- FIG. 3d and 3d respectively correspond to the start phase of gabion filling ( figure 3d ), triggered by the arrival on the third end-of-travel contact (22), and the activation of the vibration of the table (2) ( figure 3e ) after a delay.
- the hopper (4) on the frame (7) then moves alternately in one direction and the other ( Figures 3f and 3g ) so as to cover in each direction the entire dimension of the gabions in the direction of travel.
- the filling is therefore optimized, thanks to this "topping" made by several round trips.
- This topping is completely configurable via a PLC. It is possible to program the number of round trips, the speed of movement of the hopper, the speed of loading and the speed of settlement. A finishing operation of the load for a few seconds is implemented in the position illustrated in FIG. figure 3h .

Description
La présente invention a trait à un dispositif de fabrication de gabions par remplissage de cages par des pierres, suivi d'un compactage de ces pierres dans les cages. Un gabion consiste en fait en une cage métallique, en général d'allure parallélépipédique, constituée d'un maillage en fils de métal tressés ou soudés, remplie de pierres de tailles variables. Ces gabions sont utilisés dans diverses applications comme les accotements de routes ou de voies fluviales, l'érection rapide et à moindre frais de murs à vocation fonctionnelle ou décorative etc., ouvrages dans lesquels on tire au surplus partie de leur robustesse.The present invention relates to a device for making gabions by filling cages with stones, followed by compaction of these stones in the cages. A gabion consists in fact of a metal cage, generally of parallelepipedic appearance, consisting of a mesh of braided or welded metal wires, filled with stones of varying sizes. These gabions are used in various applications such as the shoulders of roads or waterways, the erection quickly and cheaply of functional or decorative walls etc., works in which one draws part of their robustness.
Leur structure « lacunaire », due aux espaces résiduels subsistant entre les pierres naturelles qui les composent, les rend particulièrement adaptés aux usages de stabilisation qui nécessitent ou permettent un passage de liquides comme l'eau ou des boues. Ainsi, ils servent notamment à lutter contre l'érosion des berges, retenant les sols sans constituer d'obstacle pour les liquides. Leur capacité à drainer des liquides permet par ailleurs leur utilisation dans des environnements propices aux éboulements, voire leur emploi comme pare-avalanche.Their "lacunary" structure, due to residual spaces remaining between the natural stones that compose them, makes them particularly suitable for stabilization uses that require or allow the passage of liquids such as water or sludge. Thus, they serve in particular to fight against erosion of the banks, retaining the soil without constituting an obstacle for liquids. Their ability to drain liquids also allows their use in environments prone to landslides, or their use as an avalanche barrier.
Ils manifestent en outre des fortes capacités d'absorption acoustique, et sont également utilisés comme écrans anti-bruit, cette fonction pouvant le cas échéant être couplée à un aménagement paysager. Dans certaines hypothèses, ils sont d'ailleurs utilisés exclusivement pour leur capacité d'intégration au paysage, leur structure étant propice à une colonisation végétale, donnant un aspect plus naturel au mur ou à la berge qui en est constitué(e).They also exhibit strong sound absorption capabilities, and are also used as noise barriers, this function can optionally be coupled with landscaping. In some cases, they are used exclusively for their ability to integrate with the landscape, their structure being conducive to plant colonization, giving a more natural appearance to the wall or the bank that is constituted (e).
Enfin, dans une société de plus en plus soucieuse de préserver son environnement naturel, il s'agit d'un produit « vert » puisque son utilisation n'est pas susceptible d'effets défavorables en termes environnementaux : en l'absence de constituants autres que le treillis métallique et les pierres naturelles, les gabions présentent l'avantage de ne pas contenir de composants d'origine chimique tels que par exemple du ciment, dont on sait qu'il dégage du monoxyde de carbone dans l'atmosphère.Finally, in a society increasingly concerned about preserving its natural environment, it is a "green" product since its use is not likely to have adverse effects in environmental terms: in the absence of other constituents metal mesh and natural stones, gabions have the advantage of not containing components of chemical origin such as for example cement, which is known to release carbon monoxide in the atmosphere.
