Description

Technical Field

[0001] This invention relates to the field of ecological slope protection technology, and in particular to a seasonal river landscape ecological slope protection method. Background Technology

[0002] Seasonal rivers, also known as intermittent or seasonal rivers, are rivers that dry up and have exposed riverbeds during the dry season, but flow and even flood during the wet season. These rivers typically flow through hot, arid regions and have relatively small annual average flows, but can experience large flood peaks due to torrential rains and snowmelt. Seasonal river environments are not only a common landscape feature but also important ecological corridors and recreational resources, possessing significant value in environmental protection and tourism development.

[0003] Seasonal riverbank protection serves as a major transitional zone for the exchange of matter, energy, and information between aquatic and terrestrial ecosystems. It exhibits significant edge effects, providing space for the survival and reproduction of various aquatic organisms. Furthermore, it plays a vital role in enhancing biodiversity, controlling soil erosion, stabilizing riverbanks, regulating climate, and beautifying the environment.

[0004] Patent application publication number CN103469765A discloses an ecological slope protection unit and the ecological slope protection structure composed of it. This ecological slope protection unit mainly consists of a first frame and a second frame, which are stacked and connected, and are hollow inside. Geotextile is provided at the overlapping area to close the opening, and geotextile is provided in the lower second frame to close the lower opening. Specifically, the portion of the upper first frame that does not overlap with the lower second frame forms a first splicing part, and the portion of the lower second frame that does not overlap with the upper first frame forms a second splicing part. The ecological slope protection structure is formed by connecting the first splicing parts of at least two slope protection units to the second splicing parts. The ecological slope protection unit and slope protection structure of this invention have the characteristics of simple structure, easy construction, convenient maintenance, and environmental friendliness.

[0005] However, in practical application, when installing slope protection units on the embankment, the lack of connection between the units and between the units and the embankment, coupled with the absence of a good connecting structure between the ecological slope protection structures, leads to loosening of the units due to prolonged rain erosion or the rushing water during the high-water season. This reduces the slope protection effect. Furthermore, if the seeds placed in the second frame are newly sprouted and their root systems are underdeveloped, soil erosion within the second frame is highly likely. Because the root system on the surface of the vegetation is also underdeveloped, the vegetation is easily washed away by the water flow after soil erosion, rendering the vegetation protection ineffective for slope protection. In addition, after the installation of this ecological slope protection unit, the riverbank slope not only has a relatively monotonous landscape effect, but people can only view it from above and cannot participate in it, thus reducing the interactivity of the slope protection. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this invention provides a seasonal river landscape ecological slope protection system. Through stable and firmly connected ecological units, it is not easy to loosen. The plants used for landscape greening and ecological restoration are in the form of erosion-resistant biological blankets, which are not easily washed away by water flow, ensuring the effectiveness of slope protection, improving the interactivity of the slope protection system, and enhancing the landscape effect.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a seasonal river landscape ecological slope protection, comprising a slope protection main body constructed on a riverbank, the slope protection main body being divided into three sections: upper, middle, and lower. The upper and lower sections of the slope protection main body are inclined, while the middle section is horizontal. The slope protection main body is constructed by setting up formwork and pouring concrete according to drawings. During concrete pouring, the slope protection main body is equipped with embedded rods, which are arranged in groups of five, with one thicker rod and four thinner rods forming a square. The pre-embedded rod is located at the center of four thinner pre-embedded rods. Each group of pre-embedded rods is equipped with a connecting block. A waste sleeper is installed between two adjacent connecting blocks. Every four connecting blocks and the corresponding waste sleeper form an ecological unit. A sand and gravel layer is laid flat in the ecological unit. A soil base layer is laid flat on the sand and gravel layer. An anti-erosion biological blanket is laid flat on the soil base layer. Fixing components for pressing the waste sleeper and the anti-erosion biological blanket are installed at the corners of the connecting blocks. A pressure plate for pressing the anti-erosion biological blanket is installed on the waste sleeper.

[0008] The slope protection structure is equipped with landscape staircases at intervals, and the ecological units in the middle section of the slope protection structure are equipped with landscape platforms at intervals.

