Description

해안침식 방지용 파압 및 해빈류 완화 시스템Wave pressure and beach flow relief system to prevent coastal erosion
본 발명은 파랑에 의해 해안의 모래가 침식되는 현상을 최소화함으로써 해안의 침식을 방지하고 해저사면의 경사를 완화하기 위한 파압 및 해빈류 완화 시스템에 관한 것이다.The present invention relates to a wave pressure and beach flow mitigation system for preventing the erosion of the shore by reducing the erosion of sand on the shore by the waves to reduce the slope of the seabed slope.
해안의 모래사장은 육지의 하천 및 해안사구 등으로부터 공급된 모래가 퇴적되어 생성되는데, 자연상태에서는 공급되는 모래가 해안에 퇴적되는 현상과 파랑에 의해 모래가 바다쪽으로 유실되는 현상이 균형을 이루어서 모래사장을 유지하게 된다.The coastal sandy beach is produced by the accumulation of sand supplied from onshore rivers and coastal dunes. In the natural state, sand is supplied to the beach and sand is lost to the sea due to blue. Maintain the president.
한편, 해안의 모래사장은 환경보존 측면에서 뿐만 아니라 각종 해양 레포트의 인기 등에 힘입어 관광자원으로서도 그 중요성이 부각되고 있으나, 하천정비사업으로 인하여 하천변이 매립되거나 콘크리트 제방으로 차단되고, 도시시설 건립에 따른 자연녹지 감소와 해안매립에 의한 해안사구 소멸 등의 이유로 바다로 유입되는 모래량이 급격히 감소됨으로써 해안의 모래사장이 감소되는 현상이 발생하고 있다. On the other hand, coastal sandy beaches are not only important for environmental preservation, but also for tourism resources due to the popularity of various marine reports.However, due to the river maintenance project, riversides are reclaimed or blocked by concrete embankments. Due to the decrease of natural green space and the disappearance of coastal sand dunes due to shore reclamation, the amount of sand flowing into the sea is drastically reduced, resulting in the reduction of sandy beaches on the coast.
따라서, 해안의 모래사장이 감소되는 현상을 방지하기 위한 노력이 다양하게 시도되고 있는데, 모래사장이 감소되는 현상을 방지하는 방법은, 인공구조물을 설치하여 파랑의 영향력을 차단하거나 감쇄시키는 이른바 강제쇄파방식과, 타지역의 모래를 운반해 와서 모래사장에 공급하는 인공양빈방식으로 대별될 수 있다.Therefore, various efforts have been made to prevent the reduction of sandy beaches. The method of preventing the reduction of sandy beaches is a so-called forced breaking wave that blocks or attenuates the influence of waves by installing artificial structures. It can be roughly classified into a method and an artificial empty method of transporting sand from other regions and supplying it to a sandy beach.
여기서, 강제쇄파방식은 다시 해안에서 바다쪽으로 떨어진 해저에 수중구조물을 설치하는 잠제방식과 해안에 근접하거나 해안선 안쪽에 구조물을 설치하는 호안방식으로 나누어진다.Here, the forced crushing method is divided into a submerged method for installing an underwater structure on the sea floor away from the coast and a coastal method for installing the structure close to the shore or inside the shoreline.
잠제방식에는 구조물의 형태에 따라 수면하에 구성되는 구조물 즉, 잠제(潛堤)를 이용하여 저파랑만을 차단하는 방식과, 수면위로 일정높이 만큼 돌출되는 구조물인 이안제를 이용하여 저파랑 및 고파랑을 모두 차단하는 방식으로 구분된다.In the submerged method, low blue and high blue are formed by using a structure that is constructed under the surface of the water according to the shape of the structure, that is, a method of blocking only low blue color by using the submerged material, and an ophthalmic agent which protrudes to a certain height above the water surface. All are separated by blocking.
호안방식은 해안 안쪽에 호안벽 등을 설치하여 파랑의 영향이 육지 측으로 미치는 것을 완전히 차단하는 것이다.The shore protection method is to install the shore walls inside the coast to completely block the impact of the waves to the land side.
