Description
Technical Field
[0001] This utility model relates to the field of ecological protection and restoration technology, and in particular to a biological passage facility for protecting organisms in construction areas. Background Technology
[0002] Facilities that allow organisms to safely pass beneath human-constructed areas refer to pathways connecting major habitat patches, facilitating the flow of genes, energy, and matter. Biotransfer facilities play a crucial role in protecting wildlife and the ecological environment. They prevent population isolation, maintain minimum population sizes, and protect biodiversity, helping to reduce or even eliminate the impacts of habitat fragmentation on biodiversity. These facilities are typically used to ensure that specific species can move freely within large areas, and to ensure that species with seasonal migration habits can travel between breeding and wintering grounds throughout the year, maintaining their original migration routes undisturbed by human activities. They are of great significance for protecting biodiversity and maintaining ecological balance, providing wildlife with safe passage through areas of human activity and reducing harm to animals from traffic accidents.
[0003] To date, research has mainly focused on water conservancy structures such as canals, rivers, and dikes. However, when wild organisms face human-caused environmental disturbances such as roads, they can alter the habitats, breeding grounds, and migration routes of some wild plants and animals, causing habitat fragmentation and isolation, and even creating spatial barriers to gene exchange between individuals, threatening their survival and reproduction, and potentially exacerbating the decline or even extinction of rare and endangered species.
[0004] Therefore, there is a need to provide a biological corridor facility to protect the passage of organisms in the construction area, to build safe habitat corridors for wild animals such as reptiles, arthropods, and mammals, to increase the suitability of various organisms, effectively ensure the safe passage of wild animals, and reduce human interference. Utility Model Content
[0005] The technical problem to be solved by this utility model is: to provide a biological passage facility for protecting organisms in construction areas, in view of the above-mentioned problems.
[0006] The technical solution adopted in this utility model is: a biological passage facility for protecting organisms in a construction area, comprising:
[0007] The biological passage unit is located below the construction area and has a hollow passage inside to facilitate the passage of organisms.
[0008] Through holes, located at the top of the biological channel unit, are arranged in an array to facilitate the penetration of external light into the channel;
[0009] Connectors, located at both ends of the biological channel unit, are used to sequentially splice adjacent biological channel units so that the length of the formed channel corresponds to the extension distance of the construction area.
[0010] By employing the aforementioned technical methods and setting up hollow bio-channel units beneath human-built areas, a relatively safe passage environment can be provided for different species, reducing the risk of direct exposure to the ground and human interference such as traffic. The array-like distribution of the perforations allows external light to penetrate the channel, increasing its brightness and alleviating the fear animals experience when traversing in darkness. Multiple bio-channel units can be spliced together using connectors, allowing for flexible adjustment of channel lengths to adapt to varying distances within urban development areas, ensuring sufficiently wide channel coverage and effectively connecting scattered habitat patches.
[0011] In some embodiments, the biological channel unit adopts a gate-shaped structure with a cross-section that is round at the top and square at the bottom. The top arch and the inner bottom of the biological channel unit are both planar, and the top arch of the biological channel unit is provided with a plurality of through holes.
[0012] In some embodiments, the bottom of the biological channel unit is provided with a soil layer, and plants are placed in the soil layer. Moisture-tolerant or drought-tolerant plants are selected according to the regional climate, and the thickness of the soil layer is not less than 10 cm.
[0013] In some embodiments, the surface of the soil layer is covered with a layer of leaf mold, and decomposer organisms capable of accelerating the decomposition of organic matter are introduced.
[0014] In some embodiments, the bottom of the soil layer is provided with a permeable geotextile and a gravel layer to form a permeable composite structure of "soil layer-permeable geotextile-gravel layer".
[0015] In some embodiments, the connector includes a first embedded buckle and a second embedded buckle. A pair of first embedded buckles are symmetrically provided at the bottom of one end of the biological channel unit, and a pair of second embedded buckles are symmetrically provided at the bottom of the other end of the biological channel unit. Adjacent biological channel units are spliced together by the snap-fit between the first embedded buckle and the second embedded buckle.
[0016] In some embodiments, the sidewall of the first embedded buckle is provided with a vertically arranged snap-fit groove, and the second embedded buckle is provided with a vertically arranged snap-fit protrusion, and the snap-fit groove and the snap-fit protrusion can be inserted and engaged.
[0017] In some embodiments, the biological channel unit is constructed using C30 concrete.
