Description

Dispositif de déclenchement d'avalanches  Avalanche triggering device
La présente invention concerne un dispositif de déclenchement d'avalanches et notamment d'avalanches de neige. The present invention relates to a device for triggering avalanches and in particular avalanches of snow.
Un tel dispositif est utilisé pour déclencher préventivement des avalanches dans des emplacements où l'accumulation de neige pourrait entraîner des risques d'avalanches importants mettant en péril des biens ou des personnes, notamment en liaison avec l'existence d'infrastructures de transport, de domaines skiables ou de zones habitées.  Such a device is used to preventively trigger avalanches in locations where the accumulation of snow could lead to major avalanche risks endangering property or people, particularly in connection with the existence of transport infrastructure, ski areas or inhabited areas.
Des dispositifs et des techniques pour déclencher de façon volontaire des avalanches sont déjà connus.  Devices and techniques for voluntarily triggering avalanches are already known.
Une première technique consite en un dépôt de charges explosives par un opérateur à l'endroit précis où l'on veut déclencher l'avalanche. Ce dépôt peut se faire soit à partir d'un hélicoptère par lancer, soit à partir du sol, la charge pouvant être alors déposée ou lancée à l'endroit adéquat. L'amorçage de la charge, dans les deux cas, est généralement obtenue par mèche lente ou électriquement.  A first technique consits in a deposit of explosive charges by an operator at the precise place where we want to trigger the avalanche. This deposit can be made either from a helicopter by launching or from the ground, the load can then be deposited or launched at the appropriate place. The charging of the charge, in both cases, is generally obtained by slow wick or electrically.
Les risques inhérents à cette technique sont importants. En plus des risques directement liés à la manipulation d'explosifs, l'opérateur doit, pour les dépôts au sol , se rendre dans des zones souvent escarpées dont le manteau neigeux est instable. Ces interventions doivent parfois se faire, en outre, que ce soit pour les dépôts au sol ou héliportés, dans des conditions climatiques délicates.  The risks inherent in this technique are important. In addition to the risks directly related to the handling of explosives, the operator must, for deposits on the ground, go to often steep areas whose snowpack is unstable. These interventions must sometimes be done, in addition, whether for deposits on the ground or helicopter, in difficult weather conditions.
Pour réduire ces risques liés au déplacement sur la zone de tir, des techniques de déclenchement à distance ont été mises en place.  To reduce these risks related to movement on the firing zone, remote triggering techniques have been implemented.
Des techniques de déclenchement à distance utilisent des armes militaires telles que des lance-roquettes ou des lanceurs d'obus pour provoquer l'explosion sur site. Ce type de dispositif n'est pas adapté à certaines législations, comme la législation française, qui interdisent le stockage de charges amorcées.  Remote triggering techniques use military weapons such as rocket launchers or shells to cause an onsite explosion. This type of device is not adapted to certain laws, such as French law, which prohibit the storage of charges initiated.
Le dispositif connu sous la dénomination commerciale CATEX utilise un système de câble transporteur d'explosifs passant au dessus d'un ou plusieurs couloirs d'avalanches. Ce type de solution s'il permet de limiter les risques liés au déplacement sur les lieux du déclenchement de l'avalanche n'apporte aucune solution concernant la manipulation et le stockage d'explosifs. Ce dispositif nécessite, de plus, l'installation onéreuse d'un système de pylônes supportant le câble transporteur, ceci sur des distances qui peuvent être très grandes. The device known under the trade name CATEX uses an explosive conveying cable system passing over one or more avalanche corridors. This type of solution, if it makes it possible to limit the risks associated with the movement on the scene of the triggering of the avalanche, provides no solution concerning the handling and storage of explosives. This device requires, moreover, the expensive installation of a system of pylons supporting the carrier cable, this over distances that can be very large.
Une voie pour réduire les risques liés à la manipulation des explosifs est l'emploi de gaz explosifs pour générer une onde de choc servant à déclencher l'avalanche.  One way to reduce the risks associated with the handling of explosives is the use of explosive gases to generate a shock wave to trigger the avalanche.
