Description

고효율 친환경 준설토사운반장치 및 이를 이용한 토사배출방법{A high efficient dredged sand carrier and discharing method using the same}A high efficient dredged sand carrier and discharing method using the same}

본 발명은 해양에서 준설된 토사를 제방으로부터 멀리 떨어진 육지 내부의 매립지까지 효율적으로 이송하기 위한 준설토사운반장치(토사운반선에 설치) 및 이를 이용한 토사 배출 방법에 관한 것이다.The present invention relates to a dredged soil transport device (installed on a soil transport ship) and a method for discharging soil using the same for efficiently transporting dredged soil from the ocean to a landfill in the land far from the bank.

일반적으로 준설은 하천, 호수, 강 등에서 준설하는 육지 준설과 바다에서 준설하는 해양 준설이 있다.In general, dredging includes land dredging in rivers, lakes, rivers, etc. and dredging in seas.

해양 준설된 토사의 배출방법은 크게 세 가지로 구분된다.There are three ways to discharge dredged sediment in the ocean.

제 1 방법은 선저가 개방되는 토사운반선으로 해안 가까이 토사를 이송한 후, 선저 해치를 개방하여 일단 토사를 배출한 후 이를 펌프준설선으로 재흡입하여 배출관을 통해 제방 너머로 이송하는 방법이고,The first method is a method of transporting the soil close to the shore by the soil carrier ship in which the bottom is open, and then open the bottom hatch to discharge the soil, and then re-suction it into the pump dredger to transfer over the bank through the discharge pipe,

제 2 방법은 토사가 선적된 토사운반선을 해안 가까이 이동하여 제방에 접안시킨 후, 선적된 토사를 크레인, 포크레인, 덤프트럭 등으로 이송하는 방법이며,The second method is a method of transporting the earth and sand ships loaded with earth and sand close to the shore and docked on the embankment, and then transported the earth and sand loaded by crane, fork crane, dump truck, etc.

제 3 방법은 토사가 선적된 토사운반선을 해안 가까이 이동하여 제방에 접안시킨 후, 언로더 펌프선으로 해수와 토사를 혼합하면서 원심펌프를 이용하여 흡입하여 배출관를 통하여 이송하는 방법이다.The third method is a method of transporting the earth and sand ships, which have been shipped, close to the shore, and docking them on the banks. Then, the seawater and soils are mixed by the unloader pump ship and sucked using a centrifugal pump to be transported through the discharge pipe.

그러나 제 1 방법은 해양 오염이 심해 사용되지 않고 있으며, 제 2 방법은 비용이 많이 들고 공사기간이 길어 사용되지 않으며, 현재 주로 제 3 방법이 사용되고 있다.However, the first method has not been used because of severe marine pollution, the second method is expensive and long construction period is not used, and the third method is mainly used.

제 3 방법의 경우에, 준설된 토사는 아무런 장치가 없는 토사운반선에 실려서 육지 가까이 이송된다.
이렇게 이송된 토사는 토사운반선과 접안된 언로더 펌프선에 의해 흡입장치를 통하여 해수와 함께 혼합되면서 흡입되어 이송되게 된다.
이 때 선적된 토사와 해수의 교란을 위해 고압의 해수가 분사된다.
하지만, 이 방식은 선적된 토사 상단에서 흡입하기 때문에 흡입수두가 대단히 높다. 이는 배출수두의 손실로 이어져 토사를 멀리까지 이송하지 못하며 효율이 떨어지는 이유가 된다.
또한 토사운반선 상부에서 흡입되므로 토사운반선의 바닥에 있는 토사는 흡입구와 선창 하부 상면 사이의 틈새로 공기가 흡입되어 토사를 완전히 배출하지 못하게 되고 필연적으로 토사운반선에 선적된 토사의 20~30%를 남기게 된다. 따라서 토사운반선을 다 비우지 못하고 준설지역으로 돌아가게 되므로 작업효율이 떨어지는 문제점이 있다.In the case of the third method, the dredged soil is transported close to land on board the soilless transport ship without any equipment.
Soil transported in this way is sucked and transported while being mixed with the sea water through the suction device by the unloader pump ship docked with the earth and sand carrier.
At this time, high-pressure seawater is sprayed to disturb soil and seawater.
However, the suction head is very high because it sucks from the top of the loaded soil. This leads to a loss of head, which prevents soil from being transported far and is a reason for inefficiency.
In addition, since it is sucked from the upper part of the earth and sand carrier, the earth and sand in the bottom of the earth and sand carrier are sucked into the gap between the suction port and the upper surface of the lower part of the dock to prevent the soil from being completely discharged. do. Therefore, there is a problem in that the work efficiency is lowered because the soil transport ship is not empty and returns to the dredging area.

