EPB Shield

EPB Shield

Earth Pressure Balance (EPB) TBM EPB TBM is a type of closed shield TBM. When boring, its cutterhead will rotate and cut through the ground. The mucks cut will enter soil chamber. When the chamber is full, the earth pressure therein will be in balance with the earth/water pressure on cut face,...

Slurry TBM

Slurry TBM

During slurry TBM tunnelling, the working face stability is achieved by pressurized slurry in excavation chamber to balance soil and water pressure on the working face, and excavated muck is transported by slurry circulation system. Slurry TBM is characterized by stabilizing working face in...
