MECHANIZED TUNNELING SUPPORTS

Product catalog summary

Project Overview: The document details the mechanized tunneling project for the restructuring of the Emscher River in Germany, focusing on the launch shaft for pipe jacking the Emscher canal system in Dortmund. The project is part of a larger initiative to restore the Emscher River, which had been polluted for over a century.

Key Specifications:

Location: Dortmund, Germany
Customer: Consortium Icotekne S.p.A. - Implenia AG
Contractor: Emschergenossenschaft / Lippeverband
Machine Used: V-006, VSM9000
Shaft Depth: 23 meters
Diameter: 9,000 mm
Geology: Sand, silt, clay

Technological Innovations: The project utilized Herrenknecht's VSM9000 technology, marking its premiere in Germany. This technology allows for simultaneous shaft sinking and lining, significantly reducing construction time and environmental impact.

Project Execution: The construction of the 23-meter deep starting shaft began in April 2008 and was completed in 17 working days. The VSM9000 machine demonstrated its efficiency by minimizing noise pollution and expediting the construction process.

Future Developments: The Emscher underground tunnel, a 70-kilometer sewage channel, is central to the project. Micro-tunneling machines will be used for further tunneling work. The completion of the "New Emscher Valley" is anticipated between 2020 and 2027.

Company Profile: Herrenknecht AG is a leader in mechanized tunneling technology, providing high-tech machinery for various ground conditions and diameters worldwide.
