Abstract

Drilling apparatus, in particular for drilling of holes preferably in soil consisting essentially of glacier deposits or comparatively soft rocks, said drilling apparatus comprising a drilling pipe with a cutter head, the drilling pipe consisting of two coaxial pipes forming an interspace, through which a drilling medium such as water or air can be introduced, and in which drilling pipe the cutter head is placed on the end, which is in front during the drilling, the cutter head comprising a number of hard metal bits and nozzles in between, through which the drilling medium can flow under pressure. To obtain an effective conveyance of the material removed during the drilling through the inner of the drilling apparatus, through which it should also be possible to introduce for instance liners, the drilling apparatus is constructed in such a way that the clear of the inner one of the coaxial pipes is unobstructed, that in addition to the nozzles in the cutter head a number of radially inwards directed nozzles is provided at a short distance from the cutter head and a number of ejector nozzles, which is directed obliquely inwards in a direction away from the cutter head.
