Research on the Application of Green Construction Technology in Construction Projects
In view of the serious dust and large environmental pollution at the construction site of a project,through green construction technolo-gy,composite dust suppressant was used to control construction dust,and the effect of different dust suppression measures was compared,the research results showed that the optimal spraying amount of composite dust suppressant was 1.5 L/m2,and it was recommended to carry out supplementary spraying every 2 hours to maintain a continuous and effective dust suppression effect.The PM 2.5 concentration in the site showed a gradual decreasing trend after spraying dust suppressants,and the obvious decrease was in the areas where 6#,5#,and 4#dust sup-pressants were used,with a decrease of 20 m/m2.The wind erosion rate of the dust sample after treatment with 5#dust suppressant was only 0.431%,and the wind erosion resistance was the strongest.Through the comprehensive evaluation of the economic benefits of a single dust sup-pressant,sprinkling,laying a dust net and a composite dust suppressant,it can be concluded that the composite dust suppressant has the best economic benefits,and because the wind erosion resistance and dust suppression effect of 5#dust suppressant are the best,it is suitable for popularization.
