Abstract

Ancrage d'un tirant sur une longueur limitée au fond d'un forage. Le tirant 8 est entouré d'un tube 2 pourvu d'une manchette gonflable et comportant, au-delà, une obturation provisoire annihilable; dans ce cas, un tube annelé 3 fermé au fond peut être ouvert longitudinalement par les couteaux rétractables 9 portés à l'extrémité du tirant. Ancrage de tous tirants dans tous sols, notamment pour des fins de stabilisation d'ouvrages ou de précontrainte.
