Japanese Patent JP7351206

B2

To appropriately evaluate the performance of a well facility.SOLUTION: Provided is the evaluation method of a well facility that has a water collection well 12 and multiple water collection pipes 20 having a lot of water passing holes in the peripheral wall and connected to the water collection well 12. The evaluation method has the steps of: mounting, to pipelines 52 connected to openings of the water collection pipes 20 and arranged inside the water collection well 12, pressure measuring devices 53 measuring the pressure inside the pipelines 52, flow rate measuring devices 54 measuring water flow rates flowing through the pipelines 52 and flow rate control valves 55 controlling the water flow rates flowing through the pipelines 52; measuring the pressure and the flow rate simultaneously by the pressure measuring device 53 and the flow rate measuring device 54, while controlling the flow rate of the pipeline 52 by the flow rate controlling valve 55 for every water collection pipe 20; and evaluating the relation of a water level difference to the flow rate, by calculating the water level difference of an underground water level of surrounding soil and the well water level based on the measured pressure, and integrating the flow rates of the water collection pipes 20 for every water level difference.SELECTED DRAWING: Figure 2
