A method for driving a sheet pile (10) into the ground comprises the steps of providing a sheet pile (10) comprising at least one sheet pile interlock (14) having an interlock chamber (20); inserting an obturating device (16) into said interlock chamber (20); driving said sheet pile (10) into the ground; withdrawing said obturating device (16) from said interlock chamber (20). Important features of the method are that said obturating device (16) comprises an inflatable tube (21); that said inflatable tube (21) is inflated after said obturating device (16) has been inserted into said interlock chamber (20) and before said sheet pile (10) is driven into the ground; and that said inflatable tube (21) is again deflated before it is withdrawn from interlock chamber (20).

L'invention concerne un procédé d'enfoncement d'une pile de feuilles (10) dans le sol. Ce procédé consiste à mettre en place une pile de feuilles (10) comprenant au moins un élément de verrouillage de pile de feuilles (14) possédant un logement de verrouillage (20), à insérer un dispositif obturateur (16) dans le logement de verrouillage (20), à enfoncer la pile de feuilles (10) dans le sol, à retirer le dispositif obturateur (16) du logement de verrouillage (20). Le procédé de l'invention présente des caractéristiques importantes, notamment, le fait que le dispositif obturateur (16) comporte une tube gonflable (21), que ce tube (21) est gonflé après que le dispositif obturateur (16) a été inséré dans le logement de verrouillage (20) et avant que la pile de feuilles (10) ne soit enfoncée dans le sol, et qu'il (21) soit à nouveau dégonflé avant son retrait du logement de verrouillage (20).