[0009] As a preferred technical solution of the present invention, the connecting block is provided with a mounting hole of one coarse and four fine ones that are adapted to the pre-embedded rod. A nylon threaded sleeve is installed in the finer mounting hole. After the connecting block is connected to the mounting hole and the nylon threaded sleeve is installed, the anchoring agent is poured.

[0010] The connecting block is a precast concrete component, with its four corners recessed, and the fixing component is installed at the recessed positions of the four corners of the connecting block.

[0011] As a preferred embodiment of the present invention, the abandoned railway sleeper includes a sleeper body and a spiral spike fixed on the sleeper body, and a limiting groove is cut out above both ends of the abandoned railway sleeper.

[0012] As a preferred embodiment of the present invention, the fixing component includes a fixing plate, which is disposed in the sinking position of the connecting block and the limiting groove. The fixing plate is provided with a boss, and a fixing nail is fixedly disposed at the bottom of the fixing plate. The boss and the fixing nail are pressed against the surface of the impact-resistant bio-mat. A spiral anchor is inserted in the boss, and the spiral anchor penetrates the impact-resistant bio-mat and is screwed into the nylon threaded sleeve.

[0013] As a preferred embodiment of the present invention, the impact-resistant bio-blanket comprises a solid mesh, a composite fiber fabric layer, a filter layer, a grass seed layer and a thin fiber layer that are interconnected from top to bottom.

[0014] The solid mesh has a density of 10-20 g / m², a mesh size of 10 mm * 10 mm, and a tensile strength of not less than 0.8 kN / m. The composite fiber fabric layer is made of high-strength polyester and is mechanically woven, with a longitudinal tensile strength of not less than 11.6 kN / m. The filter layer is made of non-woven fabric. The grass seed layer is a mixture of grass seeds, fertilizer, and water-retaining agent. The thin fiber layer is made of polylactic acid composite fiber.

[0015] As a preferred embodiment of the present invention, the spiral spike can penetrate the pressure plate and be threaded with a locking nut. The surface of the pressure plate is provided with uniformly distributed through holes. The pressure plate has a "well" shaped structure, and multiple ports of the pressure plate are provided with notches. The notches between adjacent pressure plates are mutually compatible.

[0016] As a preferred embodiment of the present invention, the landscape platform includes several assembly frames, which are mounted on a pressure plate. The spiral road spikes pass through the pressure plate and the assembly frames in sequence and are locked by locking nuts. An assembly platform is mounted on the top of the assembly frame, and a corridor extending to the river slope is mounted on one side of the assembly platform. A guardrail is installed between the corridor and the top of the assembly platform.

[0017] As a preferred embodiment of the present invention, a support strip is installed between the bottom of the corridor and the corresponding assembly frame. The support strip has three fixing points, which are respectively fixed to the inner side of the assembly frame, the bottom of the corridor, and the slope protection body.

[0018] As a preferred embodiment of the present invention, a pad is provided between the bottom of the assembly frame and the sleeper body, the thickness of the pad is the same as the thickness of the pressure plate, and the spiral rail spike can penetrate the pad.

[0019] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0020] The ecological units are connected to the main slope protection body through pre-embedded rods. The ecological units are connected to each other through fixing components and pressure plates. Even if rainwater erosion occurs for a long time or the water flow forms a rushing water during the rainy season, the ecological units will not loosen between ecological units or between ecological units and the main slope protection body, thus providing a slope protection effect.

[0021] The plants used for landscaping and ecological restoration exist in the form of erosion-resistant bio-mats, which have the characteristics of overall structural stability and outstanding erosion resistance. The roots of the grass seeds can penetrate through the thin fiber layer and take root in the soil base and gravel layer, making them less likely to be washed away by water flow, thus reducing soil erosion. Even when the grass seeds are just growing and their root system is not well developed, the special structure of the erosion-resistant bio-mat will not easily be washed away by water flow, ensuring the effectiveness of vegetation in protecting the slope.

