Tunnel Bolts

Segment bolts are a kind of special fasteners used by shield tunneling machines to connect and fasten their segments during tunneling. Through the connection of this type of bolt, several arched segments can be connected into a circle , So as to support the entire tunnel surface, which is also called segment bolts, or even become segment connectors, or because it is used exclusively for shield tunnels, it is called tunnel segment bolts or connectors.
