摘要(Abstract):

采用延时爆破技术一次拆除了复杂环境条件下电厂主厂房及高80m钢筋混凝土烟囱。本文针对该工程爆破拆除的技术与施工要点,介绍了爆破切口的布置、爆破参数的选取、厂房和烟囱延时起爆顺序的确定,以及预处理和安全防护措施等设计施工方案。成功的爆破经验可供类似工程参考。
The main workshop and 80m height reinforced concrete chimney were demolished simultaneously by delay blastiag under the conditions of complicated environment. This paper,referring to the key points of the technology aspect and construction,discussed the layout of blasting cuts,the determination of blasting parameters and initiation sequence of workshop and chimney,and the pretreatment and security measures concerned. The successful experience could be a valuable reference to similar projects.
