摘要(Abstract):

上面是钢筋混凝土罐体、下面是框架支撑的料仓类建筑物,由于自重过大,定向倒塌时往往会发生严重的坐塌和后坐现象。本文通过济钢焦化厂连体群仓爆破实践,介绍了中排立柱爆破切口二次形成和在后排立柱根部安装"防后坐钢支架",防止了坐塌和后坐的成功做法,可供类似工程参考和借鉴。
The top of the subject is reinforced concrete silos and the bottom is built to be frame-braced storages.Owing to its too heavy self-weight,critical vertical collapse and recoil usually occurs in directional blasting.The author introduces methods of second formation of blasting notch on the central pillars and installation of anti-recoil bracket on the rear pillars to avoid vertical collapse and strength of push-back.The work done in this paper is of reference value to the similar engineering.
