Flood discharge type flow measuring weir
The invention discloses a flood discharge type flow measuring weir. Comprising a base rock, flood control dams arranged on the base rock side by side at intervals, a drainage dam arranged between the flood control dams, and a triangular weir arranged between the drainage dam and one of the flood control dams. The flow measuring facility is arranged on the drainage dam and located on the upstream of the triangular weir, the spillway dam is arranged between the drainage dam and the other flood control dam, the top face elevation of the spillway dam is the same as the top face elevation of the drainage dam, a drainage channel is formed between the drainage dam and one flood control dam, and the drainage channel is communicated with the flood control dam. A spillway is formed between the drainage dam and the other flood control dam; the combined weir integrating the triangular weir and the flood discharge weir formed by the spillway is adopted, and the tasks of monitoring the runoff flow and the flood flow of the small watershed are completed at the same time.
本发明公开了一种泄洪式测流堰，包括基岩、并排间隔设置在所述基岩上的防洪坝、设置在所述防洪坝之间的引流坝、设置在所述引流坝与其中一个所述防洪坝之间的三角堰、设置在所述引流坝上并位于所述三角堰上游的测流设施以及设置在所述引流坝与另一个所述防洪坝之间的溢洪坝，所述溢洪坝的顶面标高与所述引流坝的顶面标高相同，所述引流坝与其中一个所述防洪坝之间形成引流渠，所述引流坝与另一个所述防洪坝之间形成溢洪道；本发明采用三角堰和溢洪道形成的泄洪堰两位一体的组合堰，同时完成小流域径流流量和洪水流量的监测任务。
