などは、FRP樹脂部分の裁断中あるいは終了後
に前記剪断機１２を使用して適宜剪断処理する。 In the attached drawings, the method for disposing of FRP structures according to the present invention is as follows: First, a ship 10 to be disposed of made of FRP resin or the like is lifted to a dry dock or a disposal yard and fixed by an appropriate means, and then a shearer 1
Water jet nozzle 14 attached to the tip of 2
The FRP resin portion of the ship 10 to be disposed of is appropriately cut by injecting water jet water set at a pressure of, for example, 1000 Kg/cm 2 to 3000 Kg/cm 2 through the FRP resin portion. At this time, the steel material and the like as the frame material of the ship 10 to be scrapped are appropriately sheared using the shearing machine 12 during or after cutting the FRP resin portion.
また、FRP樹脂成分の裁断時および骨組材の
剪断時などに適宜の研磨材（アブレツシブル材）
