Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of collapse gully control, and specifically, to a plant measure system for collapse gully erosion control. Background Art
[0002] Collapse gully is a kind of mountain disaster in the south of China. After the thick weathered crust of the mountain body undergoes gravity erosion such as collapse, an erosion landform is formed by water scouring. Generally, it includes 5 parts: catchment area, collapse wall, colluvial deposit, gully and alluvial fan. Collapse gully is regarded as the ecological ulcer in the south of China, with large erosion intensity. It not only destroys land resources, but also a large amount of sediment flowing downward often buries farmland roads, and can cause siltation of river channels and reservoirs, affecting the flood discharge capacity of river channels.
[0003] The current collapse gully control mode is mainly the mode of "intercepting at the top, blocking at the bottom, cutting in the middle, and greening inside and outside". "Intercepting at the top" means excavating a catchment ditch at the top of the collapse gully, "blocking at the bottom" means building a sediment retention dam in the gully, "cutting in the middle" means cutting and grading the collapse wall, and "greening inside and outside" means planting trees and grass in the collapse gully. This mode involves a large number of engineering measures. Since the location of the collapse gully is often inconvenient in transportation, it is difficult for large machinery to enter, and the construction cost is high. Moreover, due to the large amount of sediment in the collapse gully, the sediment retention dam is easy to be silted up and washed away, and the subsequent maintenance cost is also high. Content of the Utility Model
[0004] In order to solve the problems of high construction cost and subsequent maintenance cost in the collapse gully control in the above-mentioned existing technical solutions, the utility model provides a plant measure system for collapse gully erosion control. The plant measure system in this solution is a non-engineering measure. During implementation, large machinery is not required, the construction is convenient, and the sediment interception effect can be sustainable, which can reduce the control cost and subsequent maintenance cost.
[0005] The technical solution adopted by the utility model is: a plant measure system for collapse gully erosion control, including a fence retaining body and a plant sediment retaining body. Both the fence retaining body and the plant sediment retaining body are located in the collapse gully. There are several fence retaining bodies, and several fence retaining bodies are linearly arranged along the water flow direction in the collapse gully. The plant sediment retaining body includes several plants, and several plants are linearly arranged perpendicular to the water flow direction in the collapse gully to form plant rows. There are several plant rows, and several plant rows are linearly arranged along the water flow direction in the collapse gully.
[0006] Plants are planted throughout the collapse gully. The dry branches of the plants form the plant sediment retaining body. Several fence retaining bodies are constructed to slow down the water scouring, ensure the survival of the plants, and can intercept sediments of different particle sizes. After the fine-grained sediment is deposited, the soil conditions of the gully bed can be improved.
[0007] This solution only uses plant measures to control collapse gullies. Compared with building sediment retaining dams, it does not require the use of large machinery for auxiliary construction, has less construction volume, and lower construction costs. The plants planted in this solution can still grow and reproduce normally under the condition of sediment burial. They are not only not easily washed away, but also have no defect of subsequent heightening required for general earth-rock dams, and the subsequent maintenance costs are also low.
[0008] Preferably, the plants include large plants with a mature plant height greater than 2m and medium-sized plants with a mature plant height of 1m - 2m. The large plants are linearly arranged along the fence retaining body in the collapse gully to form large plant rows, and the medium-sized plants are linearly arranged along the fence retaining body in the collapse gully to form medium-sized plant rows. The plant sediment retaining dam located in the collapse gully is composed of medium-sized plant rows and large plant rows. Since herbaceous plants grow rapidly, the plant sediment retaining dam generally selects herbaceous plants for construction, that is, the large plants can be large herbaceous plants, and the large herbaceous plants form large herbaceous plant rows; the medium-sized plants can be medium-sized herbaceous plants, and the medium-sized herbaceous plants form medium-sized herbaceous plant rows. In addition, since bamboo plants grow rapidly, the large herbaceous plants can also be replaced by small bamboo plants, such as Schizostachyum brachycladum, Rhapis excelsa, and Bambusa multiplex.
