摘要
需爆破拆除的七层楼房,为框架、砖混相结合的混合结构,楼房上部与下部,左侧与右侧其结构形式及强度均有较大差别。楼房南侧2m有架空自来水管道,周围环境复杂。为确保楼房整体定向倾倒、减小后坐,采取了能兼顾楼房上、下、左、右的爆破缺口高度差,合理的分区延期起爆时间差相结合的倾倒措施。对不同截面的钢筋混凝土柱,采取了不同的布孔形式及装药结构。爆破效果良好。
A sevenstorey building to be demolished is a mixed construction containing frame structure and brickandconcrete composite structure. The upper and lower, left and right of the structure have an evident difference in structural form and intensity. There is an aerial water pipe at the south side 2 meter, and the surrounding is complicated. To ensure its directionally collapsed and reduce the recoil, the blasting cut height which can give attention to both sides of the building and the reasonable divisional delay interval firing sequence were adopted. In accordance with differentsection reinforced concrete pillars, the different blasthole patterns and charging structure are also adopted. The blasting is effective.
