Abstract (en)
Method and apparatus for the construction of an underpass (30) to cross railway lines (15) with one or more tracks (11, 12), wherein a structure is used to support the tracks (11, 12) and wherein a step is provided of preparing on site foundations (16) defining a definitive position of the structure. The method provides to construct the structure (10) with a closed section whose inner volume defines the way that crosses the underpass (30), on travel ways (18) prepared at the side of said railway line (15) and associated with the foundations (16); to associate with the structure (10) containing means (20) in correspondence with the front facing towards the railway line (15); to translate the closed structure (10) by sliding it on suitable brackets along the travel ways (18), until the definitive position is reached on the foundations, and finally to return the railway line (15) to definitive operations.
