Tunnelling Pocketbook 2021

For many years, the Taschenbuch für den Tunnelbau (Tunnelling Pocket Book) has been a practical guide for clients, planners and contractors, as it deals with current developments and innovative solutions to problems and thus documents the state of technology.

Mechanised tunnelling: construction of landfall sections of underwater gas pipelines by pipe jacking

Machines and equipment: DAUB recommendation for the selection of tunnel boring machines

Construction materials and components: Utilisation of excavated material from mechanised tunnelling in soft ground

Research and development: Aerodynamic aspects of modern railway tunnels

Digitalisation in tunnelling: BIM pilot project on the eastern A44 motorway tunnel chain in the German state of Hesse

Project examples: Underground turning of a hard rock shield machine in 20 days (Filder Tunnel); Undercutting of the historically protected DB Directorate in the Stuttgart 21 project.
