Definitions

  • the present invention relates to the field of preventive triggering of avalanches and more particularly relates to an avalanche triggering system as for example described in the document FR2771168 A .
  • the preventive triggering of avalanches mainly aims to secure ski areas, traffic networks, or even homes.
  • the snow cover that forms on the slope of a wall includes a set of layers of snow deposited on top of each other as precipitation occurs. These different layers are often made up of different types of snow, hence a certain heterogeneity of the snow cover, often the cause of the avalanche.
  • the preventive triggering of avalanches consists of causing a shock wave on a higher zone of the surface of the snow cover in such a way as to cause a disruption of the balance of the snow cover in this zone, and this before the accumulation of snow can cause a destructive natural avalanche.
  • a first known technique consists of having an operator place explosive charges at the precise location where the avalanche is to be triggered. This placement can be done either from a helicopter by throwing, or from the ground, the explosive charge can then be deposited, slid or launched at the appropriate location. The igniting of the charge, in both cases, is generally obtained by slow wick or electrically. The risks inherent in this technique are significant. In addition to the risks directly linked to the handling of explosives, the operator must, to place explosive charges directly on the ground, go to often steep areas with unstable snow cover.
  • Remote triggering techniques have been put in place.
  • Remote initiation techniques use military weapons such as rocket launchers or shell launchers to cause the explosion on site.
  • This type of device is not suitable for certain legislation, such as French legislation, which prohibits the storage of primed charges.
  • One way to reduce the risks associated with handling explosives is to use explosive gases to generate a shock wave used to trigger the avalanche.
  • the document FR2636729 describes a remote avalanche triggering system which operates without explosive materials and which is known under the trade mark Gazex ® .
  • Such a system comprises a barrel mounted on a concrete support and comprising an opening oriented towards the surface of the snowpack, a filling circuit configured to fill the barrel with an explosive gas mixture, and a firing device which is configured to trigger the explosion of the explosive gas mixture.
  • This type of avalanche triggering system includes a gas reserve sufficient for one season which is installed in an adjacent technical room, and a firing device which is controlled remotely.
  • this type of avalanche triggering system has complete autonomy and offers perfect safety for the operator.
  • the fixed installation of this system also makes it possible to guarantee sufficient, reproducible and long-lasting power for the protection of large avalanche paths.
  • the main disadvantages linked to this type of system are the need to carry out a heavy installation requiring a significant civil engineering operation for the system itself, the adjacent technical room and the connecting pipes connecting them and the need to carry out its maintenance on the installation site which is, by definition, difficult to access.
  • the present invention aims to remedy these drawbacks.
  • the present invention aims to remedy all or part of these drawbacks.
  • the technical problem underlying the invention therefore consists of providing an avalanche triggering system which is simple and economical in structure, while limiting the risk of injury to an operator.
  • Such a configuration of the avalanche triggering system allows the transport of the latter by an operator and therefore does not require the carrying out of civil engineering operations for the installation on site of the avalanche triggering system, which significantly reduces the costs of using the avalanche triggering system, as well as visual nuisance on the operating site.
  • the avalanche triggering system according to the present invention has a simple and economical structure, while considerably limiting the risk of injury to an operator.
  • the avalanche triggering system may also have one or more of the following characteristics, taken alone or in combination.
