Title (EN) METHOD AND DEVICE FOR COMPACTING A TRACK BALLAST BED
(FR) PROCÉDÉ ET DISPOSITIF POUR COMPACTER UN BALLAST
(DE) VERFAHREN UND VORRICHTUNG ZUM VERDICHTEN EINES GLEISSCHOTTERBETTS
Abstract:
(EN) Disclosed is a method for compacting a track ballast bed (2) by means of a tamping unit (1) comprising two opposite tamping tools (6) which, during a tamping process, are lowered into the track ballast bed (2) while being made to vibrate and are moved towards one another using a lateral movement. According to the invention, at least one variable vibration parameter (16, 23) is predefined in accordance with a penetration time (13) into the track ballast bed (2) until a required penetration depth of the tamping tools (6) has been reached.
(FR) L'invention concerne un procédé pour compacter un ballast (2) au moyen d'une unité de bourrage (1) comprenant deux outils de bourrage (6) opposés qui, lors d'un processus de bourrage, sont soumis à une oscillation, abaissés dans le ballast (2) et déplacés l'un vers l'autre au moyen d'un mouvement de mise en place. Au moins une grandeur d'oscillation (16, 23) variable est prédéfinie en fonction d'une durée de pénétration (13) dans le ballast (2) jusqu'à ce qu'une profondeur de pénétration requise des outils de bourrage (6) soit atteinte.
(DE) Verfahren zum Verdichten eines Gleisschotterbetts (2) mittels eines Stopfaggregats (1), das zwei gegenüberliegende Stopfwerkzeuge (6) umfasst, die bei einem Stopfvorgang mit einer Schwingung beaufschlagt in das Gleisschotterbett (2) abgesenkt und mit einer Beistellbewegung aufeinander zubewegt werden. Dabei ist vorgesehen, dass zumindest eine variable Schwingungsgröße (16, 23) in Abhängigkeit einer Eindringdauer (13) in das Gleisschotterbett (2) vorgegeben wird, bis eine geforderte Eindringtiefe der Stopfwerkzeuge (6) erreicht wird.
