WATER PROOF WALL, AND CONSTRUCTION METHOD OF WATER PROOF WALL
To provide a water proof wall which can be constructed with less excavation amount and which has both water proof property at a ground portion and a water proof property against a seepage flow in an underground portion.SOLUTION: A water proof wall includes a foundation portion 12 fixed to a ground and a main wall portion 20 disposed above the foundation portion 12. The foundation portion 12 comprises a steel sheet pile 14 and a rod-like steel material 16 attached to one wall face of the steel sheet pile 14 so that a longer direction becomes a vertical direction. The main wall portion 20 includes a wall portion connection steel material 22 and a precast wall body 24 in which a wall body hole 24X into which the wall portion connection steel material 22 is inserted is formed. In a state in which at least a part of the wall portion connection steel material 22 is positioned in the wall body hole 24X of the precast wall body 24, the precast wall body 24 is fixed to the wall portion connection steel material 22. An upper end portion of the rod-like steel material 16 of the foundation portion 12 and the a lower end portion of the wall portion connection steel material 22 of the main wall portion 20 are joined.SELECTED DRAWING: Figure 1
【課題】少ない掘削量で構築することができ、かつ、地上部での防水機能、および地下部での浸透流に対する防水機能を併せ持った防水壁を提供する。【解決手段】地盤に固定されている基礎部１２と、基礎部１２の上方に配置された本壁部２０と、を有する防水壁であって、基礎部１２は、鋼矢板１４と、鋼矢板１４の一方の壁面に長手方向が上下方向となるように取り付けられた棒状鋼材１６と、を備え、本壁部２０は、壁部連結鋼材２２と、壁部連結鋼材２２が挿入される壁体孔２４Ｘが形成されたプレキャスト壁体２４と、を有し、プレキャスト壁体２４の壁体孔２４Ｘ内に壁部連結鋼材２２の少なくとも一部が位置する状態で壁部連結鋼材２２にプレキャスト壁体２４が固定されたものであり、基礎部１２の棒状鋼材１６の上端部と本壁部２０の壁部連結鋼材２２の下端部とは接合されている。【選択図】図１