[0009] Preferably, the row spacing between two adjacent large plant rows is 0.7m - 0.9m, and the plant spacing between two adjacent large plants in the same large plant row is 0.3m - 0.4m. The medium-sized plants planted in the downstream of the gully are denser than those planted in the upstream of the gully. In the downstream area of the collapse gully, there are two medium-sized plant rows between two adjacent large plant rows, the row spacing between the two medium-sized plant rows is 0.2 - 0.3m, and the plant spacing between two adjacent medium-sized plants in the same medium-sized plant row is 0.15 - 0.25m. In the upstream area of the collapse gully, there is one medium-sized plant row between two adjacent large plant rows, and the plant spacing between two adjacent medium-sized plants in the same medium-sized plant row is 0.3m - 0.4m. Medium-sized plants can be densely planted and often have strong spreading ability, so they can ensure the sediment retaining efficiency, but their ability to resist sediment burial is not strong. Large plants have strong ability to resist sediment burial, and after shading the ground surface, they can provide a better habitat for medium-sized herbaceous plants, which is conducive to the recovery of medium-sized herbaceous vegetation under the stress of sediment burial. The plant sediment retaining dam is constructed by mixing medium-sized plants and large plants, and the medium-sized plants are planted between the large plants, which is beneficial to the survival of the plants and can also ensure a high sediment retaining efficiency.
[0010] Preferably, the large plants include large herbaceous plants such as Pennisetum purpureum, Neyraudia reynaudiana, Miscanthus floridulus, Vetiveria zizanioides, Thysanolaena latifolia, Pennisetum giganteum, and Pennisetum sinese, and small bamboo plants such as Schizostachyum brachycladum, Rhapis excelsa, and Bambusa multiplex. The medium-sized plants include medium-sized herbaceous plants such as Melinis minutiflora, Pennisetum alopecuroides, Artemisia argyi, Stylosanthes guianensis, and Ruellia brittoniana.
[0011] Preferably, the spacing between two adjacent fence barriers is 5m - 8m. The fence barrier located upstream of the gully has a notch, while the fence barrier located downstream of the gully has no notch. The notches on two adjacent fence barriers in the upstream area are respectively located at the two ends of the two fence barriers. When the spacing between two adjacent fence barriers is between 5m - 8m, it has a good sediment interception effect. It can also be densified according to the actual situation. The notch on the upstream fence barrier enables sediment to flow down from the notch, preventing excessive sediment interception by the upstream fence barrier and affecting plant growth. The notches on two adjacent fence barriers in the upstream area are respectively located at the two ends of the two fence barriers, which can increase the curvature of the water flow route and better slow down the effect of water flow scouring.
[0012] Preferably, the fence barrier includes ground piles and a fence. There are several ground piles, and several ground piles are linearly arranged in the direction perpendicular to the water flow of the gully. The fence bypasses the ground piles in sequence. The length of the ground pile is 1.2m - 1.4m, the distance that the bottom of the ground pile extends into the bottom of the gully is 0.3m - 0.5m, and the spacing between two adjacent ground piles is 0.15m - 0.25m. The ground pile can be a bamboo pile or other wooden piles, and the fence can be branches, bamboo strips, plastic meshes, and nylon meshes. The distance that the bottom of the ground pile extends into the bottom of the gully is 0.3m - 0.5m, which can firmly nail the ground pile in the gully. The spacing between two adjacent ground piles is 0.15m - 0.25m, which can make the overall fence barrier more stable and prevent it from being washed away by water and sediment.
[0013] Preferably, when planting vegetation, container seedlings with a seedling height greater than 0.3m should be selected, and the survival rate after planting is high.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: This solution only uses plant measures to control gully erosion. Compared with building a sand - retaining dam, it does not require the use of large - scale machinery for auxiliary construction, has less engineering construction, and lower construction costs. The vegetation planted in this solution can still grow and reproduce normally under the condition of being buried by sediment. It is not only not easily washed away, but also has no defect of subsequent heightening required for conventional earth - rock dams, and the subsequent maintenance cost is lower.

[0020] Embodiment 1
[0021] As Figure 1 - Figure 2 shown in FIG. 1 is Embodiment 1 of a plant measure system for controlling gully erosion, which includes a fence retaining body 2 and a plant sand retaining body. Both the fence retaining body 2 and the plant sand retaining body are located in the gully channel 1 of the gully. There are several fence retaining bodies 2, and several fence retaining bodies 2 are linearly arranged along the water flow direction A in the gully channel 1 in the gully channel 1.

The medium-sized herbaceous plants include medium-sized herbaceous plants such as Melinis minutiflora, Pennisetum alopecuroides, Artemisia argyi, Stylosanthes guianensis, and Ruellia simplex. The small bamboo plants that can replace the large herbaceous plants include Sasa palmata, Rhapis excelsa, and Bambusa multiplex.
