Water and soil loss prevention device for river bank vegetation recovery

Abstract

The invention discloses a water and soil loss prevention device for river bank vegetation recovery, which comprises an auxiliary drainage tank, a slope protection baffle block and a flushing reduction chamber, and is characterized in that the auxiliary drainage tank is arranged at the upper part of a river bank and can directly drain water at the upper part of the river bank into a river channel through a second drainage pipe; the first drainage pipe can be controlled through the electromagnetic valve to assist in drainage, the slope protection check block is arranged on the surface of the slope protection and plays a role in reducing the flowing speed of rainwater on the surface of the slope protection, the high-flow-speed water flow scouring resistance of the slope protection is improved, and the flushing reduction cavity is formed below the water surface and close to the bottom of the river bank; the flushing reducing cavity is of a cavity structure with the cross section being in a right trapezoid shape and one side open, and a first flow guide plate and a second flow guide plate are arranged in the flushing reducing cavity, so that water flow can be guided into the flushing reducing cavity, flushing of the water flow is reduced through the second flow guide plate, energy of the water flow is consumed, and the flow direction of river water is changed through generated elastic potential energy.

Description

technical field [0001] The invention relates to the technical field of vegetation restoration, in particular to a water-repellent soil loss device for riverbank vegetation restoration. Background technique [0002] Soil erosion refers to the whole process of soil being eroded, transported and deposited under the action of water flow. In the natural state, the surface erosion process purely caused by natural factors is very slow, and it is often in a relatively balanced state with the soil formation process. However, in the human Under the influence of activities, especially after humans have severely damaged the vegetation on the surface, the surface soil damage and the movement of land materials caused by natural factors will accelerate the loss process, that is, soil erosion occurs. Under the action of external forces, the damage and loss of water and soil resources and the main force of land production, including land surface corrosion and water loss; [0003] At present...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the measures taken to deal with water and soil erosion are to directly transplant saplings on the river bank for soil reinforcement to avoid water and soil erosion. However, the root system of the saplings is not developed enough to penetrate into the soil to a sufficient depth in a short time, resulting in a long period of time before transplanting. Within a short period of time, the water and soil loss situation cannot be significantly improved, and because the root system of the saplings is scattered in the soil near the surface, the main root grows slowly, which is easy to cause the saplings to fall, and the survival rate is low, while the transplanting of large trees is difficult, high cost, and low survival rate;
