The present invention relates to a structure used to eliminate the flow bottleneck phenomena in a vertical ventilation inlet of a subway tunnel in an urban railway system. The present invention connects a vertical ventilation inlet penetrating the space between a subway tunnel where a railway vehicle moves onto and the ground and the ceiling of the subway tunnel with a wired guide unit. The present invention connects the vertical ventilation inlet and the ceiling surface with the wired guide unit to guide the air to flow through the wired guide unit to an air flow path to prevent the flow bottleneck phenomena in the air flow to increase the efficiency of the ventilation. The present invention ensures high ventilation to enable a low- capacity ventilation apparatus to be installed to lower the load applied on the vertical ventilation opening and lower the power consumption by driving the low- capacity ventilation apparatus. |
