KD series slurry treatment unit

Slurry pressurized balance shield: a partition plate is set at the front of the mechanical shield, and a mud-water tank is formed between it and the cutter head. The stability of the excavation surface is to send the mud into the mud-water tank, and use the mud on the excavation surface. An impermeable mud film is formed, and the water pressure is maintained by the tension of the mud film to balance the earth pressure and water pressure acting on the excavation surface. The excavated soil and sand are transported to the ground in the form of mud, separated by slurry treatment equipment, and the quality of the separated mud water is adjusted before being transported to the excavation surface. According to the difference in the structure of the mud tank and the control method of the mud pres
