摘要
为了解建筑施工噪声和扬尘排放及其对建筑工人的暴露现状,以更加有针对性的制定相应管控措施,本文选取了上海地区的一栋在施的装配式混凝土结构住宅和现浇剪力墙结构住宅进行实测对比,在夏季(5月份)微风条件下,楼层的同一高度(约20m),对噪声、扬尘数据进行监测,得出不同施工工艺的噪声、扬尘的暴露值和环境排放值,研究发现,混凝浇筑和铝木模板安装工艺,最大声压级均超过90d B,而拆模清理和混凝土浇筑过程的扬尘排放较高,颗粒物浓度约为200ug/m^3。通过统计分析、对比发现,装配式建筑的噪声排放比现浇剪力墙结构低约3%,扬尘排放低约20%,体现了装配式建筑在绿色施工方面的巨大优势。最后,对施工现场噪声和扬尘的控制方法进行了总结分析。
To understand the status of building construction noise and dust emission and the exposure to construction workers,and to more targeted to develop appropriate control measures,in this paper,a comparison was made between a housing building with the assembly of the concrete structure and the cast-in-place shear wall structure in Shanghai. In the summer(May) breeze condition,the same height of the floor(about 20 meters),through monitoring noise and dust data,the exposure value of noise and dust of different construction techniques and the environmental emission values were obtained.The study found that in coagulation casting and aluminum wood template installation process,the maximum sound pressure level are more than 90 d B,while dust emissions in cleaning and stripping of concrete pouring process are higher,particle concentration is about 200 ug/m^3. Through statistical analysis and comparison,the noise emission of the assembly building is about 3% lower than that of the cast-in-place shear wall structure,and at the same time dust emissions about 20% lower,which embodies the great advantages of the assembly building in the green construction. Finally,the control methods of noise and dust in construction site are summarized and analyzed.
