Abstract
PURPOSE:To make thin the sedimentation layer disabling sand lifting by a jet pump by providing a receiving pipe slantly downward and providing a jet nozzle slantly upward. CONSTITUTION:A receiving pipe 9 connected to the lower end of the sand lifting pipe 37 of a jet pump 7 is formed with a straight pipe and arranged slantly with one end opening faced backward and slantly downward. A jet nozzle 8 spraying the driving water 48 to the opening of the receiving pipe 9 is inclined slantly upward. The distance in the vertical direction from the lower end of the jet nozzle 8 to the injection port is made small, and the opening of the receiving pipe 9 can be located near the bottom of a sedimentation pit 6. The layer of sedimentation 10 disabling the sand lifting by the jet pump 7 can thereby be made thin.
