Abstract

Le dispositif (10) de déclenchement d'une avalanche comporte un canon à gaz (12) dont l'extrémité amont est fixée à une embase (13) solidement ancrée à la montagne et dont l'extrémité aval est portée par au moins un pied (14) de manière telle que l'embouchure du canon soit disposée au-dessus du manteau neigeux. L'extrémité amont du canon (12) est fixée à l'embase (13) par une articulation (17), et l'extrémité aval est lestée, le pied (14) étant posé librement sur un socle (15) rendu solidaire du terrain. Ledit pied (14) est creux et contient un lest constitué de grenaille ou de béton. Ledit canon (12) est en outre pourvu de moyens d'allumage (54) disposés au voisinage de son extrémité amont et assurant l'allumage d'un mélange gazeux détonant.