Selon ce principe sont connus des dispositifs transportables qui peuvent être amenés sur site par hélitreuillage. Ces dispositifs, décrits dans les documents WO 2007/096524 et WO 2009/080977, utilisent tous deux un mélange de gaz explosifs afin de déclencher une explosion au-dessus du manteau neigeux. Ces dispositifs possèdent le principal avantage de pouvoir être util isés sur des zones non préalablement équipées et ceci sans aucune manipulation d'explosif. Les inconvénients restent ceux inhérents à l'utilisation de l'hél icoptère, à savoir les coûts d'exploitation qui restent importants et l'impossibilité d'intervenir par mauvais temps.  According to this principle are known transportable devices that can be brought on site by hoist. These devices, described in WO 2007/096524 and WO 2009/080977, both use a mixture of explosive gases to trigger an explosion above the snowpack. These devices have the main advantage of being usable on previously unprepared areas and this without any manipulation of explosive. The disadvantages remain those inherent to the use of the helicopter, namely the operating costs which remain important and the impossibility of intervening in bad weather.
Un autre type de dispositif est celui connu sous la dénomination Another type of device is the one known under the name
GAZ EX. Ce type d e d ispos itif, décrit d a ns l e docu ment F R 2 636 729, comprend un tube exploseur à fond fermé monté sur un support en béton et dont l'ouverture est dirigée en direction du manteau neigeux. L'inclinaison et le maintien du tube sont obtenus au moyen de deux pieds porteurs. Ces deux pieds, selon qu'il s'agit d'un dispositif de type statique ou à inertie, sont soit fixés sur un bloc d'ancrage, soit munis d'un contre-poids qui repose sur une plateforme bétonnée. Un circuit de gaz est utilisé pour remplir le tube exploseur de gaz comburant et de gaz carburant qu'un dispositif d'allumage, avantageusement monté à l'arrière du tube exploseur, permet d'allumer. Le souffle de l'explosion qui en résulte est alors dirigé, par l'ouverture du tube, en direction du manteau neigeux déclenchant ainsi l'avalanche. Ce type de dispositif comprend une réserve de gaz suffisante pour une saison et un système de mise à feux commandé à distance, qui lui permettent d'obtenir, entre autres avantages, une complète autonomie et d'offrir une sécurité parfaite pour l'opérateur. L'installation fixe de ce dispositif permet, en outre, de garantir une puissance suffisante et pérenne pour la protection de couloirs d'avalanches de tailles importantes. Le principal inconvénient lié à ce type de dispositif est les coûts d'installation liés à la réalisation du support fixant la base du canon et du bloc d'ancrage ou de la plateforme béton, en fonction du type de dispositif, qui soutient les pieds porteurs. Afin de remédier aux inconvénients précités, l'invention concerne un dispositif de déclenchement d'avalanches, comportant un tube dont une extrém ité fermée est montée sur un support lu i-même fixé à flanc de montagne, par exemple sur un massif béton, et dont l'autre extrémité ouverte est tournée vers le manteau neigeux, le dispositif comportant en outre un moyen de remplissage du tube par un mélange gazeux explosif et un moyen d'amorçage déclenchant l'explosion dudit mélange, caractérisé en ce qu'il comporte au moins deux poutres qui, fixées chacune par une de ses extrémités au support, s'étendent le long du tube parallèlement à celui-ci pour en assurer le support, tout en formant un moyen d'amortissement du déplacement du tube consécutivement à l'explosion du mélange gazeux. EX GAS This type of ispos itif, described in document FR 2 636 729, comprises a closed bottom exploded tube mounted on a concrete support and whose opening is directed towards the snowpack. The inclination and the maintenance of the tube are obtained by means of two supporting feet. These two feet, depending on whether it is a static type device or inertia, are either fixed on an anchor block or provided with a counterweight that rests on a concrete platform. A gas circuit is used to fill the exploding tube with oxidizing gas and fuel gas which an ignition device, advantageously mounted at the rear of the exploder tube, allows to ignite. The resulting blast of the explosion is then directed, through the opening of the tube, towards the snowpack triggering the avalanche. This type of device includes a reserve of sufficient gas for a season and a