To measure the three-point reference flatness with a total station, install three auxiliary reference points on the wall of the floating dock at the same level as this virtual plane, and place the waterline marking on the total station. The method relates to the method of marking the ship's waterline in a floating dock which performs the waterline marking of the ship after performing the three-point flatness measurement again at three points installed on the wall.

종래의 흘수선 마킹은 드라이 도크나 지상 등 블록이나 선박이 움직이지 않은 상태에서 흘수선 마킹을 실시하고 있다.Conventional water line marking is a water line marking is carried out in the state that the block and the vessel, such as dry dock, ground or the like is not moved.

그러나, 종래기술은 플로팅 도크에서 제작되는 선박은 플로팅 도크와 선박이 움직임을 계속함에 따라 기존의 방법으로는 선박의 흘수선을 마킹할 수 없으며, 블록이나 선박을 드라이 도크나 지상으로 이동시켜야 하기 때문에 시간이 오래 걸리고, 작업이 복잡해지는 문제점이 있다.However, in the prior art, a ship manufactured in a floating dock cannot mark the waterline of the ship by the conventional method as the floating dock and the ship continue to move, and since a block or a ship must be moved to a dry dock or the ground, This takes a long time, and the work is complicated.

상술한 바와 같은 문제점을 해결하기 위하여, 본 발명은 플로팅 도크에서 흘수선 마킹은 선박의 바닥면에 세 점 기준점을 설정하고, 이 기준점으로 편평도를 측정하여 설정된 편평도와 같은 레벨 기준점 세 점을 플로팅 벽면에 부착하고, 토털스테이션(Total station)을 흘수선 마킹 위치에 설치하여, 플로팅 도크 벽면에 부착된 세 점으로 편평도 측정을 다시 실시한 후, 흘수선 마킹을 실시하는 플로팅 도크에서 선박의 흘수선 마킹 방법을 제공하는데 목적이 있다.In order to solve the problems as described above, the present invention is to set the three-point reference point on the bottom surface of the ship's waterline marking in the floating dock, by measuring the flatness with this reference point three level reference points such as the set flatness on the floating wall surface To provide a method of marking the ship's waterline in a floating dock where the total station is installed at the waterline marking position, the flatness measurement is again performed at the three points attached to the floating dock wall, and the waterline marking is performed. There is this.

이하, 도면을 참고로 플로팅 도크에서 선박의 흘수선 마킹 방법을 설명하면 다음과 같다.Hereinafter, a method of marking a ship's waterline in a floating dock with reference to the drawings as follows.

도 1은 본 발명의 플로팅 도크에서 선박의 흘수선 마킹 공정도를 나타내는데, 도 2와 같이 플로팅 도크(20)에 흘수선 마킹을 위해 선박(10)이 구비된다.1 shows a process line marking process of a vessel in a floating dock of the present invention, as shown in Figure 2 is provided with a vessel 10 for the waterline marking on the floating dock 20.

상기 플로팅 도크(20) 내부에 구비되는 선박(10)의 편평한 밑바닥에 자석을 사용하여 테이프타켓(30) 3개를 도 3과 같이 부착하고(S10 단계), 도 4와 같이 토털스테이션(40)을 사용하여 테이프타켓(30)의 세 점(B1, B2, B3)을 기준으로 편평도를 측정하는데, 각 기준점(B1, B2, B3)은 편평도 측정값이 “0”이 되도록 동일한 높이(L)로 설치되고(S20 단계), 상기 플로팅 도크(20) 벽면에는 세 점(B1, B2, B3)과 동일한 편평도의 높이로 보조타켓 세 점(W1, W2, W3)을 설치한다(S30 단계).Attach three tape targets 30 to the flat bottom of the vessel 10 provided in the floating dock 20 using a magnet as shown in Figure 3 (step S10), the total station 40 as shown in FIG. Flatness is measured based on the three points (B1, B2, B3) of the tape target 30, and each reference point (B1, B2, B3) has the same height (L) so that the flatness measurement value is "0". It is installed (step S20), the floating dock 20 is installed on the wall surface of the auxiliary target three points (W1, W2, W3) at the same height as the three points (B1, B2, B3) (step S30).

도 5(a)와 5(b)와 같이 상기 보조점 세 점(W1, W2, W3)의 타켓을 기준레벨과 같은 “0”이 되도록 높이 L만큼 수직 이동하고(S40 단계), 상기 토털스테이션(40)을 흘수선 마킹이 가능한 장소로 이동하여 설치하고(S50 단계), 상기 플로팅 도크(20) 벽면에 설치되어 수직 이동된 보조점 세 점(W1, W2, W3)을 기준으로 다시 편평도를 측정하는데, 상기 토털스테이션(40)을 흘수선 마킹 지점에 설치하여 기준점 세 점(B1, B2, B3)을 측정하면 보조점이 불필요할 수도 있으나, 선박(10) 밑에 설치된 반목으로 선박(10) 밑바닥에 설치된 기준점 세 점(B1, B2, B3)을 측정할 수 없으므로 보조점 세 점(W1, W2, W3)을 흘수선 마킹 지점에서 보이는 곳에 설치하게 된다(S60 단계).As shown in FIGS. 5A and 5B, the targets of the three auxiliary points W1, W2, and W3 are vertically moved by height L so as to be “0” equal to the reference level (step S40), and the total station 40 is moved to a place where waterline marking is possible (step S50), and the flatness is measured again based on three auxiliary points (W1, W2, and W3) vertically moved by being installed on the wall of the floating dock 20. However, if the total station 40 is installed at the waterline marking point to measure the three reference points (B1, B2, B3), the auxiliary point may not be necessary, but is installed on the bottom of the vessel 10 by the timber installed under the vessel 10. Since three reference points (B1, B2, B3) cannot be measured, three auxiliary points (W1, W2, W3) are installed where they are visible from the waterline marking point (step S60).

상기 보조점 세 점(W1, W2, W3)의 편평도 측정 후, 시트타켓(50)을 선박(10)의 흘수선 마킹 부위에 빛을 반사시키도록 부착하고, 플로팅 도크(20) 벽면에 부착된 보조점 세 점(W1, W2, W3)을 기준으로 흘수선 높이를 마킹하게 된다(S70 단계).After measuring the flatness of the three auxiliary points (W1, W2, W3), the seat target 50 is attached to reflect the light on the waterline marking portion of the vessel 10, and the auxiliary attached to the wall of the floating dock 20 Marking the draft line height based on the three points (W1, W2, W3) (step S70).

또한, 상기 보조점 세 점(W1, W2, W3)을 기준으로 흘수선 높이를 마킹 중에 영점 기준을 확인하면서 작업을 진행하게 되는데, 상기 영점 기준은 흘수선 측정 중에 보조점 세 점(W1, W2, W3)의 높이 “0”을 주기적으로 확인하게 된다.In addition, while the water line height is marked based on the three auxiliary points (W1, W2, W3), the work is performed while checking the zero point. The zero point reference is the three auxiliary points (W1, W2, W3) during the waterline measurement. The height of 0) is checked periodically.

본 발명은 상술한 특징의 바람직한 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the preferred embodiments of the above-described features, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention as claimed in the claims. Of course, such changes will fall within the scope of the claims.

상기한 바와 같이, 본 발명은 플로팅 도크에서 흘수선 마킹이 가능함에 따라 건조 선박의 안벽공기 단축과 건조 척수가 증대되는 효과가 있다.As described above, the present invention has the effect of shortening the sea wall air and drying spinal cord of the dry ship as it is possible to mark the waterline in the floating dock.
