Description

Technical Field

[0001] This application relates to the field of water conservancy engineering technology, and in particular to an ecological revetment structure. Background Technology

[0002] Ecological bank protection structure (also known as ecological slope protection structure) is a comprehensive protection system used to prevent slope instability and soil erosion, while restoring and improving the ecological environment of riverbank slopes.

[0003] Ecological bank protection structures typically involve laying engineering materials (stones, eco-bricks) and vegetation on riverbank slopes to achieve both mechanical reinforcement and ecological functionality. Current technologies generally include eco-brick bank protection structures, eco-bag bank protection structures, and gabion bank protection structures.

[0004] When gabion netting is used in ecological revetment structures, the gabions consist of wire mesh cages and filler material, typically boulders. In existing technologies, the spacing between the boulders within the cages is small, resulting in less soil remaining between them, which is detrimental to vegetation rooting and growth. Particularly on the water-facing side of the gabion, soil is difficult to retain, hindering vegetation growth on the gabion surface and thus impacting the ecological function of the revetment structure and the ecological environment of both riverbanks. Utility Model Content

[0005] In order to balance the reinforcement and ecological functions of the ecological revetment structure, this application provides an ecological revetment structure.

[0006] This application provides an ecological bank protection structure, which adopts the following technical solution: An ecological revetment structure includes a stepped base layer on the riverbank slope, upon which the ecological revetment structure is installed. It comprises several gabions laid on the base layer. Each gabion consists of a wire mesh cage, boulders, a concrete frame, and partitions. The boulders and concrete frame are filled within the wire mesh cage. The concrete frame is positioned on the water-facing side of the gabion, while the boulders are positioned on the water-repellent side. Each concrete frame has a receiving chamber for containing soil. A first connecting hole is provided on the water-facing side of the concrete frame, communicating with the receiving chamber. The partitions cover the first connecting hole and have several gaps to allow vegetation to attach to the soil.

[0007] By adopting the above technical solution, in this application, the boulders and the concrete frame are set together in the gabion. The boulders are relatively heavy, which makes the gabion have a mechanical reinforcement effect on the riverbank and improve the stability of the riverbank slope. The concrete frame is set on the water-facing side of the gabion to facilitate the attachment and growth of vegetation, thereby improving the ecological function of the bank protection structure. That is, through the synergistic cooperation of the boulders and the concrete frame, the gabion can take into account both reinforcement and ecological functions.

[0008] Optionally, it also includes a separating net, which is fixedly connected between the separating net facility and the boulders and the concrete frame, and the separating net is fixedly connected to the wire mesh cage.

[0009] By adopting the above technical solution, the boulders are separated from the concrete frame using a separating net, thereby reducing the collision between the boulders and the concrete frame when filling the net cage, and reducing the risk of damage to the concrete frame.

[0010] Optionally, at least two first connecting holes are spaced apart along the horizontal direction; the concrete frame is provided with a reinforcing rod, which is disposed in the receiving chamber and fixedly connected to the inner wall of the receiving chamber, and the reinforcing rod is disposed between the two first connecting holes.

[0011] By adopting the above technical solution, the reinforcing rod is used to improve the overall rigidity of the concrete frame, thereby increasing the strength of the concrete frame; thus, when filling the gabion with rubble, the risk of damage to the concrete frame can be reduced.

[0012] Optionally, the gabion may also include a coconut fiber mat, which is disposed on the side of the partition closer to the soil body.

[0013] By adopting the above technical solution, the gaps between the fibers inside the coconut fiber mat provide a stable attachment space for plant seeds, which is conducive to improving the growth of vegetation on the surface of the gabion mesh and increasing the vegetation coverage in the ecological revetment structure.

[0014] Optionally, the partition is a dustproof net.

[0015] By adopting the above technical solution, the dustproof net has a certain structural strength, so that the dustproof net can prevent soil from falling out from the first connecting hole; and the dustproof net has a lot of pores to allow vegetation to grow and attach.

