PURPOSE: To ensure the protection and greening of a face of slope by laying a netted member on the slope ground, providing a triangular sectional slope frame in grid or rhomb thereon, and preventing a vegetation layer from being eroded by the flowing water overflowing the slope frame.

CONSTITUTION: A netted member 8 consisting of binding iron wire is laid on a face of slope 1, and reinforcements 3 and triangular sectional coil bars 4 for forming a slope frame 6 are also arranged on and fixed to the face of slope 1 by anchors 5. A molding material such as mortar or concrete is sprayed onto the frame to form the triangular sectional slope frame 6, and a greening base consisting of the soil containing seeds is sprayed to the part surrounded by the slope frame 6 to form a vegetation layer 7. When the vegetation layer 7 is thickened, the part of the slope frame visually confirmable from the outside is narrowed to enhance the beautiful appearance of the face of slope, water is prevented from being collected therein, and the vegetation layer 7 is also prevented from being eroded by the water overflowing the slope frame. Thus, the protection and greening of the face of slope can be efficiently performed.
