Description

La présente invention a pour objet un ouvrage léger de consolidation de terrains.The present invention relates to a light work of land consolidation.

Jusqu'à présent la consolidation des ter­rains est en général effectué à l'aide de gabions, ou de petits murs de béton armé, ou encore de murs pré­fabriqués. Toutes ces réalisations demandent une main d'oeuvre importante à cause des grandes quantités de matériaux et/ou de terre devant être utilisés.Up to now, land consolidation has generally been done using gabions, or small reinforced concrete walls, or even prefabricated walls. All these achievements require a large workforce because of the large quantities of materials and / or soil to be used.

On a maintenant trouvé un système de conso­lidation de terrains du type mur léger, qui est ef­ficace et facile à mettre en oeuvre.We have now found a consolidation system of land type light wall, which is effective and easy to implement.

L'invention concerne donc un ouvrage léger de consolidation de terrains, caractérisé en ce qu'il comprend une semelle de béton sensiblement en forme de U, dans laquelle est inséré au moins un élément paral­lélépipédique en un matériau plastique alvéolaire sous forme d'un bloc, la partie supérieure dudit élément dépassant de la semelle étant recouverte successive­ment par un grillage et d'une mince couche de béton.The invention therefore relates to a lightweight soil consolidation structure, characterized in that it comprises a substantially U-shaped concrete base, into which is inserted at least one parallelepipedal element made of a cellular plastic material in the form of a block. , the upper part of said element projecting from the sole being successively covered by a mesh and a thin layer of concrete.

Le matériau plastique alvéolaire sous forme de bloc peut être notamment du polystyrène expansé ou du polypropylène en nid d'abeille, ou tout autre ma­tériau semblable.The cellular plastic material in the form of a block may in particular be expanded polystyrene or honeycomb polypropylene, or any other similar material.

Selon d'autres caractéristiques :
    - Afin d'assurer un drainage des eaux, le bloc de matériau plastique alvéolaire peut être muni, à sa partie inférieure dépassant de la semelle de bé­ton, de barbacanes.
    - La partie du bloc de matériau plastique alvéolaire insérée entre les deux branches de la se­melle en forme de U peut être cannelée sur ses faces latérales pour offrir une meilleure adhérence au bé­ton.
    - Le bloc de matériau plastique alvéolaire présente un léger angle entre la verticale et le talus (c'est-à-dire le bord du terrain devant être conso­lidé) pour tenir compte de la flexion du matériau au moment du chargement.According to other characteristics:
- In order to ensure water drainage, the block of cellular plastic material may be provided, at its lower part projecting from the concrete footing, with barbacans.
- The part of the block of cellular plastic material inserted between the two branches of the U-shaped sole can be grooved on its lateral faces to offer better adhesion to concrete.
- The block of cellular plastic material has a slight angle between the vertical and the slope (i.e. the edge of the ground to be consolidated) to take into account the bending of the material at the time of loading.

Dans la plupart des cas de figure, on uti­lisera plusieurs blocs de matériau plastique alvéolaire qui devront être liés entre eux.In most cases, several blocks of cellular plastic material will be used which must be linked together.

Cette liaison peut être effectuée à l'aide d'au moins une tige d'acier, notamment torsadée, tra­versant latéralement les blocs et éventuellement plié en bout. Selon une autre variante, les blocs peuvent être liés entre eux par collage.This connection can be made using at least one steel rod, in particular twisted, laterally crossing the blocks and optionally folded at the end. According to another variant, the blocks can be linked together by gluing.

L'ouvrage léger de consolidation de terrains selon l'invention peut être mis en place par exemple de la manière suivante.The light land consolidation structure according to the invention can be installed, for example, in the following manner.

Préliminairement, les blocs de matériau plastique alvéolaire sont découpés aux dimensions dé­sirées et, le cas échéant, leur partie latérale infé­rieure est cannelée par exemple à la scie. Par ail­leurs, le pied du talus devant être consolidé est dégagé. La base de la semelle de béton en forme de U est coulée in situ et les blocs de matériau plastique alvéolaire sont alignés par dessus et liés entre eux au moyen de tiges d'acier ou de colle. Ensuite les deux branches de la semelle de béton en forme de U sont coulées. Lorsque le béton a pris, le terrain est remblayé et la partie supérieure des blocs de matériau plastique alvéolaire dépassant est recouverte succes­sivement d'un grillage et d'une mince couche de béton par projection.Preliminary, the blocks of cellular plastic material are cut to the desired dimensions and, if necessary, their lower lateral part is grooved for example with a saw. Furthermore, the foot of the slope to be consolidated is released. The base of the U-shaped concrete footing is poured in situ and the blocks of cellular plastic material are aligned on top and linked together by means of steel rods or glue. Then the two branches of the U-shaped concrete footing are poured. When the concrete has set, the ground is backfilled and the upper part of the blocks of protruding cellular plastic material is successively covered with a mesh and a thin layer of concrete by spraying.

