PROBLEM TO BE SOLVED: To prevent and maintain the soil particle inflow in pumping with a simple structure.SOLUTION: A pumping well structure 1 on the present invention is constituted by building up a non-hole pipe 4 in a drilling hole 5 formed in the ground 2, and can pump up this by making underground water of a water bearing layer 3 expanding in the ground 2 flow in an inside space of the non-hole pipe 4. The non-hole pipe 4 is built up in the drilling hole 5 in a substantially vertical attitude so that its opening end 8 becomes the downward direction, and the drilling hole 5 is formed so that the depth of its bottom part 9 becomes the under surface boundary vicinity of the water bearing layer 3, and the non-hole pipe 4 is positioned so that the depth of its opening end 8 becomes the upper surface boundary vicinity of the water bearing layer 3. Here, in a space expended to the lower end vicinity of the drilling hole 5, that is, a columnar space 10 enclosed by a hole wall formed in the water bearing layer 3 and the inside space 11 in the opening end 8-vicinity of the non-hole pipe 4 extending to its upper part, gravel 7 as a first water permeable material is filled in a shape of stacking on a bottom part 9 of the drilling hole 5.
【課題】 揚水時の土粒子流入を簡易な構造で防止しかつ保守する。【解決手段】 本発明に係る揚水井戸構造1は、地盤2に形成された掘削孔5に無孔管4を立て込んで構成してあり、地盤2内に拡がる帯水層3の地下水を無孔管4の内部空間に流入させてこれを揚水できるようになっている。無孔管4は、その開放端8が下向きとなるようにほぼ鉛直姿勢で掘削孔5に立て込んであり、掘削孔5は、その底部9の深さが帯水層3の下面境界近傍となるように形成してあるとともに、無孔管4は、その開放端8の深さが帯水層3の上面境界近傍となるように位置決めしてある。ここで、掘削孔5の下端近傍に拡がる空間、すなわち帯水層3に形成された孔壁に囲まれた円柱状空間10とその上方に延びる無孔管4の開放端8近傍における内部空間11には、掘削孔5の底部9に積み上げる形で第1の透水性材料としての砂利7を充填してある。【選択図】 図1
