To provide a technology capable of preventing a sludge from rising upward in a movement of a dredging structure, to solve a problem that it is difficult for some conventional dredging devices to silently scoop up only the surface of a water bottom in a pond and the like to be decontaminated and that the sludge is raised upward in movement, in a context that the most attention must be paid not to spread the sludge settling on the water bottom, in recovering the sludge in the water bottom.SOLUTION: An intake port structure for dredging comprises: a top face; a back face; a side face; an intake port; an opening; a fence for preventing entry of a matter with a size clogging the intake port into the intake port; a shaft for movement; and an eave that is extended forward from a substantially front edge of the top face and that sucks turbidity raised upward in a water bottom.SELECTED DRAWING: Figure 1
【課題】水底の汚泥を回収する場合において最も注意を払うべきは、水底において鎮静化している汚泥を水中に拡散させてしまうことのないよう行わことである。従来型の渫機によっては除染すべき池等の水底の表面のみを静かにすくい取ることが困難であり、移動の際に汚泥が巻き上がってしまうことがあるという問題があった。そのため,浚渫構造体の移動において汚泥が巻き上がってしまうことを防止できるような技術が望まれていた。【解決手段】上面と、背面と、側面と、取込口と、開口と、取込口が詰まるサイズの物を取込口に入れないための柵と、移動用シャフトと、前記上面略前端から前方に張り出した水底で巻き上げられる濁りを吸い取るための庇を有する浚渫用取込口構造体を提供する。【選択図】図1
