Conventionally, as described above, the inner diameter of the segment 9 and the tail clearance are measured by a medium, but this measurement work is performed at a high place.
It is also very dangerous because it is difficult to secure a foothold. Further, when the shield excavator becomes large, the measurement distance becomes long, but in that case, an error becomes large in the measurement by the media.