[0016] Optionally, several concrete frame bodies are stacked on top of each other, with a second connecting hole at the bottom of each concrete frame body and a third connecting hole at the top of each concrete frame body. Both the second connecting hole and the third connecting hole are connected to the receiving chamber.

[0017] By adopting the above technical solution, the concrete frame is provided with a second connecting hole and a third connecting hole, so that the soil can be installed through several concrete frames to facilitate the growth of plant roots.

[0018] Optionally, the concrete frame further includes a fourth connecting hole and a fifth connecting hole, which are disposed on both sides of the third connecting hole; the fourth connecting hole and the fifth connecting hole are used to connect the receiving chambers of adjacent concrete frames.

[0019] By adopting the above technical solution, the concrete frame is provided with a fourth connecting hole and a fifth connecting hole, so that the receiving chambers of the same row of concrete frames are connected to facilitate the growth of plant roots.

[0020] Optionally, the concrete frame further includes a sixth connecting hole, which is disposed opposite to the first connecting hole and communicates with the receiving chamber.

[0021] By adopting the above technical solution, a sixth connecting hole is opened in the concrete frame, which is conducive to the extension of the roots of the vegetation towards the rocks, thereby promoting the growth of the vegetation and improving the ecological effect of the revetment structure.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. In this application, the boulders and the concrete frame are placed together in the gabion. The boulders are relatively heavy, which makes the gabion have a mechanical reinforcement effect on the riverbank and improve the stability of the riverbank slope. The concrete frame is provided on the water-facing side of the gabion to facilitate the attachment and growth of vegetation, thereby improving the ecological function of the bank protection structure. That is, through the synergistic cooperation of the boulders and the concrete frame, the gabion can take into account both reinforcement and ecological functions. 2. By using a separating net to separate the boulders from the concrete frame, the collision between the boulders and the concrete frame can be reduced when filling the net box, thus reducing the risk of damage to the concrete frame. 3. The gaps between the fibers inside the coconut fiber mat provide a stable attachment space for plant seeds, which is conducive to improving the growth of vegetation on the surface of the gabion mesh and increasing the vegetation coverage in the ecological revetment structure.

[0032] The following is in conjunction with the appendix Figure 1 -8 provides further details regarding this application.

[0033] This application discloses an ecological bank protection structure. (Refer to...) Figure 1 The riverbank slope is provided with a stepped foundation layer 1, which is a soil layer cleared by mechanical equipment on both sides of the river. In this embodiment, the ecological slope protection structure is set on the foundation layer 1 to improve the stability of the riverbank slopes and reduce soil erosion on both sides of the river.

[0034] Reference Figure 1 The ecological revetment structure includes several gabions 2, which are laid on the foundation layer 1. In this embodiment, the gabions 2 are also laid on the foundation layer 1 in a stepped manner.

[0035] Reference Figure 2 and Figure 5 The gabion 2 includes a wire mesh cage 21, boulders 22, a concrete frame 23, a partition net 24, a coconut fiber mat 26, and a partition 25.

[0036] Reference Figures 2 to 5Several boulders 22 and several concrete frame bodies 23 are filled into the gabion 21. The concrete frame bodies 23 are located on the water-facing side of the gabion 2, and the boulders 22 are located on the water-repellent side of the gabion 2. In this embodiment, the concrete frame bodies 23 are stacked. A separating net 24 is placed between the boulders 22 and the concrete frame bodies 23, and the separating net 24 is fixedly connected to the gabion 21. In this embodiment, the gabion 21 and the separating net 24 are woven from high-strength galvanized steel wire. In this embodiment, the workers stack the concrete frame bodies 23 in the gabion 21; then, the workers weave and fix the separating net 24 to the gabion 21; finally, the workers fill the gabion 21 with boulders 22. When filling the gabion 21 with boulders 22, the workers can fill the gaps between the boulders 22 with soil to increase the soil content in the gabion 2. By using the separating net 24 to separate the boulders 22 from the concrete frame 23, the collision between the boulders 22 and the concrete frame 23 can be reduced when filling the net box 21 with boulders 22, thus reducing the risk of damage to the concrete frame 23.