remote ignition system, which allows it to obtain, among other advantages, a complete autonomy and to offer a perfect safety for the operator. The fixed installation of this device also makes it possible to guarantee sufficient and lasting power for the protection of large avalanche corridors. The main disadvantage related to this type of device is the installation costs related to the realization of the support fixing the base of the barrel and the anchor block or the concrete platform, depending on the type of device, which supports the bearing feet . In order to overcome the aforementioned drawbacks, the invention relates to an avalanche triggering device, comprising a tube of which a closed end is mounted on a support lu itself fixed to the side of a mountain, for example on a concrete block, and whose other open end is turned towards the snowpack, the device further comprising means for filling the tube with an explosive gaseous mixture and a means of initiation triggering the explosion of said mixture, characterized in that it comprises at least two beams which, each fixed by one of its ends to the support, extend along the tube parallel to the latter to provide support, while forming a damping means of the displacement of the tube following the explosion gaseous mixture.
Ainsi, les poutres supportant le tube exploseur suppriment avantageusement la nécessité de pieds porteurs et donc de tous dispositifs, tels que des blocs d'ancrages, nécessaires pour les supporter réduisant alors les coût d'installation de ce dispositif. L'invention permet en outre, de par le moyen amortissement offert par les poutres, de réduire les contraintes transmises au support lors de chaque déclenchement d'avalanche pérénisant ainsi l'installation du dispositif.  Thus, the beams supporting the exploding tube advantageously remove the need for support feet and therefore all devices, such as anchor blocks, necessary to support reducing the cost of installation of this device. The invention also makes it possible, by means of the damping provided by the beams, to reduce the stresses transmitted to the support during each avalanche release, thereby perpetuating the installation of the device.
Selon une possibilité de l'invention, les poutres sont disposées parallèlement de part et d'autre du tube.  According to a possibility of the invention, the beams are arranged parallel on either side of the tube.
Une telle disposition permet ainsi de répartir symétriquement les contraintes lors du déclenchement de l'avalanche et de limiter les mouvements latéraux du tube exploseur et donc les efforts exercés sur les moyens de fixation entre le tube et le support.  Such an arrangement thus makes it possible to distribute the stresses symmetrically during the triggering of the avalanche and to limit the lateral movements of the exploder tube and therefore the forces exerted on the fastening means between the tube and the support.
Préférentiel lement les poutres sont solidarisées les unes aux autres.  Preferentially the beams are joined to each other.
La solidarisation produit une meilleure répartition des efforts lors du déplacement engendré par l'explosion au sein du tube exploseur et permet ainsi de réduire les efforts exercés lors du déclenchement d'une avalanche sur les moyens de fixation du tube exploseur sur le support.  The fastening produces a better distribution of forces during the displacement caused by the explosion within the exploder tube and thus reduces the forces exerted during the triggering of an avalanche on the attachment means of the exploder tube on the support.
Avantageusement les poutres sont pleines et de section rectangulaire avec, vue en coupe transversale, la longueur située verticalement et la largeur horizontalement.  Advantageously, the beams are solid and of rectangular section with cross-sectional view, the length located vertically and the width horizontally.
Le choix de cette forme permet une meilleure répartition des efforts lors du déplacement. En effet l'explosion au sein du tube ayant, de par le principe de l'invention, tendance à créer une poussé verticale, les poutres doivent offrir une plus grande résistance dans cette direction. The choice of this shape allows a better distribution of the forces during the displacement. Indeed the explosion within the tube having, by the principle of the invention, tend to create a vertical push, the beams must offer greater resistance in this direction.
