Die Erfindung betrifft ein Verfahren und ein System zum Herstellen einer Gründung für ein Bauwerk im Wasser.The invention relates to a method and a system for producing a foundation for a structure in the water.
Ein solches Verfahren und ein solches System sind aus der
Eine praktische Anwendung des zuvor beschriebenen Verfahrens bzw. Systems ist offenbart auf S. 139 bis 149 der Mitteilungen des Institutes und der Versuchsanstalt für Geotechnik der technischen Universität Darmstadt, Heft Nr. 91, 2012.A practical application of the above-described method or system is disclosed on pages 139 to 149 of the Communications of the Institute and the Research Institute for Geotechnical Engineering of the Technical University Darmstadt, Issue No. 91, 2012.
Um die zuvor beschriebenen Verfahren bzw. Vorrichtungen einsetzen zu können, muss an der Gründungsstelle ein Versorgungsschiff über den gesamten Zeitraum des Erstellens der Gründung vorhanden sein, dessen Einsatz teuer ist.In order to be able to use the methods or devices described above, a supply ship must be present at the foundation site over the entire period of the creation of the foundation, the use of which is expensive.
Es ist daher Aufgabe der Erfindung, das vorgenannte Verfahren dahingehend zu verbessern, dass es kostengünstiger durchgeführt werden kann.It is therefore an object of the invention to improve the aforementioned method in that it can be carried out more cheaply.
Zur Lösung der erfindungsgemäßen Aufgabe hinsichtlich des Verfahrens sieht die Erfindung ein Verfahren vor, bei dem am Gründungsort eine Führungsvorrichtung auf der Gewässergrundoberfläche abgesetzt wird, ein Casing in der Führungsvorrichtung in Einbringrichtung am Gewässergrund angeordnet wird, im Casing eine Bohrvorrichtung angeordnet wird, im Gewässerboden ein Hohlraum unterhalb des Casings erzeugt wird, indem der Boden mittels der Bohrvorrichtung entfernt wird, das Casing in den Hohlraum abgesenkt wird, bis eine vorgesehene Endtiefe im Boden erreicht wird, die Bohrvorrichtung anschließend aus dem Casing entfernt wird, ein Gründungselement in den Hohlraum im Inneren des Casings eingebracht und abgesenkt wird, und der Zwischenraum zwischen Hohlraumwand und der Außenseite des Gründungselements verfüllt wird, wobei das Casing nach dem Einbringen des Gründungselements aus dem Hohlraum entfernt wird, und wobei die Führungsvorrichtung und das Casing getrennt voneinander entfernbar sind..In order to achieve the object according to the invention with regard to the method, the invention provides a method in which a guide device is placed on the body surface at the place of foundation, a casing is arranged in the guide device in the direction of water body bottom, a drilling device is arranged in the casing, a cavity in the water bottom is produced below the casings, by removing the soil by means of the drilling device, the casing is lowered into the cavity until an intended final depth is reached in the soil, the drilling device is subsequently removed from the casing, a foundation element in the cavity inside the Casings is introduced and lowered, and the gap between the cavity wall and the outside of the foundation element is filled, wherein the casing after the introduction of the foundation element is removed from the cavity, and wherein the guide device and the casing separated from each e are removable ..