Pour que les gabions puissent remplir leur rôle, notamment sur un plan mécanique dans les différents usages qui en sont faits, il importe que le remplissage des cages s'accompagne d'un compactage correctement réalisé, afin que les gabions puissent le cas échéant être superposés sans que les cages ne soient déformées par écrasement. La modification du volume initial qui en résulterait, dont le contour est précisément donné par la cage métallique, empêcherait de les utiliser comme « briques élémentaires » de construction dans des structures dans lesquelles ils sont juxtaposés et empilés.In order for the gabions to fulfill their role, especially on a mechanical level in the various uses that are made of it, it is important that the filling of the cages is accompanied by a compaction properly carried out, so that the gabions can be superimposed if necessary without the cages being deformed by crushing. The resulting modification of the initial volume, whose contour is precisely given by the metal cage, prevents them from being used as "elementary building blocks" in structures in which they are juxtaposed and stacked.
Le remplissage est par conséquent une opération importante déterminant in fine la qualité des gabions. L'homogénéité du gabion résulte du tassage / compactage, le but étant que le taux de remplissage obtenu puisse garantir une tenue mécanique correcte au produit fini.Filling is therefore an important operation ultimately determining the quality of the gabions. The homogeneity of the gabion results from tamping / compaction, the aim being that the filling rate obtained can guarantee a correct mechanical resistance to the finished product.
Jusqu'ici, les procédés de remplissage de gabion obéissent à des logiques assez rudimentaires, le remplissage s'effectuant - gabion par gabion -de manière individuelle, au mieux à l'aide d'un moyen mécanisé tel qu'une pelleteuse, la cage étant localisée au moment de son remplissage sur une plate-forme vibrante réalisant le compactage à mesure du remplissage. D'autres moyens sont éventuellement mis en oeuvre de façon indépendante pour la mise en place de la cage vide, puis pour son transfert à l'état rempli. L'ensemble de ces opérations ne procède cependant guère d'une logique industrielle.So far, the gabion filling processes obey rather rudimentary logics, the filling taking place - gabion gabion - individually, at best using a mechanized means such as a backhoe, the cage being located at the time of its filling on a vibrating platform performing compaction as filling. other means are optionally implemented independently for the establishment of the empty cage, then for its transfer to the filled state. All of these operations, however, hardly proceed from an industrial logic.
La présente invention remédie à cette carence en proposant un dispositif de fabrication de gabions qui se caractérise à titre principal en ce qu'il comporte :
- une table vibrante composée d'un plancher sur lequel est fixé un caisson dont la paroi périphérique d'allure verticale entoure au moins une cage métallique et de moyens de vibration de ce plancher ;
- une trémie de stockage à la base de laquelle sont disposés des extracteurs ;
- des moyens d'entrainement aptes à déplacer la trémie entre au moins une position de remplissage de la ou des cages métalliques et une position de remplissage de la trémie, à distance du ou des gabions.
- a vibrating table composed of a floor on which is fixed a box whose peripheral wall of vertical shape surrounds at least one metal cage and means of vibration of this floor;
- a storage hopper at the base of which extractors are arranged;
- driving means capable of moving the hopper between at least one filling position of the metal cage or cages and a filling position of the hopper, at a distance from the gabion or gabions.
L'ensemble trémie / extracteurs / moyens d'entraînement aptes à déplacer la trémie permet de rendre l'opération de remplissage plus industrielle dans la mesure où elle obéit à chaque étape à une forme d'automatisation des opérations, comme on le verra plus en détail dans la suite. L'invention combine les opérations nécessaires à la réalisation de la totalité des étapes nécessaires à la fabrication du produit fini, à savoir le gabion. La trémie peut d'ailleurs elle-même être disposée à l'extrémité d'une rampe de déchargement qui ajoute encore à cet aspect industrialisé.The hopper / extractor / drive unit capable of moving the hopper makes the filling operation more industrial in that it obeys at each step a form of automation of operations, as will be seen in more detail. detail in the following. The invention combines the operations necessary to achieve all the steps necessary for the manufacture of the finished product, namely the gabion. The hopper can itself be arranged at the end of an unloading ramp which adds to this industrialized aspect.
