<P>PROBLEM TO BE SOLVED: To provide a sheet for reinforcing concrete, which has light weight, excellent workability, high strength, high heat resistance, easy applicability to the surface of concrete, and insulation properties, and prevents concrete from causing surface scaling. <P>SOLUTION: A mesh sheet 14 for reinforcing concrete having a vertical member 16 and a horizontal member 18 is installed on the surface layer part of a tunnel structure so as to reinforce the tunnel structure. The vertical member 16 and the horizontal member 18 are formed of basalt fiber. At least a part of the vertical member 16 and the horizontal member 18 constitutes a portion embedded into the tunnel structure, and other parts constitute a portion exposed to the surface of the tunnel structure. <P>COPYRIGHT: (C)2013,JPO&INPIT |
