Shield mud treatment system

Shield non-excavation mud purification and treatment system is a kind of mud purification and treatment machinery developed for treating the retaining wall mud used in non-excavation project construction. The shield machine excavation has mechanical and hydraulic ballast discharge methods, with hydraulic type being the majority. The hydraulic shield has a sealing chamber filled with bentonite fluid at the working face. The bentonite fluid is used both for balancing earth pressure and groundwater pressure and as a medium for conveying the discharged soil. Therefore, there are high requirements for mud treatment. based on years of design and production experience, GREEN has developed its own shield mud treatment system, which can fully meet the technical requirements of shield construction.

The mud and water treatment system for shield structure produced by GREEN has the following characteristics.
1. The system equipment contains mud tank, drilling fluid shale shaker, mud cleaner and jet mixing device. This system has three major functions of grading and purifying mud, configuring mud and conveying mud. The system can provide the mud required for excavation construction to the closed chamber of excavation surface in time. The specific gravity, viscosity and other technical indexes of the mud prepared by this system with high quality bentonite can meet the requirements of forming mud film and stabilizing excavation surface in high permeability sand layer.
2、The shield non-excavation mud purification and treatment system can separate and treat the mixed mud formed by cutting soil and sand transported to the ground in time, and then adjust the recovered mud for use.
