Abstract
Description
Technical Field
[0001] The utility model belongs to the field of water conservancy projects, and more specifically, relates to a structure for enhancing the hydrodynamic force of a shoal wetland. Background Art
[0002] Considering that most of the regional backbone rivers are waterways and undertake the task of regional flood-season drainage, shoal wetlands are mostly arranged on the concave banks of the river channels in the lake and pond sections. The wetland is located far from the main stream, and the water flow is mostly the internal return flow in the region under the squeezing action of the main stream. The water body exchange is poor, and nutrient enrichment is likely to occur, resulting in the overgrowth of aquatic plants, high treatment costs, and difficult management; moreover, the purification effect of the wetland itself has not been effectively exerted, and measures need to be taken to enhance the hydrodynamic force of the shoal wetland. Currently, the conventional measures mainly include: building new sluices, pumping stations and other inlet control buildings, which are costly and have poor ecological effects. Content of the Utility Model
[0003] The purpose of the utility model is to provide a structure for enhancing the hydrodynamic force of a shoal wetland in view of the deficiencies of the existing technology. Without adding too much economic cost to build sluices and pumping stations, this structure can enhance the dynamic conditions of the water flow from the main river channel to the shoal wetland.
[0004] To achieve the above purpose, the utility model provides a structure for enhancing the hydrodynamic force of a shoal wetland, including:
[0005] A diversion dike is arranged between the main river channel and the shoal wetland, and the diversion dike is in a Y shape;
[0006] A dike is arranged between the main river channel and the shoal wetland. The diversion dike is arranged at the water inlet of the dike. The water flow of the main river channel is diverted by the diversion dike and flows through both sides of the shoal wetland, and finally converges at the water outlet of the dike and returns to the main river channel.
[0007] Optionally, the dike includes imitation wooden piles on both sides and soil filled between the piles. Aquatic plants are planted on the shoal wetland between the diversion dike and the revetment.
[0008] Optionally, metasequoia is planted on the imitation wooden piles.
[0009] Optionally, the imitation wooden piles are located on the side of the dike close to the main river channel.
[0010] Optionally, the height of the imitation wooden piles is not lower than the height of the shoal wetland.

[0012] Optionally, a sluice or a lift pump station is also provided in the mainstream river channel.
[0013] The utility model provides a structure for enhancing the hydrodynamic force of a shoal wetland, and its beneficial effects are as follows: in this structure, the diversion dike is arranged in a Y shape to adjust the flow pattern of the water flowing from the mainstream river channel to the shoal wetland, so as to enhance the hydrodynamic conditions of the wetland.

[0020] The following will describe the preferred embodiments of the utility model in more detail. Although the following describes the preferred embodiments of the utility model, it should be understood that the utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the utility model more thorough and complete, and to convey the scope of the utility model fully to those skilled in the art.
[0021] The utility model provides a structure for enhancing the hydrodynamic force of a shoal wetland, comprising:
[0022] A diversion dike is arranged between the mainstream river channel and the shoal wetland, and the diversion dike is in a Y shape;
[0023] The dividing dike is set between the main river channel and the shallow wetland. The diversion dike is set at the water inlet of the dividing dike. The water flow of the main river channel is diverted through the diversion dike and flows past both sides of the shallow wetland, and finally converges at the water outlet of the dividing dike and returns to the main river channel.
[0024] Specifically, this structure is set between the main river channel and the shallow wetland. Among them, the main river channel and the shallow wetland are separated by the dividing dike. In this way, a part of the water flow of the main river channel can flow through the area between the dividing dike and the revetment. Since the diversion dike is set on the dividing dike, the water entering this area is diverted to pass through both sides of the shallow wetland, and finally converges into the main river channel. In this way, the adjustment of the flow regime can be realized, and the effect of improving the hydrodynamic conditions of the wetland can be achieved.
[0025] Optionally, the dividing dike includes imitation wooden piles on both sides plus filled soil between the piles. Aquatic plants are planted on the shallow wetland between the diversion dike and the revetment.
[0026] Optionally, the imitation wooden piles are located on the side of the dividing dike close to the main river channel.
[0027] Specifically, the outer edge of the dividing dike is fixed with imitation wooden piles, which can reduce the erosion of the water flow in the bend section. Planting aquatic plants between the dividing dike and the foreshore wetland can conserve water sources and form a space for biological habitats.
[0028] Optionally, metasequoia is planted on the imitation wooden piles.
