公路长隧道施工通风技术分析

Technical Analysis of Ventilation During Construction of Long Highway Tunnel

从风量计算、风机和风管选型与布置、通风效果检测及评价等几个方面对昆石高速公路阳宗隧道的施工通风实例进行了分析论证,实践证明:阳宗隧道施工通风系统效果良好。

The ventilation technology of long highway tunnel was analyzed in combination with the actual project of Yangzong Tunnel on Kunming-Shilin Expressway in aspects of air volume calculation, selection and deployment of draught fan and air hose, detection and appraisal of ventilation effect. The practice shows that the ventilation system applied by Yangzong Tunnel works fine.
