六层教学楼拆除爆破技术

Demolition blasting technology of six-storey classroom building

采用延时定向控制爆破方法拆除六层教学大楼,针对爆破环境复杂的特点,将教学楼分为三个区延期起爆,先起爆中部,后起爆两侧,先前柱再后柱的起爆顺序,并对教学大楼做了充分的预处理,爆破后证明采用以上技术取得了理性的爆破效果。

Demolished the six-storey classroom building by delay and directional blasting, as the blasting environment was complex, the class-room building was divided into three zones and by delayed initiation, the detonation sequence was, first the middle part, then the two wing sides, first the front column, then the back column, and made a pretreatment for the whole classroom building. Blasting effect was proved that the blasting technology was rational.