Pour faciliter le chargement/déchargement des cages en treillis métallique, vides en début de cycle de remplissage et pleines en fin dudit cycle, une portion de la paroi du caisson constitue une porte pivotable par rapport au reste de la paroi entre une position de fermeture pour le remplissage et le compactage du ou des gabions et une position d'ouverture et d'extraction du ou des gabions.To facilitate the loading / unloading of wire mesh cages, empty at the beginning of the filling cycle and filled at the end of said cycle, a portion of the wall of the box constitutes a pivotable door relative to the remainder of the wall between a closed position for filling and compacting the gabion (s) and an opening and extraction position of the gabion (s).
Plus précisément, la porte est verrouillable en position fermée à l'aide d'un système de fermeture comportant :
- au moins deux boulons placés au niveau des chants libres respectivement de la porte et du reste de la paroi du caisson, l'arbre fileté prévu pour coopérer avec un écrou de chaque boulon étant manoeuvrable à la main au moyen d'un organe de préhension ;
- un dispositif de positionnement de la porte par rapport au reste de la paroi rendant les arbre filetés et leurs écrous respectifs coaxiaux ; et
- une came rotative par rapport à la porte, disposée à proximité du chant inférieur de la porte, actionnable par un levier et dont la rotation provoque la mise en contact de la périphérie de la came et du plancher.
- at least two bolts placed at the level of the free edges respectively of the door and the rest of the wall of the box, the threaded shaft provided to cooperate with a nut of each bolt being operable manually by means of a gripping member;
- a device for positioning the door relative to the remainder of the wall making the threaded shaft and their respective nuts coaxial; and
- a cam rotating relative to the door, disposed near the lower edge of the door, actuable by a lever and whose rotation causes the contact of the periphery of the cam and the floor.
L'enjeu est de mettre en place un système d'ouverture / fermeture manuel d'utilisation très simple et immédiate, qui soit en même temps compatible mécaniquement avec les vibrations communiquées par la table vibrante. A cet égard, l'organe de préhension peut être constitué de leviers radiaux, à la manière d'un volant dépourvu de couronne. Le dispositif de positionnement peut prendre la forme d'un système de coins de centrage, un coin central solidarisé à l'un de la porte ou du reste de la paroi s'insérant entre deux coins solidarisés à l'autre. La came est prévue pour mettre le système en tension, et éviter ainsi une ouverture intempestive due aux vibrations.The challenge is to set up a system of opening / closing manual very simple and immediate use, which is at the same time mechanically compatible with the vibrations communicated by the vibrating table. In this respect, the gripping member may consist of radial levers, in the manner of a steering wheel without a crown. The positioning device may take the form of a system of centering corners, a central corner secured to one of the door or the rest of the wall inserted between two wedges secured to one another. The cam is intended to put the system in tension, and thus avoid inadvertent opening due to vibrations.
Selon une possibilité, le plancher est muni d'orifices d'évacuation des résidus se détachant des pierres lors du remplissage et du compactage. Tous les cailloux résiduels dont les dimensions ne sont pas compatibles avec la constitution du gabion sont ainsi évacués. Lesdits résidus pierreux sont ensuite guidés par une auge solidaire de la table vers un bac de récupération situé sous la table.According to one possibility, the floor is provided with outlets for removing residues from the stones during filling and compaction. Any residual stones whose dimensions are not compatible with the constitution of the gabion are thus evacuated. Said stony residues are then guided by a trough secured to the table to a recovery tank located under the table.
