Getting road traffic moving
More vehicles on the roads

The number of passenger cars is increasing worldwide. The Asian countries have a major share in this trend: by 2050, it is expected that 35% of all vehicles will be driven in Asia.

The future needs infrastructures

Investments in the development of road infrastructure are increasing steadily. By 2030, around US$300 billion will be invested worldwide.

With us, tunnel construction and road traffic do not come to a standstill

Herrenknecht tunnelling technology is used to build efficient road tunnels that allow the traffic to flow on important transport routes and in major cities.

Whether in city or long-distance traffic, often direct road links are blocked by difficult topographies or urban planning obstacles. To meet the increasing demands on mobility in spite of this, state-of-the-art tunnel systems are often the best or the only solution. That's why contractors around the world use Herrenknecht technologies to create many kilometers of new road tunnels each year. Our tunnelling technology can cope with the tightest of spaces, can be used in all geologies and builds high quality tunnel structures with maximum safety within the constraints of existing topographical or urban realities. Exactly where they are needed.

We put performance on the road

Around the globe, hundreds of kilometers of tunnel tubes have already been built with our Earth Pressure Balance Shields, Mixshields and Hard Rock Machines for the expansion and new construction of underground road connections. For your project this means:

  • vast experience and expertise
  • top technology of the highest quality
  • fully-customized, innovative solutions
  • smooth progress and expert troubleshooting
  • comprehensive service on- and off-site
  • close teamwork with all project partners
  • maximum reliability from start to finish

In short: we do everything to ensure your project runs as smoothly as possible while keeping to budget and to schedule.

Example jobsite overview

Often, topographical barriers such as rivers or dense urban development restrict the flow of traffic. Herrenknecht TBMs create road and service tunnels as well as rescue and ventilation shafts with maximum safety for people, machines and structures.

1
Mixshield

The convertible Mixshield from Herrenknecht is excavating an inner-city road tunnel beneath a river. This machine type is particularly suited for complex geology and ground conditions with high water levels and high water pressures.

2
AVN

The remote-controlled AVN Micromachine is excavating a supply tunnel. The enhanced AVND technology with compressed air cushion also adapts to difficult geology and larger diameters.

3
Separation plant

Efficient and sequential processes separate and remove the excavated soil from the bentonite suspension – a mixture of water and thixotropic clay. The cleaned suspension is then retransferred back to the slurry circuit.

4
Vertical Shaft Sinking Machine VSM

The VSM is sinking a rescue or ventilation shaft for a road tunnel to be built later – safely, quickly, and precisely. The innovative VSM is also capable of working below groundwater – without complex groundwater lowering.
