摘要
在周围环境极为复杂、倒塌场地非常狭小的条件下,采用定向爆破的方法成功地拆除了1座35m高的厚壁砖结构烟囱。通过对倾倒方向、爆破切口、爆破参数和安全控制等进行精心设计计算,开设三角形定向窗,并准确标定和准确施工,同时加强防护,确保了爆破定向准确性和周边建筑物及生产设施的安全。
By directional controlled blasting, a 35m high rick chimney under extremely complex environment and strictly collapse site was successfully demolished. Through elaborate design and calculation on topple direction, blasting cut, blasting parameters and safety control, triangle directional window was opened, accurate calibration and construction were carried out, and protection was strengthen, which ensure the accuracy of blasting direction and the safety of the surrounding buildings and production facilities.
