Rock tunnel boring machines

Rock tunnel boring machines progress through hard rocks without need for confinement. Nevertheless, on some sites the filling of the annular gap requires the use of a suitable tail seal grease. Protection of the main bearing, hydraulics and boring additives are also essential to the correct operation of the tunnel boring machine.
