多层建筑物不对称控制爆破拆除

Demolishing the multistory buildings by non-symmetrical controlled blasting

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 for a five_story building with masonry concrete in Jiaozuo Brake Plant demolished by the controlled blasting has been introduced. In order to ensure the safty of the buildings which should be kept and reduce the vibration of the explosion and shock of the buildings that are falling to the ground with breaks, the nonel ignition system and the skill of delay ignition in the hole and out of the hole and the non_symmetrical controlled blasting measures have been performed. Thus, a desired result is obtained.
