  A Soil TBM Based on Hydro-Excavation and Extruded Lining

  Abstract: There is plenty of room to enhance the current soil Tunnel Boring Machines (TBMs). The present article introduces a novel semi-mechanized tunneling method for soil excavation that uses high-pressure waterjets and concrete extrusion. Compared to conventional excavation tools (fracture, friction and wear), hydro-excavation has a higher power-to-weight ratio, faster advance rates and lower wearing...
