bentonite grout plant

Gaode Equipment offers a high pressure grout plant combining twin mixing tanks and a plunger pump for cement grout preparation and injection. Suitable configurations support foundation grouting, rock anchoring, and soil nailing. Mixing capacity, pumping pressure, flow rate, and power options can be tailored to your project requirements.

The double-plunger bentonite grout pump is a positive-displacement grouting unit specifically designed for high-viscosity bentonite slurries. It achieves continuous suction and discharge through the alternating reciprocating motion of two plungers, significantly reducing pressure pulsation compared to single-plunger pumps, and serves as core grouting equipment for tunneling, mining, and foundation reinforcement projects.
Applications of the double-plunger bentonite grout pump:
Synchronous and secondary backfill grouting for shield tunnels, enabling precise control of surface settlement
Grouting for diaphragm walls and dam curtains to stabilize geological structures and prevent water seepage
Reinforcement and water-blocking in fractured rock strata within underground mines; suitable for explosion-proof operating environments
Long-distance transport of bentonite friction-reducing slurry for trenchless pipe-jacking projects
Grouting for micropiles and anchor rods; foundation reinforcement in confined spaces

A cement bentonite grout mixing plant is a specialized system designed to produce homogeneous, stable slurries used primarily in geotechnical and civil engineering applications such as: Slurry walls (diaphragm walls), groundwater cutoff, tunneling and shaft sealing, landfill containment barriers, and soil nailing and ground improvement. Working Principle: Premixing Stage: Bentonite and water are thoroughly dispersed under low-speed stirring to form a colloidal solution.
Main Mixing Stage: Cement and additives are added, and homogeneous mixing is achieved through high-speed shear mixing.
Transportation and Storage: The mixed slurry is transported to the construction site via a pumping system or temporarily stored in mixing tanks to maintain its fluidity.
