Description

River stream and cattle composition method {METHOD FOR FORMING RIPPLE AND POOL IN RIVER}

The present invention relates to a method of composition of streams and cows in a river, and more particularly, to a method of providing habitats for a variety of living creatures by placing a waterway guided frame made of environmentally friendly materials at the bottom of the stream to form streams and cows. .

Watersides, such as rivers and rivers, must maintain a complex waterside ecosystem by combining various creatures. However, with the rapid progress of urbanization and industrialization in recent years, waterfront ecosystems such as rivers and rivers are being destroyed, and much effort is required to restore them.

In particular, in urban rivers with a high density of land use, the river environment is being changed for maintenance of reservoirs and reservoirs, linear maintenance of river channels, and construction of river banks for flood control purposes. However, in the case of urban rivers, as the reservoir is strengthened, the curve linearity of the natural river is changed into a straight line, and the lakeside part of the reservoir is concrete, so that the environmental functions (living habitat, hydrophilicity, water midnight, etc.) are virtually disappearing. It is true.

In the case of natural rivers, it is very difficult to provide stable water vegetation zones by providing a haven for various fishes by eroding the periphery of the riverbank due to the rapid flow rate and increase of the flow rate due to the heavy rainfall.

The streams and cattle in the rivers are indispensable for the formation of a diverse and rich natural environment. The stream has a high flow rate, so it has a lot of gravel on the riverbed and is suitable for producing algae. In the early stream, fine-grained soils are lost, forming various spaces between the stones and inhabiting many creatures such as aquatic insects and attached algae. It also provides a good habitat for the fish that feed it, making it a valuable spawning place for fish such as fish. On the other hand, because cows have a slow flow rate, silt is deposited on the riverbed so that the production of adherent algae is low, but the attached algae and aquatic insects produced in the rapid streams flow into the cows and become habitats for organisms that feed them. In addition, since the flow rate is slow and deep, it is used as a place for various habitats and is used not only as a daily resting place, but also as a place for growing, evacuation, and wintering of fry. Therefore, in order to achieve an abundant river environment, it is necessary to properly form shoals and cattle. By the way, in the case of the conventional river, there is a problem that can not properly form the shoals and cattle necessary for the habitat of these various creatures.

The present invention was derived to solve the above problems, by inducing various flows of water in the stream to form a stream and cattle, to provide a habitat environment for a variety of organisms, and to control the erosion of the waterfront to curve the bottom line To provide inducible streams and cattle composition.

In order to achieve the above object, the composition method of the stream and cattle of the river according to the present invention comprises the steps of maintaining the bottom of the river by bypassing the channel of the river; Carrying out a trench at the bottom of the river; Placing a waterway guide frame at the bottom of the river; And filling the filler in the frame. Here, the waterway guidance frame is formed in the height difference is induced by the flow of water to form a shoal and cattle.

In addition, the waterway guide frame is formed higher in both ends than the center portion can induce the flow of water to the center portion.

In addition, an erosion control frame for limiting the erosion area to induce the curve of the lower eyeline may be further disposed at the waterside of the river on the extension line in the water flow direction formed by the waterway guidance frame.

In addition, the erosion control frame may be formed in the "c" shape.

In addition, the waterway guidance frame may be disposed to be inclined to the bottom surface of the river in the direction of water induction.

In addition, the waterway guide frame can be arranged to give a 10% slope to the bottom surface of the river.

According to the present invention, the method of composition of the streams and cows of the river is installed on the bottom of the stream to guide the flow of the water, thereby inducing the flow of water to form the cows and the foxes to provide a habitat environment for various living creatures such as swelling and Sekomiguri. can do.

In addition, the composition method of the stream and cattle of the stream according to the present invention by placing the waterway guidance frame at the bottom of the river and at the same time by placing the erosion control frame in the river water, by controlling the flow of water and erosion of the water to the river bank of the river Curves can provide a habitat for a variety of water vegetation.

