Abstract

La paroi extérieure d'un élément 1 de thermoforage est cylindrique 2. L'arête inférieure 3 est arrondie pour se raccorder à une surface tronconique bombée 4 de même axe que la paroi extérieure cylindrique 2. A l'extrémité supérieure de la surface tronconique rentrante 4 est disposée une pompe 5 qui évacue l'eau de fusion correspondant au volume du trou de forage dans la glace 8 dont la paroi possède sensiblement le même diamètre que l'équipement de thermoforage 1.
