TUNNEL REPAIRING CONSTRUCTION METHOD AND TUNNEL REPAIRING PLATE

摘要

PROBLEM TO BE SOLVED: To provide a tunnel repairing construction method and a tunnel repairing plate allowing construction in a short period of time without using any large-scale installation machinery/material and production of a high-quality tunnel at a comparatively low cost. SOLUTION: This tunnel repairing plate 11 is formed of an integrally molded precast panel main body 12 having a serial cross section shape similar to that of an existing lining face in the tunnel. As a principal material for the precast panel main body 12, concrete, in which metal fiber is dispersed in a cement matrix with a flexural strength of 25 MPa or more, is used. COPYRIGHT: (C)2003,JPO
