Description

Dam construction to formation consist of floodgate for sediment purification}

The present invention relates to a dam structure in which the sediment purification gate is formed, and in detail, an outlet through which sediment is discharged is formed at a lower end of the dam, an outlet opening and closing part is installed at an inlet side of the outlet, and a crushing unit is installed at an outlet side of the outlet. And it relates to a dam structure in which the sewer is formed on one side of the dam is provided with a projection on one side, the sediment purification hydrology is formed by a plurality of gabion is installed on one side of the dam.

In general, dams are installed in rivers or seas where there is a lot of water flow, and they are installed in the sea for tidal power generation or downstream of the rivers to prevent the inflow of seawater. It reduces the damage caused by the drought, and discharges the water in case of drought, thereby reducing the damage of the drought, and can additionally generate power by using the force of falling water.

These dams are most often installed in the upstream or midstream of the river. These dams are installed at the inlet or outlet of the main body and the discharge passage through which the water is discharged through the main body. It includes a water gate for controlling the discharge amount, and a downfall portion in which water discharged from the discharge path falls and hits.

At this time, when water is discharged through the dam's discharge path, soil, gravel, etc., which are included in the water from the upstream of the river, and foreign matters that cause pollution accumulate at the bottom of the dam. Will be raised.

In order to solve the above problems, the present invention provides a discharge port through which the sediment is discharged to the lower side of the dam, and installs a discharge opening and closing part to discharge the sediment by opening the discharge port if necessary, and by installing a crushing unit on the outlet side of the discharge port. It is an object of the present invention to provide a dam structure in which the sediment purification hydrology is formed so that the sediment is discharged through the discharge port so that the sediment is crushed and flows in the crushing part.

The present invention for solving the above problems to form a discharge port discharged from the sediment at the bottom of the dam, the outlet opening and closing portion is installed on the inlet side of the discharge port, the crushing portion is installed on the outlet side of the discharge port formed on one side The falling down part is provided on one side of the dam, and a plurality of gabion parts are provided on one side of the falling part.

The present invention is provided with a discharge port through which the sediment is discharged in the lower side of the dam, and the discharge opening and closing portion is installed to discharge the sediment by opening the discharge port if necessary, so that the sediment that is settled for a long time can be discharged, the outlet outlet side A crushing unit is installed at the outlet to prevent the sediment discharged to the outlet from being crushed.

According to the present invention, in a dam installed in a place where water flows, a plurality of discharge passages 11 are formed, and the water gates 12 installed in the discharge passages 11 and driven by the power transmission device 17 flow. Blocking the water to control the flow of water, a plurality of outlets 13 are formed at the bottom to discharge the sediment accumulated in the lower side, the outlet opening and closing portion which is installed at the inlet side of the outlet 13 to open and close the outlet 13 A dam 10 composed of 14;

The dripping portion 20 is installed at the outlet side 11 of the dam 10 and the water discharged from the outlet 11 is dropped, and the protrusion 22 having the protrusion 22 for reducing the flow rate of water is formed at one side. Wow;

Is installed on one side of the downfall portion 20, the gabion portion 30 made of a mesh form on one side of the downfall portion 20; is configured to include.

At this time, in the downfall portion 20, a crushing portion 21 in which the sediment discharged from the outlet 13 of the dam 10 is hit and crushed is disposed at the outlet 13 of the dam 10. Is formed.

In addition, a plurality of dampers 15 made of an elastic material are coupled to the sluice 12 of the dam 10 in a direction perpendicular to both sides thereof, and are interposed between the guide portion and the sluice 12 formed on both side walls of the dam. The waterproof part 16 is provided so that water does not flow out between the lower end of the water gate 12 and the discharge passage 11 of the dam 10.

That is, the present invention will be described in more detail as follows.

A plurality of discharge passages 11 are formed, and the discharge port 13 is formed at the lower end of the dam 10 in which the flow regulating water gate 12 is installed at the inlet of the discharge passage 11 and is settled at the lower end of the other side of the dam. The sediment to be discharged downstream.

Then, when the outlet opening and closing portion 14 is installed on the inlet side of the outlet 13 and the precipitate is deposited and accumulated, the outlet opening and closing portion 14 is opened to discharge the precipitate.

One side of the dam 10 is provided with a downfalling portion 20 in which water discharged through the discharge path 11 is dropped, and a protrusion 22 protruding upward at one end of the downfalling portion 20. Is formed to reduce the flow rate of water, water is reduced in the flow rate due to the protrusion 22 of the downfall portion 20 is provided with a plurality of gabion portion 30 is formed on one side of the downfall portion 20 Do not crush the ground when it falls.

The downfall portion 20 is formed in the concrete plate is the entire surface of the downfall portion 20 to prevent damage to the ground due to water falling from the discharge path 11, the concrete plate at the bottom of the gabion portion 30 It is formed to prevent the ground of the gabion portion 30 is broken and the gabion portion 30 is flowing.

A crushing portion 21 is formed on the downfall portion 20 at the outlet outlet side of the dam 10 so that the sediment discharged from the outlet 13 hits and is crushed, thereby preventing the precipitate from decaying.

In addition, a plurality of dampers 15 formed of an elastic material are coupled to both sides of the water gate installed in the discharge passage 11 of the dam 10 so that the guide portion formed in the dam and the water gate 12 do not directly rub. The waterproof part 16 is coupled to the lower side of the discharge passage 11 of the dam 10 in contact with the lower side of the water gate 12 so that water does not leak when the water gate 12 is closed.
