grouting station for tunnel construction

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.

A complete grout station for micropile projects is an integrated, skid‑mounted or mobile system that combines high‑speed mixing, agitation, and high‑pressure grout pumping to produce and deliver cement/bentonite slurries for micropile installation, foundation reinforcement, and pressure grouting. It ensures continuous, controlled grouting for reliable pile‑soil bonding and load capacity.
