爆破拆除紧邻道路钢筋混凝土基础的安全控制

Safety controlling on blasting demolition for reinforced concrete foundation close to roadway

在泰安市道路改扩建工程中,针对某楼房基础实施控制爆破拆除,通过选择合适的爆破参数、装药结构和起爆顺序,探讨了紧邻道路及其他电力通讯设施的复杂环境下控制爆破拆除技术,严格控制了爆破震动和飞石,保证了房屋设施的安全,取得了良好的爆破效果,为类似爆破工程提供了施工经验。

The controlled blasting is adopted for the reinforced concrete foundation of a building. Based on the selection of the suitable blasting parameters and the loaded constitution, the reasonable firing method and detonation sequence of the blasting demolition engineering close to roadway are put forward. The techniques of millisecond blasting and safety measures of reducing vibration and controlling blasting flying rock are put forward. The house and establishment is safe after blasting. The explosive effect is satisfactory. The experience provides the reference for the similar blasting engineering.
