Abstract

PURPOSE: To survey the quality of water and the quantity of water every aquifer by dividing each aquifer in a casing pipe, and carrying out pumping operation with a pumping testing tube from each aquifer. CONSTITUTION: A division pumping device 18 is comprised of a casing pipe 19, a pumping testing tube 20, and a plug body 21. The pipe 19 is disposed with a first strainer 19A corresponding to a first aquifer, a second strainer 19B corresponding to a second aquifer, a third strainer 19C corresponding to a third aquifer, a first seat valve 19A1, a second seat valve 19B1, and third seat valve 19C1 respectively. Furthermore, the tube 20 is provided with a pumping testing tube valve 20A detachable to the seat valve 19C1 at its lower end, and a diameter of the valve 20A is made smaller than each opening diameter of the seat valves 19B1, 19A1, thus, when fitted in an upper stage valve seat, a diameter expanding member 20B or the like is mounted thereon. For example, as the strainer 19C is examined, the plug body 21 is seated on the valve seat 19C1 by the use of a plug body lift-fitting so as to be divided from a lower aquifer.
