It is an inclined surface that forms an angle that widens toward the outer surface of the segment. The two segments 1, 1, whose end surfaces are in contact with each other, have bent bolts 16 whose central portions are bent into an arc shape from the notch 7 to the washer 5', and the insertion holes 6', 6, 6, 6, 6, 6, 6, 6, 1, 1, 1 whose end faces are in contact with each other. 6' and insert the washer 51 in order.
Connect by tightening the nut 11 on the surface.
