Description

Domaine technique de l'inventionTechnical field of the invention

L'invention est relative aux moyens d'ancrage pour des fondations d'ouvrage de remontée mécanique, notamment téléporté ou du type téléski.The invention relates to anchoring means for foundations of a mechanical lift structure, in particular a teleported or telescopic type.

État de la techniqueState of the art

Actuellement, la construction d'un ouvrage de remontée mécanique, telle une station de débarquement, une station d'embarquement, ou un pylône de ligne, est généralement longue et peut demander plusieurs mois. En outre, la construction étant effectuée en plein air, celle-ci est soumise aux intempéries qui peuvent retarder le montage de l'ouvrage, notamment pendant la période d'hiver. De manière générale, pour monter l'ouvrage, on creuse une fosse et on réalise un, ou plusieurs, dispositif d'ancrage en béton destiné à porter la partie supérieure de l'ouvrage. Lorsque l'ouvrage est une station, la partie supérieure comprend, entre autre, la poulie d'entraînement du câble de traction transportant les véhicules. Lorsque l'ouvrage est un pylône de ligne, la partie supérieure comprend, entre autre, un balancier à galets.Currently, the construction of a lift, such as a landing station, a boarding station, or a line tower, is usually long and may take several months. In addition, the construction being carried out outdoors, it is subjected to weather that can delay the assembly of the structure, especially during the winter period. In general, to mount the structure, a pit is dug and one or more concrete anchoring device is made to carry the upper part of the structure. When the structure is a station, the upper part comprises, among other things, the traction sheave of the towing cable carrying the vehicles. When the structure is a line pylon, the upper part comprises, inter alia, a pebble beam.

On peut citer la demande de brevet français FR2255200 qui divulgue une station d'un télésiège, comprenant une ossature métallique de suspension d'une poulie. L'ossature métallique comprend deux palées triangulaires ayant chacune deux pieds en fer assemblés en « V » renversé. Les bases des pieds sont fixées à des massifs d'ancrage constitués par des blocs de béton. Les dispositifs d'ancrage en béton sont coulés sur le lieu de montage de la station à l'aide de coffrages. Il est également nécessaire de couler au préalable une dalle en béton, nommée « béton de propreté », sur laquelle les dispositifs d'ancrage sont réalisés. Mais il faut laisser sécher la dalle de béton et les dispositifs d'ancrage pendant un temps assez long, sept jours au minimum, ce qui ralentit la construction de la station. Par ailleurs, le séchage est fortement influencé par les conditions météorologiques, ce qui ralentit encore le procédé de montage de la station.We can quote the French patent application FR2255200 which discloses a station of a chairlift, comprising a metal suspension frame of a pulley. The metal frame includes two triangular piers each having two iron feet assembled in an inverted "V". The bases of the feet are attached to anchor blocks consisting of concrete blocks. Concrete anchors are poured onto the station's assembly site using formwork. It is also necessary to sink preliminary a concrete slab, called "concrete cleanliness", on which the anchoring devices are made. However, the concrete slab and the anchoring devices must be allowed to dry for a long time, at least seven days, which slows the construction of the station. Furthermore, the drying is strongly influenced by the weather conditions, which further slows the process of mounting the station.

Objet de l'inventionObject of the invention

Un objet de l'invention consiste à pallier les inconvénients cités ci-avant, et en particulier à fournir un dispositif d'ancrage pour des fondations d'ouvrage de remontée mécanique qui soit rapide à monter tout en étant suffisamment robuste et qui remplisse les normes de sécurité exigées.An object of the invention is to overcome the drawbacks mentioned above, and in particular to provide an anchoring device for mechanical lift structure foundations which is fast to mount while being sufficiently robust and which meets the standards. required.

Un autre objet de l'invention est de fournir un procédé de fabrication d'un dispositif d'ancrage qui soit rapide à exécuter.Another object of the invention is to provide a method of manufacturing an anchoring device that is quick to perform.

Encore un autre objet de l'invention est de fournir une station et un pylône de ligne d'une remontée mécanique munis d'un tel dispositif d'ancrage.Yet another object of the invention is to provide a station and a line pylon of a ski lift provided with such an anchoring device.

