OBSERVATION METHOD FOR GROUND WATER AND TUBE BODY FOR OBSERVATION USED THEREFOR
PROBLEM TO BE SOLVED: To provide an observation method for ground water that can evaluate permeation water etc., through a border part between a foundation pile and an impermeable layer when the foundation pile is installed in a waste final disposal place site, and a tube body for observation used therefor.SOLUTION: While sediment in a tube body 12 for observation is excavated using the tube body 12 for observation which comprises a holed part 11, having intake holes 10, 10, ... formed to be linked inside and outside a pipe at a desired position in a tube axis direction, the tube body 12 for observation is made to further penetrate the foundation until the holed part 11 is located at an impermeable layer part 2c after being made to penetrate the foundation 2 until its lower end reaches the impermeable layer part 2b, and then the part below the holed part 11 of the tube body 12 for observation is closed with a shield body 14 to use the inside of the tube body 12 for observation as an observation well, and ground water flowing in the tube body 12 for observation through intake holes 10 is taken and analyzed to observe the ground water.SELECTED DRAWING: Figure 1
【課題】廃棄物最終処分場跡地に基礎杭を打設する場合に基礎杭と不透水層との境界部を通じた透水等を評価可能な地下水の観測方法及びそれに使用する観測用管体の提供。【解決手段】管内外で連通した取水孔１０，１０...が形成されている有孔部１１を管軸方向の所望位置に備えている観測用管体１２を使用し、観測用管体１２内の土砂を掘削しつつ、下端が不透水層部２ｂに至るまで観測用管体１２を地盤２に貫入させた後、観測用管体１２を有孔部１１が不透水層部２ｃに位置するまでさらに地盤に貫入させ、然る後、観測用管体１２の有孔部１１より下方を遮蔽体１４で閉鎖して観測用管体１２内を観測井とし、取水孔１０を通して観測用管体１２内に流入した地下水を取水して分析することにより地下水を観測する。【選択図】図１
