The present invention relates to a solely floating type towing resistance reducing device attached to a front surface of a concrete structure (11) transported by sea. The solely floating type towing resistance reducing device for marine transportation of a concrete structure, comprises: a front plate (110) which maintains a plane to be aligned with the front surface of the concrete structure (11), and covers a front surface part of the concrete structure (11) from a lower part of the concrete structure (11) to a certain height; a vertical curved surface part (120) extended from both left and right sides of the front plate (110) rearward in a curved surface form to head for both left and right end parts of the front surface of the concrete structure (11); a lower curved surface part (130) extended from a bottom part of the front plate (110) rearward in a curved surface form to head for a bottom part of the front surface of the concrete structure (11); and a rear plate (140) which is coupled by being come in contact with end parts of the vertical curved surface part (120) and the lower curved surface part (130), is directly come in contact with the front surface part of the concrete structure (11), and forms a pocket whose upper part is only opened along with the front plate (110), the vertical curved surface part (120), and the lower curved surface (130), wherein the solely floating type towing resistance reducing device is tightly fixed to the front surface part of the concrete structure to be detachable by an anchor bolt that penetrates the rear plate (140).

    본 발명은 해상 운송되는 콘크리트 구조물(11)의 전면에 부착되는 단독 부유식 예인 저항 저감 장치에 관한 것으로서, 콘크리트 구조물(11)의 전면과 나란하게 평면을 유지하면서 콘크리트 구조물(11)의 하부에서 일정 높이까지 콘크리트 구조물(11)의 전면부를 덮는 전방플레이트(110); 상기 전방플레이트(110)의 좌우 양측에서 곡면 형태로 후방으로 연장되어 콘크리트 구조물(11)의 전면부 좌우 양측 단부를 향하는 수직곡면부(120); 상기 전방플레이트(110)의 하단부에서 곡면 형태로 후방으로 연장되어 콘크리트 구조물(11)의 전면부 하단부를 향하는 하부곡면부(130); 및, 상기 수직곡면부(120)와 상기 하부곡면부(130)의 단부와 맞닿아 결합되며 콘크리트 구조물(11)의 전면부에 직접 밀착되고, 상기 전방플레이트(110), 상기 수직곡면부(120) 및 상기 하부곡면부(130)와 함께 상부만 개방된 포켓을 형성하는 후방플레이트(140);를 포함하여 구성되며, 상기 후방플레이트(140)를 관통하는 앵커볼트에 의하여 콘크리트 구조물의 전면부에 탈부착식으로 밀착 고정되는 것을 특징으로 한다.
