Abstract

Fremgangsmåte og apparat for fjellbolting, hvor en rørformet fjellbolt (2) med lukket tverrsnitt blir ført inn og ekspandert for forankring inne i et borehull (12). Den får da kontakt med borehullets vegg. Et strekkelement (3, 7, 8, 9) er anordnet i et ytre parti. (14) av borehullet (12) og har en indre del (7) festet til bolten under forspenning. Et herdbart medium injiseres i borehullets ytre parti (14) mellom strekkelementet (3) og borehullets vegg, nemlig i et hulrom (27) som her dannes, hvoretter mediet tillates herding.
