Abstract (en)
[origin: WO2007082519A1] The invention relates to a method for producing railway tracks of the ballastless track-type that are not entirely supported, especially for the reconstruction of existing railway systems. According to said method, foundations are introduced into the soil at predetermined intervals along the railway track, especially in the form of injection piles, the soil is dug out down to a predetermined level and caissons are positioned at least in the area above the previously introduced foundations. The soil inside the caissons is removed down to a further level while simultaneously lowering the caissons, thereby producing an excavation, a transverse girder is functionally connected to the foundation, especially the injection piles, and said transverse girder is connected in a subsequent step to the longitudinal girders which support the track that is not entirely supported.
