GROUNDWATER SAMPLING METHOD
To largely shorten work time by reducing work steps and work labor, and make it possible to perform a work using not a large device but a simple device as a device for a work for reducing work cost.SOLUTION: A groundwater sampling method includes: a first step of installing in a subsoil a plate-shaped groundwater sampling board 1 which comprises a plurality of long holes 10 extending in a longitudinal direction, is provided with openings 15 respectively communicating with the plurality of long holes 10 in an extending direction of the plurality of long holes 10 with an interval between each of them, and is formed of a water-impermeable material; and a second step of sampling groundwater at each predetermined depth by making groundwater flow into the long holes 10 from the openings 15 communicating with the long holes 10 of the groundwater sampling board 1 installed in a subsoil.SELECTED DRAWING: Figure 1
【課題】作業の工程を少なくして作業の手間を減らすことにより、作業時間を大幅に短縮するとともに、作業に用いる装置も大掛かりな装置になることなく、単純な装置で行えるようにし、作業のコストを抑える。【解決手段】長手方向に延在する複数の長孔１０を備え、複数の長孔１０にそれぞれ連通した開口部１５を、長孔１０の延在方向において互いに間隔を空けて設けるとともに、非通水性の材料で形成された板状の地下水採取ボード１を、地盤中に設置する第１工程と、地盤中に設置した地下水採取ボード１の長孔１０に連通した開口部１５より地下水を長孔１０内に流入させて、所定の深度毎の地下水を採取する第２工程と、を有する地下水の採水方法である。【選択図】図１
