PROBLEM TO BE SOLVED: To provide a method for measuring the pouring depth of a repairing material to a crack, capable of pouring a repairing material for concrete into a crack part, to measure the filling action thereof, using a right-angled analyzing method of ultrasonic waves. SOLUTION: A crack 13 formed on a concrete piece 11 of a measuring object is decided to be a reference position c, and an ultrasonic transmitter 3 and an ultrasonic receiver 5 are arranged at almost equal distance from the reference position c. An ultrasonic transmitter 3 is excited from an ultrasonic treatment apparatus 9, and an electrical detection signal from the ultrasonic receiver 5 is fetched into the ultrasonic treatment apparatus 9. The waveform can be analyzed by the ultrasonic treatment apparatus 9, and the depth of the crack is obtained. Then, the ultrasonic transmitter 3 and the ultrasonic receiver 5 are arranged at a predetermined distance, based on the depth of the crack obtained from the reference position c in the measuring process. The ultrasonic transmitter 3 is excited from the ultrasonic treatment apparatus 9, and the electrical detection signal from the ultrasonic receiver 5 is fetched into the ultrasonic treatment apparatus 9. The waveform can be analyzed by the ultrasonic treatment apparatus 9, and the pouring depth of the repairing material is measured. COPYRIGHT: (C)2005,JPO&NCIPI
