Abstract
Description
Technical Field
[0001] The utility model relates to an ecological corridor, especially an ecological corridor which is modularly designed, has height adjustability, mobility, maintenance flexibility and revisability, has a relatively low overall preparation cost, a fast erection speed, convenient maintenance, and can provide various biological species for upstream and migration use. Background Art
[0002] Due to the limited fresh water resources on the island, and most of them are intercepted by lakes and reservoirs. For the consideration of regulation and irrigation, water retaining weirs are densely built in some streams, ditches and drainage ditches. Since the engineering forms of these water retaining weirs are the same as those of the sand prevention dams, which are transverse structures, the water retaining weirs and sand prevention dams cannot effectively achieve the functions of water storage and sediment discharge. In a short time, the water depth becomes shallow due to siltation, and the water temperature is easily affected by the air temperature. As a result, fish die in large numbers due to the water temperature change during the winter cold snap due to the lack of a deep water environment, or the fish cannot survive due to lack of oxygen in the water caused by the dense aquatic plants covering the water surface in summer. At the same time, the ecological habitat also needs to be dredged frequently by machinery due to degradation, so the interference to the stream ecology is quite serious and there is a waste of public funds.
[0003] Inspecting the transverse structures set in lakes, reservoirs and streams, they will all cause obstacles to the longitudinal passage of organisms. It is not easy for aquatic organisms to migrate from lakes and reservoirs into streams. Therefore, the biological resources are less and less upstream. Since the regulation of past rivers and drainage ditches did not consider the biological corridor problem of migratory organisms, the overflow weir has become the biggest artificial obstacle. There is no effective biological corridor for upstream fish to use. Moreover, due to excessive cementation, overly steep rigid structure revetments and the drop of transverse structures, it is also an obstacle for aquatic organisms (turtles and small mammals) to move directly longitudinally, resulting in climbing onto the land and detouring to find suitable habitats or waters, and then these organisms straying into the roads beside the waters and being at risk of being killed on the road. In addition, these artificial transverse structures such as overflow weirs, water retaining weirs, bed protection works, sand retaining dams, etc. will cause the interruption of the communication between water systems, the cutting of fish habitats and the inability of aquatic biological resources to be interconnected, and then will damage the ecology and even cause ecological catastrophes and species extinctions. Content of the Utility Model
[0004] The main technical problem to be solved by the utility model is to overcome the above-mentioned defects existing in the prior art, and provide an ecological corridor which is modularly designed, has height adjustability, mobility, maintenance flexibility and revisability, has a relatively low overall preparation cost, a fast erection speed, convenient maintenance, and can provide various biological species for upstream and migration use, reducing ecological damage and species extinction.
[0005] The technical solution adopted by the utility model to solve its technical problems is:
[0006] An ecological corridor has a corridor body. On both sides of the corridor body, water-stop walls are respectively extended. A passage space is formed between the two water-stop walls. On one side of the passage space of the corridor body, several arc-shaped grooves are arranged along the water-stop wall. On the other side of the passage space opposite to the arc-shaped grooves, several conical channels are arranged obliquely, so that these conical channels form a staircase in the passage space, and the height and cross-sectional area of the conical channels converge and gradually shrink from the inner side of the passage space to the outer end near the water-stop wall, so that the conical channels form an inclined shape.
[0007] The beneficial effects of the present utility model are that through modular design, it has height adjustability, mobility, maintenance flexibility and modifiability, and the overall preparation cost is low, the erection speed is fast, the maintenance is convenient, and it can provide a variety of biological species for upstream and migration use, reducing ecological damage and biological extinction.

[0021] Regarding the technical means and structure used by the present utility model to achieve the purpose, it is hereby further described in detail in conjunction with Figures 1 to 5 the embodiments shown as follows:
[0022] As shown in Figure 1 、2 As shown in FIGS. 3, the ecological corridor of the present utility model has a corridor body 10. On both sides of the corridor body 10, water-stop walls 11 are respectively extended. A passage space 12 is formed between the two water-stop walls 11. On one side of the passage space 12 of the corridor body 10, several arc-shaped grooves 13 are arranged along the water-stop walls 11. On the other side of the passage space 12 opposite to the arc-shaped grooves 13, several conical channels 14 are arranged obliquely, so that the conical channels 14 form a staircase in the passage space 12, and the height and cross-sectional area of the conical channels 14 converge and gradually shrink from the inner side of the passage space 12 to the outer end near the water-stop walls 11, so that the conical channels 14 form an inclined shape.
[0023] As mentioned above, coupling members (not shown in the figures) are respectively provided at the upper and lower ends of the corridor body 10. The coupling members (not shown in the figures) can be used to serially connect two corridor bodies 10. When the coupling members (not shown in the figures) are positioning pin holes, after two corridor bodies 10 are serially connected, personnel can insert positioning pins into the positioning pin holes, and then the two corridor bodies 10 can be serially connected and combined, so that the corridor bodies 10 will not separate and fall off.
[0024] With the above structure, according to the ecological types of different water retaining weirs and overflow weirs, and according to the size and height of the hinterlands of the water retaining weirs and overflow weirs, the corridor body 10 can be used alone or several corridor bodies 10 can be serially connected and combined (as shown in Figure 4 ), and then the upper part of the corridor body 10 is arranged on engineering structures 20 such as water retaining weirs and overflow weirs (as shown in Figure 5 ), and the lower part of the corridor body 10 is placed in streams, lakes and reservoirs, and then an inclined ecological corridor can be formed by combination.
