By the way, considering the purpose of use of the shield tunnel (1), when joining the constituent segments (2),
The joints must be in close contact and have a structure that prevents water from entering from the outside. For this reason, each segment (2) requires high dimensional accuracy.For example, the flatness of both ends! -t

Therefore, even if strict dimensional accuracy is required, such as for the shield tunnel segment (2), as long as conventional manufacturing methods are used, the manufacturing accuracy of the outer box cannot meet this requirement due to distortion and deformation during welding. However, in order to maintain the required accuracy, the outer box (2a) of the VC needs to be mechanically finished before or after filling with concrete, resulting in high costs.
