Description
Technical Field
[0001] The utility model relates to the technical field of revetment structures, in particular to an ecological channel of a revetment structure. Background Art
[0002] Adding an ecological bin to the revetment structure can, on the one hand, beautify the revetment structure, and on the other hand, achieve the "integration of water and soil" on both sides of the revetment structure without affecting the original ecological environment. However, in the prior art, the "integration of water and soil" cannot be fully achieved. As shown in the attached Figure 11 figure, an ecological bin is provided on the revetment structure 100, and dislocation holes 100a are formed on the water-facing surface and the soil-facing surface to prevent soil erosion. An energy dissipation part 100b that can prevent water flow from scouring the soil is arranged in the dislocation holes 100a to reduce the direct action of water flow on the soil. And through the arrangement of the filter layer 100c, the water body can be filtered and the soil can be blocked. The above structure can prevent soil erosion, but also prevents the entry and exit of animals. Especially for amphibians, after entering the dislocation holes, they cannot pass through the filter layer and enter the soil, and it is also not easy to move from the low position to the high position of the dislocation holes, that is, they cannot enter the water body again and are trapped in the dislocation holes.
[0003] Therefore, although the above structure can prevent soil erosion, it cannot truly maintain the biodiversity of water and soil organisms in the original environment, nor is it easy to maintain ecological balance. Summary of the Utility Model
[0004] The purpose of the utility model is to provide an ecological channel of a revetment structure. By setting a wave-dissipating structure with a pore passage, animals can pass through, and the wave-dissipating structure can block the water flow, which can avoid the water flow passing through the main channel and the pore passage unobstructed and directly acting on the soil on the other side of the revetment structure. It has a good anti-scouring effect and can prevent soil erosion.
[0005] To achieve the above purpose, the technical scheme adopted by the utility model is: an ecological channel of a revetment structure, including a main channel arranged on the revetment structure and penetrating the revetment structure, and a wave-dissipating structure arranged in the main channel. Pore passages are provided between the wave-dissipating structure and the inner wall of the main channel and / or inside the wave-dissipating structure body. The two ends of the pore passages are respectively communicated with both sides of the main channel. An inlet and an outlet are respectively formed at one end of the pore passage close to the water-facing surface and one end close to the soil-facing surface. At least a part of the projection surface of the inlet along the central axis direction of the main channel falls on the wave-dissipating structure.
[0006] As a further optimization, the entire projection surface of the inlet along the central axis direction of the main channel falls on the wave-dissipating structure, avoiding the water flow directly acting on the soil without any obstruction after entering the pore passage from the inlet.
[0007] As a further optimization, the wave dissipating structure is a spiral plate, and the side wall of the spiral plate is connected to the inner wall of the main channel.
[0008] As a further optimization, the spiral plate is discontinuous.
[0009] As a further optimization, the wave dissipating structure includes at least a pair of partition plates, and a pair of the partition plates are arranged on the inner wall of the main channel in a staggered manner.
[0010] As a further optimization, the partition plates are arranged obliquely, and the oblique state can have a larger working surface to contact the water flow for wave dissipation.
[0011] As a further optimization, the partition plates have an arc surface structure, which has a larger contact surface with the water flow and can realize water flow guiding on the basis of wave dissipation.
[0012] As a further optimization, a branch channel is further included. The branch channel is arranged beside the main channel, and the two are connected through a side hole arranged on the side wall of the main channel. An anti-filtering component is arranged in the branch channel. The anti-filtering component includes a frame with a hollow structure and an anti-filtering layer arranged in the frame. The anti-filtering layer covers the side hole.
[0013] As a further optimization, the frame includes a front hollow partition plate and a rear hollow partition plate. The front hollow partition plate is arranged on the side close to the water-facing surface in the branch channel, the rear hollow partition plate is arranged on the side close to the soil-facing surface in the branch channel, and the anti-filtering layer is arranged between the front hollow partition plate and the rear hollow partition plate.
