Description

Technical Field

[0001] The utility model relates to a detection device, in particular to a civil engineering structure crack detection device, belonging to the technical field of detection devices for civil engineering structures. Background Art

[0002] Civil structures are usually structures such as columns, beams, piles, etc. in civil buildings, and are generally built with materials such as rammed earth and wood. For civil structures, since their materials are different from concrete and steel structures, it is difficult to avoid surface cracking after long-term use. Generally speaking, if the cracks only exist on the surface, it will not affect the stability of the structure. However, if they have penetrated through the beams and columns, forming cracks that penetrate the surface of the beams, they will gradually expand and spread, affecting the stability of the structure. However, in the prior art, it is necessary to use more advanced X-ray equipment to determine the direction of the cracks. The equipment is expensive and can only be afforded by some well-known ancient buildings. Therefore, further improvements are necessary. Utility Model Content
