Vacuum tube railway system
Vacuum tube railway system comprising a vacuum tube (18) mounted on a ground support (4), a magnetic levitation railway track (10) mounted inside a wall (20) forming the vacuum tube (18) for guiding a magnetic levitation railway vehicle (8), the vacuum tube (18) assembled in sections along the ground support, at least some of a plurality of sections of vacuum tube being coupled together by a dilatation joint (22) configured for hermetically sealing a dilatation gap between said sections of tube. The dilatation joint (22) comprises at least first and second support plates (26a, 26b) mounted on an outer surface of the tube wall (20), a first support plate fixed to a first section (18a) of vacuum tube and a second support plate (26b) being fixed to a second section (18b) of vacuum tube, the support plates extending longitudinally over the dilatation gap over a length (L1) greater than a maximum dilatation gap (G), the first and second support plates being slidably mounted with respect to the other, the dilatation joint further comprising an elastic sealing layer (30) extending over an outer side of the support plates.The sealing layer is bonded to the outer surface of the wall and extends fully over the support plates,configured to hermetically seal the dilatation gap when the pressure inside the vacuum tube is lower than atmospheric pressure.
