Tunnels Using TBMs

Tunnels Using TBMs

It is common standard to use mechanised tunnels using Tunnel Boring Machines (TBMs) for the construction of underground structures, especially in urban environments. Our team of engineers has significant experience in the design and construction of mechanised tunnels, using precast concrete linings with conventional or steel fibre reinforcement and cast iron segments. To optimise tunnel segment support, we carefully assess the ground and hydrological conditions, imposed loads and segment arrangement.
Our engineers carefully consider interfaces with cut & cover structures, conventionally mined tunnels or cross passages. We are experienced in the design of tunnel openings for cross passages or adits and adopt elements like bicones and/or steel frame supports.

Our Expertise:

• Lining segmentation and specification
• Structural lining design using conventional or steel fibre reinforcement
• Permanent segment opening support
• Pipe jack, micro tunnelling and trenchless technology
