Description

La présente invention concerne les abris destinés à protéger les installations d'enneigement automatique et, plus particulièrement, les éléments de ces installations qui sont situés sur le site, et qui réalisent la liaison entre le ou les canons à neige et la ou les conduites servant à les alimenter en eau et, selon le type de canon, en air comprimé.The present invention relates to shelters intended to protect the automatic snowmaking installations and, more particularly, the elements of these installations which are located on the site, and which provide the connection between the snow gun (s) and the pipe (s) serving to supply them with water and, depending on the type of cannon, with compressed air.

Ces abris ont essentiellement pour but de protéger l'appareillage qui permet l'alimentation et le contrôle du ou des canons à neige. Cet appareillage est notamment décrit dans le document FR-A-2 573 854 et un modèle d'abri est décrit dans le document FR-A-2 623 276.The main purpose of these shelters is to protect the equipment that enables the feeding and control of the snow cannon (s). This equipment is notably described in document FR-A-2 573 854 and a shelter model is described in document FR-A-2 623 276.

Ces abris sont disposés tous les 30 à 50 mètres environ, selon les nécessités, et ils peuvent être enterrés dans des tranchées.These shelters are placed every 30 to 50 meters approximately, as necessary, and they can be buried in trenches.

Les abris actuellement utilisés comportent un soubassement en béton qui nécessite des travaux sur site. Ces travaux de maçonnerie sont relativement longs ; dans tous les cas, ils nécessitent le déplacement de matériaux et requièrent une main-d'oeuvre importante.The shelters currently used include a concrete base which requires work on site. These masonry works are relatively long; in all cases, they require the movement of materials and require a large workforce.

La présente invention a pour but de simplifier la mise en oeuvre sur le terrain par une utilisation d'ensembles finis, légers, qui suppriment toute maçonnerie sur sites.The present invention aims to simplify the implementation in the field by the use of finished sets, light, which remove all masonry on sites.

L'invention a encore pour but de standardiser ce type d'abri et de le rendre conforme aux principales exigences en matière de dimension, d'isolation thermique, de solidité et d'étanchéité. L'abri selon l'invention permet également de laisser sur site, en permanence, la vanne d'alimentation du canon à neige.Another object of the invention is to standardize this type of shelter and to make it conform to the main requirements in terms of size, thermal insulation, solidity and sealing. The shelter according to the invention also makes it possible to leave the snow gun supply valve permanently on site.

L'abri selon l'invention se présente sous la forme d'un caisson monobloc préfabriqué renfermant les appareillages de connexion et de contrôle de l'alimentation du canon ; cet abri est directement posé sur au moins une conduite et il comporte d'une part, sur son fond, au moins une rainure qui permet de le caler sur ladite conduite et, d'autre part, des moyens d'ancrage pour des organes de liaison coopérant avec ladite conduite.The shelter according to the invention is in the form of a prefabricated monobloc box containing the connection and control equipment for the cannon supply; this shelter is placed directly on at least one pipe and it comprises on the one hand, on its bottom, at least one groove which makes it possible to wedge it on said pipe and, on the other hand, anchoring means for connecting members cooperating with said pipe.

Selon une disposition préférentielle de l'invention, les organes d'arrimage sont constitués de sangles qui permettent la réalisation d'une liaison rapide et durable entre l'abri et au moins une conduite d'alimentation ; ces sangles sont fixées sur l'abri au moyen de boucles aménagées à la périphérie inférieure dudit abri.According to a preferred arrangement of the invention, the securing members are made up of straps which allow a quick and lasting connection to be made between the shelter and at least one supply pipe; these straps are fixed to the shelter by means of loops arranged at the lower periphery of said shelter.

L'abri selon l'invention est réalisé en matériau plastique du genre polyéthylène, obtenu par rotomoulage.The shelter according to the invention is made of plastic material of the polyethylene type, obtained by rotational molding.

Cet abri comporte des renforts disposés à sa partie supérieure et à sa partie inférieure, en forme de ceinture, reliés par boulonnage à une structure interne qui sert au positionnement des différents organes enfermés dans l'abri, ainsi qu'au renforcement dudit abri.This shelter comprises reinforcements arranged at its upper part and at its lower part, in the form of a belt, connected by bolting to an internal structure which is used for positioning the various organs enclosed in the shelter, as well as for strengthening said shelter.

