Abstract

 In order to design a suitable tunnel ventilation method among various ventilation methods in the tunnel construction site, conducting multi-point and frequent measurement of floating dust concentration and aiming to collect simply the location of dust in the tunnel by cheap and small dust sensor in this study. I have developed a simplified tunnel dust sensor by an improvement the light scattering dust concentration sensor developed for general household air purifiers. And, It was clear by simulated tunnel environmental experiments whether the developed dust sensor is suitable for measurement in a tunnel. As a result, it was found that the developed simplified tunnel dust sensor can measure the concentration generated during tunnel construction. In addition, it was also clear that the measurement results are almost the same as the digital dust sensor used for dust measurement in tunnel construction sites.
