摘要

PROBLEM TO BE SOLVED: To provide a wharf wall reinforcement structure and a wharf reinforcement method that achieve construction on various wharves at low costs.SOLUTION: After a steel pipe pile 10 provided with a plurality of slit opening parts is embedded in an array along a wharf 1 and the slit opening parts are pressed from inside the pile material to be spread, a solidification material 20 is pressed and charged in the steel pipe pile 10 to form a projection part 10a at a part of the steel pipe pile 10 to be embedded in a sea bottom and on a sea-side foundation on the opposite surface side from the wharf. A foundation G1 on a front side (sea side) of the embedment part of the steel pipe pile 10 is reinforced by compaction with a plurality of projection parts 10a formed on the front of the steel pipe pile 10, and a foundation G1 on a back side (wharf 1 side) is also reinforced by compaction.