[0022] Seasonal rivers have dry and wet seasons. During the dry season, people can walk along the main body of the revetment through the landscape staircase to enjoy the view. During the wet season, when the river water rises, people can enter the landscape platform to enjoy the view, which improves the interactivity of the main body of the revetment and further enhances its landscape effect.

[0023] Ecological units are formed by connecting discarded railway sleepers and precast concrete components, effectively utilizing discarded railway sleepers and directly reducing construction costs. Attached Figure Description

[0037] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention. Example

[0038] like Figure 1 - Figure 12As shown, this embodiment proposes a seasonal river landscape ecological slope protection method, including a slope protection main body 100 constructed on the river slope. The slope protection main body 100 is divided into three sections: upper, middle, and lower. The upper and lower sections of the slope protection main body 100 are inclined, while the middle section is horizontal. The slope protection main body 100 is constructed by setting up formwork and pouring concrete according to drawings. During the concrete pouring, the slope protection main body 100 is equipped with embedded rods 200. The embedded rods 200 are arranged in groups of five, with one thick and four thin rods. The four thinner embedded rods 200 form a square, and the thicker embedded rod 200 is located in the middle of the four thinner embedded rods 200. At the core position, each set of pre-embedded rods 200 is equipped with a connecting block 301. A discarded sleeper 302 is installed between two adjacent connecting blocks 301. Every four connecting blocks 301 and the corresponding discarded sleepers 302 form an ecological unit 300. A sand and gravel layer 303 is laid flat inside the ecological unit 300. A soil base layer 304 is laid flat on the sand and gravel layer 303. An anti-erosion biological blanket 305 is laid flat on the soil base layer 304. Fixing components 306 for pressing the discarded sleepers and anti-erosion biological blanket 305 are installed at the corners of the connecting blocks 301. A pressure plate 307 for pressing the anti-erosion biological blanket 305 is installed on the discarded sleepers.

[0039] Among them, the main slope protection structure 100 is equipped with landscape staircases 400 at intervals, and the ecological units 300 in the middle section of the main slope protection structure 100 are equipped with landscape platforms 500 at intervals.

[0040] As a preferred embodiment of the present invention, the connecting block 301 has one coarse and four fine mounting holes 3011 adapted to the embedded rod 200. A nylon threaded sleeve 3012 is installed in the finer mounting hole 3011. After the connecting block 301 is aligned with the mounting hole 3011 and the nylon threaded sleeve 3012 is installed, an anchoring agent is poured. The connecting block 301 is a precast concrete component. The four corners of the connecting block 301 are recessed. The fixing components 306 are installed at the recessed positions of the four corners of the connecting block 301. The abandoned sleeper 302 includes a sleeper body 3021 and a spiral spike fixed on the sleeper body 3021. 3022, Restriction grooves 3023 are cut above both ends of the abandoned sleeper 302. The fixing component 306 includes a fixing plate 3061. The fixing plate 3061 is set in the sinking position of the connecting block 301 and in the restriction groove 3023. A boss 3062 is provided on the fixing plate 3061. A fixing nail 3063 is fixedly provided at the bottom of the fixing plate 3061. The boss 3062 and the fixing nail 3063 are pressed against the surface of the impact-resistant biological blanket 305. A spiral anchor nail 3064 is inserted in the boss 3062. The spiral anchor nail 3064 penetrates the impact-resistant biological blanket 305 and is screwed into the nylon threaded sleeve 3012.

[0041] As a preferred technical solution of the present invention, the impact-resistant bio-blanket 305 includes a solid mesh 3051, a composite fiber fabric layer 3052, a filter layer 3053, a grass seed layer 3054, and a thin fiber layer 3055 connected from top to bottom. The density of the solid mesh 3051 is 10-20 g / m², and the mesh size is 10 mm * 10 mm. The tensile strength is not less than 0.8 kN / m. The composite fiber fabric layer 3052 is made of high-strength polyester and is mechanically woven. The longitudinal tensile strength is not less than 11.6 kN / m. The filter layer 3053 is made of non-woven fabric. The grass seed layer 3054 is a mixture of grass seeds, fertilizer, and water-retaining agent. The thin fiber layer 3055 is made of polylactic acid composite fiber.

