Concrete wet spraying machine is a kind of construction equipment widely used in engineering construction. It uses compressed air or other power to transport the mixed material in a certain proportion through the pipeline and spray it at a high speed to the sprayed surface to condense and harden, thereby forming a concrete support. The protective layer, shotcrete technology is simple, the construction cost is low, the adaptability is wide, the operation dust is small, the spray rebound is less, the protection of the working environment, the saving of raw materials, and the improvement of the spray layer quality have played an important role in various construction fields.
Uses of concrete wet spraying machine:
1. The dust concentration beside the machine and outside the nozzle is greatly reduced, and the hazard to workers' health is eliminated.
2. The working efficiency of the pump type wet spraying machine can reach 10m3/h, which greatly improves the construction efficiency.
3. Low resilience. Using a pump-type wet sprayer for wet spraying, the rebound rate can be reduced to less than 10%.
4. During wet spraying, because the water-cement ratio is easy to control and the degree of concrete hydration is high, it can greatly improve the quality of shotcrete and improve the homogeneity of concrete.
