ZÜBLIN’s specially developed Dual Mode system allows the Tunnel Boring Machine (TBM) to operate in both Earth Pressure Balance (EPB) mode and Slurry mode. These modes can be changed during a drive depending on soil conditions, which provides greater flexiblity, safety and efficiency during tunnelling operations. Using the TBM also ensures that any potential obstacles and curves in the tunnel direction will not delay tunnelling process. The TBM saves time as well as ensuring we remain on budget through innovative and efficient tunnelling solutions including Micro Tunnelling
or Segmental Tunnelling for Shore-crossings of Utility Tunnels, Water Intake Tunnels and Outlet Tunnels. We design and manufacture our own pre-cast concrete products to order, providing a complete managed tunnelling solution which delivers upon our clients’ expectations.
When compared to conventional open trenching techniques used in tunnel construction, our innovative trenchless tunnelling reduces both social and environmental impact. This technology means that, among other benefits, we can significantly reduce construction related CO2 emissions by 90%, as well as reduce the potential damage to the surface environment and existing structures. Our unique Desander process also reduces environmental impact through separating the water from the soil during the construction process in a closed circuit system. The water is then returned to the tunnelling process and is later recycled to be used again in other
areas to minimise water consumption.
