テール内で既に組立てられているセグメントに継手を介
して連結している。[Conventional technology] Conventionally, when assembling lining segments in a tunnel, segment joints (bolt joints, pin joints, a joints, hinge joints, etc.) required for the structure of the lining were used, and a shield machine was used to assemble segments for lining in a tunnel. Inside the tail, the segments are moved one by one by an assembling machine (erector), and the segments are connected via joints to the segments already assembled inside the tail.
従来のセグメント組立方法は、覆工構造において必要で
ある継手によりセグメントの組立てを行なうので、次の
問題点がある。The conventional method of assembling segments involves the following problems because the segments are assembled using joints that are necessary in the lining structure.
（１） 覆工構造を構成するために必要な継手である
ので、覆工構造が変わると継手をも変える必要があり、
そのためセグメントの組立てに支障を来たす。(1) Since the joints are necessary to configure the lining structure, it is necessary to change the joints when the lining structure changes.
This causes trouble in assembling the segments.
