【摘要】 介绍一大型水泥厂筒仓结构物群体的定向爆破拆除,但需保留其中一磨料房和6个筒仓。由于筒仓群周围环境复杂,筒仓集群连接,结构坚固,难以实现定向倒塌。该工程采用预处理办法,将其分割成3组独立的结构群体,分组顺序延时起爆,分别向三个方向倾倒的“同一建筑三向倾倒方案”。爆破后达到预期的拆除目的,可为同类工程参考。更多还原

【Abstract】 In this paper,a very large cement factory building need to be demolished,but the triturator house and the rest six silos must be protected.Because of the complicated environment and the stable structure,and it is difficult to topple them over.Based on some pre-treatment measures such as dividing them into 3 separated structures and priming them in sequence,three different directional collapsing of the same construction is realized.The desired blasting results were achieved and the experience could been provided for similar projects in the future.更多还原