Préférentiellement, le rapport entre la longueur et la largeur est de l'ordre de quatre.  Preferably, the ratio between the length and the width is of the order of four.
Selon une des caractéristiques de l'invention, chaque poutre est réalisée à partir d'un matériau possédant un module d'Young compris dans une plage de 60 GPa et de 250 GPa, et préférentiellement de l'ordre de 150 GPa à 200 GPa et possédant une résilience conservée pour des températures entre +40 °C et -40 °C.  According to one of the features of the invention, each beam is made from a material having a Young's modulus in a range of 60 GPa and 250 GPa, and preferably of the order of 150 GPa to 200 GPa and having a resilience preserved for temperatures between +40 ° C and -40 ° C.
De cette manière, chaque poutre est à même de ce déformer afin d'accompagner et d'amortir le mouvement du tube exploseur par rapport au support ceci dans les conditions de températures de fonctionnement extrêmes du dispositif.  In this way, each beam is able to deform in order to accompany and dampen the movement of the exploder tube relative to the support this in the extreme operating temperature conditions of the device.
Selon une des caractéristique de l'invention, chaque poutre est réalisée à partir d'acier à haute limite d'élasticité.  According to one of the features of the invention, each beam is made from high yield strength steel.
L'utilisation de l'acier à haute limite d'élasticité offre à la fois les qualités de solidité et d'élasticité nécessaires pour garantir l'amortissement des mouvements du tube exploseur après le déclenchement d'une avalanche.  The use of high yield strength steel offers both the qualities of strength and elasticity necessary to guarantee the damping of the movements of the exploding tube after the triggering of an avalanche.
Selon un mode de réalisation du dispositif, chaque poutre est constituée d'une pluralité d'éléments solidarisés les uns aux autres.  According to one embodiment of the device, each beam consists of a plurality of elements secured to each other.
L'emploi de pl usieurs éléments permet ainsi, pour un effet amortissant donné, de réduire le poids du dispositif  The use of several elements thus makes it possible, for a given damping effect, to reduce the weight of the device
Avantageusement, le tube est monté articulé du coté de son fond sur un axe horizontal perpendiculaire à l'axe du tube, tandis que sa partie avant est montée, au moyen d'une liaison mobile, à proximité des extrémités avant des poutres.  Advantageously, the tube is hinged on the side of its bottom on a horizontal axis perpendicular to the axis of the tube, while its front portion is mounted by means of a movable connection, near the front ends of the beams.
Ainsi le montage du tube exploseur sur le support n'entrave pas le déplacement du tube pendant le déclenchement d'avalanche et permet donc aux poutres d'assurer leur fonction d'amortissement. Le montage mobile entre les poutres et le tube, quant à lui, permet à la fonction de support des poutres de ne pas gêner leur fonction d'amortissement.  Thus mounting the exploder tube on the support does not hinder the movement of the tube during avalanche triggering and thus allows the beams to ensure their damping function. The movable mounting between the beams and the tube, meanwhile, allows the support function of the beams not to interfere with their damping function.
Selon une caractéristique de l'invention, chaque poutre comporte à proximité de son extrémité libre un doigt qui, tourné du coté de l'autre poutre, est destiné à être engagé dans une chape solidaire au tube, dont l'ouverture est tournée du coté du fond du tube. De cette manière, le doigt présent sur les poutres, coulissant dans la chap sol idaire au tube, assure une liberté de mouvement selon l'axe longitudinale des poutres tout en garantissant leur fonction de support du tube. According to a characteristic of the invention, each beam comprises near its free end a finger which, turned on the side of the other beam, is intended to be engaged in a clevis integral with the tube, whose opening is turned on the side. from the bottom of the tube. In this way, the finger present on the beams, sliding in the chap sol idaire tube, provides freedom of movement along the longitudinal axis of the beams while ensuring their support function of the tube.
