国家规定建筑工程使用商品混凝土,因此各地新建和改建了不少混凝土搅拌企业,但其噪声和粉尘污染成为突出的问题之一。以上海浦东新区两个混凝土搅拌企业为例,采取设置大型半封闭隔声棚和隔声屏障技术措施,降低了噪声影响,达到了环保要求,可供同行参考。

According to the national regulation, commercial concrete must be used in all the building engineering, so premixed concrete enterprises are new-built or rebuilt everywhere in China. But the noise and dust pollution of these enterprises becomes a serious problem. In this paper, two enterprises in Shanghai-Pudong new area reduce the noise pollution and satisfy the environment criteria successfully by using the semi-closed sound-isolation house and the sound barrier. It can be an useful example in environmental engineering field.
