水泥浇捣是建筑业灌浇水泥时,用电动振荡器剧烈振荡,把泥浆打匀。操作者称为浇捣工。经常接触强烈振荡,如果防护不好,会引起肢端血管痉挛、骨关节改变和末梢神经感觉障碍。这种病症临床上称为“震动病”。震动对机体的危害分全身性与局部性,因根源发出振幅和频率不同而产生的影响各异。振幅越大,频率愈低,愈容易成全身性危害。振幅小、频率高,易造成局部性危害。水泥浇捣工经常接触的是风动、电动工具, Concrete pouring is pouring cement construction industry, the use of electric shaker oscillation, the mud beat uniform. Operators called pouring Daoguang. Frequent contact with strong oscillation, if the protection is not good, can cause acral spasm, bone and joint changes and peripheral nerve sensory disturbances. Clinically, this condition is called “shock disease.” Shock on the body of the sub-body and local hazards, due to different sources of amplitude and frequency of the impact of different. Larger amplitude, the lower the frequency, the more likely to become a systemic hazard. Small amplitude, high frequency, easy to cause local hazards. Cement pouring workers often contact is the wind, power tools,
