高寒高海拔螺旋式隧道施工中空气质量控制

On air quality control in high and cold high-elevation spiral tunnel construction

结合工程实例,通过分析螺旋式隧道通风中存在的问题,提出了压入式通风方式,并对压入式通风系统的设置进行了阐述,最后针对高寒高海拔螺旋式隧道通风中存在的问题提出了解决方法,以确保洞内安全绿色施工。

Combining with the engineering cases,the paper points out the forced ventilation means by analyzing the problems in the spiral tunnel ventilation,illustrates the allocation of the forced ventilation system,and indicates the solutions to the problems in the high and coal high-eleva-tion spiral tunnel ventilation,so as to ensure the safe and green construction of the cave.
