Abstract

The method involves shutting off the receiving ticking bomb space formed by gripping tool. The air is introduced into the space under the displacing water for disarming bombs. The bomb is dismantled in chamber by high pressure water jet device.

Description

Die Erfindung betrifft ein Verfahren zum Bergen und Entschärfen von auf dem Meeresgrund liegenden Bomben mit den Merkmalen des Oberbegriffs des Anspruch 1.The invention relates to a method for recovering and defusing bombs lying on the seabed with the features of the preamble of claim 1.

Das Bergen und Entschärfen von auf dem Meeresgrund liegenden Bomben ist besonders dann problematisch, wenn die jeweilige Bombe ergriffen, nach oberhalb des Wasserspiegels transportiert und sodann dort entschärft wird.The recovery and disarming of lying on the seabed bombs is particularly problematic when the respective bomb is taken, transported to above the water level and then defused there.

Ein Vorschlag mit den eingangs genannten Merkmalen ist aus der US 7,363,844 B2 bekannt. Dabei wird die zu entschärfende Bombe jedoch ergriffen, in ein Behältnis überführt und dann in diesem an die Wasseroberfläche gefördert. Ein solches Vorgehen aber birgt besondere Verfahren.A proposal with the features mentioned is from the US 7,363,844 B2 known. The bomb to be defused is, however, taken, transferred to a container and then transported in this to the water surface. But such a procedure involves special procedures.

Hingewiesen wird weiter auf die US 3,109,369 A , auf die GB 2 382 540 A , die DE 101 57 166 C1 , die DE 695 04 594 T2 , die das sich stellende Problem der Entschärfung von auf dem Meeresgrund liegenden Bomben nicht in zufirden stellender Weise lösenAttention is directed to the US 3,109,369 A , on the GB 2 382 540 A , the DE 101 57 166 C1 , the DE 695 04 594 T2 that are not solving the problem of defusing sea-level bombs

Der Erfindung liegt die Aufgabe zugrunde, die ein Bergen und Entschärfen von auf dem Meeresgrund liegenden Bomben unter Wasser ermöglicht.The invention is based on the object, which allows a recovery and disarming lying on the seabed bombs under water.

Erfindungsgemäß wird diese Aufgabe gelöst durch Ergreifen der zu entschärfenden Bombe durch ein Greifwerkzeug, Abschotten des von dem Greifer gebildeten Raums, Einbringen von Luft in den Raum unter Verdrängen aufgenommenen Wassers und Zerlegen der Bombe mittels einer im Raum angeordneten Hochdruckwasserstrahleinrichtung, wobei die einzelnen Verfahrensschritte von einem Schiff von einem Ponton ferngesteuert und unter Kameraüberwachung erfolgen.According to the invention, this object is achieved by gripping the bomb to be defused by a gripping tool, Abschotten the space formed by the gripper, introducing air into the space under displacement absorbed water and disassembly of the bomb by means disposed in space high-pressure water jet, the individual steps of a process Ship from a pontoon remotely controlled and under camera surveillance.

Bei dem Greiferwerkzeug handelt es sich um einen Bagger-Greiflöffel, der ein Abschotten des von dem Greifwerkzeug gebildeten Raums gegenüber dem umgebenden Wasser ermöglicht.The gripper tool is an excavator grab bucket which allows the space formed by the gripper tool to be sealed off from the surrounding water.

Besonders bevorzugt ist eine Ausbildung, bei der die Hochdruckwasserstrahleinrichtung mit einer Mehrzahl von senkrecht zu der aufgenommenen Bombe voneinander beabstandeten Schneiddüsen versehen ist.Particularly preferred is an embodiment in which the high-pressure water jet device is provided with a plurality of cutting nozzles which are spaced apart from one another perpendicular to the recorded bomb.

Bei einem bevorzugten Ausführungsbeispiel wird nach dem Zerlegen der Bombe durch die Hochdruckwasserstrahleinrichtung austretende Spreng- und/oder Kampfmittel abgeführt. Das Abführen kann dabei durch Aufziehen des Greiferlöffels mit der bewegten Bombe und dem Spreng- oder Kampfmittelschlamm erfolgen. Alternativ erfolgt das Abführen der aus der Bombe ausgetretenen Spreng- oder Kampfmittel, auch ein Abführen der aus der Bombe ausgetretenen Spreng- und/oder Kampfmittel durch Einbringen von Luft in den Raum unter Verdrängen des Schlamms in das umgebende Wasser kommt in Betracht, dabei sollte jedoch vor dem Abführen des Sprengkampfmittels ein diese neutralisierenden (oder bindenden) Stoffs erfolgen.In a preferred embodiment, after disassembly of the bomb by the high-pressure water jet escaping blasting and / or ordnance is discharged. The removal can be done by pulling the gripper spoon with the moving bomb and the explosive or ordnance sludge. Alternatively, the discharge of the bomb or explosive ordnance that has escaped from the bomb, and also a discharge of the explosives and / or weapons discharged from the bomb by introducing air into the space while displacing the sludge into the surrounding water, should be considered prior to discharging the disintegrant, carry out a neutralizing (or binding) substance.

Der Erfindung liegt also der Grundgedanke zugrunde, die ergriffene Bombe unmittelbar nach dem Aufnehmen durch ein Greifwerkzeug in dem durch diesen gebildeten Raum durch Aufschneiden und Abführen des Spreng- und/oder Kampfmittels zu entschärfen. Die Erfindung nutzt dabei den Umstand, dass die geborgene Bombe sich an den tiefsten Ort des Greifwerkzeugs wälzen wird, bei einer Anbringung von – vorzugsweise einer Mehrzahl – Schneiddüsen kann die jeweilige Schneiddüse bestimmt werden, die eingesetzt werden soll.The invention is therefore based on the basic idea to defuse the bomb taken immediately after picking by a gripping tool in the space formed by this by cutting and removing the explosive and / or ordnance. The invention uses the fact that the recovered bomb will roll to the lowest point of the gripping tool, with an attachment of - preferably a plurality - cutting nozzles, the respective cutting nozzle to be used to be determined.

Nach der Erfindung wird also die ergriffene Bombe nicht einem besonderen Gerät, in dem diese entschärft wird, zugeführt, sondern unmittelbar in dem Greifwerkzeug. Dazu ist es erforderlich, den durch das Greifwerkzeug bei Schließen gebildeten Raum gegenüber dem umgebenen Wasser abzudichten, um das Wasser aus dem Raum abzupumpen, um so das Arbeiten des Hochdruckwasserstrahlgerätes zu ermöglichen.According to the invention, therefore, the bomb taken is not a special device in which it is defused, fed, but directly in the gripping tool. For this purpose, it is necessary to seal the space formed by the gripping tool when closing against the surrounding water to pump the water out of the room, so as to allow the work of the high-pressure water jet device.
