Traffic Tunnelling for efficient traffic arteries.

Machines in the large-diameter sector for inner-city and urban traffic tunnels.

By the middle of this century, the world‘s population is expected to have reached nine billion, and two thirds of these people will live in large conurbations. To keep people and goods on the move, the way ahead for new efficient infrastructures is leading underground. With state-of-the-art technologies, even in cramped and complex jobsite conditions efficient infrastructures are created exactly where they are needed. For the construction and expansion of urban metro systems Herrenknecht TBMs have built new tunnels in more than 700 projects. For the longest railway tunnel in the world under the Gotthard mountain range, machines from Herrenknecht excavated more than 85 kilometers of the 2 × 57 km long main tubes. Worldwide, construction companies have built a total of more than 2,800 kilometers of new tunnels in the diameter range > 4.20 m with Herrenknecht technology. In 2015 alone Herrenknecht supplied more than 60 large tunnel boring machines.

Utility Tunnelling for underground supply and disposal systems.

Utility Tunnelling Machines for supply and disposal tunnels.

As the world's population grows, the need for underground supply tunnels is also increasing; this is just as true for threshold and developing countries as for modern urban centers. Therefore, around 850 Utility Tunnelling Machines from Herrenknecht are in operation around the world constructing or installing water and wastewater systems, gas and oil pipelines,as well as conduits for electricity and data lines. Here, trenchless technology offers a range of advantages compared to conventional construction methods: traffic, the economy and the environment remain mostly undisturbed when micromachines, HDD rigs or shaft sinking equipment are being used.
