Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ecological environment equipment, in particular to an ecological river bank protection. BACKGROUND

[0002] In river regulation engineering, bank protection plays a crucial role. Traditional river bank protection structures have various forms, but their drawbacks have gradually emerged. Many traditional bank protections use hard materials such as concrete and mortar stones. These materials can resist water erosion to some extent and ensure the stability of the river, but they block the material exchange between the river water and the surrounding soil and groundwater, disrupting the natural ecological cycle. This makes the aquatic organisms in the river lose their suitable habitat, significantly reduces biodiversity, and reduces the self-repairing ability of the river ecosystem.

[0003] For the above related technologies, the inventors found that many existing devices on the market do not have a dedicated planting hole, or the designed planting space is unreasonable, making it difficult for plants to grow on the bank protection. This makes it difficult for the river to use plant roots to reinforce the soil and use plants for ecological restoration, thereby affecting the integrity of the river ecosystem. Most existing devices use materials and structures with strong sealing, which block the material exchange between the river water and the surrounding soil and groundwater, break the natural ecological cycle, and make aquatic organisms lose their suitable living environment, resulting in reduced biodiversity.

DETAILED DESCRIPTION

[0024] The bottom stone cage assembly 11 and the top stone cage assembly 12 further include a main filler 109, a secondary filler 110 and an aesthetic filler 111, the main filler 109 is filled in the inside of the cage formed by the hollow hexagonal cage body 101, the first side cover 103 and the second side cover 106, the secondary filler 110 is filled in the gap of the main filler 109, and the aesthetic filler 111 is filled in the gap between the secondary filler 110 and the main filler 109.

[0025] The cross-sectional shape of the first side cover 103 and the second side cover 106 is completely same as that of the hollow hexagonal cage body 101, and the thickness of the hexagonal protrusion 104 is equal to the depth of the hexagonal groove 108.

[0026] The hole diameter of the first internal threaded hole 105 is equal to that of the second internal threaded hole 107, and a long rod bolt is threadedly sleeved in the inside of the first internal threaded hole 105 and the second internal threaded hole 107.

[0027] The diameters of the main filler 109, the secondary filler 110 and the aesthetic filler 111 are greater than the hole diameter of the planting hole 102, the main filler 109 is composed of an outer multi-void hollow spherical skeleton and an inner perlite, and the perlite has the characteristics of water absorption and weight increase.

[0028] The secondary filler 110 is vermiculite, and the diameter of the secondary filler 110 is smaller than that of the primary filler 109; the ornamental filler 111 is cobblestone, and the diameter of the ornamental filler 111 is smaller than that of the secondary filler 110.

[0029] It needs to be further explained that:

[0030] The ecological river revetment stone cage 1 is composed of a bottom layer stone cage assembly 11 and a top layer stone cage assembly 12, which are laid on the river slope and can be transversely spliced and assembled. The hollow hexagonal cage body 101 in the assembly is the main frame, which is installed in the river slope installation groove to provide basic support for the entire revetment. The first side cover 103 and the second side cover 106 close the two sides of the cage body to form a complete cage body with the hollow hexagonal cage body 101. The hexagonal protrusion 104 and the hexagonal groove 108 cooperate with each other to realize the vertical connection of the bottom layer and the top layer assembly. The first inner threaded hole 105 and the second inner threaded hole 107 are fastened by a long rod bolt to make the entire structure connected tightly and stably resist water flow erosion and other external forces, thereby ensuring the stability of the river revetment.

[0031] The planting hole 102 on the side of the hollow hexagonal cage body 101 creates conditions for plant growth. Plants grow in the planting hole 102, and their root systems penetrate deep into the soil, effectively reinforcing the slope soil and preventing water and soil loss. The presence of plants also provides habitats for aquatic organisms to breed, promoting the balance of the river ecosystem and increasing biodiversity. The perlite in the primary filler 109 can absorb water, and the vermiculite in the secondary filler 110 can retain water and fertilizer, which provides a good living environment for plant growth and further strengthens the ecological restoration function, making the river ecology more healthy and sustainable.

[0032] The primary filler 109, the secondary filler 110, and the ornamental filler 111 are filled in layers, not only improving the stability of the revetment structure but also bringing aesthetic effects. The multi-void hollow spherical skeleton of the primary filler 109 provides support, and the internal perlite absorbs water and increases weight. The vermiculite in the secondary filler 110 fills the gaps between the primary filler 109, enhancing the compactness. The ornamental filler 111 uses cobblestone, greatly improving the aesthetics of the river revetment on the basis of structural stability, making the surrounding environment of the river more pleasant. Moreover, the transverse splicing and assembly characteristics of the stone cage assembly improve construction efficiency and facilitate the construction and maintenance of the revetment.

[0033] The working principle of the above embodiment is:

[0034] Firstly, the bottom layer of gabion assembly 11 is laid in the pre-dug installation slot on the river slope, and the hollow hexagonal cage body 101 serves as a foundation frame to provide support for the subsequent structure. The top layer of gabion assembly 12 is vertically connected with the bottom layer of gabion assembly 11 by the cooperation of the hexagonal protrusions 104 and the hexagonal recesses 108, and a multi-layer revetment structure is initially constructed. At the same time, the first inner threaded hole 105 and the second inner threaded hole 107 on the first side cover 103 and the second side cover 106 are fastened by long rod bolts to ensure that the entire revetment gabion structure is tightly connected and firmly anchored on the river slope to resist the initial impact of the water flow.

[0035] Secondly, the main filler 109 is filled in the built gabion assembly, and the outer multi-gap hollow spherical skeleton of the main filler 109 provides a basic support framework. The internal perlite increases in weight after encountering water due to its water absorption characteristics, making the revetment gabion more firmly rooted in the river slope.

[0036] Next, the secondary filler 110 of vermiculite is filled in the gaps of the main filler 109. Vermiculite has good water and fertilizer retention performance, which not only further fills the gaps and enhances the compactness of the structure, but also provides a suitable moisture and nutrient environment for subsequent plant growth, ensuring sufficient water and nutrient supply for plants during growth.

[0037] Next, the aesthetic filler 111 of pebbles is filled in the gaps between the secondary filler 110 and the main filler 109. Pebbles not only beautify the river revetment, but also to some extent, buffer the impact of water flow on the revetment, further improving the protection performance of the revetment, making the surrounding environment of the river more beautiful and safe.

[0038] Finally, the planting holes 102 on the side of the hollow hexagonal cage body 101 provide space for plant growth. Plants grow and root in the planting holes 102, with root systems deep into the soil, reinforcing the slope soil and preventing soil erosion. At the same time, the growth of plants also provides habitats for aquatic organisms, promoting the balance of river ecosystem and the increase of biodiversity, achieving the function of ecological restoration, making the river ecological environment more healthy and sustainable.

[0039] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made in accordance with the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
