Description

Technical Field

[0001] This utility model relates to the field of governance structure technology, and in particular to a governance structure for erosion gully heads. Background Technology

[0002] Erosion gullies, also known as water erosion gullies, are narrow, deep, and steep grooves formed by the long-term action of water flow on the soil surface. They typically occur on slopes or in low-lying areas, and are commonly found on the outskirts of agriculture, forestry, or cities, especially in areas with poor soil and water conservation or insufficient vegetation cover.

[0003] In existing technologies, traditional gully control structures often encounter situations where water flows from upstream, accompanied by large amounts of sediment. This directly exacerbates erosion at the gully head and indirectly leads to potential landslides at the gully head. Furthermore, some existing gully control structures prevent soil loss by silting up upstream water. However, this artificial silting not only fails to achieve good control results but also creates new gully erosion and indirectly increases costs significantly. Utility Model Content

[0004] The purpose of this invention is to provide a gully head treatment structure that can solve the problem that traditional gully treatment structures often encounter a large amount of silt flowing into the gully when dealing with upstream water flow. This avoids the problem that silt will exacerbate the erosion of the gully head and prevents potential landslides at the gully head. It also solves the problem that some gully treatment structures, when encountering upstream water flow, usually prevent soil loss by silting up. However, artificial silting not only fails to achieve good treatment results but also creates new gully erosion. This invention avoids the problem of a significant increase in treatment costs due to the increase in gullies.

[0005] To achieve the above objectives, a gully head management structure is provided, including an gully head body, a first vegetation planting area on the left side of the gully head body, and a second vegetation planting area on the right side of the gully head body.

[0006] A water interception ditch is provided on one side of the erosion ditch head body, and a sedimentation basin is provided on the other side of the water interception ditch. A stepped structure is provided on the other side of the sedimentation basin.

[0007] According to the aforementioned gully head treatment structure, the sedimentation basin is higher than the last step of the stepped structure, and a sand storage trough is provided on the upper surface of the sedimentation basin.

[0008] According to the aforementioned erosion gully head treatment structure, a first diversion channel is connected to the side of the intercepting ditch, and a second vegetation planting area is connected to the other end of the first diversion channel.

[0009] According to the aforementioned gully head treatment structure, a second diversion channel is provided on the left side of the first diversion channel, and one end of the second diversion channel is connected to a second vegetation planting area.

[0010] According to the aforementioned gully head treatment structure, a third diversion channel is provided on the left side of the second diversion channel, and one end of the third diversion channel is connected to a first vegetation planting area.

[0011] According to the aforementioned gully head treatment structure, a fourth diversion channel is provided on the left side of the third diversion channel, and one end of the fourth diversion channel is connected to the first vegetation planting area.

[0012] According to the aforementioned gully head treatment structure, the surface of the gully head body is provided with a rock slope protection, and the surface of the rock slope protection is provided with a protective net.

[0013] This utility model has the following beneficial effects:

[0014] 1. Compared with existing technologies, this gully head management structure, through the installation of a stepped structure and sedimentation basins, achieves a sustained and effective reduction of soil erosion at the gully head over the long term, lowering the cost of relying on manual intervention and maintenance. Furthermore, the sedimentation basins help protect and restore the ecological environment affected by soil erosion. By reducing sediment input, the sedimentation basins provide better growth conditions for plants and other ecological elements, promoting ecological restoration and thus preventing sediment from exacerbating gully head erosion and avoiding potential landslides at the gully head.

[0015] 2. Compared with existing technologies, this gully head management structure, through the installation of rock revetment and protective netting, effectively increases the slope's resistance to external forces, preventing slope collapse caused by water flow. The protective netting effectively stabilizes the slope soil, preventing further erosion. Furthermore, the protective netting enhances slope stability, preventing slope collapse caused by water impact, thus avoiding the significant increase in management costs associated with increasing gullies.

Detailed Implementation

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-3 This utility model embodiment provides a gully head treatment structure, which includes an gully head body 1, a first vegetation planting area 2 on the left side of the gully head body 1, a second vegetation planting area 3 on the right side of the gully head body 1, a rock slope protection 12 on the surface of the gully head body 1, and a protective net 13 on the surface of the rock slope protection 12.

[0025] A water interception ditch 4 is provided on the side of the erosion ditch head body 1. A sedimentation tank 5 is provided on the other side of the water interception ditch 4. A stepped structure 6 is provided on the other side of the sedimentation tank 5. The sedimentation tank 5 is higher than the last step of the stepped structure 6. A sand storage trough 7 is opened on the upper surface of the sedimentation tank 5. A first diversion channel 8 is connected to the side of the water interception ditch 4. A second vegetation planting area 3 is connected to the other end of the first diversion channel 8. A second diversion channel 9 is provided to the left of the first diversion channel 8. A second vegetation planting area 3 is connected to one end of the second diversion channel 9. A third diversion channel 10 is provided to the left of the second diversion channel 9. A first vegetation planting area 2 is connected to one end of the third diversion channel 10. A fourth diversion channel 11 is provided to the left of the third diversion channel 10. A first vegetation planting area 2 is connected to one end of the fourth diversion channel 11.

