This method can prevent the collapse and settlement of the ground injecting several stabilizers during excavation. In addition, it completed the tunnel after the excavation, segmented lining is installed repetitive from the rear part of the shield TBM. Especially, this method minimize works on the ground so there is a little noise, vibration, dust, pollution and traffic hazard. Also, It is possible to construct more curved and steep tunnel and tunneling under river, sea, buildings, etc. is made easy. Moreover, the process is repetitive, so that most of the works can be automated and easily managed.
