摘要
针对朱旺沱宾馆倒塌长度有限,周围建筑及物品抗震性能较差的实际情况,采用单向三折叠爆破技术;对爆破切口处的梁以及切口外立柱、梁进行钻孔松动破坏;通过捆扎胶皮网、开挖多条减震沟、铺设柔性缓冲层的方法对爆破飞石、触地振动进行了控制,爆破拆除达到了预期效果。
The length for collapsing of Zhuwangtuo building is limited and the seismic resistance of bottles wine around is poor,so the building was demolished with three unidirectional folding and the roof beam in blast area and the column and roof beam near blast area were loosen. Some measures were taken to control the blast fly-rock and the ground vibration, such as the banding rubber network, digging damping ditch and laying flexible buffer layer were involved.
