Today, Leadcrete Equipment shipped two grout injection stations to our customer in Australia.
 
This grout mixing and injection equipment is specialized construction machinery used primarily in geotechnical engineering, tunneling, foundation repair, and dam construction. It can handle various grout types (cement grout, chemical grout, asphalt grout, etc.) and adapt to different geological conditions (soft soil, rock, sand layers).
 
The efficient mixing and injection machine ensures uniform grout composition, preventing sedimentation or stratification and improving grouting quality. The injection pump uses pressure control to achieve grout penetration and diffusion in the target medium, meeting various engineering needs (such as waterproofing, reinforcement, and seepage prevention).
 
Key Components of Grout Mixing and Injection Equipment:
1. Mixing Unit
Hopper: Receives dry materials (e.g., cement, sand).
Agitator/Mixer: Blends dry components with water or other liquids to form a homogeneous slurry.
Water Metering System: Ensures precise water-to-cement ratios for consistent grout quality.
2. Grout Pump
Transfers the mixed grout from the mixing unit to the injection point.
Types include piston pumps, diaphragm pumps, and progressive cavity pumps, chosen based on viscosity and pressure requirements.
 
3. Injection System
Includes hoses, valves, and manifolds to direct grout to boreholes or cracks.
Often equipped with pressure gauges and flow meters for monitoring.
 
4. Control Panel
Centralized system for regulating mixing speed, pump rate, pressure, and volume.
Modern systems may feature PLC (Programmable Logic Controller), Automation and data logging.
5. Power Source
Diesel engine
 
6. Storage Tanks
Hold mixed grout temporarily or store liquid components before mixing.
 
Main Application Scenarios of Grout mixing and injection equipment:
Foundation Reinforcement: Injecting cement grout or chemical grout to improve the bearing capacity of soft soil foundations and reduce settlement.
Tunnel Construction: During tunnel excavation, grout is used to fill cracks in the surrounding rock and prevent groundwater seepage.
Geotechnical Engineering: Reinforcing slopes, dams, and other structures to enhance stability.
Concrete Repair: Injecting epoxy resin or other chemical grout to repair concrete cracks and extend structural lifespan.
Diaphragm Wall Construction: Injecting grout into the back of the wall to form a waterproof barrier and prevent groundwater seepage.
