Title (EN) DEVICE FOR ESTABLISHING AN ESCAPE ROUTE IN TUNNELS
(FR) DISPOSITIF D'ÉTABLISSEMENT D'UNE VOIE D'ÉVACUATION DANS DES TUNNELS
Abstract:
(EN) It is disclosed a device for establishing an escape route inside a tunnel, wherein the device comprises a number of similar or different sections, each section comprising a substantially gas-tight and inflatable sheath comprising mainly or completely gas-impenetrable walls and that may exist in an upright or deflated condition, said section(s) in a deflated condition existing as a collapsed and preferably folded strip, said strip being capable of being supplied with a pressurized fluid so that the walls of the section(s) are extended for establishing a corridor running mainly in the lengthwise direction of the tunnel or from at least one of the tunnel openings to a permanent escape opening in the wall(s) of the tunnel or between at least two permanent escape openings in the tunnel.
(FR) L'invention concerne un dispositif permettant d'établir une voie d'évacuation à l'intérieur d'un tunnel, le dispositif comprenant un certain nombre de sections similaires ou différentes, chaque section comprenant une gaine gonflable et sensiblement étanche aux gaz comprenant des parois principalement ou complètement imperméables au gaz et qui peuvent exister dans un état vertical ou dégonflé, ladite(lesdites) section(s) dans un état dégonflé existant sous forme d'une bande affaissée et de préférence pliée, ladite bande pouvant être alimentée en fluide comprimé de telle sorte que les parois de la(des) section(s) est(sont) prolongée(s) pour établir un couloir s'étendant principalement dans la direction longitudinale du tunnel ou d'au moins l'une des ouvertures de tunnel jusqu'à une ouverture d'évacuation permanente dans la(les) paroi(s) du tunnel ou entre au moins deux ouvertures d'évacuation permanentes dans le tunnel.
