<p>PROBLEM TO BE SOLVED: To provide a banking reinforcement structure capable of reducing cost, while expecting the sufficient earthquake time banking settlement restraining effect and the water-overflowing time bank breaking restraining effect, even to a ground condition of deeply positioning a support layer.SOLUTION: A steel sheet pile wall 3 is provided in the continuous direction of banking 1 in a slope shoulder part 1c of the continuous banking 1, and is embedded up to the shallower depth than a support layer 4, and a steel support material 10 embedded up to the support layer 4 in a slope tail part 1d of the banking 1, is discretely arranged at a predetermined interval in the continuous direction of the banking 1, and a steel sheet pile wall 3 and the respective steel support materials 10 are respectively joined by a first connection material 11, and thereby, the steel sheet pile wall 3 is supported by the steel support material 10 via the first connection material 11, so that the sufficient earthquake time baking settlement restraining effect and the water-overflowing time bank breaking restraining effect can be expected even to a ground condition of deeply positioning the support layer 4, and cost can be reduced while maintaining the effects.</p> |
