PURPOSE:To increase strength by providing a space for accommodating temporarily one end of a connecting bolt in continuity to the box drawoff part of the adjoining segments to be coupled, and thereby reducing the size of the box drawoff part. CONSTITUTION:Segments 1a, 1b are laid circumferentially, and near the adjoining part box drawoff parts 2a, 2b are provided recessedly, and bolt holes 4a, 4b are arranged in a straight line for allowing bolts 3 to penetrate in the direction of their coupling side. The box drawoff part 2b of the segment 1b is peovided continuously with spaces 5 to accommodate temporarily the inserted bolt end, and the box drawoff parts 2a, 2b are situated parallel to the left and right. The length l of the bolt 3 shall be related to the length W of box drawoff part and length H of the space H as W+Hl, lW. Thereby bolt inserting work is facilitated, which also favors design of the segment.