Selon un aspect de l'invention, il est proposé un dispositif d'ancrage pour des fondations d'ouvrage de remontée mécanique, notamment téléporté ou du type téléski, comprenant une embase destinée à être posée sur le sol et une structure métallique reliée mécaniquement à une partie supérieure de l'ouvrage et à l'embase.According to one aspect of the invention, there is provided an anchoring device for foundations of a mechanical lift structure, in particular a teleported or ski lift type, comprising a base intended to be placed on the ground and a metal structure mechanically connected to an upper part of the work and the base.

L'embase comporte au moins un empilement de plaques préfabriquées en béton.The base comprises at least one stack of prefabricated concrete plates.

Ainsi, on fournit un dispositif d'ancrage qui est rapide à monter, et dont les étapes de montage sont moins soumises aux conditions météorologiques. En effet, les plaques préfabriquées en béton peuvent être réalisées en usine et il n'est plus nécessaire de couler les dispositifs d'ancrage sur place. En outre, on n'a plus besoin d'attendre le séchage sur place de l'embase. En particulier, l'étape de préfabrication des plaques peut ne plus être soumise aux intempéries car les plaques sont réalisées dans une zone dédiée à la fabrication des pièces en béton, telle une usine ou un local fermé. On peut en outre obtenir un meilleur contrôle de la fabrication des dispositifs d'ancrage pour garantir une meilleure robustesse à l'ouvrage. Par ailleurs, la réalisation d'un dispositif d'ancrage à l'aide de plaques préfabriquées en béton permet de fournir un dispositif plus facilement transportable de l'usine de fabrication des plaques vers le site de montage de l'ouvrage. Les plaques préfabriquées en béton peuvent être acheminées ensemble, si le transport le permet, ou par paquets ayant chacun un poids inférieur à la limite du transporteur de plaques.Thus, there is provided an anchoring device which is quick to assemble, and whose mounting steps are less subject to weather conditions. Indeed, prefabricated concrete slabs can be made in the factory and it is no longer necessary to cast the anchoring devices on site. In addition, there is no longer a need to wait for the on-site drying of the base. In particular, the prefabrication stage of the plates can no longer be subjected to bad weather because the plates are made in an area dedicated to the manufacture of concrete parts, such as a factory or a closed room. In addition, it is possible to obtain better control over the manufacture of anchoring devices in order to guarantee greater robustness to the structure. Furthermore, the realization of an anchoring device using prefabricated concrete plates makes it possible to provide a more easily transportable device from the plate manufacturing plant to the assembly site of the structure. Prefabricated concrete slabs may be transported together, if transport permits, or in packages each having a weight less than the plate conveyor limit.

Le dispositif peut comporter au moins un moyen de renfort fixé à la structure métallique et configuré pour maintenir en position les plaques préfabriquées en béton d'au moins un empilement.The device may comprise at least one reinforcing means attached to the metal structure and configured to hold in position the prefabricated concrete plates of at least one stack.

Selon un mode de réalisation, chaque moyen de renfort comporte au moins une tige filetée fixée à la structure métallique et traversant les plaques préfabriquées en béton de l'empilement auquel le moyen de renfort est associé.According to one embodiment, each reinforcement means comprises at least one threaded rod fixed to the metal structure and passing through the prefabricated concrete plates of the stack to which the reinforcing means is associated.

Au moins une plaque préfabriquée en béton d'un empilement de l'embase peut comporter un insert taraudé pour fixer au moins une tige filetée à ladite plaque préfabriquée en béton.At least one prefabricated concrete plate of a stack of the base may comprise a threaded insert for fixing at least one threaded rod to said prefabricated concrete plate.

Selon un autre mode de réalisation, chaque moyen de renfort comporte au moins un collier métallique fixé à la structure métallique et entourant les plaques préfabriquées en béton de l'empilement auquel le moyen de renfort est associé.According to another embodiment, each reinforcing means comprises at least one metal collar attached to the metal structure and surrounding the prefabricated concrete plates of the stack to which the reinforcement means is associated.

Les plaques préfabriquées en béton d'un même empilement peuvent être identiques entre elles.
Ainsi on peut fournir des éléments homogènes pour fabriquer les dispositifs d'ancrage, et éviter les dispersions sur la qualité de fabrication des dispositifs.The prefabricated concrete plates of the same stack may be identical to each other.
Thus one can provide homogeneous elements to manufacture the anchoring devices, and avoid dispersions on the manufacturing quality of the devices.

