ABSTRACT:
An auger (16) and a pump unit (18) are mounted on opposite sides of a tower (42). Each is moved up and down the tower by a separate chain and sprocket drive (134, 146, 158, and 136, 148, 160). The assembly (16, 18, 42) is laterally shiftable in position, so that the auger (16) can be used to drill a hole in an ice formation (14). Then, the auger (16) can be withdrawn from the hole (372), and the assembly (16, 18, 42) can be shifted sideways, and then the pump (18) can be lowered into the hole (372). The pump (18) is a helical screw pump (176, 184) combined with a vortex pump (338, 202). A helical screw pump element (184) lifts water up into the vortex pump housing essentially directly to the vortex pump impeller (338). Such impeller (338) discharges the water laterally outwardly through a nozzle (202).
