Abstract

The device has a central pointed tube (2) welded at the center of a cover (5) onto which a metal ring (6) is welded. The cover comprises an orifice i.e. opening (8), equipped with a valve. The metal ring on the cover allows compressing the material under the ring when the cover descends under the action of depression. The opening in the cover allows creating depression or pressure inside a tube (3) by the tube based on the needs.

Description

-1- La présente invention concerne un dispositif permettant de créer une fixation très solide sur tout sols tendres et particulièrement sur tout sols sous marin. Le dispositif selon l'invention permet d'obtenir des fixations très solides facile à réaliser et facile à démonter, ce qui n'est pas le cas des types de fixation utilisés habituellement. The present invention relates to a device for creating a very strong attachment to any soft soil and particularly on any underwater soil. The device according to the invention makes it possible to obtain very strong fastenings which are easy to produce and easy to disassemble, which is not the case with the types of fastener conventionally used.

Il comporte selon une première caractéristique un tube central pointu équipé d'une cloche sur laquelle est soudée un anneau métallique. Cette cloche est pourvue d'un orifice par lequel l'air ou l'eau qu'elle contient peuvent être aspirés. Dés que la cloche entre en contact avec le sol marin on peut créer une dépression à l'intérieur en aspirant l'eau qu'elle contient et lui permettre de s'enfoncer avec facilité. En s'enfonçant dans le sol marin le tube pointu comprime la matière sur la partie interne de la cloche et l'anneau métallique comprime la matière sur la partie extérieure de la cloche assurant ainsi une fixation solide. En maintenant la dépression dans la cloche on permet à la pression de l'eau d'exercer une pression sur celle-ci qui augmente la solidité de la fixation de la cloche sur le sol marin. Pour désolidariser la cloche du sol marin il suffit de créer une pression dans celle-ci. Le dispositif peut être suspendu par un câble et être ainsi déposer sur le sol marin à toute profondeur 15 La fixation peut être réalisée à distance. Selon des modes particuliers de réalisation : -le tube pointu peut être fixé au centre de la cloche par soudure , de même, l'anneau métallique peut être soudé sur la cloche -une valve peut être positionnée dans l'orifice situé au sommet de celle-ci afin de pouvoir raccorder un 20 tuyau - le tube central assure une base solide pour toute fixations. Un dessin illustre le dispositif En référence à ce dessin, le dispositif comporte un tube central pointu (2) soudé au centre d'une cloche (5) sur laquelle est soudé un anneau (6). Cette cloche comporte un orifice (8) équipé d'une valve qui permet 25 le raccordement d'un tuyau (3) pour pouvoir créer une dépression ou une pression dans la cloche (5) ayant pour effet de solidariser ou désolidariser le dispositif par rapport au sol marin. Le dispositif selon l'invention peut permettre de créer très facilement et à moindre coût des fixations sous marine très solides et démontable très facilement. It comprises according to a first characteristic a pointed central tube equipped with a bell on which is welded a metal ring. This bell is provided with an orifice through which the air or the water which it contains can be sucked up. As soon as the bell comes into contact with the sea floor, it is possible to create a depression inside by sucking up the water it contains and allowing it to sink easily. By sinking into the sea floor the pointed tube compresses the material on the inner part of the bell and the metal ring compresses the material on the outer part of the bell thus ensuring a solid fixation. By maintaining the depression in the bell the pressure of the water is allowed to exert a pressure on it which increases the strength of the fixation of the bell on the sea floor. To separate the bell from the sea floor just create a pressure in it. The device can be suspended by a cable and thus be deposited on the seabed at any depth. The attachment can be carried out remotely. According to particular embodiments: -the pointed tube can be fixed to the center of the bell by welding, likewise, the metal ring can be welded to the bell -a valve can be positioned in the hole at the top of that in order to connect a pipe - the center tube provides a solid base for any fasteners. A drawing illustrates the device With reference to this drawing, the device comprises a pointed central tube (2) welded to the center of a bell (5) on which is welded a ring (6). This bell has an orifice (8) equipped with a valve which allows the connection of a pipe (3) to be able to create a depression or a pressure in the bell (5) having the effect of securing or disengaging the device relative to on the sea floor. The device according to the invention can make it very easy and inexpensive to create underwater fasteners very strong and easily removable.

Claims

CLAIMS1) Device for creating a very strong fixation on any soft ground and particularly on all underwater soil. Characterized in that it comprises a pointed tube (2) welded in the center of a bell (5) on which is welded a ring (6). This bell has an orifice (8) equipped with a valve.

2) Device according to claim 1 characterized in that the pointed tube (2) is welded to the center of a bell (5) which can be inserted into the soft ground (1) or be extracted easily under the action of a depression or pressure.

3) Device according to claim 1 characterized in that the positioning of the bell (5) on the pointed tube (2) allows, when the bell (5) goes down, to the soil material (1) located under the bell ( 5) to be pressed against its inner wall.

4) Device according to claim 1 characterized in that the positioning of the metal ring (6) on the bell (5) allows, when the bell descends under the action of depression, to compress the material under this ring (6). )

5) Device according to claims 3 and 4 characterized in that the increase of 15 pressures on each side of the bell (5) allows the device to ensure a solid attachment.

6) Device according to claim 1 characterized in that the orifice (8) in the bell (5) allows, through a pipe (3) to create desired depression or pressure inside of it.