Selon une possibilité optionnelle, ces résidus pierreux peuvent être guidés par ladite auge vers un transporteur à bande ou vibrant solidaire de la table et conduisant les résidus vers un bac de récupération placé au voisinage de ladite table. Cette configuration présente l'avantage de permettre une évacuation plus simple du bac de récupération lorsqu'il est plein.According to an optional possibility, these stony residues may be guided by said trough to a belt or vibrating conveyor integral with the table and leading the residues to a recovery tank placed in the vicinity of said table. This configuration has the advantage of allowing a simpler evacuation of the recovery tank when it is full.
Dans une configuration possible, les moyens de vibration de la table vibrante sont constitués d'au moins un motovibrateur supporté par une poutre réalisée en profilés de forte section appartenant au support de la table. Ladite poutre est en fait dimensionnée de manière à supporter le dispositif d'excitation. Celui-ci est en fait de préférence composé de deux motovibrateurs. Le plancher de la table est par ailleurs placé de manière classique sur des moyens de suspension.In one possible configuration, the vibration means of the vibrating table consist of at least one vibrator supported by a beam made of sections of high section belonging to the support of the table. Said beam is in fact sized to support the excitation device. This is in fact preferably composed of two vibrators. The floor of the table is also placed in a conventional manner on suspension means.
En sus du caisson contenant le ou les gabions, le dispositif de remplissage de l'invention comporte comme mentionné une trémie qui englobe un volume compris entre 8 m3 et 12 m3, et comporte des parois d'allure verticale en partie supérieure et des parois inclinées d'un angle compris entre 50° et 70° en partie inférieure.In addition to the box containing the gabion or gabions, the filling device of the invention comprises, as mentioned, a hopper that includes a volume of between 8 m 3 and 12 m 3 , and has walls of vertical shape at the top and walls inclined at an angle of between 50 ° and 70 ° in the lower part.
Elle est donc configurée de manière à faciliter le trajet de pierres de dimensions adéquates pour la constitution de gabions vers le bas de la trémie, en vue de leur extraction à destination des cages métalliques. Ladite trémie est supportée par une charpente munie de 4 roues aptes à rouler sur une paire de rails parallèles. De préférence, les deux roues arrière sont motorisées au moyen chacune d'un motoréducteur localisé à leur voisinage. Selon une variante possible, une seule des deux roues arrière est motorisée au moyen d'un motoréducteur localisé à son voisinage, l'entraînement de l'autre roue arrière s'effectuant via un arbre traversant.It is therefore configured to facilitate the path of stones of adequate dimensions for the formation of gabions to the bottom of the hopper, for their extraction to the metal cages. Said hopper is supported by a frame provided with 4 wheels able to roll on a pair of parallel rails. Preferably, the two rear wheels are motorized each by means of a geared motor located in their vicinity. According to one possible variant, only one of the two rear wheels is motorized by means of a geared motor located in its vicinity, the drive of the other rear wheel being effected via a traversing shaft.
Plus précisément, la charpente de la trémie comporte quatre poteaux, chacun étant muni d'une roue à son extrémité inférieure.Specifically, the frame of the hopper has four posts, each having a wheel at its lower end.
De préférence encore, les rails comportent des butées mécaniques d'extrémité, qui permettent de palier un éventuel défaut des moyens de fin de course électriques par ailleurs installés sur le dispositif, qui sont en principe chargés d'arrêter le déplacement de la trémie et de ses extracteurs.More preferably, the rails comprise mechanical end stops, which make it possible to overcome a possible defect of the electrical end-of-stroke means, which are also installed on the device, which are in principle responsible for stopping the movement of the hopper and its extractors.
En pratique les rails sont effectivement munis de contacts, par exemple des contacts de fin de course qui sont reliés électriquement à la commande du ou des motoréducteurs entraînant les roues arrières.In practice, the rails are actually provided with contacts, for example end-of-travel contacts which are electrically connected to the control of the geared motor or motors driving the rear wheels.
