Title (EN) REINFORCING AND CONFINING EARTH FORMATIONS
(FR) RENFORCEMENT ET DELIMITATION DE FORMATIONS DE TERRAIN
Abstract:
(EN) Reinforcing and confining of earth formations comprising a plurality of support members having a retaining portion (21) for anchoring in bore hole in the earth formation and an exposed portion having at least two free ends (22, 23) lying substantially against the earth formation at an angle of substantially against the earth formation at an angle of between 90o-180o to each other, the free ends having closed loops for direct interconnection with support members in adjacent bore holes to define a mesh-like structure over the surface of the earth formation. The earth formation may be reinforced by tensioning either the anchored portion of a support member in the bore hole and/or the free ends.
(FR) Renforcement et délimitation de formations de terrain comprenant une pluralité d"organes de support présentant une partie de retenue (21) permettant l"ancrage dans un trou de forage dans la formation de terrain et une partie exposée possédant au moins deux extrémités libres (22, 23) situées sensiblement contre la formation de terrain en formant entre elles un angle compris entre 90o et 180o, les extrémités libres possédant des boucles fermées pour l"interconnexion directe avec des organes de support dans des trous de forage adjacents pour définir une structure en treillis au-dessus de la surface de la formation de terrain. Celle-ci peut être renforcée en mettant sous tension la partie ancrée d"un organe de support dans le trou de forage et/ou les extrémités libres.