본 발명은 상기 문제점을 해결하기 위한 것으로, 본 발명의 목적은 토사운반선에 장착되는 장치로서 외부의 펌프준설선과 조합하여 토사운반선에 의해 매립 대상지로 운반된 토사를 남김없이 모두 배출할 수 있는 준설토사운반장치를 제공하는 것이며, 또한 종래의 토사배출방법과 비교하여 효율적이고 경제적이며 단위시간당 토사배출량의 증대 및 장거리 이송이 가능한 준설토사 배출방법을 제공하는 것을 목적으로 한다. The present invention is to solve the above problems, an object of the present invention is a device mounted on the earth and sand transport ship dredged soil which can discharge all the earth and sand transported to the landfill destination by the earth and sand transport ship in combination with the external dredging ship It is an object of the present invention to provide a conveying apparatus, and to provide a dredged soil discharge method that is efficient and economical, and increases the amount of soil discharge per unit time and can be transported over a long distance compared to a conventional soil discharge method.

본 발명은 상기 기술적 과제를 달성하기 위하여,
토사운반선에 장착되는 준설토사운반장치는 토사운반선의 선창 하부 상면에 해수흡입구가 선수 측에 위치하고 배출단이 선미 측에 위치하도록 종방향으로 설치되는 메인흡입파이프, 해수 흡입량을 조절하기 위하여 상기 메인흡입파이프의 해수흡입구 측에 형성된 해수흡입조절밸브, 토사를 흡입하기 위하여 상기 메인흡입파이프에 횡방향으로 연결되되, 메인흡입파이프의 종방향으로 이격되어 다수 설치되는 토사흡입파이프, 토사 흡입량을 조절하기 위하여 상기 토사흡입파이프에 형성된 토사흡입조절밸브 및 토사를 교란시켜 토사의 흡입을 원활하게 하기 위하여 상기 토사흡입파이프의 토사흡입구 부근에 해수를 분사하도록 다수 설치된 해수분사노즐을 포함하여 구성되도록 하였다.
또한 상기 메인흡입파이프의 배출단에는 토사운반선의 선미 측에 설치된 배출펌프 또는 외부의 펌프준설선의 흡입구와 연결되도록 하는 연결관을 설치하여 흡입된 토사를 배출할 수 있도록 하였다.The present invention to achieve the above technical problem,
The dredged soil transportation device mounted on the earth and sand carrier is a main suction pipe installed in the longitudinal direction so that the sea suction port is located on the bow side and the discharge end is located on the stern side on the upper surface of the dock bottom of the earth and sand carrier, and the main suction is used to adjust the sea water suction amount. Seawater suction control valve formed on the sea suction port side of the pipe, connected to the main suction pipe in the transverse direction to suck the soil, the soil suction pipe which is installed in a plurality of spaced apart in the longitudinal direction of the main suction pipe, to adjust the soil suction amount In order to facilitate the intake of the soil by disturbing the soil intake control valve formed in the soil intake pipe and the soil in order to facilitate the intake of the soil inlet to be configured to include a plurality of sea water spray nozzles are installed to spray the sea water.
In addition, the discharge pipe of the main suction pipe was installed to be connected to the inlet of the discharge pump or the pump dredger of the external pump dredger installed on the stern side of the earth and sand to discharge the sucked soil.

본 발명의 효과는 다음과 같다.The effects of the present invention are as follows.

첫째, 토사흡입조절밸브를 이용하여 토사운반선에 종경사(트림)를 주면서 토사를 배출할 수 있으므로 종래의 토사배출방식보다 효율적으로 토사를 완전히 배출할 수 있어 잔여 준설토사를 거의 남기지 않게 된다.First, since the earth and sand can be discharged while giving a vertical slope (trim) to the earth and sand transport valve using the earth and sand suction control valve, the earth and sand can be discharged more efficiently than the conventional earth and sand discharge method, thereby leaving little residual dredged soil.

둘째, 토사운반선의 선창 하부 상면에 본 발명의 준설토사운반장치가 설치되기 때문에 흡입수두가 낮아지고 상대적으로 배출 수두가 높아지므로 같은 용량의 펌프를 사용할 때 종래의 토사배출방식보다 더욱 멀리 토사를 이송시킬 수 있다.Second, because the dredging soil sanding device of the present invention is installed on the upper surface of the bottom of the dock of the earth and sand transporter, the suction head is lowered and the discharge head is relatively high, so when the same capacity pump is used, the soil is transported farther than the conventional soil discharge method. You can.

셋째, 종래의 언로더 펌프선을 이용하는 토사배출방식(제 3 방법)보다 동일 조건에서 많은 토사를 장거리로 이송하여 배출할 수 있으므로 공사기간을 단축할 수 있고 비용을 절감할 수 있다.Third, since a large amount of soil can be transported and discharged over a long distance under the same conditions as the conventional soil discharge method (third method) using the unloader pump ship, the construction period can be shortened and the cost can be reduced.

