Description

technical field [0001] The invention relates to the technical field of concrete crack detection, in particular to a method for detecting changes in concrete cracks. Background technique [0002] Concrete is a general term for composite materials that are composed of gel material, aggregate and water in an appropriate proportion, and then hardened after a certain period of time. Concrete cracks are the physical structural changes of concrete structures due to the effects of internal and external factors, and cracks are the main reason for the reduction of the bearing capacity, durability and water resistance of concrete structures. Therefore, in the process of building construction, it is necessary to detect the changes of concrete cracks. [0003] Existing concrete cracks have less detection data during the detection process, and the position, direction, depth and width of concrete cracks cannot be fully detected, and there may also be interference data, so it is impossible...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a method for detecting changes in concrete cracks, which solves the problem that the existing concrete cracks proposed in the above background technology have less detection data during the detection process, and cannot accurately determine the location, location, and location of concrete cracks. The direction, depth and width are fully detected, and there may be interference data, which cannot fully understand the changes in concrete cracks, and it is not convenient to predict the changes in concrete
