AI Technical Summary
In existing river ecological slope protection structures, ecological gabions are difficult to retain soil, making it difficult to fix the roots of vegetation. Porous bio-bricks are easily washed away by river water, leading to soil loss and making it difficult for vegetation to grow stably in the river.
The system employs a frame structure, comprising an absorbent body and a filler body. The absorbent body is used to fix plant seeds and young roots, while the filler body is used for root growth and nutrient supply. Combined with a steel mesh cage to fix the filler body, the system improves the fixation effect and coverage of the vegetation.
In the early stages of vegetation growth, seeds and young roots are fixed in the absorbent body, and in the later stages, the roots are fixed in the filler body, which increases vegetation coverage and reduces the risk of soil erosion, thereby enhancing the aesthetics and ecological function of riverbank protection.

Abstract
Description
Technical Field
[0001] This application relates to the field of water conservancy engineering technology, and in particular to a river ecological slope protection structure. Background Technology
[0002] River ecological slope protection structure is a technology that integrates knowledge from disciplines such as engineering mechanics, soil science, ecology, and botany to support river slopes, forming a comprehensive slope protection system composed of plants or a combination of engineering and plants.
[0003] In existing technologies, riverbank ecological protection structures include ecological gabion slope protection, porous ecological brick slope protection, and ecological bag slope protection. In ecological gabion slope protection, the large gaps between the stones make it difficult for soil to remain inside the gabions, and early-stage vegetation roots struggle to attach to the gabions. In porous bio-brick slope protection, the soil within the bio-bricks is insufficient to withstand river erosion, leading to soil loss and difficulty in vegetation retention. Utility Model Content
[0004] In order to improve the anchoring effect of vegetation in river ecological slope protection structures and increase the vegetation coverage in river slope protection structures, this application provides a river ecological slope protection structure.
[0005] This application provides a river ecological slope protection structure, which adopts the following technical solution:
[0006] An ecological riverbank protection structure, along the direction away from the riverbank slope, sequentially includes a base layer and a vegetation layer, with the vegetation layer fixed on the base layer; the vegetation layer includes several vegetation units, which are laid on the base layer; each vegetation unit includes a frame, a filler, and an absorbent; the frame has a receiving chamber, and each of the six sides of the frame has a connecting hole; the inner side of the frame is symmetrically provided with limiting protrusions, two of which divide the receiving chamber into a first receiving chamber and a second receiving chamber; the first receiving chamber is located on the water-facing side of the vegetation unit and is used to receive the absorbent, which is used for adsorption and fixation of the vegetation; the second receiving chamber is used to receive the filler, which is a mixture of gravel and soil.
[0007] By adopting the above technical solution, in the early stage of vegetation growth, the absorbent bodies on the water-facing side of the frame facilitate the adsorption and fixation of plant seeds and young roots. In the later stage of vegetation growth, the plant roots grow into the filler body, where the stones help fix the vegetation, and the soil in the filler body can provide nutrients for the vegetation, allowing the vegetation to grow on the outer and upper surfaces of the frame. In other words, by setting absorbent bodies and filler bodies within the frame, the vegetation can be fixed to these bodies, thereby improving the fixation effect of vegetation in the riverbank ecological slope protection structure and increasing the vegetation coverage rate of the riverbank protection structure.
[0008] Optionally, the absorbent includes a coil pad for fixing the roots of the vegetation.
[0009] By adopting the above technical solution, high-temperature PVC raw material solution is processed into coils through a spinneret to form coil pads. These coil pads have excellent corrosion resistance and a long service life. The coil pads have abundant internal gaps to allow for root adsorption and fixation of vegetation; this facilitates the attachment of vegetation to the side walls of the frame structure, increasing the vegetation coverage in the riverbank ecological slope protection structure and enhancing the aesthetics of the river.
[0010] Optionally, the adsorbent further includes a coconut fiber pad, wherein the fiber loop pad and the coconut fiber pad are stacked together, and the coconut fiber pad is disposed on the water-facing side of the adsorption unit.
[0011] By adopting the above technical solution, the coconut fiber mat has small gaps inside, which facilitates the adsorption and fixation of plant seeds and young vegetation onto the coconut fiber mat, thereby improving the vegetation coverage in the riverbank protection structure.
[0012] Optionally, a distance is provided between the limiting protrusion, the adsorbent, and the upper surface of the frame, and the filler is disposed on the side of the adsorbent away from the ground.
