(57) The invention relates to a drill hole filling method whose first stage involves the drilling of a hole (PR) by using a tubular drill rod (8) through which, in the course of drilling the hole, is supplied a flushing medium via at least one opening (11) in a crushing tool into an annular space defined by hole (PR) and the outer surface of drill rod (8) for removing crushed matter from the hole. Tubular drill rod (8) is used for delivering a filler into a hole and/or into ground or bedrock surrounding a hole, said delivery being effected after an actual drilling operation. The invention relates also to an apparatus used in the filling of a drill hole and/or in the filling of ground or bedrock surrounding a hole. The apparatus includes a drilling machine (1) provided with a passaged (4) neck member (3) for fastening a tubular (9) drill rod (8) thereto. Aligned with neck member (3) is a supply housing (2) which includes at least one chamber (I) adapted to communicate along at least one connecting duct (5) included in neck member (3) with a passage (4) in the neck member. Supply housing (2) is provided with a valve (7). On the one hand, it is adapted to carry into chamber (I) a medium required both in actual drilling and in filling a drill hole. Fig. 1 |
