Slurry treatment plant

  • The shield method is a construction method for tunneling under the ground using a shield machine.
  • We are offering a slurry treatment plant for a slurry shield method, which is one type of shield method.
  • What is the shield method?
    A steel frame called a shield machine drives through the ground to excavate tunnel segments and make a main tunnel at the same time by combining those segments.
    What is the slurry shield method?
    The surface of the tunnel excavated by a shield machine is stabilized with pressurized slurry. The sand and slurry is transferred to the ground surface through a pipe. Then the sand and slurry is separated. The sand is collected and the slurry is used again.

Slurry Treatment Plant

Main equipment

1. Vibrating screen
A device to dehydrate and separate solid matter from mud (gravel and sand) produced during various types of construction.
2. Filter press
A device that pressurizes and dehydrates mud produced during construction in order to separate solids and liquids.
3. Agitating tank
A tank that contains mud produced during construction with an agitator in it that prevents the deposition of solids.
4. Waste water treatment device
A device that adjusts the pH and turbidity of muddy water produced during various types of construction in order to satisfy discharge standards.
