技術說明

台灣河川坡陡流急且具洪枯懸殊間歇性特性，颱洪變量流期間上水過程，河道劇烈下降存在短期一般沖刷現象，常危及橋基、橋墩、堤防、固床工等跨河水工構造物之安全性，故針對本土性河道進行颱洪調查甚具必要性。 本發明專利係研發一高效率沖刷磚柱埋設技術，藉以監測最大一般沖刷深度。利用長5 m輔助鋼棒，可迅速而安全地同時由河床面垂直向下埋設約93塊磚塊）之沖刷磚柱，藉以監測颱洪河道不平衡輸砂過程，洪峰附近之河道最大短期一般沖刷深度。 Most rivers in Taiwan are intermittent rivers. A short-term general scour usually occurs in the river during the rising limb of a flood due to the transitory sediment imbalance and the steep slope gradient. The short-term general scour cannot be neglected as it has caused many casualties in Taiwan such as bridge and embankment failures. A high efficient scour brick column laying technology was developed, which uses a 5 m long supplementary hollow steel rod with openings at both ends and two excavators. Based on the safety device, the excavators can simultaneously and quickly place about 93 pieces of numbered bricks at a time. The laying work was performed near one side of the main channel during the low flow period. After a flood, the riverbed was excavated to measure the short-term maximum general scour depth in the river reach.
