复杂环境下砖混结构烟囱的折叠爆破拆除

Folding blasting for demolishing a brick-concrete structure chimney under complicated environment

介绍了采用2段折叠式倒塌方案,完成了一座复杂环境下砖混结构烟囱的爆破拆除。通过选取合理的爆破切口形式、孔网参数,并对烟囱爆破过程中的振动及触地震动进行了校核,采取了合理的安全防护措施,使得烟囱按照预定的方式倒塌,爆破取得了成功,可以为类似复杂环境下烟囱的爆破拆除提供参考和借鉴。

Blasting demolition of a brick-concrete structure chimney in complicated environment is carried out by using 2 section folding collapse plan. By selecting the reasonable form of blasting cut and pore network parameters, checking the vibration during basting and impact vibration and taking reasonable security protective measures, the chimney collapses in a predetermined pattern and the blasting demolition achieves success, which can provide reference for chimney demolition in similar complicated environment.
