PURPOSE: A reinforcement method of a hollow unit of a retaining wall using a fiber-reinforced composite is provided to effectively fill the hollow unit using waste nets for preventing the environmental contamination. CONSTITUTION: A reinforcement method of a hollow unit of a retaining wall installed at coast or riverside comprises the following steps: arranging waste nets on the bottom of the hollow unit, and spraying a polyurethane resin on the waste net for forming a reinforcing layer of a fiber-reinforced composite; forming a rubble layer on the upper side of the reinforcing layer; and repeating the formation processes of the reinforcing layer and the rubble layer until the hollow unit is completely filled.
