To provide an underwater object recovery method and a skeleton bucket used for this capable of recovering numerous underwater objects dispersedly existing underwater at high efficiency without breaking them as much as possible.SOLUTION: An underwater object recovery method includes: an object position specifying process for specifying object position of underwater objects 4 dispersedly existing on water bottom beforehand based on water depth value of the water bottom measured by a prescribed depth measuring means; a work barge moving process for moving a work barge 3 capable of raising/lowering a skeleton bucket 1 formed in a lattice state so that the underwater objects 4 do not fall near the object position; a bucket lowering process for lowering the skeleton bucket 1 over the underwater object 4 based on underwater image from an underwater image acquirement means 17 provided on the skeleton bucket 1; and a bucket raising process for raising the skeleton bucket 1 in a state where the skeleton bucket 1 is grasping the underwater object 4.SELECTED DRAWING: Figure 1

    【課題】 水底に点在する多数の水中物体をできるだけ壊すことなく高効率で回収することができる水中物体回収方法およびこれに用いるスケルトンバケットを提供する。【解決手段】 所定の測深手段によって測定された水底の水深値に基づいて、水底に点在する水中物体4の物体位置を予め特定する物体位置特定工程と、水中物体4が脱落しない格子状に形成されたスケルトンバケット1を昇降可能な作業船3を物体位置近傍に移動させる作業船移動工程と、スケルトンバケット1に設けられた水中映像取得手段17からの水中映像に基づいて、スケルトンバケット1を水中物体4上に降下させるバケット降下工程と、スケルトンバケット1が水中物体4を把持した状態で、スケルトンバケット1を上昇させるバケット上昇工程と、を有する。【選択図】 図1