Selon un mode de réalisation du dispositif, le tube possède une section qui varie sur sa longueur, la section dans la zone de l'ouverture étant inférieure à la section dans la zone du fond du tube.  According to one embodiment of the device, the tube has a section that varies along its length, the section in the area of the opening being smaller than the section in the region of the bottom of the tube.
Cette forme offre une fonction de confinement du souffle de l'explosion offrant ainsi une poussé plus importante sur le manteau neigeux et donc un déclenchement d'avalanche optimisé.  This shape offers a function of confining the blast of the explosion thus offering a greater push on the snowpack and thus an optimized avalanche release.
La section du tube peut être circulaire ou autre, par exemple elliptique.  The section of the tube may be circular or other, for example elliptical.
L'invention sera bien comprise à l'aide de la description qui suit en référence au dessin schématique annexé, représentant à titre d'exemple non limitatif d'exécution de ce dispositif de déclenchement d'avalanches.  The invention will be better understood with the aid of the description which follows with reference to the appended schematic drawing, representing by way of non-limiting example of execution of this avalanche triggering device.
Figure 1 en est une vue schématique de coté, en situation ;  Figure 1 is a schematic side view, in situation;
Figure 2 en est une vue en perspective ;  Figure 2 is a perspective view;
Figure 3 en est une vue en perspective du support du dispositif ; Figure 3 is a perspective view of the support of the device;
Les figures 4 a et 4 b représentent, des vues de coté du montage mobile entre le tube exploseur et les poutres de maintien, respectivement au repos et au maximum de déplacement du tube. Figures 4a and 4b show side views of the movable assembly between the exploder tube and the support beams, respectively at rest and at maximum displacement of the tube.
Le dispositif illustré sur la figure 1 comporte un tube exploseur 1 à fond fermé dont l'ouverture 2 est tournée vers un manteau neigeux 3. Ce tube 1 comporte un moyen de montage 4 sur un support 5 fixé au moyen d'un bloc en béton 6 sur le flanc de la montagne 7. Le dispositif comporte en outre un moyen de remplissage du tube par un mélange gazeux explosif 8, ce mélange servant à réaliser l'explosion visant à déclencher l'avalanche. Le dispositif comporte aussi des poutres 9 reliées au support 5 et supportant le tube exploseur 1 .  The device illustrated in FIG. 1 comprises an exploder tube 1 with a closed bottom whose opening 2 is turned towards a snowpack 3. This tube 1 comprises a mounting means 4 on a support 5 fixed by means of a concrete block 6 The device further comprises a means of filling the tube with an explosive gas mixture 8, this mixture serving to carry out the explosion aimed at triggering the avalanche. The device also comprises beams 9 connected to the support 5 and supporting the exploder tube 1.
Le dispositif ainsi formé utilise le principe de fonctionnement suivant. Lors du déclenchement d'une avalanche par un opérateur, le tube exploseur 1 est rempli par un mélange gazeux explosif composé d'une combinaison bien définie de gaz comburant et carburant, ceci à partir du moyen de remplissage 8. Un moyen d'amorçage, non illustré ici, permet ensuite de déclencher l'explosion dudit mélange. Le souffle de l'explosion qui en résulte est dirigé, par l'ouverture 2 du tube 1 , vers le manteau neigeux 3 qui, en raison de son instabilité, se détache du flanc de la montagne 7 déclenchant ainsi une avalanche. Lors de cette opération le souffle de l'explosion va transmettre une force horizontale au tube 1 . Cette force engendre un déplacement du tube 1 , qui est avantageusement amorti par les poutres 9 limitant ainsi les efforts transmis sur le support 5. The device thus formed uses the following operating principle. When triggering an avalanche by an operator, the exploder tube 1 is filled with an explosive gaseous mixture composed of a well-defined combination of oxidant gas and fuel, this from the filling means 8. A means of initiation, not illustrated here, then allows to trigger the explosion of said mixture. The resulting blast of the explosion is directed, through the opening 2 of the tube 1, to the snowpack 3 which, because of its instability, is detached from the side of the mountain 7 triggering thus an avalanche. During this operation the blast of the explosion will transmit a horizontal force to the tube 1. This force causes a displacement of the tube 1, which is advantageously damped by the beams 9 thus limiting the forces transmitted on the support 5.
