Excavation support hoisting type spraying machine Jingheng coal mine spraying unit material

Description :

　　Excavation support hoisting type spraying machine Jingheng coal mine spraying unit material

　　The lifting and spraying machine improves work efficiency, without stopping the machine, and can work continuously. The hopper automatically loads materials, saving manual labor. The size of the machine can be selected according to the construction environment to facilitate construction and increase workload. In terms of machine operation, it is also very user-friendly. The machine can start working as soon as it arrives, and everyone can operate it.

　　Dry spray process

　　① Process flow

　　Various materials (excluding water) are dry mixed according to the design ratio requirements - the mixed loose concrete is directly fed in (through)

　　Through mechanical or manual feeding, the material is carried by the compressed air provided by the air compressor and transported to the nozzle through the feeding pipe

　　Add water and material mixture here and spray it onto the sprayed surface under wind pressure.

　　2. Wet spraying process

　　① Process flow

　　Various materials (including water) are thoroughly mixed according to the design ratio requirements - the mixed concrete is directly fed in (through)

　　The strong vibration hopper of the mechanical or manual feeding wet spraying machine - the compressed air provided by the air compressor carries the material through the conveying pipe

　　Transported to the nozzle - where the rapid setting agent is added and mixed with the material - sprayed onto the sprayed surface under the action of wind. The material of the Jingheng coal mine spraying unit of the foundation pit support hoisting type spraying machine is used.

　　Scope of application

　　The spraying machine is applied in the construction of sprayed concrete in mines, tunnels, culverts, subways, hydropower engineering, underground engineering, and coal mine tunnels in high swamp mines.

　　1) Underground engineering: The main support and lining for mining tunnels, flexible tunnels, hydraulic tunnels, and various types of cavities used (underground power stations, underground warehouses, movies, etc.).

　　2) Thin walled structural engineering: thin shell roofs, prestressed construction for building reservoirs and storage tanks, etc.

　　3) Repair and reinforcement engineering: Bridge, seawall, chimney, cooling, bridge, dam, tunnel, dock, building structure reinforcement, chemical corrosion, fire, earthquake, explosion impact, overload or construction quality, the most unfavorable factors, such as repairing damaged structures.

　　4) Breakwaters in geotechnical engineering, slopes, dams, tunnels, reservoirs, swimming pools, deep excavations, irrigation, and retaining walls.

　　5) Protective engineering: various types of fire-resistant coatings for steel structures.

　　6) Refractory material project: Materials for chimneys and various hot melting furnaces in buildings, as well as for repairing foundation pits, support, hoisting, and spraying machines for Jingheng coal mine spraying units.
