It is composed of willow trees (1).

Description

Willow tree artificial structure}

This is about an artificial willow tree island to protect the river ecosystem. More specifically, it is about an artificial willow tree island to protect the river ecosystem by planting willow trees in the river so that fish can safely inhabit the willow trees.

When the water in the river increases due to a rainy season or a flood, the flow speed of the river water rapidly increases, and the soil and sand on the river bed are swept away by the torrent, making it impossible for not only fish but also aquatic plants living in the river to live. .This becomes more severe when concrete walls are installed on river embankments. In addition, rivers have a natural environment in which microorganisms, aquatic plants, fish, etc. can live, so they generally have the ability to purify water quality. However, due to indiscriminate development and pollution from agriculture or livestock farming, river pollution is serious. This has emerged as a problem, and as microorganisms and aquatic plants living in rivers disappear, the habitat environment for fish also deteriorates, and the devastation tends to become increasingly severe. In the past, a common way to solve the above problems was to spread rubble or pebbles on the river bottom, but there was a problem that they were lost in the rapid current due to heavy rain or monsoon season and did not play a significant role. In order to prevent scour of such river beds, a technology to install scour prevention blocks, which are concrete regular products, has been proposed. However, according to the conventional scour prevention block, scour of the river bottom can be prevented, but because the scour prevention block is concrete, aquatic plants cannot grow on the river bottom, destroying the river ecosystem. Of course, in recent years, there have been cases of planting aquatic plants on scour prevention blocks, but since this is limited to the river bottom, it is facing limitations in preserving the river ecosystem.

The purpose is to provide an artificial willow tree island to protect the river ecosystem by providing a safe space for fish to live and spawn in the river, thereby encouraging the abundant habitation and reproduction of fish.

It is composed of a plurality of piles connected in a circle and is characterized in that it includes an aquatic weed frame that is driven into the bottom of the river and willow trees that are planted longitudinally and horizontally inside the aquatic weed frame.

By providing a safe space for fish to live and spawn inside the river, fish living in the river can safely live and spawn through the artificial island, thereby preserving the river ecosystem.

The willow artificial island 100 for protecting the river ecosystem according to the present invention has a number of

A water plant frame (20) that provides a space for planting willow trees (1) by means of stakes (10) and is fixed to the river bottom (2), and the stakes (10) constituting the water plant frame (20) are connected to each other. A binding band 30 for binding, and a vegetation soil filling bag 50 that prevents the vegetation soil 40 (shown in FIG. 2), which will be described later, filled inside the water plant frame 20 from falling out of the water plant frame 20. It consists of willow tree (1), which is planted on the aquatic plant frame (20). The piles 10 constituting the aquatic plant frame 20 are in the form of a rod with a pointed portion 11 formed at the lower end, and a plurality of them are arranged in the shape of a circle. The piles 10 arranged in this way can maintain their circular shape by the binding band 30, and the binding structure by the binding band 30 is as follows. The piles 10 are arranged in a row in the shape of a circle, where the binding band 30 binds the two piles 10 that are adjacent to each other and binds the piles 10 in series in the circumferential direction. For example, as shown in Figure 3, when binding four piles (10-1, 10-2, 10-3, 10-4), the first and second piles (10-1, 10-2) are tied together. Binding with a band (30-1), binding the second and third piles (10-2, 10-3) with the second binding band (30-2), and binding the third and fourth piles (10-3, 10- 4) is tied with the third binding band (30-3). Accordingly, the two piles 10 are connected, but the piles 10 are connected in series, so that all the piles 10 are connected, thereby providing great support rigidity against external force. In addition, if some of the piles 10 are damaged, the piles 10 can be replaced after removing only the relevant binding band 30, making maintenance work easy and reducing costs. The vegetation soil filling bag 50 can be made of any material and structure that can prevent the vegetation soil 40 filled in the aquatic plant frame 20 from being lost between the piles 10. For example, the vegetation soil filling bag (50) is in the form of a strip and is erected along the inner peripheral surface of the aquatic plant frame (20).

The present invention can form a forest in a river with willow trees (1) planted in the aquatic plant frame (20) to provide a safe habitat and spawning area for fish in the river. You can. On the other hand, if the flow speed of the river is fast, the impact energy due to the flow speed is large, so the artificial island 100 of the present invention may fall out or break from the river bottom. To solve this problem, as shown in Figures 4a and 4b, an aquatic weed frame is used. At (20), a wave attenuation pipe (60) through which river water passes is formed. The wave force attenuation pipe 60 is a pipe with both ends expanded in the form of a fallopian tube, and a hole through which river water passes is formed inside. The piles 10 disposed above and below the wave force attenuation pipe 60 will not be separated from the wave force attenuation pipe 60 because they are bound to each other. The willow tree artificial island 100 for protecting the river ecosystem according to the present invention constructed in this way looks like a floating island in the river because the willow tree 1 extends sideways and stands upward in the river, and when viewed underwater, it looks like a willow tree. It looks like a forest with trees (1). As the willow tree (1) is shaken by the flow of river water, a safe space with a slow flow rate is created inside the aquatic plant frame (20) as it does not receive much river flow. Fish living in rivers will be able to live or spawn in forests made up of willow trees (1), thus preserving the river ecosystem. Meanwhile, since the artificial island 100 is formed in a curved shape, river water can naturally flow downstream along the curvature of the artificial island 100, and also passes through the hole inside the wave attenuation pipe 60. Therefore, when the flow speed of river water is slow, the fixing force of the pile 10 is greater than the impact energy due to the flow speed, so the artificial island 100 can remain embedded in the river bottom by the pile 10, and the flow speed of river water Even if it is fast, the river water passes through the wave damping pipe 60 and the impact energy applied to the artificial island 100 is not large, so the artificial island 100 can remain installed on the river bottom.
