The development of mechanized excavation systems with TBM for the realization of tunnels prompts an increasing use of precast segments to support the vault. Since 1991 AWM has been developing and constantly improving an automatic system for the production of such segments through manufacture of equipment ensuring high productivity and consistent quality. Of critical importance within the set up of the precast segments is the efficient production of reinforcement cages resulting from the assembly of diverse electrowelded elements pieced together; when properly planned, this step can grant large cost savings and therefore increase competitiveness.
For over 20 years, AWM has been building automatic equipment for the production of electrowelded curved elements used as reinforcement in tunnel segments.
Thanks to an experience evolved on the most important construction sites around the world, AWM gives a global solution to the requirements of the underground construction industry, starting with the technical consulting service during design phase and continuing with a full set of machines for the manufacturing of tunnel segment cages.
