Description

Unterwasser-Fundament-Baggerungen oder Ausschachtungen, insbesondere für Windkraft- oder Strömungs-Anlagen werden üblicherweise mit auf Pontons stehenden Bohranlagen, Seilbaggern, Hydraulikbaggern oder Saugbaggern ausgeführt. Spätestens bei größeren Wassertiefen und im Offshore-Bereich stoßen diese Verfahren an ihre Grenzen.Underwater foundation dredging or excavations, especially for wind power or flow systems become common with pontoons, dredgers, hydraulic excavators or dredgers executed. No later than at greater water depths and offshore these methods to their limits.

Die Erfindung ist eine Maschine, welche die Ausschachtung von submarinen Fundamentschächten auch in großen Wassertiefen und rauer Witterung ermöglicht. Die Maschine besteht aus einem tauchfähigen, hohlzylinderartigen Stahlponton, auf welches eine dreidimensional verfahrbare Baggereinrichtung aufgesetzt ist. Selbige kann im Innenbereich des Pontons das unterhalb befindliche Bodenmaterial auf eine zuvor bestimmte Tiefe ausheben, abfordern, außerhalb des Pontons ablagern und gleichzeitig zur Sicherung des entstandenen Schachts einen Schalungsring einlegen. Der Schalungsring dient ferner der Verankerung von Montageseilen und als Kolkschutz.The Invention is a machine, which is the excavation of submarine foundation pits also in big ones Water depths and harsh weather conditions. The machine exists from a submersible, hollow cylindrical steel pontoon on which a three-dimensional movable excavator device is placed. The same can be indoors of the pontoon, the soil material below on a previously dig out certain depth, demand to deposit outside the pontoon and at the same time to secure the resulting shaft a formwork ring Insert. The formwork ring also serves to anchor mounting parts and as a scour seal.

Die Maschine wird über Flutung oder Entleerung des Pontons höhengesteuert, was durch Druckluft bewirkt wird, während die seitliche Positionierung über mehrere, am Pontonumfang eingebaute Wasserstrahldüsen erfolgt. Der eigentliche Baggerbetrieb erfolgt nach dem Lufthebeverfahren oder mittels Baggertauchpumpe. Die Baggeinrichtung ist mit hydraulischen Antrieben versehen, welche von einem Versorgungsschiff aus beliefert und gesteuert werden.The Machine is over Flooding or emptying the pontoon height controlled, resulting in compressed air is effected while the lateral positioning over several, installed at the pontoon circumference water jet nozzles. The actual excavator operation is carried out according to the air lifting method or by dredging pump. The bagging device is hydraulic Drives provided, which supplies from a supply ship and controlled.

Die Maschine arbeitet präzise, schnell, bodenschonend, erschütterungsfrei und lärmlos. Sie eignet sich sowohl für die Gründung tiefer als auch flacher Schwerlast-Fundamente und anderer submarinen Bauwerken und Installationen.The Machine works precisely, fast, soil friendly, vibration free and noiseless. It is suitable for both the foundation deeper as well as flat heavy duty foundations and other submarines Buildings and installations.

Ein Ausführungsbeispiel nach der Erfindung ist in der Zeichnung (1) dargestellt und wird im folgenden näher beschrieben:An embodiment according to the invention is in the drawing ( 1 ) and is described in more detail below:
