1. Concrete Spraying
The machine delivers premixed wet concrete through a conveying pipeline to the spray nozzle. Compressed air then accelerates the concrete onto the target surface, forming a dense shotcrete layer.
Main advantages:
Continuous wet concrete spraying
High spraying efficiency
More uniform concrete coverage
Reduced material handling
Suitable for large-area applications
2. Slope Protection
For high and steep slopes, wet shotcrete can form a protective concrete layer over exposed rock or soil surfaces. This helps stabilize the surface and reduce the effects of weathering and erosion.
Typical applications include:
High-slope protection
Rock slope stabilization
Highway slope protection
Hydropower project slopes
Excavation slope reinforcement
3. Tunnel Support
In tunnel construction, shotcrete is commonly used as part of the initial support system after excavation. The sprayed concrete covers exposed rock surfaces and helps stabilize the excavation.
The machine can be used for:
Tunnel excavation support
Rock surface reinforcement
Tunnel wall spraying
Underground mine support
Hydropower tunnel construction
4. Efficient and Continuous Operation
A wet shotcrete machine can continuously transport and spray concrete, making it suitable for projects requiring large quantities of shotcrete. A robotic boom or spraying arm can also improve the operator's working range and reduce the need for manual handling.
5. Better Working Conditions
Remote-controlled or robotic wet shotcrete equipment allows the operator to work farther away from the spraying area. This can reduce direct exposure to dust, rebound, falling rocks, and other hazards, depending on the site conditions and safety procedures.
6. Suitable for Different Construction Projects
The equipment can be configured for different applications, including:
Tunnels → Slope protection → Mines → Hydropower projects → Underground construction → Rock reinforcement
