Description

[0001] The present invention relates to a dredging device for dredging a river, and a dredging method for dredging the same using a dredging device and an ordinary dredging method using the same.

The present invention relates to a stream dredging apparatus and a method of dredging the stream using the same, and more particularly, to a dredging apparatus for dredging a stream so that the dredging operation of the stream bottom can be always performed, And a method of dredging the river at all times.

In Korea, fluctuation of stream flow is large due to large difference of rainfall year.

In Cheongcheon City, precipitation sediments flow down the river and sediment and accumulate at a gentle velocity, forming a riverbed.

These sediments are large sediments and deep sediments in the area where the water stagnates and near the inflow point of the waste water and sewage.

During the flood, the sediment deposited in the upstream part is washed away and deposited again in the downstream, resulting in a temporal change.

Deposited sediments float into the water as the flow velocity increases. At this time, BOD (Biological Oxygen Demand) and SS (Suspended Solid) in the water increase and the transparency of the stream decreases.

However, when the flow rate is restored to its original state, the flooded sediments are deposited again on the river bed, and these floats and sediments overlap to reach equilibrium.

In the area where many sediments are deposited, sedimentary sediments float, and as the pollutants re-dissolve into the water, the organic matter is decomposed by the microorganisms in the water and consumes the dissolved oxygen in the water, so the water quality deteriorates. In severe cases, Odor and the like.

In addition to organic matter, nutrients such as nitrogen and phosphorus are also eluted, which causes eutrophication in closed water bodies such as lake.

In addition, when the flood occurs, the soil and sediments are deposited in the construction site or in the pond to destroy the habitat, thereby disturbing the aquatic ecosystem and eroding the cross-sectional area. As the water is drained, Deterioration, odor generation, and the like.

At present, a large amount of sediment is deposited in major rivers and lakes in Korea, and the problem of deterioration of the water quality is serious. However, it takes a lot of effort and expense to dredge it and since the sedimentation is repeated after dredging, Subsequently, dredging work has not been actively carried out.

In addition, since the dredging work is a work in water, a large equipment is required for dredging work, and the dredging cost is not only high but also difficult to work, and the efficiency of the dredging work is poor.

Also, there is a problem that the river ecosystem is disturbed due to the forced dredging work which is planned and implemented every year by the central government or the local government.

It is to be understood that the words or words used in the present specification and claims are not to be construed in a conventional or dictionary sense and that the inventor can properly define the concept of a term in order to describe its invention in the best possible way And should be construed in light of the meanings and concepts consistent with the technical idea of the present invention.

Hereinafter, a stream ditching apparatus according to a preferred embodiment of the present invention will be described with reference to FIGS. 1 to 4C.

The river dredging system has a technical feature that dredged sediments including sediments that are deposited in a slow stream area are dredged at all times.

As a result, the streamline cross section can be always optimized, thereby preventing ecosystem disturbance due to deterioration of water quality and increasing efficiency in dredging work.

The continuous dredging apparatus includes a machine chamber 100, a sediment chamber 200, a driving unit 300, a conveying unit 400, and a control unit 500, as shown in FIGS. 2 and 3 .

The mechanical chamber 100 provides a space in which the driving unit 300 is installed, and is provided at one side of the stream.

One side of the stream refers to one side with respect to the direction in which the river flows, and preferably it is the bank (E).

The machine chamber 100 is formed inside the bank E, and an access door 110 is installed at an upper portion for accessing the machine chamber 100.

Next, the sediment chamber 200 is provided on the other side of the river, providing a space that can be accommodated after sediment on the bottom of the river is transported.

At this time, the other side of the stream refers to a position opposite to the machine chamber 100 and refers to the other side with respect to the direction in which the stream flows.

The sediment chamber 200 is also preferably provided in the bank E and an access door 210 is formed in the upper part of the sediment chamber 200 so that the sediment can be transported.

In addition, the sediment chamber 200 is provided with an inlet port 220 through which sediments of the river flow, and an opening / closing door 230 for opening / closing the inlet port 220 is installed.

As shown in FIG. 3, the opening / closing door 230 is installed toward the river, and the sediment flows into the deposit chamber 200 according to the action of the opening / closing door 230.

Although the opening and closing operation of the opening and closing door 230 is not limited in particular, it is preferable that the opening and closing action of the opening and closing door 230 can be elevated in the height direction of the sediment chamber 200.

At this time, although not shown, the opening and closing door 230 may be installed through a structure such as a rack and a pinion, and other known techniques may be applied.

Next, the driving unit 300 generates power for rotating the conveying means 400, and is installed in the machine chamber 100.

The driving unit 300 is preferably provided as a motor.

Next, the conveying means 400 serves to convey sediments at the bottom of the stream to the sediment chamber 200.

The conveying means 400 is installed across the river.

That is, the conveying means 400 is installed perpendicular to the direction in which the stream flows.

The conveying means 400 is not limited to a specific configuration, but is preferably provided as a screw, an auger, or the like so that the conveyance of the deposit can be smoothly performed.

