のである。The present invention was made in order to solve the above-mentioned conventional problems, and its purpose is particularly to green steep slopes and rock slopes that are easily subject to weathering erosion and cause slope failure, A slope that not only improves the landscape but also forms stable soil clods and has excellent water retention properties [Structure of the invention]. The slope greening method of the present invention is a slope greening method in which bearing plates are appropriately arranged and fixed on a steep slope.
A vegetation base fixing member such as a wire mesh or net, which has a receiving part attached first or later, is stretched, and the receiving part is placed on the upper side, lower side and/or middle part of the bearing plate, and various types of It is characterized by intentionally forming a thick base for plant growth by fixing the vegetation base material, and preventing the surface from collapsing even on steep slopes with good vegetation.
