grout plant for tunnel grouting

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.

The bentonite grouting and mixing system for tunneling is an integrated slurry preparation and grouting unit custom-engineered for tunnel excavation projects. It is designed to handle key tunneling applications such as synchronous grouting for shield machines, annular gap backfilling, and borehole wall stabilization in complex geological conditions. The system supports operations including synchronous backfill grouting, slurry-supported micro-tunneling, diaphragm wall stabilization, and borehole wall support in complex sand-and-cobble strata, while also meeting requirements for drill cutting suspension and transport, as well as the lubrication and cooling of drilling tools.

Grout stations for tunnel grouting work are widely used in various tunnel and underground engineering projects, including but not limited to:
Tunnel foundations and linings.
Contact grouting and shaft waterproofing in mining projects.
Ground anchor installations and soil nail walls in civil engineering projects.
Foundation stabilization and soil compaction grouting in structural restoration projects.

Grout equipment is designed specifically for tunnel grouting operations. These equipment are essential to ensure structural integrity and waterproofing during tunnel construction. Some common types of tunnel grouting equipment are detailed below:
