PROBLEM TO BE SOLVED: To provide technique, in which a steep-slope filling at an angle of 45 deg. or more to a horizontal plane is reinforced by an L-shaped latticed wall surface material composed of a plurality of metallic round bars, the strength of the connecting sections of both the inside of a filling body and a reinforcing net such as a net structure made of a resin is increased when the inside of the filling body is reinforced by the reinforcing net and which can be used without anxiety for a prolonged term. SOLUTION: Major arc sections bent in a major arc shape on one end sides of the L-shaped latticed wall surface materials composed of a plurality of metallic round bars 1, 1 are formed, and at least one vertical strands on the end section sides of nets made of a resin are bent among the major arc sections and arranged. Rod-shaped members are inserted in the bent sections b15 and the major arc sections, the end sections of the bent nets made of the resin are introduced in the direction separate from the upstanding-surface section sides of the wall surface materials, the vertical strands of the nets made of the resin are penetrated into the openings of the vertical strands of the opposed nets made of the resin and positioned on the reverse side faces, and other rod-shaped members C2 are inserted and connected into space sections formed of the penetrated vertical strands.
