STRUCTURAL ARRANGEMENT AND PROCEDURE FOR THE STABILISATION OF LINEAR EARTHWORKS

The subject of the invention relates to a structural arrangement for the stabilisation of linear earthworks, i.e. mainly railway line superstructures, for the prevention of movements of the superstructure due to the effect of forces transverse to the direction of the trace line, whilst intermittently maintaining traffic. The invention's distinctive feature is that the load-bearing support structure is made up of a support beam (3) stabilising the ballast bed (21) and running alongside the trace line on the side of the sleepers (22) where movements tend to occur, and a supporting wall (4) located at the other side of the support beam (3) opposite the sleepers (22), extending from the superstructure (2) down towards the subsoil, and a protective blanket (5) covering the support beam (3) and the supporting wall (4), simultaneously embracing the ends (22a) of the sleepers (22) facing towards the support beam (3). The invention also encompasses the procedure for creating the structural arrangement; this procedure involves building the support beam (3) stabilising the sleepers (22), which are part of the railway superstructure, and the ballast bed (21) under them, and running alongside the trace line on the side of the sleepers (22) where movements tend to occur, and constructing, when indicated, a supporting wall (4) in the earth lying up against the other side of the support beam (3) opposite the sleepers (22), covering the support beam (3) and the supporting wall (4) with a covering blanket (5), and constructing a drain (7) underneath the supporting wall (4) if necessary. Cette invention concerne un agencement structural destiné à stabiliser des travaux de terrassement linéaires, c'est-à-dire principalement des superstructures de voie ferrée, pour la prévention de mouvements de la superstructure sous l'effet de forces transversales à la direction de la ligne de tracé, tout en maintenant le trafic de manière intermittente. L'invention est caractérisée en ce que la structure de support portante est constituée d'une poutre de support (3) stabilisant le lit de pierraille (21) et s'étendant le long de la ligne de tracé du côté des traverses (22) où les déplacements tendent à se produire, et d'une paroi de support (4) disposée de l'autre côté de la poutre de support (3) à l'opposé des traverses (22), s'étendant de la superstructure (2) vers la sous-couche, ainsi qu'une couverture de protection (5) recouvrant la poutre de support (3) et la paroi de support (4) et en
