What is an Earth Pressure Balance (EPB) Tunnel Boring Machine?
26-04-2022EPB TBMs control the stability of the tunnel face and subsidence of the ground surface by monitoring and adjusting the pressure inside the cutterhead chamber to achieve a balance with the water and ground pressure in front of the cutterhead, hence the name 'pressure balance'. The way these machines operate is called 'close mode
