최근에는 해저도시개발이나 해저터널 등과 같은 해저면의 개발이 활발해지고 있다. 해저면을 개발하기 위해서는 우선적으로 해저지층 표면 퇴적토의 경계면에 일정한 두께로 모래나 쇄석과 같은 골재를 투하하여 포설하는 작업이 선행되어야 한다.In recent years, the development of seabeds such as undersea urban development and undersea tunnels has become more active. In order to develop the sea bottom, the work of laying and laying aggregates such as sand or crushed stone at a predetermined thickness on the interface of the seabed surface sediment should be preceded.

상기와 같이 수중에 골재를 투하하기 위해 최근에는 골재를 적재한 바지선에 호퍼를 설치하고, 상기 호퍼의 수직하방으로 해저면에 골재가 투입되는 트리미관을 설치하여 중장비를 통해 골재를 투하하면서 포설작업을 하는 골재 투하장치가 사용되고 있다.In order to drop the aggregate in the water as above, the hopper is recently installed on the barge on which the aggregate is loaded, and the installation work is carried out while dropping the aggregate through heavy equipment by installing a trim tube in which the aggregate is injected at the bottom of the hopper vertically. Aggregate dropping device is used.

그러나, 상기와 같은 골재 투하장치는, 바지선에 적재된 골재를 해저면에 균일하게 투하하지 못할 뿐만 아니라 해저면에 투입된 골재를 편평하게 고르기 위해서 별도의 잠수인원을 동원하여 수중작업을 해야하므로 작업공정이 까다로울 뿐만 아니라 인건비가 상승하여 비경제적인 문제점이 있었다.However, the aggregate discharging device as described above, not only do not drop the aggregate loaded on the barge uniformly on the sea floor, but also requires a separate submerged personnel to evenly flatten the aggregate put on the sea floor to work underwater process Not only is this tricky, but labor costs have risen, causing uneconomic problems.

이와 같이 구성되는 본 발명의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the present invention configured as described above are as follows.

먼저, 도 1에 도시된 바와 같이, 바지선(10)에 골재고르기수단(100)을 적재 한 상태에서, 바지선(10)에 마련된 중장비와 골재고르기부(110)의 인양고리(111a)에 로프(L)로 연결고정한다.First, as shown in FIG. 1, in the state in which the aggregate leveling means 100 is loaded on the barge 10, the rope (a) on the lifting ring 111a of the heavy equipment and the aggregate leveling unit 110 provided on the barge 10. Secure the connection with L).

상기 로프(L)를 골재고르기수단(100)에 연결한 상태에서, 중장비(E)를 작동하여 골재고르기수단(100)을 상부로 들어올린 후, 작업위치의 해저면으로 투하하여 안착시킨다.In the state in which the rope (L) is connected to the aggregate leveling means (100), by operating the heavy equipment (E) to lift the aggregate leveling means (100) to the top, dropping to the bottom of the working position to be seated.

상기와 같이 해저면에 안착된 골재고르기수단(100)을 작동하기 위해서는, 먼저, 이동부(120)를 제어해야 하는데, 상기 이동부(120)는 바지선(10)에 마련된 제어부에서 제어하게 된다.In order to operate the aggregate leveling means 100 seated on the bottom of the sea as described above, first, the moving unit 120 must be controlled, and the moving unit 120 is controlled by a control unit provided on the barge 10.

상기 제어부는 GPS측량시스템 및 USBL심도계를 이용하여 해저의 정확한 좌표를 설정할 수 있고, 골재고르기수단(100)과 유압호스로 연결되어 있다.The control unit may set the exact coordinates of the seabed using a GPS surveying system and a USBL depth meter, and is connected to the aggregate leveling means 100 and a hydraulic hose.

상기 제어부를 작업자가 제어하게 되면, 도 2 또는 도 4에 도시된 바와 같이, 제어부에 의해 유압감속모터(124)가 회전하게 되고, 유압감속모터(124)에 형성된 피니언(124a)은 래크(123)와 치합되어 회전함과 동시에 이동안내편(122)이 안내레일(121)에 안내되어 좌.우로 이동하게 되며, 고르기부재(112)가 전방에 투하된 골재를 좌.우 이동하면서 편평하게 고르기 작업을 수행하는 것이다.When the operator controls the controller, as illustrated in FIG. 2 or 4, the hydraulic deceleration motor 124 is rotated by the controller, and the pinion 124a formed in the hydraulic deceleration motor 124 is a rack 123. At the same time as the rotation and the rotation guide piece 122 is guided by the guide rail 121 is moved to the left and right, the picking member 112 to move the aggregate dropped in front of the left and right while picking a flat. To do the job.

