The use of shotcrete machine in our life is very wide, but here we still want to remind everyone that the maintenance work after the shotcrete machine is stopped, so that it will last longer, let me talk about the later maintenance work of the shotcrete machine.
The shotcrete machine will enter a "rest" state for a period of time. Although the work is about to end, it cannot be relaxed at this time, because the work with the shotcrete machine has not been completed. After the shotcrete machine is stopped, the remaining material in the conveying pipe is blown out first. When the pipeline is clean and no material is ejected from the nozzle, close the water valve at the nozzle. Then close the main air duct valve. And the shotcrete can remain in the hopper when the spraying operation is temporarily interrupted. If there is a long pause or the end of the spraying operation, stop the feeding first and let the machine continue to run until the residual material in the hopper and the rotor is finished. At the same time, add a little wet sand to the residual material in the hopper and the rotor cavity. Wash out spray. In this way, after the shotcrete machine is working, it is marked with a satisfactory mark.
