Abstract

The support consists of a stake (2) made from food-grade plastic, with a small-mesh sleeve (7) covering at least the part of the stake located below water level. The sleeve is also of food-grade plastic, produced by extrusion and has a square mesh of 1.5 - 2.5 mm per side, the sides of the squares being set at 45 degrees to the axis (10) of the stake, which is preferably hollow with holes (8) through its smooth walls. The stake has one end shaped to form a cruciform tip (4).

Description

L'invention concerne le domaine de la mytiliculture. The invention relates to the field of mussel farming.

Dans une moulière, les moules s'accrochent en grappes des pieux plantés dans le fond de la moulière et espacés de 0,5m 1,5m. Ces pieux sont habituellement réalisés à partir de troncs de pins et ont une longueur de 4 à 7m et un diamètre voisin de 160mm. pieux sont plantés dans la vase sur une profondeur de 1 à 3m et la partie supérieure de pieux trempe dans l'eau de la moulière. In a mussel, the mussels hang in clusters of stakes planted in the bottom of the mussel and spaced 0.5m 1.5m. These piles are usually made from pine trunks and have a length of 4 to 7m and a diameter close to 160mm. piles are planted in the mud to a depth of 1 to 3m and the upper part of piles soaks in the water of the mussel.

De maniere naturelle, les naissains s'accrochent sur la partie supérieure immergée de ces pieux en bois du fait que ces derniers présentent sur leur surface des aspérités propices à l'accrochage des naissains. In a natural way, the spat hang on the submerged upper part of these wooden stakes because they present on their surface roughness conducive to the hanging of the spat.

Les pieux en bois ont une durée de vie relativement courte et lorsqu'ils sont abîmés, il est nécessaire de les remplacer par de nouveaux pieux. Ces opérations de rénovation des moulières sont coûteuses et éprouvantes pour le personnel. Wooden piles have a relatively short lifespan and when they are damaged, it is necessary to replace them with new piles. These renovation operations of the molds are costly and difficult for the staff.

Les essais effectués jusqu'à présent pour remplacer les pieux traditionnels en bois de pin par des supports réalisés en autre matériau, tels que des pieux en matière plastique, n'ont donné satisfaction, les moules ne s'accrochent pas sur ces supports quel que soit le profil que l'on donne à leur surface extérieure. The tests carried out until now to replace the traditional piles out of pine wood by supports carried out in other material, such as piles out of plastic material, did not give satisfaction, the molds do not hang on these supports whatever or the profile that we give to their exterior surface.

Le but l'invention est de proposer un nouveau support pour moulière qui soit peu coûteux et facile à mettre en oeuvre, qui une durée de vie supérieure à celle des pieux en bois actuels et qui donne satisfaction en ce qui concerne l'accrochage des moules. The object of the invention is to provide a new support for a mold which is inexpensive and easy to implement, which has a longer life than that of current wooden piles and which is satisfactory with regard to the attachment of the molds. .

L'invention concerne donc un support utilisé en mytiliculture pour l'accrochage des moules. The invention therefore relates to a support used in mussel culture for hanging mussels.

Selon l'invention ce support est caractérisé par le fait qu'il comporte un pieu réalisé en un matériau plastique et gaine réticulée à mailles étroites enveloppant au moins la partie pieu destinée à être immergée dans l'eau de la moulière. According to the invention, this support is characterized in that it comprises a pile made of a plastic material and cross-linked sheath with narrow meshes enveloping at least the pile part intended to be immersed in the water of the mold house.

Le maillage étroit de la gaine est favorable à l'accrochage des naissains sur cette gaine, et les pieux servent fonctionnellement de support de gaine. The narrow mesh of the sheath is favorable to the hanging of spat on this sheath, and the posts function functionally as a sheath support.

De préférence cette gaine est réalisée en un matériau plastique. Le matériau plastique constitutif de la gaine et du pieu est type alimentaire. Il est choisi parmi les polyoléfines. La gaine est avantageusement réalisée par extrusion. Elle comporte des mailles quadrangulaires de 1,5 à 2,5mm de côté. Les dimensions internes de la gaine sont adaptées aux dimensions externes du pieu et ce dernier présente avantageusement sous la forme d'une tube à parois lisses. tube peut comporter des orifices latéraux pour mettre en communication l'intérieur du tube et l'extérieur. Preferably this sheath is made of a plastic material. The plastic material constituting the sheath and the pile is food type. It is chosen from polyolefins. The sheath is advantageously produced by extrusion. It has quadrangular meshes of 1.5 to 2.5mm side. The internal dimensions of the sheath are adapted to the external dimensions of the pile and the latter advantageously has the form of a tube with smooth walls. tube may have lateral openings for communicating the interior of the tube and the exterior.

