PROBLEM TO BE SOLVED: To lighten the weight and reduce the usage of grout when treating reinforcement with rust prevention by injecting grout therein exposed from a slope in a pressure receiving structure for use in a slope reinforcing method of inserting a single or a plurality of pressure receiving structures formed with numerous openings in a projection part which projects from the slope of the reinforcement buried in a slope such as a natural ground and an excavated ground, overlappedly inserts a pushing plate therein and anchor thereto by screwing a nut in the projection end of the reinforcement. SOLUTION: This pressure receiving structure is integrally molded into a web shape by combining annular frames 2 disposed concentrically and crosspieces disposed radially and is formed of FRP (fiberglass-reinforced plastic). After the reinforcement 6 is inserted into a drilled hole, the single or the plurality of pressure receiving structures are insertedly installed into the reinforcement 6 on the slope and a bellows-shaped cylindrical mold 8 is strongly pushed against the slope 5. After that, the grout 9 is injected in the mold and fills a hollow part around the reinforcement 6. COPYRIGHT: (C)2004,JPO&NCIPI
