付けることを特徴とするセグメントの接合方法。1. A method for joining plate-shaped segments constituting a tunnel wall or the like to each other by aligning the joining surfaces of one first segment with the joining surfaces of the other second segment. , A through hole extending in the joining direction is formed in each segment, and a recess is formed around the opening of the through hole in the surface to be joined, and the male screw portion is formed on one end side and the male screw portion is formed on the other end side. Conforms to
Further, female threads having a diameter larger than that of the through hole and engageable with the bottom of the recess are inserted through the first bolts, respectively, from the surface to be joined of the first segment, from the male threaded portion. The male screw part is penetrated through the hole, the male screw part is projected from the joint surface, and the female screw part is housed in the recess. Then, the end of the female screw part of the first bolt is tapered toward the joint surface. A guide member that opens in a circular shape is attached, and thereafter, the joint surface of the second segment is aligned with the joint surface of the first segment, and both through holes are made to substantially coaxially coincide with each other. From the surface to be joined of the segment,
A second bolt similar to the first bolt is passed through the through hole, and the male thread portion of the second bolt is engaged with the bottom portion of the recess of the second segment, and the male thread portion thereof is A method for joining segments, comprising screwing the female thread portion of the first bolt through a guide member.
