WATER INLET WITH FREEZING PREVENTIVE FUNCTION
PROBLEM TO BE SOLVED: To provide a water inlet with freezing preventive function capable of obtaining effective freezing preventive effect with a simple configuration.SOLUTION: A water inlet 1-1 is formed by covering an opening 13 for water intake formed on a river bottom 81 of a river 80 by a grating 15 with multiple open holes 15a. The water inlet 1-1 is prevented from freezing by installing an air vent pipe 19, which discharges air flowed into downstream (lower side) through the grating 15 during water intake, on the grating 15. The air vent pipe 19 is erected on the grating 15 and a lower end of the air vent pipe is fit to the grating 15 and an upper end opens in atmosphere above a water level of the river 80.SELECTED DRAWING: Figure 3
【課題】簡易な構成で、効果的な凍結防止効果が得られる凍結防止機能付き取水口を提供すること。【解決手段】河川８０の川底８１に形成された取水用の開口１３を複数の貫通孔１５ａを有するグレーチング１５で覆ってなる取水口１−１である。取水の際にグレーチング１５を通してその下流側（下側）に流入する空気を排出させるエア抜き管１９をグレーチング１５に取り付けることで、取水口１−１の凍結を防止する。エア抜き管１９は、グレーチング１５に立設し、その下端がグレーチング１５に取り付けられ、その上端が河川８０の水面上の大気中に開口している。【選択図】図３
