Slurry TBM prevents tunnel face from collapsing by pressurized mud water in the cutter chamber. Excavated soil material is transported in fluid slurry from TBM to the slurry treatment plant, and separated into mud water and soil. Mud water is sent to the cutter chamber again, then returned with excavated soil material in slurry to the plant.
By synergistic effect of the pressurized mud water and cutter head, the stability of the tunnel face is maintained against earth pressure and groundwater pressure.
Slurry TBM can be applied to large diameter tunnels or high water pressure tunnels. Therefore, it is used under severe construction conditions such as tunneling under the sea or river.
We have a delivery record of a maximum diameter of 14.14 m TBM.<\/p>\n\n\n\n