Eine Trennung der Führungsvorrichtung von der Plattform hat sich als vorteilhaft erwiesen, da es hierdurch möglich wird, das Verfahren in mehreren Abschnitten durchzuführen. In einem ersten Abschnitt wird daher die Führungsvorrichtung als separate Einheit auf der Gewässergrundoberfläche abgesetzt. In diese Führungsvorrichtung wird dann der rohrförmige Casing eingesetzt, der als eine Art Casing fungiert. In das Casing wird die Bohrvorrichtung eingebracht, die dann anschließend den Boden im Gründungsbereich entnimmt. In den dadurch entstehenden Casing wird gegebenenfalls kontrolliert durch die Führungsvorrichtung das Casing eingebracht. Ist das Casing bis an seine Endtiefe in den Boden eingebracht worden, wird das Bohren beendet, und die Bohrvorrichtung aus dem Casing entfernt. Durch das Vorsehen dieses Casings hat es sich als möglich erwiesen, in einem zweiten Verfahrensschritt dann den Monopile in das Casing einzubringen, das Casing zu entfernen und hinterher den Hohlraum zwischen Hohlraumwand und äußerer Wand des Gründungselements zu verfüllen. Nach dem Aushärten des Füllmaterials und der damit einhergehenden Fixierung des Gründungselements im Boden kann das Führungselement entfernt werden.Separation of the guide device from the platform has been found to be advantageous, as this makes it possible to perform the method in several sections. In a first section, therefore, the guide device is deposited as a separate unit on the water base surface. In this guide device then the tubular casing is used, which acts as a kind of casing. In the casing, the drilling device is introduced, which then subsequently removes the soil in the foundation area. If necessary, the casing is introduced into the resulting casing by the guiding device. Once the casing has been inserted into the ground to its final depth, drilling is stopped and the drilling device removed from the casing. By providing this casing, it has proven possible to then introduce the monopile into the casing in a second method step, to remove the casing and subsequently the cavity between cavity wall and outer wall of the foundation element to fill. After curing of the filling material and the associated fixation of the foundation element in the ground, the guide element can be removed.
Hierdurch ist es auf einfache Weise möglich, das im Stand der Technik beschriebene Verfahren in mehrere Abschnitte aufzuteilen, die kostengünstig von mehreren Einheiten durchgeführt werden können. So ist es möglich in einem Bereich, in dem mehrere Bauwerke errichtet werden sollen, mit einer ersten Einheit erst sämtliche Bohrungen vorzunehmen, um dann anschließend mit einer zweiten Einheit sehr viel schneller die einzelnen Bauwerke errichten zu können.This makes it possible in a simple manner to divide the method described in the prior art into several sections that can be inexpensively performed by multiple units. So it is possible in an area in which several structures are to be built, with a first unit to make all the holes, and then to be able to build a single unit much faster then the individual buildings.
Eine weitere Lehre der Erfindung sieht vor, dass das Führungselement vor oder nach dem Einbringen des Gründungselements in den Casing entfernt wird. Weiterhin ist es vorteilhaft, dass der Casing nach dem Ausbau der Bohrvorrichtung mit einem Verschlusselement verschlossen wird, wobei bevorzugt vor dem Einbringen des Gründungselements das Verschlusselement entfernt wird und/oder es sich bevorzugt bei dem Verschlusselement um einen Deckel handelt. Durch das Verschließen des Casings wird es möglich, insbesondere in Gewässern mit starken Strömungen bzw. hohem Sedimentanteil den Casing zu verschließen, um einen Materialeintrag auf einfache Weise zu verhindern.Another teaching of the invention provides that the guide element is removed before or after the introduction of the foundation element in the casing. Furthermore, it is advantageous that the casing is closed after removal of the drilling device with a closure element, wherein preferably before the introduction of the foundation element, the closure element is removed and / or it is preferably in the closure element is a lid. By closing the casings, it becomes possible to seal the casing, in particular in waters with strong currents or a high proportion of sediment, in order to prevent material entry in a simple manner.
Eine weitere Lehre der Erfindung sieht vor, dass zur Verfüllung des Hohlraums zwischen Hohlraumwand und Gründungselement ein zementhaltiges Material verwendet wird. Hierdurch ist es auf besonders einfache Weise möglich, eine entsprechende Fixierung des Gründungselements im Boden zu erreichen. Weiterhin ist vorteilhaft, dass es sich bei dem Gründungselement um einen Pfahl handelt. Weiterhin ist es vorteilhaft, dass es sich bei dem Bauwerk um eine Windkraftanlage handelt.Another teaching of the invention provides that a cementitious material is used to fill the cavity between the cavity wall and the foundation element. This makes it possible in a particularly simple manner to achieve a corresponding fixation of the foundation element in the ground. Furthermore, it is advantageous that the foundation element is a pile. Furthermore, it is advantageous that the building is a wind turbine.
