摘要
在对砖砌建筑物进行爆破拆除时,由于所采用原材料的特性、建筑物结构特点等因素,致使产生爆破粉尘的浓度很大,粉尘在空中滞留的时间较长,并且粉尘扩散的范围很广,对环境保护造成极大影响。根据对砖砌建筑物爆破时产生粉尘的根源进行详细分析,提出合理的除尘技术措施。实践证明,采用了这些综合措施后降尘效果显著,与不采取降尘措施的砖砌建筑物拆除爆破工程相比,爆后粉尘减少90%以上。
In the blasting demolition of brick structures, due to the characteristics of the adopted raw materials and the construction characteristics etc, the density of dust is very big, time that detained dust in the sky is longer, and the scope that dust proliferation is wide, all these impair the environmental protection. Through analyzing the brick building dust-reduction techniques, reasonable measures are put forward. The practice shows that markedly effective dust-reduction is obtained after these comprehensive measures are taken. Compared to the demolition blasting engineering without dust-reduction measure of the building with bricks, the dust is reduced by at least 90%.
