Abstract
A resin insertion device includes a barrel, a piston within the barrel, and a triggering mechanism. The triggering mechanism includes an air outlet, an air inlet, a venturi tube and at least one trigger piston. A resin insertion device includes a barrel having a collar disposed at a first end and a piston disposed slidably within the barrel. A triggering mechanism is disposed at a second end. A first position of the trigger prevents airflow through an air inlet, a second position allows air through the inlet and an outlet, and a third position prevents airflow through the outlet. A method of inserting resin into a bore hole includes providing an insertion device including a barrel, and a triggering mechanism. The method includes depressing a trigger from a first to a second position, placing at least one resin cartridge within the barrel, and further depressing the trigger.
