Typical Prefabricated Segmental Tunnel Ring

A segmental Tunnel Ring is a type of support structure used in tunnel construction. It consists of a series of precast concrete or steel segments that are bolted together to form a circular ring. These rings are then used to line the tunnel and provide structural support.

Segmental tunnel rings are typically used in soft ground tunneling, where the surrounding soil is not stable enough to support the tunnel on its own. The rings distribute the load from the surrounding soil and transfer it to the Tunnel Lining, ensuring the stability and safety of the tunnel.

The segments of a tunnel ring are designed to fit together tightly, with interlocking joints that provide strength and prevent water infiltration. The segments are usually manufactured off-site and transported to the tunnel construction site, where they are assembled and installed using specialized equipment.

Segmental tunnel rings have several advantages over other tunnel support methods. They can be quickly and easily installed, reducing construction time and costs. They also provide a high level of flexibility, allowing for adjustments and modifications during construction. Additionally, segmental tunnel rings can be used in a variety of ground conditions, making them a versatile option for tunnel projects.
