PURPOSE:To easily construct a sheathing work by assembling by a method in which netting materials produced in factory are assembled through spiral steel wires to form a cage, and sheathing packed with a water permeable sheet, soil, and stones is set in the cage on a slope. CONSTITUTION:A cage 1 is made up of a netting material 5 having bottom and four side faces which are welded at contacts with spiral steel wires arranged vertically, laterally, and slantly. In the cage 1, each face of the bottom and four sides is folded and combined through the spiral steel wires 6. A sloped ground is partly cut off to form a flat land, the cage 1 is set on the flat land, and a water permeable sheet 2 is laid on the inside valley side and bottom of the cage 1 at least. Soil 3 and stones 4 are packed into the cage 1 to form sheathing for the slope. In this case, the sheet 2 used contains plant seeds and fertilizer and the soil 3 contains fertilizer. The sheathing can thus be easily assembled for construction. |
