WATER SAMPLING PORT UNIT USED FOR GROUNDWATER OBSERVATION WELL AND GROUNDWATER OBSERVATION WELL
To suppress a disturbance of surrounding groundwater regions, to ensure stable water sampling, and to reduce the labor and cost of work with a simple structure by adjusting the amount of water sampling.SOLUTION: A water sampling port unit used for a groundwater observation well comprises a water sampling casing 12 inserted into a water sampling observation hole, a screen provided at a lower end 12a of the water sampling casing 12, a water sampling port 2 that is detachably provided at an upper part of the screen with respect to the water sampling casing 12 and communicates with the inside of the water sampling casing 12 so as to be openable and closable, and a channel opening/closing part 3 that closes the water sampling port 2 during normal operation and opens the water sampling port 2 during water sampling.SELECTED DRAWING: Figure 2
【課題】採水量の調整を可能とすることで、周辺の地下水場の乱れを抑制することができ、安定した採水を行うことができ、さらに簡単な構造で作業の手間やコストの低減を図ることができる。【解決手段】採水用の観測孔内に挿入された採水用ケーシング１２と、採水用ケーシング１２の下端部１２ａに設けられたスクリーンと、を備え、スクリーンの上部で採水用ケーシング１２に対して着脱可能に設けられ、採水用ケーシング１２の内部に連通し、開閉可能に設けられた採水口２と、通常時は採水口２を閉じ、採水時には採水口２を開く流路開閉部３と、を備えた構成の地下水観測井に用いる採水口ユニットを提供する。【選択図】図２
