PROBLEM TO BE SOLVED: To provide an underwater transportation method capable of realizing a work safer than a conventional pressure-proof buoy.SOLUTION: An underwater transportation method of transporting an aluminum anode 200 by using a pressure-resistant container 100 equipped with a first on-off valve 20 and a second on-off valve 30 on the outer wall part is an underwater transportation method of transporting the pressure-resistant container 100 and the aluminum anode 200 to an underwater predetermined position in a coupled state to hook the aluminum anode at the predetermined position, and to vent air inside the pressure-resistant container and inject water into the pressure-resistant container by opening the first and second on-off valves 20, 30 for a predetermined period, thereby making a force of the pressure-resistant container to tend to float up smaller than before opening the first and second on-off valves 20, 30, and decoupling the water-injected pressure-resistant container 100 from the aluminum anode 200 to transport the decoupled pressure-resistant container 100 to a water surface.SELECTED DRAWING: Figure 3

    【課題】従来の耐圧ブイに比べてより安全な作業を実現出来る水中運搬方法を提供すること。【解決手段】外壁部に第1及び第2開閉バルブ20、30が設けられた耐圧容器100を用いてアルミ陽極200を水中で運搬する水中運搬方法であって、耐圧容器100とアルミ陽極200とを連結した状態で水中の所定位置まで運搬し、所定位置において、アルミ陽極を引っ掛け、第1及び第2開閉バルブ20、30を所定期間だけ開くことにより、耐圧容器の内部のエアーを抜くと共に耐圧容器の内部に注水し、耐圧容器による浮き上がろうとする力を第1及び第2開閉バルブ20、30を開く前よりも小さくし、注水された耐圧容器100とアルミ陽極200との連結を外し、連結が外された耐圧容器100を水面まで運搬する、ことを特徴とする水中運搬方法である。【選択図】図3
