摘要
介绍了一半埋式长方形钢筋混凝土酿酒池的水压爆破拆除的工程实例。文中分析了水压爆破药量计算时经验公式和理论公式产生差异的原因,并阐述了水压爆破药量确定的方法和步骤。文章指出,当注水深度较浅时,为了不减弱装药爆炸力对器壁的冲击作用,应保证药包的入水深度不小于药包至器壁的距离。
As a practical engineering example, demolition of a semi buried reinf o rced concrete wine making rectangular pool by water pressure blasting is intr odu ced A difference between the charge weights calculated by an empiric formula a nd theoretical formula respectively is analyzed, and the method and steps for d et ermining the charge weight for water pressure blasting are expounded It is po i nted out that for less depth of water in a pool, the immersion depth of a charg e sh ould be ensured to be greater than the distance of the charge to any wall of the pool so that the shock action of explosive force on walls of a container is not weakened
