Maintenance Robotics in TBM Tunnelling

Abstract

Among the various domains of the construction sector, tunnelling exhibits its own specificities in particular in terms of risks. Several techniques have been developed through the years in order to make excavation works more efficient and safer. Tunnel Boring Machines (TBM) were invented some 60 years ago and the concept since went through several significant improvements that have nowadays made them the preferred approach for the vast majority of tunnel projects, whether in hard rock or in soft ground.
