Description

호안 방파제의 테트라포드{THE TETRAPOD OF BREAKWATER FOR EMBANKMENT}Tetrapod of shore bank breakwater {THE TETRAPOD OF BREAKWATER FOR EMBANKMENT}

본 발명은 해안의 방파제 또는 호안 등을 구축할 시 방파제 또는 호안 등의 외해측 경사면을 보호하기 위하여 거치되는 테트라포드(Tetrapod)에 관한 것으로 좀더 구체적으로는 테트라포드의 체적 당 하중을 증가시키기 위해 콘크리트 보다 비중이 높은 철광석을 내재시킨 상태로 테트라포드를 성형토록 함으로써 기존의 콘크리트만으로 구성되는 테트라포드에 비해 체적당 하중이 증가되도록 하여 거치 후 해수의 흐름이나 파도에 영향을 받지 않고 거치된 위치를 안정되게 고수할 수 있도록 하여 무단의 위치변동이나 유실을 방지할 수 있도록 함으로써 방파기능을 개선할 수 있도록 한 것이다.The present invention relates to a tetrapod which is mounted to protect the offshore side slopes such as a breakwater or a shelter when constructing a coastal breakwater or a shelter, and more specifically, to increase the load per volume of the tetrapod. The tetrapod is molded with this high iron ore in the state so that the load per volume can be increased compared to the tetrapod composed of conventional concrete only, so that the stationary position can be stably held without being affected by the flow or waves of seawater after the fermentation. It is to improve the breaking function by preventing unauthorized change of position or loss.

통상적으로 외해(外海)로부터의 파랑(波浪)을 막아서 항내를 정온(靜穩)하게 유지하기 위한 축조물. 인공 항에는 보통 방파제가 필요하다.A building for keeping the harbor at a constant temperature, usually by blocking waves from the open sea. Artificial ports usually require breakwater.

상기 방파제 또는 호안은 일정한 크기의 사석을 일정한 구배의 기울기로 구축한 다음 사석보다 현저히 큰 크기의 피복석을 포설하여 방파제 또는 호안을 축조 하게되는바, 그러나 피복석으로 사용되는 자연석은 그 부존량이 절대 부족하여 이자연석 대신으로 다양한 형태와 구조의 블럭을 콘크리트로 제작하여 이를 피복하고 이 블럭상면에 4개의 지간이 방사상으로 돌설된 구조의 테트라포드를 정적 또는 난적하여 방파제 또는 호안의 피복을 하여 왔다.The breakwater or revetment is to build a stone of a certain size with a gradient of a constant gradient and then to install a reclaimed stone of a size significantly larger than that of the sandstone to build a breakwater or revetment, but the natural stone used as a cladding stone is absolutely insufficient Instead of this natural stone, blocks of various shapes and structures are made of concrete and coated, and tetrapods of the structure with four sections radially protruding on this block have been statically or roughly coated with breakwaters or lakes.

하지만 기존의 테트라포드는 철제 거푸집을 조립하여 이에 콘크리트 몰드를 채우고 약 28일간 양생하여 콘크리트 테트라포드를 완성한 다음 운반하여 내항 또는 외항 방파제에 거치하였다.However, the existing tetrapods were assembled with iron formwork, filled with concrete molds, and cured for about 28 days to complete the concrete tetrapods, and then transported and mounted on the inner or outer breakwater.

하지만 이와 같은 종래의 콘크리트 테트라포드는 전체가 비중이 크지 못한 콘크리트 몰드를 이용하여 구성되는 것이므로 거치된 상태에서 가해지는 조수나 파도의 엄청난 힘을 버텨내기에 부족한 실정이었다.However, such a conventional concrete tetrapod is composed of a concrete mold that does not have a large specific gravity, so it was insufficient to endure the enormous force of tides or waves applied in the mounted state.

따라서 해수의 흐름이 거칠 경우 자주 위치가 변동되고 심한 경우 거치 위치에서 많이 벗어나 유실되는 경우가 있어 조적의 연결상태가 와해되어 방파 기능을 제대로 수행하지 못하게 되는 문제를 노출하게 되는 것이다.Therefore, when the seawater flow is rough, the position is frequently changed, and in the severe case, the position may be lost a lot out of the mounting position, thereby exposing the problem that the connection state of the masonry is broken and the breakwater function cannot be performed properly.

더욱이 방파제 또는 호안의 경사면에 피복한 기존의 블럭은 질서 있게 조적하거나 무질서하게 피복한 경우이나 일단 피복작업이 완료된 후에는 별다른 유실방지수단이나 시설이 없어 자체적으로 유실이 억제될 수 있는 기능의 보유가 절실하게 요구되어 왔다.Furthermore, existing blocks coated on the slopes of breakwaters or lakes have a function that can be prevented on their own because they are orderly or unorderedly coated or there is no loss prevention means or facility once the coating work is completed. There has been an urgent need.

본 발명은 상기와 같은 기존 구조의 테트라포드에서 기인되는 제반 문제점을 해결 보완하기 위하여 안출된 것으로 본 고안의 목적은 콘크리트만으로 구성되는 테트라포드에 비해 체적당 하중이 증가되도록 하여 거치 후 해수의 흐름이나 파도에 영향을 받지 않고 거치된 위치를 안정되게 고수할 수 있도록 하여 무단의 위치변동이나 유실을 방지할 수 있는 테트라포드를 제공함에 있는 것이며.The present invention was devised to solve the problems caused by the tetrapod of the existing structure as described above, the object of the present invention is to increase the load per volume compared to the tetrapod composed of concrete only to the flow or wave after seawater It is to provide a tetrapod that can stably adhere to the mounted position without being affected, thereby preventing unauthorized position shift or loss.

