At the same time, tunnel segments are the permanent lining structure of shield tunnels.

[0003] Patent No. CN216767399U discloses a reinforcement structure for tunnel ring segments, including a steel ring and a bracket; the steel ring is closely attached to the inner side of the tunnel and is composed of at least two circumferential arc-shaped members spliced together. Joint plates are respectively arranged at the openings at both ends of the arc-shaped members, and the arc-shaped members are connected through the joint plates; the bracket connects the steel ring and the bottom surface of the tunnel; multiple steel rings are sequentially assembled along the tunnel length direction and are connected through connecting pieces.