Les plaques préfabriquées en béton de chaque empilement peuvent être identiques entre elles.The prefabricated concrete plates of each stack can be identical to each other.

Selon un autre aspect de l'invention, il est proposé une station de remontée mécanique, comprenant au moins un dispositif d'ancrage tel que définit ci-avant.According to another aspect of the invention, there is provided a lift station, comprising at least one anchoring device as defined above.

Selon encore un autre aspect de l'invention, il est proposé un pylône de ligne de remontée mécanique, comprenant au moins un dispositif d'ancrage tel que définit ci-avant.According to yet another aspect of the invention, there is provided a lift line pylon, comprising at least one anchoring device as defined above.

Selon un autre aspect de l'invention, il est proposé un procédé de fabrication d'un dispositif d'ancrage pour des fondations d'ouvrage de remontée mécanique, notamment téléporté ou du type téléski.According to another aspect of the invention, there is provided a method of manufacturing an anchoring device for foundations of a mechanical lift structure, in particular a teleported or telescopic type.

Le procédé comprend :

  • une étape de préfabrication dans laquelle on réalise une structure métallique et au moins un empilement de plaques préfabriquées en béton ; et
  • une étape de montage du dispositif d'ancrage comprenant une pose de chaque empilement de plaques préfabriquées en béton sur le sol et une fixation de la structure métallique sur chaque empilement de plaques préfabriquées en béton.

The lower part 3 of the station 1 comprises, in turn, at least one anchoring device 10 to support the upper part 2 of the station 1, and comprises at least one pylon 12. Each pylon 12 is mounted between an anchoring device 10 and the frame 5 so as to raise the upper part 2 of the station 1. In the example shown on the figure 1 the station 1 comprises an anchoring device 10 and a pylon 12. According to other embodiments, the station 1 may comprise several anchoring devices on which several pylons are respectively based.

De façon générale, chaque dispositif d'ancrage 10 est posé en un endroit prédéterminé du sol délimitant une zone de montage 14. Le sol peut être situé en montagne ou en ville. Par exemple, la zone de montage 14 peut être intégrée au sein d'un bâtiment ouvert ou fermé. La zone de montage 14 peut comporter une fosse 17 comprenant un ou plusieurs étages. Chaque dispositif d'ancrage 10 peut être posé directement sur l'endroit prédéterminé du sol. Par exemple, chaque dispositif d'ancrage 10 peut être posé directement sur le fond de la fosse 17 qui forme alors la zone de montage 14. Selon un mode de réalisation, l'endroit prédéterminé du sol peut être recouvert en partie par un lit de sable 20, et chaque dispositif d'ancrage 10 est posé sur le lit de sable 20 qui forme la zone de montage 14. On peut aussi envisager de remplacer le lit de sable 20 par une chape réalisée en béton. On peut également réaliser plusieurs chapes en béton, chaque chape en béton étant destinée à recevoir un dispositif d'ancrage 10. Avantageusement, chaque chape en béton est ferraillée. En outre, on peut réaliser, sur la chape en béton, un mortier de scellement liquide formant la zone de montage 14, et on pose chaque dispositif d'ancrage sur le mortier de scellement réalisé. Le mortier de scellement permet d'améliorer le contact physique du dispositif d'ancrage 10 avec la chape en béton. Selon encore un autre mode de réalisation, on peut réaliser une ou plusieurs butées en saillie de la chape en béton, et poser chaque dispositif d'ancrage 10 en appui sur lesdites butées formées. Les butées permettent de maintenir en position chaque dispositif d'ancrage 10 avec la chape en béton. Après avoir posé les dispositif d'ancrages 10 de la station 1, on peut combler la fosse 17 avec un remblai, de terre ou de gravats, jusqu'à un niveau du sol 21, représenté ici en pointillés.In general, each anchoring device 10 is placed at a predetermined location on the ground delimiting a mounting zone 14. The ground may be located in the mountains or in the city. For example, the mounting area 14 may be integrated within an open or closed building. The mounting zone 14 may comprise a pit 17 comprising one or more stages. Each anchoring device 10 can be placed directly on the predetermined location of the ground. For example, each anchoring device 10 can be placed directly on the bottom of the pit 17 which then forms the mounting zone 14. According to one embodiment, the predetermined location of the ground can be covered in part by a bed of 20, and each anchoring device 10 is placed on the sand bed 20 which forms the mounting zone 14. also consider replacing the sand bed 20 with a screed made of concrete. It is also possible to make several concrete screeds, each concrete screed being intended to receive an anchoring device 10. Advantageously, each concrete screed is scraped. In addition, it is possible, on the concrete screed, a liquid sealing mortar forming the mounting zone 14, and each anchoring device is placed on the sealing mortar produced. The sealing mortar makes it possible to improve the physical contact of the anchoring device 10 with the concrete screed. According to yet another embodiment, it is possible to make one or more abutments projecting from the concrete screed, and to place each anchoring device 10 in abutment on said abutments formed. The stops make it possible to hold each anchoring device 10 in position with the concrete screed. After having placed the anchoring devices 10 of the station 1, the pit 17 can be filled with an embankment, earth or rubble, to a level of the ground 21, shown here in dashed lines.

