Abstract

Porasovitelma, reiän tekemiseksi maaperäin tai kallioon, joka sovitelma käsittää reiän keskiosaa poraavan pilottiterän (10) ja reiän ulkokehää poraavan rengasterän (1), jolloin poraustilanteessa rengasterä (1) on sovitettu pilottiterän (10) ympärille ja pilottiterältä (10) on johdettu pyörimisliike sekä porausiskut rengasterälle (1) mainittujen terien välille sovitettujen voimaa välittävien pintojen (4-6); (7-9); (15, 16) avulla ja että rengasterä (1) on poistettavissa pilottiterän (10) ympäriltä ja siihen asennettavissa ja että edelleen rengasterän (1) ympärille kuuluu liitäntärengas (2) porattuun reikään vedettävän suojaputken liittämiseksi rengasterään (1) mainitun liitäntärenkaan välityksellä. Liitäntärengas (2) on sovitettu rengasterän (1) helman ympärille siten, että liitäntärenkaan (2) lukitukseen osallistuvista osista (13) ainakin kaksi sijaitsee sovitelman ollessa kokoonpantuna eri puolilla linjaa (L), joka kulkee rengasterän (1) pyörimistä välittävän pinnan (5) olennaisesti keskikohdan kautta.
