일반적인 해안의 침식과 퇴적 현상은, 바다 쪽에서 밀려오는 파도와 그 파도가 해안에 부딪혀서 변환된 이안류 및 조류 ·해류 ·바람 ·하천에 의해 발생하는 연안류 등의 작용에 의한 침식과 퇴적이 반복되는 자연 현상으로 이 같은 침식과 퇴적 현상이 균형을 이루면서 해안선은 오랫동안 그 형태를 유지하여 왔다.In general, coastal erosion and sedimentation is a nature in which erosion and sedimentation occur due to the action of waves coming from the sea side and coastal streams generated by tidal currents and tides, tides, oceans, wind, and streams converted by the waves. The phenomenon has balanced this erosion and sedimentation, and the shoreline has been in its shape for a long time.

그러나 근래에는 방파제와 도류제 및 해안 도로 같은 인공 구조물이 속속 구축되면서 그 구조물로 인하여 파도와 이안류 및 연안류의 크기와 방향이 바뀌면서 예기치 못한 곳에서의 해안 침식과 퇴적 현상이 발생되고 있다.In recent years, however, as artificial structures such as breakwaters, anchorages, and coastal roads are built one after another, the size and direction of waves, lanyards, and coastal streams have changed, causing coastal erosion and sedimentation at unexpected locations.

이에 지난 수십 년간 상기 해안 침식 현상을 막기 위한 방편으로 여러 국가와 많은 사람들이 이안제와 돌제 및 잠제같은 구조물을 개발 설치해 왔다. 그러나 해안 침식의 원인을 제대로 이해하지 못하고 설치된 상기의 구조물들은 오히려 해안 침식을 확장 가속시키는 문제점을 야기시키고 있다.In the past decades, many countries and many people have developed and installed structures such as languages, jetties and submerged as a way to prevent the coastal erosion. However, the above structures installed without understanding the cause of coastal erosion cause a problem of expanding and accelerating the coastal erosion.

본 발명은 상기와 같은 종래기술의 여러 가지 문제점을 해결하기 위한 것으로서, 파도에 의한 해안가의 침식을 줄이고, 해안가에 침식이 발생되어도 침식에 의한 토사가 해안가에서 유실되지 않도록 한 해안 바닥 침식 방지 구조물을 제공하려는데 그 목적이 있다.The present invention is to solve the various problems of the prior art as described above, to reduce the erosion of the shoreline by the waves, even if the erosion occurs on the shoreline to prevent the soil floor erosion structure by the erosion is not lost from the shoreline The purpose is to provide.

상기와 같은 목적을 달성하기 위한 본 발명에 따른 해안 바닥 침식 방지 구조물은, 해안가로부터 일정 거리 이격되며 직선부와 곡선부로 이루어져 상기 해안가에 토사퇴적부를 형성하는 토사유실방지블록과, 상기 토사퇴적부에 설치되어 토사의 퇴적을 유도하는 토사퇴적 유도망을 포함하여 구성된 것을 특징으로 한다.The coastal bottom erosion prevention structure according to the present invention for achieving the above object is, a sediment loss prevention block to form a soil sedimentation portion on the shore consisting of a straight line and a curved portion spaced apart from the shore by a predetermined distance, and the soil sedimentation portion It is characterized in that it is configured to include a sedimentation induction network to induce sediment deposition.

토사유실방지블록(10)은 해안가로(1)부터 바다쪽으로 일정 영역 내에 토사가 퇴적되도록 하여 해안 바닥의 침식을 막기 위한 것으로, 해안가(1)에 바다를 향해 직선으로 형성되는 직선부(11) 및 직선부(11)의 단부에 그 중앙이 연결되어 해안가(1) 쪽에 토사퇴적부(30)를 형성하는 곡선부(12)로 이루어져 해안가(1)를 따라 상호 간에 일정 간격을 두고 일렬로 설치된다.The earth and sand loss prevention block 10 is to prevent erosion of the bottom of the shore by depositing soil within a predetermined area from the seaside road 1 to the sea, and a straight portion 11 formed in a straight line toward the sea on the seaside 1. And a curved portion 12 having a center connected to an end portion of the straight portion 11 to form a sedimentation deposit portion 30 on the shore 1 side, and arranged in a line with a predetermined distance from each other along the shore 1. do.

