Method of inserting rock bolts and device for carrying out the method

摘要

The rock bolts inserted into drill holes are normally bonded in place with an adhesive agent, for example a two-component synthetic resin in the form of cartridges. First of all the cartridges are put into the drill hole and then the bolt stem is pushed into the drill hole in a rotary manner by means of a drilling device. To improve the insertion action with regard to the amount of time required and to improve the safety for the workers, a sheath (5) accommodating the cartridges (11) is slipped onto the bolt stem (3) and is pushed together with the bolt stem (3) into the drill hole (1). <IMAGE>
