The present invention relates to a structure for eliminating flow bottleneck phenomenon of the main line of an urban railway. The present invention has a characteristic of connecting: the entrance of a vertical vent, which vertically penetrates and connects the gap between a main line tunnel where a railway vehicle is moving and the ground; and the ceiling of the main line tunnel towards a streamline- shaped guide unit. The present invention has an effect of preventing the bottleneck phenomenon of air flow and increasing ventilation efficiency by connecting the entrance of the vertical vent and the ceiling surface to the streamline-shaped guide unit and by guiding air to an air passage through the streamline-shaped guide unit of the vertical ventilation unit. |
