电厂发电机组厂房及高150m烟囱定向爆破拆除

摘要

Directional blasting demolition of a generator set workshop and a 150m high chimney were introduced in a power plant whose environment was complex. Through adopting some measures such as pre-treating blasting cut of generator set workshop, cutting off some reinforcements of columns, retaining the wall of a rear row columns as anti- impact wall for blasting chimney touchdown, raising location of blasting cut of the chimney, and cutting off some reinforcements located in the support center of the chimney and so on, good blasting effect was achieved.%介绍了复杂环境下电厂发电机组厂房及高150m烟囱定向爆破拆除.通过预处理发电机组厂房爆破切口、割断立柱部分钢筋、保留后排立柱墙体作为烟囱爆破触地防冲墙,以及对烟囱爆破切口有针对性地抬高,割断烟囱支撑中心部位钢筋等措施,取得了良好的爆破效果.
