EARTH RETAINING WALL
To provide an earth retaining wall allowing an excavation depth to surely reach a predetermined depth as suppressing displacement at a top end part of the earth retaining wall and construction cost and construction period for constructing the retaining wall to be reduced as suppressing change of the ground of a rear surface of the retaining wall.SOLUTION: An earth retaining wall is provided with an earth retaining wall 2 and a plurality of bearing parts 3 arranged from a rear surface of the earth retaining wall 2 so as to protrude in a rear direction and positioned in interval along a direction where the retaining wall 2 extends. A tie-rod 4 connects a rear end part of each of the bearing parts 3 and a center part of the earth retaining part 2 between adjacent bearing parts 3, 3. The earth retaining part 2 between the adjacent bearing parts 3, 3 is formed in a flat surface shape of an arch shape protrudingly expanding in a rear direction.SELECTED DRAWING: Figure 3
【課題】土留壁上端部の変位量を抑制して、所要の深さまで確実に掘削できるようにするとともに、土留壁背面の地盤変状を少なくし、土留壁構築のための工費・工期を低減する。【解決手段】土留部２と、前記土留部２の背面から後方に突出して設けられるとともに、前記土留部２が延びる方向に沿って間隔をあけて複数配置された支圧部３とを備えた土留壁である。前記支圧部３の後端部と、隣接する前記支圧部３、３の間における前記土留部２の中央部とがタイロッド４で連結されている。隣接する前記支圧部３、３の間における前記土留部２が、後方へ向けて膨出するアーチ形の平面形状で形成されている。【選択図】図３
