The wet shotcrete machine sprays the concrete by mixing the aggregate, cement and water uniformly according to the design proportion. The wet concrete shotcrete machine is used to press the mixed concrete mixture to the nozzle, and then the accelerator is filled with an accelerator. The quality of wet shotcrete is easier to control.
When spraying the wet shotcrete machine, the water-cement ratio and the amount of accelerator should be strictly controlled. After spraying, the surface of the sprayed layer should be smooth and smooth, without dry spots or slippage. When spraying the concrete with wet shotcrete machine, press the spiral S-shaped movement forward, S-shaped reciprocating movement can also be used.
When spraying the concrete wet shotcrete machine, the air must be turned on before the machine is turned on. When stopping, the stopper must be turned off before the gas is turned off to prevent the cement slurry from entering the gas path. After the spraying is finished, the gas path must be opened to flush the gas path later, and then the spray head must be removed and stowed. In order to ensure the liquid absorption capacity of the accelerator pump, the gas channel of the accelerator pump should be opened first, and then to the main gas path of the nozzle. After the spraying is finished, the accelerator pump should be flushed with water for more than one minute, and the pipeline should be cleaned to prevent the remaining accelerator setting sediment from blocking the pump.