[0018] Another technical solution adopted by this utility model is: a method for using a biological passage facility to protect organisms in a construction area, comprising the following steps:
[0019] S1. Excavation of the foundation pit: Excavation is carried out in a section of the highway to form a foundation pit that meets the installation requirements of the biological passage unit;
[0020] S2. Foundation laying: Lay a layer of crushed stone and a layer of soil at the bottom of the foundation pit as a foundation.
[0021] S3. Set up positioning marks. After the foundation is laid at the bottom of the pit, set up positioning marks by setting benchmark points, pulling lines for positioning, and marking the installation position to assist in the subsequent hoisting of biological tunnel units.
[0022] S4. The first biological channel unit is hoisted and placed to the preset position using a lifting device with the assistance of a marker.
[0023] S5. The biological channel units are placed continuously, and the subsequent units are placed in sequence using lifting equipment until the construction of the entire biological channel is completed.
[0024] S6. Remove positioning markers: Remove all markers used for positioning.
[0025] S7. Backfilling the remaining area of the foundation pit: Backfill the foundation pit according to the original road material type and layer sequence.
[0026] S8. Road surface leveling treatment: The road surface is leveled to ensure that the top of the biological passage is level with the surrounding road surface.
[0027] In some embodiments, the installation requirements for the biological passage unit in step S1 include: the length of the pit is the width of the road, the width of the pit is greater than the preset width of the biological passage unit, the extra width should ensure sufficient operating space during installation, and the depth of the pit is determined based on the gravel layer, the soil layer and the total height of the biological passage unit.
[0028] In some embodiments, in step S3, setting the reference points involves setting fixed reference points at both ends and the middle of the pit, and marking the reference points with reference point spikes; the string positioning involves connecting the reference point spikes with nylon rope or steel strand to form an installation reference line for the biological passage unit; and marking the installation position involves using reflective tape to mark the installation position of each biological passage unit along the installation reference line.
[0029] In some embodiments, step S5, the step of using lifting equipment to continue hoisting and placing subsequent units in sequence, includes: when hoisting and placing subsequent biological channel units, the lowering position of the biological channel units should be controlled with the assistance of positioning markers, and it should be ensured that adjacent biological channel units are tightly connected through bottom connectors.
[0030] The beneficial effects of this utility model are:
[0031] 1. By setting up bio-channel units beneath the construction area, the hollow passageways within these units provide a relatively safe passage environment for wildlife, reducing wildlife casualties caused by traffic accidents and lowering the risk of roadkill. The array of perforations at the top of the bio-channel units allows external light to penetrate, ensuring adequate lighting conditions. Good lighting aids wildlife navigation and activity, reducing their fear when traversing in darkness. Multiple bio-channel units can be connected using connectors, allowing for flexible adjustment of channel lengths to accommodate construction areas of varying distances. This ensures sufficiently wide channel coverage, effectively connecting scattered habitat patches, reducing the negative impacts of habitat fragmentation, and maintaining or even increasing biodiversity within the area.

[0038] This specification includes references to "one embodiment" or "implementation". The use of the phrase "in one embodiment" or "in an embodiment" does not necessarily refer to the same embodiment. Specific features, structures, or characteristics may be combined in any suitable manner consistent with this disclosure.
[0039] The term "comprising" is open-ended. As used in the appended claims, it does not exclude additional structures or steps.
[0040] "First," "second," etc. As used in this article, these terms serve as labels for the nouns preceding them and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.). Detailed Implementation
[0041] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.
[0042] Example 1:
[0043] Combination Figures 1 to 4 As shown, this embodiment is a biological passage facility for protecting organisms in a construction area, including a biological passage unit 1, through holes 2, and connectors 3. The biological passage unit 1 is located below the construction area, and its interior has a hollow channel to facilitate organism passage. Multiple through holes 2 are arranged in an array at the top of the biological passage unit 1 to allow light to penetrate the channel. Connectors 3 are located at both ends of the biological passage unit 1, and are used to sequentially connect adjacent biological passage units 1 so that the length of the channel formed by the multiple biological passage units 1 corresponds to the extension distance of the construction area.
[0044] In some implementation schemes, such as Figure 1 and Figure 3 As shown, in this embodiment, the biological passage unit 1 adopts a gate-shaped structure with a cross-section that is round at the top and square at the bottom. The top arch and the inner bottom of the biological passage unit 1 are both planar. In this embodiment, the height and width of the biological passage unit 1 are 0.5m. The specific dimensions are adaptively adjusted according to the size and habits of the animals in the vicinity of the area to flexibly meet the needs of different species.
