2889214 DESCRIPTIF2889214 DESCRIPTION
L'invention est relative aux structures immergeables et concerne plus particulièrement, parce que c'est dans ce cas que son application semble la plus intéressante mais non exclusivement, des structures destinées à la réalisation de récifs artificiels, à l'aménagement de sites aquatiques, à la protection de zones de surface ou de profondeur pouvant servir par exemple de système anti-houle, de brise lames, de structures ludiques, etc... The invention relates to immersible structures and more particularly, because it is in this case that its application seems most interesting but not exclusively, structures for the realization of artificial reefs, the development of aquatic sites, the protection of surface or depth areas that can be used for example anti-wave system, breakwaters, play structures, etc ...
On a proposé, dans l'art antérieur des récifs artificiels constitués par des matériaux lourds tels que le béton présentant différentes formes et alvéoles, des structures assemblées en amas. It has been proposed in the prior art artificial reefs consisting of heavy materials such as concrete with different shapes and cells, structures assembled in clusters.
1 o La conception de ces structures principalement d'origine japonaise et coréennes visent à développer des fonctions d'attraction et d'habitat pour les poissons et crustacés. 1 o The design of these structures mainly of Japanese and Korean origin aims to develop attraction and habitat functions for fish and shellfish.
Des structures plus légères basées sur le déploiement de spirales ont été développées Brevet - D. Bordes Sue 82 143 72, ou à base d'éléments filiformes fixés sur une base servant de lest, Brevet -Bordes-Süe 2 810 684. Des structures concernant des pieux aménagés ont été conçues récemment, brevet Etienne Clamagirand Avril 2000. Lighter structures based on the deployment of spirals have been developed Patent - D. Bordes Sue 82 143 72, or based on filamentary elements fixed on a base serving as ballast, Patent-Bordes-Süe 2 810 684. Structures concerning developed piles were recently designed, Etienne Clamagirand patent April 2000.
Les structures proposées dans le présent brevet visent à développer plus particulièrement des récifs à fonction d'attraction du poisson, à fonction trophique par enrichissement du biotope et à fonction ludique des récifs artificiels. The structures proposed in this patent are intended to develop more particularly reefs with a function of attracting fish, trophic function by enriching the biotope and playful function of artificial reefs.
D'autre part, elles présentent l'intérêt de minimiser le coût de mise à l'eau d'un récif, lequel est fonction du volume et du poids chargé et transporté jusqu'au lieu d' immersion. On the other hand, they have the advantage of minimizing the cost of launching a reef, which is a function of the volume and weight loaded and transported to the place of immersion.
Ces structures récifales immergeables présentent la particularité d'être transportées en Kit, la mise en forme finale s'effectuant sur le lieu d'immersion. En ce qui concerne les fonction ludiques du récif, il paraît important d'aménager des sites sous marins pour la plongée ou la pêche récréative en développant des structures pouvant créer des tunnels, des voûtes, des labyrinthes ou toute autre structure. These immersible reef structures have the particularity of being transported in Kit, the final shaping taking place on the place of immersion. With regard to the recreational functions of the reef, it seems important to develop underwater sites for diving or recreational fishing by developing structures that can create tunnels, vaults, labyrinths or any other structure.
En ce qui concerne la fonction attractive pour le poisson de ce type de récif, la structure filiforme de ses composants traversées par les courants, permet de créer des vibrations dans la masse d'eau qui ont un impact sur la ligne latérale des poissons. With regard to the attractive function for the fish of this type of reef, the filiform structure of its components crossed by the currents, makes it possible to create vibrations in the body of water which have an impact on the lateral line of the fish.
En ce qui concerne la fonction alimentaire du récif qui présente une complémentarité indispensable aux récifs de fonction habitat , nous nous orientons dans l'utilisation de structures comportant des éléments filiformes à surface rugueuse permettant la fixation puis le développement des espèces animales ou végétales ciblées. With regard to the reef food function, which has an essential complementarity to the habitat function reefs, we are focusing on the use of structures with filiform elements with rough surfaces allowing the fixation and development of the targeted animal or plant species.
Le récif à base d'éléments filiformes, par sa capacité à fixer principalement des organismes filtreurs, peut être considéré comme remplissant une fonction de "Restauration" de la qualité de l'eau. The reef based on filiform elements, by its ability to fix mainly filtering organisms, can be considered as fulfilling a function of "restoration" of water quality.
La section des éléments filiformes est indifféremment cylindrique, ovale, carrée ou rectangulaire ou toute forme plus élaborée ( cruciforme, T...). L'exemple type de récifs alimentaires est la corde de culture de moule. La corde de culture de moule se présente soit suspendue, soit enroulée sur bouchot. The section of the filiform elements is indifferently cylindrical, oval, square or rectangular or any more elaborate form (cruciform, T ...). The typical example of food reefs is the mold growing rope. The mold culture rope is either suspended or wrapped on bouchot.
