A steel segment made of a steel plate and a composite segment obtained by combining a steel plate and concrete are used. FIG. 10 is a perspective view of the steel segment. The steel segment 1 is composed of a joint plate 2, a main girder 3 and a skin plate 4 welded to each other. A required number of vertical ribs 5 are welded to the inner surface in an inverted J shape. In addition, a plurality of bolt holes 6 to 6 are formed for connecting to the steel segment 1 adjacent to the main girder 3 in the radial direction of the joint plate 2 in the circumferential direction of the shield tunnel. The bolts 7 are passed through the bolt holes 6 to join the steel segments 1 to 1 in the circumferential direction as shown in FIG. 11 and in the axial direction of the shield tunnel as shown in FIG. 12 to assemble the steel shell of the shield tunnel.

い。However, the conventional method of joining steel segments by bolts requires a large number of high-strength bolts, and thus the construction cost is high. In the construction of a single tunnel, an adjacent single tunnel cannot be constructed unless steel shells are first joined together to form a single tunnel. In particular, in the joining method using high-strength bolts, it takes time to tighten the bolts,
This process becomes critical and the construction period cannot be shortened.
