An Earth Pressure Balance (EPB) Tunnel Boring Machine (TBM) works by maintaining soil pressure at the tunnel face to prevent collapse and manage ground stability. It uses a rotating cutterhead to excavate soil, which is then mixed with conditioning agents to create a soil paste that balances pressure while being conveyed through screw conveyors. As the TBM advances, it simultaneously installs precast concrete segments to form the tunnel lining, ensuring structural stability. Tunnelling is vital

How does Tunnel Boring Machine (TBM) work? A Tunnel Boring Machine (TBM) is a specialised piece of equipment used to excavate tunnels through various types of soil and rock. It works by using a rotating cutter head with sharp disc cutters or tools that grind away the material in front of it, creating a tunnel of a precise diameter. As the cutter head rotates, the TBM simultaneously removes excavated material through a conveyor system and supports the newly created tunnel walls with precast concr
