摘要
水工隧洞钻爆施工过程中经常发生飞石打击事故,造成人员伤亡及设备、建筑等财政受到损失,影响施工进度和建设投资,在钻爆施工过程防治飞石打击已成为水工隧洞施工安全管理中一项重要内容。文章通过对辽宁省某在建隧洞输水工程支洞爆破进洞过程中对爆破飞石成因的分析研究,总结行之有效的防护措施。
Flying Stone Strike Accidents often occur in the process of drilling and blasting construction of hydraulic tunnels,resulting in casualties and financial losses of equipment and buildings,affecting the construction progress and construction investment,preventing Flying Stone Strike in the process of drilling and blasting construction has become an important content in the safety management of hydraulic tunnel construction.Based on the analysis and research of the origin of blasting flying stone during blasting into a branch hole of a water conveyance project under construction in Liaoning province,the paper summarizes the effective protective measures.
