The present invention relates to an erosion prevention structure for preventing erosion of grain streams, and more particularly to the stream by the impact pressure and erosion force received by the inner surface of the bent portion bent outward by the pressure of the water stream to go straight in the grain stream The present invention relates to an erosion prevention structure for preventing erosion of grain streams that prevents river banks from being scoured and collapsed by installing erosion guards at the bends of river banks to prevent the banks from being dug.

In general, one side of the river bank embankment or embankment or drainage channel is used to install a raft block and gabion having various sizes.

Gabion is a construction method that wraps a pile of stones with wires and secures it to the ground.The air and water drainage of the soil flows smoothly between the gaps, but the appearance is not beautiful and the budget is high, and many problems such as natural destruction due to stone production There is this. In particular, in the state of being installed on the weak ground, the case of the dike is frequently avoided due to the severe flooding, avoiding the construction.

In addition, the flow velocity of the stream acts directly on the outer wall to erode and scour at the portion formed such that the wall of the dike wall or the reservoir flows along the curve of the river. When a scour occurs, maintenance is expensive and maintenance is difficult.

Typically, the bent portion of the river bank, which is formed by piled up soil, may be damaged by the flow of the river, or the soil may be lost due to the loss of soil. In order to solve this problem to install an erosion protector for scour prevention, the erosion protector is prone to breakage and fall off after a long time.

And there is a problem that the lifting occurs between the erosion guard and the original embankment.

The present invention has been made in order to solve the problems as described above, install a fixed box body and a cover plate for preventing erosion in the curved portion between the river bank, between the fixed box body and the cover plate installed on both sides of the river In order to prevent the erosion of the grain stream which prevents the fixed box body from escaping toward the river, the flow rate reduction band is installed to reduce the flow rate, and the speed reduction band firmly supports the fixed box body and the cover plate on both sides. It is an object to provide a preventive structure.

The present invention is formed in the size of the three pieces of the sequential order sequentially inside the body of the box-shaped one side and the top is open in order to achieve the above object, the fixing groove is formed toward the cover plate Fixed box body; The vertical plate is fixed between the lower plate and the upper plate, and the vertical plate covers one open side of the fixed box body, and the lower plate overlaps the bottom plate of the fixed box body and is fixed by an anchor, and the upper plate is opened by the fixed box body. A cover plate covering a portion of the upper surface and having three fixing holes sequentially sized in the vertical plate; The first damping plate is fixed on the bottom fixing plate in the upstream of the river, and the second damping plate is fixed on the rear of the first damping plate, and the third lowering plate is fixed to the rear of the second damping plate, and the first and second damping plates are fixed. The reduction plate and the third reduction plate are sequentially formed to have a large size, and the flow holes are alternately formed in the first reduction plate, the second reduction plate, and the third reduction plate, and the first reduction plate, the second reduction plate, and the third reduction plate. A flow rate reduction band having both ends penetrated through the fixing holes of the vertical plate to fit the size and inserted into the panel fixing part to be fixed by bolts; It provides an erosion prevention structure for preventing the erosion of grain rivers, characterized in that consisting of; stone is filled in the space between the fixed box body and the cover plate.

Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

The terms or words used in this specification and claims are not to be construed as being limited to the common or dictionary meanings, and the inventors may appropriately define the concept of terms in order to explain their invention in the best way. Based on the principle, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

The present invention installs the erosion prevention 100 in the bend (2) of the river bank (1), the erosion prevention 100 is a fixed box body 10 and the cover plate 20 in both rivers anchor 25 And a flow velocity reduction band 30 is installed between the fixed box bodies 10 installed at both sides of the river to firmly support the fixed box body and to reduce the flow rate of the river banks at the river bend. It is characterized by preventing.

The fixed box body 10 is formed in a size in which the three paneling parts 11 are sequentially increased in a box-shaped body in which one side and an upper surface are opened, and the fixing groove 12 is formed in the paneling part 11. It is formed toward (20). The fixed box body 10 is installed to face each other in both rivers, and a flow rate reduction zone 30 is installed at the bottom of the river. The plate fixing part 11 is formed to protrude upward from the bottom plate 13, and a plurality of bolt holes are formed at the side thereof.

The cover plate 20 is fixed to cover the open portion of the fixed box body 10 by fixing the vertical plate 23 between the lower plate 22 and the upper plate 21.

The vertical plate 23 of the cover plate 20 covers one open side of the fixed box body 10, and the lower plate 22 overlaps under the bottom plate 13 of the fixed box body 10 to anchor 25. Is fixed. The upper plate 21 covers a part of the open upper surface of the fixed box body 10, and three rectangular fixing holes 24 are formed in the vertical plate 23 to increase in size sequentially, thereby reducing the flow rate reduction band 30. Both ends of the first reduction plate 31, the second reduction plate 32, and the third reduction plate 33 are inserted into and fixed to the fixing bolt 14.

The flow rate reduction zone 30 is fixed to the first bottom plate 31 in the upstream direction of the river on the bottom fixing plate 34, the second bottom plate 32 is fixed to the rear of the first bottom plate 31, The third reduction plate 33 stands up and is fixed behind the second reduction plate 32.

A plurality of anchor holes are formed in the bottom fixing plate 34 of the flow rate reduction zone 30 and fixed to the river bed by the anchors 36.

The first reduction plate 31, the second reduction plate 32, and the third reduction plate 33 are formed to increase in size sequentially, and the first reduction plate 31, the second reduction plate 32, and the third reduction plate The flow holes 37 are alternately formed in the plate 33. In this way, when the stream water in the lower portion of the river passes through the flow holes 37 formed in such a manner, the flow rate is reduced, because the flow is not straight but crosses.

Both ends of the first reduction plate 31, the second reduction plate 32, and the third reduction plate 33 penetrate through the fixing holes 24 of the vertical plate 23 suitable for size, respectively, and are inserted into the fixing portion 11. It is fixed by the fixing bolt (14).

Since the flow rate reduction zone 30 firmly supports the fixed box bodies 10 on both sides, the fixed box body 10 is firmly supported in both sides of the river unless the flow rate reduction zone 30 is broken and broken.

The stone 40 is filled in the space between the fixed box body 10 and the cover plate 20 to give a load to the fixed box body 10 to support it firmly. At this time, the stone 40 is maintained without being lost to the outside by water.

As described above, the present invention reduces the speed of rapid streams of grain streams to prevent the loss of river embankments by rapid streams of water, and secures the fixed box body installed on both sides of the streams. It is effective in preventing the sieve from being pushed toward the river.

Rapids collide with the vertical plate 23 of the cover plate 20 covering the open river side of the fixed box body so that rapids do not strike the river banks directly, preventing erosion of the river banks.

Flow holes in the flow rate reduction zones are staggered to slow down the speed of the river water passing through the flow holes, and the stream waters passing over the flow rate reduction zones are slowed down by the flow rate reduction plates that are sequentially increased to reduce the rapid phenomenon occurring in the curved river. It works.

The weight is supported by the stones filled inside, and the stones are not lost, so they are not lost by water.
