Polymer Concrete Segmental Tunnel Lining System

Concrete segmental Tunnel Lining is a method of constructing tunnels using precast concrete segments. These segments are manufactured off-site and then transported to the tunnel site, where they are assembled to form the tunnel lining.

The Tunnel Steel Ring is typically made of high-strength reinforced concrete and are designed to interlock with each other to form a continuous lining. They are usually in the shape of an arch or a circle, depending on the shape of the tunnel.

The construction process begins with the excavation of the tunnel using traditional methods such as drilling and blasting or mechanical excavation. Once the tunnel is excavated, a temporary support system is installed to stabilize the surrounding ground.

The precast concrete segments are then transported to the tunnel site and lifted into place using cranes or other lifting equipment. The Construction Formwork is carefully aligned and connected to each other using steel bolts or other fastening systems.

product feature:
