Description

해저 케이블 보호덮개{Undersea cable protective cover}Undersea cable protective cover

본 발명은 해저에 설치되는 HVDC(High Voltage Direct Current) 해저 케이블을 외력으로부터 보호하는 보호덮개에 관한 것으로, 특히 해저 케이블 횡간 수도구간 내에서 대형선박의 닻(앵카) 또는 닻 끌림에 대응하여 해저에 설치된 해저 케이블을 보호하는 해저 케이블 보호덮개에 관한 것이다.The present invention relates to a protective cover for protecting a high voltage direct current (HVDC) submarine cable installed on the seabed from external forces, in particular in response to the anchor (anchor) or anchor drag of a large ship in the cross section of the submarine cable transverse to the seabed. A submarine cable protective cover for protecting an installed submarine cable.

육지와 섬 사이 또는 섬과 섬 사이에 전력을 공급하기 위해 해저에 설치되는 HVDC(고전압 직류 송전체계) 해저 케이블은 전력의 장거리 송전을 큰 손실 없이 수행하는 전력 송전체계이며, 이 같은 HVDC 해저 케이블은 현재 우리나라의 해남 - 제주 간에 설치되어 있다.HVDC submarine cables installed on the seabed to supply power between land and island or between islands and islands are power transmission systems that perform long-distance transmission of power without significant loss. It is currently installed between Haenam-Jeju in Korea.

건설당시 해저에 해저 케이블 설치시 이 해저 케이블을 보호하는 보호공법으로 케이블 포설 후 폭 2m의 콘크리트 매트리스(Concrete Mattress)로 덮어 보호하고 있으나, 이 해저 케이블 횡간 수도구간에서 대형선박의 닻(앵카) 투하시 또는 닻 끌림에 의하여 설치한 해저 케이블이 손상되는 문제점이 발생하였다.When the submarine cable is installed on the seabed at the time of construction, it is protected by a concrete mattress with a width of 2m after the cable is laid.However, the anchorage of the large ship is dropped in the water section of the submarine cable transverse. There was a problem of damage to the submarine cable installed by the sea or anchor drag.

이에 본 발명은 해저 케이블을 외부의 위험요소, 예를 들어 대형선박의 닻 투하 또는 닻 끌림, 쇠말목 등으로부터 안전하게 보호할 수 있는 해저 케이블 보호덮개를 제공함에 그 목적이 있다.Accordingly, an object of the present invention is to provide a submarine cable protective cover which can safely protect a submarine cable from external dangers, for example, anchor dropping or anchor drag of a large ship, a metal horse, and the like.

상기와 같은 목적을 달성하기 위한 본 발명은 해저 케이블의 기존 보호설비인 콘크리트 매트리스 상부에 사다리꼴 역채널 홈을 가진 철근 콘크리트 덮개를 연속적으로 연결 시공하여 해저에 설치된 해저 케이블을 외부 위험손상 요소로부터 보다 안전하게 보호할 수 있도록 되어 있다.In order to achieve the above object, the present invention constructs a reinforced concrete cover having a trapezoidal reverse channel groove on the concrete mattress, which is an existing protection facility of a submarine cable, to continuously connect the submarine cable installed on the seabed to be safe from external risk damage factors. It is intended to protect.

상기와 같이 본 발명에 따른 해저 케이블 보호덮개는 해저에 설치되는 해저 케이블을 대형 선박의 닻 투여시 발생되는 충격이나 닻 끌림 등에 대응하여 해저 케이블의 손상을 보호할 수 있으면서 구조가 단순하여 시공설비도 간편하게 이루어지는 효과를 지닌다.As described above, the submarine cable protection cover according to the present invention can protect the damage of the submarine cable in response to the impact or anchor drag generated when the submarine cable is installed in the anchor of a large ship, while the construction is simple. It has the effect of being simple.

이하, 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 해저 케이블 보호덮개를 도시한 것으로, 도 1에 도시된 동일한 해저 케이블 보호덮개가 길이방향으로 연속 조립된 상태를 도 2의 도면에서 평면도로 보여주고 있는데, 동일한 해저 케이블 보호덮개들이 길이 방향으로 해저케이블을 포설한 콘크리트 매트리스 위에서 연속적으로 조립됨은 물론이다.Figure 1 shows a submarine cable protective cover according to the present invention, the same submarine cable protective cover shown in Figure 1 is shown in a plan view in the Figure of Figure 2 is a continuous assembly in the longitudinal direction, the same submarine cable protection The covers are of course assembled continuously on concrete mattresses with submarine cables in the longitudinal direction.