D'autres avantages et caractéristiques de l'invention ressortiront à la lecture de la description suivante faite à titre d'exemple en référence aux dessins annexés dans lesquels la figure 1 montre en coupe un support selon l'invention plantée dans une moulière ; et la figure 2 montre à plus grande échelle une partie de gaine. Other advantages and characteristics of the invention will emerge on reading the following description given by way of example with reference to the appended drawings in which FIG. 1 shows in section a support according to the invention planted in a mold; and Figure 2 shows on a larger scale a part of the sheath.

Le dessin montre un support 1 destiné à l'accrochage de moules d'élevage dans une moulière 6 qui comporte essentiellement tube creux 2 équipé à son extrémité inférieure 3 d'une pointe 4 facilitant l'enfoncement du support dans la vase 5 qui repose dans le fond de la moulière 6, et dont la partie supérieure immergée dans l'eau de la moulière 6 est enveloppée dans une gaine réticulée 7. The drawing shows a support 1 intended for the attachment of breeding molds to a mold 6 which essentially comprises hollow tube 2 equipped at its lower end 3 with a tip 4 facilitating the insertion of the support into the vase 5 which rests in the bottom of the mold 6, and the upper part of which is immersed in the water of the mold 6 is wrapped in a reticulated sheath 7.

Le tube 2, et la gaine 7 sont réalisés en un matériau plastique, de type alimentaire, de préférence choisi parmi les polyoléfines. Par type alimentaire, on entend dans le présent mémoire que le matériau est inoffensif pour la santé des moules et pour la santé des consommateurs de moules. The tube 2 and the sheath 7 are made of a plastic material, of the food type, preferably chosen from polyolefins. By food type is meant in the present specification that the material is harmless for the health of the mussels and for the health of consumers of mussels.

Pour éviter que l'air reste emprisonné à l'intérieur du tube 2, il est prévu quelques orifices 8, à travers la paroi de ce tube 2 qui permettent à l'eau de la moulière de pénétrer à l'intérieur du tube 2. To avoid that the air remains trapped inside the tube 2, some orifices 8 are provided, through the wall of this tube 2 which allow the water from the mold house to penetrate inside the tube 2.

Comme on le voit sur la figure 2, la gaine réticulée 7 comporte des mailles 9 carrées ou sensiblement carrées dont les dimensions sont comprises entre 1,5 et 2,5mm. Les côtés des mailles 9 font de préférence un angle de 45 avec l'axe 10 du tube 2. As can be seen in FIG. 2, the reticulated sheath 7 comprises square or substantially square meshes 9 whose dimensions are between 1.5 and 2.5 mm. The sides of the meshes 9 preferably make an angle of 45 with the axis 10 of the tube 2.

La section de la gaine réticulée 7 est adaptée à la section du tube 2. Ce dernier a, par exemple, un diamètre compris entre 10 et 20cm et ses parois sont lisses. The section of the reticulated sheath 7 is adapted to the section of the tube 2. The latter has, for example, a diameter of between 10 and 20 cm and its walls are smooth.

La gaine 7 peut évidemment envelopper le tube 2 sur toute sa longueur. Elle doit normalement tenir seule sur le tube 2. Mais on peut également réaliser quelques points de soudure par fusion ponctuelle du matériau constitutif de la gaine 7, lorsque le tube 2 est enfilé dans la gaine 7. The sheath 7 can obviously wrap the tube 2 over its entire length. It should normally stand alone on the tube 2. However, it is also possible to produce a few weld points by punctual melting of the material constituting the sheath 7, when the tube 2 is threaded into the sheath 7.

Le tube 2 est réalisé de préférence par extrusion en continu et découpé à la longueur souhaitée. Afin d'augmenter sa rigidité, des cloisons radiales, se recoupant le long de l'axe 10 du tube 2 et rejoignant sa paroi périphérique, sont avantageusement prévues à l'intérieur du tube 2. L'intérieur du tube 2 est alors séparé en plusieurs chambres longitudinales. Dans ce cas, les orifices 8 sont répartis de telle manière que chaque chambre puisse recevoir l'eau de la moulière. Après la découpe du tube 2 à la bonne longueur, l'une de ses extrémités est taillée afin de former une pointe 4 cruciforme. The tube 2 is preferably produced by continuous extrusion and cut to the desired length. In order to increase its rigidity, radial partitions, overlapping along the axis 10 of the tube 2 and joining its peripheral wall, are advantageously provided inside the tube 2. The interior of the tube 2 is then separated into several longitudinal chambers. In this case, the orifices 8 are distributed in such a way that each chamber can receive the water from the mold. After cutting the tube 2 to the correct length, one of its ends is cut to form a cruciform point 4.
