POLLUTION PREVENTION STRUCTURE AND DRAWING DEVICE FOR DREDGING WORK
PROBLEM TO BE SOLVED: To provide an economically feasible pollution prevention structure for dredging work that performs a drawing function and a pollution prevention function for certain.SOLUTION: A pollution prevention frame disposed in front of a dredge ship constitutes a structure for preventing pollution from dredging work executed using a barge on which dredged sediment is loaded. A drawing device is provided on the pollution prevention frame, the drawing device including a fixing plate fixed on the pollution prevention frame so as to erect in a perpendicular direction to the pollution prevention frame, and an adsorptive part provided on the fixing plate and being movable in a horizontal direction. The adsorptive part includes a rod part inserted into a through-hole formed on the fixing plate and being movable in the horizontal direction, a connection plate connected to a tip of the rod part and movable in response to movement of the rod part in the horizontal direction, three or more caster parts provided on an outer peripheral surface of the connection plate on the barge side and being in contact with the barge, and a magnetic force generating part provided on the outer peripheral surface of the connection plate on the barge side and carrying a magnet of which a height is lower than the caster part.SELECTED DRAWING: Figure 2
【課題】本発明は、引寄せ機能と汚濁防止機能を確実に発揮でき、且つ経済的な浚渫作業用の汚濁防止構造を提供する。【解決手段】浚渫船の前方に配置された汚濁防止枠と、浚渫した土砂が積載される土運船を利用して施工される浚渫作業の汚濁を防止する構造であって、汚濁防止枠には引寄せ装置が設けられており、引寄せ装置は、汚濁防止枠に対して鉛直方向に起立する様態で固定された固定プレートと、該固定プレートに設けられた水平方向の移動が可能な吸着部とが設けられており、吸着部は、固定プレートに設けられた貫通孔に挿通され、且つ水平方向の移動が可能なロッド部と、ロッド部の先端に接続され、ロッド部の水平方向の移動に応じて移動可能な連結板と、連結板の土運船側の外周面に設けられ、且つ土運船と当接される３個以上のキャスター部と、連結板の土運船側の外周面に設けられ、キャスター部より低い高さを有する磁石を搭載した磁力発生部と、を有している。【選択図】図２
