Here's a practical guide:
✅ Recommended Wet Shotcrete Machine for 1000m Tunnel
1. Machine Type:
➡️ Robotic (mechanized) wet shotcrete machine
Equipped with manipulator arm (boom arm)
Ensures uniform spraying, better safety, and higher efficiency
Ideal for medium to large tunnels (4 m diameter or more)
2. Output Capacity:
➡️ 30–50 m³/h
40 m³/h is most commonly used for 1000m tunnel
Can finish work efficiently without over-sizing
3. Other Key Features:
| Feature | Recommended |
|---|---|
| Pump pressure | ≥ 8–10 MPa |
| Max aggregate size | ≤ 15 mm |
| Vertical spraying | ≥ 8–10 m |
| Horizontal reach | ≥ 10–12 m |
| Chassis | Diesel or electric, track or wheel-mounted |
Summary Recommendation:
For a 1000-meter tunnel, you should equip a robotic wet shotcrete machine with 40 m³/h output, boom arm, and high-pressure pump. This setup ensures efficient and safe concrete spraying, especially for tunnels around 5–7 meters in diameter.
Let me know your tunnel size or shotcrete thickness if you'd like a more specific model suggestion.
