PURPOSE:To exactly protect the shoulder of a road by a method in which wild grass of good rootage is entangled with a net laid and fixed to the lower part of the ground of the road shoulder. CONSTITUTION:A net 1 of a synthetic fiber is laid on the lower part of the ground of the slope or shoulder of roads, dams, etc., and fixed with vinyl hooks 2. Wild grass 3 of good rootage, e.g., miscanthus, etc., is grown on the net 1 and its roots are entangled with the net 1. The protective force of the net 1 can thus last without damage, e.g., cutting down, etc., because of its high flexibility. |
