To provide a cutoff device and a cutoff method capable of cutting off water in a canal even where no guide grooves on both of canal walls are installed, as well as facilitating workability even when cutoff members are subjected to buoyant force in water.SOLUTION: A cutoff device 1 is provided with: support poles 10a to 10c installed on a canal; a plurality of cutoff members 20a to 20f stacked on the canal; and assembling jigs 30a to 30c used upon stacking the cutoff members 20a to 20f. The assembling jigs 30a to 30c having holes formed in which the support poles 10a to 10c are inserted comprise: attachment part attached rotatably on the support poles 10a to 10c through the holes and movably in a longitudinal direction of the support poles 10a to 10c; and retaining plates retaining the cutoff members 20a to 20f through protruding directly or indirectly from the attachment parts.SELECTED DRAWING: Figure 1
【課題】水路の両壁にガイド溝がない箇所においても水路の遮水を可能にすることができるとともに、遮水材が水中で浮力を受けても作業性のよい遮水装置及び遮水方法を提供する。【解決手段】遮水装置１は、水路に設置される支持ポール１０ａ〜１０ｃと、水路に積層される複数の遮水材２０ａ〜２０ｆと、遮水材２０ａ〜２０ｆを積層する際に用いられる組立用治具３０ａ〜３０ｃと、を備える。組立用治具３０ａ〜３０ｃは、支持ポール１０ａ〜１０ｃが挿入される穴が形成され、穴を介して支持ポール１０ａ〜１０ｃに回転可能且つ支持ポール１０ａ〜１０ｃの長手方向に移動可能に取り付けられる取付部と、取付部から直接又は間接的に突出し、遮水材２０ａ〜２０ｆを押さえる押さえ板部を有する。【選択図】図１