[0014] As a further optimization, the frame includes a drawer plate and a front hollow partition plate. The drawer plate is slidably arranged in the branch channel, and at least one side of the drawer plate close to the soil-facing surface has a hollow structure. The front hollow partition plate is arranged on the side close to the water-facing surface in the branch channel, and the anti-filtering layer is arranged on the drawer plate.
[0015] As a further optimization, the branch channel is located below the main channel, and the water flow can enter the branch channel from the main channel by its own gravity.
[0016] As a further optimization, one end of the main channel close to the water-facing surface and / or one end close to the soil-facing surface is flared, which can induce animals to enter the main channel.
[0017] As a further optimization, an extension pipe inclined to the central axis of the main channel is arranged at one end of the main channel close to the water-facing surface and / or one end close to the soil-facing surface. In particular, an extension pipe extending downward and opening downward is arranged on the side of the soil-facing surface, which is more beneficial to preventing soil erosion.
[0018] As a further optimization, the main channel has the same inner diameter and its central axis is a straight line, which facilitates the processing and forming of the main channel on the revetment structure.
[0019] As a further optimization, the included angle between the central axis of the main channel and the horizontal plane is α, where α ≤ 20°. The nearly horizontal state of the main channel helps animals move inside it.
[0020] Compared with the prior art, the utility model has the following beneficial effects:
[0021] 1. By providing a wave-dissipating structure with a pore passage, animals can be allowed to enter. In particular, for amphibians such as frogs, they can freely move back and forth between the water-facing side and the soil-facing side of the revetment structure, truly realizing the function of an ecological channel.
[0022] 2. The wave-dissipating structure can block the water flow, preventing the main body of the water flow from directly acting on the soil on the other side of the revetment structure after passing through the main channel and the pore passage without obstruction, and having a good anti-scouring effect to prevent soil erosion.
[0023] 3. By providing a branch channel connected to the main channel and arranging an anti-filter layer in the branch channel, the water flow entering the main channel can diffuse into the branch channel to disperse the water flow for auxiliary wave dissipation and prevent soil erosion.

[0035] The following are specific embodiments of the present utility model and in conjunction with the accompanying drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.
[0036] As Figure 1 and 2 shown, an ecological passage of a revetment structure includes a main passage 101 provided on the revetment structure 100 and penetrating the revetment structure 100, and a wave-dissipating structure 10 provided in the main passage 101. A pore passage 101' is provided between the wave-dissipating structure 10 and the inner wall of the main passage 101 and / or inside the wave-dissipating structure 10 itself. The two ends of the pore passage 101' are respectively communicated with both sides of the main passage 101. An inlet 111' and an outlet 111'' are respectively formed at one end close to the water-facing side and one end close to the soil-facing side of the pore passage 101'. At least a partial projection plane of the inlet 111' along the central axis direction of the main passage 101 falls on the wave-dissipating structure 10.
[0037] Compared with the prior art, on the one hand, the present utility model can prevent the main body of the water flow from directly acting on the soil on the other side of the revetment structure 100 after passing through the main passage 101 and the pore passage 101' without obstruction by blocking the water flow with the wave-dissipating structure 10, and a good anti-erosion effect can be achieved through the blocking effect. On the other hand, the pore passage 101' of the wave-dissipating structure 10 allows animals to enter and move therein. Especially for amphibians such as frogs, they can pass through the pore passage 101' and freely travel back and forth between the water-facing side and the soil-facing side of the revetment structure, truly realizing the function of the ecological passage.
