Groundwater sampling device and groundwater sampling method

摘要

PROBLEM TO BE SOLVED: To provide a groundwater collecting device capable of collecting groundwater with a simple configuration.;SOLUTION: A groundwater collecting device comprises: a water collecting pipe having one open end, the open end closed by a plug and the inside being at a pressure lower than atmospheric pressure; a water collecting pipe holding portion for holding at least a part, except the open end, of the water collecting pipe; driving means for driving the water collecting pipe holding portion in the vertical direction; a water catchment portion having a syringe needle and a water catchment body connected to the syringe needle; and a housing for internally accommodating the water collecting pipe holding portion holding the water collecting pipe, the drive means, and the water catchment portion excluding the water catchment body. The syringe needle is made to penetrate the plug by lowering the water collecting pipe holding portion holding the water collecting pipe by the driving means, so that a groundwater flowing from the water catchment body is collected in the water collecting pipe.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
