Energy dissipation method for river channel concave bank and scour prevention device thereof
The invention relates to the technical field of curve construction, in particular to an energy dissipation method for a river channel concave bank and an anti-scour device thereof.The method comprises the steps that in the field equipment installation stage, a plurality of anti-scour devices are arranged at a river channel curve in an array mode, and a pressure water level gauge and a flow velocity measuring device are installed at the upstream position of a river channel; entering a data analysis stage: establishing an analysis system, and judging data obtained by the pressure water level gauge and the flow velocity measuring device through the analysis system; determining working condition types and adjusting the running state of the anti-scour device: inputting a threshold value in an analysis system, dividing the working conditions into three types, namely a low-flow-speed working condition, a high-flow-speed working condition and a flood discharge working condition, and adjusting the running state of the anti-scour device according to one type. Therefore, effective energy dissipation and scour prevention effects are achieved on curves with different water levels, huge kinetic energy generated by water flow can be effectively weakened at various water levels, and the stability of a river channel and a riverbed is improved.