본 발명은 도면에 도시된 바와 같이 사다리꼴 역채널홈(1)을 가진 철근 콘크리트 덮개(2)를 갖추되, 이 철근 콘크리트 덮개(2)의 선단부(2a)에는 이웃한 동일한 철근 콘크리트 덮개(2)의 후단부(2b)가 삽입 연결되는 안착홈(3)을 가진 연결 중첩소켓(4)이 형성되어 있다.The present invention is provided with a reinforced concrete cover (2) having a trapezoidal reverse channel groove (1) as shown in the drawing, the front end portion (2a) of the reinforced concrete cover (2) is adjacent to the same reinforced concrete cover (2) A connecting overlapping socket 4 having a seating groove 3 into which the rear end 2b of the plug is inserted is formed.

따라서 본 발명에 따른 해저 케이블 보호덮개가 해저 케이블을 1차로 보호하는 해저 케이블 보호용 콘크리트 매트리스(미도시) 상부에 설치 시공될 때, 상기 철근 콘크리트 덮개(2)의 연결 중첩소켓(4)에 맞추어 조립 연결되며, 상기 철근 콘크리트 덮개(2)의 선단부(2a)에 형성된 연결 중첩소켓(4)은 안쪽 내부에 안착홈(3)이 형성된 다단계 구조를 갖는다.Therefore, when the submarine cable protective cover according to the present invention is installed on the submarine cable protection concrete mattress (not shown) to protect the submarine cable primarily, assembled in accordance with the connecting overlapping socket (4) of the reinforced concrete cover (2) The connection overlapping socket 4 formed at the tip portion 2a of the reinforced concrete cover 2 has a multi-step structure in which a seating groove 3 is formed inside.

이들 보호덮개의 연결 조립시 원활한 조립이 이루어지기 위해서 상기 연결 중첩소켓(4)의 안착홈(3)에 철근 콘크리트 덮개(2)의 후단부(2b)가 끼워 안착될 수 있도록 이 철근 콘크리트 덮개(2)의 선단부(2a)에 형성된 연결 중첩소켓(4)은 철근 콘크리트 덮개(2)의 후단부(2b)보다 큰 홈으로 형성되어 있음은 물론이다.The reinforced concrete cover (2b) of the reinforced concrete cover (2) can be fitted into the seating groove (3) of the connecting overlapping socket (4) in order to achieve a smooth assembly when the protective cover is assembled The connecting overlapping socket 4 formed at the tip end 2a of 2) is, of course, formed of a groove larger than the rear end 2b of the reinforced concrete cover 2.

그리고 본 발명은 대형 선박에서 투여되는 닻이나 닻 끌림 등에 견딜 수 있는 강도와 충격량에 대응할 수 있도록 되어 있고, 해저에 설치된 콘크리트 매트리스에서 시공할 경우에는 크레인으로 견인 후(헤드앙카에 와이어 연결) 바다 속에 투여한 후 콘크리트 매트리스에서 각을 맞추어 끌어당겨서 철근 콘크리트 덮개(2)의 연결 중첩소켓(4)이 이웃하는 철근 콘크리트 덮개(2)의 후단부(2b)에 삽입되어 안착되는 시공방식으로 설치할 수 있다.In addition, the present invention is able to cope with the strength and the amount of impact that can withstand the anchor or anchor drag administered in a large vessel, and when to be installed in a concrete mattress installed on the seabed after towing with a crane (wire connection to the head anchor) in the sea After dosing, it can be installed in a construction method in which the connecting overlapping sockets 4 of the reinforced concrete cover 2 are inserted into the rear end 2b of the neighboring reinforced concrete cover 2 by being pulled at an angle from the concrete mattress. .

해저에서 시공상태는 도 2와 같이 연속으로 연결하여 설치하도록 되어 있다.The construction state in the seabed is to be installed in series connected as shown in FIG.

도 1은 본 발명에 따른 해저케이블 보호덮개의 사시도,1 is a perspective view of a submarine cable protective cover according to the present invention,

도 2는 본 발명을 연속하여 설치한 상태의 축소상태의 평면도이다.2 is a plan view of a reduced state in a state where the present invention is continuously installed.
