Introduction to shotcrete machine
Shotcrete machine is a new type of high-efficiency shotcrete machine, which is mainly suitable for concrete shotcrete operations in *-section tunnels. This equipment uses a concrete pump to transport concrete to the robot nozzle through a pipeline, and uses compressed air with accelerator to spray the concrete onto the wall of the tunnel to be sprayed. It has a reasonable structure, humanized design, reliable performance, convenient operation and maintenance, and a long service life. Dust-free, low noise and low rebound rate during operation.

This machine greatly reduces the dust concentration next to the machine and at the nozzle, improves the working environment of workers, and reduces pneumoconiosis caused by excessive dust. This equipment has obtained three national patents.

Applications of shotcrete machines
Construction shotcrete machines are widely used in engineering construction, mines, tunnels, culverts, subways, hydropower projects, underground projects and coal Spray concrete construction operations in high-marsh mine tunnels: various types of industrial furnaces, refractory lining spray molding or repair: soil transportation and spraying in various slope protection and greening constructions.
Advantages of shotcrete machine
Straight-through rotor type non-bonded material cavity, smooth material discharge, efficient and time-saving: four-point elastic compensation compression, good sealing effect, less dust around the machine, long life of wearing parts Long: Adopt low-pressure and high-speed vortex airflow transportation to overcome problems such as sticking, pipe blocking, and pulse separation during material transportation. The material flow is uniform, continuous and stable: new nozzles and discharge elbow devices improve the spraying effect and reduce rebound. , spray layer quality is high. The machine chassis can be assembled into tire skid type and rail wheel type with various gauges.