Les différents éléments des dispositifs d'ancrage 10 d'un ouvrage de remontée mécanique sont de préférence réalisés dans une zone de fabrication distincte de la zone de montage 14, c'est-à-dire que la zone de fabrication est située en dehors de la zone de montage 14. Par exemple, la zone de montage 14 peut être située à l'air libre ou non, en montagne ou en ville, et peut être plus ou moins éloignée de la zone de fabrication. La zone de fabrication peut comporter un local particulièrement adapté à la réalisation des pièces du dispositif d'ancrage 10. Par exemple, le local est un local fermé dans lequel les pièces à réaliser ne sont pas soumises aux intempéries.The various elements of the anchoring devices 10 of a mechanical lift structure are preferably made in a manufacturing zone distinct from the mounting zone 14, that is to say that the manufacturing zone is located outside the the mounting zone 14. For example, the mounting zone 14 may be located in the open air or not, in the mountains or in the city, and may be more or less distant from the manufacturing area. The manufacturing zone may include a room that is particularly suitable for producing the parts of the anchoring device 10. For example, the room is a closed room in which the parts to be produced are not subjected to the weather.

Chaque dispositif d'ancrage 10 comprend une embase 25 et une structure métallique 27. L'embase 25 est destinée à être posée sur le sol. La structure métallique 27 est reliée mécaniquement à la partie supérieure 2 de l'ouvrage et à l'embase 25. En particulier, la structure métallique 27 est montée sur l'embase 25 et elle est destinée à recevoir un pylône 12 de l'ouvrage. En particulier, le pylône 12 peut être un pylône de station, comme illustré à la figure 1, ou de ligne. L'embase 25 de chaque dispositif d'ancrage 10, comporte au moins un empilement 28 de plusieurs plaques 29 préfabriquées en béton. Chaque plaque préfabriquée 29 est de préférence réalisée en un seul bloc. En variante, chaque plaque préfabriquée 29 peut comprendre plusieurs plaquettes 40 préfabriquées en béton, telles qu'illustrées sur la figure 4. En particulier un ensemble de plusieurs plaquettes 40 forment une plaque 29 lorsque les plaquettes sont assemblées à un même niveau. Les plaques préfabriquées 29 d'un même empilement 28 sont réalisées séparément, et l'embase 25 du dispositif d'ancrage 10 est réalisée par un assemblage des plaques 29 distinctes précitées. L'assemblage des plaques préfabriquées 29 du dispositif d'ancrage 10 peut être effectué dans la zone de fabrication, ou de préférence dans la zone de montage 14. Par ailleurs, les plaques préfabriquées en béton 29 peuvent être transportées depuis la zone de préfabrication vers la zone de montage 14. On entend ici par transport d'un élément de la station 1, un déplacement de l'élément d'une première zone vers une deuxième zone distincte et dans lequel on conserve l'intégrité de l'élément pour sa réutilisation dans la deuxième zone. L'embase 25 réalisée à l'aide d'un empilement de plaques permet de modifier le positionnement des plaques, et donc de l'embase 25, avant de remplir la fosse 17 de remblai, c'est-à-dire de valider la position correcte du dispositif d'ancrage 10. Au contraire, selon l'art antérieur dans lequel on réalise des dispositifs d'ancrage monobloc en béton en coulant le béton sur place, une fois que le béton est coulé, on ne peut plus modifier avec précision la position du dispositif d'ancrage.Each anchoring device 10 comprises a base 25 and a metal structure 27. The base 25 is intended to be placed on the ground. The metal structure 27 is mechanically connected to the upper part 2 of the structure and to the base 25. In particular, the metal structure 27 is mounted on the base 25 and is intended to receive a pylon 12 of the structure. In particular, the pylon 12 may be a station pylon, as illustrated in FIG. figure 1 , or line. The base 25 of each anchoring device 10 comprises at least one stack 28 of several prefabricated concrete plates 29. Each prefabricated plate 29 is preferably made in one piece. Alternatively, each prefabricated plate 29 may comprise a plurality of prefabricated concrete plates 40, as illustrated in FIG. figure 4 . In particular, a set of several plates 40 form a plate 29 when the plates are assembled at the same level. The prefabricated plates 29 of the same stack 28 are made separately, and the base 25 of the anchoring device 10 is made by an assembly of the aforementioned distinct plates 29. The assembly of the prefabricated plates 29 of the anchoring device 10 can be carried out in the manufacturing zone, or preferably in the mounting zone 14. Moreover, the prefabricated concrete plates 29 can be transported from the prefabrication zone to the mounting zone 14. Here is meant by transporting an element of the station 1, a displacement of the element of a first zone towards a second distinct zone and in which the integrity of the element is preserved for its reuse in the second zone. The base 25 made using a stack of plates makes it possible to modify the positioning of the plates, and therefore of the base 25, before filling the pit 17 of backfill, that is to say, to validate the correct position of the anchoring device 10. On the contrary, according to the prior art in which concrete monobloc anchoring devices are made by casting the concrete on site, once the concrete is poured, it can no longer be modified with accurately the position of the anchoring device.

