confined aquiferとは 意味・読み方・使い方

To provide a method for excavating the ground, by which the cohesive soil ground having a high underwater level at an extremely deep point and the ground having a water impermeable layer, such as fine sand layer containing a number of fine grains, with a confined aquifer underheath can be safely excavated while preventing board swelling at an excavation bottom face and boiling.例文帳に追加

大深度で地下水位の高い粘性土地盤や細粒分の多い細砂層のような難透水層とその下に被圧帯水層が存在する地盤における地盤の掘削を、掘削底面の盤ぶくれやボイリングを阻止しながら安全に行うことの可能な地盤の掘削方法を提供する。 - 特許庁

The underground heat exchange system includes: the underground continuous wall 11 reaching an impermeable layer 7; the heat exchange pipe 20 laid on the excavation bottom 13 in the excavation space formed by excavating the region surrounded by the underground continuous wall 11; and a supply pipe 18 supplying the underground water of a confined aquifer 8 deeper than the impermeable layer 7 to the portion where the heat exchange pipe 20 is laid.例文帳に追加

不透水層７に達する地中連続壁１１と、前記地中連続壁１１に囲まれた領域が掘削されて形成された掘削空間の掘削底１３に敷設された熱交換パイプ２０と、前記熱交換パイプ２０が敷設された部位に前記不透水層７より深い被圧帯水層８の地下水を供給する供給管１８と、を有する。 - 特許庁
