Abstract

Et trykkdrevet fraktureringsverktøy (12) for bruk ved splitting og frakturerIng av harde materialer, så som berg eller sten, betong og lignende, har to ekspander-bare ytre skall (16, 18) beregnet for bevegelse 1 motsatt retning av hverandre langs en valgt akse (X) på tvers av verktøyets (12) lengdeakse (Z). De ytre skall (16, 18) danner en sentral hulning (22) som strekker seg i lengderetningen over verktøyets lengde. Et elastomert rørformet element (24) er plassert i denne senetrale hulning (22), mellom to i lengderetningen fikserte endekonnektorer (40). Med utøvelse av et trykk på det rørformede element (24) vil de ytre skall (16, 18) ekspandere utover i en bestemt radiell retning for kontakt med veggen i et hulrom utboret i det harde materialet, og bevirke at dette materialet kløves eller splittes.
