LINING CONSTRUCTION METHOD FOR TUNNEL AND CONSTRUCTION DEVICE FOR LINING TUNNEL USED IN IT

摘要

PROBLEM TO BE SOLVED: To provide a lining construction method for a tunnel for obtaining sufficient support performance of a tunnel pit wall by a cylindrical body filled with a solidifying material by moving the cylindrical body along the tunnel pit wall even when the cylindrical body having large dimensions in the direction of height is used and the diameters of natural ground of the tunnel are different. SOLUTION: After arranging a central part of the cylindrical body 1 in the vicinity of an upper face part of the tunnel pit wall, the fluidity solidifying material is poured into the cylindrical body 1 and is solidified to support the tunnel pit wall by the cylindrical body 1 filled with the solidifying material.
