The present invention relates to a river facility for protecting the ecosystem, and more specifically, to prevent the loss of bank slopes by preventing the river water from flowing to the dike side at a high flow rate, and to provide an ecosystem habitat by forming a region with a low flow rate on the side of the river. It is about the river facilities that can protect the ecosystem.

In general, embankments with plowed soil are formed in rivers, agricultural channels, and lakes to prevent flooding of rivers and promote efficient use of water resources.

The dike thus constructed prevents the collapse of the dike due to water pressure, and its one or both sides are in direct contact with the water surface for engineering reasons such as building a roadway for driving various equipment including a vehicle. All have inclined surfaces.

Since one side or both sides of the embankment forms an inclined surface as described above, the lower side of the inclined surface of the dike is easily eroded by the flow of the river, and in the case of rainy weather or heavy rain, the sediment of the dike is easily moved to the river or the like along the slope. Because of the loss, the supporting strength of the dike is weak, and if the dike is collapsed, it can cause serious casualties or property damage. Therefore, it is installed and used to prevent the erosion of the bank slope and the loss of soil.

The most typical of the conventional revetment means as described above, there is a revetment block that is formed on the inclined surface of the embankment to have a form of square or liver or octagon as a concrete or mortar material.

However, the conventional revetment block as described above is made of concrete or mortar material, the weight is relatively heavy, so that the transport and handling of the revetment block is difficult, and each revetment block must be installed in a manner of fitting by manpower. Therefore, there was a problem that the installation of the raft block on the slope of the embankment was a difficult and difficult task requiring skill. Each area of the raft block was in contact with the slope of the embankment so that a large number of rafts per unit area Of course, the block to be installed, as well as the installation of the revetment block is weak because there is a problem that is separated or lost from the slope by the water flowing through the river or its own weight.

In particular, the installation of the above-mentioned protection block on the inclined surface of the dike having a large area requires a lot of manpower and a long construction period, which leads to an increase in construction cost and delay of air, and a protection block of concrete or mortar. Since herbaceous plants are not able to grow at all, they interfere with the purification of various pollutants introduced into the rivers, causing river pollution, and there is a problem in harmony with the overall landscape of nature.

In order to solve the problems of the above-described protection block of concrete or mortar material, recently, a gabion method using a natural material stone has been applied.

The gabion method is to prevent the loss of the dike by installing a plurality of gabions filled with natural stones in the wire connected crosswise, vertically along the length of the dike on the slope of the dike.

According to the gabion method, the construction is convenient because there is no need to match the gabions close to each other, and the vegetation base is secured by the natural stone has the advantage of recording the slope of the dike.

However, the gabion method according to the prior art has the following problems.

Many of the gabions built on the slopes of the banks are fixed to the slopes of the banks, but each has no binding force. Therefore, each of the gabions has a weak stiffness against the banks. One or more gabions can be pushed down or broken by flowing water, preventing the banks from being protected, resulting in the banks collapsing. In addition, there is a disadvantage in that waste of labor and economic loss occurs as a large cost for restoring damage.

In addition, conventional river protection facilities also have a problem that does not satisfy both the loss of the dike and the ecosystem protection.

The present invention is to solve the above-mentioned conventional problems, to guide the flow of river water flow toward the slope of the dike to prevent the loss of the slope of the dike and to create a space for protecting the ecosystem to protect the ecosystem on the slope side The purpose is to provide.

The present invention for achieving the above object, the ecosystem protection river facilities, the first guide plate to guide the river to turn without hitting the inclined surface of the bank, installed on the first guide plate can be elevated to cope with the water level change of the river water It characterized in that it consists of a second guide plate and a mesh installed in the second guide plate to induce the flow of river water.

The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. Prior to this, terms or words used in the present specification and claims are defined in the technical spirit of the present invention based on the principle that the inventor can appropriately define the concept of the term in order to best describe his or her own design. It must be interpreted to mean meanings and concepts.

As shown in FIG. 1, the ecosystem facilities for protecting the river according to the present invention are installed in a staggered manner in a zigzag form at a distance separated from the river R side formed between the banks 1. It consists of water flow guides (10) to prevent the loss of) and to create ecosystem habitat space (H) on the riverside.

As shown in Figures 2 and 3, the water flow guide 10 is fixed to the bottom of the river and the curved guide portion (11a) (convex toward the bank (1) side to guide the flow of the river water flows to the bank (1) side of the river bank) To guide the flow of the river water while being elevated in accordance with the water level of the river (R) is connected to the first guide plate 11, the first guide plate 11 having a) to flow to the center of the river The guide plate 12 and the second guide plate 12 is provided on the side of the embankment (1) is made of a mesh 13 to create an ecosystem habitat space (H).

