摘要
在需保护建筑物很近,倒塌方向受限的复杂环境且烟道口部分位于切口范围内的不利条件下,通过对爆破参数、安全防护等进行周密设计与施工,成功对烟囱实施定向拆除爆破,飞石与震动得到了良好控制,拆除与防护效果均令人满意。为今后在苛刻条件下进行控制拆除爆破积累了经验。
By carefully designing the blasting parameters and implementing with safe protection and so on,the directional blasting of a chimney was implemented successfully in complex environment that the near buildings must be protected,the fallen direction is limited,the flue is partly in cut scope and so on.Flyrock and vibration are under good control.The effectiveness of demolition and protection is satisfactory.Much practical experience is accumulated for similar cases of controlled blasting demolition in future.
