Abstract

L'invention concerne différents modes de réalisation de dispositifs pour compacter le sol se présentant sous forme de rouleaux pour le sol. Ces rouleaux se composent de dispositifs en forme de roue ou de disque qui sont disposés sur un axe commun à distance les uns des autres et dont la surface périphérique peut, dans le sens radial et/ou axial, subir une déformation élastique de foulage ou effectuer un mouvement élastique de foulage de façon à compacter le sol. Les surfaces actives des dispositifs en forme de roue ou de disque peuvent être reliées à des éléments supports qui sont conçus ou disposés de façon à pouvoir être déviés élastiquement sensiblement de tous côtés dans le sens radial et/ou axial. Il peut s'agir également d'éléments en forme de disque se présentant sous forme de disques oscillants annulaires dont le diamètre intérieur est supérieur au diamètre de l'axe, la déviation angulaire des disques oscillants étant limitée par des butées ou des appuis latéraux.
