RECHARGE METHOD AND RECHARGE WELL SYSTEM
To provide a recharge method and a recharge well system realizing cleaning effect to prevent decrease of water injection performance.SOLUTION: A recharge well system 20 is provided with a drainage pump 25 pumping water from a recharge well pipe 21 and an atmospheric air communication valve 31 arranged on an atmospheric air communication pipe 30 installed in a ceiling plate 22 to seal an upper surface of the recharge well pipe 21, controlling air communication with an inner space of an upper part of the recharge well pipe 21. A control section 50 of the recharge well system 20 supplies water through a water injection pipe 18 by closing the atmospheric air communication valve 31, increasing pressure to inject the water in the ground. The control section 50, further, closes the atmospheric air communication valve 31 to decrease pressure in the upper space of the recharge well pipe 21, and drives the drainage pump 25 to pump the water from the recharge well pipe 21 for cleaning.SELECTED DRAWING: Figure 1
【課題】注水能力の低下を抑制できる洗浄効果を得ることができる復水工法及び復水井戸システムを提供する。【解決手段】復水井戸システム２０は、復水井戸管２１から水を汲み上げる排水ポンプ２５と、復水井戸管２１の上面を封止する天井板２２に設けた大気連通管３０に設けられ、復水井戸管２１の上部の内部空間と大気との連通を制御する大気連通弁３１とを備える。復水井戸システム２０の制御部５０は、大気連通弁３１を閉じて、注水管１８を介して水を供給し、加圧して地盤に注水する。更に、制御部５０は、大気連通弁３１を閉じて、復水井戸管２１の上部の空間を減圧して、排水ポンプ２５を駆動して復水井戸管２１から水を汲み上げる洗浄を行なう。【選択図】図１
