DISPOSITIF WT PROCZDE PIRMITTUT DZ PROVOQUER DES
CHUTES DE NEIGE
L'invention concerne un dispositif et un procédé permettant de provoquer des glissements et des chutes de neige a un moment et dans des zones déterminés.WT PROCZDE PIRMITTUT DZ DEVICE TO CAUSE
SNOWFALL
The invention relates to a device and a method for causing slipping and snowfall at a given time and in specific areas.
L'accumulation de neige, lors d'hivers particulièrement enneigés et à des endroits où les précipitations sont de façon inattendues abondantes peut être la source d'accidents et/ou de dommages sur essentiellement deux sites à risques
le premier concerne les sites montagneux avalancheux dans lesquels à tout moment des personnes peuvent se retrouver ensevelies sous la neige.Accumulation of snow, during particularly snowy winters and in places where the precipitation is unexpectedly abundant can be the source of accidents and / or damage on essentially two risk sites
the first concerns the avalanche mountainous sites in which people can find themselves buried under the snow at any time.
le second concerne le toit des batiients, des maisons ou chalets en toutes zones montagneuses pour lequel l'accumulation de neige peut conduire a l'effondrement des toits ou à des accidents dues au glissement de la masse neigeuse au moment du redoux. the second concerns the roof of buildings, houses or chalets in all mountainous areas for which the accumulation of snow can lead to the collapse of roofs or to accidents due to the sliding of the snow mass during the downpour.
Pour la première catégorie de risque, on connais déjà des dispositifs permettant, soit d'éviter l'accumulation de neige lors de précipitations abondantes, soit de provoquer les avalanches au moment voulu. For the first risk category, devices are already known which make it possible either to avoid the accumulation of snow during heavy precipitation, or to trigger avalanches at the desired time.
Pour les seconds sites à risque, on connais également déjà des dispositifs de protection pare-neige mais qui ont un résultat mitigé lors de fortes chutes de neige;
Un objet de la présente invention est donc de proposer un dispositif permettant de provoquer des chutes de neige à un moment et dans des zones déterminés qui pallient les inconvénients ou limites de ceux connus de l'état de la technique.For the second sites at risk, we also already know snow protection devices but which have a mixed result during heavy snowfall;
An object of the present invention is therefore to propose a device making it possible to cause snowfall at a time and in specific areas which overcome the drawbacks or limits of those known from the prior art.
Un autre objet de la présente invention est de proposer un tel dispositif permettant d'éviter de façon réelle les amoncellements de neige sur des sites à risques. Another object of the present invention is to provide such a device making it possible to effectively avoid the accumulation of snow on risky sites.
Un autre objet de la présente invention est de proposer un tel dispositif permettant d'être mis en place sur les sites à risques quelque soit leur configuration ou leur topographie. Another object of the present invention is to provide such a device making it possible to be installed on risk sites whatever their configuration or their topography.
Enfin, un autre objet de la présente invention est de proposer un procédé permettant de provoquer des chutes de neige à un moment et dans des zones déterminés dont la mise en oeuvre est simple, fiable et répétitive. Finally, another object of the present invention is to propose a method making it possible to cause snowfall at a time and in specific areas the implementation of which is simple, reliable and repetitive.
A cet effet, l'invention concerne un dispositif permettant de provoquer des glissements et des chutes de neige à un moment et dans des zones déterminés caractérisé en ce qu'il comprend au moins une chambre étanche en matière souple susceptible de prendre une forme opérationnelle par la mise en oeuvre d'un moyen de gonflage. To this end, the invention relates to a device making it possible to cause slippage and snowfall at a time and in determined zones, characterized in that it comprises at least one sealed chamber made of flexible material capable of taking an operational form by the implementation of an inflation means.
La chambre a une forme et un volume déterminés en fonction de la zone dans laquelle on désire provoquer la chute de neige. The chamber has a shape and a volume determined according to the area in which it is desired to cause snowfall.
