Title (EN) STEEL RAILWAY SLEEPERS
(FR) TRAVERSES DE CHEMIN DE FER EN ACIER
Abstract: front page image
(EN)A steel railway sleeper of inverted 'U' cross-section whose upper surface and/or one or both side surfaces and/or one or both spade ends are formed with openings through which stone ballast can be injected. The openings are at least partially bordered by deflector plates, which project into the sleeper interior and are positioned to direct pneumatically injected stone ballast towards a predetermined area within the sleeper interior.
(FR)L'invention concerne une traverse de chemin de fer à section en U inversée, dont la face supérieure et/ou une face latérale ou les deux, et/ou une extrémité bêche ou les deux comprennent des orifices, à travers lesquels un ballast en pierre peut être injecté. Lesdits orifices sont, au moins en partie, bordés par une plaque de déviation qui fait saillie à l'intérieur de la traverse et sont positionnés pour diriger de manière pneumatique le ballast en pierre injecté vers une zone prédéterminée à l'intérieur de la traverse.
