CA 2071334

A tamping shoe for a vibration rammer has a plurality of through holes communicating between an under surface and an upper surface. The through holes permit the escape of air trapped between the under surface and a surface being tamped, and thereby reduce the amount and pressure of air compressed under the tamping shoe. This reduces noise pollution produced during tamping. In a preferred embodiment, the through holes are tapered outward in the direction of air flow. Air passing through a through hole in a mount is released through a further through hole bored through a wall of the mount.

Pied dameur pour dameuse à vibrations. Le pied dameur comporte plusieurs trous traversants assurant la communication entre une surface inférieure et une surface supérieure. Les trous permettent à l'air emprisonné entre la surface inférieure et la surface damée de s'échapper, ce qui diminue la quantité d'air et la pression de l'air comprimé sous le pied dameur, tout en réduisant la pollution par le bruit pendant le damage. Dans une application préférée, les trous traversants sont de forme conique inversée en direction du flux d'air. L'air passant par un trou traversant pratiqué dans un support s'échappe par un autre trou traversant réalisé sur une paroi du support.