또한, 상기 고르기부재(112)에 인접해 있는 골재의 고르기작업을 완료하면, 도 5에 도시된 바와 같이, 제어부에서 전방이동부재(132)의 유압실린더(132a)를 조절하여 이동궤도(132c)를 하강시킨다.In addition, when the picking operation of the aggregate adjacent to the selecting member 112 is completed, as shown in FIG. 5, the control unit adjusts the hydraulic cylinder 132a of the front moving member 132 to move the trajectory 132c. Descend.

이때, 전방이동부재(132)의 이동궤도(132c)가 하강한 높이만큼 골재고르기부(110)의 높이가 상승하게 된다.At this time, the height of the aggregate picker 110 is increased by the height of the moving trajectory 132c of the front moving member 132.

상기와 같이 전방이동부재(132)를 하강시킨 상태에서, 표면조절부재(131)를 제어부에서 조절하게 되면 유압실린더(131a)는 표면조절판(131b)을 상부로 상승시켜 해저면에서 이격시키게 된다.When the front moving member 132 is lowered as described above, when the surface control member 131 is adjusted by the control unit, the hydraulic cylinder 131a raises the surface control plate 131b to the top to be spaced apart from the sea bottom.

한편, 상기 전방이동부재(132)의 이동궤도(132c)는 제어부의 제어에 따라 전방으로 이동하게 됨과 동시에 골재고르기부(110)를 전방으로 이동시키게 된다.On the other hand, the movement trajectory 132c of the front moving member 132 is moved forward and under the control of the controller at the same time to move the aggregate picker 110 forward.

상기와 같이 골재고르기부(110)가 전방으로 이동된 상태에서, 표면조절부재(131)의 표면조절판(131b)을 해저면으로 하강시키게 되면 골재고르기부(110)가 해저면에 밀착되고, 이때, 전방이동부재(132)의 이동궤도(132c)를 상부로 상승시키게 되며, 골재고르기부(110)는 이동부(120)의 작동에 의해 좌.우로 이동하면서 해저면에 투하된 골재의 고르기작업을 반복적으로 수행하는 것이다.As described above, when the aggregate leveling unit 110 is moved forward, when the surface control plate 131b of the surface adjusting member 131 is lowered to the bottom, the aggregate leveling unit 110 is in close contact with the bottom. , The movement trajectory 132c of the front moving member 132 is raised to the top, and the aggregate picking unit 110 moves to the left and right by the operation of the moving unit 120 while selecting the aggregate dropped on the sea floor. It is done repeatedly.

상기 골재고르기수단(100)은 사석, 모래와 같은 골재 이외에도 해저면에 불규칙하게 형성된 갯벌지역을 편평하게 고를 때도 상기와 동일한 방법으로 작업을 수행하면 되는 것이다.The aggregate leveling means 100 is to perform the operation in the same manner as above even when selecting flat tidal flat areas irregularly formed on the sea bottom in addition to aggregates such as sand stone, sand.

또한, 상기 골재고르기수단(100)은 바지선(10)에서 해저면으로 투하하여 고르기작업을 수행한다고 설명하였으나 이에 한정하는 것은 아니며, 바지선 이외에도 잭업-바지선에서도 사용가능함을 밝혀둔다.In addition, the aggregate picking means 100 is described as dropping to the bottom of the barge to perform the selection operation, but is not limited to this, it turns out that it can be used in the jack-up pants in addition to the barge.

이상에서 상술한 본 발명은, 유압감속모터의 구동에 의해 고르기부재를 좌.우로 이동시키므로 트리미관에서 불규칙하게 투하된 골재의 균일한 고르기작업이 가능하므로 작업효율성이 향상됨과 아울러 정밀시공이 가능한 이점이 있다.In the present invention described above, since the evening member is moved left and right by driving the hydraulic deceleration motor, it is possible to uniformly uniformly aggregate the aggregates dropped in the trim tube, thereby improving the work efficiency and enabling the precise construction. There is this.

또한, 본 발명은, 전방이동부재의 이동궤도가 골재고르기부를 전방으로 이동시키면서 골재의 고르기작업을 반복적으로 수행하므로 잠수인력에 대한 인건비를 절감할 수 있어 경제적인 이점이 있는 것이다.In addition, the present invention, it is possible to reduce the labor cost for the diving personnel because the moving trajectory of the front moving member to repeatedly move the aggregate leveling portion to the front, there is an economic advantage.
