摘要:
介绍了全剪力墙结构楼房的定向爆破拆除。根据楼房剪力墙特点和周围环境,选择向北部空地定向倒塌的爆破方案,对1~4层剪力墙、楼梯进行局部预拆除;选择三角形爆破切口,采用四通与“大把抓”相结合的复式起爆网路,整体对角式延时起爆技术,实现大楼剪切解体;采用主动防护与被动防护相结合的安全防护技术,有效地控制爆破振动、塌落振动和爆破飞散物,取得了良好的爆破效果。
Abstract:
Blasting demolition of a building with full shear wall structure was introduced. Directional collapse to an open space in the north was selected according to characteristics of the shear wall and the surrounding environment. Partial shear wall and stairs in 1-4 layers were pre-demolished, whereas the main body was shear-disintegrated using triangular incision, multiple detonation network which was a combination of four way pipe with large packing, and the whole diagonal type delay initiation technology. An excellent blasting result was achieved due to the usage of combined safety protection technology of active protection and passive protection, and effective control of blasting vibration, collapse vibration and scattered blasting material.
