- ケーソンタイプの既設防波堤の前面壁または背面壁に沿って、断面で前後方向に非対称形状の増設ケーソンを海に浮いた状態にして配置し、該海に浮いた状態の増設ケーソンと既設防波堤との間に張設したワイヤを巻き取ることにより互いをガスケットを介在させて所定位置まで近接させ、該近接した増設ケーソンと既設防波堤とを連通する連結ボルトにより増設ケーソンを既設防波堤の前面壁または背面壁に連結するとともに、中詰材により所定の重量を付与してマウンド上に設置する既設防波堤の補強方法であって、前記増設ケーソンに断面前後方向に位置をずらして形成された上部を開口した複数の室に、バランス調節材を投入し、その際に投入されるバランス調節材の増設ケーソンの断面前後方向における重量の偏在具合を調節することにより、該増設ケーソンを断面前後方向で一定の状態に均衡させて海に浮いた状態にする既設防波堤の補強方法。
- 前記バランス調節材として比重の異なる2種類以上の材料を用いる請求項1に記載の既設防波堤の補強方法。
- 前記バランス調節材として海水あるいは水を用いる請求項1または2に記載の既設防波堤の補強方法。
