介绍了焦作市制动器厂五层砖混结构楼房控制爆破拆除的设计与施工 .为确保保留建筑物的安全、加强钢混构件落地后的破碎和控制爆破地震、塌落地震 ,采用非电孔内、孔外延时起爆和不对称控制爆破技术 ,形成了建筑物分段跨落 ,达到了预期的效果 . The design and construction of the controlled blasting demolition of the five-story brick-concrete structure building of the Jiaozuo City Brake Factory was introduced. To ensure the safety of the preserved building, to strengthen the crushing of the steel-concrete components after landing, and to control the blasting earthquake and slumping earthquake, the non-electromagnetic hole was used. The explosion of the hole and the asymmetrical controlled blasting technology have formed a segmented structure and achieved the desired effect.
