VENTILATION OF AN UNDERGROUND RAILWAY WITH SINGLETRACKED SHIELD TUNNELS

To work out countermeasures for the expected annual increase of air temperature in the station and tunnel spaces of underground extensions, Shinagawa-Ryogoku, of Tokaido and Sobu Lines, the existing underground railway lines have been surveyed; and to realize a ventilation system of longitudinal stream type, theoretical and experimental studies have been made. The present paper gives a generalized statement of the results of research. Ventilation of a longitudinal stream type is recommended as appropriate for the underground railway with single-tracked shield tunnels. Capacity for the ventilator to be employed, special conditions calling for attention in the construction, new idea in the air conditioning of station space are made clear with design examples cited. The paper also refers to the pollution of the external air to be used for ventilation and to the background noise of ventilator installations.
