WATER SAMPLER, WATER SAMPLING METHOD, AND INTERSTITIAL WATER SURVEY METHOD
PROBLEM TO BE SOLVED: To sample interstitial water so as not to be exposed to the air as much as possible.SOLUTION: A water sampler 1 includes: a syringe 20; a filter 10 connected to the syringe 20; and a plug 30 provided on a passage from the filter 10 to the syringe 20, capable of opening/closing the passage. When using the water sampler 1, first of all, the filter 10 is buried in the ground, and interstitial water in the ground is allowed to pass the filter and sucked into the syringe 20 in the state where the plug 30 is opened, and then the plug 30 is closed. Hereby, interstitial water can be sampled.SELECTED DRAWING: Figure 1
【課題】間隙水を可能な限り気中に暴露しないように採水する。【解決手段】採水器１は、シリンジ２０と、シリンジ２０に連結されたフィルタ１０と、フィルタ１０からシリンジ２０内までの経路に設けられ、その経路を開閉可能な栓３０と、を備える。採水器１の使用に際しては、まずフィルタ１０を地盤に埋設し、栓３０を開いた状態で地盤中の間隙水をフィルタに通過させてシリンジ２０に吸引し、その後、栓３０を閉じる。これにより間隙水を採取する。【選択図】図１
