Description

Technical Field

[0001] This utility model relates to the field of cofferdam structure technology, and in particular to a wetland ecological protection cofferdam structure. Background Technology

[0002] Wetland ecosystems belong to aquatic ecosystems. Their biological communities are composed of aquatic and terrestrial species. They are active in material cycling, energy flow, species migration and evolution, and have high ecological diversity, species diversity and biological productivity. Wetland ecosystems need to be protected by the use of dike structures, such as sandbag dikes, which achieve isolation by piling up sandbags.

[0003] In existing technologies, wetlands are habitats for organisms such as birds nesting and fish spawning. Traditional cofferdam construction, such as heavy equipment compaction, foundation excavation, and materials such as concrete, directly damages the wetland ecosystem, which conflicts with the core objective of wetland protection. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a wetland ecological protection cofferdam structure that has the advantages of ecological permeable channels and ecological restoration, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a wetland ecological protection cofferdam structure, including a geogrid made of plastic material, with bamboo nails A evenly fixed at the four corners of the geogrid, ecological bags evenly arranged in a linear array on the top of the geogrid, and permeable geotextile fixedly installed on the side of the ecological bags on the top of the geogrid, the permeable geotextile covering one side surface of the ecological bags, the surface of the permeable geotextile having pre-set circular holes, bamboo nails B fixedly installed on the surface of the permeable geotextile at the center of the ecological bags, and biological channels evenly arranged between the surfaces of the permeable geotextile in the gaps between the ecological bags.

[0006] Through the above structural setup, the ecological bag and the biological pipe work together to protect the ecosystem. The biological pipe is filled with a layer of pebbles and connects the water bodies on both sides. Small organisms can migrate to different areas of the wetland through the biological pipe, and the pebble layer can provide habitat for the organisms.

[0007] Preferably, the bamboo nail A and bamboo nail B consist of a nail body and a washer, wherein the washer is made of bamboo strips and is located on the surface of the geogrid and the permeable geotextile, and the nail body is made of bamboo strips.

[0008] With the above structural setup, the nail body of bamboo nail A passes through the gasket and geogrid and is inserted into the soil, while the nail body of bamboo nail B passes through the gasket and is inserted into the interior of the eco-bag, thereby achieving the fixing effect of the geogrid and the permeable geotextile respectively.

[0009] Preferably, the bottom of the ecological bag is tightly fitted to the geogrid, the interior of the ecological bag is filled with wetland native humus and native grass seeds, the ecological bags are stacked in a staggered manner on top of the geogrid, and permeable gaps are formed between the ecological bags, which are filled with a layer of gravel.

[0010] With the above structural setup, grass seeds germinate in the moist environment of wetlands in 10-15 days. The roots can penetrate the permeable holes of the ecological bag and enter the wetland soil and geogrid. The roots of the grass seeds have a dual function of soil stabilization and purification, forming an underground root network with the wetland soil and enhancing the anti-sliding stability of the cofferdam device.

[0011] Preferably, the biological pipe is a PVC pipe, which is installed in the permeable gap between the ecological bags and fits into the circular holes on the surface of the permeable geotextile. The inside of the biological pipe is filled with a layer of pebbles.

[0012] With the above-mentioned structure, the biological pipeline connects the water bodies on both sides of the cofferdam. Small organisms can migrate to different areas of the wetland through the biological pipeline, avoiding the ecological islands caused by traditional cofferdams. In addition, the pebble layer inside the biological pipeline not only prevents the channel from being blocked, but also provides habitat space for organisms.

[0013] This utility model has the following advantages:

[0014] 1. This wetland ecological protection cofferdam structure achieves ecological protection by setting up ecological bags, biological channels, and pebble layers. The biological channels are filled with pebble layers and connect the water bodies on both sides. Small organisms can migrate between different areas of the wetland through the biological channels. For example, fish and snails can crawl along the pebble layer, which provides habitat for organisms. At the same time, the gaps inside the pebble layer ensure water circulation. The grass seeds inside the ecological bags take root and extend into the wetland soil to form an underground root network, which enhances the anti-sliding stability of the cofferdam and provides habitat for birds, thus achieving the effect of ecological protection.

[0015] 2. The wetland ecological protection cofferdam structure, through the setting of ecological bags, permeable geotextile, and gravel layer, enables water circulation. Water on both sides of the cofferdam can be evenly immersed into the gravel layer and permeable geotextile through the surface of the permeable geotextile, so that the water on both sides of the cofferdam can maintain a slow exchange, avoid water hypoxia caused by the impermeability of the cofferdam, ensure the normal growth of aquatic vegetation and grass seeds, and achieve the effect of water circulation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 A wetland ecological protection cofferdam structure includes a geogrid 1 made of plastic. Bamboo nails A11 are evenly fixed at the four corners of the geogrid 1. Ecological bags 2 are evenly arranged in a linear array on the top of the geogrid 1. Permeable geotextile 3 is fixedly installed on the side of the ecological bags 2 on the top of the geogrid 1. The permeable geotextile 3 covers one side surface of the ecological bags 2. Circular holes are pre-set on the surface of the permeable geotextile 3. Bamboo nails B31 are fixedly installed on the surface of the permeable geotextile 3 at the center of the ecological bags 2. Biological channels 4 are evenly arranged between the surfaces of the permeable geotextile 3 in the gaps between the ecological bags 2.

[0022] In practical applications, this device protects the ecosystem through the cooperation between the ecological bag 2 and the biological pipe 4. The biological pipe 4 is filled with a pebble layer 41 and connects to the water bodies on both sides. Small organisms can migrate to different areas of the wetland through the biological pipe 4, and the pebble layer 41 can provide habitat for organisms. After the grass seeds inside the ecological bag 2 take root, they extend into the wetland soil to form an underground root network, which enhances the anti-sliding stability of the embankment and provides habitat for birds.