Waterway guidance frame 10 used in the stream and cattle composition method of the river according to an embodiment of the present invention is stacked while arranging the cross-beams 12 of the square column type as shown in Figs. The overall shape is raised to form a rectangle. As the wood 12 is stacked, the gaps S at predetermined intervals are formed on the four surfaces of the waterway guidance frame 10, respectively.

As shown in FIG. 2, as shown in FIG. 2, the connecting rod 13 penetrates and the nuts 14 are fastened to both ends thereof, respectively, to the corner portion of the waterway guided frame 10, which is an area where the wood 12 to be laminated intersects. The laminated wood 12 is firmly fixed to each other. In addition, a portion of the wood 12 may be directly fixed to the screw bolt 15 for connecting the wood in close contact with each other.

In addition, the waterway guidance frame 10 is formed at different heights to induce the flow of water. As an example, the wood 12 is additionally stacked at both ends in the longitudinal direction of the waterway guidance frame 10 to form a pair of protrusions 16 upward. That is, the height H1 of the protrusion part 16 of the waterway guide | route 10 is formed larger than the height H2 of the center part (H1> H2). Therefore, when the waterway guidance frame 10 is installed at the bottom of the river, the flow of water is induced to the center portion (the area between the protrusions 16), which is a low height portion. In the present embodiment, only the case where both ends in the waterway guidance frame is high, the present invention is not limited thereto, and may be variously changed. For example, the waterway guided frame may have a protrusion formed at the center portion, and three or more protrusions may be formed.

Wood 12 may be used for preservation-treated primary wood for enhanced durability. In addition, the cross section of the wood may be made in a variety of shapes, such as circular, polygonal, and the overall frame shape of the wood is also variously changed to a variety of shapes, such as triangular frame, hexagonal frame as well as square frame.

As shown in FIG. 3, the filler 20 made of gravel, crushed stone, rubble, and the like is filled in the waterway guidance frame 10. Filler 20 preferably has a size that does not escape the gap (S) of the waterway guide frame (10).

Figure 4 is a perspective view of the erosion control frame according to an embodiment of the present invention, Figure 5 is a view showing a state filled with filler in the erosion control frame of FIG.

As shown in FIG. 4, the erosion control frame 30 used in the stream and cow composition method according to the embodiment of the present invention is laminated with the wood 32 crossing each other as in the waterway guide frame 10. To be assembled. The fastening means between the wood 32 of the erosion control frame 30 is the same as that of the waterway guide frame 10. The erosion control frame 30 is installed on the waterside of the river to limit the erosion area of the waterfront by the water flow action of the waterway guidance frame 10.

The erosion control frame 30 may be formed in a "c" shape to more effectively limit the erosion area of the waterside. That is, the erosion control frame 30 may have protrusions 34 facing each other in the lateral direction of both ends in the longitudinal direction. This erosion control frame 30 is buried to protrude to a predetermined height in the bottom. The erosion control frame 30 is also filled with a filler 20 therein, as in the waterway guide frame 10 (see FIG. 5). However, on the filler 20 in the erosion control frame 30, by installing a vegetation mat fixed in advance by cultivating a suitable plant in the bottom, it is possible to induce a more natural landscape.

6 and 7 are various layout views of the frame according to the composition method of the stream and cattle of the river according to an embodiment of the present invention.

First, referring to FIG. 6, it can be seen that the waterway guide frame 10 and the erosion control frame 30 are disposed by the composition method of the stream and cattle in the stream according to the first embodiment of the present invention. In the present embodiment, the waterway guidance frame 10 alternates with the water flow guidance direction (dashed arrow) alternately at a predetermined angle with respect to the flow direction of the river (solid arrow) at predetermined intervals at the bottom of the river. Are distorted. That is, the waterway guidance frame 10-1 disposed on the path of which the waterway guidance direction is directed to the right is arranged at a predetermined angle θ1 in a clockwise direction to the stream flow direction, and the waterway guidance direction is disposed on the path toward the left. The waterway guidance frame 10-2 is disposed at a predetermined angle θ2 in a counterclockwise direction to the stream flow direction.

