Abstract

L'invention concerne un système d'étanchéité de raccord d'entrée destiné à une citerne souterraine. Ce raccord d'entrée comprend une partie à emboîtement (56), une partie bride (54), et plusieurs goujons (46) s'étendant axialement vers l'extérieur à partir de la partie bride. Ces goujons s'étendent au travers d'orifices (58) pratiqués dans la paroi (48) de la citerne, et à travers une bague (42) de compression placée à l'intérieur de la citerne. Des écrous (44) entrent en contact avec les goujons et tirent la bride contre l'extérieur de la paroi de la citerne. L'extérieur de la bride comporte plusieurs sillons (50) constituant un contact linéaire avec l'extérieur de la paroi de la citerne, et se conformant à la surface rugueuse de celle-ci en vue de réaliser une forte étanchéité avec des forces de compression relativement faibles.
