WELL STRUCTURE, GROUNDWATER PURIFICATION SYSTEM AND GROUNDWATER PURIFICATION METHOD
To provide a well structure capable of preventing rise of water pressure in a well and safely and quickly purifying groundwater, a groundwater purification system, and a groundwater purification method.SOLUTION: A groundwater purification system 41 is formed by installing multiple well structures 2 in a ground 1, and an agent injection pump 37 on the ground injecting the agent into double pipes 5 of the well structure 2. A well 3 of the well structure 2 is separated into two sections in the depth direction by water shielding materials 23, and pumps 31-1, 31-2 are installed for moving water between the two sections. The double pipe 5 has an outer pipe 7 closed with the water shielding material 23 at a lower end and having a strainer pipe 13 above the water shielding material 23, and an inner pipe 15 penetrating through the water shielding material 23 and having a strainer pipe 21 under the water shielding material 23. The outer pipe 7 and the inner pipe 15 are opened at top ends. In another well structure 2-2 adjacent to one well structure 2-1, operation of the pumps 31-1, 31-2 are controlled to move water in the reverse direction in the upper part and the lower part.SELECTED DRAWING: Figure 3
【課題】井戸内での水圧の上昇を防ぎ、地下水を安全かつ迅速に浄化できる井戸構造、地下水浄化システムおよび地下水浄化方法を提供すること。【解決手段】複数の井戸構造２を地盤１内に、井戸構造２の二重管５内に薬剤を注入する薬剤注入ポンプ３７を地上に設置し、地下水浄化システム４１とする。井戸構造２の井戸３は、遮水材２３で深度方向に２つの区間に分けられ、２つの区間の間で水を移動させるポンプ３１−１、３１−２が設置される。二重管５は、下端が遮水材２３で塞がれ遮水材２３より上方にストレーナ管１３が設けられた外管７、遮水材２３を貫通し遮水材２３より下方にストレーナ管２１が設けられた内管１５を有し、外管７および内管２５の天端が開放される。一の井戸構造２−１と隣接する他の井戸構造２−２では、水の移動方向が互いに上下逆方向となるようにポンプ３１−１、３１−２の運転が制御される。【選択図】図３