L'invention concerne également un procédé permettant de provoquer des glissements et des chutes de neige à un moment et dans des zones déterminées, caractérisé en ce qu'il comprend les étapes consistant successivement à
Mettre en place en automne ou avant les chutes de neige au moins un dispositif sur un site à risque ;
Gonfler la chambre du dispositif après une chute de neige
Dégonfler ensuite ladite chambre jusqu'à la prochaine chute de neige.The invention also relates to a method making it possible to cause slippage and snowfall at a time and in determined zones, characterized in that it comprises the steps consisting successively of
Set up at least one device in fall or before snowfall on a risk site;
Inflate the device chamber after a snowfall
Deflate the said chamber until the next snowfall.
Le dispositif selon l'invention peut donc être mis en place sur tout site à risque, avalancheux ou non, en fonction de leurs configuration et topographie. The device according to the invention can therefore be set up on any risk site, avalanche or not, depending on their configuration and topography.
Les autres caractéristiques et avantages de la présente invention seront bien compris à la lecture de la description qui suit en référence aux dessins annexés dans lesquels
Les figures 1A et 1B représentent une vue schématique, en coupe, d'un dispositif selon l'invention, respectivement en position de repos et en position opérationnelle, le dispositif étant installé sur le toit d'une maison ou d'un bâtiment ;
La figure 2A est une vue schématique, en coupe, d'une chambre d'un dispositif selon l'invention ;
La figure 2B est une vue schématique, de profil, d'une chambre d'un dispositif selon l'invention.The other characteristics and advantages of the present invention will be clearly understood on reading the description which follows with reference to the appended drawings in which
FIGS. 1A and 1B show a schematic view, in section, of a device according to the invention, respectively in the rest position and in the operational position, the device being installed on the roof of a house or of a building;
FIG. 2A is a schematic view, in section, of a chamber of a device according to the invention;
FIG. 2B is a schematic view, in profile, of a chamber of a device according to the invention.
L'invention concerne donc un dispositif permettant de provoquer des glissements et des chutes de neige & un moment et dans des zones déterminées. Un tel dispositif trouve notamment une application pour les sites montagneux avalancheux ou pour le toit des maisons, bâtiments ou chalets. The invention therefore relates to a device making it possible to cause slippage and snowfall at a time and in specific areas. Such a device finds an application in particular for mountainous avalanche sites or for the roof of houses, buildings or chalets.
Selon l'invention, le dispositif comprend au moins une chambre 1 étanche en matière souple, susceptible de prendre une forme opérationnelle par la mise en oeuvre d'un moyen de gonflage 2. According to the invention, the device comprises at least one sealed chamber 1 made of flexible material, capable of taking an operational form by the use of an inflation means 2.
La matière souple à partir de laquelle est fabriquée la chambre 1 du dispositif conforme à l'invention peut etre de façon connue du caoutchouc ou une autre matière plastique ou toilée, l'essentiel est qu'elle permette à la chambre 1 d'épouser la paroi sur laquelle elle repose et de former une pente permettant à la masse neigeuse de glisser par son propre poids. The flexible material from which is made the chamber 1 of the device according to the invention may be in a known manner of rubber or another plastic or canvas material, the main thing is that it allows the chamber 1 to marry the wall on which it rests and form a slope allowing the snow mass to slide by its own weight.
La forme et le volume de la chambre 1 du dispositif selon l'invention sont déterminés en fonction de la zone dans laquelle on désire provoquer la chute de neige. The shape and the volume of the chamber 1 of the device according to the invention are determined as a function of the zone in which it is desired to cause the snowfall.
