METHOD FOR LINING TUNNEL, BAG BODY FOR TUNNEL LINING AND ITS TUNNEL LINING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a lining technique for a tunnel capable of simply lining the tunnel, preventing a displacement in the longitudinal direction of the tunnel of a tunnel supporter as a timbering arranged along the internal surface of the tunnel and capable of stably supporting the interior wall of the tunnel.;SOLUTION: Band-shaped bag bodies 10 having a predetermined length are arranged along the internal surface of the tunnel T while a pressure fluid is injected into the bag bodies 10 and brought into close contact with the internal surface of the tunnel T. The pressure fluid is discharged from the bag bodies 10, maintaining the internal pressure of the bag bodies 10, and a fluid solidifying material 11 is injected into the bag bodies 10. The bag bodies 10, in which the solidifying material 11 is injected, are brought into close contact with surely on the internal surface of the tunnel T by solidifying the solidifying material 11 in the bag bodies 10, and the tunnel T is supported stably.;COPYRIGHT: (C)2005,JPO&NCIPI