토사유실방지블록(10)의 직선부(11)와 곡선부(12)는 직선부(11)와 곡선부(12)의 형태를 따라 내부에 공간을 갖도록 배열되며 하단의 첨예부(13a)를 통해 각각 해저(2)에 박혀 일부분이 해저로부터 일정 높이로 세워지고 해수에 잠기는 다수의 방호말뚝(13) 및 방호말뚝(13) 사이의 공간에 채워지는 채움재(14)로 이루어진다. 즉, 토사유실방지블록(10)의 직선부(11)와 곡선부(12) 및 해안가(1)의 사이에는 토사퇴적부(30)가 형성되어 해류와 함께 바다로 밀려나가는 토사(S)가 토사퇴적부(30)에 퇴적되도록 하는 것이다.The straight portion 11 and the curved portion 12 of the earth and sand loss prevention block 10 are arranged to have a space therein along the shape of the straight portion 11 and the curved portion 12, and the sharpened portion 13a at the bottom thereof. Each part is embedded in the seabed (2) through a portion made of a filling material 14 is filled in the space between the plurality of protection piles 13 and the protection pile 13 is erected from the sea floor to a certain height. That is, the earth and sand (S) is formed between the straight portion 11, the curved portion 12 and the shore 1 of the earth and sand loss prevention block 10 is pushed to the sea with the current flow. It is to be deposited in the soil depositing portion (30).

토사퇴적 유도망(20)은 토사퇴적부(30)를 덮어 해안가(1)로 밀리는 해류의 속도를 줄여 토사(S)의 퇴적을 유도하는 것으로, 다수개(도면에는 2개로 도시됨)가 토사퇴적부(30)에 다단으로 배치되며 둘레부가 직선부(11)와 곡선부(12)에 연결고리(21)를 통해 연결되면서 나머지 둘레부는 해저(2)에 안착되는 콘크리트블록(22)을 통해 지지되어 펼쳐진 상태를 유지한다.The sedimentary sedimentation guide network 20 covers the sedimentary sedimentation unit 30 to reduce the speed of the current flowing to the shore 1 to induce sediment (S). It is arranged in multiple stages in the retreat portion 30 and the circumference is connected to the straight portion 11 and the curved portion 12 through the connecting ring 21, the remaining circumference through the concrete block 22 is seated on the seabed 2 Stay supported and unfolded.

그리고, 토사유실방지블록(10)들의 사이에는 이물질이 바다로 유입되지 않도록 차단하는 이물질 수거망(40)이 설치될 수 있다.And, between the soil loss prevention block 10 may be installed foreign matter collection network 40 to block foreign matter from entering the sea.

해안가(1)에서부터 방호말뚝(13)들을 내부에 공간이 형성되도록 2열로 배열하면서 첨예부(13a)를 해저(2)에 박아 직선부(11)와 곡선부(12)를 형성하고, 방호말뚝(13)들 사이의 공간에 채움재(14)를 채워 토사유실방지블록(10)을 시공한다. 이러한 방법으로 다수의 토사유실방지블록(10)들을 해안가(1)를 따라 일렬로 시공하면, 토사유실방지블록(10)들의 곡선부(12)의 후방에는 토사퇴적부(30)가 마련된다. 이 토사퇴적부(30)에 토사퇴적 유도망(20)을 설치하고, 토사유실방지블록(10)들의 사이에 이물질 수거망(40)을 설치하여 본 발명의 해안 바닥 침식 방지구조물(100)의 시공을 완료한다.Arranged in two rows to form a space inside the protective piles 13 from the shore (1) while driving the sharp portion (13a) to the seabed (2) to form a straight portion 11 and a curved portion 12, Fill the filling material 14 in the space between the (13) to construct a soil loss prevention block (10). In this way, when a plurality of soil loss prevention block 10 is constructed in a line along the coast 1, the soil depositing portion 30 is provided behind the curved portion 12 of the soil loss prevention block 10. The earth and sand sedimentation guide network 20 is installed in the soil sedimentation unit 30, and the foreign matter collection network 40 is installed between the earth and sand loss prevention block 10 of the coastal floor erosion prevention structure 100 of the present invention. Complete construction.

