INSERTION PILE TYPE EARTH-RETAINING WALL
PROBLEM TO BE SOLVED: To provide an earth-retaining wall that can enlarge an excavation depth more than a conventional self-supporting earth-retaining wall by generating resistant moment by using sediment weight on the rear side and that has advantages such as having economic efficiency and preventing the extension of the construction period.SOLUTION: An insertion pile type earth-retaining wall comprises soldier beams 2,2 arranged at prescribed intervals in the horizontal direction and having a lower half part inserted into the foundation, horizontal sheathing 3,3 installed along the vertical direction between adjoining soldier beams, and an insertion pile 4 that is installed from the side part position of the soldier beam 2 to the foundation on the rear side in an insertion state and that has an insertion original side rigidly connected to the soldier beam 2. The insertion piles 4 are installed in multiple stages in the height direction, and between adjoining insertion piles in the vertical direction the insertion pile 4 located on the relatively lower side has a longer insertion length than the insertion pile 4 located on the relatively upper side.SELECTED DRAWING: Figure 1
【課題】背面側の土砂重量を利用して抵抗モーメントを発生させることにより、従来の自立式土留め壁よりも掘削深さの拡大を図るとともに、経済性に優れ、かつ工期の長期化を招かないなどの利点を備えた土留め壁を提供する。【解決手段】水平方向に所定間隔で配置されるとともに、下半部分が地盤中に挿入されている親杭２，２…と、隣接する親杭間に上下方向に沿って設置されている横矢板３，３…と、前記親杭２の側部位置から背面側地盤に挿入状態で設置されているとともに、挿入元側が前記親杭２に剛結されている挿入杭４とからなる。前記挿入杭４は、高さ方向に複数段で設置されるとともに、上下方向に隣接する挿入杭間で相対的に上部側に位置する挿入杭４よりも相対的に下部側に位置する挿入杭４の方が挿入長さが長く設定されている。【選択図】図１
