Description

Technical Field

[0001] The present invention relates to the technical field of riverbank buffer zones, and particularly relates to a riverbank vegetation buffer zone and an arrangement method thereof. Background Art

[0002] The riverbank vegetation buffer and purification zone belongs to the aquatic-terrestrial ecotone, which is an important habitat for aquatic and terrestrial species sources and wild animals, a source of coarse woody debris, nutrients and energy in the river stream. It directly affects the microclimate of the river stream, protects the water quality of the river stream, provides a leisure place for human outdoor activities, and provides a base for the development of agriculture, forestry, animal husbandry and fishery; the riverbank vegetation buffer zone is also an important part of nutrient management, sediment and soil erosion control and protection of the fresh water resource environment system. Whether its function can be effectively exerted is related to the health of the watershed ecosystem and is an important barrier to maintaining the stability of the terrestrial and aquatic ecosystems.

[0003] In some areas with strong wind and sand, buffer zones are generally set up by means of grouted stone and dry-laid stone, which is not conducive to the growth of animals around the riverbank. Moreover, under the long-term action of wind and sand, the buffer zone may become loose, resulting in sediment and stones falling into the river, causing water pollution. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the background art and propose a riverbank vegetation buffer zone and an arrangement method thereof.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: a riverbank vegetation buffer zone, including a support member, a spring piece and a protection net. The number of the protection nets is at least two groups. Both the upper and lower ends of the protection net are fixedly connected to the spring piece, and both sides of the spring piece are fixedly connected to the support member. The spring piece is arranged in an arc shape. Sandbags are arranged on the side of the protection net away from the river. A connecting member is arranged between the two groups of protection nets. The connecting member is connected to the support member through an adjusting mechanism. A through hole is opened in the middle of the connecting member, and tall plants are arranged inside the through hole. Soil is laid at the lowermost end of the protection net, organic fertilizer is laid above the soil, stones are laid above the organic fertilizer, and grass is planted around the tall plants.

[0006] Preferably, the adjusting mechanism includes an adjusting member, the adjusting member is rotatably sleeved outside the connecting member, grooves are opened at both ends of the adjusting member, and the grooves are connected to the support member through a fixing component.

[0007] Preferably, the fixing component includes a connecting column, the connecting column is fixedly installed above the support member, a sleeve is slidably sleeved above the connecting column, the sleeve is connected to the connecting column through an elastic structure, a limiting block is fixedly installed above the sleeve, a limiting groove is opened at the edge of the groove, and the limiting groove is slidably connected to the limiting block.

[0008] Preferably, the elastic structure includes a first spring which is movably inserted inside the sleeve. The first spring is fixedly connected to the connecting column. A slider is fixedly installed on the outer side of the connecting column. A sliding groove is formed on the inner wall of the sleeve, and the sliding groove is slidably connected to the slider.

[0009] Preferably, a first magnet is fixedly installed below the limiting block, and a second magnet is fixedly installed above the adjusting member. The first magnet and the second magnet attract each other.

[0010] Preferably, a grounding column is arranged below the supporting member. The grounding column slidably penetrates through the groove. A cavity is formed inside the grounding column. A push rod is slidably inserted inside the cavity. The upper end of the push rod is fixedly connected to the bottom of the supporting member. A stabilizing structure is arranged inside the cavity.

[0011] Preferably, the stabilizing structure includes a mounting block and a limiting hole. The limiting hole is formed on the outside of the grounding column. The mounting block slidably penetrates through the limiting hole. The mounting block is inclined. A second spring is movably sleeved on the outside of the mounting block. The second spring is fixedly connected to the inner wall of the grounding column. A protrusion is fixedly installed on the outside of the grounding column.

[0012] Preferably, there are at least two groups of protective nets in the horizontal direction. A fixing plate is arranged above two adjacent groups of supporting members. A card slot is formed inside the fixing plate. The card slot is slidably connected to the grounding column. A protective structure is arranged between the two fixing plates.

[0013] Preferably, the protective structure includes a supporting plate. The number of the supporting plates is two. The two supporting plates are respectively fixedly installed on the adjacent sides of the two fixing plates. Two adjusting plates are rotatably installed on the side of the supporting plate away from the fixing plate. A shaft member is rotatably installed at the common end of two adjacent adjusting plates away from the supporting plate. Short plants are planted among the four adjusting plates.

[0014] A layout method of a riverbank vegetation buffer zone is carried out by using the above-mentioned riverbank vegetation buffer zone, and includes the following:

[0016] S2. The protective net is fixed on the riverbank through the grounding column. The bending radian of the elastic sheet is adjusted through the adjusting member. The sandbag is arranged on one side of the protective net, and the two protective nets are designed in a trapezoid shape.

