FOUNDATION REINFORCEMENT METHOD, AND STRUCTURE
To provide a foundation reinforcement method and a structure capable of making am embedment depth of a foundation shallow.SOLUTION: A monopile 1 of an ocean wind power generation facility 5 is installed on a water bottom ground 3. Cooling liquid is circulated in a freezing pipe in a vertical direction and a freezing pipe in a horizontal direction disposed inside the monopile 1, to freeze the ground 3 around the monopile 1. The freezing pipe is disposed so that cooling power near a surface layer 15 of the ground 3 becomes larger than that in other parts. By freezing the ground 3 around the monopile 1 to increase friction force between the monopile 1 and the ground 3, a resistance to a horizontal force can be secured even if an embedment depth of the monopile 1 is shallow, compared with the non-freezing case.SELECTED DRAWING: Figure 1
【課題】基礎の根入れ深さを浅くすることができる基礎の補強方法および構造物を提供する。【解決手段】水底の地盤３に洋上風力発電設備５のモノパイル１を設置する。そして、モノパイル１の内側に配置された鉛直方向の凍結管、水平方向の凍結管に冷却液を循環させて、モノパイル１の周囲の地盤３を凍結する。凍結管は、地盤３の表層１５付近の冷却能力が他の部分よりも大きくなるように配置される。モノパイル１の周囲の地盤３を凍結してモノパイル１と地盤３との摩擦力を増大させることで、凍結しない場合と比較してモノパイル１の根入れ深さが浅くても水平力に対する抵抗力を確保することができる。【選択図】図１
