To provide an aquatic plant removal device and an aquatic plant removal method capable of improving aquatic plant work efficiency by preventing water from clouding and interfering with visibility of a worker carrying out weeding work by diving when aquatic plant is removed from the bottom of a lake.SOLUTION: Compressed high pressure air from an air supply source 2 is guided in between vertical cylinder unit 10 and a water outflow member 17 from a communication port 16 through an air supply hose 3 and an air supply cylinder unit 12, rises along an air rising passage UP, and further rises up inside the vertical cylinder unit 10. A powerful water flow is created in the vertical cylinder unit 10 along with rising of high pressure air, water WA of a lake is guided to the vertical cylinder unit 10 through a horizontal cylinder unit 11 from a suction opening 11K, efficient rapid water flow is created in the water by the narrowed water outflow member 17, suction from the suction opening 11K is made stronger, the suction opening 11K sucks in a portion close to the root of a stem of the aquatic plant WP from the horizontal direction, and pulls out by sucking in the stem while bending it.SELECTED DRAWING: Figure 1

    【課題】湖沼の底から水草を除去する際に、水が濁らないようにして潜水して除草作業を行う作業員の視界を妨げないようにし、水草の作業効率の向上を図ることができる水草除去装置及び水草除去方法の提供。【解決手段】エアー供給源2からの圧縮された高圧空気はエアー供給ホース3、エアー供給筒部12を介して連通口16から垂直筒部10と水流出部材17との間に導入され、エアー上昇通路UPに沿って上昇し、更に垂直筒部10内を上昇する。高圧空気の上昇に伴い、垂直筒部10内に勢いのよい水流ができ、吸込み口11Kから湖沼の水WAは水平筒部11を経て垂直筒部10内へと導かれ、水は狭められた水流出部材17により効率の良い早い水流ができて、吸込み口11Kからの吸込みも強くなって、吸込み口11Kは水草WPの茎の根元に近い部分を水平方向から吸い込み、茎を折り曲げるようにしながら吸い込んで引き抜くことになる。【選択図】図1