[0017] S3. Adjacent two groups of protective nets are connected by arranging the fixing plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The invention can increase the nutrients in the soil through organic fertilizers, and stones can reduce the impact of sand and wind on the soil. By successively planting tall plants and short plants, the wind resistance can be reduced, and at the same time, the protection effect on the riverbank can be improved. The grass clumps where tall plants and short plants are planted can further protect the soil, so that when it rains and is washed by rainwater, the soil on the riverbank will not flow into the river along with the rainwater.

[0020] 2. The invention sets multiple groups of protective nets in the same row, and the protective nets are designed in a fish-scale shape. When rainwater flows, when the water flow reaches between two groups of protective nets, it can flow along the surface of the protective nets to the middle of the protective nets, playing a certain role in diverting and buffering the water flow, so that the flowing water will not wash the soil on the riverbank into the river.

[0021] 3. The invention sets the protective nets in a stepped shape, which can further slow down the speed of the water flow, thereby reducing the impact of sand and wind and water flow on the riverbank. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0032] As Figures 1-8 shown, a riverbank vegetation buffer zone includes a support member 1, an elastic piece 2 and a protective net 3. The number of the protective nets 3 is at least two groups. Both the upper and lower ends of the protective net 3 are fixedly connected to the elastic piece 2, and both sides of the elastic piece 2 are fixedly connected to the support member 1. The elastic piece 2 is arranged in an arc shape. A sandbag 9 is arranged on the side of the protective net 3 away from the river. A connecting member 11 is arranged between the two groups of protective nets 3. The connecting member 11 is connected to the support member 1 through an adjusting mechanism. A through hole 13 is formed in the middle of the connecting member 11, and tall plants 6 are arranged inside the through hole 13. Soil 4 is laid at the lowermost end of the protective net 3, organic fertilizer 5 is laid above the soil 4, stones 10 are laid above the organic fertilizer 5, and grass clumps 8 are planted around the tall plants 6.

[0033] Specifically, the adjusting mechanism includes an adjusting member 12. The adjusting member 12 is rotatably sleeved outside the connecting member 11. Grooves 14 are formed at both ends of the adjusting member 12, and the grooves 14 are connected to the support member 1 through a fixing component.

[0034] The fixing component includes a connecting column 16. The connecting column 16 is fixedly installed above the support member 1. A sleeve 17 is slidably sleeved above the connecting column 16. The sleeve 17 is connected to the connecting column 16 through an elastic structure. A limiting block 21 is fixedly installed above the sleeve 17. A limiting groove 15 is formed at the edge of the groove 14, and the limiting groove 15 is slidably connected to the limiting block 21.

[0035] Specifically, the elastic structure includes a first spring 20. The first spring 20 is movably inserted inside the sleeve 17. The first spring 20 is fixedly connected to the connecting column 16. A slide block 19 is fixedly installed on the outer side of the connecting column 16. A slide groove 18 is formed on the inner wall of the sleeve 17, and the slide groove 18 is slidably connected to the slide block 19.

[0036] Furthermore, a first magnet 22 is fixedly installed below the limit block 21, and a second magnet 23 is fixedly installed above the adjusting member 12. The first magnet 22 and the second magnet 23 attract each other.

[0037] Furthermore, a grounding post 24 is arranged below the support member 1. The grounding post 24 slidably penetrates the groove 14. A cavity 25 is formed inside the grounding post 24. A push rod 27 is slidably inserted into the cavity 25. The upper end of the push rod 27 is fixedly connected to the bottom of the support member 1. A stabilizing structure is arranged inside the cavity 25.

[0038] Specifically, the stabilizing structure includes a mounting block 26 and a limiting hole 29. The limiting hole 29 is formed in the outer part of the grounding post 24. The mounting block 26 slidably penetrates the limiting hole 29. The mounting block 26 is inclined. A second spring 28 is movably sleeved on the outer part of the mounting block 26. The second spring 28 is fixedly connected to the inner wall of the grounding post 24. A protrusion 30 is fixedly installed on the outer part of the grounding post 24.

[0039] Furthermore, there are at least two groups of horizontal protection nets 3. A fixing plate 31 is arranged above adjacent two groups of support members 1. A card slot 32 is formed inside the fixing plate 31. The card slot 32 is slidably connected to the grounding post 24. A protection structure is arranged between the two groups of fixing plates 31.

