Abstract

En selvborende fjellbolt (10) består av en stang (13) og en forankringsinnretning (23). En første ende (11) av bolten har et boreskjær (16) for å gjennomtrenge berg, og en andre ende (12) tilpasset for forbindelse med en boreanordning for å muliggjøre rotasjon av, og press på, bolten. En sirkulasjonskanal er tilveiebrakt for å tilføre væske til boreskjæret (16), og i en utførelse er en sentral kanal tilvirket i stangen (13) for å danne en del av denne sirkulasjonskanalen. Forankringsinnretningen (23) virker ved å fastholde bolten når den er plassert i et borehull, og omfaller en kilehylse (29) med en eller flere skrånende ytre flater (29, 30) montert på, eller integrert med, stangen (13), og minst ett ekspansjonselement (24) anbrakt over kilehylsen. Ekspansjonselement(ene). (24) forskyves radielt utover ved en forhåndsbestemt relativ bevegelse mellom kilehylsen (29) og elementet (24).
