Claims

[Scope of utility model registration request]

Segments that are assembled and used for adjacent lining in tunnel excavation, where the peripheral flanges of adjacent segments that touch each other are provided with notched grooves extending from the inner peripheral edge toward the outer peripheral side, and the contact surface with the adjacent segments. A bolt for connecting peripheral flanges of adjacent segments that are in contact with each other by being installed into the notch groove from the inner circumferential opening of the notch groove around the inner end of the notch groove on the opposite side of the notch groove. A tunnel lining segment characterized by having a convex portion that fits into a cap-shaped member.
