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. Vorrichtung (10) zum Halten eines sich unter Wasser befindlichen Positioniergestells (1), das zur Positionierung von Gründungspfählen (40) in einem geometrischen Muster auf einem Gewässer- oder Meeresboden (30) ausgelegt ist, wobei die Vorrichtung (10) aus einem Schwimmkörper (11) mit ausreichendem Auftrieb besteht, um auf der Wasseroberfläche (32) zu schwimmen, der mit einer Verankerung (12) versehen ist, um den Schwimmkörper (11) in einer bestimmten Position am Gewässer oder Meeresboden (30) zu sichern sowie aus einem längeren senkrechten Führungselement (15) für das Positioniergestell (1), das mit dem Schwimmkörper (11) verbunden bis auf den Gewässer- oder Meeresboden abgesenkt werden kann, dadurch gekennzeichnet, dass das Führungselement unten mit einem Stützkörper (17) versehen ist, der mit seiner Unterseite auf dem Gewässer- oder Meeresboden (30) aufsitzt und eine Drehung um eine Achse (x,y) ermöglicht, die senkrecht zur Längsachse (15a) des Führungselements (15) verläuft.
  2. Vorrichtung gemäß Anspruch 1, dadurch gekennzeichnet, dass das Positioniergestell fest mit dem Führungselement verbunden ist und unterhalb des Schwimmkörpers sitzt.
  3. Vorrichtung gemäß Anspruch 1, dadurch gekennzeichnet, dass das Positioniergestell derart mit dem Führungselement verbunden ist, dass es längs der Längsachse des Führungselements verschoben werden kann und unterhalb des Schwimmkörpers sitzt.
  4. Vorrichtung gemäß einem der vorherigen Ansprüche, dadurch gekennzeichnet, dass das Führungselement mit dem Schwimmkörper mittels einer Verbindung verbunden ist, die um eine senkrecht zur Längsachse des Führungselements liegende Achse drehbar ist.
  5. Vorrichtung gemäß Anspruch 4, dadurch gekennzeichnet, dass das Führungselement mit dem Schwimmkörper mittels einer Verbindung verbunden ist, die um zwei senkrecht zur Längsachse des Führungselements liegende Achsen drehbar ist.
  6. Vorrichtung gemäß einem der vorherigen Ansprüche, dadurch gekennzeichnet, dass das Führungselement mit dem Schwimmkörper mittels einer Verbindung verbunden ist, die praktisch keinerlei Drehung des Führungselements relativ zum Schwimmkörper um eine parallel zur Längsachse des Führungskörpers laufende Achse zulässt.
  7. Vorrichtung gemäß einem der vorherigen Ansprüche, dadurch gekennzeichnet, dass das Führungselement mit dem Schwimmkörper an einer zentralen Position auf einem Arbeitsdeck des Schwimmkörpers verbunden ist.
  8. Vorrichtung gemäß einem der vorherigen Ansprüche, dadurch gekennzeichnet, dass der Stützkörper des Führungselements eine Drehung um zwei Achsen senkrecht zur Längsachse des Führungselements ermöglicht.
  9. Vorrichtung gemäß einem der vorherigen Ansprüche, dadurch gekennzeichnet, dass die Teile zur Verankerung so ausgeführt sind, dass sie das Führungselement um eine Achse senkrecht zur Längsachse des Führungselements drehen.
  10. Vorrichtung gemäß Anspruch 9, dadurch gekennzeichnet, dass die Teile zur Verankerung Zugkabel enthalten, die mit Ankern versehen sind und mit Hilfe von am Schwimmkörper befestigten Winden gespannt werden können, wobei die durch die Zugkabel entstehenden Spannungen nicht durch die Längsachse des Führungskörpers geleitet werden.
  11. Vorrichtung gemäß einem der vorherigen Ansprüche, dadurch gekennzeichnet, dass der Stützkörper eine konische Kontaktfläche mit dem Gewässer- oder Meeresboden hat.
  12. Vorrichtung gemäß einem der vorherigen Ansprüche, dadurch gekennzeichnet, dass der Stützkörper eine kugelförmige Kontaktfläche mit dem Gewässer- oder Meeresboden hat.
  13. Vorrichtung gemäß Anspruch 2 oder 3, dadurch gekennzeichnet, dass das Positioniergestell miteinander in Verbindung stehende Führungsrohre besitzt, die in dem geometrischen Muster für die Gründungspfähle angeordnet sind.
  14. Vorrichtung gemäß Anspruch 13, dadurch gekennzeichnet, dass die Längsachse des Führungselements im Wesentlichen parallel zur Mittelachse der Führungsrohre verläuft.
  15. Vorrichtung gemäß Anspruch 13 oder 14, dadurch gekennzeichnet, dass die Führungsrohre in einer Länge ausgeführt sind, dass sie bei den Arbeiten über die Wasseroberfläche hinausragen.
  16. Vorrichtung gemäß einem der Ansprüche 13 bis 15, dadurch gekennzeichnet, dass die Führungsrohre schalldämpfend sind.
  17. Verfahren zur Anordnung von Gründungspfählen in einem geometrischen Muster auf einem Gewässer- oder Meeresboden, bestehend aus folgenden Schritten:
    - Lieferung einer Vorrichtung gemäß einem der vorherigen Ansprüche.
    - Arretierung des Schwimmkörpers am Gewässer- oder Meeresboden mit Hilfe der Verankerungsteile.
    - Absenkung eines mit dem Führungselement verbundenen Positioniergestells in Richtung der am Gewässer- oder Meeresboden liegenden Arbeitsposition, dadurch gekennzeichnet, dass der Stützkörper die Unterseite des Führungselements auf dem Gewässer- oder Meeresboden fixiert.
    - Einführen der Pfähle in den Gewässer- oder Meeresboden durch die Führungsrohre des Positioniergestells in der Arbeitsposition.