Les structures récifales du présent brevet se composent d'un axe central tubulaire (1), droit ou courbe, positionné de manière oblique ou verticale sur le fond, axe sur lequel sont positionnés des moyens de fixation (2) d'un ou plusieurs éléments filiformes (3) fixés par l'une des extrémités (4) ou par les deux extrémités sur un (5) ou deux (6) moyens de fixation (2). (Figure 1) L'axe central (1) rigide ou semi- rigide, creux ou plein, peut avoir des diamètres et de sections variables, est fabriqué en matériaux tels que béton armé, matériaux composites ou plastiques, métaux et alliages. The reef structures of this patent consist of a tubular central axis (1), straight or curved, positioned obliquely or vertically on the bottom, axis on which are positioned means (2) for fixing one or more elements filiforms (3) fixed by one of the ends (4) or at both ends to one (5) or two (6) fastening means (2). (Figure 1) The central axis (1) rigid or semi-rigid, hollow or solid, can have diameters and variable sections, is made of materials such as reinforced concrete, composite materials or plastics, metals and alloys.
L'axe central peut être fixé sur une base en béton armé ou métallique servant de lest (7) (Figure 1), être enfoncé dans le sol (8) (Figure 2), associer les deux méthodes précédentes (9), (Figure 3), enfin toutes ces méthodes peuvent être haubanées ou stabilisées par des moyens rigides (10) (Figure 4). The central axis can be fixed on a reinforced concrete base or metal ballast (7) (Figure 1), be pressed into the ground (8) (Figure 2), combine the two previous methods (9), (Figure 3), finally all these methods can be braced or stabilized by rigid means (10) (Figure 4).
Les structures réalisées peuvent être composées d'une pluralité d'axes centraux tubulaires reliés entre eux par des éléments filiformes, figure 18. The structures produced may be composed of a plurality of tubular central axes interconnected by filiform elements, FIG. 18.
Les moyens de fixation (2) des éléments filiformes (3) sont en matériaux divers tels que ciments, matériaux composites, matières plastiques, métaux, alliages. Les éléments filiformes sont scellés sur les moyens de fixation (2) dans des orifices (11). The fastening means (2) filiform elements (3) are made of various materials such as cements, composite materials, plastics, metals, alloys. The filiform elements are sealed on the fastening means (2) in orifices (11).
Ces moyens de fixation (2) peuvent être: Soit des éléments annulaires de forme géométriques variées telles que des cônes, sphères, cylindres, liste des formes non exhaustive, Figure 5 (a) coupe verticale dans le sens de l'axe central (1), figure 5 (b) coupe horizontale (x-x') des sphères, Figure 6 (a) coupe verticale dans le sens de l'axe central, coupe horizontale selon y/y', figure 6 - (b), ou toute autre forme géométrique, coulissant le long de l'axe central tubulaire (1), ces éléments annulaires de fixation (2) étant positionnés et fixés sur l'axe central tubulaire (1) par des moyens de blocage (12), Figure 7. These fixing means (2) may be: Either annular elements of various geometrical shape such as cones, spheres, cylinders, non-exhaustive list of shapes, Figure 5 (a) vertical section in the direction of the central axis (1) ), figure 5 (b) horizontal section (x-x ') of the spheres, Figure 6 (a) vertical section in the direction of the central axis, horizontal section along y / y', figure 6 - (b), or any other geometrical shape, sliding along the tubular central axis (1), these annular fixing elements (2) being positioned and fixed on the tubular central axis (1) by locking means (12), FIG. .
Soit des éléments autonomes (13) parallélépipédiques mais non exclusivement, fixés de manière radiale sur l'axe central par collage, boulonnage (14) ou soudure, coupe verticale dans le sens de l'axe central, Figure 8 - (a), coupe selon le plan horizontal w/w', Figure 8 - (b). Either autonomous elements (13) parallelepipedal but not exclusively, fixed radially on the central axis by gluing, bolting (14) or welding, vertical section in the direction of the central axis, Figure 8 - (a), section along the horizontal plane w / w ', Figure 8 - (b).
Dans le cas où les parois ou le corps de l'axe central (1) sont assez épais pour le permettre, les orifices de scellement (11) sont directement pratiqués dans l'axe central. Figure 9. In the case where the walls or the body of the central axis (1) are thick enough to allow it, the sealing holes (11) are directly made in the central axis. Figure 9.
