Dry Shotcrete Machine

The dry shotcrete machine is a device that uses compressed air to spray pre-mixed dry concrete materials (cement, sand, aggregate, etc.) at high speed onto the sprayed surface, and then mixes them with water to solidify into concrete. It is widely used in tunnels, mines, water conservancy projects, and other fields for lining, reinforcement, repair, and other projects.【WhatsApp/WeChat/Phone/Skype】+86 136 1385 6800

Application Fields of Dry Shotcrete Machines Worldwide:

  1. Tunnel engineering: Dry shotcrete machines are widely used in tunnel lining, reinforcement, waterproofing, and other projects. Especially in large-scale projects such as high-speed railways, subways, and highway tunnels, dry shotcrete machines play a key role.
  2. Mining engineering: Dry shotcrete machines have the advantages of high efficiency and reliability in mine tunnel support and anchoring.
  3. Water conservancy projects: Dry shotcrete machines are used in dam reinforcement, anti-seepage, and other projects, which can quickly repair damaged parts and improve the stability of the project.
  4. Underground projects: Dry shotcrete machines are widely used in urban underground spaces, underground garages, and other projects for lining, waterproofing, etc.
  5. Industrial facilities: Dry shotcrete machines are used to maintain and reinforce industrial facilities such as chimneys and cooling towers.

Application Case Analysis in Various Countries:

  1. China: China is one of the world’s largest infrastructure construction markets, and dry shotcrete machines have been widely used in high-speed rail, subway, tunnel, and other projects. For example, in my country’s South-to-North Water Diversion Project, dry shotcrete machines are used to line tunnels, ensuring the quality and progress of the project.
  2. Europe: European countries also attach great importance to infrastructure construction and dry shotcrete machines are widely used in tunnels, subways, and other projects. For example, in the Alps Tunnel Project, dry shotcrete machines are used to line tunnels to ensure the stability of tunnels.
  3. North America: The demand for dry shotcrete machines is mainly concentrated in mining and tunnel engineering. For example, some mines in Canada use dry shotcrete machines for tunnel support, which improves the safety of mines.
  4. Other parts of Asia: Asian countries such as Japan and South Korea also widely use dry shotcrete machines, especially in tunnel engineering and underground space construction.

 

Principles and Characteristics of Dry Shotcrete Machine:

Working principle:

Dry concrete materials (cement, sand, aggregate, etc.) are transported to the nozzle by compressed air, mixed with high-pressure water at the nozzle to form concrete, and sprayed onto the sprayed surface at high speed. The sprayed concrete particles are tightly combined with the sprayed surface to form a solid concrete layer.

Main features:

  1. Efficient construction: The dry shotcrete machine has a fast construction speed and can greatly improve construction efficiency.
  2. Strong adaptability: It can be used for the construction of surfaces of various shapes and complexities.
  3. High material utilization rate: The rebound rate of dry shotcrete materials is low and the material utilization rate is high.
  4. Good construction quality: The shotcrete has high density, high strength, and good durability.
  5. Easy operation: Modern dry shotcrete machines have a high degree of automation and are easy to operate.
