Abstract

The gabion (2) has a gridded bottom (4) that extends primarily in a plane, and a set of side faces (6-9) delimiting a container. The gridded bottom is formed of a wire (28) extending in a direction (X) parallel to and intersected with another wire (30). The former wire is spaced from the latter wire in a direction (Y) so as to form a set of carrying lines (32, 34). Each carrying line or two non-carrier lines is located immediately on the right and the left of each carrying line that differ visually from other non-carrier lines of the bottom.

Description

L'invention concerne un gabion.The invention relates to a gabion.

De plus en plus de techniques de construction dans le domaine du génie civil et des travaux publics font utilisation d'unités ou d'éléments individuels de construction. Ces éléments individuels sont utilisés pour former des parois de soutènement, des murs antibruit, des culées et piles de pont, des merlons de protection contre des chutes de pierres, éboulements et glissements de terrain, des clôtures, des aménagements paysagers, des ouvrages de protection dans le domaine militaire ou des ouvrages de renforcement de voies de circulation, berges de canaux, rivières, fleuves et bords de mer et d'autres encore. Ils sont aussi utilisés pour des ouvrages provisoires.More and more construction techniques in the field of civil engineering and public works make use of units or individual building elements. These individual elements are used to form retaining walls, noise barriers, abutments and bridge piers, protection stone from rocks, landslides and landslides, fences, landscaping, protective structures in the military field or roadway reinforcement works, canal banks, rivers, seascapes and others. They are also used for temporary works.

D'une manière générale, ces éléments individuels sont réalisés à partir de structure de cage renfermant un matériau de remplissage et connus sous l'appellation générale de gabion. Les dimensions de ces gabions peuvent être très variables en fonction de la taille de l'ouvrage et de l'application. Ces gabions sont remplis avec des matériaux, tels que des pierres, des granulats, des galets, du sable, de la terre, du bois, des matériaux à propriétés élastoplastiques telles que des pneus ou d'autres encore.In general, these individual elements are made from cage structure containing a filler material and known under the general name of gabion. The dimensions of these gabions can be very variable depending on the size of the structure and the application. These gabions are filled with materials, such as stones, aggregates, pebbles, sand, earth, wood, materials with elastoplastic properties such as tires or others.

Les gabions peuvent être pré-remplis. Dans ce cas, il n'est pas nécessaire de procéder au remplissage des gabions sur l'emplacement du chantier.Gabions can be pre-filled. In this case, it is not necessary to fill the gabions on the site of the site.

Ces gabions pré-remplis comportent alors une ou plusieurs sangles de levage pour la réalisation des différentes opérations de manutention qu'implique le transport de ces gabions pré-remplis du lieu de remplissage jusqu'au chantier puis leur positionnement dans l'ouvrage à réaliser. Par « sangle » on désigne ici tout moyen permettant le transport par suspension du gabion. Par exemple, il peut s'agir d'une élingue ou d'un câble.These pre-filled gabions then comprise one or more lifting straps for carrying out the various handling operations involved in transporting these pre-filled gabions from the filling site to the worksite and then positioning them in the work to be done. By "strap" is meant here any means for transporting suspension of the gabion. For example, it may be a sling or a cable.

Des gabions connus, formant un contenant pour un matériau de remplissage, comportent un fond grillagé s'étendant essentiellement dans un plan et au moins une face latérale délimitant le contenant, le fond grillagé étant formé de premiers fils s'étendant parallèlement à une direction X entrecroisés avec des seconds fils s'étendant parallèlement à une direction Y non colinéaire avec la direction X, les premiers fils étant espacés les uns des autres dans la direction Y de manière à former:

  • une ou deux rangées de mailles dites "porteuses", destinées à être chacune traversée par une sangle de levage attachée autour d'une barre de répartition pour permettre de soulever le gabion rempli par le matériau de remplissage, la ou les deux rangées porteuses étant symétriques par rapport à un plan de symétrie, le plan de symétrie étant de préférence parallèle à la direction X, perpendiculaire au plan dans lequel s'étend le fond grillagé et passant par le centre de gravité du gabion, et
  • des rangées de mailles dites "non-porteuses" parallèles, au moins l'une de ces rangées non-porteuses séparant les deux rangées porteuses lorsque le gabion comporte deux rangées porteuses.
Known gabions, forming a container for a filler material, have a grid bottom extending substantially in a plane and at least one side face delimiting the container, the grid bottom being formed of first son extending parallel to a direction X intertwined with second wires extending parallel to a non-collinear Y direction with the X direction, the first wires being spaced from each other in the Y direction to form:
  • one or two rows of "carrier" meshes, each intended to be traversed by a lifting strap fastened around a distribution bar to allow lifting of the gabion filled by the filling material, the one or both carrier rows being symmetrical compared to a plane of symmetry, the plan of symmetry being preferably parallel to the X direction, perpendicular to the plane in which the grid bottom extends and passing through the center of gravity of the gabion, and
  • so-called "non-carrier" mesh rows, at least one of these non-carrier rows separating the two carrier rows when the gabion has two carrier rows.

De tels gabions sont décrits dans les demandes de brevets FR2951750 et FR2951751 . La sangle de levage est, par exemple, une élingue dont l'extrémité se termine par une boucle dans laquelle est logée la barre de répartition.Such gabions are described in the patent applications FR2951750 and FR2951751 . The lifting strap is, for example, a sling whose end terminates in a loop in which is housed the distribution bar.

La ou les sangles de levage doivent être placées avant le remplissage du gabion, et positionnées précisément dans la ou les rangées porteuses. De tels gabions ne présentent pas de moyen simple et sûr pour l'ouvrier, de placer sans erreur et sans hésitation la ou les sangles de levage, de manière à garantir la répartition des charges et l'horizontalité du gabion lors de son déplacement.The lifting strap (s) must be placed before filling the gabion and positioned precisely in the carrier row (s). Such gabions do not present a simple and safe way for the worker, to place without error and without hesitation or lifting straps, so as to ensure the load distribution and horizontality of the gabion during its movement.

De l'état de la technique est également connu de : EP1186719A2 .From the state of the art is also known from: EP1186719A2 .

