多向倒塌技术爆破拆除复杂结构楼房

爆破拆除宽为13 m、东西长111 m、高为12 m的复杂砖混结构楼房,在楼房高宽比值不大,整体性较差的情况下,对需要保护周围树木、建筑物等的复杂环境,选择多向倒塌联合爆破拆除方案.合理选择爆破时差、顺序和爆破参数,保证了各部分按设计各自定向或内向倒塌;并采取有效措施,减少爆破个别飞散物、降低爆破震动和爆破粉尘等爆破危害.

Application of Multi-direction Collapse in Explosive Demolition of Complex Special-shaped Structure

A special-shaped building with 13 m width,111 m length and 12m height was demolished.On the less of aspect ratio and poor integrity condition,the multi-direction collapse scheme was the first choice to demolish on such complex surrounding with trees protected and other buildings.The reasonable delay interval and order and other parameters were the key to guarantee each collapse direction.Taking effect measures can reduce the flyrock,blasting vibration and dust.
