The present invention relates to a method to repair a corroded or worn-out pipe as time passes, comprising: a step of treating the surface to remove grinding, foreign substances, and moisture from the surface of the parts of the worn-out pipe; a step of treating primer to coat the surface of the parts requiring work, whose surface is treated, with resin; a step of lining carbon fiber to pile up carbon fiber, which is made by impregnating resin mixed with a hardening agent, on the surface of the parts requiring work treated with primer; and a step of lining glass fiber to pile up glass fiber, which is made by impregnating resin mixed with a hardening agent on the surface of the parts requiring work with carbon fiber piled up. Accordingly, the present invention relates to a method to repair a worn-out pipe by using the method to produce a carbon fiber and glass fiber-reinforced plastic pipe directly on site without needing a replacement of the pipe, which is able to prevent odor, operation stoppage during construction, and increase construction costs, to have excellent constructability, and to improve durability of the repaired pipe. |
