Hydraulic flow measuring groove suitable for natural river channel
The invention discloses a hydraulic flow measuring groove suitable for a natural river channel. The hydraulic flow measuring groove comprises a large groove bottom plate arranged on a riverbed betweenrevetments on the two sides of the natural river channel in the downstream direction, wherein drainage holes are evenly distributed in the large groove bottom plate; a flow measuring groove body is formed in the large groove bottom plate in the downstream direction; and the flow measuring groove body is sequentially composed of a contraction energy dissipation section, a throat straight section,a diffusion energy dissipation section and an anti-scour section in the downstream direction. The hydraulic flow measuring groove solves the problems that a mountainous river rises and falls suddenly,the river channel gradient is large, and the flow speed is large; and multiple testing manners are combined for use, the flow testing precision is guaranteed, and a testing section which is regular,stable and capable of being used once and for all is created.
本发明公开了一种适于天然河道的水工测流槽，包括沿顺水流方向设置在天然河道两侧护岸之间河床上的大槽底板，所述大槽底板上均布开设有排水孔，大槽底板上沿顺水流方向开设有测流槽，所述测流槽沿顺水流方向依次由收缩消能段、喉道顺直段、扩散消能段和防冲段构成。本发明解决了山区性河流暴涨暴落、河道比降大和流速大等难题，采用多种测验方式结合使用，保证流量测验精度，创造一个规则性、稳定性、一劳永逸的测验断面。
