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 pressure, the mud shield is divided into: direct control type and indirect control type.
During the drilling process of the mud, due to the continuous entry of drilling slag into the mud, the specific gravity, viscosity and sand content of the mud change, which cannot meet the requirements of mud performance, and must be treated or purified, mainly solid-liquid Separation, the drilling slag in the mud is separated and discharged and then recycled.
There are two main methods of construction mud purification: sedimentation tank and mechanical equipment. Basically, the current mainstream mud-water construction has abandoned the use of large natural sedimentation tanks, and switched to a combination of shale shaker and cyclone equipment for construction. The KD series slurry treatment plant manufactured by KOSUN is mainly used to purify mud, complete mud recovery and solid slag treatment.
