グメント。[Claims for Utility Model Registration] (1) In tunnel lining segments that are interconnected by fastening bolts to form a cylindrical wall, the segment body is curved with a certain curvature using concrete. A tunnel configured as a main body and in which a plurality of inserts having bolt holes are buried at intervals along the joint surface near each joint surface on the front, rear, left and right sides of the inner surface of the segment main body. Lining segment. (2) The tunnel lining segment according to claim 1, which comprises an anchor bolt protruding from the inner surface of the segment body instead of the insert. (3) Tunnel lining segments that are interconnected by fastening bolts to form a cylindrical wall body are mainly composed of segment bodies that are integrally formed into an arcuate shape with a certain curvature from ductile cast iron. and a plurality of screw holes are formed at intervals along the joint surfaces near the front, rear, left, and right joint surfaces on the inner surface of the segment body. (4) In tunnel lining segments that are interconnected by fastening bolts to form a cylindrical wall, between a rectangular piece joint plate, an arcuate ring joint plate, and the ring joint plate, which are arranged opposite to each other. The main body is composed of a segment body formed by welding a skin plate to the convex outer peripheral surface of a frame assembled by welding a plurality of vertical ribs extending parallel to each other, and an inner surface of the segment body. On the inside of the rectangular piece joint plate and the arc-shaped ring joint plate on each of the front, rear, left, and right joint surfaces, anchor bolts protruding from the upper end surfaces of the joint plates are spaced apart along the joint surfaces. A tunnel lining segment characterized by multiple welded segments.