[0042] Specifically, the longitudinal tensile strength of the composite fiber fabric layer 3052 is not less than 11.6 kN / m, which can resist the erosion of water flow at a velocity of 4 m / s, achieving overall structural stability and outstanding impact resistance. The fixed mesh 3051 further stabilizes the overall structure on this basis. The grass seed layer 3054 is equipped with fertilizer and water-retaining agent, which can accelerate the germination and growth of grass seeds and extend the green vegetation cover time, achieving the effect of extending the green vegetation cover time. It also has high air permeability and water retention, maintaining topsoil moisture to facilitate seed germination and reduce seed waste. When the grass seeds grow, their roots can penetrate the thin fiber layer 3055 and take root in the soil base layer 304 and the sand and gravel layer 303.

[0043] The thin fiber layer 3055, made of polylactic acid composite fiber, has physical properties close to those of PET fiber (polyester) and PA fiber (nylon). It has strong impact resistance and tensile strength, which helps to fix grass seeds and prevent them from scattering. It is also biodegradable and can be decomposed into carbon dioxide and water by microorganisms in soil or water. It is pollution-free and provides nutrients for grass seed roots. The grass seed roots are firmly rooted in the soil base layer 304 and the sand and gravel layer 303 and are not easily washed away by water flow, thus reducing soil erosion.

[0044] As a preferred technical solution of the present invention, the spiral rail spike 3022 can penetrate the pressure plate 307 and is threadedly connected to the locking nut 308. The surface of the pressure plate 307 is provided with uniformly distributed through holes 3071. The pressure plate 307 has a "well" shaped structure, and multiple ports of the pressure plate 307 are provided with notches 3072. The notches 3072 between adjacent pressure plates 307 are mutually compatible.

[0045] Specifically, the pressure plate 307 can compact the erosion control bio-mat 305, so that the erosion control bio-mat 305 will not be washed away even when it is hit by water flow. Furthermore, the through holes 3071 on the pressure plate 307 allow vegetation to pass through without affecting the growth of the vegetation.

[0046] As a preferred embodiment of the present invention, the landscape platform 500 includes a plurality of assembly frames 501, which are mounted on a pressure plate 307. Spiral road spikes 3022 pass sequentially through the pressure plate 307 and the assembly frames 501 and are locked by locking nuts 308. A prefabricated platform 502 is mounted on the top of the assembly frames 501. A walkway 503 extending to the riverbank slope is mounted on one side of the prefabricated platform 502. A [fabricated structure / structure] is installed between the walkway 503 and the top of the prefabricated platform 502. A support bar 505 is installed between the bottom of the guardrail 504 and the corridor 503 and the corresponding assembly frame 501. The support bar 505 has three fixing points, and the three fixing points of the support bar 505 are respectively fixed to the inner side of the assembly frame 501, the bottom of the corridor 503 and the slope protection body 100. A pad 506 is provided between the bottom of the assembly frame 501 and the sleeper body 3021. The thickness of the pad 506 is the same as the thickness of the pressure plate 307. The spiral rail spike 3022 can penetrate the pad 506.

[0047] Specifically, the locking nuts 308 on the ecological unit 300 located on the horizontal section of the slope protection body 100 and used to install the landscape platform 500 are not installed. The assembly frame 501 is connected to the corresponding spiral road studs 3022 and then fixed by the locking nuts 308. After the installation of the assembly frame 501 is completed, the prefabricated platform 502, corridor 503, guardrail 504 and support bar 505 are installed in sequence. The support bar 505 is used to support the corridor 503. During the installation of the assembly frame 501, since the pressure plates 307 on the ecological unit 300 located on the horizontal section of the slope protection body 100 only have horizontal connections, some of the notches 3072 at the ends cannot be connected with other pressure plates 307. Therefore, pads 506 are added. The pads 506 prevent the assembly frame 501 from being partially suspended and improve the stability of the installation.