Les éléments filiformes sont soit scellés sur les moyens de fixation (2) dans des orifices (11) aux orientations préalablement établis, avec des mastics époxy ou des ciments spéciaux (15), Figure 10, soit pris en sandwich entre une ou plusieurs pièces boulonnées, telles des plaques (16) , dotées de sillons (17) permettant le positionnement des éléments filiformes (3) dont les orientations de départ sont préalablement établis, figure 11 Les éléments sandwich de fixation peuvent être regroupés afin de former des faisceaux sur des plaques positionnés sur les moyens de fixation (2) généralement mais pas uniquement selon des plans horizontaux (18) ou verticaux (19), en couronnes de tubes de fixation de joncs (20), figure 14. Des moyens de blocage tels des boulons (23), figure 14 servent à fixer les joncs dans les tubes de la couronne (20). The filiform elements are either sealed to the fastening means (2) in orifices (11) at pre-established orientations, with epoxy sealants or special cements (15), FIG. 10, or sandwiched between one or more bolted pieces. , such plates (16), provided with grooves (17) for positioning the filiform elements (3) whose starting orientations are previously established, Figure 11 The sandwich elements can be grouped together to form beams on plates positioned on the fastening means (2) generally but not only in horizontal (18) or vertical (19) planes, in rings of rod fixing tubes (20), Figure 14. Locking means such as bolts (23). ), Figure 14 serve to fix the rods in the tubes of the ring (20).
Les éléments filiformes fixés dans les éléments sandwich peuvent être 1 o enrobés de mastic de protection ou entourés d'une gaine de protection (21) en matériau semi-rigides ou élastiques tels que les caoutchoucs, les matières plastiques ou toute autre matière permettant d'éviter toute usure par frottement et permettant une bonne fixation par compression Figure 12. The filiform elements fixed in the sandwich elements may be 1 o coated with protective mastic or surrounded by a protective sheath (21) of semi-rigid or elastic material such as rubbers, plastics or any other material allowing avoid any frictional wear and allow a good fixation by compression Figure 12.
La longueur des éléments filiformes est variable selon les structures récifales, 15 généralement de un à 6 mètres, longueurs données pour indication et non limitatives. The length of the filiform elements is variable according to the reef structures, generally from 1 to 6 meters, lengths given for indication and not limiting.
Les éléments filiformes (3) sont fabriqués avec des matériaux imputrescibles tels que les matières plastiques armées ou non, les résines epoxy / fibre de verre, les métaux ou alliage. The filiform elements (3) are made of rot-proof materials such as reinforced or unarmoured plastics, epoxy / fiberglass resins, metals or alloys.
Les éléments filiformes peuvent être creux ou plein, de section plus généralement de section cylindrique mais aussi de toute section géométrique telle que ovale, carrée, rectangulaire, en T, U, V, rainurée, liste non limitative. Les structures peuvent combiner des éléments filiformes préformés ou de simples tiges avec des éléments filiformes mis en forme par flexion. The filiform elements may be hollow or solid, more generally cylindrical section section but also any geometric section such as oval, square, rectangular, T, U, V, grooved, non-limiting list. The structures may combine preformed filiform elements or simple rods with filiform elements shaped by bending.
Lorsque la structure finale est autoporteuse, par exemple avec des forme demi-sphériques (coupole), l'axe central peut être utilisé comme élément de construction puis être enlevée pour une meilleure esthétique de la structure finale. Pour assurer une meilleure résistance de la structure récifale, les éléments filiformes peuvent être renforcés ou reliés entre eux par des pièces d'union (22) parallèles ou croisées à plusieurs voies permettant l'union de 2 à plusieurs joncs. Ces moyens d'union peuvent être des emplâtres de mastics armés de fils imputrescibles, ou des pièces plus élaborées enchâssant en sandwich soit deux ou une pluralité de joncs fixés de manière parallèle (figure 15), soit deux ou une pluralité de joncs fixés de manière croisée selon des angles variables, figure 17. When the final structure is self-supporting, for example with half-spherical shapes (dome), the central axis can be used as a construction element and then removed for better aesthetics of the final structure. To ensure a better resistance of the reef structure, the filiform elements may be reinforced or interconnected by means of parallel or cross-linked union pieces (22) allowing the union of two or more rods. These means of union may be plaster plasters armed with rotproof threads, or more elaborate sandwiching pieces either two or a plurality of rods attached in parallel manner (Figure 15), or two or a plurality of rushes fixed in a manner crossed at various angles, Figure 17.
Dans le cas de la fixation de joncs parallèles, les pièces d'union (22) peuvent comporter plusieurs étages (figure 16). In the case of fixing parallel rods, the union pieces (22) may comprise several stages (FIG. 16).
Ces structures sont complémentaire aux structures Habitat traditionnellement utilisées dans la réalisation de récifs artificiels dans de nombreux programmes d'aménagement de fonds sous marins. These structures are complementary to Habitat structures traditionally used in the construction of artificial reefs in many underwater development programs.
Sa vocation ludique est un atout supplémentaire pour l'aménagement de sites préparés pour la plongée qui deviennent des structures d'aménagement retenues notamment dans les programmes européens de type Natura 2000. Its playful vocation is an additional asset for the development of sites prepared for diving which become management structures selected in particular in European Natura 2000 type programs.
