Wet shotcrete machine is mainly used in mine roadway, railway road tunnel, underground building, high-rise building foundation pit and road slope and coal-fired high-altitude mine roadway shotcrete construction operation.
The working principle of wet shotcrete machine: The mixed dry material is manually and evenly loaded into the hopper of the mixer, and the ball valve of the gas valve and the water adding device is opened, and the material is humidified by the mixer and stirred uniformly, and then sent to the jetting machine. Then, the pressurized gas is sent to the surface to be sprayed through the feed pipe and the nozzle. When the mixture enters the nozzle and is to be ejected, it is mixed with the liquid quick-setting agent outputted by the accelerator pump to achieve the purpose of accelerated solidification of the concrete.
