Grout Plant

High-pressure borehole grouting equipment is not merely a single grouting pump but a complete system configured based on factors such as borehole depth, grout type, and operating pressure. Typical components include a high-speed grout mixer, an agitated storage tank, a high-pressure grouting pump, a pressure control unit, grouting pipelines, a flow meter, and a borehole packer.
During operation, the mixer first prepares a homogeneous grout mixture according to the design ratio. The grout is transferred to the storage tank, where it is kept under continuous agitation, before being pumped through the pipeline into the borehole. The borehole packer seals the grouting section, allowing the grout to be injected into rock fractures, soil voids, or underground cavities at the specified pressure.
Depending on project requirements, the equipment can be configured as a stationary, skid-mounted, trailer-mounted, or containerized unit to suit specific transportation and on-site setup conditions.

The Colloidal Bentonite Mixing Plant for Grouting utilizes high-speed colloidal mixing technology to rapidly disperse bentonite particles in water, producing a slurry that is fine, uniform, and suitable for pumping. This equipment can be used independently to prepare bentonite slurry or to process composite grouting materials—such as cement-bentonite mixtures—according to specific engineering formulations.
In applications such as foundation reinforcement, tunnel grouting, dam seepage control, and rock fissure treatment, the uniformity and stability of the slurry directly impact material pumpability, dispersion range, and overall grouting effectiveness. Although bentonite offers excellent suspension, lubrication, and impermeability properties, it absorbs water and swells rapidly; consequently, the use of conventional low-speed mixing equipment often leads to the formation of clumps and localized concentration inconsistencies.

High-quality slurry preparation and stable, pressurized delivery are fundamental to ensuring effective bentonite grouting. By integrating high-speed mixing, slurry storage, continuous agitation, and pressure injection capabilities, the Bentonite Slurry Mixing and Injection Plant streamlines construction workflows while enhancing slurry uniformity and grouting continuity.
Whether for tunnel reinforcement, foundation treatment, borehole grouting, dam seepage control, or mining projects, a properly configured bentonite mixing and injection plant enables contractors to minimize material waste, boost operational efficiency, and achieve consistent grouting quality.

Bentonite plants for diaphragm walls are widely used in projects such as subway stations, basements, deep excavation pits, underground passageways, and large-scale foundations. During the trench excavation process, the stability of the trench walls directly impacts both construction quality and safety. A stable and continuous supply of bentonite slurry is particularly crucial when working in loose soil layers, areas with high groundwater levels, or complex geological conditions.

The Bentonite Injection Plant for Tunnel and Foundation Projects is an integrated equipment system combining high-speed slurry mixing, low-speed storage, and pressure injection. It ensures a continuous and reliable supply of slurry for applications such as tunnel grouting, foundation reinforcement, borehole wall stabilization, underground seepage control, and deep foundation construction.
In tunneling, underground engineering, and foundation treatment projects, factors such as loose soil layers, rock mass fractures, and groundwater seepage can compromise construction safety and structural stability. To improve ground conditions, construction teams typically need to prepare a uniform, stable bentonite slurry and inject it—at design-specified pressures—into boreholes, fractures, or subsurface voids.

By integrating high-speed mixing, low-speed storage, and pressure injection into a single system, the bentonite injection grout plant significantly improves slurry uniformity and operational continuity. Whether for tunneling, borehole wall stabilization, ground improvement, diaphragm walls, pipe jacking, or seepage control projects, a properly configured bentonite grouting station ensures a stable supply of slurry.
For contractors, the ideal equipment is not necessarily the model with the highest capacity or pressure, but rather a system that precisely matches the slurry formula, geological conditions, project volume, and site environment.
