复杂结构立筒库控制爆破拆除

Controlled Blasting Demolition of Vertical Sleeve Storage with Complicated Framework

介绍了某面粉厂内由2排共6个联体砖混结构筒仓组成的立筒库的爆破拆除。对立筒库采用分段延期定向爆破拆除方案,并取得了理想效果。着重论述了立筒库爆破切口高度计算、药孔参数设计、安全防护措施,为同类建筑物爆破拆除提供参考和依据。

The blasting demoliton of a vertical sleeve storage which is made up of six combined brick-concrete tubular storehouses arranged in tow lines is introduced.The directional blating demolition scheme adopting subsection hangfire of vertical sleeve storage is adopted and the prospective blasting effectiveness is achieved.The calculation of blasting cut′s height,parameters design of powder chamber,safety protection measures are discussed mainly.The example can be refered for the blasting demoliton of the similar buildings.
