PARTS FOR FORMING UNEVEN ROAD FACE

摘要

PURPOSE:To call driver's attention to road regulations by a method in which uneven lines of hard reinforcing materials are formed on flat road surface or parts of high-strength ropes are detachably attached to the road surface. CONSTITUTION:Projected plates 9 are detachably attached to asphalt or concrete road surface through fixing parts in the direction of crossing road at an adequate interval before a sign 4a on flat road surface. Concrete nails 15 with large-size washers 14 are inserted into the fitting rings 12a on both ends of a rope 12 of high-strength fibers and driven into the paved road to attach the rope 12 to the road. By giving vertical vibration to wheels, driver's attention is directed to road regulations to prevent accidents completely.