Une forme de réalisation de ce dispositif est illustrée sur les figures An embodiment of this device is illustrated in the figures
2 à 4. 2 to 4.
Dans cette forme de réalisation, comme illustré sur la figure 2, le dispositif comporte un tube exploseur 1 monté articulé sur un support 5 monté fixe sur un bloc en béton 6. Ce montage est réalisé au moyen de deux paliers 14 sur le support dans lesquels se glissent deux autres paliers, non illustrés ici, présents à l'arrière du tube 1 . Ces différents paliers sont associés au moyen de pivots, non représentés, selon un axe horizontal perpendiculaire à l'axe du tube 1 . Le montage ainsi réalisé permet un mouvement de rotation vers le haut du tube 1 par rapport au support 5. Deux poutres 9, en acier à haute limite d'élasticité, sont fixées au support de part et d'autre du tube 1 . La fixation de ces deux poutres est consolidée au moyen de renforts latéraux 10. Elles présentent en outre une solidarisation latérale obtenue au moyen de plaques métalliques 1 1 en forme de berceau de manière à ne pas entraver le tube. Les deux poutres 9 présentent chacune, également, à leur extrémité libre un doigt 1 2 qu i est tourné du coté de l'autre poutre. Ce doigt 12 est destiné à être engagé dans une glissière longitudinale 1 3 sol idaire du tu be 1 , orientée sensiblement parallèlement au tube. Le montage ainsi réalisé permet un déplacement libre, selon la direction horizontal, du tube 1 par rapport aux poutres 9 tout en assurant, par les poutres 9, le soutien vertical . La forme de réalisation présente en outre une cornière métallique 14 facilitant l'installation du tube 1 sur les poutres 9 en offrant un guidage des doigts 1 2 lors de leur insertion dans les pièces 13.  In this embodiment, as illustrated in FIG. 2, the device comprises an exploder tube 1 mounted articulated on a support 5 fixedly mounted on a concrete block 6. This assembly is carried out by means of two bearings 14 on the support in which two other bearings, not illustrated here, are inserted at the rear of the tube 1. These different bearings are associated by means of pivots, not shown, along a horizontal axis perpendicular to the axis of the tube 1. The assembly thus produced allows a rotational movement towards the top of the tube 1 relative to the support 5. Two beams 9, made of steel with a high yield strength, are fixed to the support on either side of the tube 1. The fixing of these two beams is consolidated by means of lateral reinforcements 10. They furthermore have lateral fastening obtained by means of metal plates 1 1 cradle-shaped so as not to impede the tube. The two beams 9 each also have at their free end a finger 1 2 which is rotated on the side of the other beam. This finger 12 is intended to be engaged in a longitudinal slide 1 3 sol idaire of you be 1, oriented substantially parallel to the tube. The assembly thus produced allows a free movement, in the horizontal direction, of the tube 1 relative to the beams 9 while ensuring, by the beams 9, the vertical support. The embodiment further has a metal angle 14 facilitating the installation of the tube 1 on the beams 9 by providing a guide fingers 1 2 during their insertion into the parts 13.
