The invention relates to the technical field of a material yard windshield and dust suppression wall of raw materials stacked in open air of a factory, in particular to a material yard windshield anddust suppression wall consisting of a foundation cushion, a windshield wall body, a windshield plate steel structure support, a windshield plate and a spray device. The concrete construction method comprises five steps of foundation cushion construction, windshield wall body construction, windshield steel structure support installation, windshield plate installation and spray device installation.The windshield and dust suppression wall can effectively reduce wind speed, attenuate turbulence, contain dust and control dust pollution, the wind pressure is 55 kg/m<2>, the seismic fortification intensity is 8 degrees, the foundation and steel structure design service life is 50 years, and the windshield plate service life is 20 years. The bottom area of the cushion is large, the bearing capacity is high, and the resistance to terrain deformation is high; the windshield wall body has high bearing capacity; the windshield plate is fixed by a rigid structure support, is anti-static, flame-retardant and anti-ultraviolet, the turbulence degree of wind is reduced, and the eddy current of the incoming wind is eliminated; the shear stress and pressure on the surfaces of the raw materials are reduced, so that the dust rate of a material pile is reduced; and spray atomization water can effectively control dust.
