我国最早的量水建筑物,据考证是1929年建于杭州九溪理安寺旁侧小溪上的三角堰,此量水堰为90°宽缘三角堰,钢筋混凝土结构,量水堰有效水头约1米。过去一直认为我国50年代才开始修建,使用量水建筑物,杭州九溪理安寺三角堰资料最近被发现,说明早在20年代末,我国已有量水建筑物,时间提前了20多年。
The earliest water volume building in our country is based on textual research that is a triangular weir built on the side stream of Li’an Temple in Jiuxi in Hangzhou in 1929. The weir is a 90 ° wide margin triangular weir with reinforced concrete structure and effective weir head About 1 meter. In the past, it was thought that in the 1950s China started to construct and use water and water structures. The data on the triangular cofferdam of Li’an Temple in Jiuxi in Hangzhou was recently discovered, indicating that as early as the late 1920s, the amount of water and water structures in our country was up to 20 years ahead of time.
