CONTROL SYSTEM OF CIRCULATED WATER WELL AND CONTROL METHOD OF CIRCULATED WATER WELL
To make a circulated water well hardly be clogged.SOLUTION: In a control system 1 of a circulated water well 4 in which water is injected into the circulated water well 4 and is circulated to a ground 2: water is circulated to the circulated water well 4 by an injection pipe 12; an injection amount (Q2) into the circulated water well 4 by the injection pipe 12 is obtained by a flow meter 17; water in the circulated water well 4 is discharged by a water discharge pump 13; a discharge amount (Q3) of water in the circulated water well 4 by the water discharge pump 13 is obtained by a flow meter 18; and water in the circulated water well 4 is discharged by the water discharge pump 13 so that a circulation amount Qr into the ground 2 that is a value obtained by subtracting the discharge amount (Q3) by the water discharge pump 13 obtained by the flow meter 18 from the injection amount (Q2) by the injection pipe 12 obtained by the flow meter 17 becomes constant. Since the circulation amount Qr of the circulated water well 4 becomes stable, fine-grained fraction in the ground 2 around the circulated water well 4 can be suppressed. Clogging becomes hard to occur compared with a conventional control system where a switch of a pump of a circulated water well is turned ON and OFF, and water is circulated while a circulation amount and water level change.SELECTED DRAWING: Figure 1
【課題】復水井戸の目詰まりを生じ難くする。【解決手段】復水井戸４へ注水して地中２へ復水する復水井戸４の制御システム１において、注水管１２により復水井戸４への復水がされ、流量計１７により注水管１２による復水井戸４への注水量（Ｑ２）が取得され、排水ポンプ１３により復水井戸４の水が排水され、流量計１８により排水ポンプ１３による復水井戸４の水の排水量（Ｑ３）が取得され、排水ポンプ１３により、流量計１７により取得された注水管１２による注水量（Ｑ２）から流量計１８により取得された排水ポンプ１３による排水量（Ｑ３）を差し引いた値である地中２への復水量Ｑｒが一定になるように復水井戸４の水が排水され、復水井戸４の復水量Ｑｒが安定することで、復水井戸４の周囲の地中２の細粒分の移動を抑制でき、復水井戸のポンプのスイッチを入切して復水量と水位が変動しながら復水する従来の制御システムに比べて目詰まりが生じ難くなる。【選択図】図１
