Abstract

The device has a metal cross structure (1) formed by metal branches that are reinforced on a side opposed to natural ground (4) by a pyramidal metal structure (2). An internal surface of the cross structure is covered by a metal net (5) that is powered by a periphery cable. The cable is maintained in periphery of the cross structure by metal guides (6). The cross structure is fixed at the natural ground by an anchoring bar (3) and terminated in its end by a retaining nut (7) that is supported on a metal pyramidal reinforcement point of the pyramidal metal structure.

Description

La présente invention concerne un système de retenue collinaire et de confortement de sol utilisant un filet métallique mis en tension par une croix métallique renforcée, positionné et fixée au sol par une barre d'ancrage. Elle permet de conforter et de stabiliser des terrains. Elle permet de bloquer et de drainer les matériaux qu'elle maintient. L'absence de cet écran ne permet pas une intervention rapide dans des zones difficiles d'accès pour stopper un glissement de terrain. L'absence de cet écran ne permet pas le confortement du sol dans des zones de forte pente où la construction d'un mur poids traditionnel 1 o accentuerait la surcharge du terrain et favoriserait son glissement L'absence de cet écran ne permet pas de drainer la totalité de l'eau stagnante ou circulante en amont de l'ouvrage, ne supprimant pas la poussée et la surcharge provoquée par la présence de cette eau. L'absence de cet écran ne permet pas la mise en place d'un dispositif 15 de retenue collinaire sans travaux de terrassement préliminaire. L'absence de l'écran ne permet pas de réaliser un compactage optimum des matériaux L'écran selon l'invention permet de remédier à ces inconvénients. Elle permet de mettre en oeuvre rapidement dans des zones escarpées et d'accès 20 difficiles un système léger ne nécessitant pas d'emprise importante dans le terrain naturel. L'écran permet par sa légèreté et l'absence de renforts côté terrain naturel de faciliter sa pose sans modifier le profil du terrain naturel et ainsi de ne pas le déstabiliser. 25 L'écran sur toute sa surface permet de filtrer l'eau et ainsi d'assécher les matériaux se trouvant à l'amont. L'écran étant fixé au sol par un mono ancrage rend sa pose très rapide, et permet de bloquer rapidement un glissement de terrain. The present invention relates to a system for retaining soil and reinforcing soil using a metal net tensioned by a reinforced metal cross, positioned and fixed to the ground by an anchor bar. It helps to consolidate and stabilize land. It allows to block and drain the materials it maintains. The absence of this screen does not allow a quick intervention in areas difficult to access to stop a landslide. The absence of this screen does not allow the comfort of the ground in areas of steep slope where the construction of a wall weight traditional 1 o would accentuate the overload of the ground and promote its sliding The absence of this screen does not allow to drain all the stagnant or circulating water upstream of the structure, not suppressing the thrust and overload caused by the presence of this water. The absence of this screen does not allow the installation of a hill retaining device 15 without preliminary earthworks. The absence of the screen does not allow for optimum compaction of materials The screen according to the invention overcomes these disadvantages. It makes it possible to implement quickly in difficult steep and difficult areas a light system that does not require a large footprint in the natural terrain. The screen allows its lightness and lack of reinforcements on the natural terrain to facilitate its installation without changing the profile of the natural terrain and thus not to destabilize. The screen over its entire surface makes it possible to filter the water and thus to dry up the materials located upstream. The screen is attached to the ground by a single anchor makes its installation very fast, and can quickly block a landslide.

Et 3000mm de largeur. The accompanying drawings illustrate the invention: FIG. 1 represents in section, the device of the invention, FIG. 2 represents the perspective of the device of the invention, FIG. 3 represents the typical detail of one end of the view. In reference to these drawings, the device has an average useful height of 2500 mm. And 3000mm wide.

L'écran est constitué par une croix (1) métallique renforcée par une structure métallique pyramidale (2) de même nature. Le centre de la croix et du renfort sont percés d'un trou permettant le passage de la barre d'ancrage (3), qui fixera l'écran au terrain naturel (4). The screen is constituted by a cross (1) metal reinforced by a pyramidal metal structure (2) of the same nature. The center of the cross and the reinforcement are pierced with a hole allowing the passage of the anchor bar (3), which will fix the screen to the natural ground (4).

La surface interne (côté terrain) de la croix métallique sera recouverte par un filet métallique (5) mis en tension par son câble métallique de pourtour (8) et fixé aux extrémités des quatre bras formant la croix par des guides métalliques (6). Une extrémité de la barre d'ancrage sera scellée au terrain naturel (4) La deuxième extrémité sera équipée d'un écrou de serrage (7) qui viendra prendre appui sur la pointe du renfort pyramidal. 10 The inner surface (ground side) of the metal cross will be covered by a metal net (5) tensioned by its surrounding wire rope (8) and fixed to the ends of the four arms forming the cross by metal guides (6). One end of the anchor bar will be sealed to the natural ground (4) The second end will be equipped with a clamping nut (7) which will bear on the tip of the pyramidal reinforcement. 10
