<P>PROBLEM TO BE SOLVED: To construct a sufficiently load-resistant reinforcing layer without lessening the hollow section, namely by using only a thin thickness when an existing lining concrete of a tunnel deteriotates and cracks or the like generates. <P>SOLUTION: In the tunnel reinforcing construction method, when reinforcing a tunnel lining concrete, the surface of the lining concrete is covered with steel sheets or the surface of the lining concrete is internally wound with steel wires in mutual distances and a crack dispersion type fiber reinforced cement composite material is sprayed thereon. <P>COPYRIGHT: (C)2004,JPO |
