摘要： PROBLEM TO BE SOLVED: To surely detect a crack with a low cost.
SOLUTION: A wave transmitting surface of a wave transmitter 1 and a wave receiving surface of a receiver 2 are brought into contact with a surface 3A of a solid structure 3. The transmitter 1 and the receiver 2 are slided in the surface 3A while keeping a space (d) between the transmitting surface and the receiving surface large enough to detect a propagation lag of the wave caused by a crack 4 inside the solid structure 3. The crack 4 is detected by fluctuation of a transmitting time in the structure 3 from the transmitter 1 to the receiver 2. Preferably, the crack 4 is detected based on the fluctuation of the transmitting time and a change of an output of the receiver 2 caused by changes of reflection and damping of the wave in the crack 4. Preferably further, the solid structure 3 is formed into a concrete structure such as a concrete pile 10, and an inner surface of a boring hole 12 inside the concrete structure is made to become the surface 3A.
