Wet Concrete Shotcrete Robot For Efficient Tunnel And Mine Construction Projects

Tailored to solve the pain points of high-intensity, complex construction environments, the robot is widely used in:

• Tunnel Construction:

  Suitable for highway tunnels, railway tunnels, and urban subway tunnels – effectively handles concrete spraying for tunnel walls, vaults, and confined curved surfaces.

• Mine Construction:

  Applicable to underground mine roadways, ore pass support, and goaf filling – adapts to narrow spaces and dusty, humid mine working conditions.

• Other Heavy-Duty Projects:

  Also used in slope protection engineering, large-scale culvert construction, and underground powerhouse spraying – meets the needs of high-altitude, large-area concrete application.

• Efficient Spraying to Speed Up Schedules:

  With high maximum conveying capacity, it can complete the concrete spraying of 50-80㎡ tunnel sections per hour – solves the problem of slow manual operation in tight-schedule tunnel/mine projects.

• Stable Pressure to Ensure Project Quality:

  Equipped with a powerful pump system, it maintains stable high-pressure delivery of concrete – avoids uneven spraying and hollowing in key parts like tunnel vaults, ensuring structural safety.

• Flexible Robotic Arm for Hard-to-Reach Areas:

  The big boom swings at a 120° angle, and the small boom supports 180° pitch + 1.5m telescopic range – easily reaches the top of 5m-high tunnels or narrow mine roadways (width ≥2.8m) without frequent equipment movement.

• Strong Environmental Resistance:

  The whole machine adopts dust-proof and waterproof design (IP54 rating) – works normally in mine dust or tunnel water seepage environments, reducing downtime.

• Remote Control to Avoid Hazards:

  Supports 50m wireless remote operation – operators can stand outside the tunnel/mine blasting area or toxic dust zone, eliminating the risk of injury from falling rocks or harmful gases.

• Intuitive Control for Precise Operation:

  The industrial control screen displays real-time parameters (conveying speed, adjuvant dosage, pressure) – even unskilled workers can master it in 1 hour, reducing training costs for construction teams.

• Heavy-Duty Chassis for Rough Sites:

  Adopts a reinforced diesel engine (meeting national emission standards) with water cooling system – works continuously for 8 hours in high-temperature (40℃) or low-temperature (-10℃) environments, suitable for long-term tunnel/mine construction.

• Stable Braking for Site Safety:

  Equipped with heavy-duty pneumatic brakes and anti-slip tires – maintains stable parking on sloped tunnel floors (≤15°) or uneven mine roads, preventing equipment sliding.

• High-Pressure Washer for Quick Cleaning:

  Built-in 30MPa high-pressure water system – cleans the spraying pipeline and nozzle in 10 minutes after work, avoiding concrete solidification and blocking (a common problem in manual cleaning).

• Adjustable Adjuvant System for Material Adaptability:

  Supports 0-5% adjuvant dosage adjustment – adapts to different concrete materials (e.g., fiber concrete for tunnel support, quick-setting concrete for mine emergency repair), improving construction flexibility.

Has been successfully applied in major projects:

• Dominican Republic Highway Tunnel Project:

  Completed 3km tunnel spraying in 2 months, 50% faster than manual operation.

• Indonesia Underground Mine Support Project:

  Maintained stable operation for 6 months in dusty environments, with zero equipment failures.

• Mexico Urban Subway Tunnel Project:

  Met the strict quality standards of subway construction, with the sprayed concrete layer passing 100% integrity testing.
