目的检测和评价不同公路养护作业环境中的有害因素。方法选择不同交通流量、道路级别(国道、省道)和路面(沥青、水泥、砂石)的10个公路养护作业点,分别在春季(3月份)、夏季(7月份)和冬季(12月份)进行现场环境检测,内容包括气象条件、粉尘、毒物及物理因素等。结果不同公路养护作业环境中存在着不良的气象条件,粉尘浓度超标,空气中毒物含量较高,噪声强度大。结论公路养护作业环境中主要有害因素为粉尘、噪声和机动车尾废气。建议改善劳动条件,制定健康保护措施及完善劳动保障制度。
Objective To detect and evaluate the harmful factors in different road maintenance environment. Methods Ten road maintenance work points with different traffic flow, road level (national highway, provincial highway) and pavement (asphalt, cement and gravel) were selected in spring (March), summer (July) and winter ) Conducted on-site environmental testing, including meteorological conditions, dust, poison and physical factors. Results There were bad weather conditions in different road maintenance work environment, dust concentration exceeded, air poison content was high, and noise intensity was high. Conclusion The main harmful factors in the road maintenance environment are dust, noise and vehicle tail gas. Suggestions to improve working conditions, the development of health protection measures and improve the labor security system.