L'invention vise à remédier à cet inconvénient. Elle a donc pour objet un gabion conforme à la revendication 1.The invention aims to remedy this drawback. It therefore relates to a gabion according to claim 1.

Le fait que chaque rangée porteuse ou les deux rangées non-porteuses encadrant chaque rangée porteuse soient différentes visuellement des autres rangées non-porteuses du fond facilite le positionnement de la ou des sangles de levage et garantit un positionnement correct. Le bon positionnement de la ou des sangles de levage de manière symétrique par rapport au plan de symétrie passant par le centre de gravité du gabion assure la répartition des charges, l'équilibre et l'horizontalité du gabion lors d'un déplacement de celui-ci.The fact that each carrier row or the two non-carrier rows flanking each carrier row are visually different from the other non-bearing rows of the bottom facilitates the positioning of the lifting strap (s) and ensures correct positioning. The correct positioning of the lifting strap or straps symmetrically with respect to the plane of symmetry passing through the center of gravity of the gabion ensures the distribution of loads, balance and horizontality of the gabion during a displacement of this this.

Les modes de réalisation de ce gabion peuvent comporter une ou plusieurs des caractéristiques des revendications dépendantes.Embodiments of this gabion may include one or more of the features of the dependent claims.

Ces modes de réalisation du gabion présentent en outre les avantages suivants:

  • la présence d'un pli dans le fond destiné à recevoir la ou les barres de répartition permet d'éviter d'endommager la sangle de levage et rigidifie le fond et de garantir le bon positionnement de la barre de répartition,
  • la différence de largeur des rangées porteuses ou des deux rangées non-porteuses encadrant immédiatement chaque rangée porteuse, ou de nature ou du nombre de premiers fils délimitant ces rangées, ou du nombre de mailles dans ces rangées constituent des moyens simples pour repérer visuellement chaque rangée porteuse,
  • la largeur constante des rangées non-porteuses et une différence d'au moins un centimètre de la largeur de chaque rangée porteuse par rapport à celle des rangées non-porteuses garantissent la simplicité de fabrication du fond grillagé et une bonne visibilité de chaque rangée porteuse,
  • la largeur de chaque rangée porteuse inférieure d'au moins un centimètre à la largeur des autres rangées non-porteuses rend le fond du gabion plus solide au niveau de la rangée porteuse, destinée à être traversée par une sangle de levage afin de soulever le gabion rempli,
  • les mailles des rangées non-porteuses sur le fond grillagé de surface inférieure à celle des mailles des faces latérales permettent d'éviter la chute des petits cailloux contenus dans le matériau de remplissage même quand le gabion pré-rempli est vibro-compacté pour tasser le matériau de remplissage,
  • le fait de doubler les premiers fils délimitant chaque rangée porteuse par un fil supplémentaire accroît la solidité du fond du gabion au niveau de chaque rangée porteuse,
  • la présence d'un premier fil central séparant exactement le fond du gabion en deux parties de dimensions égales permet de faciliter la pose d'une cloison centrale dans le cas de gabion de grande longueur afin de le rigidifier.
These embodiments of the gabion also have the following advantages:
  • the presence of a fold in the bottom for receiving the distribution bar or bars avoids damaging the lifting strap and stiffens the bottom and ensure the correct positioning of the distribution bar,
  • the difference in width of the carrier rows or of the two non-carrier rows immediately surrounding each carrier row, or of nature or the number of first son defining these rows, or the number of meshes in these rows constitute simple means for visually identifying each row carrier,
  • the constant width of the non-loadbearing rows and a difference of at least one centimeter in width of each carrier row relative to that of the non-loadbearing rows guarantee the simplicity of manufacture of the grid bottom and good visibility of each carrier row,
  • the width of each carrier row is at least one centimeter smaller than the width of the other non-bearing rows, making the bottom of the gabion firmer at the level of the carrier, to be traversed by a lifting strap to lift the gabion filled,
  • the meshes of the non-supporting rows on the bottom of the grid surface lower than that of the meshes of the lateral faces make it possible to avoid the fall of small pebbles contained in the filling material even when the pre-filled gabion is vibro-compacted to compact the filling material,
  • doubling the first wires defining each carrier row with an additional wire increases the strength of the bottom of the gabion at each carrier row,
  • the presence of a first central wire exactly separating the bottom of the gabion in two parts of equal dimensions facilitates the installation of a central partition in the case of gabion of great length to stiffen it.

Dans la suite de cette description, les caractéristiques et fonctions bien connues de l'homme du métier ne sont pas décrites en détail.In the remainder of this description, the features and functions well known to those skilled in the art are not described in detail.

La figure 1 représente un gabion 2. Ce gabion 2 est destiné à être rempli avec un matériau de remplissage tel que des granulats, pierres ou tous autres matériaux afin de former un élément individuel de construction.The figure 1 is a gabion 2. This gabion 2 is intended to be filled with a filler material such as aggregates, stones or any other materials to form an individual building element.

La figure 1 est orientée selon un repère orthogonal XYZ.The figure 1 is oriented according to an orthogonal reference XYZ.

Ici, le gabion 2 est décrit dans le cas particulier où celui-ci a la forme d'un parallélépipède dont deux faces sont disposées horizontalement, dans le plan XY. La face inférieure du gabion 2 forme un fond plat 4 du gabion. L'essentiel du poids du matériau de remplissage repose sur ce fond 4 lorsque le gabion 2 est rempli. Ce fond 4 est plat, c'est-à-dire qu'il s'étend essentiellement parallèlement au plan XY. Ce plan XY, appelé ici « plan du fond » est confondu avec le plan du sol lorsque le gabion est déposé sur un sol plat et horizontal.Here, the gabion 2 is described in the particular case where it has the shape of a parallelepiped whose two faces are arranged horizontally in the XY plane. The lower face of the gabion 2 forms a flat bottom 4 of the gabion. Most of the weight of the filling material rests on this bottom 4 when the gabion 2 is filled. This bottom 4 is flat, that is to say it extends substantially parallel to the XY plane. This XY plane, called here "bottom plane" is confused with the ground plane when the gabion is placed on a flat and horizontal ground.