[0013] By adopting the above technical solution, the limiting protrusion and the adsorbent are lower than the upper surface of the frame, so that the filler can cover the upper surface of the frame, so that the vegetation can cover the upper surface of the frame, thereby improving the aesthetics of the river ecological slope protection structure.
[0014] Optionally, the area of the horizontal cross-section of the first receiving chamber decreases along the vertically downward direction.
[0015] By adopting the above technical solution, the area of the horizontal cross-section of the first receiving chamber decreases, so that when the vegetation withers seasonally and the coconut fiber mats rot, workers can remove the silk ring mats from the first receiving chamber for cleaning, thus removing the decaying vegetation from the frame and improving the aesthetics of the waterway. Subsequently, workers can place new coconut fiber mats and silk ring mats in the first receiving chamber to facilitate the growth of vegetation in the next season.
[0016] Optionally, the vegetation layer also includes tie bolts, and the frame body has mounting holes for the tie bolts to pass through, and adjacent frame bodies are fixedly connected by the tie bolts.
[0017] By adopting the above technical solution, several frame structures are connected into a whole by tie bolts, so as to improve the continuity and integrity of the river ecological slope protection structure and enhance the aesthetics of the river.
[0018] Optionally, the adsorption unit further includes a steel mesh cage disposed in the second receiving chamber, the steel mesh cage being used to receive the filler.
[0019] By adopting the above technical solution, a steel mesh cage is installed in the second receiving chamber to fix the fill stones and soil in the filling body, thereby reducing the risk of fill stones and soil being lost from the connecting holes.
[0020] Optionally, the water-facing surface of the frame body is provided with several block-shaped protrusions.
[0021] By adopting the above technical solution, several block-shaped protrusions are set on the water-facing surface of the frame, which can improve the three-dimensionality and aesthetics of the river ecological slope protection structure when the vegetation withers.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. In the early stages of vegetation growth, the absorbent structures on the water-facing side of the frame facilitate the adsorption and fixation of plant seeds and young roots. In the later stages of vegetation growth, the roots grow into the filler, where the stones further stabilize the vegetation. The soil in the filler provides nutrients, allowing the vegetation to grow on the outer and upper surfaces of the frame. In other words, by incorporating absorbent structures and filler within the frame, the vegetation can be fixed to these structures, thereby improving the fixation effect of the vegetation in the riverbank ecological slope protection structure and increasing the vegetation coverage rate within the structure.
[0024] 2. The horizontal cross-sectional area of the first receiving chamber decreases gradually, so that when the vegetation withers seasonally and the coconut fiber mats rot, workers can remove the silk ring mats from the first receiving chamber for cleaning, thus removing the decaying vegetation from the frame and improving the aesthetics of the waterway. Subsequently, workers can place new coconut fiber mats and silk ring mats in the first receiving chamber to facilitate the growth of vegetation in the next season.
[0025] 3. By installing a steel mesh cage in the second receiving chamber, the fill stones and soil in the filling material are fixed in place, thereby reducing the risk of fill stones and soil being lost from the connecting holes. Attached Figure Description

[0033] The following is combined with Figure 1 -6 provides further detailed information about this application.
[0034] This application discloses an ecological riverbank protection structure. (Refer to...) Figure 1 Along the direction away from the riverbank slope, the riverbank ecological slope protection structure sequentially includes a base layer 1 and a vegetation layer 2, with the vegetation layer 2 fixed on the base layer 1. The vegetation layer 2 includes several vegetation units 3, which are laid on the base layer 1. In this embodiment, the riverbank slope is stepped, and the base layer 1 is a concrete structure; in other embodiments, the riverbank slope can also be a sloping structure, and the base layer 1 can be a compacted soil structure.
[0035] Reference Figure 2 and Figure 3 The vegetation unit 3 includes a frame 31, tie bolts 32, filler 33, and absorbent 34.
[0036] Reference Figure 2 and Figure 3The frame body 31 is fixedly connected to the base layer 1 by anchor bolts. The frame body 31 has mounting holes 313 for tie bolts 32 to pass through. Adjacent frame bodies 31 are fixedly connected by tie bolts 32. Thus, multiple frame bodies 31 are connected into a whole and the frame body 31 is fixed on the river slope, reducing the risk of vegetation units 3 in local areas being washed away.
