摘要
作者采用控制爆破技术拆除复杂环境下钢筋混凝土框架结构物。设计与施工中,通过分析钢筋的失稳条件确定了立柱炸高,采用半秒延期雷管组成非电复式闭合起爆网路,使用多层遮挡和覆盖进行飞石防护控制,使拆除爆破达到了预期效果。
In this paper, the controlled blasting technique is adopted to demolish reinforced concrete frame structure in complicated surroundings. During the process of design and construction, the frame stand-off is determined through analyzing the destabilizing conditions of reinforced steel bar. The half-second delay detonators are used to compose a non-electric, compound and closed initiation net, multi -shelter and overcast are also adopted to defend from slung shot, consequently the prospective effect is achieved by demolition blasting and the ambient buildings are all safe and sound.