A partir du fond 4, quatre faces latérales 6 à 9 s'étendent verticalement.From the bottom 4, four lateral faces 6 to 9 extend vertically.

Le gabion 2 comporte, éventuellement, une face supérieure horizontale qui forme un couvercle pour refermer le gabion 2 après son remplissage. Cette face supérieure permet de retenir le matériau de remplissage à l'intérieur du contenant délimité par les faces 4, 6 à 9. Cette face supérieure ou couvercle n'a pas été représentée pour simplifier la figure 1.The gabion 2 comprises, optionally, a horizontal upper face which forms a lid for closing the gabion 2 after filling. This upper face makes it possible to retain the filling material inside the container delimited by the faces 4, 6 to 9. This upper face or lid has not been represented to simplify the figure 1 .

La hauteur du gabion dans la direction Z, notée H, est par exemple de 50 cm, 70 cm, 1 m, 1,2 m ou 1,5 m. La longueur horizontale du gabion dans la direction Y, notée L, est par exemple supérieure à 50 cm et de préférence supérieure ou égale à 1 m. La largeur horizontale du gabion dans la direction X, notée l, est par exemple supérieure ou égale à 30 cm et couramment de 50 cm, 70 cm et 1 m. La longueur L selon Y est supérieure ou égale à la largeur l selon X. Dans le mode de réalisation décrit ici, la longueur L du gabion est égale à 2 m, et sa largeur l est égale à 50 cm.The height of the gabion in the Z direction, denoted H, is for example 50 cm, 70 cm, 1 m, 1.2 m or 1.5 m. The horizontal length of the gabion in the Y direction, noted L, is for example greater than 50 cm and preferably greater than or equal to 1 m. The horizontal width of the gabion in the X direction, denoted l, is for example greater than or equal to 30 cm and commonly 50 cm, 70 cm and 1 m. The length L according to Y is greater than or equal to the width l according to X. In the embodiment described here, the length L of the gabion is equal to 2 m, and its width l is equal to 50 cm.

Le gabion 2 comporte ici une cloison centrale 10 verticale et située à mi-longueur. Cette cloison 10 permet de compartimenter et rigidifier le gabion 2 lorsque celui-ci a une longueur supérieure ou égale à 2 m.The gabion 2 here comprises a central vertical partition 10 and located at mid-length. This partition 10 can compartmentalize and rigidify the gabion 2 when it has a length greater than or equal to 2 m.

Le fond 4 du gabion comporte ici un pli 12 destiné à recevoir une barre de répartition 14 (figure 2) ainsi que des extrémités inférieures 16 et 18 de sangles de levage 20 et 22 (voir figure 2). Dans ce mode de réalisation, la barre 14 est amovible.The bottom 4 of the gabion here comprises a fold 12 intended to receive a distribution bar 14 ( figure 2 ) as well as lower ends 16 and 18 of lifting straps 20 and 22 (see figure 2 ). In this embodiment, the bar 14 is removable.

Le pli 12 s'étend parallèlement au plus grand côté du fond 4. Ici, le pli 12 s'étend d'un bord à l'autre du fond 4. Il a donc la même longueur L que celle du fond 4. Le pli 12 est symétrique par rapport à un plan parallèle au plan YZ qui contient le centre de gravité du gabion 2. Ici, le plan de symétrie 13 est confondu avec le plan contenant la cloison centrale 10.The fold 12 extends parallel to the largest side of the bottom 4. Here, the fold 12 extends from one edge to the other of the bottom 4. It therefore has the same length L as that of the bottom 4. The fold 12 is symmetrical with respect to a plane parallel to the plane YZ which contains the center of gravity of the gabion 2. Here, the plane of symmetry 13 coincides with the plane containing the central partition 10.

La barre 14 ne dépasse pas des faces verticales 6 et 8 du gabion. A cet effet, sa longueur est inférieure ou strictement inférieure à la longueur L du pli.The bar 14 does not protrude from the vertical faces 6 and 8 of the gabion. For this purpose, its length is less than or strictly less than the length L of the fold.

Ici, les sangles 20 et 22 sont des élingues formées chacune d'un câble souple, chaque câble étant lui-même constitué de torons formés de brins torsadés entre eux.Here, the straps 20 and 22 are slings each formed of a flexible cable, each cable being itself formed of strands formed strands twisted between them.

Comme représenté sur la figure 2, les sangles 20 et 22 comportent également, respectivement, des extrémités supérieures 24 et 26 destinées à être attachées à des moyens de levage du gabion 2. Ici, les extrémités 16, 18, 24 et 26 sont des boucles. La barre 14 traverse les boucles des extrémités 16 et 18. Ainsi, quand le gabion 2 est soulevé à l'aide des sangles 20 et 22, la barre de répartition 14 est tirée vers le haut ce qui l'enfonce dans le pli 12. Les sangles 20 et 22 traversent également l'intérieur du gabion. Ainsi, lorsque celui-ci est rempli, le matériau contenu à l'intérieur du gabion immobilise les sangles. En particulier, cela empêche les sangles de glisser le long de la barre de répartition 14.As shown on the figure 2 , the straps 20 and 22 also comprise, respectively, upper ends 24 and 26 intended to be attached to lifting means of gabion 2. Here, the ends 16, 18, 24 and 26 are loops. The bar 14 passes through the loops of the ends 16 and 18. Thus, when the gabion 2 is lifted using the straps 20 and 22, the distribution bar 14 is pulled upwards which drives it into the fold 12. The straps 20 and 22 also pass through the interior of the gabion. Thus, when it is full, the material contained inside the gabion immobilizes the straps. In particular, this prevents the straps from sliding along the distribution bar 14.

Les faces 6 à 9 et le fond 4 du gabion 2 ainsi que la cloison verticale 10 sont formées par du grillage. Les mailles de ce grillage sont choisies de manière à retenir le matériau de remplissage à l'intérieur du contenant. Ici, ce grillage est réalisé par des fils métalliques rigides horizontaux et verticaux soudés à angles droit les uns aux autres. Les mailles de ce grillage sont rectangulaires. Par exemple, les fils sont soudés à l'aide de moyen électrique (électrosoudure).The faces 6 to 9 and the bottom 4 of the gabion 2 and the vertical partition 10 are formed by wire mesh. The meshes of this mesh are chosen so as to retain the filling material inside the container. Here, this grid is made by horizontal and vertical rigid metal son welded at right angles to each other. The meshes of this grid are rectangular. For example, the wires are welded using electrical means (electrowelbing).

