Description

Die Erfindung bezieht sich auf ein Verfahren zum Verlegen von Kabeln in flachen Gewässern von einem Fahrzeug aus. Es ist bereits bekannt, zur Herstellung der erforderlichen Kabelrinne Druckwasser zu.be-• nutzen, das aus Düsen in der Fahrtrichtung austritt. Weitere Spülverfahren benutzen an Stelle des Druckwassers Preßluft oder Preßluft und Druickwasser kombiniert. WeiterhinThe invention relates to a method for laying cables in flat Waters from a vehicle. It is already known to produce the necessary Cable tray to.be- • use pressurized water from nozzles in the direction of travel exit. Other flushing methods use compressed air or compressed air instead of pressurized water and pressurized water combined. Farther

»o ist es bekannt, für festere Bodenarten bei gleichzeitiger Verwendung dieser Spülverfahren eine Sägevorrichtung zum Auflockern des Bodens und zum Lösen von im Untergrund etwa befindlichen- festen Körpern zu»O it is known to contribute to firmer soil types simultaneous use of this flushing method a sawing device for loosening up of the soil and for loosening any solid bodies located in the subsurface

'5 verwenden. Die Sägevorrichtung besteht aus zu zwei Gruppen zusammengefaßten Sägeblättern, 'die gegeneinander arbeiten.'Use 5. The sawing device consists of saw blades combined into two groups, 'who work against each other.

Demgegenüber besteht das erfindungsgemäße Spülverfahren darin, daß das PreßgasIn contrast, the flushing method according to the invention consists in that the compressed gas

so und Druckwasser zwei oder mehreren Strahldüsenreihen wechselweise derart zugeführt wird, daß in jeder Austrittsdüse das Druickwasser stoßweise vom Preßgas und umgekehrt unterbrochen wird. Durch diese wechselnde Unterbrechung von Luft und Wasser und die dadurch vorhandene Expansion der Luft entsteht ein stark wechselnder Strömungsdruck, der sog. Wasserschlag, wodurch die Düsen in Schwingungen versetzt werden und so gemeinsam mit dem Wasserstrahl, ähnlich wie der Meißel 'eines Luftdruckhammers, arbeiten. Eine weitere Wirkungserhöhung erfolgt dadurch, daß die Strahldüsenreihen durch Bewegung in der Längsrichtung des Arbeitsauslegers wie eine Säge arbeiten. Dies ist von großem Vorteil,· wenn eine Rinne in gewachsenem Mergel-, Ton-, Kreide- oder Kiesboden gespült werden soll. Bei solchen ' Bodenverhältnissen spülen feststehende Düsen meist anstatt der gewünschten Rinne nur ein Loch in der Strahl- und Arbeitsrichtung in den Boden.so and pressurized water two or more rows of jet nozzles is alternately supplied in such a way that the pressurized water in each outlet nozzle intermittently from the pressurized gas and vice versa is interrupted. Through this alternating interruption of air and water and the resulting expansion of the air creates a strongly changing flow pressure, the so-called water hammer, causing the nozzles to vibrate and so together with the water jet, like the chisel of a pneumatic hammer, work. A further increase in effectiveness takes place in that the jet nozzle rows by movement in the Work the length of the working boom like a saw. This is of great advantage, if a gutter is flushed in natural marl, clay, chalk or gravel soil target. In such 'ground conditions, fixed nozzles usually flush instead of the desired gutter only one hole in the jet and working direction in the ground.

Neben den Strahldüsenreihen angebrachte Sägen, die ebenfalls in der Längsrichtung des Arbeitsauslegers bewegbar sind, unterstützen das Auflockern des Bodens, besonders des gewachsenen festen Bodens.There are saws next to the rows of jet nozzles, which also run lengthways of the working boom are movable, support the loosening of the soil, especially of the solid ground that has grown.

Die auf und ab bewegten Teile sind durch Federn, Ketten o. dgl. gleitlagerfrei geführt. Durch die Vermeidung irgendwelcher Führungen ist die Gefahr vermieden, daß die auf und ab bewegten Teile, wie Sägen und Düsen, •sich durch hohen Druck oder durch den Einfluß von gelöstem' Sand enthaltendem Wasser in Führungen festfressen können.The parts moving up and down are guided by springs, chains or the like without sliding bearings. By avoiding any guides, the risk of the on is avoided and from moving parts, such as saws and nozzles, • through high pressure or through the Influence of dissolved water containing sand can seize up in ducts.