Selon une caractéristique importante de la présente invention, en position opérationnelle la chambre 1 présente, en coupe longitudinale, une cote amont a supérieure à la cote aval b. Dans la présente invention, on entend par "amont" le côté de la chambre 1 situé vers le sommet de la montagne ou du toit de la maison, et par "aval" le côté de la chambre 1 opposé au côté amont. According to an important characteristic of the present invention, in the operational position the chamber 1 has, in longitudinal section, an upstream dimension a greater than the downstream dimension b. In the present invention, the term "upstream" means the side of the chamber 1 located towards the top of the mountain or the roof of the house, and the term "downstream" the side of the chamber 1 opposite the upstream side.
En position opérationnelle, la chambre 1 présente en outre, en coupe longitudinale au moins une inclinaison 3 sur au moins toute ou partie de sa longueur. In the operational position, the chamber 1 also has, in longitudinal section, at least one inclination 3 over at least all or part of its length.
Comme mentionné ci-dessus, la chambre 1 du dispositif conforme à la présente invention a une forme qui est déterminée en fonction de la zone dans laquelle on désire provoquer la chute de neige. As mentioned above, the chamber 1 of the device according to the present invention has a shape which is determined according to the area in which it is desired to cause snowfall.
C'est ainsi, qu'en position opérationnelle, la chambre 1 peut présenter en coupe longitudinale sensiblement la forme d'un triangle rectangle (figures 1B, 2A). Mais la chambre 1 peut également présenter, en position opérationnelle, une forme de boudin (figure 2B) ou meme la forme d'une grille de boudin. Thus, in the operational position, the chamber 1 can have in longitudinal section substantially the shape of a right triangle (Figures 1B, 2A). However, the chamber 1 can also have, in the operational position, a shape of a sausage (FIG. 2B) or even the shape of a sausage grid.
Le moyen de gonflage 2 permettant de gonfler la chambre 1 du dispositif conforme à la présente invention est choisi dans le groupe comprenant des moyens de gonflage par gaz comprimé, et ce peut être alors des compresseurs et/ou des bouteilles de gaz comprimé ou équivalents. Le moyen de gonflage 2 peut être également choisi parmi ceux obtenus par réaction explosive entre des produits chimiques par analogie au système des poches anti-chocs de véhicules automobiles. The inflation means 2 making it possible to inflate the chamber 1 of the device according to the present invention is chosen from the group comprising inflation means using compressed gas, and this can then be compressors and / or bottles of compressed gas or the like. The inflation means 2 can also be chosen from those obtained by explosive reaction between chemicals by analogy to the system of shock-absorbing pockets of motor vehicles.
Pour faciiter les chutes de neige, le dispositif conforme à la présente invention peut comprendre un moyen de chauffage des moyens 2 de gonflage. To facilitate snowfall, the device according to the present invention may include a means for heating the inflation means 2.
L'invention concerne également un procédé permettant de provoquer des glissements et des chutes de neige à un moment et dans des zones déterminés, caractérisé en ce qu'il comprend les étapes consistant successivement à
mettre en place en automne ou avant les chutes de neige au moins un dispositif selon l'invention sur un site à risque. Une telle installation est tres facile à réaliser puisqu'il suffit de solidariser l'extrémité amont de la chambre 1 du dispositif à la paroi que l'on voudra déneiger, et à laisser dérouler la chambre 1 le long de la pente de la zone à déterminer ;
gonfler la chambre 1 du dispositif apres une chute de neige par le moyen de gonflage 2 raccordé à la chambre 1 ;
dégonfler ensuite ladite chambre 1 jusqu'à la prochaine chute de neige. The invention also relates to a method making it possible to cause slippage and snowfall at a given time and in determined zones, characterized in that it comprises the steps consisting successively of
set up in autumn or before snowfall at least one device according to the invention on a risk site. Such an installation is very easy to carry out since it suffices to secure the upstream end of the chamber 1 of the device to the wall that is to be plowed, and to allow the chamber 1 to run along the slope of the zone to determine;
inflate the chamber 1 of the device after a snowfall by the inflation means 2 connected to the chamber 1;
then deflate said chamber 1 until the next snowfall.
