摘要
在工程施工中,扬尘是对环境造成影响的一个因素,要想预防扬尘,需要对扬尘的质量浓度以及影响范围进行监测与分析。选择太原市2个具有代表性的工地,对工地不同区域扬尘的质量浓度进行了监测,获得了该工程施工阶段不同区域共计100次的扬尘质量浓度数据。以总飘尘质量浓度作为指标,参照工作场所有害物接触限值标准,得出了水泥加工区、道路两侧扬尘质量浓度和超标率较大的结果。水泥加工区扬尘呈现一定的规律,洒水措施对扬尘防治有一定的效果。
In engineering construction,flying dust is a factor that affects the environment.To prevent flying dust,it is necessary to monitor and analyze the mass concentration and influencing scope of flying dust.This paper selected two representative construction sites in Taiyuan City to monitor the flying dust mass concentration in different areas of the construction site,and obtained a total of 100 flying dust mass concentration data in different areas during the construction stage of the project.Taking the total mass concentration of flying dust as an indicator and referring to the hazardous substance exposure limit standards in the workplace,the results showed that the mass concentration and exceeding rate of flying dust in cement processing areas and on both sides of the road were relatively large.The flying dust in the cement processing areas shows a certain pattern,and water spraying measures have a certain effect on the prevention and control of flying dust.
