Most of the spray effects of the excavation working faces are not good, and dust cannot be reduced on the entire section. To a certain extent, it not only harms the health of workers, but also the overall appearance of the tunnel is not optimal. For this reason, the principle of Feng Shui is used to pressurize the water with wind pressure to form an atomization effect.
