Title (EN) PIPELINE PADDING APPARATUS
(FR) APPAREIL DE REMPLISSAGE DE TRANCHEES DE PIPELINES
Abstract:
(EN) A backhoe operated bucket (10) is provided with an opening containing a screen frame opposite its scraper blade, with a loading opening for separating coarse material contained in the soil excavated from a pipeline ditch (16), and depositing fine padding soil (20) on a pipeline (18) in the ditch (16). A motor driven eccentric supported by the screen frame vibrates the screen frame in several directions to achieve a separation of fine and coarse material, the latter being deposited in the ditch (16) above the padding soil.
(FR) Un godet (10) manoeuvré par un tractopelle est pourvu d'une ouverture comportant une caisse de crible, à l'opposé de sa lame niveleuse, équipée d'un orifice de chargement destiné à séparer d'autres matériaux le gros matériau contenu dans le sol excavé d'une tranchée de pipeline (16) et à déposer une terre de remplissage à grain fin (20) sur un pipeline (18) au fond de la tranchée (16). Un excentrique à moteur monté dans la caisse de crible fait vibrer celle-ci dans plusieurs directions afin de finir de séparer le matériau à grain fin du gros matériau, ce dernier étant déposé dans la tranchée (16) au-dessus de la terre de remplissage.
