Description
BESC HR#IBUNG Kabel- und Rohrverlegung nach der Scbwimmethode. BESC HR # IBUNG Laying cables and pipes using the floating method.
Um Kabel oder Rohre durch Fluß, Watt, Binnensee und Seegebiet zu legen, wurde bisher das Kabel von einem Verlegeschiff direkt mit großem mechanischen Aufwand auf den Gewässerboden gelegt. Eine gewünschte Einspülung konnte nach aufwendigem Verfahren direkt oder später vorgenommen werden. In einem anderen mir bekannten Fall hat man das Kabel an Fässern befestigt und an Ort und Stelle durch Kappen der Halteseile das Kabelstück versenkt.To lay cables or pipes through rivers, mud flats, inland lakes and seas, So far, the cable was directly from a pipe-laying ship with great mechanical effort laid on the bottom of the water. A desired flushing could be done after a lot of work Procedures can be carried out immediately or later. In another I know The case has the cord attached to barrels and in place by capping the Retaining ropes sunk the cable section.
Bei allen Verfahren war es nicht möglich, oder nur mit wirtschaftlich nicht zu vertretendem Aufwand, ein Kabel in sog.With all the procedures it was not possible, or only economically Unreasonable effort, a cable in so-called.
Schlangenlinien zu legen, um Bodenverlagerungen Rechnung zu tragen.Lay serpentine lines to take account of soil displacement.
1.) Dem von mir erdachten Verfahren liegt der Gedanke zugrunde, das Kabel oder Rohr gleich welcher Größe mit dicht an dicht befestigten Schwimmkörperpaaren schwimmfähig zu machen. Ein solches Kabel oder Rohr ist dank seiner Schwimmfähigkeit im Wasser leicht zu handhaben.1.) The method I devised is based on the idea that Cable or pipe of any size with tightly attached pairs of floats to make it buoyant. Such a cable or pipe is thanks to its buoyancy easy to handle in water.
Es kann mit einer normalen Seilwinde, von Hand oder von einem Wasserfahrzeug in die genaue Lage eingeschwommen werden. Durch vorher gesetzte See zeichen oder Bojen kann ein genauer Verlauf fixiert werden. Auch ist es leicht möglich das Kabel so an den Bojen zu befestigen, daß sich eine sog. Schlangenlinie bildet. It can be done with a normal winch, by hand or from a watercraft be swum into the exact position. By previously set sea marks or An exact course can be fixed for buoys. It is also easily possible to use the cable to be attached to the buoys in such a way that a so-called serpentine line is formed.
2.) Die Absenkung erfolgt dann kontinuierlich beispielsweise durch Nadelstiche in einen der beiden Auftriebskörper, die als Paar das Kabel oder Rohr tragen (Zeichng.1).2.) The lowering then takes place continuously, for example through Needle pricks in one of the two floats that pair the cable or tube wear (drawing 1).
Hierdurch kann der Äbsenkungsvorgang praktisch ohne Kraftaufwand beschädigungsfrei ftoi für das Objekt erfolgen und jederzeit gestoppt werden. Durch die Entlüftung eines der Auftriebskörper wird vermieden, daß Plastikteile und Folien bei einem solchen Verlegevorgang die Gewässer verunreinigen Das Verlegen in Schlangenlinie ist besonders im Watt, Flüssen und Seen wünschenswert, wenn eine Selbsteinspülung des Kabels durch Strömung erfolgen soll oder Grundverlagerungen zu befürchten sind. In jedem Fall schließt dieses Verfahren eine nachträgliche Einspülung nach konventioneller Art nicht aus. This means that the lowering process can be carried out with practically no effort damage-free ftoi for the object and can be stopped at any time. By venting one of the floats avoids plastic parts and foils such a laying process pollute the waters. Laying in a serpentine line is particularly desirable in the mudflats, rivers and lakes if a self-flushing is required of the cable is to be caused by the current or fundamental shifts are to be feared. In any case, this procedure includes a subsequent flushing after the conventional one Kind of not out.
Das beschriebene Verfahren wurde am 24. 11. 70 erstmalig bei einer Kabelverlegung durch den alten Ostearm bei Geversdorf erfolgreich durchgeführt. Es konnte, da eine Verlegung in Schlangenlinie erreicht wurde (Zeichng. 2), normales nicht zugfestes Hochspannungskabel der Type NÄEKBA verwendet werden.The procedure described was first carried out on November 24, 1970 at a Cable laying through the old Ostearm near Geversdorf successfully completed. Since laying in a serpentine line was achieved (drawing 2), it could be normal Non-tensile high-voltage cables of type NÄEKBA are used.
Dieses Kabel ist bedeutend preisgünstiger als langsarmiertes Kabel.This cable is significantly cheaper than long armored cable.
Bei möglichen Bodenveränderungen kann sich das Kabel den Unebenheiten anpassen.In the event of possible changes in the ground, the cable can move against the unevenness adjust.
Die Kosten betrugen ca. 10 % des sonst praktizierten Verfahrens. Anfrage seitens des Wasser- und Schiffahrtsamtes liegen vor.The costs amounted to approx. 10% of the otherwise practiced procedure. inquiry on the part of the Waterways and Shipping Office are available.
