Device and process of snow removal

A snow volume-reducing and fluidisation device comprising:

• a first fixed reservoir equipped with a fluidizer configured to fluidise and reduce the volume of snow;
• at least one second reservoir forming a storage basin of larger volume than the first reservoir, the volume of said storage basin being at least 20 times the volume of the first reservoir, and said storage basin being at least partly filled with water, said water being at ambient temperature;
• at least one first fluid transfer conduit between an evacuation orifice at the lower end of said first reservoir and said storage basin, said evacuation orifice enabling evacuation of a fluidised snow mixture in a lower part of the first reservoir;
• and
• at least one second transfer conduit between said storage basin and said first reservoir;
• said fluidizer comprising:
• a snow compactor comprising a mobile dynamic compactor;
• and
• a mechanical snow breaker comprising a chopper and/or a mixer arranged below said snow compactor, said mechanical snow breaker being configured to force the snow to move downwards;
• and
• at least one water injector inside and/or above the first reservoir and supplied with water from the storage basin via said second transfer conduit, said water injector being positioned at least above said chopper and/or mixer;
• and
• an ultrasound generator comprising ultrasound emitters supported by a rigid structure inside the first reservoir, arranged below said chopper and/or mixer and below said water injector.
