POLLUTION-PREVENTION STRUCTURE USED IN DREDGING WORK
PROBLEM TO BE SOLVED: To provide a pollution-prevention structure used in dredging works, which can securely show a drawing function and pollution-prevention function.SOLUTION: A pollution-prevention structure in this invention prevents pollution during dredge works by utilizing: a pollution-prevention frame arranged in front of a dredger; and an earth-carrying barge onto which dredged sediment is loaded, comprising: a traveling-block part arranged on a broadside of the earth-carrying barge; a fixed-block part arranged on the pollution- prevention frame; a winding device arranged on the dredger; and a traction member material which pulls the earth-carrying barge towards the dredger and the pollution-prevention frame. The traction member material has its rear end connected to the winding device, the middle part hooked on the traveling block and the fixed block, and the forward end connected to the earth-carrying barge.SELECTED DRAWING: Figure 2A
【課題】本発明は、引き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に使用される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、土運船の舷側に設けられた動滑車部と、汚濁防止枠に設けられた定滑車部と、浚渫船に設けられた巻取装置と、土運船を浚渫船側及び汚濁防止枠側へ牽引する牽引部材と、を備えており、牽引部材は、後端が巻取装置と連結され、中途部が動滑車部と、定滑車部へ掛けられ、先端が土運船と連結されている。【選択図】図２Ａ
