A kind of waterproof soil loss device for riparian vegetation restoration

Abstract

The invention discloses a soil loss prevention device for river bank vegetation restoration, which comprises an auxiliary drainage pool, a slope protection block and a flush-reducing chamber. The auxiliary drainage pool is arranged on the upper part of the river bank, and the water body on the upper part of the river bank can be directly drained through a second drainage pipe. When the drainage volume of the second drainage pipe is insufficient, the first drainage pipe can be controlled by the solenoid valve for auxiliary drainage. The slope protection block is arranged on the slope protection surface to slow down the flow speed of rainwater on the slope protection surface. , which improves the resistance of the slope protection to the scour of high-velocity water flow. Below the water surface and near the bottom of the river bank, there is a scour reduction chamber. There is a first deflector and a second deflector, so that the water flow can be guided into the de-flushing chamber, and then the second deflector is used to reduce the flushing, which consumes the energy of the water flow and utilizes the generated elastic potential energy. to change the flow of the river.

Description

Technical field [0001] The invention involves the field of vegetation recovery technology, and is specifically for a waterproof device for waterproof soil -proof waterproofing. Background technique [0002] Water and soil loss refers to the entire process of erosion, handling and precipitation under the influence of water flow. In the natural state, the surface erosion process of pure natural factors is very slow, often in a relatively balanced state with soil formation, but in humans Under the influence of the activity, especially after human beings severely destroyed the vegetation on the surface, the ground soil destruction and land material movement caused by natural factors accelerated, that is, the loss of soil and soil, the water and soil loss refers to the water, gravity, wind speed, etc. Under the action of external forces, the damage and losses of the main force of water and soil resources and land production, including the surface corrosion of the land and the loss of ...

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;