La taille des mailles du grillage est choisie, de préférence de manière à ce que les différentes hauteurs H, largeurs l et longueurs L possibles soient obtenues à l'aide d'un multiple entier de mailles. Ceci facilite la découpe et la réalisation des faces des gabions de différentes dimensions.The size of the mesh of the mesh is chosen, preferably so that the different heights H, widths I and lengths L possible are obtained using an integer multiple of meshes. This facilitates the cutting and the realization of the faces of the gabions of different dimensions.

Le grillage du fond 4 est formé de premiers fils 28 qui s'étendent selon la direction X, entrecroisés avec des seconds fils 30 qui s'étendent selon la direction Y. Les fils 30 sont ici tous identiques et dans ce mode de réalisation, les fils 28 sont également tous identiques. Les fils 28 et 30 sont ici des fils ayant une section circulaire, et de diamètres ici tous identiques. Par exemple, le diamètre de ces fils est supérieur à 2 mm et, de préférence supérieur à 3 ou 5 mm. Généralement, le diamètre des fils est inférieur à 1 ou 2 cm. Ces fils s'étendent le long d'un axe rectilignes. Les premiers fils 28 définissent des rangées de mailles. Une rangée est délimitée par deux fils du fond 4 parallèles à la direction X, immédiatement consécutifs et dont les projections orthogonales sur le plan XY sont séparés l'une de l'autre par un espace vide d'au moins 0,5 cm de largeur, et de préférence d'au moins 2 cm de largeur, dans la direction Y. Le fond 4 comporte deux types de rangées: des rangées porteuses et des rangées non-porteuses. Les rangées porteuses 32 et 34 sont les rangées destinées à être traversées respectivement par les sangles 20 et 22. Dans ce mode de réalisation, le gabion 2 comporte deux rangées porteuses. Les autres rangées 36 sont des rangées non-porteuses. Les rangées 36 sont ici toutes identiques avec une largeur lnp selon la direction Y constante, à l'exception des deux rangées 38 et 40 qui jouxtent à droite et à gauche la cloison 10. Dans ce mode de réalisation où le gabion 2 comporte une cloison centrale 10, un premier fil 28 sépare exactement le fond 4 du gabion en deux parties de longueurs égales selon la direction Y. Ce premier fil situé au milieu du fond 4 facilite la fixation de la cloison 10 et définit deux rangées non-porteuses 38 et 40, de largeurs inférieures à la largeur constante lnp des autres rangées 36 non-porteuses.The toasting of the bottom 4 is formed of first son 28 which extend in the direction X, intersecting with second son 30 which extend in the direction Y. The son 30 are here all identical and in this embodiment, the son 28 are also all identical. The son 28 and 30 are here son having a circular section, and diameters here all identical. For example, the diameter of these wires is greater than 2 mm and preferably greater than 3 or 5 mm. Generally, the diameter of the wires is less than 1 or 2 cm. These wires extend along a rectilinear axis. The first threads 28 define rows of stitches. A row is delimited by two yarns of the bottom 4 parallel to the X direction, immediately consecutive and whose orthogonal projections on the XY plane are separated from each other by a void space of at least 0.5 cm in width and preferably at least 2 cm wide, in the Y direction. The bottom 4 has two types of rows: carrier rows and non-carrier rows. The carrier rows 32 and 34 are the rows intended to be traversed respectively by the straps 20 and 22. In this embodiment, the gabion 2 comprises two carrier rows. The other rows 36 are non-bearing rows. The rows 36 are here all identical with a width l np in the constant Y direction, with the exception of the two rows 38 and 40 which adjoin to the right and left the partition 10. In this embodiment where the gabion 2 comprises a central partition 10, a first wire 28 exactly separates the bottom 4 of the gabion in two parts of equal lengths in the Y direction. This first wire located in the middle of the bottom 4 facilitates the fixing of the partition 10 and defines two non-bearing rows 38 and 40, widths smaller than the constant width l np of the other non-carrier rows 36.

Les deux rangées porteuses 32 et 34 sont symétriques par rapport au plan de symétrie 13 contenant la cloison 10. La symétrie des rangées porteuses 32 et 34 permet d'assurer l'équilibre du gabion 2 lorsque celui-ci est soulevé et déplacé grâce aux sangles 20 et 22. Plus précisément, ceci permet de maintenir le fond 4 sensiblement horizontal lorsque le gabion 2 est suspendu par les sangles 20 et 22. Le centre de gravité du gabion 2 est celui du gabion vide. Il se trouve dans le même plan parallèle au plan XZ que le centre de gravité du gabion rempli par le matériau de remplissage. L'éloignement des rangées porteuses 32 et 34 par rapport au plan de symétrie 13 varie avec la longueur L du gabion 2. Plus le gabion est long, plus les rangées porteuses sont éloignées du plan de symétrie 13 afin d'assurer un meilleur équilibre lors du transport du gabion soulevé par les sangles 20 et 22. Il est cependant intéressant d'avoir un éloignement constant des rangées porteuses, égal à 1 m par exemple, afin de standardiser les moyens de levage. Dans ce mode de réalisation, chaque rangée porteuse 32, 34 se trouve à plus de 30 cm du plan 13, et de préférence à plus de 40 cm, ou encore à plus de 50 cm du plan 13. Ici, par exemple, chaque rangée porteuse se trouve à 52,5 cm du plan de symétrie 13. Par distance entre le plan de symétrie 13 et une rangée porteuse, on entend ici la distance entre le plan 13 et le premier fil 28 délimitant la rangée porteuse le plus proche du plan 13.The two carrier rows 32 and 34 are symmetrical with respect to the plane of symmetry 13 containing the partition 10. The symmetry of the carrier rows 32 and 34 makes it possible to ensure the balance of the gabion 2 when the latter is raised and moved by means of the straps. 20 and 22. More precisely, this makes it possible to keep the bottom 4 substantially horizontal when the gabion 2 is suspended by the straps 20 and 22. The center of gravity of gabion 2 is that of the empty gabion. It lies in the same plane parallel to the XZ plane as the center of gravity of the gabion filled by the filling material. The distance of the carrier rows 32 and 34 from the plane of symmetry 13 varies with the length L of the gabion 2. The longer the gabion, the more the carrier rows are remote from the plane of symmetry 13 to ensure a better balance when the transport of the gabion raised by the straps 20 and 22. It is however interesting to have a constant distance of the carrier rows, equal to 1 m for example, to standardize the lifting means. In this embodiment, each carrier row 32, 34 is more than 30 cm from the plane 13, and preferably more than 40 cm, or more than 50 cm from the plane 13. Here, for example, each row carrier is at 52.5 cm from the plane of symmetry 13. By distance between the plane of symmetry 13 and a carrier row, here means the distance between the plane 13 and the first wire 28 defining the carrier row closest to the plane 13.

