PURPOSE:To prevent the collapse of sloped ground by avoiding the moving and run-off of soil particles by a method in which a slope frame is set on a slope, a netted sheet with large numbers of projections alternately formed on surface and back sides is set in the frame, and soil is packed into the frame. CONSTITUTION:A slope frame 5 is set on a slope, and a netted sheet 1 with large numbers of projections 2 alternately formed on the surface and back sides, having a thickness of 50-100mm. on the average, is set in the frame 5. Greens- planting work is provided on the netted sheet 1 by a spraying method with seeds. The meshes of the netted sheet 1 are provided, including the projections, on the whole surface, and the size of the meshes is enough to be passed by soil particles at least. The use of the sheet 1 prevent the run-off of soil particles because the soil particles are arrested by the projections 2 and dents, and the presence of the meshes 3 enables water to permeate into the lower part, promoting the extension of the roots of a plant downwards. |
