METHOD FOR DETERMINING MOUNTING POSITION OF ILLUMINATION DEVICE IN TUNNEL AND JIG USED FOR THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for determining mounting positions by marking the mounting positions of illumination devices mounted in a tunnel, and a jig used for the method. SOLUTION: The jig is constituted of a road surface width direction measuring rod having a scale for displaying the center position of a road surface at a center in a longitudinal direction and measuring the length of the road surface in a traverse direction and a pair of vertical direction measuring rods vertically erected in the road surface at a prescribed position of the measuring rod for displaying a height position from the road surface. The jig moves in the tunnel to determine the mounting positions of illumination devices mounted to the inner wall surface of the tunnel. COPYRIGHT: (C)2010,JPO&INPIT