La largeur lp selon Y des rangées porteuses 32 et 34 est ici inférieure à lnp d'au moins un centimètre. Cette différence de largeur permet de repérer visuellement l'emplacement des deux rangées porteuses et la largeur plus étroite des rangées porteuses consolide le fond 4 du gabion à l'endroit où passent les sangles 20 et 22 pour le soulever.The width l p according to Y of the carrier rows 32 and 34 is here less than 1 np of at least one centimeter. This difference in width makes it possible to visually identify the location of the two carrier rows and the narrower width of the carrier rows consolidates the bottom 4 of the gabion where the straps 20 and 22 pass to lift it.

Ici, par exemple, la largeur lnp est égale à 5 cm. De préférence, la largeur lp est inférieure à 4 cm, ou encore à 3 cm. La largeur lp est cependant suffisante pour permettre le passage des sangles 20 et 22. Ici, les deux rangées non-porteuses 38 et 40 ont une largeur égale à 2,5 cm. Le fait que les rangées porteuses soient étroites limite également le glissement de la sangle dans la direction Y lors du déplacement du gabion.Here, for example, the width l np is equal to 5 cm. Preferably, the width l p is less than 4 cm, or even 3 cm. The width l p is however sufficient to allow the passage of the straps 20 and 22. Here, the two non-bearing rows 38 and 40 have a width equal to 2.5 cm. The fact that the carrier rows are narrow also limits the slippage of the strap in the Y direction when moving the gabion.

La dimension des mailles selon la direction X est, par exemple, de 10 cm.The mesh size in the X direction is, for example, 10 cm.

Les mailles des faces latérales 6 à 9 sont ici identiques à celles des rangées 36 non-porteuses du fond 4.The meshes of the lateral faces 6 to 9 are here identical to those of the non-bearing rows 36 of the bottom 4.

Un exemple possible de section transversale du pli 12 est représenté sur la figure 3. Sur la figure 3, la section transversale du pli 12 est triangulaire.A possible example of cross section of the fold 12 is shown on the figure 3 . On the figure 3 , the cross section of the fold 12 is triangular.

La figure 3 représente deux seconds fils 30 du grillage formant le fond 4. Sur cette figure, ils sont ici différenciés et numérotés 42 et 44. Sur la figure 3, seule la section transversale circulaire des fils 42 et 44 est visible. Les fils 42 et 44 s'étendent sur le plan du fond 4, c'est-à-dire sur le même plan que les autres fils destinés à reposer directement sur le sol ou sur un autre gabion. Les fils 42 et 44 sont donc situés sous les premiers fils 28 du fond 4. Sur la figure 3, seul un premier fil 28 est représenté. Ici, les fils 42 et 44 sont espacés l'un de l'autre d'une distance M, mesurée entre les axes respectifs des fils 42 et 44, égale à 10 cm. La distance M correspond à la dimension des mailles selon la direction X.The figure 3 represents two second wires 30 of the grid forming the bottom 4. In this figure, they are here differentiated and numbered 42 and 44. On the figure 3 only the circular cross-section of the wires 42 and 44 is visible. The son 42 and 44 extend on the plane of the bottom 4, that is to say on the same plane as the other son intended to rest directly on the ground or on another gabion. The wires 42 and 44 are therefore located under the first wires 28 of the bottom 4. On the figure 3 only a first wire 28 is shown. Here, the wires 42 and 44 are spaced from each other by a distance M, measured between the respective axes of the wires 42 and 44, equal to 10 cm. The distance M corresponds to the mesh size in the X direction.

Ici, tous les premiers fils 28 sont pliés entre les fils 42 et 44 pour former le pli 12. Le sommet du pli est, par exemple, situé à mi-distance entre les fils 42 et 44. La profondeur maximale P du pli 12 est strictement supérieure au cumul du diamètre de la barre 14 avec le diamètre de la section transversale de la boucle formant l'extrémité 16 de la sangle. Ainsi, lorsque le gabion 2 est soulevé à l'aide de la sangle 20, l'extrémité 16 est entièrement située au-dessus du plan du fond 4. Par exemple, la profondeur P est supérieure ou égale à 20 mm et, de préférence, supérieure ou égale à 30 ou 40 mm.Here, all the first threads 28 are folded between the threads 42 and 44 to form the fold 12. The crown of the fold is, for example, located midway between the threads 42 and 44. The maximum depth P of the fold 12 is strictly greater than the accumulation of the diameter of the bar 14 with the diameter of the cross section of the loop forming the end 16 of the strap. Thus, when the gabion 2 is raised using the strap 20, the end 16 is entirely located above the plane of the bottom 4. For example, the depth P is greater than or equal to 20 mm and preferably , greater than or equal to 30 or 40 mm.

Les figures 4 à 8 illustrent chacune un gabion identique au gabion 2 sauf que le fond 4 est remplacé par un autre fond différent et que la cloison 10 est omise. Pour simplifier les figures 4 à 8, seul le fond du gabion est représenté.The Figures 4 to 8 each illustrate a gabion identical to gabion 2 except that the bottom 4 is replaced by another different bottom and the partition 10 is omitted. To simplify Figures 4 to 8 only the bottom of the gabion is represented.

