Frequently Asked Questions

Tunnel concrete spraying machine is a concrete spraying equipment specially designed for coating and strengthening of tunnel walls. These machines are ideal for spraying concrete mortar using high-pressure air and water.

Advantages of Tunnel Concrete Spraying Machine

Fast and Easy Application: It allows concrete to be sprayed quickly and easily, which shortens the construction time and reduces costs with the tunnel concrete spraying machine.

Homogeneous Coating: It forms a smooth and homogeneous coating, thereby increasing the durability of the tunnel.

Application to Complex Geometries: It can be easily applied to surfaces with complex geometry, providing access to every point of the tunnel.

Less Material Waste: It provides less material waste compared to traditional concrete casting methods.

The Working Principle of Tunnel Concrete Spraying Machines

The operation of the tunnel concrete spraying machine takes place in three steps: concrete preparation, spraying process and hardening. A homogeneous concrete mortar is formed by mixing water, cement and aggregates. The prepared mortar is transported to the spray gun using a high-pressure pump, and the spraying process is performed by adding water. The sprayed concrete mortar hardens to form a durable coating.

Areas of Use of Tunnel Concrete Spraying Machines

The tunnel concrete spraying machine is used in many fields, such as coating and strengthening of tunnel walls, as well as mine galleries, pools, dams, foundations of buildings and stabilization of rocky slopes. Technical Characteristics of Tunnel Concrete Spraying Machine Pump Capacity: The pump capacity of the tunnel concrete spraying machine determines the amount of concrete it can spray per unit time. High capacity pumps are suitable for large projects. Working Pressure: Concrete spraying machines operate at a certain pressure. High pressure allows the concrete to adhere better to the surface.

Technical Characteristics of Tunnel Concrete Spraying Machine

Pump Capacity: The pump capacity of the tunnel concrete spraying machine determines the amount of concrete it can spray per unit time. High capacity pumps are suitable for large projects.

Working Pressure: Concrete spraying machines operate at a certain pressure. High pressure allows the concrete to adhere better to the surface.

Hose Length and Flexibility: The hose of the machine determines the distance to which the concrete will be delivered. Flexible and long hoses provide a more effective application in large areas.

Maintenance and Repair of Tunnel Concrete Spraying Machines

Regular Maintenance Procedures: Regular maintenance of the tunnel concrete spraying machine is a must for a long service life and trouble-free operation. Cleaning and lubrication operations should be carried out regularly.

Common Malfunctions and Solutions: Common malfunctions in concrete spraying machines include hose blockages and pump Deceptions. These problems can usually be prevented with routine maintenance and proper use.

Frequently Asked Questions
