Abstract

L'invention concerne un procédé pour excaver une caverne, une caverne réalisée par le procédé et un dispositif d'accumulation d'énergie fabriqué par le procédé. Pour excaver la caverne, un dispositif à tuyaux de rinçage, présentant un premier tuyau de rinçage et un deuxième tuyau de rinçage, est introduit à travers au moins un trou de forage dans une couche saline souterraine. Ensuite, les tuyaux de rinçage effectuent une extraction par dissolution en profondeur pour former une chambre dans la couche saline et ensuite une extraction par dissolution en largeur pour élargir la chambre. Selon l'invention, plusieurs chambres sont fabriquées de la même manière les unes à côté des autres et élargies lors de l'extraction par dissolution en largeur de manière telle qu'il se forme des percements entre les chambres adjacentes respectives. La caverne est réalisée à partir de ces chambres reliées au moyen des percements avec une longueur qui est supérieure à sa profondeur.
