摘要
在倒塌场地狭小的条件下,采用定向爆破方法成功拆除了一座150 m高钢筋砼结构烟囱。介绍了爆破切口形状、切口参数和爆破参数的选择以及安全验算,通过开挖减振沟、铺垫缓冲层等安全防护措施,降低了触地振动和爆破飞石危害,确保了附近厂房的安全,可供类似工程参考。
A practical example of directional blasting demolition of a RC smoke stack with a height of 150 meter in a narrow surrounding was presented. The paper discussed the form and parameters of blasting cuts and the selection of the blasting parameters and security checked, through digging the vibration ditch, foreshadowing the buffer layer of security protection measures ,reducing the damage of the touchdown blasting vibration and flying rocks hazards, ensure the safety of nearby plants,it can be used as certain reference for similar projects.
