摘要
在对一座石砌水塔爆破拆除中 ,因风化较重而无法开设定向窗和掏槽洞 ,设计时利用偏离定向倒塌方向的水塔门口 ,采用对称梯形开口 ,非对称起爆程序等措施 ,达到了预期爆破效果。
The directional windows and cutting holes could not be made due to serious weathering in blasting demolition of a stone-structure water tower. A natural gate of the water tower away from the direction of collapsing was utilized in the program design. The measures such as adopting symmetric trapezoid collar and asymmetric detonation sequence were taken to get an anticipated blasting effectiveness.