바다에서 해안가(1)로 해류가 밀려올 때 해류에 의한 파도에 의해 해안가(1)가 침식되어 토사가 해류와 함께 바다쪽으로 흘러 내려간다. 이때, 해류와 토사(S)는 토사유실방지블록(10)의 직선부(11)와 곡선부(12)의 내면을 따라 흐르게 되며, 해류는 토사퇴적 유도망(20)에 부딪쳐 속도가 낮아지게 되어 토사(S)가 토사퇴적부(30)에 가라앉아 토사(S)가 없는 상태의 해류만 바다쪽으로 흘러 나가게 된다.When the current flows from the sea to the shore (1), the shore (1) is eroded by the waves caused by the current, and the earth and sand flow down toward the sea with the current. At this time, the current and the soil (S) flows along the inner surface of the straight portion 11 and the curved portion 12 of the earth and sand loss prevention block 10, the current flow hits the sedimentary induction network 20 to be lowered in speed As a result, the earth and sand (S) sinks in the soil depositing portion (30), so that only the currents without the soil (S) flow out toward the sea.

한편, 해안가(1)로 밀려 들어오는 해류는 토사유실방지블록(10)들 사이의 공간을 통해 해안가(1)로 유입된다(이물질 수거망(40)이 적용된 경우 이물질 수거망(40)을 통과하여 이물질이 여과된 상태로 유입). 이때, 해류는 곡선부(12)의 곡면을 따라 흐르게 되어 직선부(11)와 곡선부(12) 사이의 토사퇴적부(30)로 유입되며, 해류는 토사퇴적 유도망(20)에 부딪치게 되어 속도가 떨어지게 되고, 해류에 포함된 토사(S)가 해저(2)로 가라앉게 된다. 즉, 해안가(1)에서 바다로 밀려나가는 해류에는 토사(S)가 없는 상태로 다시 바다쪽으로밀려 나가게 되는 것이다.On the other hand, the current flowing into the shore (1) is introduced into the shore (1) through the space between the soil loss prevention block 10 (if the foreign matter collection network 40 is applied through the foreign matter collection network 40 Foreign substance is filtered out). At this time, the current flows along the curved surface of the curved portion 12 and flows into the sedimentary deposit portion 30 between the straight portion 11 and the curved portion 12, and the current flow hits the sedimentary induction network 20. The speed drops, and the earth and sand contained in the current (S) sinks to the seabed (2). In other words, the sea current that is pushed to the sea from the shore (1) will be pushed back toward the sea without the soil (S).

해류가 이물질 수거망(40)을 통해 바다쪽으로 밀려나갈 때 해안가(1)에 있는 이물질은 이물질 수거망(40)에 의해 여과되어 바다를 오염시키지 않게 된다.When the current is pushed toward the sea through the foreign matter collection network 40, foreign matter on the shore 1 is filtered by the foreign matter collection network 40 so as not to pollute the sea.

이상에서 설명한 바와 같이 본 발명에 따른 해안 바닥 침식 방지 구조물에 의하면, 파도에 의해 해안가가 침식되어도 침식에 의해 발생된 토사가 해안가를 벗어나지 않고 해안가에 퇴적되므로 해안가의 면적 축소가 없으며, 근해에 서식하는 생태계를 보호할 수 있다.As described above, according to the coastal floor erosion prevention structure according to the present invention, even if the shoreline is eroded by the waves, the soil generated by the erosion is deposited on the shoreline without leaving the shoreline, so there is no reduction in the area of the shoreline, Protect the ecosystem
