<p>The present invention relates to a method for lining a tunnel capable of simplifying construction using a fiber rod and polymer mortar instead of the conventional reinforced concrete, preventing durability from being deteriorated due to corrosion of reinforcing bar, and solving a problem of water leak of a structure using an adhesive waterproof material. The method for lining an excavated tunnel includes: (a) a step of flattening an inner wall of a tunnel excavated through shotcrete construction; (b) a step of installing a fixing member on the inner wall of the flattened tunnel; (c) a step of constructing a drain on an inner wall of a tunnel on which a fixing member is installed; (d) a step of constructing a waterproof material on a surface on which a drain is installed; (e) a step of installing a fiber rod in a lattice shape to form a surface parallel to the inner wall of the tunnel on the fixing member; and (f) a step of constructing high strength polymer mortar on the inner wall in which the fiber rods are arranged. According to the present invention, the method for lining a tunnel can prevent durability from being deteriorated due to corrosion of reinforcing bar by replacing a reinforced steel with an incorrodible fiber rod, simplify a process by performing a lining method without a mold by spray-coating polymer mortar on the fiber rod, and ensure economic feasibility by shortening construction period.</p> |
