Abstract

Install a water bag(1) and an air valve(2) at the top of the sack(5). Tie it with a chain(4) at the bottom to prevent the twisting of the sack. Each sack(5) is connected with a link(3). An anchor(7) sunk at the bottom and a link is connected with a rope(6) so that it may stay floating at a fixed place. The sack is made of fabrics with good flexibility such as PVC or PU instead of the strong material so that the sack is not broken even in the high waves.

본 발명은 해수의 유통이 가능하며 폭풍우와 같은 악천후시에도 견딜 수 있을 뿐만 아니라 설치 해역의 조건에 따라 설계 변경이 가능한 유연막 백(Bag)구조 부유식 방파제에 관한 것이다.The present invention relates to a flexible membrane bag structure floating breakwater that can be distributed in seawater and can withstand bad weather conditions such as storms, and can be changed in design according to the conditions of the installation sea area.

항만내 계류된 선박과 연안양식장을 보호하기 위하여 해안으로 입사하는 파를 차단하는 것에 목적이 있는 종래의 일반적인 방파제에 있어서는 대개 돌이나 콘크리트를 사용한 고정식 방파제이므로 수면에 발생하는 파도 뿐만아니라 수면 하부의 흐름을 완전히 차단하므로 해수의 순환이 자유롭게 이루어지지 않아 해양 생태계의 파괴는 물론 연안내 물의 오염을 가속시키고 있다.In conventional general breakwaters aimed at blocking the waves entering the shore to protect the mooring vessels and coastal farms in the harbor, they are usually fixed breakwaters using stones or concrete, so they are not only waves generated on the surface of the water, As it completely blocks the ocean, the circulation of seawater is not free, which not only destroys the marine ecosystem but also accelerates the pollution of water in the coast.

이와같은 이유로 물의 흐름을 허용하는 부유식 방파제 예를 들어 일본공개실용소 50-140233호는 고무벨트에 고정식 고분자 재료의 원통부재로서 1점 체인계류로서 설치한 것이 있으나 이는 부체내의 수위조절이 불가하고 동 50-140235호는 폐타이어에 합성수지를 충진하고 다점 체인계류로서 설치하였으나 이는 부력조절이 불가하며 동 49-69735호는 부체에 관체플로트를 삽입하고 다점와이어 계류로서 설치하였으나 이는 가압공기 사용으로 부력을 조절하나 조절량이 소량인 결점이 있었다.For this reason, floating breakwaters that allow the flow of water, for example, JP 50-140233, are installed on the rubber belt as a cylindrical member of fixed polymer material as a one-point chain mooring, but this is impossible to control the water level in the float. No. 50-140235 filled synthetic tires with waste tires and installed them as multi-point chain mooring, but it was impossible to adjust buoyancy. No. 49-69735 installed pipe floats in the floating body and installed them as multi-point wire mooring. There was a flaw that regulated buoyancy but a small amount of control.

본 발명은 이와같은 종래의 문제점을 개선하여 해수의 순환이 가능하며 폭풍우와 같은 악천후시에도 잘 견딜수 있는 유연막 백구조 부유식 방파제를 제공하는 것에 그 목적이 있다.The present invention aims to provide a flexible membrane bag structure floating breakwater that can improve circulation of seawater and to withstand even in bad weather conditions such as storms.

상기와 같은 목적을 달성하기 위하여 유연막 백구조 부유식 방파제는 파 에너지를 흡수하여(백의 운동으로 열에너지로 바뀌나 이는 본 발명의 요지가 아님으로 그 상세한 설명은 생략함) 태풍과 같은 악천후시 손상을 적게 받고, 적절한 홀수(draft)를 갖도록 유연성이 좋은 PU(Polyurethane)나 PVC천으로 만든 섹(sack)내에 물을 채운 구조로 형성되며 섹을 일정한 형태로 유지하기 위하여 공기를 유입한 후 물을 채우는 원리를 이용하며 물 주입시 섹 내에 일정한 압력 이상이 되면 자동적으로 공기를 배출시켜 압력을 일정하게 유지시키는 압력공기밸브 장치를 구비하고 파도나 흐름에 의하여 섹이 뒤틀리는 것을 방지하기 위하여 섹 밑에 체인을 설치하여 안정된 자세를 유지하도록 구성되는 것을 특징으로 한다.In order to achieve the above object, the flexible membrane bag structure floating breakwater absorbs wave energy (which is converted into thermal energy by the movement of the bag, which is not the gist of the present invention, and thus the detailed description thereof is omitted). It is formed in a structure filled with water in a sacks made of PU (Polyurethane) or PVC cloth with good flexibility to have proper odds, and fills water after inflowing air to maintain a constant shape. It is equipped with a pressure air valve device that automatically discharges the air and maintains a constant pressure when the water pressure is over a certain pressure in the section during water injection, and installs a chain under the section to prevent the section from twisting due to waves or flow Characterized in that it is configured to maintain a stable posture.

