Abstract

En foringsfres (82) er posisjonert under en ledekile (80) eller andre, alternative utløpsføringer i en borestrengsammenstilling som anvendes for å frese ut et parti av stålforingen under ledekilen (80), der seksjonsfresen (82) som beveger seg nedover og freser langs foringspartiet, bevirker til å senke ledekilen (80) ned ved siden av den utfreste foringen og tillater at borekronen og borestillingen kan kjøres langs ledekilens (80) overflate og inn i jordformasjonen. I en alternativ utførelse anvendes kombinasjonen av seksjonsfresen (82) og ledekilen (80) i åpen-hull operasjoner som ikke omfatter foringer.
