INSTALLATION STRUCTURE AND INSTALLATION METHOD OF RIVER INTAKE WORK
To provide a technique which is excellent in an effect for reducing dust, is also excellent in maintainability, enables addition on an existing head work, and dispenses with permission of a river manager.SOLUTION: A bottom face suction type water intake work (2) having a water intake opening (21) and a grating (23) on the bottom face side, and an intake (22) on the back face side as the downstream side is installed on a head work (1) having a fixed weir (11) for damming water and an inlet (12) for guiding water to an irrigation channel so as to have an interval from a river bottom (3), and then gabions (6) are installed on the upstream side of the bottom face suction type water intake work (2) and the river bottom (3) on the side face side.SELECTED DRAWING: Figure 1
【課題】塵芥を減らす効果に優れており、メンテナンス性にも優れ、既存の頭首工に対して増設することも可能で河川管理者の許可が不要な技術を提供する。【解決手段】 水を堰き止める固定堰（１１）と、水を用水路に導く取入口（１２）を有する頭首工（１）に、底面側に取水開口（２１）及びグレーチング（２３）有し、下流側となる背面側に取水口（２２）を有する底面吸込型取水工（２）を、川底（３）との間に間隔を有するように設置した後に、該底面吸込型取水工（２）の上流側及び側面側の川底（３）に、蛇籠（６）を設置する。【選択図】図１