이와같이 구성되어진 본 발명은 첨부 도면에 연계하여 상세히 설명하면 다음과 같다.The present invention configured as described above will be described in detail with reference to the accompanying drawings.

제1도는 본 발명의 유연막 백구조 방파제의 개략도로써, 섹(sack)(5)의 상단에 물주머니(1)와 압력공기 밸브(2)가 형성되며 섹이 뒤틀어지는 것을 방지하도록 섹(5)의 하부에 체인(4)을 결합하여 각각의 섹(5)은 샤클(3)에 의해 연결되어지며 고정된 장소에서 부유할 수 있도록 해저에 침수된 앵커(7)와 샤클(3)이 로프(6)로 연결되어 지도록 구성되어지며, 높은 파도에서도 견딜수 있도록 강체 대신에 유연성이 좋은 PVC, PU(Polyurethane)와 같은 천으로 만든 섹(sack)을 사용하였다.1 is a schematic view of the flexible membrane bag structure breakwater of the present invention, wherein the water bag 1 and the pressure air valve 2 are formed on the top of the sack 5 and the sack 5 is prevented from twisting. Each section 5 is coupled to the lower part of the chain (4) is connected by the shackle (3) and the anchor (7) and the shackle (3) submerged in the seabed to float in a fixed place is rope ( 6) Sack made of cloth such as PVC and PU (Polyurethane) with good flexibility was used instead of the rigid body to withstand high waves.

방파제의 형태를 유지하고 어느정도 수면밑으로 가라 앉히기 위하여 섹 내에 물을 주입하였다.Water was injected into the sections to maintain the shape of the breakwater and to subside to some extent.

따라서 수면 밑으로 잠기는 깊이는 전체 섹 용량에 대한 투입된 물의 양으로 결정된다.The depth of submersion is therefore determined by the amount of water injected over the total section volume.

그러나 물만을 주입하면 물의 무게에 의하여 양쪽으로 쳐지므로 원하는 형태의 구조물을 만들 수 없다.However, if only water is injected, it is struck on both sides by the weight of the water, so that the structure of the desired shape cannot be made.

이를 해결하기 위하여 먼저 공기를 섹 내에 불어넣어 원하는 구조물을 만든 뒤 물을 주입하여야 한다.In order to solve this problem, air must be blown into the sections to make the desired structure and water must be injected.

이때 물이 주입되면서 섹 내의 압력은 상승한다.As water is injected, the pressure in the section rises.

섹 내의 압력을 일정하게 유지하기 위하여 섹 상단에 압력밸브를 설치한다.Install a pressure valve at the top of the section to maintain a constant pressure in the section.

물의 주입으로 상승된 압력은 일정한 값이상이 되면 밸브를 통하여 자동적으로 공기가 밖으로 배출된다.When the pressure raised by the injection of water is above a certain value, the air is automatically discharged through the valve.

이렇게 제작된 섹을 여러개 연결하면 방파제가 되며 방파제의 위치 유지를 위하여 중간 여러점을 앵커로 계류시킨다.Connecting several sections thus made breakwater and mooring several points in the middle to maintain the position of the breakwater.

또한 공기와 물의 비율을 적절히 조절하면 손쉽게 방파제의 흘수를 조정할 수 있으므로 설치된 해역의 파의 주기와 파고를 미리 파악하여 파 차단효과가 우수한 방파제를 설계할 수 있다.In addition, if the ratio of air and water is properly adjusted, the draft of the breakwater can be easily adjusted, so the breakwater and the wave height of the installed sea area can be grasped in advance to design a breakwater having excellent wave blocking effect.

이와 같이 구성되어진 본 발명은 종래의 돌이나 콘크리트를 사용한 고정식 방파제가 해수가 순환을 차단의 원인으로 발생되는 해양 생태계의 파괴와 연안내의 부영양화로 인한 오염문제를 해결할 수 있을 뿐만 아니라 기존의 물의 흐름을 허용하는 부유식 방파제 악천후시 부유식 방파제를 계류하는 로프가 끊어지거나 방파제가 손상을 입는 등의 문제점을 해결할 수 있어 경제적인 측면에서도 그 효과가 기대되는 것이다.The present invention constituted as described above can solve the problem of pollution due to the destruction of marine ecosystem and the eutrophication in the coast where fixed breakwater using conventional stone or concrete can cause seawater to block circulation. Floating breakwater to allow the problem can be solved in the economic aspects, such as to solve the problems such as broken rope breakage or damage breakwater mooring floating breakwater in bad weather.