L'ouvrage léger de consolidation de terrains selon l'invention est particulièrement facile à mettre en oeuvre et offre une grande sécurité à l'utilisa­ tion, par exemple lors de la construction de routes.The light land consolidation structure according to the invention is particularly easy to implement and offers great safety to the user. tion, for example when building roads.

L'ouvrage léger de consolidation de terrains ou mur léger représenté sur la Fig. 1 comprend une semelle de béton 1 sensiblement en forme de U, dans laquelle est inséré un élément parallélépipédique 2 en un matériau plastique alvéolaire sous forme d'un bloc, la partie supérieure dudit élément dépassant de la semelle étant recouverte successivement par un grilla­ge 3 et d'une mince couche de béton 4, par exemple par projection au moyen d'une buse 5. Les dimensions de la semelle de béton 1 peuvent être par exemple : largeur 1,10 m, hauteur 0,55 m, hauteur des branches du U 0,30 m, la longueur étant choisie selon les nécessités de consolidation. Le bloc 2 en matériau plastique alvéo­laire, notamment du polystyrène expansé (par exemple du "Compostyrène") peut avoir comme dimensions par exemple : hauteur 1,20 m, largeur 0,50 m, et les faces latérales de sa partie insérée, sur une profondeur de 0,30 m par exemple, dans la semelle de béton 1,peut être canellée (non représentée) à l'aide d'une scie. La hauteur utile de ce mur selon les dimensions pré­citées est d'environ 0,90 m. La partie inférieure du bloc 2 dépassant de la semelle 1 est munie d'un sys­tème de barbacanes 6 ayant par exemple un diamètre de 5 cm permettant le drainage des eaux. Le bloc 2 pré­sente utilement un léger angle d'environ 2° entre la verticale et le talus pour tenir de la flexion du ma­tériau plastique alvéolaire au moment du chargement.The light land consolidation work or light wall shown in FIG. 1 comprises a concrete footing 1 substantially in the form of a U, in which is inserted a parallelepipedic element 2 made of a cellular plastic material in the form of a block, the upper part of said element protruding from the sole being successively covered by a grid 3 and of a thin layer of concrete 4, for example by spraying by means of a nozzle 5. The dimensions of the concrete footing 1 can be for example: width 1.10 m, height 0.55 m, height of the branches of the U 0.30 m, the length being chosen according to consolidation needs. The block 2 made of cellular plastic material, in particular expanded polystyrene (for example "Compostyrene") may have as dimensions for example: height 1.20 m, width 0.50 m, and the lateral faces of its inserted part, on a depth of 0.30 m for example, in the concrete footing 1, can be fluted (not shown) using a saw. The useful height of this wall according to the above dimensions is approximately 0.90 m. The lower part of the block 2 protruding from the sole 1 is provided with a system of barbican 6 having for example a diameter of 5 cm allowing the drainage of water. The block 2 usefully has a slight angle of about 2 ° between the vertical and the slope to hold the bending of the cellular plastic material at the time of loading.

Les Figs. 2 et 3 représentent un ouvrage léger de consolidation de terrains de dimensions su­périeures à celui de la Fig. 1, dont la semelle de béton 1 a par exemple comme dimensions : largeur 2,20 m, hauteur 1 m, largeur entre les branches du U 1, hauteur des branches 0,75 m, la longueur pouvant être variée à volonté. Plusieurs blocs 2 de matériau plas­tique alvéolaire, notamment de polystyrène, ayant par exemple comme dimensions 2,50 m x 0,50 m x 1,20 sont insérés dans la semelle sur une profondeur de 0,75 m. Les blocs 2 sont liés entre eux au moyen de tiges d'acier 7 torsadées ayant par exemple un diamètre de 8 mm. Le cas échéant ils peuvent être collés. Pour le reste, c'est à dire le grillage 3, la couche mince de béton 4 pulvérisée par une buse 5 et les barbacanes 6, la réalisation peut être identique à celle de l'ou­vrage de la Fig. 1. Dans cet exemple, la hauteur utile du mur est de 2 m.Figs. 2 and 3 represent a light structure for consolidating land of dimensions larger than that of FIG. 1, of which the concrete footing 1 has for example as dimensions: width 2.20 m, height 1 m, width between the branches of the U 1, height of the branches 0.75 m, the length being able to be varied at will.
