DEVICE FOR PROBING LINING OF CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To move an inspecting device for probing defects which possibly have occurred in the back surfaces of a concrete structure as bringing it into close and parallel contact with the concrete structure under a predetermined pressure. SOLUTION: This lining probing device is composed of a moving carriage 1 which travels along a concrete structure T, a detector 9 to be moved along the concrete structure T as being pressed against a surface to be probed (t) of the concrete structure T to detect defects present in the back of the concrete structure T, and a holding device H mounted on the moving carriage 1 to hold and bring the detector 9 into contact with the surface to be probed (t) during the measurement of the surface to be probed (t).