L'utilisation d'un matériau comme le polyéthylène permet notamment une adaptation de l'abri sur le site et en particulier un perçage plus commode des orifices nécessaires, d'une part, au raccordement sur les conduites d'alimentation et, d'autre part, au passage des câbles de puissance et de dialogue.The use of a material such as polyethylene allows in particular an adaptation of the shelter on the site and in particular a more convenient drilling of the orifices necessary, on the one hand, for connection on the supply pipes and, on the other hand hand, the passage of the power and dialogue cables.

L'abri selon l'invention comporte encore, à sa partie supérieure, un renfort en forme de bossage, pour le passage d'au moins une perche de soutènement de canon à neige. Cette perche comporte des moyens d'ancrage sur les rails internes, lesquels moyens permettent sa fixation dans une position verticale quelque soit l'inclinaison de l'abri lorsqu'il est fixé sur la ou les conduites d'alimentation.The shelter according to the invention also comprises, at its upper part, a boss-shaped reinforcement, for the passage of at least one snow cannon support pole. This pole comprises means for anchoring to the internal rails, which means allow it to be fixed in a vertical position whatever the inclination of the shelter when it is fixed to the supply pipe or pipes.

L'abri selon l'invention comporte encore un trou d'homme obturé par un couvercle muni de charnières du type en câble revêtu d'un matériau genre nylon, pour simplifier le montage et surtout le rendre plus fiable.The shelter according to the invention also comprises a manhole closed by a cover provided with hinges of the cable type coated with a nylon-like material, to simplify assembly and above all to make it more reliable.

Afin d'éviter l'intrusion dans l'abri, le couvercle peut être muni d'une serrure inviolable.To avoid intrusion into the shelter, the cover can be fitted with a tamper-proof lock.

L'invention sera encore illustrée, sans être aucunement limitée, par la description suivante d'un mode de réalisation particulier donné à titre d'exemple et représenté sur les dessins annexés, dans lesquels :

  • la figure 1 est une vue générale schématique de face, d'un abri selon l'invention, positionné sur des conduites,dans une tranchée ;
  • la figure 2 est une vue de côté, en coupe, de l'abri selon l'invention ;
  • la figure 3 est une vue de dessus de l'abri seul ;
  • la figure 4 représente la ceinture disposée à la partie inférieure de l'abri, servant notamment à l'ancrage de ce dernier sur les conduites d'air et d'eau.
The invention will be further illustrated, without being in any way limited, by the following description of a particular embodiment given by way of example and represented in the appended drawings, in which:
  • Figure 1 is a general schematic front view of a shelter according to the invention, positioned on pipes, in a trench;
  • Figure 2 is a side view, in section, of the shelter according to the invention;
  • Figure 3 is a top view of the shelter alone;
  • Figure 4 shows the belt disposed at the lower part of the shelter, used in particular for anchoring the latter on the air and water pipes.

Tel que représenté sur les figures, l'abri se présente sous la forme d'un parallélépipède réalisé en matériau plastique du genre polyéthylène, moulé par rotomoulage. L'encombrement de ce parallélépipède est voisin de celui d'un cube d'un volume de l'ordre de 1 m³. Un abri de ce type doit pouvoir supporter sans dommage des températures allant de -25°C à + 40°C.As shown in the figures, the shelter is in the form of a parallelepiped made of plastic material of the polyethylene type, molded by rotational molding. The size of this parallelepiped is close to that of a cube with a volume of the order of 1 m³. A shelter of this type must be able to withstand temperatures from -25 ° C to + 40 ° C without damage.

Cet abri comporte, d'une manière générale, des dépouilles de démoulage, des arrondis de renforcements, des rayons minimum et limitation des prises en gel liés au procédé de fabrication.This shelter generally comprises mold release spheres, rounded reinforcements, minimum radii and limitation of gel catches linked to the manufacturing process.

Cet abri est notamment constitué d'un plancher ou fond 1 qui comporte des logements servant à le positionner sur la ou les tuyauteries bordant la piste. Ce fond 1 comporte des rainures longitudinales formant un logement central 2 pour la tuyauterie d'eau 3 et deux logements latéraux 4 et 5 pour la tuyauterie d'air 6 qui peut se situer d'un côté ou de l'autre de la tuyauterie d'eau selon le cas, alternée éventuellement avec un drain principal 6' d'eau de vidange.This shelter is in particular constituted by a floor or bottom 1 which comprises housings used to position it on the pipe or pipes bordering the track. This bottom 1 has longitudinal grooves forming a central housing 2 for the water piping 3 and two lateral housings 4 and 5 for the air piping 6 which can be located on one side or the other of the piping d 'water as appropriate, alternately optionally with a main drain 6' of drain water.

