NAKAGOME HIDEKI

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

【課題】この発明は、地中熱利用機構と、気泡混入水注入機構とをドッキングさせることにより、より効率よく地中熱の利用と気泡混入水の注入による地盤の不飽和化を行えるようにした地中熱利用機構兼用地盤不飽和化機構を提供しようとするものである。【解決手段】この発明の地中熱利用機構兼用地盤不飽和化機構は、地下水を保持する地盤に所定間隔で鉛直方向に設置した、地中熱利用のために地下水を採取する揚水井と、利用後の水を地下に戻す還元井とを備え、前記還元井から地下に戻す水を気泡混入水とする手段を設けたことを特徴とする。【選択図】図１