[0025] Then, because the ecological corridor is arranged at engineering structures 20 such as water retaining weirs and overflow weirs, the water flow on the engineering structures 20 such as water retaining weirs and overflow weirs can flow down through the corridor body 10 (as shown in Figure 5As shown, while taking advantage of the blocking effect of the water-stop walls 11 provided on both sides of the corridor body 10, the water flowing through the passage space 12 has a concentrated confluence effect; in particular, since the conical channels 14 on the corridor body 10 are arranged in a ladder shape, and the conical channels 14 converge and taper from the inside to the outside, different flow velocities will be generated when the liquid flows through the conical channels 14. Regarding the end of the conical channel 14 close to the water-stop wall 11, since the cross-sectional area of the end of the conical channel 14 close to the water-stop wall 11 is smaller, the height obstacle formed is less affected, so the flow velocity of the liquid here will be faster and it is not easy to accumulate liquid; regarding the front end of the conical channel 14 close to the center of the passage space 12, since the cross-sectional area of the front end of the conical channel 14 close to the center is larger, a height obstacle will be formed, so that the flow velocity of the liquid will decrease and slow down when flowing through here, and the liquid is blocked by the conical channel 14, so that liquid will accumulate here to produce deep water accumulation.
[0026] Regarding amphibious organisms (such as turtles and soft-shelled turtles) or other mammalian organisms in streams, lakes and reservoirs, they can crawl through the passage space 12 provided on the corridor body 10. And because the corridor body 10 is provided with several arc-shaped grooves 13, due to the design of the passage space 12 having both a plane and arc-shaped grooves 13 at the same time, amphibious organisms (such as turtles and soft-shelled turtles) or other mammalian organisms have support when crawling, so the difficulty of their movement can be reduced, enabling the amphibious organisms and mammalian organisms to crawl up (or down) smoothly.
[0027] Regarding aquatic organisms (such as fish, shrimps, crabs, etc.), the corridor body 10 is provided with conical channels 14, and due to the height and cross-sectional area converging from the inside of the passage space 12 to the outer end close to the water-stop wall 11, different height obstacles, water accumulation depths and water flows with different flow velocities are generated; these aquatic organisms (such as fish, shrimps, crabs, etc.) can cross and ascend according to their different biological habits; at the same time, since the height of the conical channel 14 at the center of the passage space 12 is relatively high, a swimming and accumulating rest area can be formed, so that the aquatic organisms can stay in this rest area when crossing the conical channel 14. Therefore, these aquatic organisms can ascend in batches and can avoid the aquatic organisms being separated from the liquid and suffering from hypoxia and death during the ascending process.
[0028] Therefore, from the above description, it can be seen that the present utility model has the following advantages:
[0029] (1) Since the present utility model modularizes the design and manufacture of the corridor body 10, several corridor bodies 10 can be combined to form an ecological corridor, and the corridor body 10 can adjust the interval distance, slope, cross-sectional height, convergence rate, etc. of these arc-shaped grooves 13 and conical channels 14 according to the ecological environment and biological species at different locations of the water retaining weir and overflow weir, so that the ecological corridor can indeed provide passage for organisms and reduce the occurrence of the cutting of biological habitats.
[0030] (2) Since the present utility model is provided with an arc-shaped groove 13 and a conical channel 14 on the corridor body 10 respectively, it can simultaneously provide passage for amphibious organisms and aquatic organisms, and the conical channel 14 can make the water flow at different speeds and accumulate to form a rest area for swimming. Therefore, it can provide multiple species of organisms to use upstream migration and crawling at the same time. Therefore, the present utility model indeed has high practicality.
[0031] (3) Furthermore, since the present utility model can combine several modular corridor bodies 10 to form an ecological corridor, it can be transported to the construction site and assembled according to the geographical environment, height, space, etc. of the weir and overflow weir. Moreover, the quantity and slope can be adjusted according to the on-site environment, which truly has high flexibility, mobility, and rapid assembly.
[0032] (4) Also, since the corridor body 10 of the present utility model is modularly designed, personnel can adjust the interval distance or arc concave ratio of the arc-shaped grooves 13 on the corridor body 10 in advance according to the types of organisms at the installation location, and can also adjust the slope, direction, interval distance, and convergence degree of the conical channel 14 and then manufacture and form it, so that the ecological corridor formed by the present utility model can indeed provide passage for the organisms at that place.
[0033] (5) In addition, since the corridor body 10 of the present utility model is modularly designed, it has high adjustability and mobility, and has greater maintenance flexibility and modifiability. The overall preparation cost is low, the erection speed is fast, and the maintenance is convenient. It can be used in existing engineering structures and can also be used as a temporary corridor during the design and construction of engineering structures. The present utility model can solve the dilemma of the competition and contradiction between engineering development and ecological environment protection.
[0034] As can be seen from the above, the ecological corridor of the present utility model indeed has high adjustability, mobility, maintenance flexibility, and modifiability, and the overall preparation cost is low, the erection speed is fast, and the maintenance is convenient. It can also provide upstream and downstream migration for multiple species of organisms.
[0035] The above is only the preferred embodiment of the present utility model, and it does not impose any form of limitation on the present utility model. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
