본 발명에 따른 수중 준설토 운반 및 처리방법은 기본적으로 준설위치를 선정하는 준설위치선정단계(S100)와, 준설위치선정단계(S100)에서 선정된 위치로부터 준설토를 수집하는 준설토수집단계(S200)와, 준설토수집단계(S200)를 통해 수집된 준설토를 수중 외부로 유도하는 준설토유도단계(S300)와, 준설토유도단계(S300)를 통해 유도된 준설토(200)를 소정방향으로 분기시키는 준설토분기단계(S400)와, 준설토분기단계(S400)를 통해 안내된 준설토(200)를 또 다른 준설선(100)에 공급하여 배출시키거나 매립지(예로써, 연안 준설토를 새만금 매립지)에 배출하는 준설토배출단계(S500)로 구성된다.Underwater dredged soil transport and treatment method according to the present invention is basically the dredging position selection step (S100) to select the dredging position, and dredging soil collection step (S200) to collect the dredged soil from the position selected in the dredging position selection step (S100) and , Dredging soil induction step (S300) to guide the dredged soil collected through the dredged soil collection step (S200), and dredging soil branching step to branch the dredged soil (200) induced through the dredged soil induction step (S300) in a predetermined direction ( S400) and the dredged soil 200 guided through the dredged soil branch stage (S400) is supplied to another dredger 100 or discharged or dredged soil discharge step (S500) to discharge the dredged soil to the landfill (for example, Saemangeum landfill) (S500) It is composed of

상기 준설위치선정단계(S100)는 해상과 같은 수상에 준설작업을 위해 배치되는 복수개의 준설선(100)을 통해 그 일측에 설치된 준설파이프(110)를 사용하여 수중 저부의 토사를 준설하기 이전에 행해지는 단계로, 준설선(100)에 설치된 수심측량기(120)와 이로부터 전송되는 신호를 수신하여 준설위치를 선정해 알려주는 통제 실(300)을 통해 이루어진다. 이러한 수심측량기(120)는 초음파 임펄스를 발사하여 초음파가 배에서 해저까지 왕복하는 시간으로 깊이를 측정하는 것으로, 초음파의 전달속도가 바닷물의 온도와 염분, 수압 등에 따라 달라지므로 수심에 대한 바닷물의 물리적 특성 측정값을 이용하여 관측값을 수정해야 하며 일반적으로는 10∼200㎑ 정도의 주파수를 사용하는데, 주파수가 낮으면 깊은 곳까지 측정할 수 있는 반면 정밀도는 낮아지고 주파수가 높으면 정밀도는 향상되지만 깊은 수심까지 측정이 불가능해지므로, 보통은 정밀한 측정을 위해 200㎑ 가량의 주파수를 사용한다. 이러한 수심측량기(120)로는 기존의 음향측심기와 달리 음파의 송수신 범위 안에서 바다 밑 횡단면 전체를 동시에 측정할 수 있는 다중빔 음향측심기가 이용될 수 있고, 이 장비를 통해 배가 이동하면서 발사되는 다중음향신호 다시 수신하여 수심과 그 저부의 지형을 동시에 관측 및 기록하여 그러한 데이터를 통제실(300)로 무선 송신하고 이를 통제실(300)에서 분석하여 준설작업 위치를 각각의 준설선(100)에 무선으로 통보하게 된다.The dredging position selection step (S100) is carried out before dredging the sediment of the bottom of the water using the dredging pipe 110 installed on one side through a plurality of dredger 100 is arranged for dredging work in the water, such as sea. In the step, the depth gauge 120 installed in the dredger 100 and receives a signal transmitted from it is made through the control room 300 to select and inform the dredging position. The depth gauge 120 measures the depth by firing the ultrasonic impulse to the time when the ultrasonic waves reciprocate from the ship to the seabed, and the physical velocity of the sea water for the water depth because the speed of the ultrasonic wave depends on the temperature, salinity, water pressure, etc. Observations should be corrected using characteristic measurements, and frequencies of around 10 to 200 kHz are typically used. A lower frequency can measure deeper, while a lower precision and a higher frequency improves precision but Measurements up to depth are not possible, so use a frequency of around 200 kHz for precise measurements. Unlike the conventional echo sounder, a multi-beam echo sounder capable of simultaneously measuring the entire cross-section of the sea in the transceiving range of the sound wave may be used as the echo sounder 120. Upon receiving again, the depth and the topography of the bottom are simultaneously observed and recorded to transmit such data wirelessly to the control room 300 and analyzed in the control room 300 to wirelessly notify each dredger 100 of the location of dredging work. .

In addition, by installing a plurality of buoyancy material 420 in the collection box 400 to reduce the pressure caused to transport the dredged soil 200 to the guide pipe 500 by placing the collection box 400 to the water surface or collecting box 400 Maintenance can be facilitated.

In addition, the guide pipe 500 may be used as a variable length plastic corrugated pipe as described above so as not to be greatly influenced by terrain such as hills.

상기 준설토분기단계(S400)는 준설토유도단계(S300)를 통해 유도된 준설토(200)를 제어밸브(610) 및 제2모터펌프(510-2)가 설치된 복수개의 분기파이프(600)를 사용하여 소정방향으로 분기시키는 단계로, 이러한 단계를 통해 운반될 준설토(200)의 양을 조절하여 또 다른 준설선(100)으로 공급하거나 매립지(예로써, 연안 준설토를 새만금 매립지)와 같은 장소로 공급할 수 있다.The dredge soil branch step (S400) is a dredged soil 200 guided through the dredged soil induction step (S300) using a plurality of branch pipes 600, the control valve 610 and the second motor pump (510-2) is installed. In the step of branching in a predetermined direction, it is possible to adjust the amount of dredged soil 200 to be transported through this step to supply to another dredger 100 or to a place such as a landfill (eg, coastal dredged soil to Saemangeum landfill). .

상기 준설토배출단계(S500)는 준설토분기단계(S400)를 통해 운반된 준설토(200)를 또 다른 준설선(100)으로 공급하여 배출하거나 제3모터펌프(510-3)가 설치된 배출파이프(700)로 공급하여 배출하기 위한 단계로, 수심측량기(120)가 설치된 준설선(100)으로부터 전송된 신호에 기초하여 통제실(300)에서 준설토(200)의 배출위치가 결정된 다음 준설토(200)가 그 위치에 배출되거나, 배출파이프(700)로 공급된 준설토(200)를 제3모터펌프(510-3)를 통해 매립지 등에 배출하게 된다. 이러한 배출파이프(700)의 일측에는 길이 가변적이고 좌우 회동가능한 주름관이 설치되어 있어, 준설토(200)의 배출 위치를 유동적으로 변경하는 것이 가능하다.
