PURPOSE: A fiber reinforced synthetic resin spray device is provided to use for a reinforced concrete beam or column and a lining structure of a tunnel effectively. CONSTITUTION: The fiber reinforced synthetic resin spray device contains: a synthetic resin sprayer(20) provided with a resin supplier(21) for supplying resins to reinforce a reinforced concrete structure(100), a hardener supplier(22) for supplying hardener to harden the resins, a mixer(23) for mixing the resins and the hardener mutually, and an injection nozzle(24) for spraying the mixed synthetic resins to a reinforcement plane of the reinforced concrete structure(100); a composite fiber supplier(10) for reinforcement provided with a fiber advancer(13) for advancing composite fibers for reinforcement forward to reinforce the reinforced concrete structure(100), a cutter(14) cutting off the strands of composite fibers(12) which advances using the fiber advancer(13), and a composite fiber discharger(15) for supplying composite fibers for reinforcement toward an injection nozzle of the synthetic resin sprayer(20), wherein the composite fibers discharged through the composite resin discharger(15) of the composite fiber supplier(10) for reinforcement are mixed with synthetic resins sprayed through the injection nozzle(24) of the synthetic resin sprayer(20), then attached to a reinforcement plane of the reinforced concrete structure.
