Anti-backseat impact-reducing blasting demolition method for high-rise building
The invention discloses an anti-backseat impact-reducing blasting demolition method for a high-rise building, and the method comprises the steps: dividing a buffer region with a preset height at the bottom of a building body, and dividing a collapse blasting notch in the buffer region; the non-bearing components, the elevator shaft and the building body in the buffer area and the collapse blasting notch range are treated; the load-bearing component needing to be blasted and the blasting height are calibrated in the collapse blasting notch, and drilling and explosive charging are conducted; a buffer notch is divided in the buffer area, and drilling and charging are conducted on the bearing component within the range of the buffer notch; network connection is carried out on the collapse blasting notches filled with the explosive and the buffer notches, and the detonation delay time of all the construction rooms is set; the buffer area, the explosive loading part in the collapse blasting notch range and the free face of the building are protected, and the collapse blasting notch detonation network is detonated, so that the building is unstable and collapsed; and after the upper body of the building body is collapsed, the buffer notch detonation network is detonated, and the rear-seat-preventing and impact-reducing blasting demolition of the high-rise building is achieved.
本申请公开了一种高层楼房防后座减冲击的爆破拆除方法，所述方法包括：在楼房楼体底部划分出预设高度的缓冲区域，在缓冲区域划分倒塌爆破切口；将缓冲区域与倒塌爆破切口范围内的非承重构件、电梯井和楼体进行处理；在倒塌爆破切口内标定出需要爆破的承重构件与爆破高度，并进行钻孔装药；在缓冲区域内划分出缓冲切口，并在缓冲切口范围内的承重构件上进行钻孔装药；对填药后的倒塌爆破切口与缓冲切口进行网路连接，并设置各个构建间的起爆延期时间；对缓冲区域、倒塌爆破切口范围内装药部位、建筑物临空面进行防护，引爆倒塌爆破切口起爆网路，使楼体失稳倒塌；待楼体上体倒塌完毕，引爆缓冲切口起爆网路，实现高层楼房防后座减冲击的爆破拆除。
