PURPOSE:To obtain exact sheathing work of sloped ground of a large inclination angle with good efficiency by a method in which the basal portion of the slope is divided into two compartments, a cage filled with stones is set in the compartment on the mountain side, and a cage filled with soil containing plant seeds, fertilizer, etc., with a sheet base is set in the compartment on the valley side. CONSTITUTION:A cage 5 is laid on a slope (a) on the road 6 side and strongly fixed with struts 7. The inside of the cage 5 is divided into a compartment 5b1 on the mountain side and a compartment 5b2 on the valley side with a partition 5a. Stones 9 are packed into the compartment 5b1 on the mountain side, and a sheet 1 is laid on the inside of the compartment 5b2 and soil 11 with leaf mold and fertilizer, etc., is packet on the sheet in the compartment 5b2. On the sheet 1 having a water permeability, plant seeds and fertilizer are dispersedly adhered. Soft sloped ground of great inclination angles can thus be surely sheathed with good efficiency. |
