Shotcrete machine for wet and dry application
Shotcrete machine for wet and dry application, that is, wet and dry dual-purpose shotcrete machine, is a commonly used equipment in construction projects. Wet and dry mix shotcrete machine is a kind of mechanical equipment that can spray concrete materials onto the construction surface at high speed through compressed air or mechanical power. It is suitable for both wet spraying and dry spraying processes and can be flexibly adjusted according to construction needs.
Working principle of shotcrete machine for wet and dry application:
Wet spraying process:
Add the mixed wet concrete to the sprayer.
Under the action of compressed air or mechanical power, the concrete is transported to the nozzle through the conveying pipe.
The nozzle sprays the concrete onto the construction surface at high speed to form a dense concrete layer.
Dry spraying process:
Dry materials such as cement, coarse and fine aggregates and accelerators are mixed evenly by manual or mechanical dry method.
The dry mixture is transported to the nozzle with compressed air, and pressurized water is added in front of the nozzle according to the specified water-cement ratio.
After the dry mixture is quickly mixed with water into concrete, it is sprayed onto the construction surface by the nozzle.
Application field of wet and dry mix shotcrete machines:
Wet and dry spraying concrete machines are widely used in various construction projects, such as tunnels, mines, subways, water conservancy, and construction. Especially in occasions where rapid support and reinforcement are required, such as tunnel linings, bridge bottom plates, and other narrow spaces or irregular construction surfaces, wet and dry spraying concrete machines play an important role.
Advantages and precautions:
Advantages:
High construction efficiency: The spraying of concrete can be completed quickly.
Wide range of applications: suitable for a variety of construction environments and process requirements.
Good spraying quality: can form a dense concrete layer and improve the support effect.
Precautions:
Before use, check whether all parts of the equipment are intact to ensure that the equipment can operate normally.
During the spraying process, attention should be paid to controlling the spraying speed and spraying volume to avoid waste and safety hazards.
After the construction is completed, the equipment should be cleaned in time to avoid damage to the equipment caused by concrete residue.
In summary, the wet and dry shotcrete machine is an indispensable and important equipment in construction projects. It can improve construction efficiency and quality, reduce labor intensity and safety risks. When using, attention should be paid to operating specifications and maintenance to ensure the normal operation of the equipment and extend its service life.
