The present invention relates to a resin injection device for repairing and reinforcing a concrete structure and a method for the same. The resin injection device comprises: a connection pipe formed in the shape of a linear pipe with a predetermined length and open front and rear sides, wherein an injection gun for injecting a resin for reinforcing the concrete structure is connected to and mounted on the rear side of the connection pipe to be detached; a resin injection nozzle formed in the shape of the linear pipe mounted and connected to an open front end of the connection pipe to be detached and injecting the resin for reinforcement while widely diffusing the resin for reinforcement from the connection pipe to the front outer side as a resin injection hole is bored lengthwise in a linear shape on the front end; and a hot-wire housing comprising upper and lower housings covering the whole of the outer side of the upper and lower parts of the resin injection nozzle and the connection pipe by having upper and lower insertion grooves individually corresponding to the shapes of the upper part and the lower part and the length in a state in which the connection pipe and the resin injection nozzle are connected, wherein the upper housing and the lower housing are vertically assembled and hot wires heating by receiving power from the outside are individually installed inside so that the hot-wire housing increases the temperature of the connection pipe and the resin injection nozzle up to a predetermined temperature. The resin injection device for repairing and reinforcing a concrete structure smoothly injects the resin for reinforcement in winter. |
