TBM
Tunnel construction is nowadays highly mechanized. Securing work in mechanically driven tunnels through rock is mainly carried out with shotcrete. Sprayed concrete technology plays a central role as well for immediate support in the L1 zone as for ulterior support and lining in the L2 zone. Here, the different spraying systems must keep pace with the conditions set by the mechanical driving of the tunnel.
Spraying Robot with one-stage Telescoping Spraying Boom
The problem created by the laser navigation system of an existing back-up train has been solved by the one-stage telescoping boom with offset-mounted spraying head. The manipulator is guided by two elliptic half arches, thus allowing interference-free laser positioning of the TBM, also during shotcreting.

Spraying Robot with threestage Telescoping Spraying Boom and Carrier Vehicle Advance
The spraying robot is assembled using standard product system components. The three-stage telescoping boom and its spraying head are mounted on a sturdy carrier vehicle, able to travel 1000 mm in the tunnel axis. The spraying nozzle remains always operating centred in the tunnel axis.
