PROBLEM TO BE SOLVED: To provide a geothermal heat utilization mechanism-cum-ground desaturation mechanism that combines a geothermal heat utilization mechanism with an air bubble-containing water injection mechanism, for more efficient usage of geothermal heat and ground desaturation by injecting air bubble-containing water.SOLUTION: A geothermal heat utilization mechanism-cum-ground desaturation mechanism of the present invention includes a pumping well installed on a ground that holds groundwater, in a vertical direction leaving a prescribed interval for collecting groundwater in order to utilize geothermal heat, and a reduction well for returning used water to the ground, along with means for mixing air bubbles into the water returned to the ground by the reduction well.SELECTED DRAWING: Figure 1 |
