中文摘要

本研究進行水槽試驗探討利用農塘豎井下緣出流孔及其加裝水平臥管的排淤效果。試驗在方形壓克力水槽進行,水槽內設有豎井,其底部設有排沙出流孔(豎井出流孔排沙)。此豎井出流孔可連接臥管,臥管上方有三個排沙出流孔(臥管出流孔排沙)。首先進行沒有淤沙情況的清水試驗,以瞭解水位與出流量之關係,然後進行沉滓為微細沙的排淤試驗,試驗有定水頭及變水頭兩種。試驗後量測排淤所形成的沖刷坑地形,用以分析不同排淤方式及相關條件對排淤量及排沙效率之影響。

英文摘要

This study investigated the desilting efficiencies of a pond by using both the shaft orifice of the pond and the horizontal pipe that was connected to the shaft orifice. The experiments were conducted in a square acrylic tank. The tank featured one vertical square shaft, and the shaft had a bottom orifice that could be used for removing sediment from the tank. The shaft orifice could be installed using a horizontal pipe with three circular orifices that allowed for sediment removal. Water-flow tests without sediment were first conducted to determine the relationship between water level and discharge through the orifices. Desilting experiments were then conducted using fine sands as the pond deposit under both constant head and falling head conditions. The final topographies of scour cones formed through water flushing were used to analyze the influence of desilting arrangements and related conditions on the volume of desilted sediment and desilting efficiency.
