PROBLEM TO BE SOLVED: To permit vegetation to improve an aspect with planting by forming a pressure receiving structure into a grated shape comprising longitudinal bars and lateral bars. SOLUTION: Pressure receiving structures 1, 2, 3 of large, medium and small sizes are formed in grated shape made of FRP, and measures are respectively formed in the same size. Longitudinal bars and lateral bars at the center part are cut off in cross shape. An anchor bolt 5 is fixed to the ground 4 of a face of slope, and the pressure receiving structures 1, 2, 3 are inserted at the cut-off parts in order from the larger size around a protruding part in the aligned state of the measures. Legs of the same shape and size in cross section as the measures are protrusively provided at four corners of a keep plate 6 and inserted in the pressure receiving structures 1, 2, 3 to place the keep plate 6 on the pressure receiving structures 1, 2, 3, and a box nut 7 is screwed to the projecting end of the anchor bolt 5 to fasten and fix the pressure receiving structures 1, 2, 3 to the face of slope. Rigidity can thereby be improved while reducing the weight of the pressure receiving structures 1, 2, 3, and the pressure receiving structures 1, 2, 3 can be fixed stably and firmly while improving work efficiency and an aspect.
