Based on some problems existed in shotcrete machine at present, technological research and innovation was made to research and use full air pressure pneumatic concrete sprayer with pneumatic pump driven by pressure wind as power source, which had advantages of dynamic stability, environmental protection, energy saving, no concerning any electrical, safe and reliable, as well as easy maintenance and operation. Just opened the valve and it could work, which reached the purpose of safety, high efficiency, dust reduction, energy saving and low consumption.
