TBM currently sized to match 54-in. C wall (66.5-in. OD) pipe.
Tunnel Boring Machines (TBMs) (click link for product specifications) are used to install 48 – 93-in. (1,219 – 2,362 mm) OD jacking pipe. The Series II TBM family consists of eight TBM models with common ease of operating controls. The Series II TBM has a sealed steering joint that allows for bidirectional, full articulation at the face of the bore. Its drive system uses two-speed drive motors which operate in either low-speed/high-torque or high-speed/low-torque modes. This functionality allows operators to precisely tailor cutting speeds and torque in varying geology. The operator controls steering, maintains line and grade and monitors the soil removal process from an interior control station. As soil is excavated, dirt paddles propel it onto the belt or screw conveyor for transport to the haul unit.
Carbide single bar, quad bar and sand shelves cutter heads come standard with a TBM purchase and can be changed underground as necessary. Mixed-ground disc cutter head for high compressive strength geology closed face cutter heads for unstable ground or custom cutter heads are also available.
