Economic Fixing of Operating Systems for Tunnels with segmental Lining

摘要

Owing to increased requirements posed on operating technology and safety in traffic tunnels (RABT 2006 and Directive 2004/54/EC) an ever greater number of installation systems must be taken into consideration in conjunction with the inner lining.rnHalfen anchor rails have been established as a fixing system for the inner lining of traffic tunnels driven by the NATM for many years throughout the world. These are mounted on the formwork base for the carriage priortotheconcreting op-rnerations for the inner shell and then concreted in place. Comparable possibilities for use are also non-problematic for mechanically driven traffic tunnels with a reinforced concrete lining.