Chaque dispositif d'ancrage 10 comporte également au moins un moyen de renfort 30 fixé à la structure métallique 27 du dispositif d'ancrage 10. Les moyens de renfort 30 permettent de renforcer le dispositif d'ancrage 10 soumis notamment à la charge de la partie supérieure 2 de l'ouvrage. Plus particulièrement, chaque moyen de renfort 30 d'un dispositif d'ancrage est configuré pour maintenir en position les plaques préfabriquées en béton 29 d'au moins un empilement 28 du dispositif d'ancrage 10.Each anchoring device 10 also comprises at least one reinforcing means 30 fastened to the metal structure 27 of the anchoring device 10. The reinforcing means 30 make it possible to reinforce the anchoring device 10 subjected in particular to the load of the part superior 2 of the work. More particularly, each reinforcing means 30 of an anchoring device is configured to hold in position the prefabricated concrete plates 29 of at least one stack 28 of the anchoring device 10.

Selon un mode de réalisation préféré, chaque moyen de renfort 30 d'un dispositif d'ancrage 10 comporte au moins une tige filetée 31. Chaque tige filetée 31 est fixée à la structure métallique 27 du dispositif d'ancrage 10. En outre, chaque tige filetée 31 traverse les plaques préfabriquées en béton de l'empilement 28 auquel le moyen de renfort 30 est associé. Dans le mode de réalisation préféré, les plaques préfabriquées en béton 29 d'un même empilement 28 sont pourvues d'orifices, non représentés ici à des fins de simplification, pour laisser passer les tiges filetées 31 lors du montage de l'embase 25 du dispositif d'ancrage 10. En effet, dans ce mode de réalisation, les plaques 29 sont préfabriquées en usine avant d'être assemblées pour former l'embase 25 du dispositif d'ancrage 10. Par ailleurs, les plaques préfabriquées en béton 29 peuvent également comprendre des inserts taraudés permettant le passage et la fixation des tiges filetées 31. Lors du montage de l'embase 25, chaque tige filetée 31 traverse les plaques 29 d'un même empilement 28 de sorte que les extrémités de la tige filetée 31 se trouvent à l'extérieur de l'empilement 28. Plus particulièrement, la première extrémité de chaque tige filetée 31 est fixée mécaniquement à la structure métallique 27 du dispositif d'ancrage 10. En outre, la deuxième extrémité de chaque tige filetée 31 peut être tordue, ou bloquée à l'aide d'un écrou de manière à renforcer l'embase 25 du dispositif d'ancrage 10. En particulier, la deuxième extrémité de chaque tige filetée 31 peut être noyée dans le mortier de scellement défini ci-avant.According to a preferred embodiment, each reinforcing means 30 of an anchoring device 10 comprises at least one threaded rod 31. Each threaded rod 31 is fixed to the metal structure 27 of the anchoring device 10. In addition, each threaded rod 31 passes through the prefabricated concrete plates of the stack 28 to which the reinforcement means 30 is associated. In the preferred embodiment, the prefabricated concrete plates 29 of the same stack 28 are provided with orifices, not shown here for the sake of simplification, to allow the threaded rods 31 to pass while the base 25 is being mounted. 10. In fact, in this embodiment, the plates 29 are prefabricated at the factory before being assembled to form the base 25 of the anchoring device 10. Moreover, the prefabricated concrete plates 29 can also include threaded inserts for the passage and fixing of the threaded rods 31. When mounting the base 25, each threaded rod 31 passes through the plates 29 of the same stack 28 so that the ends of the threaded rod 31 is are located outside the stack 28. More particularly, the first end of each threaded rod 31 is mechanically fixed to the metal structure 27 of the anchoring device 10. In addition, the the second end of each threaded rod 31 may be bent, or blocked with a nut so as to strengthen the base 25 of the anchoring device 10. In particular, the second end of each threaded rod 31 may be embedded in the sealing mortar defined above.