The first guide plate 11 is fixed in the water through a plurality of anchors 14 as a base of the water flow guide 10. When only the lower end of the first guide plate 11 is fixed to the bottom of the river (R) can be shaken by the flow of river water, so that the anchor 14 penetrates the first guide plate 11 up and down to prevent the river (R) It is preferable to be embedded in the bottom part and to be fixed.

In addition, at the lower end of the first guide plate 11 and preferably at both end portions, the support bar 15 is configured to maintain the standing state of the first guide plate 11 regardless of the inclination of the bottom of the river R. The end is hinged while maintaining the direction orthogonal to the guide plate 11.

The second guide plate 12 is for guiding the flow of the river water even when the water level of the river R is higher than the height of the first guide plate 11. The first guide plate 11 naturally floats according to the water level. It is installed to be elevated in, and specifically described, the buoyancy generating portion (12a) is made to form a plate-like to float in the river water by buoyancy at the top. The buoyancy generating portion 12a is filled with air so that buoyancy is generated by the air so that the second guide plate 12 floats. The buoyancy generating unit 12a is not limited to air, and any floating means such as styrofoam that can float in the river R is possible.

The guide structure for elevating the second guide plate 12 is as follows. One or more guide rails 11b in the longitudinal direction are formed at one place of the first guide plate 11, and the lifting rollers which are connected to the guide rails 11b to be lifted and lowered at the second guide plate 12 ( 12b) is installed.

The net 13 provides a habitat space for the ecosystem to inhabit in the space formed between the second guide plate 12 and the slope of the embankment 1.

The operation of the river facilities for ecosystem protection according to the present invention is as follows.

As shown in FIG. 1, the water flow guide 10 according to the present invention is arranged in a zigzag form where a predetermined space is spaced apart from the dike 1 on both sides (or one side) of the river R so that the river water of the dike 1 It is possible to foster stream ecosystems through the habitat space (H) where water flow is relatively low without directly hitting the slope.

As shown in FIG. 3, the first guide plate 11 is erected upright in the river water through a plurality of anchors 14. At this time, the anchor 14 penetrates all the portions of the first guide plate 11, the support bar 15 is installed in a direction orthogonal to the first guide plate 11, the first guide plate 11 is Can stand up in water. On the other hand, the reinforcement bar 15 is hinged to the first guide plate 11 can rotate firmly to support the first guide plate 11 while rotating in accordance with the state (tilt) of the bottom of the river (R).

The second guide plate 12 maintains a floating state in the river R by the buoyancy generating unit 12a, and as shown in FIG. 3, when the water level of the river water maintains the height of the first guide plate 11 is increased. The two guide plate 12 maintains the same height as the first guide 11.

In this case, the river water flows to the bank (1) side, and then flows back to the center of the river (R) by taking the curvature of the curved guide portion (11a) of the first guide plate 11, the river water of fast flow rate on the slope of the bank (1) Since it does not hit directly, the loss of the inclined surface of the levee 1 can be prevented.

Some river water flows through the habitat space (H), and since the habitat space (H) has a relatively slow flow rate, vegetation, fish, and the like that grow in the river can be established.

On the other hand, if the river water increases due to heavy rain, rainy season, etc., the water level of the river water is increased. In this case, as shown in FIG. 4, since the buoyancy generating unit 12a always floats on the surface of the river water, the second guide plate 12 tries to ascend, and the second guide plate 12 follows the guide rail 11b. Under the guidance of the rising and lowering roller 12b, it naturally rises.

That is, even when the water level of the river water is increased, the second guide plate 12 can prevent the loss of the levee 1 regardless of the water level of the river by adjusting the overall height of the water flow guide 10 in response to the change in the water level of the river water. will be.

On the other hand, when the river water is reduced in the state of Figure 4, the second guide plate 12 is lowered under the guidance of the lifting roller 12b according to the level of the river water as opposed to the above-mentioned rise time.

As described above, according to the ecological protection river facilities according to the present invention, the river water does not flow to the slope of the dike at a high flow rate can prevent the loss of the dike slope without the installation of a raft block or gabion on the dike slope We can keep molding beauty of.

In addition, the reliability of the product can be improved by guiding the flow of the river water regardless of the level of the river water without using a separate driving force.

In addition, by guiding the flow of rivers, ecosystem habitats can be created where they are not affected by river waters, thereby reducing costs for protecting dikes and fostering ecosystems, and preventing the destruction of river ecosystems. It can have the effect of being able to form.

The invention has been described and illustrated in connection with a preferred embodiment for illustrating the principles of the invention, but the invention is not limited to the configuration and operation as shown and described. Rather, those skilled in the art will appreciate that many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims.