Le logement 2 consiste en une rainure qui s'étend sur toute la longueur du fond 1 ; cette rainure a une section trapézoïdale qui permet de caler le fond 1 sur la conduite 3. Les logements 4 et 5 consistent en des rainures aménagées dans les angles inférieurs de l'abri, entre le fond 1 et les parois latérales 7 et 8 ; le fond de ces logements en rainures se situe sensiblement dans un même plan.The housing 2 consists of a groove which extends over the entire length of the bottom 1; this groove has a trapezoidal section which makes it possible to wedge the bottom 1 on the pipe 3. The housings 4 and 5 consist of grooves arranged in the lower corners of the shelter, between the bottom 1 and the side walls 7 and 8; the bottom of these grooved housings is located substantially in the same plane.

On remarque, à la partie inférieure de ces parois latérales 7 et 8, au-dessus des logements 4 et 5, une ceinture 9, métallique, représentée en détail figure 4. Cette ceinture 9 est réalisée en deux parties égales et symétriques ; elle renforce la partie inférieure de l'abri et elle est disposée dans un décrochement 10 aménagé à la partie inférieure des quatre côtés de l'abri.We notice, at the bottom of these walls lateral 7 and 8, above the housings 4 and 5, a metal belt 9, shown in detail in FIG. 4. This belt 9 is produced in two equal and symmetrical parts; it reinforces the lower part of the shelter and it is arranged in a recess 10 arranged in the lower part of the four sides of the shelter.

Cette ceinture 9 est doublée, intérieurement, au moyen de rails 11 positionnés à l'intérieur de l'abri ; la solidarisation de la ceinture 9 sur les rails 11 s'effectue par boulons ou rivets.This belt 9 is doubled, internally, by means of rails 11 positioned inside the shelter; the belt 9 is secured to the rails 11 by bolts or rivets.

La ceinture 9, figures 1 et 4, a une section en U ouvert sur l'extérieur. On remarque des boucles 12 soudées entre les ailes supérieures et inférieures de la ceinture 9. Ces boucles 12 servent d'ancrage aux sangles 13 et 14, représentées figures 1 et 2, qui assurent le serrage et la fixation de l'abri sur les conduites 3 et 6.The belt 9, Figures 1 and 4, has a U-shaped section open to the outside. Note loops 12 welded between the upper and lower wings of the belt 9. These loops 12 serve to anchor the straps 13 and 14, shown in Figures 1 and 2, which tighten and secure the shelter on the pipes 3 and 6.

Les boucles 12 sont en forme de tige métallique conformée en trapèze ; elles sont fixées sur les faces avant et arrière de la ceinture 9 c'est-à-dire sur les faces qui se situent au-dessus des conduites 3, 6 et 6'. A noter que l'abri peut être fixé sur la seule conduite d'eau 3 en l'absence de conduite d'air. Le réglage de l'assiette se fera par un calage entre le fond et le sol.The loops 12 are in the form of a metal rod shaped as a trapezoid; they are fixed on the front and rear faces of the belt 9, that is to say on the faces which are located above the pipes 3, 6 and 6 ′. Note that the shelter can be fixed on the only water pipe 3 in the absence of an air pipe. The adjustment of the attitude will be done by wedging between the bottom and the ground.

L'abri comporte également, à sa partie supérieure, logée dans un décrochement 15 identique au décrochement inférieur 10, une deuxième ceinture 16 à section en U, doublée intérieurement par des rails 17 ; ces rails 17 sont également fixés, à travers les parois de l'abri, au moyen de boulons ou rivets. Cette ceinture 16 se situe dans un plan parallèle au plan de la ceinture inférieure 9. La ceinture supérieure 16 est réalisée également en deux parties égales et symétriques.The shelter also comprises, at its upper part, housed in a recess 15 identical to the lower recess 10, a second belt 16 with a U-section, internally doubled by rails 17; these rails 17 are also fixed, through the walls of the shelter, by means of bolts or rivets. This belt 16 is located in a plane parallel to the plane of the lower belt 9. The upper belt 16 is also produced in two equal and symmetrical parts.

