ROAD SURFACE CUTTING DEVICE AND CUTTING METHOD OF CURVED SLOPE

摘要

PROBLEM TO BE SOLVED: To cut a road surface in a shape of copying after a curved slope. ! SOLUTION: Two first cutting drums 320 arranged at a predetermined interval in a vehicle width direction and one second cutting drum 340 arranged in the vehicle width direction so as to fill up between the adjacent first cutting drums 320, are mounted on a base member 260 installed on a vehicle body bottom surface of a self-traveling vehicle. The two first cutting drums 320 can rock (tilt) in a V shape by an expansion cylinder 330 with a rotary shaft 328 positioned on the vehicle width outside as the center. The second cutting drum 340 becomes vertically movable to the base member 260 by the expansion cylinder. A road surface is cut in a shape of copying after the curved slope by properly changing a tilt angle of the first cutting drums 320 and a vertical position of the second cutting drum 340. !
