Abstract
Description
La présente invention concerne un dispositif de lestage et d'accrochage de matériaux : cailloux, terre, sable, ... notamment sur des talus à fortes pentes. Il existe sur le marché différentes méthodes de lestage ou d'accrochage, mais elles sont limitées à des talus peu pentus et le maintien des matériaux est aléatoire. The present invention relates to a device for ballasting and attachment of materials: pebbles, earth, sand, ... especially on slopes with steep slopes. There are different weighting or fastening methods on the market, but they are limited to sloping slopes and the maintenance of materials is random.
Le dispositif selon l'invention permet de palier à ces inconvénients. Il est constitué en effet d'une Géogrille, qui est enroulée et maintenue fermée à l'aide de liens, permettant de réaliser des compartiments de longueurs et sections à la demande, dans le but de confiner des matériaux. Les dessins annexés illustrent l'invention : La figure 1 représente une vue de la Géogrille, à plat, telle que utilisée actuellement pour le renforcement de sol. La figure 2 représente la géogrille enroulée et maintenue par un collier formant un compartimentage. La figure 3 représente des sacs ou boudins, contenant des matériaux, qui ont été 15 placés à l'intérieur des compartiments. Les compartiments peuvent accueillir soit des sacs remplis de matériaux, soit des sacs ou des gaines à remplir de ces mêmes matériaux. Les gaines pourront être étanches ou réalisées à l'aide d'un synthétique drainant, en fonction notamment des matériaux qu'elles devront contenir. Le compartimentage permet de remplacer 20 facilement un sac défectueux, sans manipuler ceux qui l'entourent. Le compartimentage étant réalisé avec la Géogrille, c'est cette dernière qui reprendra tous les efforts, sans que les sacs ou les gaines soient sollicités. Les sacs auront ainsi une durée de vie beaucoup plus longue que lorsqu'ils sont attachés les uns aux autres au moyen de corde par exemple. 25 La résistance de la Géogrille sera calculée en fonction des efforts qu'elle devra reprendre. Sur le marché, elles sont proposées pour des résistances de 20 à 200kN/m et plus. Elles sont utilisées à plat pour le renforcement de sol. A titre d'exemple non limitatif, le dispositif selon l'invention peut couvrir des talus de plusieurs dizaines de mètres de longueur. Dans certains cas, il pourra même 30 être posé verticalement. The device according to the invention overcomes these disadvantages. It consists of a geogrid, which is rolled up and held closed by means of links, making it possible to make compartments of lengths and sections on demand, in order to confine materials. The accompanying drawings illustrate the invention: Figure 1 shows a view of the Geogrid, flat, as currently used for soil reinforcement. Figure 2 shows the geogrid wound and held by a collar forming a subdivision. Fig. 3 shows bags or rolls containing materials which have been placed inside the compartments. The compartments can accommodate either bags filled with materials or bags or sheaths to be filled with these same materials. The sheaths may be waterproof or made using a draining synthetic, depending in particular materials they must contain. Compartmentalization makes it easy to replace a defective bag without handling those around it. The subdivision being realized with Geogrid, it is this one that will take all the efforts, without the bags or the sheaths being solicited. The bags will have a much longer life than when they are attached to each other by means of rope for example. The resistance of the Geogrid will be calculated according to the efforts it will have to take. On the market, they are proposed for resistances of 20 to 200kN / m and more. They are used flat for soil strengthening. By way of non-limiting example, the device according to the invention can cover slopes of several tens of meters in length. In some cases, it may even be placed vertically.
