Material yard windshield and dust suppression wall and construction method

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of a stockyard wind-proof and dust-suppressing wall where factory raw materials are stacked in the open air, in particular to a stock-yard wind-proof and dust-suppressing wall and a construction method thereof. Background technique [0002] Due to the large reserves of raw materials stacked in the open air in the stockyard and the frequent wind season, dust particles mainly have three movement states under the action of wind: the largest moving particles (diameter > 1000 microns) roll along the ground and become spiral motion under a certain wind speed, and the tiny Particles (diameter < 100 microns) are carried by turbulence and move with the wind called suspension; particles in the middle (100 microns-1000 microns) first jump into the atmosphere, and then fall back to the ground along a regular track, which is called jumping . Suspension and jumping of particles are the main movement forms of wind e...

AI Technical Summary

Problems solved by technology

Suspension and jumping of particles are the main movement forms of wind erosion phenomenon; as long as the suspended particles, especially the particles below 10 microns are suspended in the atmosphere, are the most harmful to the atmospheric environment, once these particles are suspended in the air , due to the speed fluctuation in the vertical direction, it is difficult to fall back to the ground, but it spreads to other places with the wind, which leads to serious air pollution and other environmental problems, and also causes waste of raw materials and increases the cost