La structure métallique 27 d'un dispositif d'ancrage 10 est de préférence modulaire, en d'autres termes, la structure métallique 27 est réalisée à partir de plusieurs pièces distinctes assemblées entre elles lors du montage du dispositif d'ancrage 10 dans la zone de montage 14. Par exemple, chaque structure métallique 27 comprend un socle 32 monté sur un ou plusieurs rails 33, par l'intermédiaire de rivets. Par ailleurs, chaque structure métallique 27 comporte également un système d'ancrage comprenant plusieurs tiges d'ancrage 34. Les tiges d'ancrage 34 sont fixées à une extrémité du socle 32, et permettent de fixer un pylône 12 sur le socle 32. Dans l'exemple illustré à la figure 1, la première extrémité de chaque tige filetée 31 est fixée mécaniquement à l'un des rails 33 de la structure métallique 27 du dispositif d'ancrage 10.The metal structure 27 of an anchoring device 10 is preferably modular, in other words, the metal structure 27 is made from several separate parts assembled together when mounting the anchoring device 10 in the area. 14. For example, each metal structure 27 comprises a base 32 mounted on one or more rails 33, by means of rivets. Furthermore, each metal structure 27 also comprises an anchoring system comprising a plurality of anchoring rods 34. The anchoring rods 34 are fixed to one end of the base 32, and make it possible to fix a pylon 12 on the base 32. the example shown in the figure 1 the first end of each threaded rod 31 is mechanically fastened to one of the rails 33 of the metal structure 27 of the anchoring device 10.

Sur la figure 2, on a représenté de façon schématique un autre mode de réalisation d'un dispositif d'ancrage. Dans cet autre mode de réalisation, chaque moyen de renfort 30 d'un dispositif d'ancrage comporte au moins un collier métallique 35 fixé à la structure métallique 27 du dispositif d'ancrage, par exemple par l'intermédiaire de rivets. Chaque collier 35 entoure les plaques préfabriquées en béton 29 d'un empilement 28 du dispositif d'ancrage 10.On the figure 2 another embodiment of an anchoring device is shown schematically. In this other embodiment, each reinforcing means 30 of an anchoring device comprises at least one metal collar 35 fastened to the metal structure 27 of the anchoring device, for example by means of rivets. Each collar 35 surrounds the prefabricated concrete plates 29 of a stack 28 of the anchoring device 10.

Sur la figure 3, on a représenté de façon schématique encore un autre mode de réalisation d'un dispositif d'ancrage. Dans cet autre mode de réalisation, le dispositif d'ancrage 10 comporte deux empilements 28a et 28b distincts de plaques préfabriquées en béton 29.On the figure 3 another embodiment of an anchoring device is schematically represented. In this other embodiment, the anchoring device 10 comprises two separate stacks 28a and 28b of prefabricated concrete plates 29.