[0045] The top arch of the biological passage unit 1 is perforated with multiple arrayed through-holes 2. In this embodiment, the diameter of the through-holes 2 is 2–5 cm. This size range can filter out most large debris (such as stones) while still allowing smaller particles (such as dust and fallen leaves) or rainwater to enter, thus harmonizing the internal area of the passage with the external environment. The specific size of the through-holes is adjusted according to the size and habits of the animals in the vicinity. The size range of the through-holes covers the activity needs of small arthropods while preventing large animals from getting trapped, thus taking into account the adaptability of multiple species. For example, the through-holes can be reduced in areas dominated by reptiles, while the passage cross-section can be increased in mammal migration routes, demonstrating a high degree of targeting.
[0046] By adopting a gate-like structure with a round top and square bottom, not only is an aesthetically pleasing design ensured, but it also provides excellent load-bearing capacity, contributing to the overall stability of the biological passage unit 1. This shape also provides more spacious room for organisms to pass through, which is especially important for larger mammals.
[0047] Furthermore, the bottom of the biological passage unit 1 is provided with a soil layer, within which plants are placed. The plants are selected based on the local climate, choosing either moisture-tolerant or drought-tolerant varieties to enhance the soil's water retention and drainage capacity. The soil layer and the covering medium (plants, etc.) are at least 10cm thick to ensure normal plant growth. In this embodiment, moss is used, but more complex ecological structures can also be employed to meet the needs of different organisms. The surface of the soil layer is covered with a layer of leaf mold, and decomposers are introduced into the soil layer to accelerate the decomposition of organic matter and maintain the internal ecological cycle. Specifically, in this embodiment, the decomposers include earthworms and microorganisms. The bottom of the soil layer is provided with a permeable geotextile and a gravel layer to form a permeable composite structure of "soil layer - permeable geotextile - gravel layer," thereby increasing the permeability of the passage bottom.
[0048] The soil and plant environment within Biochannel Unit 1 can provide food and habitat for animals, increasing their living space and alleviating survival pressures. By increasing vegetation and creating connected green spaces, the mobility of plants and animals is enhanced, thus increasing the ecological function of Biochannel Unit 1.
[0049] On the one hand, the multiple openings on the arch allow for increased natural light penetration, ensuring adequate lighting conditions within the passageway. Natural light aids wildlife in navigation and behavioral activities, such as finding food and avoiding predators. Simultaneously, good lighting helps them identify the passageway entrance and internal structure, reducing their fear and hesitation about the darker areas, thus increasing passageway utilization. On the other hand, good light transmission promotes the growth and health of plants within the passageway. The soil layer and the moss planted within it provide habitats for small organisms and enhance the realism and comfort of the passageway, attracting diverse species to use it. Furthermore, sufficient light facilitates maintenance personnel's inspection of the passageway, enabling them to perform necessary maintenance and monitoring.
[0050] Furthermore, the biological channel unit 1 is constructed using C30 concrete.
[0051] The use of C30 grade concrete for pouring means that the biological passage unit 1 has high strength and durability, and can withstand certain external pressures, including vibrations from the soil above or vehicles, ensuring safety for long-term use.
[0052] In some implementations, the connector 3 includes a first embedded buckle and a second embedded buckle. A pair of first embedded buckles are symmetrically provided at the bottom of one end of the biological channel unit 1, and a pair of second embedded buckles are symmetrically provided at the bottom of the other end of the biological channel unit 1. Adjacent biological channel units 1 are spliced together by the snap-fit between the first embedded buckle and the second embedded buckle.
[0053] Furthermore, the side wall of the first embedded buckle is provided with a vertically arranged snap-fit groove, and the second embedded buckle is provided with a vertically arranged snap-fit protrusion, and the snap-fit groove and the snap-fit protrusion can be inserted and engaged.
[0054] The design of the first and second embedded buckles facilitates the splicing of adjacent biological channel units 1, simplifying construction while ensuring a secure connection. The interlocking fit between the snap-fit groove and the snap-fit protrusion reduces construction difficulty and improves efficiency, while also facilitating disassembly and maintenance.
[0055] like Figure 4 As shown in the figure, this embodiment illustrates a structure in which three biological channel units 1 are spliced together. Multiple modules can be formed through splicing, and the modular design makes the construction and maintenance of the channels more flexible, facilitating adjustments according to actual needs. The modular design allows the biological channel units 1 to be prefabricated in the factory and then assembled on-site, reducing the complexity and time required for on-site construction.
