ABSTRACT:
The invention relates to a method and a device for guiding a concrete feeding hose in connection with the grout feedin rock bolting. The concrete feeding hose is therein passed by means of a feeder froma reel into a guide head supported on a feeding beam of a drilling equipment and further through the guide head into a hole drilled in the rock, and is passed back on to the reel in proportion as the hole is filled. In order to protect the feeder of the concrete feeding hose against dirt and mechanical damage, the concrete feeding hose is pushed into the guide head through a flexible guiding means.
