2017年1月21日晚上11时50分,随着几声沉闷的巨响,汉口滨江商务区19栋楼成功爆破倒塌。19栋楼建筑面积高达15万平方米,创下了国内外最大的建筑裙楼爆破拆除规模。
此次爆破的19栋楼位于江岸区头道街至二七路之间,楼高7到12层,总建筑面积15万平方米,楼房紧邻解放大道和轻轨一号线,四周还有多个小区、学校、人行天桥,地下埋有高压电缆、自来水、天然气等市政管网。
全过程共历时约10秒。
据悉,这是目前国内外最大的建筑群楼爆破,现场共钻炮口12万余个,使用炸药5吨,倒塌时间精确到毫秒,解决了群楼爆破定向倒塌的问题。
此次爆破采用“一次点火,分向传递”的起爆网路,且采用高精度的非电启动,解决了世界上起爆大难题。
此次爆破后,未来这里将建起武汉第一高楼——一座707米的高楼、一条过江隧道、一个地下中心城市,有望成为汉口新中心。
