POLLUTION DIFFUSION SUPPRESSING DEVICE AND POLLUTION DIFFUSION SUPPRESSING METHOD OF PUMP DREDGER
PROBLEM TO BE SOLVED: To provide a pollution diffusion suppressing device and a pollution diffusion suppressing method of a pump dredger in which the diffusion of pollution in pump dredging can be suppressed by a simple structure.SOLUTION: A pump dredger includes a cutter head rotatably disposed in the tip end of a ladder 3 inserted underwater, a pipeline with a suction port opened at a ladder tip end, and a suction pump connected to the pipeline. A pollution diffusion suppressing device 20 includes a pollution suction port part 21 disposed in the tip side of the cutter head, a pollution suction pipe 22 for connecting the pollution suction port part 21 with the pipeline 6, and a flexible pollution receiving membrane 24 with a trapping side directed to the swing direction supported through a frame 23 for supporting the membrane in the pollution suction port part 21, in which the diffusion of the pollution caused by the excavation using the cutter head 5 is suppressed.SELECTED DRAWING: Figure 1
【課題】簡便な構造でポンプ浚渫における汚濁の拡散を抑制することができるポンプ浚渫船の汚濁拡散抑制装置及び汚濁拡散抑制方法の提供。【解決手段】水中に挿入されるラダー３先端部に回転可能に配置されたカッタヘッドと、ラダー先端部に吸引口を開口させた輸送管路と、輸送管路に接続された吸引ポンプとを備えたポンプ浚渫船にあって、カッタヘッドの先端側に配置された汚濁吸引口部２１と、汚濁吸引口部２１と輸送管路６とを結ぶ汚濁吸引管２２と、汚濁吸引口部２１に膜支持用フレーム２３を介して支持されたスイング方向に捕獲面を向けた可撓性を有する汚濁受け膜２４とを備え、カッタヘッド５による掘削で生じた汚濁の拡散を抑制するようにした汚濁拡散抑制装置２０。【選択図】図１
