The filling equipment is connected to the drill hole (2) so that a pipe in it issues into the hole. An integral funnel-shaped body (5) tightly connects to the mouth of the drill hole. The material drilled out of the hole is mixed with water, and the thus produced slurry is fed through the pipe down into the drill hole where it precipitates at the bottom. The water which is collected in the drill hole above the sedimented material is made to circulate by being sucked upwards through a suction pipe provided with a slurry pump (6), and conducted to the funnel-shaped body (5) of the filling equipment. In the funnel-shaped body, the water is mixed with further drilling waste, and the sedimentation process is contained until the drill hole is completely filled. |
