摘要
介绍了复杂环境下150 m高钢筋混凝土烟囱的爆破拆除。采用复式梯形切口,水钻切边、试爆开窗、预留支撑体,爆破时只炸支撑体而使烟囱定向倾倒。通过精心设计和施工取得了定向准确、倾倒落地安全、爆破危害控制好的爆破效果。
The explosive demolition of 150 m high reinforced concrete chimney on complex environment was introdeced.The blasting design used composite blast gap,cutting by rotarywash-boringequipment,test-blasting and reserving support body and only broken the support body in the final.The well design and construction were used to achieve the sucessful practice with accurate direction,safe collapsion and well controlled blasting harzard.
