Abstract

Au fur et à mesure du percement d'une galerie souterraine en demi-section supérieure, on la garnit de demi-anneaux de voûte en éléments préfabriqués. Ces éléments comprennent deux éléments d'appui 28 symétriques et des voussoirs 29a, 29, 52 qui ont les mêmes dimensions parallèlement à l'axe de la galerie et des vérins 53 serrent les voussoirs en réagissant sur les éléments d'appui 28 dont la largeur est suffisante pour éviter le poinçonnement du sol. Application : percement de tunnels.
