摘要(Abstract):
介绍了山西娘子关发电厂100m高钢筋混凝土烟囱在爆破环境极其复杂、倒塌场地十分狭窄的条件下,通过精心设计爆破方案,选择倒梯形爆破切口、正方形布孔,优化爆破参数,采取接力复式簇联起爆网路,以及精心组织施工、采取有效的安全防护等措施,确保了高烟囱定向爆破拆除圆满成功。
The present paper introduced a chimney demolition case conducted in a power plant in Shanxi Niangziguan.The chimney,standing at 100 meters-high and being in reinforced concrete structure,was erected in a very complicated environment which was so narrow that there was not much area for the collapse.And for this reason dedicated bursting program should be designed,including the selection of reverse trapezia blasting cut,the optimization of blasting parameters,square hole arrangement,the employment of relay penthouse cluster ignition network,and careful organization and construction plus effective protective measures.The blasting demolition of the chimney was very successful owing to the dedicated design.