[0040] The protection structure includes two support plates 33. The two support plates 33 are respectively fixedly installed on the adjacent sides of the two groups of fixing plates 31. Two adjusting plates 34 are rotatably installed on the side of the support plate 33 away from the fixing plate 31. A shaft member 35 is rotatably installed at the common end of the adjacent two groups of adjusting plates 34 away from the support plate 33. Low plants 7 are planted among the four adjusting plates 34.

[0041] A layout method for a riverbank vegetation buffer zone is carried out by using the riverbank vegetation buffer zone described above, including the following:

[0042] S1. Organic fertilizer 5 is laid on the soil 4. Gravel 10 is laid above the organic fertilizer 5. Tall plants 6 and low plants 7 are sequentially planted above the gravel 10. Grass clusters 8 are planted around the tall plants 6 and the low plants 7.

[0043] S2. The protection net 3 is fixed on the riverbank through the grounding post 24. The bending radian of the elastic sheet 2 is adjusted through the adjusting member 12. The sandbag 9 is arranged on one side of the protection net 3, and the two groups of protection nets 3 are designed in a trapezoidal shape.

[0044] S3. The adjacent two groups of protection nets 3 are connected by setting the fixing plate 31.

[0045] During use, the soil 4 is laid on the river bank, and the organic fertilizer 5 is laid above the soil 4. The upper and lower groups of protective nets 3 are connected by the adjusting member 12. At this time, the two groups of protective nets 3 are designed in a stepped shape. The upper protective net 3 sleevs the adjusting member 12 outside the grounding post 24, and the lower protective net 3 sleevs the adjusting member 12 outside the connecting post 16 and the sleeve 17. During this process, the sleeve 17 passes through the through hole 13, and the limiting block 21 slides inside the limiting groove 15. When the limiting block 21 is removed from the inside of the limiting groove 15, under the action of the connecting member 11, the adjusting member 12 is rotated. At this time, the limiting block 21 rotates to a position where it does not coincide with the limiting groove 15, so that the sleeve 17 will not separate from the adjusting member 12. Under the mutual cooperation of the first magnet 22 and the second magnet 23, the sleeve 17 will not protrude above the adjusting member 12, which is applicable to adjusting members 12 of different thicknesses and can increase the stability between the support member 1 and the adjusting member 12.

[0046] The distance between the support members 1 on both sides of the protective net 3 can be adjusted by the adjusting member 12. Under the action of the elastic piece 2, the arc of the protective net 3 is adjusted. A sandbag 9 is arranged on one side of the protective net 3, which can effectively reduce the soil erosion of the river bank, reduce the influence of wind and sand on the river bank, and prevent the objects on the river bank from slipping into the river easily.

[0047] The grounding post 24 is inserted into the soil 4. When the protrusion 30 contacts the surface of the organic fertilizer 5, the grounding post 24 stops moving. The support member 1 continues to drive the push rod 27 to move into the cavity 25. When the push rod 27 contacts the mounting block 26, the push rod 27 pushes the mounting block 26 to move outside the grounding post 24 inside the limiting hole 29. At this time, the second spring 28 is compressed. The mounting block 26 is inserted into the soil 4, increasing the contact area between the device and the soil 4, thereby increasing the stability of the device.

[0048] Furthermore, when there are at least two groups of protective nets 3 in the same row, the two groups of card slots 32 opened on the fixing plate 31 are respectively sleeved outside the sleeves 17 installed on the adjacent two support members 1, so that the two groups of protective nets 3 can be fixed together. Under the mutual cooperation of the support plate 33, the adjusting plate 34 and the shaft member 35, when adjusting the arc of one group of protective nets 3, all the protective nets 3 can be adjusted simultaneously, which is beneficial to improving the efficiency of buffer zone layout. And when the water flow impacts between the two groups of protective nets 3, it can flow along the surface of the protective net 3 towards the center of the protective net 3, reducing the impact force of the water flow on the soil and being beneficial to reducing the soil erosion of the river bank.

[0049] The tall plants 6 are planted inside the through holes 13 opened on the connecting member 11, while the short plants 7 are planted between the four groups of adjusting plates 34, which can effectively reduce the impact of the wind on the tall plants 6 and the short plants 7, so that the tall plants 6 and the short plants 7 will not be blown down in strong winds. The grass clumps 8 are planted around the tall plants 6 and the short plants 7 to further improve the stability of the buffer zone. The gravel 10 is laid in the gaps of the grass clumps 8, and the gravel 10 is located above the organic fertilizer 5, thereby being able to further reduce the impact of sand and dust on the soil 4.

[0050] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
