1 to 5, the exposed ecological passage assembly 100 for amphibians according to the present invention is composed of a channel member 110, a well forming layer 130 and a cover 150.

The channel member 110 is preferably made of concrete, and is configured to include a bottom portion 111 and a pair of side walls 113 extending upward at intervals from both sides of the bottom portion 111, and An opening 115 is formed there. Accordingly, the channel member 110 has a "U"-shaped cross section, and an ecological passage is formed along the inside.

Steps 117 are formed along the inner edges of the upper ends of the pair of side walls 113 .

As shown in FIGS. 1 to 5, an “L” shaped flexible angle 170 is installed on the step portion 117. The flexible angle 170 supports the lower edge and both sides of the cover 150 to cushion not only vertical shocks acting on the cover 150 but also horizontal shocks. The flexible angle 170 is preferably made of rubber such as natural rubber or synthetic rubber. In some cases, as the flexible angle 170, a plastic with low hardness may be used.

The well-forming layer 130 is installed in layers on the bottom portion 111, and a plurality of wells 132 in which water may be stored are formed at intervals on the upper surface thereof. Referring to FIGS. 4 and 5 , the well 132 is formed to have an irregular shape at intervals to form a natural ecological passage. It goes without saying that irregularly shaped wells 132 such as circular, elliptical, or quadrangular may be installed between the irregularly shaped wells 132 . These wells 132 are preferably formed so that relatively deep and relatively shallow depths are mixed, and even in the same well 132, the depth of the bottom changes from the edge to the center. The maximum depth of the well 132 is preferably formed to be about 10 to 20 mm. In this way, by varying the shape and depth of the well 132, it becomes a much more natural ecological passage than forming the same shape with the same depth.

In the well-forming layer 130 as described above, it is preferable to form a well 132 on the surface by compressing a pressing member having a protrusion protruding downward on the concrete powder poured on the bottom portion 111, This will be explained in more detail later.

The cover 150 spans the pair of side walls 113 to cover the opening 115, and has a plurality of through holes 152 formed at intervals so that sunlight can shine into the channel member 110. For example, if the size of the cover 150 is a rectangle with a width of 340 mm and a length of 1000 mm, and the width spanning both side walls 113 is 20 mm, the through hole 152 has a width of 150 mm and a length of 20 mm. Slots of mm may be formed along the central portion of the cover 150 at intervals of about 20 mm.

The through hole 152 as described above is such that only about 20 to 35% of the sunlight shining on the cover 150 of the portion disposed directly above the bottom portion 111 passes through the cover 150 and shines into the channel member 110. It is desirable to form To this end, the total area of the entire through hole 152 formed at intervals is about 20 to 35% of the inner planar area of the bottom portion 111 of the channel member 110.

In the exposed ecological passage assembly 100 for amphibians as above, a rubble compaction layer 20 is formed at the bottom of the road 10, a channel member 110 is installed thereon, and the step portions 117 on both sides are flexible. After mounting the angle 170, the cover 150 may be installed on the flexible angle 170.

6A to 6E are cross-sectional views of a channel member sequentially showing a process of forming a well-forming layer on a channel member according to the present invention, and FIG. 7 is a process diagram for explaining a process of forming a well-forming layer on a channel member according to the present invention. to be.

First, as shown in FIG. 6A, a "U" having a bottom portion 111 and a pair of side walls 113 extending upward at intervals from both sides of the bottom portion 111 and having an opening 115 formed at the top. "Make a channel member 110 having a cross-sectional shape (S1). The channel member 110 can be mass-produced by injecting concrete into a mold in a factory.

Then, as shown in FIG. 6B, the concrete powder layer 130 is formed by pouring concrete powder in layers on the bottom portion 111 of the channel member 110 (step S2). Here, "concrete powder" means a mixture of cement, mortar, or cement with sand and small gravel (about 20 mm or less in size).

Before the concrete powder layer 130 hardens, the pressing member 30 protrudes downward and has a protrusion 32 in the shape of a well 132 to be formed, as shown in FIG. 6C, pressed onto the concrete powder layer 130. Do (S3). Preferably, as the pressing member 30, one having a plurality of protrusions 32 formed in an irregular shape at intervals is used.

After maintaining the state of FIG. 6c until the concrete powder layer 130 hardens to some extent, when the pressing member 30 is separated from the concrete powder layer 130, as shown in FIG. 6d, the upper surface of the concrete powder layer 130 A plurality of wells 132 are formed at intervals (S4).

Thereafter, the concrete powder layer 130 is cured until it is firmly hardened (S5), and pre-manufactured "L" shaped flexible angles 170 are mounted on both side steps 117, respectively, and the cover 150 is placed thereon. ) is installed (S6) to complete the exposed ecological passage assembly 100 for amphibians according to the present invention as shown in FIG. 6e.

8 is a cross-sectional view showing a modified example of an exposed ecological passage assembly for amphibians according to the present invention.

In some cases, a protruding passage 119 is formed along the central portion of the bottom portion 111 so as to protrude from the bottom portion 110 to the top of the well-forming layer 130 inside the channel member 110, so that water is disliked. It is possible to provide a passage through which animals can move. The well-forming layer 130 described above is disposed along both side surfaces of the protruding passage 119 .

In some cases, the protruding passage 119 may be formed along both edges of the bottom portion 111, and the well-forming layer 130 may be disposed between the protruding passages 119 on both sides.

In some cases, the protruding passage 119 may be formed only along one edge, and the well-forming layer 130 described above may be disposed along the side.

The rest is the same as described above.

9 to 11 are cross-sectional views showing examples of flexible angles according to the present invention.

As shown in FIG. 9, the flexible angle 170 may be made of only rubber. The flexible angle 170 made of rubber is suitable for use in the exposed ecological corridor assembly 100 for amphibians installed across roads where vehicles of relatively small weight pass or vehicles pass at low speeds. .

In the flexible angle 170 shown in FIG. 10, a rubber layer 174 is formed along the surface of an “L”-shaped core material 172, and a road where a relatively heavy vehicle passes or a vehicle travels at high speed. It is suitable for use in the exposed ecological passage assembly 100 for amphibians installed across the. By inserting the core material 172 into the rubber layer 174, the flexible angle 170 can provide high support rigidity. As the “L” shaped core 172, metal materials such as stainless steel, aluminum, steel plate, and alloy plate are suitable.

Referring to FIG. 11 , holes 173 are formed at intervals in the core material 172 at times, and the rubber layer 174 attached to both sides of the core material 172 through insert injection or the like passes through the through hole 173. It can be connected as one unit. In this way, even if a part of the rubber layer 174 on one surface is damaged, the rubber layer 174 is not easily separated from the core material 172.

In addition, protrusions 175 may be formed on the surface of the rubber layer 174 in contact with the bottom surface of the cover 150 described above so that moisture between the bottom surface of the cover 150 and the rubber layer 174 can be well dried.

In some cases, the flexible angle 170 described above may be made of plastic having relatively low hardness instead of rubber.

The present invention is installed in valleys or flatlands built for road construction, where there is a small water level difference on both sides while the road passes through agricultural waterways or streams, and points where it is necessary to connect hills and rivers, wetlands, and rice fields, which are important habitats for small animals. can be used

In addition, the present invention is most suitable as an ecological passage for amphibians and reptiles, but can be used as an ecological passage for medium and small animals such as medium and small mammals and birds.

Occasionally, having a protruding passage formed to protrude to the upper part of the well-forming layer can be used to install an ecological passage so that animals that do not like water can pass together.
