Bentonite slurry grout plant

A bentonite slurry grout plant is designed to produce, store, and supply bentonite slurry for use in grouting applications, particularly in civil engineering, construction, and foundation projects. Bentonite slurry is a mixture of water and bentonite clay, known for its high viscosity, thixotropic properties, and ability to form a stable, impermeable barrier when hydrated.

A bentonite slurry grout plant refers to a specialized facility or system designed to produce, store, and supply bentonite slurry for use in grouting applications, particularly in civil engineering, construction, and foundation projects. Bentonite slurry is a mixture of water and bentonite clay, known for its high viscosity, thixotropic properties, and ability to form a stable, impermeable barrier when hydrated.

Applications of bentonite slurry grout plant:

Diaphragm Wall Construction: Forms a temporary or permanent cutoff wall to prevent groundwater ingress.
Pile Driving: Acts as a lubricant and stabilizer during pile installation.
Trench Cutoff Walls: Used in environmental remediation to contain contaminants.
Tunneling and Shaft Sinking: Provides support and reduces groundwater inflow.
Foundation Underpinning: Stabilizes loose soils and improves bearing capacity.

Advantages of bentonite slurry grout plant:

Self-Healing Properties: Seals minor leaks due to swelling.
High Yield Value: Maintains suspension of solids under pressure.
Environmentally Safe: Non-toxic and biodegradable in most cases.
Cost-Effective: Reduces drilling fluid losses and improves efficiency.

More Grout plant

Injection grout plant (grouting plant/grouting equipment system) is an integrated equipment system for grout preparation and injection in geotechnical engineering, construction and geological disaster management. Its core functions, technical features and application scenarios are as follows:
Core functions and equipment composition
Grout preparation system
Double-shaft mixer: adopts variable frequency speed regulation technology to achieve accurate proportioning of raw materials such as cement, water glass, bentonite, etc. (proportioning accuracy ±1%) to ensure slurry uniformity.
High-speed pulping machine: through the action of centrifugal force (speed ≥1450r/min), the powder is quickly dissolved, and the preparation efficiency is increased by 40% compared with traditional equipment, which is suitable for ultra-fine cement-based slurry.
Automatic batching system: integrated with screw conveyor, electronic scale and PLC controller to realize automatic metering and transportation of raw materials and reduce manual intervention.
High-pressure injection system
Piston pump group: adopts three-cylinder single-acting reciprocating pump (such as SGB6-10 type), with an output pressure of more than 10MPa and a flow rate of 6-10L/s, supporting single-liquid slurry and double-liquid slurry (cement-water glass) injection.
Intelligent control system: real-time monitoring of grouting pressure, flow and cumulative grouting volume, automatic generation of construction records (in compliance with GB/T 50448-2015 specifications), and support for cloud data storage and traceability.
Explosion-proof design: For high-risk environments such as coal mines, the equipment is equipped with explosion-proof motors, intrinsically safe circuits and pressure relief valves to ensure construction safety.