Le fonctionnement du dispositif ainsi formé est le suivant. Lors du déclenchement de l'explosion, la force engendrée par le souffle de l'explosion génère un mouvement de rotation vers le haut du tube 1 par rapport au support 5. Ce mouvement de rotation du tube 1 est limité et amorti par les poutres 9. En effet, lors de la rotation du tube 1 , la prise des doigts 12 par les pièces 13, engendre u n dépl acement vers l e h aut d es do igts 1 2. Ce déplacement emporte, par la même, l'extrémité des poutres 9 présentant les dits doigts 12. Ceci produ it une flèche des poutres 9 permise par le choix du matériau les constituant, à savoir, un acier à haute limite d'élasticité. Cette déformation des poutres 9 engendre alors des forces de rappel qui ont pour effet de dissiper une partie de l'énergie transmise au tube exploseur 1 lors de l'explosion. Cette dissipation d'énergie est rendue possible par le déplacement horizontal libre du tube 1 par rapport aux poutres 9 qui permet d'optimiser le transfert des forces de rappel dans la direction verticale et donc une réduction du mouvement du tube 1 comme l'illustre les figures 4a et 4b. Ainsi l'angle du tube 1 par rapport à l'horizontale, dans cet exemple, est limité en passant alors d'une valeur a1 au repos de 17°, à une valeur o2 de 19.5° a u m axi m u m d e rotation. Le déplacement horizontal des chapes 1 3 par rapport aux doigts 12, quant à lui, reste aussi contenu, variant alors de la valeur d1 d'environ 5 cm au repos à la valeur d2 de prés de 8 cm au maximum de déplacement. C'est ce déplacement horizontal libre du tube 1 par rapport aux poutres 9 qui permet d'optimiser le transfert des forces de rappel dans la d irection verticale et donc d'assurer l'amortissement du déplacement du tube. Cet amortissement aboutit donc à une réinitialisation rapide du dispositif qui, en reprenant sa configuration au repos, offre la possibilité de réal isation d'un second tir de déclenchement d'avalanche. The operation of the device thus formed is as follows. When triggering the explosion, the force generated by the blast of the explosion generates a rotational movement towards the top of the tube 1 relative to the support 5. This rotational movement of the tube 1 is limited and damped by the beams 9 Indeed, during the rotation of the tube 1, the gripping of the fingers 12 by the pieces 13, causes a displacement towards the other of the fingers 1 2. This displacement carries, by the same, the end of the beams 9 12. This produces an arrow of the beams 9 enabled by the choice of the material constituting them, namely, a steel with a high yield strength. This deformation of beams 9 then generates restoring forces which have the effect of dissipating part of the energy transmitted to the exploder tube 1 during the explosion. This energy dissipation is made possible by the free horizontal displacement of the tube 1 with respect to the beams 9 which makes it possible to optimize the transfer of the restoring forces in the vertical direction and therefore a reduction of the movement of the tube 1 as illustrated by FIGS. Figures 4a and 4b. Thus, the angle of the tube 1 with respect to the horizontal, in this example, is limited by passing then from a value a1 at rest of 17 °, to a value o2 of 19.5 ° aum axi mum of rotation. The horizontal displacement of the clevises 1 3 with respect to the fingers 12, meanwhile, also remains contained, then varying from the value d1 of about 5 cm at rest to the value d2 of nearly 8 cm maximum displacement. It is this free horizontal displacement of the tube 1 with respect to the beams 9 which makes it possible to optimize the transfer of the restoring forces in the vertical direction and thus to ensure the damping of the displacement of the tube. This damping therefore results in a rapid reset of the device which, by resuming its configuration at rest, offers the possibility of realisation of a second avalanche triggering firing.
Comme il va de soi, l'invention ne se limite pas aux formes de réalisations décrites ci-dessus. Elle pourra notamment mettre en œuvre une plural ité de poutres pour assurer une optim isation de l'amortissement des déplacements du tube exploseur ou encore utiliser des poutres en matériau composite tel que, par exemple, de la fibre de carbone. En outre les moyens de liaison mobile entre l'extrémité avant du tube et les poutres pourraient être inversés, chaque poutre comportant, à proximité de son extrémité libre, une glissière longitudinale dans laquelle est engagé un doigt solidaire du tube.  It goes without saying that the invention is not limited to the embodiments described above. It may in particular implement a plurality of beams to ensure optim ization of the damping movements of the exploder tube or use beams of composite material such as, for example, carbon fiber. In addition, the mobile connection means between the front end of the tube and the beams could be inverted, each beam having, near its free end, a longitudinal slide in which is engaged a finger secured to the tube.
