To provide a dredge device allowing excavation/removal operation of accumulated sedimentary soil to be efficiently performed as suppressing affect on the environment as low as possible even when obstacles such as sunken logs are mixed in the accumulated sedimentary soil accumulated in rivers, ports, dams, lakes, and the like.SOLUTION: A dredge 1 for dredging accumulated sedimentary soil accumulated on a water bottom where obstacles such as sunken logs are mixed as descending underwater is provided with: a casing 10; an underwater pump 11 accommodated inside of the casing 10 to suck/discharge the accumulated sedimentary soil; and at least one sucking pipe 13 having a tip part 13a arranged with an opening part 13b, and formed thinner than the casing 10 as well as extending downward from the casing 10, wherein the tip part 13a penetrates between the obstacles and pushes away the obstacles to suck the accumulated sedimentary soil from the opening part 13b.SELECTED DRAWING: Figure 2
【課題】河川、港湾、ダム、湖沼等に堆積した堆積土砂中に沈木等の障害物が混在していても、環境に及ぼす影響を少なく抑えつつ、効率良く堆積土砂の掘削・除去作業ができる浚渫装置を提供する。【解決手段】浚渫装置１は、沈木等の障害物が混在し、水底に堆積した堆積土砂を、水中を下降しながら浚渫するための浚渫装置１であって、ケーシング１０と、ケーシング１０の内部に収容され、前記堆積土砂を吸引・排出するための水中ポンプ１１と、開口部１３ｂが設けられた先端部１３ａを有し、ケーシング１０よりも細く形成されるとともに、ケーシング１０から下方に延びる少なくとも１の吸引管１３と、を備え、先端部１３ａは、前記障害物の間に入り込み且つ前記障害物を押し退けながら開口部１３ｂから前記堆積土砂を吸引する。【選択図】図２