[0037] Reference Figure 2 and Figure 3 Meanwhile, the frame body 31 has a receiving chamber 311, and all six sides of the frame body 31 have connecting holes 312; the receiving chamber 311 is used to fix vegetation to improve the ecological function of the riverbank slope; the connecting holes 312 on the six sides of the frame body 31 are used for water to pass through, so as to facilitate the growth of vegetation.
[0038] Reference Figure 3 In addition, the water-facing surface of the frame 31 is provided with several block-shaped protrusions 314 to enhance the three-dimensionality of the vegetation unit 3 and improve the aesthetics of the river ecological slope protection structure.
[0039] Reference Figure 3 and Figure 4 The frame 31 has symmetrically provided limiting protrusions 35 on its inner side. The two limiting protrusions 35 divide the receiving chamber 311 into a first receiving chamber 3111 and a second receiving chamber 3112. The first receiving chamber 3111 is located on the water-facing side of the vegetation unit 3. The first receiving chamber 3111 is used to receive the adsorbent 34, which is used for adsorption by the vegetation. The second receiving chamber 3112 is used to receive the filler 33, which is a mixture of gravel and soil.
[0040] Reference Figure 4 In this embodiment, the adsorbent 34 includes a coil pad 341 and a coconut fiber pad 342, which are stacked together. The coconut fiber pad 342 is disposed on the water-facing side of the adsorption unit. The coil pad 341 is used to fix the roots of the vegetation, and the coconut fiber pad 342 is used to fix the seeds or seedlings of the vegetation.
[0041] High-temperature PVC raw material solution is processed into coils by a spinneret to form coil pads 341. Coil pads 341 have good corrosion resistance and a long service life.
[0042] Reference Figure 4In this embodiment, the area of the horizontal cross-section of the first receiving chamber 3111 decreases along the vertically downward direction. Therefore, when the vegetation withers seasonally and the coconut fiber mat 342 rots, workers can remove the silk ring mat 341 from the first receiving chamber 3111 for cleaning, thus removing the decaying vegetation from the frame 31 and improving the aesthetics of the waterway. Subsequently, workers can place new coconut fiber mats 342 and silk ring mats 341 into the first receiving chamber 3111 to facilitate the growth of vegetation in the next season.
[0043] The implementation principle of a river ecological slope protection structure according to an embodiment of this application is as follows:
[0044] In the early stage of vegetation growth, the adsorbent 34 on the water-facing surface of the frame 31 is conducive to the adsorption and fixation of vegetation seeds and young roots; while in the later stage of vegetation growth, the roots of the vegetation grow into the filling body 33, the stones in the filling body 33 are conducive to fixing the vegetation, and the soil in the filling body 33 can provide nutrients for the vegetation, so that the vegetation can grow on the outer facade and upper surface of the frame 31.
[0045] The coconut fiber mat 342 has small gaps inside to facilitate the adsorption and fixation of plant seeds and young vegetation onto the mat 342, thereby increasing the vegetation coverage in the riverbank protection structure. The silk ring mat 341 has abundant gaps inside to allow plant roots to adsorb and fix it, thereby facilitating the fixation of vegetation to the side wall of the frame 31, increasing the vegetation coverage in the riverbank ecological protection structure, and improving the aesthetics of the river.
[0046] That is, by setting up an absorbent 34 and a filler 33 in the frame 31, the vegetation can be fixed on the absorbent 34 and the filler 33; thereby improving the fixing effect of vegetation in the river ecological slope protection structure and increasing the vegetation coverage rate in the river slope protection structure.
[0047] Example 2
[0048] The difference between Example 2 and Example 1 is as follows:
[0049] In this embodiment, a distance is provided between the limiting protrusion 35, the adsorbent 34, and the upper surface of the frame 31, and the filler 33 is disposed on the side of the adsorbent 34 away from the ground. The limiting protrusion 35 and the adsorbent 34 are lower than the upper surface of the frame 31, so that the filler 33 can cover the upper surface of the frame 31, so that vegetation can cover the upper surface of the frame 31, thereby improving the aesthetics of the river ecological slope protection structure.
[0050] Example 3
[0051] The difference between Example 3 and Example 1 is as follows:
[0052] The adsorption unit also includes a steel mesh cage 4, which is disposed in the second receiving chamber 3112 and is used to receive the filler 33. In this embodiment, the steel mesh cage 4 is used to fix the filler stones and soil in the filler 33 to reduce the risk of the filler stones and soil being lost from the connecting hole 312.
[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