Le gabion décrit figure 4 est identique au gabion 2 à l'exception du fait que le fond 4 est remplacé par un fond grillagé 50. Dans ce mode de réalisation, la surface des mailles des rangées non-porteuses 52 du fond 50 est de préférence inférieure à la surface des mailles des faces latérales 6 à 9. Cette caractéristique permet d'éviter la chute des plus petits cailloux constituant le matériau de remplissage du gabion à travers le fond 50 du gabion. Les mailles des rangées 52 sont de préférence 1,5 fois plus petites que celles des faces latérales. Leur dimension est 2,5 x 10 cm. Leur dimension peut aussi être de 2,5 x 5 cm si l'on double le nombre de fils du fond s'étendant dans la direction Y.The gabion describes figure 4 is identical to the gabion 2 except that the bottom 4 is replaced by a grid bottom 50. In this embodiment, the mesh surface of the non-bearing rows 52 of the bottom 50 is preferably smaller than the surface of the meshes side faces 6 to 9. This feature prevents the fall of smaller stones constituting the gabion filling material through the bottom 50 of the gabion. The stitches of the rows 52 are preferably 1.5 times smaller than those of the lateral faces. Their dimension is 2.5 x 10 cm. Their size can also be 2.5 x 5 cm if the number of bottom wires extending in the Y direction is doubled.

Le fond 50 comporte ici deux rangées porteuses 54 et 56, dont la largeur lp est supérieure à la largeur lnp des rangées 52 dans la direction Y, la figure 4 étant orientée selon le repère orthogonal XY où la plus grande longueur du gabion L s'étend dans la direction Y. La longueur L du gabion est supérieure ou égale à 0,5 m, et de préférence supérieure à 1 m. Ici, la longueur L est égale à 2 m. De préférence, la largeur lp est supérieure d'au moins un centimètre à lnp, ou encore d'au moins 2 cm. Ici, la largeur lp est deux fois plus grande que la largeur lnp, elle est supérieure de 2,5 cm à lnp. Les rangées 54 et 56 sont identiques et seule la rangée 56 est décrite plus en détail. Sur cette figure 4, les fils 28 qui délimitent la rangée 56 à droite et à gauche dans la direction X portent les références 57A et 57B.The bottom 50 here comprises two carrier rows 54 and 56, whose width l p is greater than the width l np of the rows 52 in the Y direction, figure 4 being oriented along the orthogonal XY coordinate system where the longest length of the gabion L extends in the Y direction. The length L of the gabion is greater than or equal to 0.5 m, and preferably greater than 1 m. Here, the length L is equal to 2 m. Preferably, the width p is greater by at least one centimeter at 1 np , or at least 2 cm. Here, the width l p is twice as large as the width l np , it is 2.5 cm greater than l np . Rows 54 and 56 are identical and only row 56 is described in more detail. On this figure 4 the wires 28 delimiting the row 56 on the right and on the left in the X direction bear the references 57A and 57B.

Pour consolider le fond 50 au niveau des rangées porteuses 54 et 56 et marquer l'emplacement de ces rangées 54 et 56, chaque fil 57A et 57B est doublé par un fil supplémentaire 58A et 58B qui s'étend dans la direction X. Ici, les fils 57A, 57B, 58A et 58B sont tous identiques. Les fils 58A et 58B se trouvent typiquement à moins de 5 mm respectivement de chacun des fils 57A, 57B. Si possible, les fils 58A et 58B sont en contact direct respectivement avec les fils 57A et 57B. Ici, les fils 58A et 58B jouxtent respectivement les fils 57A et 57B, sur l'extérieur de la rangée porteuse 56. Les fils 58A et 58B se situent donc chacun dans une des rangées non-porteuses 52, qui jouxte la rangée porteuse 56. Ces deux rangées non-porteuses portent ici les références 59A et 59B. La largeur des rangées 59A et 59B est donc légèrement inférieure à la largeur des autres rangées porteuses 52 de par la présence des fils 58A et 58B. Les fils consécutifs 57A et 58A, ainsi que 57B et 58B, ne définissent pas ici une nouvelle rangée, telle que définie en regard de la figure 1. En effet, les projections orthogonales sur le plan XY des fils 57A et 58A, respectivement 57B et 58B, sont séparées l'une de l'autre par une distance inférieure à 0,5 cm.To consolidate the bottom 50 at the level of the carrier rows 54 and 56 and mark the location of these rows 54 and 56, each wire 57A and 57B is doubled by an additional wire 58A and 58B which extends in the X direction. the wires 57A, 57B, 58A and 58B are all identical. The wires 58A and 58B are typically less than 5 mm respectively from each of the wires 57A, 57B. If possible, the son 58A and 58B are in direct contact respectively with the son 57A and 57B. Here, the wires 58A and 58B respectively adjoin the wires 57A and 57B, on the outside of the carrier row 56. The wires 58A and 58B are each located in one of the non-carrier rows 52, which adjoins the carrier row 56. These two non-carrier rows are here references 59A and 59B. The width of the rows 59A and 59B is therefore slightly smaller than the width of the other carrier rows 52 by the presence of the son 58A and 58B. The consecutive wires 57A and 58A, as well as 57B and 58B, do not define here a new row, as defined with respect to the figure 1 . Indeed, the orthogonal projections on the XY plane of the son 57A and 58A, respectively 57B and 58B, are separated from each other by a distance less than 0.5 cm.

La figure 5 représente un fond 60. Dans ce mode de réalisation, le gabion a une longueur égale à 1 m. Le fond 60 a donc lui aussi une longueur L selon la direction Y égale à 1 m.The figure 5 represents a bottom 60. In this embodiment, the gabion has a length equal to 1 m. The bottom 60 also has a length L along the Y direction equal to 1 m.