Les rails internes 11 et 17 ont une section en U à bords refermés. Ces rails 11 et 17 permettent notamment de fixer l'appareillage et, en particulier, comme représenté figure 1, le fourreau 18 qui sert de soutien et de guidage à la perche 19 à l'extrémité de laquelle est fixé un canon à neige 20. Cette perche est verrouillée
sur le fourreau par tout moyen approprié. Le fourreau 18 est ancré à son extrémité inférieure sur le rail interne 11, au moyen d'un boulon 21 dont la tête est bloquée dans le rail 11. On remarque, à la partie supérieure du fourreau, figures 1 et 2 et dans l'encadré de la figure 1, un plat 22 soudé latéralement, et muni d'une lumière 23 qui permet le passage d'un boulon 24 dont la tête est prisonnière du rail supérieur intérieur 17. L'inclinaison du fourreau 18 peut être réglée, grâce à la lumière 23, pour permettre un positionnement vertical de la perche 19 quelle que soit la pente des conduites d'eau et d'air. Le montage du fourreau 18 sur les rails 11 et 17, en coopération avec les ceintures 9 et 16, lui procure une bonne résistance mécanique, nécessaire compte-tenu des efforts et réactions engendrés par le canon 20 et par les effets du vent, de la neige et de la glace.The internal rails 11 and 17 have a U-shaped section with closed edges. These rails 11 and 17 allow in particular to fix the apparatus and, in particular, as shown in FIG. 1, the sheath 18 which serves to support and guide the pole 19 at the end of which is fixed a snow cannon 20. This pole is locked
on the scabbard by any appropriate means. The sleeve 18 is anchored at its lower end to the internal rail 11, by means of a bolt 21, the head of which is locked in the rail 11. We note, in the upper part of the sleeve, Figures 1 and 2 and in the framed in Figure 1, a flat 22 welded laterally, and provided with a light 23 which allows the passage of a bolt 24 whose head is trapped in the inner top rail 17. The inclination of the sheath 18 can be adjusted, thanks to the light 23, to allow vertical positioning of the pole 19 regardless of the slope of the water and air pipes. The mounting of the sheath 18 on the rails 11 and 17, in cooperation with the belts 9 and 16, gives it good mechanical resistance, necessary in view of the forces and reactions generated by the barrel 20 and by the effects of the wind, the snow and ice.

On peut positionner, selon les besoins, sur un même abri, deux canons à neige 20 soutenus, de part et d'autre de l'abri, par des fourreaux 18 fixés latéralement au moyen de rails internes 11 et 17.Two snow cannons 20 supported, on either side of the shelter, by sleeves 18 fixed laterally by means of internal rails 11 and 17 can be positioned, as required, on the same shelter.

La perche 19 traverse le plafond 25 de l'abri dans une zone renforcée par un bossage 26. Ce bossage 26 s'étend transversalement sur tout le plafond 25. Il comporte, figure 3, de chaque côté de son plat supérieur 27, des amorces d'orifices 28 destinées au passage des perches 19 de soutènement des canons à neige.The pole 19 crosses the ceiling 25 of the shelter in an area reinforced by a boss 26. This boss 26 extends transversely over the entire ceiling 25. It has, in Figure 3, on each side of its upper plate 27, primers orifices 28 intended for the passage of the poles 19 for supporting the snow cannons.

Le plafond 25 comporte encore des orifices 29 pour le passage des tuyauteries flexibles 30 servant à l'alimentation du ou des canons. Un joint en forme de rondelle souple est interposé entre le plafond 25 et la tuyauterie 30. Ces orifices 29 se situent sensiblement au centre du plafond 25, disposés sur une même ligne transversale.The ceiling 25 also has orifices 29 for the passage of flexible pipes 30 used to supply the gun (s). A joint in the form of a flexible washer is interposed between the ceiling 25 and the piping 30. These orifices 29 are located substantially in the center of the ceiling 25, arranged on the same transverse line.