The waterway guide barrier 10 arranged as described above is guided by the waterway to the center portion of the region between the protrusions 16 due to the height difference to induce a zigzag waterway, thereby changing the waterway flow rate to form a fox and a cow in the river. .

In addition, the waterway guidance frame 10 may be disposed to be 10% inclined with respect to the bottom surface of the river in the waterway guidance direction in order to more smoothly guide the waterway of the river . In order to induce the water path, first, the area of the flow path (water path) must be secured, so that the direction of the flow is variously induced by forming a zigzag direction of the frame from the upstream to the downstream direction of the stream to the waterside. In this case, the flow path is formed to form a wider or narrower shape in succession. In addition, by adjusting the inclination of the direction from the upstream to the downstream as well as the direction of the frame, the flow velocity is variously distributed according to the formation of the drop between the upstream and the downstream. This creates a variety of habitat environmental conditions that can attract various aquatic organisms.

The erosion control frame 30 is disposed at the waterside of the river on an extension line in the waterway induction direction, respectively. That is, the direction of the waterway is arranged so as to face the center portion (area between the protrusions 34) of the erosion control frame 30. This erosion control frame 30 limits the erosion area of the water surface by the induced waterway, in particular, the water erosion of the area between the protrusions 34 of the erosion control frame 30, and the water surface on which the protrusion 34 is disposed Limit erosion of parts. Therefore, the erosion area is convexly curved toward the erosion control frame 30, as shown in FIG.

Next, referring to FIG. 7, it can be seen that the waterway guide frame 10 and the erosion control frame 30 are disposed by the composition method of the stream and cattle in the stream according to the second embodiment of the present invention. In the present embodiment, in order to guide the waterway of the river in two directions, the waterway guide frame 10 is paired to be inclined at a predetermined angle in pairs, respectively (approximately, "V" type arrangement). Accordingly, the waterway of the river is branched in two directions by the waterway guidance frame 10, the branched guidance waterway is formed to form a support mesh, respectively, as shown by the dotted arrow.

In this way, the waterway guide frame 30 is arranged in various ways to adjust the direction and the number of waterway guide, it can form a stream and cattle in a variety of rivers.

So far, we have examined the arrangement of waterway guide and erosion control frame by the stream and cow composition method, and the following describes the installation process of the stream and cow composition method.

Referring to FIG. 8, first, as a preparatory work for arranging the waterway guidance frame 10 at the bottom of the river, a bypass channel is formed in the river to expose and maintain the bottom of the river, and the waterway guidance frame 10 is buried. After measuring and designating the location, the digging work is carried out using a manpower or an excavator.

Next, to assemble the waterway guide frame 10 to match the wood 12 brought into the site, respectively. The waterway guidance frame 10 may be directly assembled in the field, or the already assembled waterway guidance frame 10 may be brought into the field as it is to be used. Assembled waterway guidance frame 10 is arranged by adjusting the angle according to the desired waterway guidance direction in the pit formed by the digging operation.

Next, after filling the filler 20, such as gravel, crushed stone, rubble, etc. in the waterway guide frame 10, and fills the gap between the waterway guide frame 10 and the pit with soil, etc. of the waterway guide frame 10 Landfilling is complete.

Finally, after removing the bypass channel, restoring the original waterway of the river, and placing the erosion control frame 30 on the designated water surface, the stream and cow composition method of the river is completed. The erosion control frame 30 may be arranged by adjusting the angle according to the degree of erosion and deposition, and protrudes higher than the ground of the waterside. Since the assembly and embedding operation of the erosion control frame 30 is the same as the assembly and embedding operation of the waterway guidance frame 10, detailed description thereof will be omitted.

On the other hand, in the above embodiment, after installing the waterway induction frame 10 first, the erosion induction frame 30 is installed later, after the erosion induction frame 30 is installed first, the waterway induction frame 10 may be installed later. It is also possible to provide both at the same time.
