公路隧道运营通风效果现场实测与分析

Analysis and field survey about operation ventilation effect of highway tunnel

采用 CO- 1 A型 CO气体检测报警仪对某隧道内空气中 CO浓度进行了实测 ,测试结果表明在通风系统正常工作的状态下 ,隧道内空气中 CO浓度远小于设计值 ,能保持隧道内良好的空气。同时 ,采用 SL- 40 0

Based on CO gas detection warning instrument of CO-1A type, CO concentration in air was surveyed on some tunnel. This test effect shows CO concentration value in air about the tunnel is far smaller than designed value in normal working condition of ventilation system, as a result, air quality is good in the tunnel. In addition, the tunnel noises were tested through sound level meter of SL-4001 type.