[0038] More specifically, for the wave-dissipating structure 10 to achieve the anti-erosion effect on the water flow, after the water flow enters the main channel 101, it then enters the pore channel 101' through the inlet 111'. During this process, the wave-dissipating structure beside the inlet 111' will first eliminate part of the impact of the water flow. When the water flow flows in the pore channel 101', since the projection of the inlet 111' along the central axis direction of the main channel 101 at least partially falls on the wave-dissipating structure, the water flow entering the pore channel 101' can be blocked by the wave-dissipating structure again to disperse its impact kinetic energy and cannot directly impact the soil. Therefore, after the water flow is blocked by the wave-dissipating structure once or multiple times as described above, its impact kinetic energy is greatly dispersed or consumed, thus achieving an excellent anti-erosion effect. Similarly, the soil can be on the side of the main channel 101 close to the soil-facing surface or enter the main channel 101, but it will also be blocked by the wave-dissipating structure beside the outlet 111'' on the pore channel 101' or be blocked by the wave-dissipating structure inside the pore channel 101'. It will not be easily carried out of the pore channel 101 from the soil-facing surface, enter the main channel, and then reach the water body. Therefore, based on the above anti-erosion effect on the water flow and the blocking effect of the soil by the wave-dissipating structure, it is possible to better prevent soil erosion on the basis of allowing animals (especially amphibians) to enter and freely travel between the water-facing surface and the soil-facing surface of the revetment structure 100.
[0039] To better achieve the wave-dissipating effect and the anti-soil-loss effect, it is set that the entire projection surface of the inlet 111' along the central axis direction of the main channel 101 falls on the wave-dissipating structure 10, which can prevent the projection of the inlet 111' from directly covering the outlet 111'' and avoid the water flow from entering the other side of the main channel 101 in a straight line without obstruction and impacting the soil.
[0040] Based on the above wave-dissipating structure 10, it can have various specific structural forms. Continuing to combine Figure 1 and 2 As shown, in an embodiment of the present invention, the wave-dissipating structure 10 is a pair of partition plates 111. The pair of partition plates 111 are arranged on the inner wall of the main channel 101 in a staggered manner. An inlet 111' is formed between the partition plate close to the water-facing side of the main channel 101 and the inner wall of the main channel 101, and an outlet 111'' is formed between the partition plate close to the soil-facing side of the main channel 101 and the inner wall of the main channel 101. Furthermore, a pore channel 101' is formed between the pair of partition plates and between the pair of partition plates and the inner wall of the main channel 101, and the entire projection surface of the two partition plates along the central axis direction of the main channel 101 falls on each other. This structure can not only achieve the wave-dissipating effect and prevent soil loss, but also allow animals (especially amphibians) to pass through.
[0041] As Figures 3 to 4As shown, in another embodiment of the present utility model, the wave-dissipating structure 10 is a spiral plate 112. The side wall of the spiral plate 112 is connected to the inner wall of the main channel 101. The inlet 111' in this structure is the open area of the entire main channel 101. After the water flow enters the main channel 101, it can flow along a spiral path (this path is also the movement path of the animal), or it can disperse after bypassing the spiral structure at the end. Combined with Figure 5 As shown, regardless of the way the water flow moves, based on the projection plane of the inlet 111' along the central axis direction of the main channel 101 falling on the wave-dissipating structure 10 (the internal structure of the spiral plate 112), the water flow can be blocked by the structure of the spiral plate 112 itself to prevent it from directly impacting the soil, thereby achieving the wave-dissipating effect.
[0042] As Figure 6 shown, the spiral plate 112 is discontinuous, that is, at least a pair of fin plates 112' are spaced apart and arranged on the inner wall of the main channel 101.
[0043] As Figure 7 and 8 shown, in another embodiment of the present utility model, the wave-dissipating structure 10 is a pair of partitions 111 which are arranged on the inner wall of the main channel 101 in a staggered manner, but they are arranged obliquely, having a larger working surface and can better block and dissipate waves. In addition, the partitions 111 have an arc-shaped structure, and on the basis of the wave-dissipating effect, the water flow can also be guided.
[0044] Continuing as Figure 7 and 8 shown, the ecological channel of the present utility model further includes a branch channel 102. Preferably, the branch channel 102 is arranged beside the main channel 101 and the two are connected through a side hole 1010 provided on the side wall of the main channel 101. An anti-filtering component 20 is provided in the branch channel 102. The anti-filtering component 20 includes a frame 21 with a hollow structure and an anti-filtering layer 22 provided in the frame 21. The anti-filtering layer 22 can be a porous rib-shaped body, such as a sponge layer, which covers the side hole 1010. On the one hand, through the branch channel 102 and the anti-filtering layer 22, the moisture on the soil-facing side can flow through the branch channel 102 to the water-facing side, and the soil is blocked from flowing out through the anti-filtering layer 22. On the other hand, after the water flow enters the main channel 101, part of the water flow can also enter the branch channel 102 through the side hole 1010 and flow and disperse in the anti-filtering layer 20. The dispersed flow of the water flow can reduce the water flow rate in the main channel 101 and can further ensure the wave-dissipating effect.