Etant donnée la faible longueur du gabion, celui-ci comporte une seule sangle de levage et le fond 60 comporte une seule rangée porteuse 62. La rangée 62 est symétrique par rapport à un plan de symétrie du gabion parallèle à X et contenant le centre de gravité du gabion. La rangée 62 est encadrée immédiatement à droite et à gauche par deux rangées non-porteuses 64 et 66. Les rangées 64 et 66 diffèrent visuellement des autres rangées non-porteuses 68, ici, par leur largeur selon Y. La largeur des rangées 64 et 66 diffère d'au moins un centimètre par rapport à la largeur des autres rangées non-porteuses 68, et de préférence d'au moins 1,5 cm ou encore d'au moins 2 cm. Ici, la largeur des rangées 64 et 66 est inférieure à celle des rangées 68 de 2,5 cm. Dans ce mode de réalisation, les mailles des rangées non-porteuses 68 ont des dimensions égales à 5 cm selon Y et 10 cm selon X. La rangée porteuse 62 comporte des mailles de mêmes dimensions. La largeur des rangées 64 et 66 selon Y est égale à 2,5 cm.Given the short length of the gabion, it has a single lifting strap and the bottom 60 has a single carrier row 62. The row 62 is symmetrical with respect to a plane of symmetry of the gabion parallel to X and containing the center of gravity of the gabion. The row 62 is framed immediately to the right and left by two non-bearing rows 64 and 66. The rows 64 and 66 differ visually from the other non-bearing rows 68, here, by their width along Y. The width of the rows 64 and 66 differs by at least one centimeter from the width of the other non-carrier rows 68, and preferably at least 1.5 cm or at least 2 cm. Here, the width of the rows 64 and 66 is smaller than that of the rows 68 of 2.5 cm. In this embodiment, the meshes of the non-carrier rows 68 have dimensions equal to 5 cm along Y and 10 cm according to X. The carrier row 62 has meshes of the same dimensions. The width of the rows 64 and 66 along Y is equal to 2.5 cm.

La figure 6 représente un fond 69. Le fond 69 est identique au fond 4 sauf que chaque rangée porteuse diffère visuellement des rangées non-porteuses par la nature des premiers fils la délimitant. Sur la figure 6, seule une rangée porteuse 70 est représentée. Elle est délimitée à droite et à gauche dans la direction Y par des premiers fils 74 et 76. Ici, par exemple, les autres fils 28 ont une section transversale circulaire alors que les fils 74 et 76 ont une section transversale rectangulaire, carrée ou ovale.The figure 6 is a bottom 69. The bottom 69 is identical to the bottom 4 except that each carrier row differs visually non-bearing rows by the nature of the first son delimiting. On the figure 6 only one carrier row 70 is shown. It is delimited to the right and left in the Y direction by first son 74 and 76. Here, for example, the other son 28 have a circular cross section while the son 74 and 76 have a rectangular cross section, square or oval .

La figure 7 représente un fond 80 d'un gabion dans lequel le pli 12 comporte un second fil 82 en son sommet, qui s'étend sur toute la longueur du pli. Dans ce mode de réalisation, les deux rangées porteuses portent les références 84 et 86. Le fil 82 est coupé et enlevé à l'intérieur de chaque rangée porteuse, sur toute sa largeur, créant ainsi un nombre de mailles différent dans les rangées porteuses par rapport au nombre de mailles des autres rangées non-porteuses 36. Ici, les rangées 84 et 86 comportent une maille de moins que les rangées non-porteuses 36.The figure 7 represents a bottom 80 of a gabion in which the fold 12 has a second wire 82 at its top, which extends over the entire length of the fold. In this embodiment, the two carrier rows bear the references 84 and 86. The thread 82 is cut and removed within each carrier row, over its entire width, thus creating a different number of stitches in the carrier rows by number of meshes of the other non-bearing rows 36. Here, the rows 84 and 86 have one less mesh than the non-carrier rows 36.

La figure 8 représente un fond 90. Le fond 90 est identique au fond 4 sauf que les premiers fils 28 du fond 90 sont situés en-dessous des seconds fils 30 et chaque rangée porteuse diffère visuellement des rangées non-porteuses par le nombre de fils la délimitant. Sur la figure 8, seule une rangée porteuse 92 est représentée. Elle est délimitée à droite et à gauche dans la direction Y par des premiers fils 94 et 96. Chacun de ces fils 94 et 96 est doublé par un fil supplémentaire, respectivement 98 et 100, s'étendant dans la direction X. Les fils 28, 94, 96, 98 et 100 sont ici tous identiques. Les fils 98 et 100 se situent immédiatement au-dessus du second fil 30, à la verticale des fils 94 et 96. Les projections orthogonales sur le plan XY des fils 94 et 98, respectivement 96 et 100, sont à moins de 0,5 cm l'une de l'autre. Les fils 98 et 100 sont en contact direct avec le fil 30.The figure 8 is a bottom 90. The bottom 90 is identical to the bottom 4 except that the first son 28 of the bottom 90 are located below the second son 30 and each carrier row differs visually non-bearing rows by the number of son delimiting. On the figure 8 only one carrier row 92 is represented. It is delimited to the right and left in the Y direction by first son 94 and 96. Each of these son 94 and 96 is doubled by an additional wire, respectively 98 and 100, extending in the direction X. The son 28 , 94, 96, 98 and 100 are all identical here. The wires 98 and 100 are immediately above the second wire 30, vertical to the wires 94 and 96. The orthogonal projections on the XY plane of the wires 94 and 98, respectively 96 and 100, are within 0.5 cm from each other. The wires 98 and 100 are in direct contact with the wire 30.

De nombreux autres modes de réalisation sont possibles.Many other embodiments are possible.

Le gabion peut avoir d'autres formes qu'un parallélépipède. Par exemple, le gabion peut avoir plus de quatre côtés verticaux. Cela peut être le cas lorsque celui-ci a la forme d'un polyèdre à plus de six faces. Le gabion peut aussi avoir la forme d'une colonne dont la section horizontale est circulaire.The gabion can have other forms than a parallelepiped. For example, the gabion can have more than four vertical sides. This can be the case when it has the shape of a polyhedron with more than six faces. The gabion can also be in the form of a column whose horizontal section is circular.

Le plan de symétrie 13 n'est pas nécessairement parallèle à la direction X.The plane of symmetry 13 is not necessarily parallel to the X direction.

