[0002] At present, many concrete structures have been built in my country, such as concrete dams, sluice gates, pumping stations, ship locks, subway tunnels, docks and shipyards. Most of these structures (in whole or in part) are underground concealed concrete projects. On the one hand, their construction quality needs to be inspected and accepted at the end of the project. On the other hand, if these projects leak or seep during use, it is also urgent to find the crack location quickly so as to take relevant remedial measures quickly. Due to the complexity of the problem and the limitations of construction and testing technical means, conventional concrete crack detection methods are generally difficult to quickly find defects inside the structure.