[0048] Working principle of the invention:

[0049] 1) Carry out cofferdam construction, remove silt and impurities from the base layer, tie steel bars, set up formwork and pour concrete to build the main slope protection structure 100. Before pouring the main slope protection structure 100, it is necessary to add embedded rods 200, and the main slope protection structure 100 is equipped with landscape stairs 400 at intervals.

[0050] 2) After the slope protection body 100 is formed, the mounting hole 3011 of the connecting block 301 is connected with the embedded rod 200, and the anchoring agent is poured into the mounting hole 3011. During this process, the nylon threaded sleeve 3012 needs to be inserted into the corresponding mounting hole 3011 so that the slope protection body 100, the embedded rod 200, the connecting block 301 and the nylon threaded sleeve 3012 are integrated into one.

[0051] 3) After cutting out the limiting groove 3023 from the abandoned railway sleepers 302, they are hoisted between two adjacent connecting blocks 301. The abandoned sleepers 302 are initially positioned by the connecting blocks 301. Every four connecting blocks 301 and the corresponding four abandoned sleepers 302 form an ecological unit 300.

[0052] 4) Lay a layer of sand and gravel 303 and a soil base layer 304 in sequence in the gap between the four abandoned sleepers 302 and compact them. Then lay the prefabricated erosion-resistant biological blanket 305 on the soil base layer 304.

[0053] 5) Place the fixing plate 3061 in the corresponding sinking position of the connecting block 301 and the limiting groove 3023, pass the spiral anchor 3064 through the boss 3062 and insert it into the mounting hole 3011, and then screw the spiral anchor 3064 into the nylon threaded sleeve 3012 in the mounting hole 3011. After the spiral anchor 3064 is tightened, the fixing plate 3061 can be pressed into the limiting groove 3023. The boss 3062 and fixing nail 3063 on the fixing plate 3061 can be pressed onto the impact-resistant biological blanket 305, and the spiral anchor 3064 passes through the impact-resistant biological blanket 305. After the fixing assembly 306 is locked, it simultaneously fixes the waste sleeper 302 and the impact-resistant biological blanket 305.

[0054] 6) Install the pressure plate 307 on the sleeper body 3021, and lock the pressure plate 307 by cooperating with the spiral spike 3022 through the locking nut 308. The pressure plate 307 can press the impact-resistant biological blanket 305 again.

[0055] 7) After the ecological unit 300 is installed, a landscape platform 500 is built at intervals between ecological units 300 in the middle section of the main slope protection 100.

[0056] In summary, the main structure involved in slope protection is the ecological unit 300. The ecological unit 300 is connected to the slope protection body 100 through the pre-embedded rod 200. The ecological units 300 are connected to each other through the fixing component 306 and the pressure plate 307. Long-term erosion by rainwater or the rushing water during the rainy season will not cause loosening between the ecological units 300 or between the ecological units 300 and the slope protection body 100, thus providing the slope protection effect.

[0057] The plants used for landscaping and ecological restoration are in the form of erosion-resistant bio-mat 305. The erosion-resistant bio-mat 305 is composed of a fixed net 3051, a composite fiber fabric layer 3052, a filter layer 3053, a grass seed layer 3054, and a thin fiber layer 3055. Based on the characteristics of its composition structure, the erosion-resistant bio-mat 305 has the properties of overall structural stability and outstanding erosion resistance. The roots of the grass seeds can penetrate the thin fiber layer 3055 and take root in the soil base layer 304 and the sand and gravel layer 303, making them less likely to be washed away by water flow, thus reducing soil erosion. Even when the grass seeds are just growing and their root system is not well developed, the special structure of the erosion-resistant bio-mat 305 will not easily wash them away by water flow, ensuring the effectiveness of vegetation in protecting the slope.

[0058] Seasonal rivers have dry and wet seasons. During the dry season, people can walk along the main body of the slope protection 100 via the landscape staircase 400 to enjoy the view. During the wet season, when the river water rises, people can enter the landscape platform 500 to enjoy the view. This enhances the interactivity of the main body of the slope protection 100 and further improves its landscape effect.

[0059] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments.
