TUNNEL LINING INVESTIGATION SYSTEM AND VEHICLE USED FOR THE SAME

摘要

While the vehicle is running in the tunnel, the three-dimensional shape of the surface of the tunnel vent surface is measured by the optical cutting method using the photographing means mounted on the vehicle and the slit laser light transmitting means, and cracks that may lead to peeling or falling off It provides a tunnel ventilating surface survey system capable of accurately determining whether it is or not, and a vehicle used therein. In a state in which the photographing means/slit laser light transmitting means installation means is fixed at the first measurement position, the three-dimensional shape measurement result of one side of one of the measured tunnel abdominal surfaces, and the photographing means/slit laser light transmitting means installation means are In a state fixed to the second measurement position, the three-dimensional shape measurement result of the other side of the measured tunnel abdominal surface is used to process it into an image to be irradiated for irradiating the tunnel abdominal surface.