[0045] Preferably, the branch channel 102 is arranged below the main channel 101, which is convenient for the water flow to enter the branch channel 102 from the main channel 101 by its own gravity during the wave-dissipating process.
[0046] For the formation of the above structure, a through-hole can be first formed on the revetment structure 100, and a flat plate with side holes 1010 is fixedly arranged at a suitable position in the through-hole. Thus, a main channel 101 is formed on one side of the flat plate (above the flat plate), and a branch channel 102 is formed on the other side of the flat plate (below the flat plate).
[0047] More specifically, the frame 21 includes a front hollow partition 211 and a rear hollow partition 212. The front hollow partition 211 is fixedly arranged on the side close to the water-facing side in the branch channel 102, and the rear hollow partition 212 is fixedly arranged on the side close to the soil-facing side in the branch channel 102. Both of them are provided with holes 210 for forming a hollow structure. The filter layer 22 is arranged between the front hollow partition 211 and the rear hollow partition 212 and is fixed in the branch channel 102.
[0048] As Figure 9 shown, in another embodiment of the frame 21, it includes a drawer plate and a front hollow partition. The front hollow partition is arranged on the side close to the water-facing side of the branch channel 102 and has holes for forming a hollow structure. The drawer plate is similar to a drawer shape, and specifically includes a rear hollow partition 212 and a U-shaped plate 213 connected to the rear hollow partition 212. A positioning groove 200 is formed between the two for positioning and placing the filter layer 22. The drawer plate is slidably arranged in the branch channel 102, and at least the rear hollow partition 212 on the side close to the soil-facing side of the drawer plate has a hollow structure formed by holes 210. The above sets the frame 21 in the form of a drawer plate and a front hollow partition. After placing the filter layer in the drawer plate and inserting it into the branch channel 102, the overall installation can be completed.
[0049] In addition, it should be noted that, as Figure 1 and 3 shown, the branch channel 102 may not be connected to the main channel 101. The filter assembly 20 is arranged in the branch channel 102 to achieve the functions of draining water and preventing soil loss. However, in this structure, the ecological channel that can allow animals (especially amphibians) to pass through is only the main channel 101 and the related structures arranged therein.
[0050] Furthermore, one end of the main channel 101 close to the water-facing side and / or one end close to the soil-facing side is flared, which can induce or facilitate animals to enter the main channel 101.
[0051] Additionally, at one end of the main channel 101 close to the water-facing side and / or at one end close to the soil-facing side, there is an extension pipe inclined with respect to the central axis of the main channel 101. That is, the main channel 101 is formed in the first pipe body 1A, and at both ends of the first pipe body 1A, a second pipe body 1B and a third pipe body 1C communicating therewith are respectively provided. The second pipe body 1B on the water-facing side is vertically arranged and opens upward, and the third pipe body 1C on the soil-facing side is vertically arranged and opens downward. Such a dislocation arrangement can hinder soil movement and prevent soil erosion. Such a structure having the first pipe body 1A or both the extension pipes (the second pipe body 1B and the third pipe body 1C) is preferably used in a structure where it is not convenient to form the main channel 101 on the revetment structure. For example, when used on a sheet pile, fixing the first pipe body 1A on the sheet pile can realize the ecological channel.
[0052] Preferably, the main channel 101 has the same inner diameter and its central axis is a straight line, which is convenient for processing and forming on the revetment structure. The included angle between the central axis of the main channel 101 and the horizontal plane is α, and α ≤ 20°, which is convenient for amphibians to move inside on the inner wall of the main channel 101.
[0053] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