Le couvercle du gabion peut être omis.The lid of the gabion can be omitted.

De préférence, les seconds fils 42, 44 sont situés au-dessus des premiers fils 28, et non pas en-dessous comme représenté sur la figure 3.Preferably, the second wires 42, 44 are located above the first wires 28, and not below as shown in FIG. figure 3 .

En variante, le pli s'étend parallèlement à la direction X.In a variant, the fold extends parallel to the direction X.

Le pli ne s'étend pas nécessairement sur toute la longueur L du fond du gabion. Le pli peut aussi être omis. Dans ce cas, la barre de répartition se trouve en-dessous du plan du fond. Le pli peut aussi être remplacé par une nervure. Dans un cas particulier, cette nervure est en sailli vers l'extérieur du gabion par rapport au plan du fond pour rigidifier le fond. Par exemple, cette nervure est aussi obtenue par pliage des fils du fond 4 mais dans une direction opposée à celle nécessaire pour obtenir un pli, tel que le pli 12.The fold does not necessarily extend over the entire length L of the bottom of the gabion. The fold can also be omitted. In this case, the distribution bar is below the bottom plane. The fold can also be replaced by a rib. In a particular case, this rib is projecting towards the outside of the gabion relative to the plane of the bottom to stiffen the bottom. For example, this rib is also obtained by folding the threads of the bottom 4 but in a direction opposite to that necessary to obtain a fold, such as the fold 12.

La barre 14 peut être constituée de plusieurs tronçons alignés. Par exemple, la barre est tronçonnée en segments de seulement 20 cm.The bar 14 may consist of several aligned sections. For example, the bar is cut into segments of only 20 cm.

En variante, la barre de répartition est fixée sans aucun degré de liberté au fond du gabion. Par exemple, la barre de répartition est un fil du fond parallèle à la direction Y, identique ou non aux autres fils parallèles à la direction Y. Par exemple, lorsque la barre de répartition est aussi un fil du fond, ce fil présente un diamètre plus important pour le renforcer.Alternatively, the distribution bar is fixed without any degree of freedom to the bottom of the gabion. For example, the distribution bar is a yarn of the bottom parallel to the Y direction, identical or not to other yarns parallel to the Y direction. For example, when the distribution bar is also a bottom wire, this wire has a diameter more important to strengthen it.

La section transversale de la sangle peut être rectangulaire, circulaire ou de toute autre forme appropriée.The cross section of the strap may be rectangular, circular or any other suitable form.

La sangle n'est pas nécessairement souple, c'est-à-dire capable de se déformer sous son propre poids. Elle peut aussi être réalisée à l'aide d'une barre ou d'un tube rigide présentant un crochet ou une anse à l'une de ses extrémités.The strap is not necessarily flexible, that is to say able to deform under its own weight. It can also be carried out using a bar or a rigid tube having a hook or a loop at one of its ends.

Le matériau utilisé pour réaliser la sangle n'est pas nécessairement un métal mais peut aussi être un matériau synthétique ou autres (Kevlar, ... etc.) présentant une résistance mécanique appropriée pour permettre de soulever le poids du gabion 2.The material used to make the strap is not necessarily a metal but can also be a synthetic material or others (Kevlar, ... etc.) having a suitable mechanical strength to lift the weight of gabion 2.

La sangle de levage est attachée autour de la barre de répartition. Par le terme "attaché", on couvre le cas où l'extrémité de la sangle est une boucle autour de la barre de répartition mais aussi les cas où l'extrémité de la sangle est nouée ou enroulée autour de la barre, ou encore reliée à la barre par une manille ou autre.The lifting strap is tied around the distribution bar. By the term "attached", we cover the case where the end of the strap is a loop around the distribution bar but also cases where the end of the strap is tied or wrapped around the bar, or connected at the helm by a shackle or other.

La sangle peut être une seule grande élingue qui fait le tour de la barre de répartition et dont les deux extrémités tangentent le dessus ou dépassent au-dessus du gabion.The strap can be a single large sling that goes around the bar and whose two ends tangent to the top or protrude above the gabion.

Les faces latérales du gabion peuvent ne pas être grillagées.The side faces of the gabion may not be screened.

Les rangées non-porteuses 36 peuvent avoir des largeurs différentes entre elles.The non-carrier rows 36 may have different widths between them.

Les dimensions des mailles non-porteuses peuvent être différentes. Par exemple, leur dimension peut être 5 x 5 cm.The dimensions of the non-carrier meshes may be different. For example, their size may be 5 x 5 cm.

Les premiers fils 28 peuvent être différents des seconds fils 30.The first threads 28 may be different from the second threads 30.

La section des premiers fils 74 et 76 délimitant chaque rangée porteuse peut être rectangulaire, avec une plus grande hauteur verticale, par exemple, ou encore circulaire mais avec un diamètre différent de celui des autres premiers fils 28.The section of the first son 74 and 76 delimiting each carrier row may be rectangular, with a greater vertical height, for example, or circular but with a different diameter than the other first son 28.

Tous les fils du fond, aussi bien des rangées porteuses que non-porteuses, peuvent aussi avoir une section carrée ou rectangulaire avec la plus grande hauteur verticale.All bottom wires, both carrier and non-carrier rows, may also have a square or rectangular section with the greatest vertical height.

Les caractéristiques décrites ci-dessus peuvent être associées dans un même fond de gabion, autrement que dans les modes de réalisation décrits ici. Par exemple, chaque rangée porteuse peut être plus étroite que les rangées non-porteuses, avec des premiers fils délimitant chaque rangée porteuse ayant une section différente des autres premiers fils.The features described above may be associated in the same gabion background, other than in the embodiments described herein. For example, each carrier row may be narrower than the non-carrier rows, with first leads defining each carrier row having a different section from the other first leads.

L'usage de mailles de surface inférieure sur le fond du gabion par rapport à celles des faces latérales peut être mis en oeuvre indépendamment du fait que les rangées porteuses soient différentes des autres rangées non-porteuses.The use of lower surface meshes on the bottom of the gabion relative to those of the side faces can be implemented independently of the fact that the carrier rows are different from the other non-carrier rows.
