度が弱くなる傾向にある。However, in the above-mentioned conventional connecting structure, since the troublesome tightening work of rotating and tightening each of the nuts screwed to the plurality of connecting bolts is required, the connecting work is required. But tends to be cumbersome and time consuming. Moreover, in this conventional connecting structure, since the connecting surfaces of the adjacent segments (both segments to be connected) are simply in contact with each other, the connecting strength in the segment thickness direction without being restrained by the adjacent segments is high. Tends to weaken.

トの連結構造。1. A connecting structure of each segment constituting a segment ring used as a lining of a shield tunnel, which is formed on a connecting surface of both segments to be connected between the respective segments, and is cut in a semicircular shape. And a female connector which is attached to the connecting surface of one of the segments to be connected in a state of being half-depressed in the recess and has a substantially cylindrical cross section with a fitting hole, and the female connector. Formed in a substantially cylindrical cross-section that can be fitted into the fitting hole of the mold connector,
And a male-type connecting tool that is attached in a semi-submerged state in the recess in the connecting surface of the other segment to be connected, wherein the female-type connecting tool is parallel to the tunnel axial direction of the shield tunnel. Along with extending along the shield, it is formed into a substantially conical shape with a frusto-conical shape that narrows in the propelling direction of the shield and the outer shape of the conical bottom is the same as that of the recessed portion. The external shape is a frusto-conical shape, which is slightly larger than the fitting hole of the female-type connector so that it can be inserted into and fitted into the fitting hole of the mold-connecting member from the tunnel axial direction. It is formed in a substantially columnar shape, and when the male connector is fitted into the fitting hole of the female connector, the male connector and the female connector have connecting surfaces of both the segments. For the time being, the semicircular recess is integrated. In conjunction with fit in the formed circular hole portion, coupling structure of the segment that the male coupling is characterized in that it is configured to press the inner wall surface of the fitting hole in the female connector.