넷째, 토사흡입파이프가 선창 하부 상면에 있어 토사가 상부부터 배출하지 않게 되므로 토사를 갑판보다 높게 적재할 수 있어 종래의 방식보다 일회 토사 운반량을 최대로 할 수 있으므로, 즉 이송 효율을 최대로 할 수 있다.Fourth, the soil suction pipe is located on the upper surface of the lower part of the dock, so that the soil is not discharged from the top, so the soil can be loaded higher than the deck, so that the one-time soil transport can be maximized than the conventional method, that is, the transport efficiency can be maximized. have.

다섯째, 외부의 펌프준설선에 연결하여 사용하므로 종래의 토사운반선을 일부 개조하여 재활용 할 수 있다.Fifth, since it is used by connecting to an external pump dredger can be recycled by partially modifying the conventional soil carrier.

본 발명을 보다 명확하고 용이하게 설명하기 위하여 이하 본 발명의 최선의 실시예를 첨부도면에 의하여 상세하게 설명하며, 본 발명에 따른 실시예는 여러 가지 다른 형태로 변형될 수 있으므로, 본 발명의 범위가 아래에서 설명되는 실시예에 한정되지는 않는다.BRIEF DESCRIPTION OF DRAWINGS To describe the present invention more clearly and easily, the following describes the best embodiments of the present invention in detail with reference to the accompanying drawings.

상기 토사흡입파이프(5)에서 메인흡입파이프(3)와 연결되지 않는 일단부는 토사흡입구(9)로서 작용하게 되는데, 보다 효과적인 토사 흡입을 위해 상기 토사흡입파이프(5)의 토사흡입구(9) 측 일단부는 토사흡입구(9)가 선창 하부 상면을 바라보도록 굴곡되게 형성되도록 하며, 또한 토사흡입구(9)의 입구 부분이 더 넓게 벨마우스 형태로 형성되도록 한다.
토사 흡입양을 조절하기 위하여 상기 토사흡입파이프(5)에는 토사흡입조절밸브(6)가 형성된다. 이 때 상기 토사흡입조절밸브(6)의 밸브조절핸들(6')은 토사운반선의 갑판보다 높게 연장되어 설치되도록 함으로서, 도 6b에 도시된 바와 같이 토사를 갑판 위로 봉분처럼 쌓을 수 있게 되어 토사운반선의 운반효율을 높일 수 있게 된다.On the bow side of the main suction pipe 3, ie, on the sea suction port 3 'side, a seawater suction control valve 4, Seachest Valve, which can adjust the degree of opening and closing by electric or hydraulic pressure, is formed.
The seawater suction control valve (4) can be appropriately adjusted to the suction situation of the seawater it is possible to adjust the mixing rate of the seawater and the soil inhaled. In order to suck the soil, it is connected to the main suction pipe (3) in the lateral direction, and the soil suction pipe (5) is installed a plurality of spaced apart in the longitudinal direction of the main suction pipe (3), the soil suction pipe (5) It may be installed in a branch (branch) so as to be symmetrical about the main suction pipe (3).
One end of the soil suction pipe (5) that is not connected to the main suction pipe (3) acts as the soil suction hole (9), and the soil suction hole (9) side of the soil suction pipe (5) for more effective soil suction. One end portion is to be formed to be bent so that the soil inlet 9 is to face the upper surface of the lower dock, and also the inlet portion of the soil inlet 9 is formed in a wider bell mouse shape.
The soil suction suction control valve 6 is formed in the soil suction pipe 5 to adjust the soil suction amount. At this time, the valve control handle 6 ′ of the earth and sand suction control valve 6 is installed to extend higher than the deck of the earth and sand conveying line, so that the earth and sand can be stacked on the deck as shown in FIG. It is possible to increase the transport efficiency.

상기 메인흡입파이프(3)에 가지(branch) 형으로 설치된 토사흡입파이프(5) 및 토사흡입조절밸브(6)를 이용하여 흡입양을 조절하면서 토사를 흡입하게 된다.
이 때 상기 토사흡입파이프(5)의 토사흡입구(9) 부근에는 해수를 분사할 수 있도록 해수분사노즐(8)을 설치하여 토사를 교란시켜 해수와 섞이게 함으로서 토사의 흡입을 보다 원활하게 한다.
상기 해수분사노즐(8)은 선창 하부 상면에 종방향으로 설치된 해수공급파이프(8')에 연결되어 설치되는데, 상기 해수공급파이프(8')의 선미측 일단부에 설치된 해수공급펌프(미도시)에 의해 해수공급파이프(8')를 통하여 해수분사노즐(8)로 해수가 공급되도록 하여 토사흡입파이프(5)의 토사흡입구(9) 부근의 토사를 교란시킬 수 있게 된다.By using the soil suction pipe 5 and the soil suction control valve 6 installed in the branch (branch) type in the main suction pipe 3 to adjust the suction amount to suck the soil.

