🔧 What It Is
A stationary concrete pump is a fixed-position pumping unit that delivers concrete through pipelines or hoses to the exact placement point.
Installed outside or at the tunnel portal
Concrete is fed into the hopper
Pump pushes material through steel pipes into the tunnel
🚇 Why It's Ideal for Tunnel Support
1. Long-Distance Pumping
Can pump hundreds of meters horizontally into tunnels
Suitable for deep or long tunnel sections
2. Works in Confined Spaces
No boom needed → only pipelines inside tunnel
Keeps working area clear for drilling, bolting, and spraying
3. Continuous Concrete Supply
Provides stable, uninterrupted flow for:
Tunnel lining
Invert concrete
Secondary lining
Shotcrete feeding
4. High Pressure Performance
Designed for high-pressure pumping to overcome pipeline resistance
⚙️ Typical Technical Range (for tunnel use)
Output capacity: 30–90 m³/h
Pumping pressure: up to 10–16 MPa
Horizontal distance: up to 500–1000 m
Vertical distance: up to 120–260 m
🔄 Typical Tunnel Workflow
Concrete mixingFrom batching plant or mixer truck
FeedingConcrete discharged into pump hopper
PumpingPump pushes concrete through pipelines into tunnel
ApplicationConnected to:
Wet shotcrete machine
Formwork for lining
Manual placement zones
🏗️ Common Tunnel Applications
Primary support (shotcrete supply)
Secondary lining concrete
Invert slab concreting
Portal and entrance structures
Grouting and backfilling
Stationary pumps are widely used because they can stay outside the tunnel while delivering concrete deep inside safely and efficiently.
⚡ Diesel vs Electric (Tunnel Selection)
Diesel pump
Best for remote tunnels
No need for external power
Electric pump
Preferred in urban tunnels
Lower noise & zero emissions
✅ Key Advantages for Tunnel Projects
Compact and easy to install
Reliable for continuous operation
Reduces labor and equipment movement
Compatible with long pipeline layouts
High efficiency in confined environments
If you want, we can help you:
Choose the right model (e.g., 40 / 60 / 80 m³/h) for your tunnel size
Match it with shotcrete machines or mixer trucks