한편, 이러한 종래기술에 있어서, 강제쇄파방식에 의한 경우에는 해안의 침식이 어느 정도 방지되기는 하지만, 구조물의 형태와 위치에 따라 해저세굴 및 해안선의 전진과 후퇴 등의 현상이 유발됨으로써 해안선의 변형을 초래하게 된다는 문제점이 발생하게 된다. On the other hand, in the prior art, although the rupture of the shore is prevented to some extent by the forced rupture method, depending on the shape and position of the structure, the phenomenon such as seabed scouring and the advancement and retreat of the shoreline is induced, thereby deforming the shoreline. The problem arises.
또한, 잠제, 이안제는 해류나 파랑에 의해 휩쓸리지 않을 정도의 견고함을 필요로 하기 때문에 이러한 조건을 만족하기 위하여 콘크리트 구조물로 이루어지며 구조적인 특성상 선박의 운행에 지장을 준다는 문제점이 발생하게 된다.In addition, the latent agent and langue agent need to be strong enough not to be swept away by currents or waves, so that it is made of a concrete structure to satisfy these conditions and causes a problem that the ship's operation is hampered due to its structural characteristics.
인공양빈방식은 모래채취 및 운반에 많은 비용이 소요될 뿐만 아니라, 모래의 유실을 막는 근본적인 대책이 아니기 때문에 이에 따르면 지속적으로 모래를 공급하여야 한다는 부담이 있다.The artificial farming method is not only expensive for collecting and transporting sand but also is not a fundamental measure to prevent the loss of sand.
본 발명은 상술한 바와 같은 종래기술의 문제를 해결하기 위한 것으로서, 해안으로 가해지는 파압 및 해빈류에 대하여 해저면이 침식되는 현상을 억제하고, 해빈류의 흐름을 완화시켜 해안의 모래가 유실되는 현상이 감소되도록 하는 파압 및 해빈류 완화 시스템의 제공을 목적으로 한다.The present invention is to solve the problems of the prior art as described above, to suppress the erosion of the sea bottom against the wave pressure and beaches applied to the shore, to reduce the flow of beaches to lose the sand of the shore It is an object of the present invention to provide a wave pressure and beach flow mitigation system to reduce the phenomenon.

It includes an expansion frame to form a plurality of filling spaces and fixing means for fixing the explosion frame.

여기서, 상기 방파프레임은 복수개 구비되어 일측 방파프레임은 해안에 근접한 위치에서 해저면으로 부터 노출되지 않게 매립설치되며, 타측 방파프레임은 상기 일측 방파프레임보다 바다측으로 이격된 위치에서 해저면으로부터 노출되게 설치될 수 있다.Here, a plurality of the break-proof frame is provided so that one side of the break-proof frame is installed to be buried not exposed from the sea bottom at a position close to the shore, the other side of the break frame is installed to be exposed from the sea bottom at a position spaced to the sea side than the one side of the break-proof frame Can be.
본 발명에 따른 파압 및 해빈류 완화 시스템에 의하면, 파랑의 영향력 즉 파압 및 해빈류가 약화됨으로써 해안에 근접한 해저면의 침식이 감소되고, 해안의 모래 유실이 억제되어 모래사장의 보존에 도움이 된다는 이점이 있다.According to the wave pressure and beach flow mitigation system according to the present invention, the influence of the wave, that is, the wave pressure and the beach wave is weakened, the erosion of the sea bottom near the shore is reduced, and the loss of sand on the coast is suppressed, which helps to preserve the sandy beach.

본 발명에 따른 파압 및 해빈류 완화 시스템은 도 2와 도 3에 나타난 것과 같이 다수개의 플레이트(12)가 서로 평행하게 중첩 배치되고 길이방향으로 일정한 간격을 두고 서로 인접된 것끼리 부분적으로 접합된 구조로서 측방향으로 확장되어 다수개의 충진공간(10a)을 형성하는 방파프레임(10)과, 상기 방파프레임(10)을 고정하는 고정수단을 포함하여 이루어진다.The wave pressure and beach flow relief system according to the present invention has a structure in which a plurality of plates 12 overlap each other in parallel to each other and partially adjacent to each other at regular intervals in the longitudinal direction as shown in FIGS. 2 and 3. As a side extends in the lateral direction forming a plurality of filling space (10a) and the frame comprises a fixing means for fixing the blast frame (10).
