<p>PROBLEM TO BE SOLVED: To provide a method and a device for observing groundwater, by which the measurement of ground water in an underground section, observation performance and reliability are improved by forming the water columns of groundwater at every aquifer to a pipe for measurement connected to the groundwater intake section of internal external double pipes, annexing a water pressure sensor to the groundwater intake section and measuring and observing a water level and water pressure. SOLUTION: Groundwater intake sections 4a-4c partitioned by internal external partitioning means 11, 12 on the upper and lower sides in response to aquifers a1-a3 based on boring detection are formed between the outer pipe 2 and inner pipe 3 of strainer double pipes, the communicated pipes 5a-5c for measurement are communicated in the strainer double pipes, the strainer double pipes are set into a boring pit, groundwater in the aquifers is taken into the groundwater intake section, groundwater is introduced into the communicated pipes for measurement, and the water levels of groundwater in the aquifers introduced into the pipes for measurement are measured by water level sensors 21a. The water levels are measured for a prolonged term as required, and water pressure is measured by a water pressure sensor 22a.</p> |
