What is the brief introduction of the layer spraying process of wet shotcrete machine? I believe not everyone knows it. Let me introduce it to everyone.
① At the beginning of the spraying operation, the hopper and the conveying pipe are lubricated with clean slurry (50-100 kg of water-dilution slurry).
②, first supply air and water to the spray truck, check and adjust the wind pressure, the wind pressure is controlled at 9kg / cm2, and the water pressure is 4kg / cm2. Then turn on the main machine, and then feed again.
③ After entering the spray hopper of the wet shotcrete machine, adjust the spray speed of the spray truck while starting the main machine. The spray speed should be controlled at 10-15m3 / h. The amount of the accelerator is added according to the requirements of the mixing ratio of the rhenium, and the curve parameters of the injection speed and the accelerator are added to adjust the speed setting of the accelerator to control the amount of accelerator. When the material is delivered to the nozzle, the air valve is opened and the accelerator pump is started. The accelerator will penetrate the concrete at a high wind pressure at the nozzle to achieve the effect of rapid setting.