상기와 같은 목적을 달성하기 위하여 본 발명은 테트라포드의 체적 당 하중을 증가시키기 위해 콘크리트 보다 비중이 높은 철광석을 내재시킨 상태로 테트라포드를 성형토록 한 것으로 이하 첨부되는 도면에 의거 본 발명의 구성을 상세하게 설명하면 다음과 같다.In order to achieve the above object, the present invention is to form a tetrapod in a state in which iron ore having a specific gravity higher than concrete in order to increase the load per volume of the tetrapod in accordance with the accompanying drawings in detail the configuration of the present invention The explanation is as follows.

도 1은 본 발명의 요부 절개 사시도이고, 도 2는 본 고안의 단면 예시도로서,1 is a perspective view of the main portion of the present invention, Figure 2 is a cross-sectional view of the present invention,

통상적으로 철광석은 경제적으로 채광작업을 할 수 있는 철을 함유한 광석으로서, 자철석·적철석·갈철석을 주로 하고, 때로는 능철석(菱鐵石)도 이용된다.Typically, iron ore is an ore containing iron that can be economically mined, mainly magnetite, hematite and brown iron, and sometimes tungsten is also used.

보통은 함철량(含鐵量)에 따라 60 % 이상의 것을 부광(富鑛), 40 % 이하의 것을 빈광(貧鑛)이라고 하며 빈광은 함철량이 적어 제철원료로 사용되지 않게되어 그 쓰임새가 적고 일반석보다 상대적으로 비중이 높은 철광석의 물리적 특성을 살릴 수 있는 특정의 용도를 개발하지 못해 많은 량의 빈광이 일반석과 같이 단순한 용도에 사용되는 것이 대부분이었다.Normally, more than 60% of the iron is rich in richness and less than 40% is called poor ore. Binite has less iron content and is not used as a raw material for steel. Because of the lack of development of specific applications that can take advantage of the physical properties of more or less iron ore, large amounts of unoccupied ore have been used for simple applications such as ordinary ore.

따라서 본 발명은 철광석의 고비중의 특성을 최대한 효과적으로 이용할 수 있도록 콘크리트와 철광석을 결합하는 고하중의 테트라포드(1)를 구성하기에 이른것으로,Therefore, the present invention is to construct a high-loaded tetrapod (1) to combine concrete and iron ore so as to effectively utilize the high specific gravity of iron ore,

본 발명은 함철량이 40%이하로서 제철용으로 적합지 않은 함량미달의 빈광(貧鑛)을 소정 크기의 그래뉼 형태로 분쇄하여 중량부재(2)를 구성한 다음 이를 테트라포드의 성형 시 거푸집의 내부에 투입시켜 콘크리트 몰드와 함께 양생되도록 함으로써 내부에는 콘크리트보다 비중이 큰 철광석으로 된 중량부재(2)가 위치되고 중량부재(2)의 외부로는 콘크리트부(3)가 피복 상태로 위치되는 이중구조의 테트라포드(1)를 구성토록 하여 기존의 콘크리트만으로 구성되는 테트라포드에 비해 동일한 체적을 기준으로 상대적으로 고(高) 하중을 가질 수 있도록 한 것이다.In the present invention, the iron content is less than 40% by grinding the granules of less than unsuitable content for steelmaking in the form of granules of a predetermined size to form a weight member (2) and then put it into the formwork when forming the tetrapod By curing with the concrete mold, the weight member (2) made of iron ore having a greater specific gravity than the concrete inside is located, and the outer side of the weight member (2) is a tetrapod of dual structure in which the concrete part (3) is placed in a coated state ( In order to construct 1), it is possible to have relatively high load based on the same volume as compared to tetrapod composed of existing concrete only.

이와 같이 구성되는 본 발명의 테트라포드(1)는 그래뉼 상태의 중량부재(2)의 각 틈새로 콘크리트가 빈틈없이 스며들어 충진된 상태에서 양생됨으로써 강도가 저하되는 일은 발생되지 않으며 고하중을 갖게 되는 것이므로 거치 상태에서 파도나 조수 등의 외력이 가해지더라도 보다 안정되게 위치를 고수하는 것이 가능하게 되는것이다.Since the tetrapod 1 of the present invention configured as described above is cured in a state filled with concrete soaked into each gap of the weight member 2 in the granulated state, it does not occur to decrease the strength and thus has a high load. Even if an external force such as waves or tides is applied in a stationary state, it becomes possible to hold the position more stably.

한편 상기 본 발명의 테트라포드(1)에서 함유되는 중량부재(2)의 비율은 특별하게 한정되는 아니나 테트라포드(1)의 강도나 내구성 등 제반 조건을 고려하게 적절하게 설정하면 된다.The ratio of the weight member 2 contained in the tetrapod 1 of the present invention is not particularly limited, but may be appropriately set in consideration of various conditions such as strength and durability of the tetrapod 1.

이상과 같이 본 발명의 테트라포드는 고비중의 철광석을 내재하게 됨으로써 콘크리트만으로 구성되는 기존의 테트라포드에 비해 체적 당 하중이 크게 증가되어 거치 상태에서 해수의 흐름이나 조수 및 파도에 영향을 받지 않고 거치된 위치를 안정되게 고수할 수 있게됨으로써 방파 기능을 크게 개선할 수 있는 효과가 있는 것이다.As described above, the tetrapod of the present invention has a high specific weight of iron ore, and thus the load per volume is greatly increased compared to the existing tetrapod composed of concrete alone, and thus the tetrapod is mounted without being affected by the flow of the seawater, tides and waves. By being able to hold stably, there is an effect that can greatly improve the breaking function.