The conveying unit 400 is coupled to the driving unit 300 and is rotated by the driving force of the driving unit 300.

Next, the control unit 500 serves to control the dredging device at all times.

The control unit 500 controls the lifting and lowering of the door 230 of the deposit chamber 200 and controls the driving of the conveying unit 400 through the power control of the driving unit 300.

At this time, the controller 500 includes a water depth sensor 510 and a pressure sensor 520.

The depth sensor 510 is a configuration for sensing the depth of the river, and is a configuration for grasping the deposition state of the deposit through depth sensing.

That is, if it is determined that the river depth detected by the depth sensor 510 is lower than the reference value input into the controller 500, the condition is determined to be a condition for dredging the deposit.

The pressure sensor 520 measures the rotational pressure of the conveying means 400.

That is, if it is determined that the rotational pressure of the conveying means 400 measured through the pressure sensor 520 is higher than the reference value input to the controller 500, the condition is determined to be a condition for dredging the deposit.

The depth sensor 510 and the pressure sensor 520 are configured to automatically perform dredging at all times. The dredging condition is firstly sensed through the depth sensor 510 and the pressure sensor 520 The dredging condition is detected by the second order.

That is, even if the dredging condition is firstly satisfied through the water depth sensor 510, the dredging error is prevented by performing the re-measurement through the pressure sensor 520, so that the dredging operation can be efficiently performed.

On the other hand, a pump 600 is installed on the other bank E of the river.

The pump 600 is a device for pumping water contained in the sediment chamber 200 to the outside.

The sediment chamber 200 is opened and water flows into the sediment chamber 200 through the conveying means 400 so that the sediment can be smoothly discharged from the sediment chamber 200 through the pump 600, So that water in the water tank 200 can be drained to the outside.

The pump 600 includes a drain pipe 610 disposed in the sediment chamber 200 as shown in FIG.

Hereinafter, a dredging process using the river-based dredging apparatus having the above-described structure will be described with reference to Figs. 4A to 5.

As described above, the river continuous dredging apparatus is installed in the river and the bank (S100)

Then, the river water depth is always detected through the water depth sensor 510 (S200)

At this time, the water depth sensing through the water depth sensor 510 can be programmed to be sensed at regular intervals through the controller 500. [

Thereafter, the water depth detected by the water depth sensor 510 is compared with the reference value input to the controller 500 (S300)

At this time, if it is detected that the water depth is below the reference value, the controller 500 operates the driving unit 300 to rotate the screw as the conveying unit 400 (S400)

In other words, the lowering of water depth is considered to be caused by sediment deposition, so that the dredging work can be performed.

However, at this time, it can not be said that sediment is overly deposited because the depth is lowered.

This is because only sediment may be deposited in a specific part of the river floor where the water depth sensor 510 is installed, it is inefficient to dredge the river floor by sensing the water depth sensor 510.

To this end, the rotational pressure of the conveying unit 400 is measured through the pressure sensor 520 while the conveying unit 400 is rotated, and is compared with the reference value input to the controller 500 (S500).

At this time, if it is detected that the rotational pressure value exceeds the reference value, it is determined that the sediment is excessively accumulated, and the actual dredge mode is converted.

4A, the door 220 is lifted up to open the inlet 220 of the sediment chamber 200. In operation S600,

At this time, the water of the river flows into the sediment chamber 200 through the inlet 220.

In addition, the sediment at the bottom of the river flows into the sediment chamber 200 as shown in FIG. 4B by the rotation of the conveying means 400 (S700)

At this time, when the sediments are introduced into the sediment chamber 200 more than a certain amount so that the sediment flowing into the sediment chamber 200 does not flow back to the river, the opening and closing door 230 slightly descends as shown in FIG.

That is, the inflow of the sediment into the sediment chamber 200 is performed by gradually closing the inflow port 220 of the sediment chamber 200.

The lowering of the opening and closing door 230 may further include providing a depth sensor 510 in the sediment chamber 200 and interlocking with the variable depth value in the sediment chamber 200 sensed through the depth sensor 510 .

Next, during the continuous rotation of the conveying means 400, the rotational pressure value of the conveying means 400 is also continuously measured, and when the pressure value is detected below the reference value input to the control unit 500, (S610)

Next, the open / close door 230 of the deposit chamber 200 is completely lowered to close the deposit chamber 200 (S620)

Next, the door door 210 of the sediment chamber 200 is opened to open the inside of the sediment chamber 200, the pump 600 is operated to discharge the water in the sediment chamber 200, The sediment is loaded (S630)

Thereafter, the sediment is transported to a separate disposal site using the transportation means and processed (S640)

This completes dredging work at all times in the stream.

As described above, according to the present invention, there is a technical feature that the dredging apparatus and the dredging method for dredging the river at all times can always perform dredging in a state where the dredging apparatus is always installed in the river.

As a result, the stream cross section of the stream can be always optimized, so that deterioration of water quality due to low quality can be minimized, and ecosystem disturbance due to environmental destruction can be minimized.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