Le plafond 25 comporte encore un trou d'homme 31, pour permettre l'accès à l'intérieur de l'abri, en vue de réaliser le montage des différents composants ainsi que leur branchement. Ce trou d'homme 31 est recouvert par un couvercle 32. Ce couvercle 32 est relié à la paroi
latérale du trou d'homme au moyen d'un câble 33 revêtu de plastique, formant une sorte de laçage de façon à éviter les inconvénients classiques des charnières métalliques.The ceiling 25 also has a manhole 31, to allow access to the interior of the shelter, in order to assemble the various components as well as their connection. This manhole 31 is covered by a cover 32. This cover 32 is connected to the wall
lateral of the manhole by means of a cable 33 coated with plastic, forming a sort of lacing so as to avoid the conventional drawbacks of metal hinges.

On a représenté, figure 2, des boîtiers 34, 35 de branchements électriques, ainsi que la vanne 36 qui commmande l'alimentation du canon à neige 20.FIG. 2 shows boxes 34, 35 of electrical connections, as well as the valve 36 which controls the supply of the snow cannon 20.

La vanne 36 est connectée aux conduites d'air 6 et d'eau 3 par des manchettes de piquage 38 et 39. Ces manchettes de piquage traversent le fond 1 de l'abri. De préférence, le trou de la manchette d'eau 38 est réalisé avant le montage de l'abri sur les conduites ; le trou de la manchette de piquage d'air 39 est réalisé de préférence sur le site.The valve 36 is connected to the air 6 and water 3 pipes by tapping cuffs 38 and 39. These tapping cuffs pass through the bottom 1 of the shelter. Preferably, the hole in the water cuff 38 is made before mounting the shelter on the pipes; the hole in the air connection sleeve 39 is preferably made on site.

De la même façon, des orifices 40 disposés dans le fond de l'abri, pour sa vidange, sont réalisés sur site, et ces orifices 40 sont reliés au drain principal 6' par des tuyauteries souples.Similarly, orifices 40 arranged in the bottom of the shelter, for emptying, are made on site, and these orifices 40 are connected to the main drain 6 'by flexible pipes.

On remarque encore, disposés sensiblement à mi-hauteur de l'abri, dans les angles, des manchons cylindriques 41. Ces manchons cylindriques 41 permettent, par exemple, le passage des câbles de liaison 42 des différents branchements électriques de l'abri avec les réseaux électriques de la piste.We also note, arranged substantially at mid-height of the shelter, in the corners, cylindrical sleeves 41. These cylindrical sleeves 41 allow, for example, the passage of the connecting cables 42 of the various electrical connections of the shelter with the track electrical networks.

L'assemblage de l'abri sur les conduites 3 et 6 s'effectue très rapidement au moyen des sangles 13, 14 et d'un simple outil tenseur de cerclage. Les sangles sont de préférence réalisées en fibres polyester.The assembly of the shelter on the pipes 3 and 6 is carried out very quickly by means of the straps 13, 14 and a simple strapping tensioning tool. The straps are preferably made of polyester fibers.

Les différents branchements ou connections s'effectuent également rapidement, soit par des orifices déjà prévus, soit par des prévisions d'orifices ou même par un découpage de la paroi de l'abri réalisé à cette fin en un matériau plastique facilement découpable.The various connections or connections are also made quickly, either by orifices already provided, or by provision of orifices or even by cutting the wall of the shelter made for this purpose from an easily cut plastic material.

La structure de l'abri, de forme sensiblement cubique, munie de ceintures 9 et 16 en forme de frette, permet également de résister à de fortes sollicitations extérieures comme des poussées de terre. Les endommagements accidentels occasionnés par le passage de chenillettes ou engins de damage sur la partie supérieure de l'abri peuvent être éliminés par la pose d'un nouveau capot supérieur emboîté et riveté sur la structure monobloc existante. Par ailleurs, un tel abri peut être réalisé aisément dans une teinte qui permet son intégration dans le paysage, c'est-à-dire une teinte verdoyante ou de couleur roche par exemple.The structure of the shelter, of substantially cubic shape, provided with belts 9 and 16 in the form of a hoop, also makes it possible to withstand strong external stresses such as earth thrusts. Accidental damage caused by the passage of caterpillars or tamping machines on the upper part of the shelter can be eliminated by installing a new upper cover fitted and riveted on the existing monobloc structure. Furthermore, such a shelter can be easily produced in a shade which allows its integration into the landscape, that is to say a verdant shade or rock color for example.