Sur la figure 4, on a représenté de façon schématique les différents éléments d'un dispositif d'ancrage 10 avant le montage de l'embase 25. Sur la figure 5, on a représenté le dispositif d'ancrage 10 décrit à la figure 4, après le montage de l'embase 25.On the figure 4 the various elements of an anchoring device 10 are schematically represented before mounting the base 25. figure 5 the anchoring device 10 described in FIG. figure 4 after the mounting of the base 25.

De façon générale, le montage d'un dispositif d'ancrage comporte une étape de préfabrication dans laquelle on réalise chaque plaque préfabriquée en béton 29 dans la zone de fabrication. Après l'étape de préfabrication, on effectue une étape de transport de chaque plaque préfabriquée en béton 29, depuis la zone de fabrication, vers la zone de montage 14. Par exemple, on transporte les plaques préfabriquées en béton 29 par camion, par hélicoptère, ou tout autre moyen motorisé suffisamment puissant pour soulever et transporter au moins une plaque préfabriquée en béton 29. Puis, après avoir transporté les plaques préfabriquées en béton 29 vers la zone de montage 14, on effectue une étape de montage du dispositif d'ancrage comprenant un montage de l'embase 25 par empilement des plaques préfabriquées en béton 29 sur un endroit prédéterminé du sol délimitant la zone de montage 14. L'étape de montage peut comprendre, avant l'assemblage des plaques préfabriquées, une étape de terrassement dans laquelle on creuse la fosse 17 dans le sol de la zone de montage 14. Après l'étape de terrassement, l'étape de montage peut en outre comprendre un dépôt du lit de sable 20, ou une réalisation d'une chape en béton, avec ou sans mortier de scellement, sur le fond de la fosse 17. Lors de l'étape de montage du dispositif d'ancrage 10, on monte l'embase 25, soit directement sur le sol ou le fond de la fosse 17, soit sur le lit de sable 20 déposé au préalable sur le sol ou le fond de la fosse 17, soit sur la chape en béton.In general, the mounting of an anchoring device comprises a prefabrication step in which each prefabricated concrete plate 29 is produced in the manufacturing zone. After the prefabrication step, a transport step of each prefabricated concrete plate 29 is carried out, from the manufacturing area to the mounting area 14. For example, prefabricated concrete plates 29 are transported by truck, by helicopter, or any other motorized means powerful enough to lift and carry at least one prefabricated concrete plate 29. Then, after having transported the prefabricated concrete plates 29 to the mounting zone 14, a mounting step of the anchoring device comprising a mounting of the base 25 by stacking the prefabricated concrete plates 29 on a predetermined location of the The mounting step may comprise, before assembling the prefabricated plates, a step of excavation in which the pit 17 is dug in the ground of the mounting zone 14. After the step of terracing, the mounting step may further comprise a deposition of the sand bed 20, or an embodiment of a concrete screed, with or without mortar, on the bottom of the pit 17. During the mounting step of the anchoring device 10, the base 25 is mounted, either directly on the ground or the bottom of the pit 17, or on the sand bed 20 previously deposited on the ground or the bottom of the pit 17, either on the concrete screed.

Ainsi, on offre un procédé de montage d'une station de téléphérique robuste et qui dépend moins des conditions météorologiques. En effet, le montage des dispositifs d'ancrage de la station ne nécessite plus de couler du béton sur place. Le montage est également accéléré grâce à l'utilisation de moyens de levage qui ne sont pas nécessairement puissants. Le dispositif d'ancrage de station qui vient d'être décrit donne une possibilité de réutilisation du dispositif d'ancrage lorsqu'on déplace le dispositif d'ancrage dans la station, ou lorsqu'on déplace la station elle-même. L'intégralité de l'ouvrage peut être récupérée en fin de vie de l'installation et être réemployée dans une autre installation, ce qui permet de réduire les empreintes laissées sur site.Thus, there is provided a method of mounting a cable car station robust and less dependent on weather conditions. Indeed, the mounting of the anchoring devices of the station no longer requires pouring concrete on site. The assembly is also accelerated through the use of lifting means that are not necessarily powerful. The station anchoring device just described gives a possibility of reuse of the anchoring device when moving the anchoring device in the station, or when moving the station itself. The entire structure can be recovered at the end of the plant's life and reused in another facility, reducing the footprint left on site.
