INTRUSION PREVENTION TOOL, AND INTRUSION PREVENTION STRUCTURE
To provide an intrusion prevention tool which can properly suppress clogging due to water plant etc. while properly suppressing intrusion of aquatic life such as apple snails into a water inlet.SOLUTION: An intrusion prevention tool 10 attached to a water inlet of an irrigation channel to be used and suppressing intrusion of aquatic life comprises: a first net body 50 disposed at the irrigation channel side of the water inlet and having a plurality of holes 52; and a second net body 60 disposed at an inner part side of the water inlet with an interval between itself and the first net body 50 in a flow passage direction and having a plurality of holes 62. The first net body 50 includes an opening larger than the hole 52. The hole 52 faces a bottom side of the irrigation channel.SELECTED DRAWING: Figure 2
【課題】スクミリンゴガイ等の水生生物の取水口への侵入を好適に抑制しつつ、水草等による目詰まりも好適に抑制可能な侵入防止具を提供する。【解決手段】用水路の取水口に取り付けられて用いられ、水生生物の侵入を抑制する侵入防止具１０であって、取水口の用水路側に配置される、複数の孔５２を有する第１網体５０と、取水口の内部側において第１網体５０と流路方向に間隔を開けて配置される、複数の孔６２を有する第２網体６０と、を備える。第１網体５０には、孔５２よりも大きい開口を備え、その孔５２は、用水路の底側を向いている。【選択図】図２
