To provide a concrete reinforcing net of chemical fibers having a shearing reinforcement effect in a concrete structure of an RC construction, in a reinforcement which is provided in concrete in order to prevent fall of concrete or separation of lining concrete in a tunnel and is provided in the concrete and made of not iron bars but a net of chemical fibers free from salt damage.
A linear chemical fiber bundle is formed by twisting a plurality of lengths of the thread-shaped chemical fiber, and the chemical fiber net is constituted by combining the chemical fiber bundles in a lattice shape. The wire diameter of the chemical fiber bundle is 1.5 mm to 5 mm, and the spacing between the lattices is 20 mm to 40 mm. The concrete reinforcing net is used as a shearing reinforcement of the concrete structure of an RC construction.