상기 고정수단은 상기 방파프레임(10)의 상단을 덮는 격자형의 고정틀(20)과, 상기 고정틀(20)과 엮이어서 고정앵커(32)에 의해 해저면에 고정되는 고정와이어(30)를 포함하여 이루어진다. The fixing means includes a grid-shaped fixing frame 20 covering the upper end of the breakwater frame 10, and the fixing wire 30 is woven with the fixing frame 20 to be fixed to the sea bottom by the fixing anchor 32. It is done by
본 발명에 따른 파압 및 해빈류 완화 시스템은 복수개의 방파프레임(10)이 배치되는 구성으로 이루어지는데, 일측 방파프레임(10)은 해안에 근접한 위치에 설치되어 해저면으로 부터 노출되지 않게 매립되며, 타측 방파프레임(10')은 상기 일측 방파프레임(10)보다 바다측으로 이격된 위치에서 해저면으로부터 노출되게 설치된다.(이후부터, 해안에 근접하여 설치된 방파프레임은 근안(近岸) 방파프레임으로, 바다측으로 이격된 위치에 설치된 방파프레임은 원안(遠岸) 방파프레임으로 칭한다.)(도 5 참조)Wave pressure and beach flow mitigation system according to the present invention is composed of a plurality of blast frame 10 is arranged, one side of the blast frame 10 is installed in a position close to the shore is not buried from the sea floor, The other breakwater frame 10 'is installed to be exposed from the sea bottom at a position spaced to the sea side from the one side of the breakwater frame 10. (Afterwards, the breakwater frame installed in close proximity to the shore is a near eye breakwater frame. , A breakwater frame installed at a position spaced to the sea side is called an original breakwater frame) (see Fig. 5).
상기 근안 방파프레임(10)의 바람직한 설치방법은 해저면을 굴착하여 소정깊이 및 넓이의 매립터(H)를 구성하는 단계(도 4a), 상기 매립터(H)에 토목섬유(5)를 배치하는 단계(도 4b), 상기 토목섬유(5)위에 방파프레임(10)을 펼쳐서 안착하는 단계(도 4c), 상기 방파프레임(10)의 충진공간(10a)에 자갈이나 소석(小石) 등의 충진재(121)를 충진하는 단계(도 4d), 상기 방파프레임(10) 위에 고정틀(20)을 설치하는 단계(도 4e), 상기 고정틀(20)이 고정와이어(30)에 의해 고정되도록 하는 단계(도 4f)로 이루어진다.Preferred installation method of the near-eye breakwater frame 10 is to excavate the sea floor to form a landfiller (H) of a predetermined depth and width (Fig. 4a), placing the geotextiles 5 in the landfiller (H) Step (FIG. 4B), spreading and seating the break-proof frame 10 on the geotextile (5) (Fig. 4C), such as gravel or calcite (小石) in the filling space (10a) of the break-proof frame 10 Filling the filler 121 (Fig. 4d), the step of installing the fixing frame 20 on the blast frame 10 (Fig. 4e), the step of fixing the fixing frame 20 by the fixing wire 30 (FIG. 4F).
이와 같은 바람직한 설치방법에 의하면 방파프레임(10)이 매립터(H)에 매립됨으로써 해저면에 단순 안착되는 경우에 비해 그 설치상태가 견고해지며, 매립터(H)의 저면이 토목섬유(5)에 의해 덮여지는 특성상 매립터(H)의 저면이 세굴되는 경우에도 방파프레임(10)의 아래로 충진재(121)가 빠져나가서 유실되는 현상이 방지된다.According to this preferred installation method, the installation of the breakwater frame 10 is embedded in the landfiller (H), compared to the case where it is simply seated on the sea floor, and the installation state is firm, and the bottom of the landfiller (H) is made of geotextiles (5). Due to the characteristics covered by), even when the bottom surface of the landfiller H is scoured, the phenomenon in which the filler 121 escapes under the breakwater frame 10 is lost.
