The wind-proof and dust-suppressing net is based on the principle of aerodynamics, and is processed into a wind-proof and dust-suppressing wall with a certain geometric shape, opening ratio and different hole shapes according to the results of the wind tunnel experiment in the field environment, so that the circulating air (strong wind) passes through the wall from the outside. When combined, the upper and lower interference airflows are formed on the inner side of the wall to achieve the effect of strong wind on the outside, weak wind on the inside, small wind on the outside, and no wind on the inside, so as to prevent the flying of dust.
