grout unit for tunnel grouting

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:

Grout unit for tunnel grouting work is suitable for all grouting applications with cement and ultra-fine cement, bentonite suspensions for micro-tunneling, pipe jacking and directional drilling. Grout plants are ergonomic, space saving. Mixing and agitating station can be also detached from the unit for individual use.