[0026] The aforementioned structure, through the inclusion of a stepped structure 6 and a sedimentation tank 5, ensures that when upstream water needs treatment, the water first flows through the stepped structure 6. The stepped structure 6 gradually disperses the water flow into multiple smaller areas, preventing water from concentrating at a single location and thus reducing erosion at that location. The stepped structure 6, by segmenting multiple steps, effectively reduces the water flow velocity. As the water flows through each step, its potential energy is gradually dispersed, weakening the impact and reducing the erosive effect on the soil. Compared to traditional soil and water conservation measures, the stepped structure 6 can continuously and effectively reduce soil erosion in the long term, lowering the cost of relying on manual intervention and maintenance. When upstream water carries a large amount of sediment downstream, the sedimentation tank 5 effectively intercepts these solid particles, reducing the amount of sediment carried by the water flow and thus mitigating soil erosion in the downstream area. The sedimentation tank 5 effectively removes suspended solids from the water, improving water quality. When facing upstream water flow, the sediment and pollutants brought by the flow degrade water quality. The sedimentation effect of sedimentation pond 5 can remove suspended particulate matter from the water, reduce water pollution, and improve the water quality of downstream water sources. Sedimentation pond 5 helps protect and restore the ecological environment affected by soil erosion. By reducing the input of sediment, sedimentation pond 5 provides better growth conditions for plants and other ecological elements, promoting ecological restoration. The maintenance of sedimentation pond 5 is relatively simple, mainly involving regular cleaning of deposited sediment, reducing the need for long-term maintenance in the downstream area. This avoids the problem of sediment exacerbating the erosion of the gully head 1 and prevents potential landslides at the gully head 1.

[0027] By installing rock revetment 12 and protective netting 13, the rock revetment 12 achieves extremely strong erosion resistance when the gully head 1 encounters upstream water flow. The silt and other particles in the water flow cause continuous erosion of the slope. The rock revetment 12 effectively resists this erosion, reducing the damage and erosion of the slope soil by the water flow. The rock revetment 12 can withstand significant external pressure, including the impact force from the water flow and the weight of the soil, effectively increasing the slope's resistance to external forces and preventing slope collapse caused by water flow. The structure of the rock revetment 12 is usually irregularly arranged, which helps to disperse the water flow and reduce its speed. After contacting the rock, the kinetic energy of the water flow is gradually consumed, slowing down the flow and reducing the erosion pressure on the downstream land. Once constructed, the rock revetment 12 typically has a long service life and is not easily eroded by water flow and weather. Compared to other protective measures, the rock revetment 12 requires less frequent maintenance or replacement, resulting in lower maintenance costs, while the protective netting 13 effectively stabilizes the slope soil, preventing water erosion of the slope. By binding the soil together, the protective netting 13 reduces soil loosening and erosion, preventing large-scale soil loss caused by water erosion of the slope. The protective netting 13 forms an effective barrier on the slope, preventing water from directly impacting the soil, reducing the depth and extent of erosion, and effectively protecting the slope from excessive erosion. The protective netting 13 effectively enhances slope stability and prevents slope collapse caused by water impact. Especially in areas with steep slopes, the protective netting 13 effectively reduces the pressure of water flow on the slope, thus preventing soil slippage or collapse caused by water erosion. The protective netting 13 has a simple and durable structure, enabling it to function for a long time, reducing the need for frequent slope maintenance, and thus avoiding the problem of significantly increased management costs due to the increase in erosion gullies.

[0028] Working principle: When encountering water flow from upstream, the water first flows through the stepped structure 6, which gradually disperses the water flow into multiple small areas, preventing the water flow from concentrating in one place and thus reducing the scouring of a single location. The sedimentation tank 5 is higher than the last step of the stepped structure 6, which allows for the initial sedimentation of the water flow. When the water flow accumulates to a certain extent, it will overflow the sedimentation tank 5, allowing the water flow to pass through the sand storage trough 7, which allows for secondary sedimentation. When the water flow enters the intercepting ditch 4, under the action of the first diversion channel 8, the second diversion channel 9, the third diversion channel 10, and the fourth diversion channel 11, the water flow can flow into the first vegetation planting area 2 and the second vegetation planting area 3, respectively.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
