Abstract

Postupak dobivanja sidra u stijeni (2) za sidrenje u stijeni, gdje se sidro u stijeni (2) koje ima cjevasti dio sidra (4) zatvorenog poprečnog presjeka, umeće i ekspandira radi nosivog kontakta u bušotini (3) u strukturi stijene (1), naznačen time, da se duljina cjevastog dijela sidra (4) određuje tako, da je maksimalna sila trenja kod izvlačenja sidra unutar bušotine (3) sidra u stijeni s cjevastim dijelom sidra, ovom duljinom ispod predodređene maksimalne vrijednosti. Patent sadrži još 9 patentnih zahtjeva.A method of obtaining a rock anchor (2) for rock anchoring, wherein the rock anchor (2) having a tubular part of the anchor (4) of closed cross-section is inserted and expanded for bearing contact in the borehole (3) in the rock structure (1) , characterized in that the length of the tubular part of the anchor (4) is determined such that the maximum friction force when pulling the anchor inside the borehole (3) of the anchor in the rock with the tubular part of the anchor is below the predetermined maximum value. The patent contains 9 more patent claims.
