Blasting demolition method for cyclone furnace
The invention relates to a demolition method for a high-gravity-center steel frame building, and particularly discloses a cyclone furnace blasting demolition method which comprises the following steps: (1) demolition of a non-bearing wall body of a concrete frame structure; (2) the concrete frame structure is divided into front-row stand columns and rear-row stand columns according to the dumping direction; (3) when the designed height of the front-row stand column notch is larger than that of the concrete frame structure, semi-cutting damage is conducted on a steel pipe inclined strut of the steel pipe frame structure on the upper portion of the concrete frame structure; (4) blast holes are drilled in the notch design range of the stand column and the blasting points on the tie beam and filled with explosives, and the blasting unit consumption is controlled to be 1.0 Kg/m < 3 > or above; and (5) setting the span of the front-row upright post and the rear-row upright post to be Xm, setting the delay time of the detonator in the blast hole of the front-row upright post to be 0ms and the delay time of the detonator in the blast hole of the rear-row upright post to be 50-85Xms when the explosive is ignited. According to the scheme, a controlled blasting mode is adopted to solve the problem of safe dismantling of the large-structure and high-gravity-center decomposing furnace of the cement plant.
本申请涉及高重心钢架建筑的拆除方法，具体公开了旋风炉爆破拆除方法，其包括如下步骤：(1)拆除混凝土框架结构的非承重墙体；(2)根据倾倒方向将混凝土框架结构分为前排立柱和后排立柱；(3)前排立柱切口设计高度大于混凝土框架结构时，在混凝土框架结构上部对钢管框架结构的钢管斜撑进行半切割破坏；(4)在立柱的切口设计范围内和系梁上的爆破点钻出炮孔，并装填炸药，爆破单耗控制在1.0Kg/m3以上；(5)前排立柱和后排立柱的跨度为Xm，起爆炸药时，前排立柱的炮孔内的雷管延期时间设置为0ms，后排立柱的炮孔内的雷管延期时间为50‑85Xms。本方案采取控制爆破方式解决了水泥厂大结构、高重心分解炉的安全拆除难题。
