wet type rotor concrete shotcrete machine
When using the wet type rotor concrete shotcrete machine for the initial spraying, the rock surface should be sprayed with water and sprayed enough to the design thickness. This inch of stable surrounding rock is extremely important. When re-spraying, the steel arch or net should be sprayed flat, and the spray should be thick enough.

The operator should be familiar with the mechanical properties, especially the wind pressure, the distance of the sprayed surface, the spraying angle, the spraying sequence, and the thickness of each layer. It is also necessary to master the techniques of dry spraying, mixed spraying, tide spraying, and mixed spraying.
