PURPOSE:To form a solid slope protecting layer which is prevented from being easily exfoliated, by a method wherein an earth grain group containing seeds are injected through a gap between nozzles as liquid foaming resin is injected toward a face of slope through a number of nozzles. CONSTITUTION:An earth grain 4 group is injected through a gap between nozzles 2 of an injection pipe 3 as liquid foaming resin is injected toward a face of slope formed by a concrete layer or a hard bedrock through the injection pipe 3 formed with a number of the injections 2. In this case, the earth grain 4 group is injected to a face 1 of slope as it is entangled with a monofilament 5 group injected through the nozzles 2, and the earth grain group is present uniformly in a fiber-entangled layer in a condition in which the monofilament 5 group is entangled therewith. Seeds in the earth grain 4 held in a laminar manner on the face 1 of slope takes nourishment in the earth grain 4 for growth, and when the seeds grows into a plant, the roots thereof are entangled with the fiber of the filament 5 group. This enables formation of a solid slope protecting layer which is prevented from being easily exfoliated. |
