Definitions

  • Foundation piles 40 ordered in a geometric pattern can be arranged in an underwater bottom 30 with positioning framework 1.
  • the shown embodiment of device 10 comprises a floating body in the form of a pontoon, or the shown combi-float 11, which is assembled from a number of (21) pontoons connected together.
  • the chosen dimensions of combi-float 11 in transverse directions X and Y are smaller than the transverse distance between guide tubes (2a, 2b, 2c, 2d) of positioning framework 1.
  • Combi-float 11 further has sufficient buoyancy to float on a water surface 32 during use.
  • Combi-float 11 can be carried to a desired location by a vessel using towing cables 28.
  • Combi-float 11 is provided with anchor means in the form of four traction cables 12, which are provided at an outer end with anchors (not shown) for engagement with underwater bottom 30.
  • Guide tubes (2a, 2b, 2c, 2d) can also take a sound-damping form, which can for instance be achieved by giving the tubes (2a, 2b, 2c, 2d) a double-walled form and introducing air between the two walls from below.
  • Guide tubes (2a, 2b, 2c, 2d) are further preferably provided on an upper side with inlet funnels (6a, 6b, 6c, 6d) for a pile 40 to be received.
  • the conical contact surface 27 on the one hand provides sufficient fixation of the underside of guide pillar 15 to underwater bottom 30, but on the other allows a rotation of guide pillar 15 around axes X and Y running perpendicularly of a longitudinal axis 15a of guide pillar 15.
  • a rotation Ry around the Y-axis is shown in figure 7
  • figure 8 shows a rotation Rx around the X-axis.
  • the rotations Rx and Ry can be obtained by tightening and/or paying out traction cables 12, whereby pontoon 21 is displaced through a relatively small distance and guide pillar 15 rotates around the X-axis and/or the Y-axis.
  • Guide pillar 15 can in this way be placed in a precisely determined vertical position, wherein longitudinal axis 15a runs parallel to the vertical direction Z.

Claims (17)

  1. Dispositif (10) permettant de transporter sous l'eau un cadre de positionnement (1) qui est configuré pour agencer dans un fond sous-marin (30) des pieux de fondation (40) agencés suivant un motif géométrique, le dispositif (10) comprenant un corps flottant (11) ayant une flottabilité suffisante pour flotter sur une surface aquatique (32) et doté de moyens d'ancrage (12) qui peuvent garder le corps flottant (11) en place par rapport au fond sous-marin (30), et une structure de guidage allongée (15) pour le cadre de positionnement (1) qui est reliée au corps flottant (11) et peut être abaissée jusque sur le fond sous-marin (30), caractérisé en ce que la structure de guidage comprend, sur une face inférieure de celle-ci, un moyen de support (17) qui fixe la face inférieure dans le fond sous-marin (30) et autorise une rotation autour d'un axe (x, y) perpendiculairement à un axe longitudinal (15a) de la structure de guidage (15).
  2. Dispositif selon la revendication 1, dans lequel un cadre de positionnement est relié rigide à la structure de guidage et est situé sous le corps flottant.
  3. Dispositif selon la revendication 1, dans lequel un cadre de positionnement est relié à la structure de guidage pour être déplacé suivant l'axe longitudinal de la structure de guidage et est situé sous le corps flottant.
  4. Dispositif selon l'une quelconque des revendications précédentes, dans lequel la structure de guidage est reliée au corps flottant au moyen d'une liaison pivotant autour d'un axe courant perpendiculairement à un axe longitudinal de la structure de guidage.
  5. Dispositif selon la revendication 4, dans lequel la structure de guidage est reliée au corps flottant au moyen d'une liaison pivotant autour de deux axes courant perpendiculairement à un axe longitudinal de la structure de guidage.
  6. Dispositif selon l'une quelconque des revendications précédentes, dans lequel la structure de guidage est reliée au corps flottant au moyen d'une liaison qui, par rapport au corps flottant, n'autorise sensiblement aucune rotation de la structure de guidage autour d'un axe courant parallèlement à l'axe longitudinal de la structure de guidage.
  7. Dispositif selon l'une quelconque des revendications précédentes, dans lequel la structure de guidage est reliée au corps flottant dans une position centrale d'un pont de travail du corps flottant.
  8. Dispositif selon l'une quelconque des revendications précédentes, dans lequel le moyen de support de la structure de guidage autorise une rotation autour de deux axes courant perpendiculairement à l'axe longitudinal de la structure de guidage.
  9. Dispositif selon l'une quelconque des revendications précédentes, dans lequel les moyens d'ancrage sont configurés pour faire tourner la structure de guidage autour d'un axe perpendiculairement à un axe longitudinal de la structure de guidage.
  10. Dispositif selon la revendication 9, dans lequel les moyens d'ancrage comprennent des câbles de traction qui sont dotés d'ancres et qui peuvent être tendus au moyen de treuils montés sur le corps flottant, et la résultante des contraintes des câbles de traction ne passe pas par l'axe longitudinal de la structure de guidage.
  11. Dispositif selon l'une quelconque des revendications précédentes, dans lequel le moyen de support comprend une surface conique de contact avec le fond sous-marin.
  12. Dispositif selon l'une quelconque des revendications précédentes, dans lequel le moyen de support comprend une surface sphérique de contact avec le fond sous-marin.
  13. Dispositif selon la revendication 2 ou 3, dans lequel le cadre de positionnement comprend des tubes de guidage reliés entre eux pour les pieux de fondation agencés suivant le motif géométrique.
  14. Dispositif selon la revendication 13, dans lequel l'axe longitudinal de la structure de guidage s'étend de façon sensiblement parallèle à un axe central des tubes de guidage.
  15. Dispositif selon la revendication 13 ou 14, dans lequel les tubes de guidage comprennent un corps allongé d'une longueur telle qu'ils s'étendent au-dessus de la surface de l'eau pendant leur utilisation.
  16. Dispositif selon l'une quelconque des revendications 13-15, dans lequel les tubes de guidage sont insonorisants.
  17. Procédé d'agencement, dans un fond sous-marin, de pieux de fondation disposés suivant un motif géométrique, comprenant les étapes consistant :
    - à réaliser un dispositif selon l'une quelconque des revendications précédentes ;
    - à garder le corps flottant en place par rapport au fond sous-marin au moyen des moyens d'ancrage ;
    - à abaisser un cadre de positionnement relié à la structure de guidage en direction du fond sous-marin jusqu' à une position de travail, étant entendu que le moyen de support fixe la face inférieure de la structure de guidage dans le fond sous-marin, et
    - à battre les pieux dans le fond sous-marin à travers les tubes de guidage du cadre de positionnement dans la position de travail.