[0025] Specifically, the row spacing between two adjacent large plant rows is 0.7 m - 0.9 m, and the plant spacing between two adjacent large plants 3 in the same large plant row is 0.3 m - 0.4 m. The medium-sized plants 4 planted in the downstream of the gully 1 are denser than those planted in the upstream of the gully 1. In the downstream area of the landslide gully 1, there are two medium-sized plant rows between two adjacent large plant rows, and the row spacing between the two medium-sized plant rows is 0.2 - 0.3 m, and the plant spacing between two adjacent medium-sized plants 4 in the same medium-sized plant row is 0.15 - 0.25 m. In the upstream area of the landslide gully, there is one medium-sized plant row between two adjacent large plant rows, and the plant spacing between two adjacent medium-sized plants 4 in the same medium-sized plant row is 0.3 m - 0.4 m. (The number of large herbaceous plants and medium-sized herbaceous plants in the attached drawings does not represent the actual quantity).
[0026] Specifically, the spacing between two adjacent fence retaining walls 2 is 5 m - 8 m. The fence retaining wall 2 located in the upstream of the landslide gully 1 is provided with a notch, and the fence retaining wall 2 located in the downstream of the landslide gully 1 is not provided with a notch. The notches on two adjacent fence retaining walls 2 in the upstream area are respectively located at both ends of the two fence retaining walls 2.
[0027] Specifically, the fence retaining wall 2 includes ground piles 201 and fences 202. There are several ground piles 201, and several ground piles 201 are linearly arranged in the direction perpendicular to the axis of the landslide gully 1, and the fence 202 successively bypasses the ground piles 201.

The ground pile 201 is a bamboo pile, and the fence 202 is a branch.
[0028] Advantages of the present utility model: This solution only uses plant measures to control landslides. Compared with building sediment retaining dams, it does not require the assistance of large machinery for construction, has less engineering construction, and low construction costs. The herbaceous plants planted in this solution can still grow and reproduce normally under the condition of being buried by sediment. They are not only not easily washed away, but also do not have the defect of subsequent heightening required for conventional earth and stone dams, and the subsequent maintenance costs are low.
[0029] The herbaceous plants are container seedlings with a seedling height greater than 0.3m, and the survival rate of the plants is high after being planted.
[0030] The landslide gully 1 constructs a plant sediment retaining body by mixing and planting large herbaceous plants 3 and medium herbaceous plants 4. The medium herbaceous plants 4 are planted between the large herbaceous plants 3. The large herbaceous plants 3 can provide a better living environment for the medium herbaceous plants 4, which is beneficial to the recovery of the medium herbaceous plants 4 under the condition of being buried by sediment. It not only improves the survival rate of the plants, but also ensures the sediment interception rate of the plant sediment retaining body.
[0031] When the distance between two adjacent fence retaining bodies 2 is between 5m and 8m, it has a good sediment retaining effect. The gaps on two adjacent fence retaining bodies in the upstream area are located at both ends of the two fence retaining bodies respectively, which can increase the curvature of the water flow route and better slow down the effect of water flow scouring.
[0032] The bottom of the ground pile 201 extends into the bottom of the landslide gully 1 by a distance of 0.3m - 0.5m, which can make the ground pile 201 firmly nailed in the landslide gully 1. The distance between two adjacent ground piles 201 is 0.15m - 0.25m, making the overall fence retaining body 2 more stable and avoiding being washed away by water flow and sediment. The bamboo piles and branches are convenient to arrange, have low cost, and good sediment retaining effect.
[0033] Embodiment 2
[0034] An embodiment 2 of a plant measure system for controlling landslide erosion verifies the field implementation results of the landslide control system on the basis of Embodiment 1.
[0035] Specifically, the implementation location is Dongyuan Village, Huacheng Town, Wuhua County, Guangdong Province, and the construction started on March 7, 2022. The landslide at this place is still in the active period. After the landslide wall collapsed, a large amount of loose sand sources were generated. It was severely eroded during rainfall, and the huge amount of sediment generated was directly discharged into the downstream river channel. Before treatment, the gully bed was mainly composed of gravel, lacking soil and almost no grass growing.
