Symmetrically folded collapsed chimney in-situ blasting demolition method
The invention discloses an in-situ blasting demolition method for a symmetrically folded collapsed chimney. The in-situ blasting demolition method comprises the steps that structural defects existing on a chimney cylinder body are treated; a plurality of blasting notches are axially formed in the cylinder wall of the chimney; a plurality of rows of blast holes are drilled in the range of each blasting notch, each blast hole is filled with explosives, and the explosives in the blast holes are connected with detonators; detonators are connected to form a same-network detonating network, and the detonating sequence and delay time of the detonating notches with different heights are set; and protection equipment is arranged, blasting notches at different heights are protected, and a blasting network of the same blasting network is excited and detonated. The in-situ blasting demolition method for the chimney is small in space influence range, small in pretreatment and punching workload, safe and stable in chimney collapse process, small in blasting adverse effect and wide in application.
本发明公开一种对称折叠坍塌的烟囱原地爆破拆除方法，包括对所述烟囱筒身上存在的结构缺陷处进行处理；烟囱的筒壁上轴向开设若干个爆破切口；在每个爆破切口范围内钻凿多排炮孔，在每个炮孔内装填炸药，并将各炮孔内炸药与雷管连接；将雷管连接形成一个同网起爆网路，并设置不同高度爆破切口的起爆顺序与延期时间；布置防护设备，对不同高度处的爆破切口进行防护，激发起爆同网起爆网路。本发明提供了一种空间影响范围小、预处理及打孔工作量较少、烟囱倒塌过程安全稳定、爆破不利效应较小、应用广泛的用于烟囱的原地爆破拆除方法。
