dry concrete gunite shotcrete spraying machine
The dry concrete gunite shotcrete spraying machine always observe the level indicator of the accelerator tank and add the accelerator; When feeding material to the hopper, remember to explode the continuous and uniform flow, and make sure that the material can not completely block the material opening.
The dry concrete gunite shotcrete spraying machine working process is dry-mixed material is conveyed by compressed air and has a high speed at the outlet of the spray gun, which can fill the fissures and joints of the surrounding rock well, and can fill the rock surface of the cavity.
The concrete filled in the rock cracks or cracks not only has a high cohesive force, but also increases the friction between the rock cracks, acting as a “wedge”, so that the originally separated rock masses can be tightly united As a whole, it effectively prevents the relative movement between the rock masses and enhances the supporting ability of the surrounding rock itself.
