How to use hydraulic wet mix shotcrete machine chapter 1
1. Before starting the hydraulic wet mix shotcrete machine, the high pressure air should be turned on, idle for a few minutes, blow out the residual liquid and dirt in the wet mix shotcrete machine pipeline, and check whether the pipeline is smooth; when the main air valve is closed, the system The wet mix shotcrete machine can be turned on only when the wind pressure is displayed above 0.5MPa.
2. Blow out all the surfaces to be sprayed with compressed air or pressurized water to remove loose impurities or dust on the surfaces to be sprayed; ensure that the wet spraying speed of the wet sprayer is appropriate to facilitate the compaction of concrete.
3. Keep an appropriate distance between the nozzle of the wet mix shotcrete machine and the sprayed surface, and the wet spraying angle should be as close to 90 degrees as possible, so as to obtain a large compaction force and small rebound; Honeycombs or gizzards appear on the back of the steel bar.
4. When starting or stopping wet spraying, give a signal to the wet mix shotcrete machine driver. When the material flow cannot be sprayed evenly from the nozzle, the wet mix shotcrete machine driver should also be notified to stop the operation.
Well, this article is over here, and the next article will continue to share the use of hydraulic wet mix shotcrete machine for you.
