PROBLEM TO BE SOLVED: To provide a greening protection device adding planar slope-face protection work such as covering net work thereto, facilitating maintenance, securing a passage in the maintenance and, unlike the fence work, not impairing the landscape.SOLUTION: The greening protection device includes: net unit groups each of which is formed by disposing first net units at prescribed intervals apart, each first net unit being formed by bending a welded wire net consisting of grids of 10×10 cm into a stepped form, to form at least two tread faces, and by mutually movably connecting the lateral direction and/or the longitudinal direction of the first net units; and first anchor pins each of which swingably fixes a side edge of each first net unit of the net unit group to the greening slope face or a slope face, the greening of which has been finished, with their positions of the centers of gravity deflected. |
