With four traffic lanes between Hanwa Expressway Kainan - Arida, I examined remodeling about ventilation facilities of 3 tunnels of Fujishiro / Shimotsu / Nagamine. I examined foul air exhausted by vertical shaft method that used an existing shaft at first, but examined a ventilation method by up and down line separation because there was not it by the economic facilities construction. It was the production center of famous "Arida mikan" nationwide, and the area concerned did not have to become worse than the present conditions about the discharge of the soot from the tunnel. Therefore, I installed an electrostatic precipitator in the tunnel of the line II .The tunnel of the line I planned foul air exhausted by vertical shaft method that used an existing shaft. But because there was not a place to put JF into the Nagamine tunnel, I made ventilation place at the exit and installed an electrostatic precipitator. The targeted value to ventilation control assumed it a discharge of the SPM. The program to use adopted MPVC and aimed at the effective ventilation use.
