STEEL IMPERMEABLE WALL AND IMPERMEABLE METHOD OF STEEL IMPERMEABLE WALL
To provide: a steel impermeable wall having highly reliable water impermeability even when installed in a ground having an aerial part or a ground in which the aerial part sinks below the water surface; and an impermeable method of steel impermeable wall.SOLUTION: A steel impermeable wall 1 according to the present invention comprises a steel wall 11 which is installed in a ground 3 where a lower ground 3a is at or below the water surface and an upper ground 3b is above the water surface, and which steel wall comprises multiple joint-attached steel members 9 each constructed with a swellable water-impervious material 7 applied to a joint fitting portion 5, are jointly fitted to each other. The impermeable wall further comprises one or more water-impervious material filling portions 13 provided so as to be in contact with one side surface or both side surfaces of the steel wall 11 in the vicinity of at least the joint fitting portions 5 in the upper ground 3b.SELECTED DRAWING: Figure 1
【課題】気中部を有する地盤や気中部が水面下に沈下する地盤に設置された場合でも、信頼性の高い遮水性を有する鋼製遮水壁および鋼製遮水壁の遮水方法を提供する。【解決手段】本発明に係る鋼製遮水壁１は、下部地盤３ａが水面以下で上部地盤３ｂが水面より上方にある地盤３に対して、継手嵌合部５に膨潤性遮水材７が施工された複数の継手付き鋼製部材９が継手嵌合されて打設された鋼製壁１１を備えたものであって、前記上部地盤３ｂにおける少なくとも継手嵌合部５近傍の鋼製壁１１の片側面または両側面に接するように設けられた不透水性材料充填部１３を備えたものである。【選択図】 図１
