我厂混凝土构件成型过程中的振动噪声,通常达110分贝(A)以上,由于十多个振动设备都在同一座厂房内,操作时,整个车间震耳欲聋,不仅在振动成型台上直接操作的工人深受其害,就是其它工序的工人也难以忍受。长期来,噪声严重地影响着工人的身体健康,不少同志已出现头疼、耳鸣、失眠、高血压与心跳过速等病症。过去,我们也曾采取过一些措施,但是效果都不明显。如何克服振动噪声,已成为我厂生产工艺中的一个急待解决的“老大难”问题。
The vibration noise of the concrete components during the molding process of our factory is usually 110 decibels (A) or more. Since more than ten vibration equipments are in the same factory building, the entire workshop is deafening and not only the workers directly operating on the vibration forming table. It is deeply harmed that workers in other processes are unbearable. In the long term, noise has seriously affected the health of workers. Many comrades have experienced headaches, tinnitus, insomnia, hypertension and tachycardia. In the past, we have taken some measures, but the effect is not obvious. How to overcome vibration and noise has become an urgent issue in our factory’s production process.
