The present invention relates to a ventilation system. (70) for a fixed- guideway-based transportation network comprising at least one tunnel (31, 41, 51, 61). The ventilation system (70) comprises an air duct (33, 43, 54, 65) housed in the tunnel (31, 41, 51, 61) and configured to extract smoke, fumes and hot air (F) generated by a fire within the tunnel (31, 41, 51, 61) and to vent them to the outside of the tunnel (31, 41, 51, 61). The air duct (33, 43, 54, 65) comprises a plurality of first air vents (34, 44, '55, 66, 77) that can be operated separately and that, when open, connect the inside of the air duct (33, 43, 54, 65) with the inside of the tunnel (31, 41, 51, 61). In use, in the air duct (33, 43, 54, 65) there is a vacuum created by suction means coupled to the air duct (33, 43, 54, 65).

La présente invention concerne un système de ventilation (70) pour un réseau de transport à surface de guidage fixe, qui comporte au moins un tunnel (31, 41, 51, 61). Le système de ventilation (70) comporte une conduite d'air (33, 43, 54, 65) placée dans le tunnel (31, 41, 51, 61) et conçue pour extraire la fumée, les émanations et l'air chaud (F) générés par un incendie à l'intérieur du tunnel (31, 41, 51, 61), et à les évacuer vers l'extérieur du tunnel (31, 41, 51, 61). La conduite d'air (33, 43, 54, 65) comporte une pluralité de premières prises d'air (34, 44, 55, 66, 77) qui peuvent être actionnées séparément et qui, lorsqu'elles sont ouvertes, relient l'intérieur de la conduite d'air (33, 43, 54, 65) à l'intérieur du tunnel (31, 41, 51, 61). Lors de l'utilisation dudit système, un vide est créé dans la conduite d'air (33, 43, 54, 65) par un moyen d'aspiration accouplé avec la conduite d'air (33, 43, 54, 65).
