Description

ecological corridor

This creation is an ecological corridor, especially a modular design, with high adjustability, mobility, maintenance flexibility and amendability. The overall preparation cost is low, the erection speed is fast, the maintenance is convenient, and it can provide Ecological corridors used by various biological species to travel upstream and back.

Due to the limited freshwater resources on the island of Taiwan and the fact that most of them are intercepted by lakes and reservoirs, some streams, ditches and drainage ditches have intensively built dams for regulation and irrigation purposes; and due to the engineering types of these dams Similar to sand control dams, they are horizontal structures, which prevents weirs and sand control dams from effectively achieving the functions of water storage and drainage. In a short period of time, the water depth will easily become shallow due to siltation, and the water temperature will become easily affected by the air temperature, resulting in Due to the lack of a deep water environment, fish die in large numbers due to changes in water temperature during cold snaps in winter, or in summer due to dense aquatic plants covering the water surface, fish cannot survive due to lack of oxygen in the water. At the same time, the ecological habitat has also deteriorated, requiring the use of machinery from time to time. The desilting process has seriously disturbed the ecological environment of the stream and is a waste of public funds.

Examine the horizontal structures set up in lakes and streams. They will cause obstacles to the directional passage of organisms. It is difficult for aquatic organisms to migrate from the lakes or streams into the streams. Therefore, the biological resources will decrease as you go upstream. Due to the renovation of past rivers and drainage ditches, The problem of biological corridors for migratory organisms has not been considered, and the overflow weir has become the largest artificial obstacle. There is a lack of effective biological corridors for upstream fish to use, and due to excessive cementation, excessively steep hard structural bank protection and horizontal Structural differences also prevent aquatic organisms (turtles, turtles, and small mammals) from moving directly vertically, causing them to climb onto land and circle around in search of suitable habitats or waters. This in turn causes these organisms to stray into roads near waters, posing a roadkill hazard. ; In addition, artificial lateral structures such as overflow weirs, water dams, bed fixers, and sand dams will interrupt the communication between water systems, cut off fish habitats, and prevent aquatic biological resources from being connected to each other, which will damage the ecology and It may even lead to ecological catastrophe and species extinction.

The purpose of this creation is to improve the above-mentioned deficiencies in order to provide a modular design that is highly adjustable, mobile, maintenance flexible and correctable, and has low overall manufacturing cost, fast erection speed, and easy maintenance. It can also provide an ecological corridor structure for the upstream and downstream use of various biological species to reduce ecological damage and biological extinction.

In order to achieve the above purpose, the ecological corridor of this creation has a corridor body, with water-stop walls extending on both sides of the corridor body, and a passage space is formed between the two water-stop walls. A plurality of arc grooves are arranged along the water stop wall on one side of the passage space, and a plurality of conical channels are arranged diagonally on the other side of the passage space relative to the arc grooves, so that these conical channels are arranged in the passage space A staircase is formed, and the height and cross-sectional area of the conical channel converge and taper from the inside of the passage space to the outer end of the water stop wall, so that the conical channel forms an inclined shape;

Through the above structure, it is possible to provide a modular design with high adjustability, mobility, maintenance flexibility, and amendability, with low overall manufacturing cost, fast erection speed, easy maintenance, and can provide traceability of various biological species. , Ecological Corridor for Tourist Use

Regarding the technical means and structures used to achieve the purpose of this invention, the detailed description is as follows with reference to the embodiments shown in Figures 1 to 5:

As shown in Figures 1, 2, and 3, the ecological corridor of this invention has a corridor body 10. Water-stop walls 11 are extended on both sides of the corridor body 10, and a water-stop wall 11 is formed between the two water-stop walls 11. A passage space 12. One side of the passage space 12 of the corridor body 10 is provided with a plurality of arc grooves 13 arranged along the water stop wall 11. The other side of the passage space 12 is diagonally arranged with a plurality of arc grooves 13. The conical channels 14 form steps in the passage space 12, and the height and cross-sectional area of the conical passages 14 are tapered from the inside of the passage space 12 to the outer end of the water stop wall 11. , so that the conical channel 14 is formed into an inclined shape.

Following the above, the upper and lower ends of the corridor body 10 are respectively provided with coupling parts (not shown in the figure). The coupling parts (not shown in the figure) can provide for connecting two corridor bodies 10 in series; when the combination When the parts (not shown in the figure) are locating pin holes, the personnel can connect the two corridor bodies 10 in series, and then insert the locating pins into the locating pin holes to connect the two corridor bodies 10 in series, so that the two corridor bodies 10 can be connected in series. These corridor bodies 10 will not separate and fall off.

Through the above structure, according to the ecological types of different dams and overflow weirs, and according to the size and height of the dams and overflow weirs, a single corridor body 10 can be used or a plurality of corridor bodies 10 can be connected in series. Connect and combine (as shown in Figure 4), and then place the upper part of the corridor body 10 on engineering structures 20 such as water retaining weirs and overflow weirs (as shown in Figure 5), and place the lower part of the corridor body 10 on streams, In the lake reservoir, they can be combined to form an inclined ecological corridor.

