The working principle of the invention is as follows:
because the river potential is limited by boundary condition change in space change and is influenced by incoming water and sand change in time, the invention adopts the permeable guide plate with changeable angle, guides changeable water flow in a mode of combining multi-plate change with multi-unit change live-action simulation, combines side scouring change, adjusts the guide angle and dynamically coordinates water flow.
(1) Stabilization of river potential
The invention utilizes the principle of conservation of classical hydraulic energy to change the transmission of mv vector fields of water bodies with control and guide positions, regulate and control the exchange power of water and soil bodies on the downstream side, prevent collapse and damage and maintain the expected river potential of the interval.
The river channel and river potential wander change is completed by the combined action of the river channel runoff process (Q, t), the water flow direction and the river bed characteristics. The control flow influences the action of water flow on the river by changing the action direction of water flow, diversion or flow field redistribution, so that the river is developed towards the stable direction of the side of the favorable area. The included angle between the conventional control guide and the river potential is fixed. The angle between the direction-variable flow-control flow and the water flow is adjusted, the water flow is dynamically controlled, the variable runoff process can be better coordinated with the required river, and the most favorable working condition application can be obtained through a real-scene simulation test.
(2) Control and guide part
Structural shunt weak change: steel-pipe pile permeates water, the guide plate permeates water, all can divide and reduce the flow of choosing of incoming flow, forms certain weak rivers district simultaneously in the limit district, weakens and controls near bank and stake position backward flow and vortex intensity, stabilizes the limit and flows, keeps controlling near bank riverbed and changes to siltation by the scour.
Traditional river channel control and guide technology changes the direction of the water flow near the shore through a rigid structure fixed on the river beach. The relative position of the control guide and the river bank is fixed and unchangeable, and the influence is unchangeable. The invention uses the novel movable guide plate with the multifunctional movable sheet pile for picking and stabilizing the flow, dynamically adjusts the flow according to the change conditions of different periods of the river by changing the included angle between the water flow and the guide plate, is flexible and changeable for the incoming flow direction, and can adapt to the different flow rates of the water flow and the change requirements of the river. Compared with the common control and guide technology, the method has various operational schemes for adjusting the evolution of the river potential, changes the single adaptability of the traditional control and guide engineering to the water flow, and solves the problem of asymmetry of single action and complex river change condition of the traditional control and guide engineering. The invention also has reversibility, the main guide plate can be received and arranged, the forced interference to the river is less, and the ecological environment along the river can be better protected.
It should be noted that, in the description of the present invention, terms such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element to be referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention.
