The invention pertains to a driver (1) for installing foundation elements, such as anchors or piles, in a ground formation and preferably in submerged condition, comprising a housing for accommodating and guiding a weight, an element for mounting the driver (1) on or in the foundation element, one or more chambers for holding a charge or one or more connectors for connecting the driver (1) to a source of a high pressure gas, and corresponding conduits allowing a high pressure gas to flow from the chamber (s) or connector (s) to below the weight. The housing is adapted to allow a stroke of the weight having a length such that, during upward movement of the weight the pressure of the gas drops to a value, which will cause the weight to decelerate.
L'invention porte sur un mouton (1) destiné à installer des éléments de fondation tels que des ancrages ou des piles dans le sol et de préférence dans des conditions de submersion. Ledit mouton comporte: une enceinte recevant une masse et la guidant; un élément élevant le mouton (1) au-dessus ou à l'intérieur de l'élément de fondation; une ou plusieurs chambres recevant une charge; un ou plusieurs connecteurs raccordant le mouton (1) à une source de gaz sous pression; et des conduits correspondants permettant au gaz sous pression de la ou des chambres ou du ou des connecteurs de passer sous la masse. L'enceinte est conçue pour que lors de la course ascendante de la masse la pression du gaz tombe à une valeur telle que la masse décélère.