[0056] The implementation principle of a bio-channel facility for protecting organisms in a construction area is as follows:
[0057] By setting up biochannel units 1 below the construction area, the hollow channels within biochannel units 1 provide a relatively safe passage environment for different species. The array of through-holes 2 at the top of the biochannel arch allows external light to penetrate, increasing brightness and reducing animal fear in darkness. This may also promote the growth of certain light-demanding plants, thus enriching the ecosystem within the channel. Depending on the actual construction area's extension, multiple biochannel units 1 are spliced together using first and second embedded clips, effectively connecting scattered habitat patches. This biochannel facility helps reduce the negative impacts of habitat fragmentation, maintaining and even increasing biodiversity within the area. By providing physically continuous pathways, it promotes gene exchange between species, contributing to the health and stability of the ecosystem. Simultaneously, it reduces the likelihood of animals crossing roads and other man-made structures, lowering the resulting traffic accident rate.
[0058] Example 2:
[0059] This embodiment describes a method for using a bio-channel facility to protect organisms in a construction area, applied to the bio-channel facility in Embodiment 1, and includes the following steps:
[0060] S1. Excavation of the foundation pit: Excavation is carried out in a section of the highway to form a foundation pit that meets the installation requirements of biological passage unit 1.
[0061] S1.1 Before burying the biological passage, partial excavation of the existing highway should be carried out to form the biological passage foundation pit. The installation requirements for biological passage unit 1 include: the length of the foundation pit should completely extend through the width of the highway to meet the needs of biological migration and ecological protection; the width of the foundation pit should be greater than the preset width of biological passage unit 1, and the extra width should ensure sufficient operating space during installation; the depth of the foundation pit should be determined based on the gravel layer, soil layer and the total height of biological passage unit 1, and should ensure that all biological passage units 1 can reach the design required burial depth during installation, so that the top surface of biological passage unit 1 is flush with the original highway surface after installation.
[0062] S2. Foundation laying: Lay a layer of crushed stone and a layer of soil at the bottom of the foundation pit as a foundation.
[0063] S2.1 After the excavation of the foundation pit is completed, a layer of crushed stone should be laid at the bottom of the foundation pit, and then covered with a soil layer to serve as the base of biological passage unit 1.
[0064] S3. Set up positioning marks. After the foundation is laid at the bottom of the pit, set up positioning marks by setting benchmark points, pulling lines for positioning, and marking the installation position to assist in the subsequent hoisting and placement of biological tunnel unit 1.
[0065] S3.1 Setting reference points involves setting fixed reference points at both ends and the middle of the pit, and marking the reference points with reference point spikes; stringing positioning involves using high-strength nylon rope or steel strand to connect the reference point spikes to form the installation reference line for biological channel unit 1; marking installation positions involves using reflective tape or other obvious markings to indicate the installation position of each biological channel unit 1 along the installation reference line.
[0066] S4. The first biological channel unit 1 is hoisted and placed to the preset position using a lifting device with the assistance of a marker.
[0067] S4.1. Using a lifting device and with the aid of a marker, accurately lift the first unit to the center of one end of the foundation pit, where the position of the axis coincides with the position of the central axis of the foundation pit.
[0068] S5. Biochannel unit 1 is placed continuously, and subsequent units are placed in sequence using lifting equipment until the entire biochannel is constructed.
[0069] S5.1 After the first biological channel unit 1 is hoisted and placed, subsequent biological channel units 1 are hoisted and placed accurately to the positions immediately adjacent to the previous unit using lifting equipment. This process is repeated until all units are placed according to the design requirements, forming a continuous and stable biological channel structure. It should be noted that when hoisting subsequent biological channel units 1, the lowering position of the biological channel unit 1 should be controlled with the assistance of positioning markers, and it should be ensured that adjacent biological channel units 1 are tightly connected via the bottom connector 3, i.e., by using the first and second embedded buckles for locking and engaging, ultimately forming a stable and connected overall structure.
[0070] S6. Remove positioning markers: Remove all markers used for positioning.
[0071] S6.1 After all biological channel units 1 are installed, the baseline should be removed, the baseline spikes and other baseline markers should be removed, and the foundation pit at the location where the baseline markers are set should be leveled.
[0072] S7. Backfill the remaining area of the foundation pit. Backfill the foundation pit according to the original road material type and layer order.
[0073] S7.1 After the removal of the positioning markers, the remaining area in the foundation pit, excluding the space occupied by biological passage unit 1, should be backfilled according to the original road construction material type and layer order to ensure the integrity and stability of the road.
[0074] S8. Road surface leveling treatment: The road surface is leveled to ensure that the top of the biological passage is level with the surrounding road surface, so as to ensure driving safety and the functionality of the biological passage.
[0075] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