[0036] The specific implementation measures are as follows: Along the cross-sectional direction of the landslide gully 1, bamboo piles are driven in at intervals of about 20cm. The cross-sectional direction of the bamboo piles is parallel to the water flow direction. The height of the bamboo piles is about 1.3 meters, and they are driven into the ground about 40cm. Branches are used for transverse connection between the bamboo slices to form a fence shape from bottom to top, that is, the fence retaining body 2. Generally, a fence retaining body 2 is built every 5 - 8 meters.
[0037] Tall herbaceous plants, including elephant grass and nardus grass, are planted in the gully of the landslide gully 1, with a row spacing and plant spacing of 0.8 m and 1 / 3 m respectively. In the downstream area of the landslide gully 1, two rows of medium-sized herbaceous plants, including ruellia and melinis minutiflora, are planted between adjacent rows of large herbaceous plants, with a plant spacing of 0.2 m and a row spacing of 0.2 m. In the upstream area of the landslide gully 1, one row of medium-sized herbaceous plants is planted in the center between adjacent rows of large herbaceous plants, with a plant spacing of 1 / 3 m.
[0038] The above-mentioned elephant grass and nardus grass are planted by transplantation method, while ruellia and melinis minutiflora are planted with container seedlings.
[0039] The experimental results show that: after construction, the sediment interception effect of the fence retaining body 2 is remarkable, the gully bed is significantly lifted, and at the same time, a large amount of fine particles are deposited, creating good conditions for plant growth. At present, the sediment deposition depth in the upstream area has exceeded 1.5 m, 60 - 70 cm in the middle reaches, and 30 - 40 cm in the downstream area. Although most of the fence retaining body 2 has been buried, the vegetation in the landslide gully 1 grows well and can still ensure a good sediment interception effect.
[0040] Example 3
[0041] Example 3 of a plant measure system for controlling landslide erosion. On the basis of Example 1 or Example 2, the field implementation results of the landslide control system are verified by changing the location.
[0042] Specifically, the implementation location is Dongyuan Village, Huacheng Town, Wuhua County, Guangdong Province, and the construction started on March 10, 2022. The downstream of this landslide is a local gas factory. There was a sediment interception dam built at the gully mouth before, but this dam was washed away in 2021. The sediment of the landslide directly flowed down into the gas factory, burying the factory land and seriously affecting normal production. The outlet of this landslide is a steep cliff about 5 meters high, and all construction materials need to be first transported to the top of this cliff, with poor construction conditions. According to the traditional engineering treatment method, the construction cost is extremely high.
[0043] The specific implementation measures are as follows: Along the cross-section direction of the landslide gully 1, bamboo piles are driven in at intervals of about 20 cm. The cross-section direction of the bamboo piles is parallel to the water flow direction, and the height of the bamboo piles is about 1.3 m, and they are driven into the ground about 40 cm. Branches are used for horizontal connection between the bamboo slices, forming a fence-like shape from bottom to top, that is, the fence retaining body 2. Generally, a fence retaining body 2 is built every 5 - 8 m, and a total of 13 fence retaining bodies 2 are built.
[0044] Plant large herbaceous plants, including Pennisetum purpureum and Neyraudia reynaudiana, in the collapse gully 1, with a row spacing and plant spacing of 0.8 m and 1 / 3 m respectively. In the downstream area of the collapse gully 1, plant two rows of medium-sized herbaceous plants, including Ruellia brittoniana and Melinis minutiflora, between adjacent rows of large herbaceous plants, with a plant spacing of 0.2 m and a row spacing of 0.2 m. In the upstream area of the collapse gully 1, plant one row of medium-sized herbaceous plants in the center between adjacent rows of large herbaceous plants, with a plant spacing of 1 / 3 m.
[0045] The above-mentioned Pennisetum purpureum and Neyraudia reynaudiana are planted by transplantation method, and Ruellia brittoniana and Melinis minutiflora are planted with container seedlings.
[0046] The experimental results show that: after the project implementation, the fence retaining body 2 immediately played a role, and the harm of sediment discharge was eliminated. After 3 months of construction, the vegetation coverage in the collapse gully 1 was close to 100%, and the height of Pennisetum purpureum and Neyraudia reynaudiana exceeded 2 m. At present, the project has withstood the tests of multiple heavy rainstorms in two flood seasons and is still operating well. The siltation depth in the upstream is about 1 m, and the siltation depth at the downstream outlet is 60 - 70 cm.
[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
