Abstract
The ground anchorage means comprises a reinforcement combined with an adjacent injection tube furnished with sleeves acting as retention valves and a distensible sack intended to obturate the drilled hole. The fixing zone of the reinforcement is protected by an impervious envelope made of a rot-proof and anti-corrosive material in which the reinforcement is immersed in a hardenable material such as grouting cement. The free zone is immersed in an anti-corrosive product, which may be flexible in another envelope or sheath, the two envelopes being joined together by a sealing sleeve. Application, particularly for supporting walls.
