and construction.

[0003] Ultrasonic detectors are currently widely used for crack detection. Ultrasonic waves are characterized by their high frequency, short wavelength, and excellent beam and directionality, traveling in a straight line over a certain distance. This allows for more accurate crack detection. However, existing ultrasonic detectors often have a rigid structure, making them difficult to adjust according to actual needs. Their detection height and range are limited, making them inconvenient to use. Utility Model Content
