シリンドリカルシエルをトンネル内に構築する。(Function) As described above, in the present invention, a plurality of cylindrical shells are formed by connecting a cylindrical shell structure with an outer chord member and an inner chord member having different lengths corresponding to the arch curvature by diagonal members. It consists of structural configuration units, and the same units are arranged so that there is a gap between adjacent same units in the tunnel.
The number of outer chord members that constitute one half of the arch is connected in parallel with pins, a waterproof and moisture-proof sheet is glued to the outer circumferential surface of each unit, and the arch legs are made into a pin structure.
Each unit is erected by pulling the other end of the erection wire connected to one end of the unit against the tunnel inner wall surface, compressing the inner chord of each unit. One side of the arch is erected via the wire, and the other half of the arch is covered with a waterproof and moisture-proof sheet on the outer peripheral surface of the cylindrical shell structure in the same manner as described above. A cylindrical shell having a waterproof and moisture-proof layer on the outer periphery is constructed within the tunnel by erecting the two arches and joining the waterproof and moisture-proof sheets of the arches on both sides and each of the arches.
