Earth Pressure Balance (EPB) Tunneling

epb tunneling « home

Earth Pressure Balance (EPB) tunneling utilizes a Tunnel Boring Machine (TBM) that allows for installations in unstable ground. The ground at the cutting face is supported by “earth pressure” by balancing the advancement of the tunnel with the discharge rate of the excavated soil that is contained through a screw auger.
