PROBLEM TO BE SOLVED: To install a caisson by charging filling material to inner space of the caisson without leakage of water in the inner space of the caisson to outer section of the caisson, which contains substance derived from the filling material.SOLUTION: There is provided an installation method for a caisson, where a caisson 10 having an upper opening, which floats on water surface 82, is installed on water bottom 84. The method comprises: a landing step where water 14 is charged to an inner space 12 of the caisson 10 so as to land the caisson 10 on the water bottom 84 so that the caisson 10 is sunk until reaching the water bottom 84; and a filling material charge step where filling material 16 is charged to the inner space 12 of the caisson 10 landed on the water bottom 84 in the landing step. The height position of upper end of the caisson 10 landed on the water bottom 84 in the landing step is sufficiently higher than the height position of water surface 82 and water 14 charged to the inner space 12 of the caisson 10 in the landing step never leaks to outer section of the caisson 10 when charging the filling material 16 to the inner space 12 of the caisson 10 in the filling material charge step.SELECTED DRAWING: Figure 4
【課題】中詰め材に由来する物質が含まれるケーソンの内部空間の水を当該ケーソンの外部に流出させずに当該ケーソンの内部空間へ中詰め材を投入してケーソンを沈設する。【解決手段】水面８２に浮かぶ上方が開口したケーソン１０を水底８４に沈設するケーソンの沈設方法であって、ケーソン１０が水底８４に着底するようにケーソン１０の内部空間１２に水１４を投入して、ケーソン１０を水底８４に着底するまで沈降させる着底工程と、前記着底工程で水底８４に着底したケーソン１０の内部空間１２に中詰め材１６を投入する中詰め材投入工程と、を有し、前記着底工程で水底８４に着底したケーソン１０の上端部の高さ位置は水面８２の高さ位置よりも十分に高く、かつ、前記着底工程でケーソン１０の内部空間１２に投入された水１４は、前記中詰め材投入工程で中詰め材１６をケーソン１０の内部空間１２に投入した際、ケーソン１０の外部へ流出しない。【選択図】図４