[0023] Through the cooperation between the ecological bag 2 and the gravel layer 5, the water on both sides of the cofferdam can be permeable without being blocked. The water on both sides of the cofferdam can slowly exchange with the gravel layer 5 through the permeable geotextile 3, which can ensure the amount of oxygen permeable while maintaining the normal growth of aquatic plants such as grass seeds.

[0024] Please see Figures 1-2Bamboo nails A11 and B31 consist of a nail body and a washer. The washer is made of bamboo strips and is located on the surface of the geogrid 1 and the permeable geotextile 3. The nail body is made of bamboo strips. The nail body of bamboo nail A11 passes through the washer and the geogrid 1 and is inserted into the soil. The nail body of bamboo nail B31 passes through the washer and is inserted into the interior of the ecological bag 2, thereby achieving the fixing effect of the geogrid 1 and the permeable geotextile 3 respectively.

[0025] The permeable geotextile 3 is fixed to one side of the surface of the eco-bag 2 with bamboo nails B31, but due to the material of the permeable geotextile 3, it will not hinder the exchange of water flow.

[0026] Due to the natural biodegradability of bamboo, and the sufficient strength of bamboo to meet the fixing requirements of geogrid 1 and permeable geotextile 3, bamboo nails A11 and B31 achieve short-term fixation and long-term residue-free operation. After a period of time, the bamboo will naturally decompose in the wetland environment and become organic matter in the soil, eliminating the need for manual removal.

[0027] Please see Figures 1-3 The bottom of the ecological bag 2 is tightly fitted to the geogrid 1. The interior of the ecological bag 2 is filled with wetland native humus and native grass seeds. Depending on the actual situation, the grass seeds can be reeds or calamus. The ecological bags 2 are stacked in a staggered manner on top of the geogrid 1, and permeable gaps are formed between the ecological bags 2. The permeable gaps between the ecological bags 2 are filled with a layer of gravel 5.

[0028] After stacking the ecological bags 2, spray a small amount of water onto the surface of the ecological bags 2 as needed. The grass seeds will germinate in the moist environment of the wetland in 10-15 days. The roots can penetrate the permeable holes of the ecological bags and enter the wetland soil and geogrid 1. The roots of the grass seeds have a dual function of soil stabilization and purification, forming an underground root network with the wetland soil, which enhances the anti-sliding stability of the cofferdam device. At the same time, the above-ground part of the vegetation covers the surface of the cofferdam, providing a habitat for birds.

[0029] Please see Figures 1-3 The biological pipe 4 is a PVC pipe. The biological pipe 4 is set in the permeable gap between the ecological bags 2 and fits into the circular holes on the surface of the permeable geotextile 3. The biological pipe 4 is filled with a pebble layer 41, which forms a foothold for aquatic organisms. For example, fish and snails can crawl along the pebble layer 41. At the same time, the gaps inside the pebble layer 41 ensure water circulation.

[0030] The biological pipe 4 connects the water bodies on both sides of the cofferdam at both ends. Small organisms can migrate to different areas of the wetland through the biological pipe 4, avoiding the ecological islands caused by traditional cofferdams. In addition, the pebble layer 41 inside the biological pipe 4 not only prevents the passage from being blocked, but also provides habitat space for organisms, improving the passage rate of organisms.

[0031] The permeable gaps between the ecological bags 2 are filled with a layer of gravel 5, which forms a permeable channel in the permeable gaps. Water can slowly exchange and circulate through the gaps inside the gravel layer 5, while the mud and sand in the water are filtered out of the gaps by the pebble layer 41 to avoid clogging.

[0032] Working principle: When using it, first lay the geogrid 1 flat on the wetland surface, then fold the four corners of the geogrid 1, place the bamboo nail A11 bamboo pad at the fold, and then insert the bamboo nail A11 nail body into the wetland soil to fix the position of the geogrid 1.

[0033] Then, the ecological bags 2 filled with humus and grass seeds are stacked in a staggered manner along the surface of the geogrid 1 to form a water-permeable gap between the ecological bags 2. The bottom of the ecological bags 2 is tightly attached to the geogrid 1, but the geogrid 1 does not obstruct the water permeability of the ecological bags 2. Then, the biological pipes 4 filled with the pebble layer 41 are placed in the water-permeable gap of the ecological bags 2, and then the outer ring of the biological pipes 4 is filled with the gravel layer 5 so that the gravel layer 5 fills the gap between the biological pipes 4 and the ecological bags 2.

[0034] Then, evenly cover one side of the surface of the ecological bag 2 with the permeable geotextile 3, align the circular holes of the permeable geotextile 3 with the biological pipe 4 and fit it around the outer ring of the end of the biological pipe 4. Use bamboo nails B31 to fix the permeable geotextile 3 to the ecological bag 2, so as to achieve the effect of fixing the biological pipe 4 and the gravel layer 5 without hindering water exchange.

[0035] In subsequent use, small organisms can crawl and swim through the biological pipes 4 to migrate to different areas of the wetland, avoiding the formation of ecological islands. The pebble layer 41 can prevent blockage while providing habitat for organisms.

[0036] Water on both sides of the cofferdam can be evenly absorbed into the gravel layer 5 and the permeable geotextile 3 through the surface of the permeable geotextile 3, so that the water on both sides of the cofferdam can maintain a slow exchange, avoid water hypoxia caused by the impermeability of the cofferdam, ensure the normal growth of aquatic vegetation and grass seeds, and after the grass seeds take root, the root system connects with the wetland soil to form an underground root network, which can enhance the anti-sliding stability of the cofferdam.
