摘要
介绍了衡阳市闹市区高架桥爆破拆除工程。针对高架桥长度大、桥跨多、环境复杂、工期短和安全要求高的特点,采取密孔钻爆方式、分层轴向空气间隔装药结构、双向多段不等差延时起爆技术和严密的安全防护措施,取得了理想的爆破效果。
This essay introduces a viaduct demolition project in a busy street. In accordance with factors such as the big length of the viaduct and the great number of its spans, limited working hours and tight security, we adopted such techniques as dense drilling, an axially layered charge structure with layers of air, and bi-directional and multisectional detonating delayed with a varied time difference, along with tight security protection measures, so ideal demolition effects are achieved.
