Abstract:
A method and an apparatus for rock reinforcement are described. The method comprises the steps: to inject a first component and a second component through a first channel and a second channel respectively into a rock hole, wherein the first component and the second component are adapted for rock reinforcement and to inject a blocking agent through a third channel into at least said second channel, wherein said blocking agent provides a barrier in at least said second channel.

Claim (Index 10):
Apparatus at rock reinforcement comprising:\n a first channel adapted for injection of first component into a rock hole, a second channel adapted for injection of second component into said rock hole, wherein said first component and said second component are adapted for rock reinforcement and a third channel for injection of a blocking agent into at least said second channel, wherein said third channel is directly connected to said second channel, wherein at least said second channel comprises a valve-piston arranged to be positioned in at least a first position and a second position, wherein said valve-piston, in said first position, is arranged to permit injection of said second component into said rock hole, and wherein said valve-piston, in said second position, is arranged to prevent injection of said second component into said rock hole and to permit injection of said blocking agent into at least said second channel characterized in that said valve-piston comprises a slot arranged so that, in said second position of the valve-piston, injection of said blocking agent is permitted into a third sub-channel of said second channel.
