Earth retaining structures

Abstract

To propose an earth-retaining structure capable of suppressing deformation due to excavation of the ground on slopes where closed ring beams cannot be formed, and a construction method of this earth-retaining structure.SOLUTION: An earth-retaining structure 1 formed by excavating the ground including an inclined plane includes a curved part 4 having an arc shape in a plan view, a U-shaped beam 2 having a U-shape in a plan view and including a pair of straight parts 5, 5 extending from both ends of the curved part 4 and an earth-retaining wall 3 connected to the lower side of the U-shaped beam 2, the U-shaped beam 2 is fixed to the ground by a sewn member 6 driven into the ground and the earth-retaining wall 3 is formed along the ground surface exposed by excavating the area surrounded by the U-shaped beam 2.SELECTED DRAWING: Figure 1
