Shield tunneling machines joysticks

The slurry-type shield tunneling machine joysticks machine excavates ground while preventing the face from collapsing by using the pressure of circulated muddy water in the cutter chamber. Excavated soil material is transported as fluid slurry to the slurry treatment plant and separated into muddy water and soil. This shield tunneling method excavator joysticks can be applied to large-diameter tunnels and high-water-bearing tunnels, and is suitable for use in severe working conditions such as tunneling under the sea or rivers.
