Research on the Application of Composite Dust Suppressant on Road Construction Site
Aiming at the dust generated at the road construction site,the composite dust suppressant developed was tested on site to determine the dilution times and spraying amount and to verify the dust suppression effect.The application results are as follows:Through the drying time,surface crusting and solution exudation,the optimal spraying amount of the dust suppressant solution under high temperature in summer is determined to be 1.5 L/m2,and it is necessary to make up the spraying once every 2 h;the monitoring data of air particulate concentration before and after the actual application on the site are analyzed,which proves that the composite dust suppressant can effectively reduce the concentration of PM2.5,PM 10 and TSP(total suspended particles)in the environment;test the wind erosion resistance of the soil after spra-ying the dust suppressant,analyze the action mechanism of the composite dust suppressant,estimate the application cost of the dust suppressant by combining with the site conditions,it is proved that the composite dust suppressant has both excellent wind erosion resistance and economic and environmental protection characteristics when it is diluted at a multiple of 40.