Then, since the ecological corridor is installed at engineering structures 20 such as water dams and overflow weirs, the water flow on engineering structures 20 such as water dams and overflow weirs can be released through the corridor body 10 and flow down. (As shown in Figure 5), at the same time, the stops of the water stop walls 11 set on both sides of the corridor body 10 are used to make the water flowing through the passage space 12 have a concentrated flow effect; in particular, because the corridor body 10 The conical channels 14 on the top are arranged to form a ladder shape, and the conical channels 14 converge and taper from the inside to the outside, so that when the water flows through the conical channels 14, different flow rates will be generated. The ends of the conical channels 14 As far as the water stop wall 11 is concerned, since the cross-sectional area of the conical channel 14 at the end of the water stop wall 11 is small, the height obstacle formed by it has less impact, so that the flow rate of the water here will be faster and water will not accumulate easily. liquid; as for the front end of the conical channel 14 near the center of the passage space 12, since the cross-sectional area of the front end of the conical channel 14 near the center is larger, a height obstacle will be formed, causing the flow rate of the water liquid to flow through this place. It will reduce and slow down, and the water liquid is blocked by the conical channel 14, so that water liquid will accumulate here to produce a deep water accumulation.

For amphibians (such as turtles, soft-shell turtles) or other mammals in streams and lakes, they can crawl through the passage space 12 provided by the corridor body 10, and the corridor body 10 is provided with a plurality of arc grooves. 13. Through the design of the passage space 12 having both a flat surface and an arc groove 13, amphibians (such as turtles, soft-shell turtles) or other mammals are supported when crawling, thereby reducing their difficulty in movement and making the amphibians more comfortable. Creatures and mammals can crawl upward (or downward) smoothly and move through.

For aquatic organisms (such as fish, shrimps, crabs, etc.), a conical channel 14 is provided through the corridor body 10, and the height and cross-sectional area are determined from the inside of the passage space 12 to the water stop wall 11. The outer ends converge, thus producing different height obstacles, water accumulation depths and water flows with different flow rates; these water creatures (such as fish, shrimps, crabs...etc.) can cross upstream according to their different biological habits; at the same time, due to the passage space 12 The conical channel 14 near the center has a high height, so the water can be accumulated into a rest area for swimming, so that aquatic organisms can stay in the rest area when crossing the conical channel 14, so these aquatic organisms can move upstream in stages, and It can prevent aquatic organisms from being detached from the water during the upstream process and become deprived of oxygen and die.

Therefore, from the above, it can be seen that this invention has the following advantages:

(1) Since this creation is a modular design and manufacturing of the corridor body 10, multiple corridor bodies 10 can be combined to form an ecological corridor, and the corridor body 10 can be installed according to different dams and overflow weirs. The ecological environment and biological species are adjusted to design the distance, slope, cross-sectional height, convergence rate, etc. between the arc grooves 13 and the conical channels 14, so that the ecological corridor can indeed provide biological movement and reduce the cutting of biological habitats. Something happened.

(2) Since this creation is provided with arc grooves 13 and conical channels 14 respectively on the corridor body 10, it can provide passage and movement for amphibians and aquatic organisms at the same time, and the conical channel 14 can also allow water to flow. Different flow rates and swimming accumulation are generated to form a rest area, so that various species of organisms can use upstream migration and crawling at the same time; therefore, this creation is indeed highly practical.

(3) Furthermore, since this invention can combine multiple modular corridor bodies 10 to form an ecological corridor, the corridor can be configured according to the geographical environment, height, space, etc. of the water dam and overflow weir. The road body 10 is transported to the case site and then assembled, and the quantity and slope can be adjusted according to the on-site environment, making it highly flexible, maneuverable and fast to assemble.

(4) In addition, since the corridor body 10 of this creation is of modular design, personnel can adjust the distance between the arc grooves 13 or the concave ratio of the arc grooves 13 on the corridor body 10 in advance according to the biological species of the setting location. The slope, direction, spacing distance, degree of convergence or re-manufacturing of the conical channel 14 can be adjusted so that the ecological corridor formed by this creation can truly provide the passage of organisms there.

(5) In addition, because this creation adopts the modular design of the corridor body 10, it is highly adjustable, mobile, and has greater maintenance flexibility and revisability. The overall preparation cost is low, the erection speed is fast, and the maintenance is It is convenient and can be used in existing engineering structures or as temporary corridors during the design and construction of engineering structures. This invention can actually solve the dilemma of competing conflicts between engineering development and ecological environment preservation.

Therefore, from the above, it can be seen that the ecological corridor of this creation is indeed highly adjustable, mobile, maintenance flexible and modifiable, and the overall preparation cost is low, the erection speed is fast, the maintenance is easy, and it can provide a variety of biological species It can be used retroactively and retroactively; therefore, this creation is indeed progressive and practical, and its method is indeed unprecedented. It sincerely meets the requirements for a new patent. I file a patent application in accordance with the law and pray for the patent to be granted. I am most grateful. Convenience.
