DREDGING INTAKE STRUCTURE
PROBLEM TO BE SOLVED: To solve the problem that: in a dredging device for removing a predetermined thickness of mud and sand at a bottom of a pond or the like by sequentially sucking up mud and sand etc. at the bottom of the pond or the like by advancing a dredging intake structure, a suction pipe is clogged because it sucks in lumps of mud and elongated objects such as aquatic plants flowing in between fences of the dredging intake structure.MEANS FOR SOLVING THE PROBLEM: A dredging intake structure having a rotary cutter that prevents clogging of a suction pipe by crushing lumps of mud and elongated objects such as aquatic plants flowing in between fences with a rotary cutter, and the like are provided.SELECTED DRAWING: Figure 10
【課題】浚渫用取込口構造体を前進させることによって池等の底にある泥や砂などを順次吸い上げることで池等の底にある泥や砂を所定厚分除去する浚渫装置において、浚渫用取込口構造体柵の間から流入する水草等の細長いものや泥のかたまり等を吸い込んでしまうため吸込管が目詰まりするという問題が残されていた。【課題を解決するための手段】柵の間から流入する水草等の細長いものや泥のかたまり等を回転カッターで粉砕して吸込管の目詰まりを防ぐ回転カッターを有する浚渫用取込口構造体などを提供する。【選択図】図１０
