Here's what you need to know:
Key Features of a 25m Wet Shotcrete Machine with Special Air Compressor
Long Reach (25m Arm or Boom)
Suitable for large tunnels and caverns where high coverage is required.
Reduces the need for repositioning, increasing efficiency.
Wet Shotcrete System
Uses pre-mixed concrete with accelerators to provide fast setting and high strength.
Ensures uniform application with less dust and rebound compared to dry shotcrete.
Special Air Compressor
High-capacity airflow and pressure to support smooth concrete spraying.
Ensures proper atomization and adhesion of shotcrete.
Helps maintain continuous operation in long-distance spraying.
Robotic Arm or Telescopic Boom
Automated control for precise application and operator safety.
Hydraulic or electric-powered movement for flexibility in different tunnel sections.
High Efficiency & Productivity
Reduces manual labor and speeds up the tunnel support process.
Ideal for NATM (New Austrian Tunneling Method) and TBM-excavated tunnels.
When to Use It?
Immediately after excavation for initial tunnel support.
During primary lining installation to stabilize the structure.
In large-diameter tunnels where high-reaching shotcrete application is required.
