Beschreibungen

This book covers the fundamentals of tunneling machine technology: drilling, tunneling, waste removal and securing. It treats methods of rock classification for the machinery concerned as well as legal issues, using numerous example projects to reflect the state of technology, as well as problematic cases and solutions. The work is structured such that readers are led from the basics via the main functional elements of tunneling machinery to the different types of machine, together with their areas of application and equipment. The result is an overview of current developments. Close cooperation among the authors involved has created a book of equal interest to experienced tunnelers and newcomers.

About the authors: The four authors work in various areas of tunneling. Bernhard Maidl has been Professor for Civil Engineering, Tunneling and Construction at the Ruhr-Universitat in Bochum since 1974. In 1979 he founded the engineering firm Maidl und Maidl in Bochum, which is involved in many large and complex tunnel projects in Germany and abroad. Dr. Herrenknecht is the Founder and Chairman of the world's leading mechanized shield tunneling company. Leonhard Schmid is a planner of tunneling projects and manager of a Swiss engineering firm. Willy Ritz was formerly manager of a tunneling company in Switzerland and has a great deal of experience in the construction sector.
This book covers all aspects of TBM tunnelling: boring, driving, muck clearance, support, rock classification for mechanical tunnelling and also contract considerations. A multitude of example projects clarify the current state of the technology, and problem cases are discussed along with innovative solutions and special equipment. The close collaboration of expert authors has produced a work of interest to the experienced tunnel builder just as much as the newcomer to the field.
