摘要(Abstract):
介绍了定向爆破拆除复杂环境下45m高砖烟囱工程实例。通过适当地提高爆破切口高度,并采取加固爆破切口以下的烟囱壁等措施,解决了无烟囱倒塌足够长度和烟囱后坐的技术问题。同时选择了合理的爆破参数和有效的安全防护措施,使爆破取得了圆满成功。
In this paper,the demolition of a 45-meter-high brick-structured chimney in complicated environment by controlled directional blasting was introduced.Some technical measures such as heightening the position of the blasting cut and reinforcing the chimney wall under the cut were taken to solve the difficult problem of no enough space for the chimney's collapse.The paper also discussed the blasting parameters which were properly determined and the safety protection measures which were responsible for the successful blasting.
