Abstract
Dispositif de perçage et son utilisation pour une cuve de stockage d’un liquide. L’invention concerne un dispositif de perçage d’une paroi comportant un manchon d’enrobage (12) cylindrique, fixé autour d’une portion longitudinale du foret (11), présentant un diamètre D ainsi qu’un canon de perçage (13) dans lequel le manchon d’enrobage (12) coulisse sur au moins une longueur L lors du perçage de la paroi (6, 8, 10a, 10b), ledit canon de perçage (13) et le manchon d’enrobage (12) sont montés en ajustement glissant H7g6 tel que défini selon la norme ISO 8015, et le canon de perçage (13) et le manchon d’enrobage (12) présentent entre eux un coefficient de frottement au plus égal à 0,2 (coefficient mesurable par une méthode standardisée selon la norme ASTM G77) tandis que la distance de guidage L du manchon d’enrobage (12) dans le canon de perçage (13) est au moins égale à deux virgule cinq fois le diamètre du manchon d’enrobage (12), soit L ≥ 2,5 D. Figure pour l’abrégé : Fig. 3Drilling device and its use for a liquid storage tank. The invention relates to a device for drilling a wall comprising a cylindrical embedding sleeve (12), fixed around a longitudinal portion of the drill bit (11), having a diameter D and a drill bush (13) wherein the coating sleeve (12) slides over at least a length L when drilling the wall (6, 8, 10a, 10b), said drill bush (13) and the coating sleeve (12) are mounted in a sliding fit H7g6 as defined according to the ISO 8015 standard, and the drill bush (13) and the coating sleeve (12) have between them a coefficient of friction at most equal to 0.2 (coefficient measurable by a standardized method according to the ASTM G77 standard) while the guide distance L of the coating sleeve (12) in the drill bush (13) is at least equal to two point five times the diameter of the coating sleeve (12) , i.e. L ≥ 2.5 D.