De préférence, la trémie est munie de deux extracteurs vibrants munis de moyens de vibrations de type motovibrateurs, ce qui permet d'assurer une couverture optimale de la zone de remplissage, limitant d'une part au maximum l'intervention de l'utilisateur pour la finalisation du remplissage des gabions, et permettant d'autre part d'éviter d'endommager la grille centrale du caisson.Preferably, the hopper is provided with two vibratory extractors equipped with vibratory vibrator-type means, which makes it possible to ensure optimum coverage of the filling zone, limiting on the one hand as much as possible the intervention of the user for the finalization of the filling of the gabions, and on the other hand to avoid damaging the central grid of the box.
En fait, plus précisément, les extracteurs sont placés côte à côte, orientés parallèlement au rail, et présentent une dimension transversalement aux rails de l'ordre de la dimension du caisson dans cette même direction, l'ouverture inférieure de la trémie étant localisée au voisinage de l'une des extrémités des extracteurs dont l'autre extrémité est positionnée par rapport aux rails pour couvrir toute la dimension du caisson parallèlement à la direction des rails au cours du déplacement de la trémie sur lesdits rails.In fact, more specifically, the extractors are placed side by side, oriented parallel to the rail, and have a dimension transversely to the rails of the order of the dimension of the box in the same direction, the lower opening of the hopper being located at adjacent one of the ends of the extractors whose other end is positioned relative to the rails to cover the entire dimension of the box parallel to the direction of the rails during movement of the hopper on said rails.
Les caissons des extracteurs, connus en eux-mêmes, sont composés à titre essentiel de deux parois rigidifiées entre lesquelles est monté un dispositif d'excitation composé de deux motoréducteurs, des traverses entretoises qui portent l'auge de transport des pierres. Des consoles de suspension et des rehausses supérieures munissent en outre les parois en vue d'empêcher la chute des pierres par débordement.The caissons of the extractors, known in themselves, are essentially composed of two rigidified walls between which is mounted an excitation device consisting of two geared motors, cross struts which carry the trough for transporting the stones. Suspension brackets and upper extensions also provide the walls to prevent the stones from falling overflowing.
Le dispositif peut par ailleurs comprendre au moins un variateur de fréquence relié à des moyens de vibrations, par exemple ceux de la table vibrante et/ou ceux des extracteurs, et/ou à au moins un motoréducteur, celui ou ceux qui entraîne(nt) la trémie. En pratique, il comporte de préférence des variateurs de fréquence pour chacun de ces éléments, permettant par exemple de modifier la vitesse de déplacement de la trémie, la vitesse de chargement par modification de la fréquence de vibration des extracteurs ou la vitesse de tassement en procédant de même avec la fréquence de vibration de la table.The device may also comprise at least one frequency converter connected to vibration means, for example those of the vibrating table and / or those of the extractors, and / or to at least one geared motor, the one or those that drive (s) the hopper. In practice, it preferably comprises frequency inverters for each of these elements, for example making it possible to modify the speed of displacement of the hopper, the loading speed by modifying the vibration frequency of the extractors or the speed of settlement by proceeding likewise with the vibration frequency of the table.
De même, de préférence encore, l'invention peut comporter un automate programmable permettant de programmer à l'avance des cycles particuliers, en contrôlant par exemple lesdits variateurs de fréquence pour ajuster les vitesses opérationnelles, ou en ajustant les temporisations qui sont à mettre en place dans la séquence constituant un cycle de remplissage.Likewise, more preferably, the invention may comprise a programmable automaton making it possible to program particular cycles in advance, by controlling, for example, said variable frequency drives to adjust the operating speeds, or by adjusting the delays that are to be set. place in the sequence constituting a filling cycle.
L'invention, cette fois dans le cadre d'un procédé de remplissage de gabions au moyen d'un dispositif tel décrit ci-dessus, peut être mise en oeuvre sous la forme d'un nappage par déplacements de la trémie et des extracteurs selon des allers-retours entre deux positions extrêmes de remplissage de la ou des cages métalliques définissant une distance voisine de la dimension des cages dans la direction du déplacement.The invention, this time in the context of a gabion filling process by means of a device as described above, can be implemented under the form of a layering movement of the hopper and extractors back and forth between two extreme positions of filling of the metal cage or cages defining a distance close to the dimension of the stands in the direction of displacement.
