性確保ζこ関するものである。[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a method for installing caisson in the construction of offshore structures using caisson such as seawall construction and breakwater construction, especially caisson installation which is a problem in caisson construction. This is related to ensuring stability immediately after.
ケーソンを用いた海洋構造物の施工において、ケーソン
を所定の位置に沈設した直後の状態は、風、波浪などの
外力が作用するため非常に不安定である。In the construction of offshore structures using caisson, the state immediately after the caisson is sunk in a predetermined position is extremely unstable due to the action of external forces such as wind and waves.
このため従来の技術では中詰砂の充填を急速に行なうこ
とにより、ケーソン自体の重量を増加させ、この重量に
よる摩擦力で外力に抵抗させることが行なわれている。For this reason, in the prior art, the weight of the caisson itself is increased by rapidly filling the caisson with sand, and the frictional force generated by this weight is used to resist external forces.
しかし、中詰砂の充填については規模が大きくなればな
る程、砂の量が多くなり、急速に充填することが難しく
なる。However, when it comes to filling with sand, the larger the scale, the larger the amount of sand, and the more difficult it becomes to fill it quickly.
そこで、この発明では沈設したケーソン上にウェイトセ
ルを仮置し、この中に海水等の水を注入することによっ
て所要重量を確保し、施工時の安定を図っている。Therefore, in this invention, a weight cell is temporarily placed on top of the sunken caisson, and water such as seawater is injected into the cell to ensure the required weight and to ensure stability during construction.

It is also possible to connect a plurality of pieces and use them as one unit.

となり、内部に注入した水を排出し、次のケーソン据付
のために移動させる。During construction, the above-mentioned weight cell is placed on top of a caisson that has been sunk in a predetermined position, and water such as seawater is injected into the tank of the weight cell to secure the electric resistance welding of the weight cell, and this weight is used to resist external forces. let In this way, the caisson is stabilized at an early stage, and in a stable state, the caisson is filled with filling sand or the like. Filling of the caisson and necessary water drainage are carried out through the through holes of the weight cells mentioned above. Once the filling is complete, the weight cell will no longer be needed, and the water injected into it will be drained and moved for the next caisson installation.
