Injection head for insertion of two components resin into rock mass, particularly in to subsurface mining and tunnel construction, has distributor block with connections for component lines and has connection to injection bore anchor

摘要

The injection head (1) has a distributor block (2) with connections for the component lines (4,6) and has a connection to the injection bore anchor (10). The component lines are implemented extending from the distributor block with assigned return valves (7) into the inner canal (12) of the injection drilling anchor and have pressing bushing at the end side. The pressing bushing is designed movable on the component lines and turning up on the outer thread (11) of the injection drilling anchor, where the inner channel is designed for receiving the static mixer.
