The nondestructive inspection device and manner of the reinforced concrete structure by the electromagnetic wave

摘要

Topic The reflected wave signal from the crack and the cavity and the like of the reinforced concrete structure where the reinforcing rod was padded inside is detected more securely.Solutions The portable possible survey instrument itself to be loaded by 1 and the survey instrument itself in multiple positions on the surface of the reinforced concrete structure, 6 where reinforcing rod 9 was padded inside directing to the reinforced concrete structure and in the electromagnetic wave lighting means to be loaded 2 which irradiate the electromagnetic wave and the survey instrument, itself to possess with the signal processing means 4 which detect the defect of the reinforced concrete structure the signal treating by the reflected wave signal which is acquired by the receiving wave means 3 which acquire the reflected wave signal of the electromagnetic wave which was irradiated from the aforementioned electromagnetic wave lighting device and receiving wave means, as for receiving wave means, the survey instrumentAttendant upon the movement of the computer, the multiple reflected wave signals where position differs are acquired, signal processing means decrease the reflected wave signal component from the aforementioned reinforcing rod by adding or averages the multiple reflected wave signals where the position where it is acquired by aforementioned receiving wave means differs, detect the defect of the reinforced concrete structure.
