ABSTRACT:
A drill hole filling method involves drilling of a hole by using a tubular drill rod through which, in the course of drilling, a flushing medium is supplied through at least one opening in a crushing tool into an annular space, defined by the hole and the outer surface of the drill rod, for removing crushed material from the hole. The tubular drill rod is used for delivering a filler into a hole and/or into the ground or bedrock surrounding a hole, at the end of the drilling operation. An apparatus for filling a drill hole includes a drilling machine provided with a passaged neck member for fastening a tubular drill rod thereto. Aligned with the neck member is a supply housing which includes at least one chamber adapted to communicate along at least one connecting duct included in the neck member with a passage in the neck member. The supply housing is provided with a valve which is adapted to carry into said chamber a medium required both in the actual drilling and in filling the drill hole.
