Concrete is a very important structural material in engineering buildings and it is of great significance and practical value to visually describe the internal components and defects of concrete structures by means of imaging. In this paper, a three dimensional imaging detection technology for concrete has been introduced, which employs special techniques such as point contact, dry coupling, array and shear wave observation, and the result of the test block experiment and engineering practice shows that this method can accurately detect abnormal parts of steel bar and void in steel fiber reinforced concrete.
