wet concrete spraying gunite shotcrete machine
The wet concrete spraying gunite shotcrete machine occupies a large number of operators, due to the production of large amounts of dust, not only affect the environment, but also on the safety of production and the greater damage to the workers, but not conducive to underground construction operations.
The wet concrete spraying gunite shotcrete machine rebound rate of 15-50%, but also cause poor cohesion, especially in underground construction, will be subject to deformation of the crust and deformation, resulting in split and damage.
Wet-type shotcrete machine rebound rate of up to 10%, and because the slurry before the water and cement than the good mixing, so high cohesion, not easy to change with the crust and deformation, safety has an important role.
