介绍了采用控制爆破技术拆除大型连体水泥筒仓群的设计、施工及爆破效果。由于筒仓群周围环境比较复杂 ,因而对爆破震动、塌落冲击和爆破飞石等因素的控制要求较高 ,设计中通过对诸多因素进行分析 ,决定对大型连体筒仓群采用分割施工 ,分二次进行定向爆破拆除。采用非电导爆系统与电雷管组成的复合联接的秒差起爆网络 ,使爆破完全达到预期目的 ,为今后的同类工程提供了可借鉴的经验
The design, construction and blasting effects of the demolition of large conjoined cement silos using controlled blasting technology are described. Because the surrounding environment of the silo complex is relatively complex, the control requirements for blasting vibration, slump impact, blasting flying rock and other factors are relatively high. Through the analysis of many factors in the design, it is decided to adopt the split construction for the large-scale Siamese silo group. The second stage of directional blasting demolition. The second-second difference of the composite connection consisting of non-electrical implosion system and electric detonator is used to detonate the network so that the blasting can fully achieve the intended purpose, providing lessons for similar projects in the future.
