Fibre Reinforced Concrete in Tunneling

You are here

In mechanized tunnelling, a TBM (Tunnel Boring Machine) installs concrete segments and is becoming a more common method in the tunnelling world.
Particularly in urban areas or geologically difficult situations, the use of a TBM is a very attractive option. Mechanized tunnelling has increased continuously for over 30 years.

Conventional tunnelling can be defined as the construction of underground openings of any shape with a cyclic construction process composed of the following key steps: 

  • excavation
  • placement of the primary support.

 When the temporary lining is fully stabilized, a permanent cast in place concrete lining can be installed to contain long-term loads, and provide durability and water tightness.
