摘要
在城市内大型建筑物、构筑物拆除爆破中 ,采用大孔径钻机钻孔施工具有小孔径钻机不可比拟的优势。通过爆破方案的对比和分析 ,该方法可以加快施工速度 ,是城市工程爆破施工的有效途径。通过爆破参数、起爆网络及爆破安全的设计 ,获得了令人满意的爆破效果 ,为类似工程施工提供了经验。
In Controlled Blasting Project of large scale buildings and structures of city,the advantages of the big diameter hole drills is greatly more than the little diameter hole drills.And analyse through the contrast of demolition scheme,the speed that this method can accelerate constructing.It is the effective way of the urban project demolition.Through the design of the parameter,detonating network and the security of blasting,it has gotten the satisfactory result of demolition,and offer success experiences for blasting of similar project.
