@tunnel.engineering: Tunnel segments vacuum testing in the factory. As the TBM advances, it excavates the tunnel while simultaneously erecting the tunnel lining. The vacuum erector system in the tunnel utilises suction to lift precast concrete segments into position, precisely fitting them together to form the tunnel's circumference. These segments are typically designed with interlocking mechanisms or gaskets to ensure a tight seal, providing structural integrity and preventing water or soil intrusion into the tunnel. The vacuum erector carefully positions each segment in sequence, guided by the TBM's advance and the tunnel's curvature, creating a secure and durable tunnel lining as the machine progresses through the subsurface environment.
