Abstract
Structure for the provisional support of a railway line during excavation under the line, in particular during the construction of an underpass. The structure comprises at least one pair of main beams 10 arranged in parallel and external to the rails 2 and a plurality of secondary beams 20, each of which extends transversally to the rails 2 and is supported by two main beams 10. Each secondary beam 20 is located under the rails 2 in the space defined between two adjacent sleepers and has a top surface for resting the rails which is substantially contained in the plane defined by the top faces of the sleepers.