[0037] Reference Figure 6 and Figure 7 The concrete frame 23 is a hexahedral structure and is a reinforced concrete structure, which gives the concrete frame 23 a certain structural strength; the concrete frame 23 has a receiving chamber 237, which is used to receive the soil body 3.

[0038] Reference Figure 7 In this embodiment, the concrete frame 23 is a cuboid structure. A first connecting hole 231 is provided on the water-facing side of the concrete frame 23, communicating with the receiving chamber 237; at least two first connecting holes 231 are spaced apart along the horizontal direction. A second connecting hole 232 is provided at the bottom of the concrete frame 23, and a third connecting hole 233 is provided at the top of the concrete frame 23, both communicating with the receiving chamber 237. The concrete frame 23 also includes a fourth connecting hole 234 and a fifth connecting hole 235, located on either side of the third connecting hole 233; the fourth connecting hole 234 and the fifth connecting hole 235 are used to connect the receiving chambers 237 of adjacent concrete frame 23s. The concrete frame 23 also includes a sixth connecting hole 236, which is opposite to the first connecting hole 231 and communicates with the receiving chamber 237.

[0039] The concrete frame 23 has a second connecting hole 232 and a third connecting hole 233, allowing the soil mass 3 to be installed through several concrete frame bodies 23. The concrete frame 23 also has a fourth connecting hole 234 and a fifth connecting hole 235, connecting the receiving chambers 237 of the same row of concrete frame bodies 23. A sixth connecting hole 236 is provided in the concrete frame 23, which facilitates the extension of vegetation roots towards the boulders 22. In other words, by setting several connecting holes around the outer perimeter of the concrete frame 23, vegetation growth is promoted, improving the ecological effect of the revetment structure.

[0040] Reference Figure 7 The concrete frame 23 is equipped with reinforcing rods 238, which are disposed in the receiving chamber 237 and fixedly connected to the inner peripheral wall of the receiving chamber 237. The reinforcing rods 238 are located between the two first connecting holes 231. The reinforcing rods 238 are used to improve the overall rigidity of the concrete frame 23, thereby increasing its strength; thus, when filling the gabion 21 with rubble 22, the risk of damage to the concrete frame 23 can be reduced.

[0041] Reference Figure 8 The partition 25 covers the first connecting hole 231 and has several gaps to allow vegetation to attach to the soil body 3. In this embodiment, the partition 25 is a dustproof net. The dustproof net has a certain structural strength, so it can prevent the soil body 3 from falling out of the first connecting hole 231; and the dustproof net has a large number of pores to allow vegetation to grow and attach.

[0042] Reference Figure 8 The coconut fiber mat 26 is placed on the side of the partition 25 near the soil body 3; the gaps between the fibers inside the coconut fiber mat provide a stable attachment space for plant seeds, which is conducive to improving the growth of vegetation on the surface of the gabion net and increasing the vegetation coverage in the ecological revetment structure.

[0043] The implementation principle of an ecological revetment structure in this application embodiment is as follows: In this application, the boulders 22 and the concrete frame 23 are placed together in the gabion 21. The boulders 22 are relatively heavy, which gives the gabion 2 a mechanical reinforcement effect on the riverbank and improves the stability of the riverbank slope. The concrete frame 23 is provided on the water-facing side of the gabion 2. The internal chambers 237 of the concrete frame 23 contain a large amount of soil to facilitate the attachment and growth of vegetation, thereby improving the ecological function of the revetment structure.

[0044] In summary, in this embodiment, the gabion 2 achieves both reinforcement and ecological functions through the coordinated operation of the boulders 22 and the concrete frame 23.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