[0029] Specifically, metasequoia is planted on the imitation wooden piles. In this way, there is metasequoia not only on the dividing dike, but also on the shallow wetland. And aquatic plants are planted between the dividing dike and the revetment. In this way, the wetland is coordinated with the surrounding area, not only purifying the water source, but also providing a living space for animals and plants.
[0030] Optionally, the height of the imitation wooden piles is not lower than the height of the shallow wetland.
[0031] Specifically, the imitation wooden piles, as the bottom support of the dividing dike, can separate the main river channel and the tributary river channel, and divert the water flow entering the tributary river channel and improve the hydrodynamic force, so that the river water can flow in the tributary river channel formed between the dividing dike and the shallow wetland, which can change the water flow structure.
[0032] Optionally, the shallow wetland is set between the dividing dike and the revetment. A first tributary river channel is formed between the dividing dike and the shallow wetland, and a second tributary river channel is formed between the shallow wetland and the revetment.
[0033] Specifically, when there is water flow in the mainstream river channel passing through the diversion dike, due to the shape of the diversion dike, the water flow can be divided into two paths, flowing along the first tributary river channel and the second tributary river channel respectively. Then, when between the two shallow wetland areas of the flow channel, part of the water flow in the second tributary river channel will converge with the water flow in the first tributary river channel along the first shallow wetland area and continue to flow along the river channel between the dike and the second shallow wetland area. In this way, the original water flow structure of the second tributary river channel changes again. There is also a part of the water flow in the second tributary river channel that will continue to flow along the river channel between the second shallow wetland area and the bank protection, but ultimately it will still converge at the water outlet of the dike and return to the mainstream river channel again. Similarly, the water flow structure changes during the flowing process. In this way, the hydrodynamic force of the wetland can be enhanced through this structure.
[0034] Optionally, a sluice or a pumping station is also provided in the mainstream river channel.
[0035] Specifically, this structure can be compatible with the forms of the sluice and the pumping station provided on the mainstream river channel. Just this structure can also achieve the enhancement of the hydrodynamic force without adding too much economic cost, and can purify the water source and provide more living space for the surrounding animals and plants.
[0036] Embodiment
[0037] As Figures 1 to 2 shown, the present utility model provides a structure for enhancing the hydrodynamic force of a shallow wetland, including:
[0038] A diversion dike 4, which is arranged between the mainstream river channel 1 and the shallow wetland 2, and the diversion dike 4 is in a Y shape;
[0039] A dike 10, which is arranged between the mainstream river channel 1 and the shallow wetland 2, and the diversion dike 4 is arranged at the water inlet of the dike 10. The water flow in the mainstream river channel 1 is diverted by the diversion dike 4 and flows through both sides of the shallow wetland 2, and finally converges at the water outlet of the dike 10 and returns to the mainstream river channel 1.
[0040] In this embodiment, the dike 10 includes imitation wooden piles 5, and aquatic plants 6 are planted between the imitation wooden piles 5 and the shallow wetland 2.
[0041] In this embodiment, metasequoia glyptostroboides 7 is planted on the imitation wooden piles 5.
[0042] In this embodiment, the imitation wooden piles 5 are located on the side of the dike 10 close to the mainstream river channel 1.
[0043] In this embodiment, the height of the imitation wooden piles 5 is not lower than the height of the shallow wetland 2.
[0044] In this embodiment, the shoal wetland 2 is arranged between the dike 10 and the revetment 3. A first branch channel 8 is formed between the dike 10 and the shoal wetland 2, and a second branch channel 9 is formed between the shoal wetland 2 and the revetment 3.
[0045] In this embodiment, a sluice or a lift pump station is also arranged in the main channel 1.
[0046] In summary, without the need to build a sluice and a lift pump station on the main channel 1, the flow structure entering the shoal wetland 2 is adjusted through the Y-shaped diversion dike 4 to achieve the improvement of the wetland hydrodynamic force. Moreover, imitation wooden piles 5 are arranged in the front row of the dike 10, which can slow down the impact of the water flow on the diversion dike 4. Aquatic plants 6 and metasequoia 7 are planted on the imitation wooden piles 5 and the shoal wetland 2, making the structure more coordinated with the overall wetland. It is also beneficial to purify the water source and provide more living space for animals and plants. In addition, through the construction of the diversion dike 4, the water flow during project water diversion is used to avoid nutrient enrichment. At the same time, an urban landscape wetland park can be built in combination to beautify the urban ecological environment.
[0047] The embodiments of the present invention have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
