30 years of fast, safe and innovative tunnelling.

Traffic Tunnelling

In 2007, for the first time more people lived in towns than in rural areas. By 2025, the Earth's population will have grown to over 8 billion people. To ensure the mobility of both people and goods in spite of the unbroken trend towards urbanization, a new, high-performance traffic infrastructure will go underground with the aid of Herrenknecht tunnelling machines. Approximately 100 large Herrenknecht tunnel boring machines are currently at work around the world. For new, powerful traffic infrastructures.

Utility Tunnelling

As the world's population grows, so too does the need for underground supply and disposal pipes with small diameters - up to 4.20 meters. Herrenknecht Utility Tunnelling Equipment is at work around the world. Above ground, life, traffic, commerce and the environment continue undisturbed. By way of contrast with conventional construction methods, Herrenknecht Utility Tunnelling Machines, HDD rigs and shaft sinking units set the standards for safety, economic feasibility and environmental protection. Over 1,000 machines are proving this all around the world.

Exploration

The exploration of deep energy sources poses an enormous challenge. Deep drilling operations place both team and technology under extreme and permanent pressure. The required timeframes for achieving targets are tight, and the demands for human safety and the stability of the drill hole are very high. Whether the search for and utilization of new onshore and offshore energy sources is economically reasonable also depends on the efficiency of the drilling technology used. Herrenknecht delivers newly developed vertical drilling rigs for worldwide projects for the exploration of geothermal energy and oil and gas.

WORLD RECORD ALONG THE ENTIRE ROUTE. FOURTH HERRENKNECHT TBM SUCCESSFULLY COMPLETES THE LAST GOTTHARD TUNNEL SECTION.

Following final breakthrough in the western tubes, the two 57-kilometer main tubes of the Gotthard Base Tunnel are now fully driven. On March 23, 2011, miners commenced final excavation of the world's longest railway tunnel with the Herrenknecht TBM "Heidi" (diameter 9.43 m).

ALL AROUND TUNNELLING SOLUTIONS.

The need for integrated solutions is rising due to the growing requirements presented by increasingly complex and demanding underground infrastructure projects. Herenknecht provides state-of-the-art tunnelling technology as well as upon request project-specific equipment and service packages in the area of tunnel construction.
