METHOD AND DEVICE FOR NONDESTRUCTIVE INSPECTION OF TUNNEL LINING CONCRETE

摘要

PROBLEM TO BE SOLVED: To provide a method and device for nondestructive inspection of tunnel lining concrete by which the automation of inspections and shortening of inspection time can be realized though they are in a dilemma.;SOLUTION: In the method for nondestructive inspection of tunnel lining concrete, the concrete lining a tunnel is inspected by moving robot running rails to an arbitrary position in the circumferential or transversal direction of the tunnel by extending or contracting and inclining an expansion timber provided on a traveling lorry and temporarily fixing the rails on the surface of the concrete. Then the concrete is inspected by repeatedly running or running and stopping an inspection robot in the longitudinal direction (axial direction) of the tunnel on the rails.;COPYRIGHT: (C)2002,JPO
