METHOD FOR REPAIRING AND REINFORCING TUNNEL, BRIDGE, UTILITY TUNNEL, AND REINFORCED CONCRETE STRUCTURE USING LATTICE FIBER MESH AND CEMENT MATRIX AS REINFORCEMENT MATERIAL TO IMPROVE LOAD CARRYING CAPACITY AND FIRE RESISTANCE

摘要

The present invention relates to a seismic reinforcement method of a reinforced concrete structure. More specifically, the present invention relates to a method for repairing and reinforcing a tunnel, a bridge, a utility tunnel, and a reinforced concrete structure using a lattice fiber mesh and a cement matrix as a reinforcement material to improve load carrying capacity and fire resistance. A lattice fiber mesh is temporarily fixated using a temporary fixing means to a region such as a tunnel or a slab among the reinforced concrete structure, wherein the lattice fiber mesh is separated from the region by the self-weight. An anchor plate is used to reinforce the other region where concentrated stress occurs or the other region where the lattice fiber mesh is predicted to be separated. Therefore, the present invention can reinforce the reinforced concrete structure without damage to the lattice fiber mesh.;COPYRIGHT KIPO 2016
