AI Technical Summary
When the prior art controls erosion channels, plant planting is unstable and it is difficult to play a role in seizing sand and intercepting the flow.
A U-shaped erosion channel management device was designed, including a steel wire mesh permeable layer, planted trees, reinforced concrete layers and overflow ports. The steel wire mesh permeable layer and reinforced concrete layer jointly intercept sediment and moisture, providing soil and moisture for planted trees, and overflow ports are used to discharge excess water.
The device can effectively intercept silt, prevent the channel from being cut down, collect the channel water to provide moisture for plant growth, and form a U-shaped platform over time, increase the cultivation area, and play the role of a silt dam. When a tree grows up, it can intercept silt and sand, retention and filtration water, and can become a firewood, charcoal forest and timber forest.

Abstract
Description
Technical Field
[0001] The utility model relates to the treatment of soil and water loss, in particular to a U-shaped erosion gully treatment device which has the functions of intercepting sediment and retaining flood and filtering water, and can become a fuelwood forest and a timber forest. Background Art
[0002] Gentle and long ground slopes and steep slopes are the topographic conditions for the formation of erosion gullies. In areas with gentle and long ground slopes, the catchment area is relatively concentrated, and the water flow is large. After entering the low-lying ground, it is washed by rainwater and accumulated water, gradually forming rills or shallow gullies. After years of erosion, gullies are gradually formed, and the gullies continue to develop to form erosion gullies.
[0003] Erosion gullies mainly develop on loose sediment layers in semi-arid climate zones. In gently sloping areas with sparse vegetation, erosion gullies can develop very quickly, strongly dividing the terrain, encroaching on cultivated land, damaging roads, and causing a large amount of soil and water loss. This not only causes a decrease in grain yield, but also threatens the property safety of residents and weakens the flood discharge capacity of river channels.
[0004] At present, the methods for treating erosion gullies mainly use building materials with strong erosion resistance such as stones, concrete, and wire cages to forcibly lock the gully head, stabilize the gully bank, and raise the erosion base level of the gully. Then, the self-soil-fixing ability of plants is used to stabilize the gully. However, in actual operation, it is difficult to fix the plants after planting, and they are easily washed away by water, making it difficult to play the role of sand fixation and interception of water flow. Summary of the Invention
[0005] The problem to be solved by the utility model is that in the current process of treating erosion gullies, the plants are not firmly planted and it is difficult to play the role of sand fixation and interception of water flow. The utility model provides a U-shaped erosion gully treatment device which has the functions of intercepting sediment and retaining flood and filtering water, and can become a fuelwood forest and a timber forest.
[0006] The U-shaped erosion gully treatment device of the utility model is installed perpendicular to the direction of the erosion gully incision. It is characterized in that the treatment device is arranged in a U shape, and includes a wire mesh permeable layer, planted arbors, a reinforced concrete layer, and overflow ports. The wire mesh permeable layer is arranged on the inner layer, the reinforced concrete layer is arranged on the outer layer, the planted arbors are arranged between the wire mesh permeable layer and the reinforced concrete layer, and the overflow ports are arranged at both ends.
[0007] At least one layer of the treatment device is provided, and at least one treatment device is provided in each layer; when two or more layers of treatment devices are provided, the adjacent two layers are arranged at equal intervals; when two or more treatment devices are provided in each layer, the overflow port at the tail end of the first one is connected to the overflow port at the head end of the second one.
[0008] The U-shaped treatment device can dissipate the energy of the confluence of a large flow rate; at the same time, using the wire mesh permeable layer can not only intercept large gravels, but also allow sediment and water to pass through. The sediment and water are blocked by the reinforced concrete layer, providing soil and water for the planted trees in the middle. The excess water can flow out from the overflow ports at both ends of the treatment device; over time, when the sediment at the reinforced concrete layer is full, a U-shaped platform can be formed, which not only increases the cultivated area and functions as a sediment retention dam, but also when the trees grow up, they can not only intercept sediment and detain and filter flood water, but also become fuelwood forests, timber forests, etc.
[0009] The U-shaped erosion gully treatment device of the present utility model has a reasonable structure, scientific design, and convenient use. The prefabricated treatment device can be directly placed into the erosion gully for use. It can be freely combined with multiple modules according to the actual size of the erosion gully. The U-shaped structure can dissipate the energy of a large flow of water. At the same time, sediment is intercepted by this device to prevent the gully from incising downward, and the collected gully water can provide water for plant growth.

[0013] Embodiment 1: A U-shaped erosion gully treatment device is installed perpendicular to the direction of the erosion gully incision.

The wire mesh permeable layer is arranged on the inner layer, the reinforced concrete layer is arranged on the outer layer, the planted tree is arranged between the wire mesh permeable layer and the reinforced concrete layer. It is preferably that the diameter of the planted tree is 2-3 cm, and the overflow ports are arranged at both ends.
[0014] At least one layer of treatment device is provided, and at least one treatment device is provided in each layer; when two or more layers of treatment devices are provided, the adjacent two layers are arranged at equal intervals; when two or more treatment devices are provided in each layer, the overflow port at the tail end of the first one is connected to the overflow port at the head end of the second one.
[0015] The U-shaped treatment device can dissipate energy for the confluence of a large flow rate; at the same time, by using the wire mesh permeable layer, it can not only intercept large gravels, but also allow sediment and water to pass through. The sediment and water are blocked by the reinforced concrete layer, providing soil and water for the planted trees in the middle. The excess water can flow out from the overflow ports at both ends of the treatment device; over time, after the sediment at the reinforced concrete layer is filled up, a U-shaped platform can be formed, which not only increases the cultivated area and functions as a check dam, but also, after the trees grow up, can not only intercept sediment and detain and filter floodwater, but also serve as a fuelwood forest, a timber forest, etc.
