SPRING WATER OBSERVATION SYSTEM AND ITS INSTALLATION METHOD, AND SPRING WATER OBSERVATION METHOD
To provide a spring water observation system and its installation method, and a spring water observation method, which, in a long-term monitoring of spring water with use of a borehole, can reduce cost required for the long-term monitoring, dissolve cost and labor for pulling out boring pipes etc., and measure the water pressure inside a packer.SOLUTION: A spring water observation system 100 comprises: a double-tubing rod 30 that includes a packer 20; a flow-path-changing unit 70 that includes a flow-path-changing adapter 40 fitted with an observation meter 48, a first check valve 50 and a water-pressure-measuring device 60; a shaft-like unit 80 consisting of the double-tubing rod 30 and the flow-path-changing unit 70; a first flow path to make water reach the packer 20; and a second flow path to make spring water reach the observation meter 48. The first check valve 50 opens the first flow path when water is conveyed to the packer 20, and closes the first flow path when the returning water returns. The double-tubing rod 30 is inserted into a prepender 15 that is fitted at a hole mouth B2 of a borehole B.SELECTED DRAWING: Figure 2
【課題】ボーリング孔を利用した湧水の長期モニタリングに際して、長期モニタリングに要する費用を低減でき、削孔管等を引き抜く際の費用と手間を解消でき、パッカー内の水圧を測定することのできる、湧水観測装置とその設置方法、及び湧水観測方法を提供する。【解決手段】湧水観測装置１００は、パッカー２０を備えている二重管ロッド３０と、観測計４８が取り付けられている流路切替えアダプタ４０、第１逆止弁５０、水圧測定装置６０を備えている流路切替えユニット７０と、二重管ロッド３０と流路切替えユニット７０からなる軸状ユニット８０と、水をパッカー２０に到達させる第１流路と、湧水を観測計４８に到達させる第２流路とを有し、第１逆止弁５０は、パッカー２０へ送水する際に第１流路を開き、戻り水が戻る際に第１流路を閉じ、二重管ロッド３０がボーリング孔Ｂの孔口Ｂ２に取り付けられるプリペンダー１５に挿通されている。【選択図】図２
