120t水塔定向爆破拆除

The Controlled Blasting of a 120-ton Water Tower

介绍运用对称三角形定向窗 ,双倒梯型爆破切口控制爆破技术 ,成功地拆除复杂环境条件下的砖混结构 12 0 t级水塔的实例 ,阐述了拆除爆破设计、施工及所采取的技术措施 ,用“压屈型”

In this paper, the controlled blasting technology which involves directional symmetry triangle window and double trapezoidal cutting are applied to demolish a 120-ton water tower of brick mixed structure in the complicated surroundings.The designing and executing measures are introduced also.A new toppling mechanism-'compressive yielding' is used to explain the casting distance of similar engineering.