본 발명에 따른 준설토사운반장치가 장착된 토사운반선을 이용하여 선적된 토사를 배출하는 방법을 살펴보도록 한다.
도 5는 본 발명에 따른 준설토사운반장치가 장착된 토사운반선과 외부의 펌프준설선을 이용한 토사 배출작업도를 도시한 것이며, 도 9는 준설토사배출에 관한 작업 흐름도를 도시한 것이고, 도 2 내지 4의 도면부호를 참고하여 토사배출방법을 설명하도록 한다.Let us look at the method of discharging the earth and sand shipped using the soil sanding ship equipped with a dredging soil sanding device according to the present invention.
5 is a view illustrating a soil discharge operation using a dredged soil carrier and an external pump dredger equipped with a dredged soil carrier according to the present invention, and FIG. 9 is a flowchart illustrating a dredged soil discharge operation. The soil discharge method will be described with reference to FIG. 4.

우선 지정된 준설해역에서 준설선을 이용하여 해저를 준설하게 되고, 준설된 토사를 본 발명에 따른 준설토사운반장치가 장착된 토사운반선(15)에 선적하여, 상기 토사운반선(15)을 매립지(10) 근처로 이동시켜 외부의 펌프준설선(13)에 접안시키고, 연결관(7)을 펌프준설선(13)에 연결한다.
다음으로 해수흡입조절밸브(4)를 개방하여 해수가 해수흡입구(3')를 통하여 메인흡입파이프(3)로 흡입되어 배출단(3'')으로 배출되도록 한 상태에서, 선수측부터 해수분사노즐(8)과 함께 토사흡입조절밸브(6)를 먼저 개방하여 선수측부터 토사흡입파이프(5)를 통하여 메인흡입파이프(3)로 토사를 흡입하여 배출하게 된다.
이 때, 선수측부터 토사가 배출됨에 따라 도 7에 도시된 바와 같이 토사운반선의 선수측이 들리게 되므로 토사운반선이 적정한 종경사(트림)를 유지하게 되어 선미측으로 가면서 차례대로 토사(18)를 배출할 수 있게 된다.
즉 차례대로 먼저 개방된 토사흡입조절밸브(6)를 폐쇄하면서 선미측 토사흡입조절밸브(6)를 개방하여 토사가 선수측에서부터 배출되도록 하여 결국 마지막에는 선미측에서 토사가 모두 배출되도록 한다.
이 때 토사의 흡입은 토사운반선의 선창 하부 상면에서 진행되기 때문에 흡입수두가 낮아지고 상대적으로 배출 수두가 높아지게 되어 도 8에 도시된 바와 같이 본 발명에 따른 준설토사운반장치가 장착된 토사운반선을 이용한 토사배출방법(20)은 같은 용량의 펌프를 사용하더라도 종래의 토사배출방식(19)보다 더욱 멀리 토사를 이송, 배출시킬 수 있게 되므로, 공사기간을 단축할 수 있고 비용을 절감할 수 있다.First, the dredged seabed is dredged using the dredger in the designated dredging water, and the dredged soil is shipped to the soil carrier 15 equipped with the dredged soil carrier according to the present invention, and the soil carrier 15 is reclaimed from the landfill 10. It is moved near to the berthing to the external pump dredger 13, and connects the connecting pipe (7) to the pump dredger (13).
Next, seawater injection is performed from the bow side while opening the seawater suction control valve 4 so that the seawater is sucked into the main suction pipe 3 through the seawater suction port 3 'and discharged to the discharge end 3''. The earth and sand suction control valve 6 together with the nozzle 8 is first opened to suck and discharge the earth and sand into the main suction pipe 3 through the earth and sand suction pipe 5 from the bow side.
At this time, as the soil is discharged from the bow side, the bow side of the earth and sand carrier is lifted as shown in FIG. 7, so that the earth and sand carrier maintains an appropriate longitudinal slope (trim), and discharges the sand and sand 18 in turn while going to the stern side. You can do it.
That is, in order to close the earth-suction suction control valve 6, which is opened first, the stern-side earth-suction suction control valve 6 is opened so that the earth and sand are discharged from the bow side.
At this time, the suction of the earth and sand is carried out from the upper surface of the lower bottom of the earth and sand carriers, so that the suction head is lowered and the discharge head is relatively high, as shown in Figure 8 using a dredged soil carrier equipped with a dredged soil carrier according to the present invention The earth and sand discharge method 20 can transport and discharge the earth and sand farther than the conventional earth and sand discharge method 19 even if the pump of the same capacity, it is possible to shorten the construction period and reduce the cost.
