Description

本発明は海藻用育成場に関するものである。   The present invention relates to a seaweed breeding ground.

近年、環境意識の高まりとともに、防波堤や護岸などの港湾・漁港・海岸構造物において、構造物本来の機能だけではなく藻場造成が可能な空間が意図的に提供され、ここでアラメ、カジメ、ホンダワラなどの有用海藻類が造成されている。このような海藻用育成場として、図８に示すように、直立混成堤１６の前面に人工リーフ１７を設置したものと、傾斜基盤を有する構造物１８に小段１９を設けたものと、遊水室２０を備えた直立スリットケーソン２１とがある。またこの他にも例えば、特許第２９７１００７号公報の発明がある。
特許第２９７１００７号公報 In recent years, with the heightened environmental awareness, in harbors, fishing ports, coastal structures such as breakwaters and seawalls, a space that can be used not only for the original functions of the structure but also for the creation of seaweed beds is provided. Useful seaweeds such as Honda Walla have been created. As such a seaweed breeding ground, as shown in FIG. 8, an artificial leaf 17 is installed on the front surface of an upright mixed bank 16, a structure 18 having an inclined base is provided with a step 19, 20 and an upright slit caisson 21. In addition, for example, there is an invention of Japanese Patent No. 2971007.
Japanese Patent No. 2971007

しかし、上記のような人工リーフや傾斜堤などは、多くの捨て石や根固・波消ブロックを必要とするためコストがかかる。一方、直立スリットケーソンの遊水室内部は、透過壁や堤体に囲まれているため、底面まで光が届きにくく必要な光量が不足するという問題があった。   However, such artificial reefs and sloping dams as described above are costly because they require many discarded stones, root anchors and wave-dissipating blocks. On the other hand, there is a problem in that the necessary amount of light is insufficient because it is difficult for light to reach the bottom surface because the inside of the water chamber of the upright slit caisson is surrounded by a transmission wall and a bank.

本発明は上記のような問題に鑑みてなされたものであり、その目的は、コストをかけず、かつ必要な光量が得られる海藻用育成場を提供することである。   The present invention has been made in view of the above problems, and an object thereof is to provide a seaweed breeding ground that does not require cost and can provide a necessary amount of light.

本願発明の海藻用育成場は、防波堤の港外側面に設置されたケーソンを構成する堤体の前面に、前面側に突出した底部と、該底部先端に立設したスリットを有する透過壁とにより、上面が開口した断面Ｕ字形の遊水室が形成され、該遊水室の水面近傍には上下を仕切る仕切板が設置されて海藻造成浅場が形成されてなることを特徴とする。また仕切板は防波堤側に向かって上側に傾斜したことを含む。また仕切板は段差状であることを含む。また仕切板には通水孔、突起、溝のいずれかが形成されたことを含むものである。 The seaweed breeding ground of the present invention comprises a bottom protruding from the front side of the dam body constituting the caisson installed on the outer surface of the port of the breakwater, and a transmission wall having a slit erected on the tip of the bottom. , the upper surface is formed retarding chamber cross-section U-shaped opening, the water surface near of the free water chamber, characterized in that formed by seaweed Construction shallow partition plate for partitioning the vertically is installed form. Moreover, the partition plate includes being inclined upward toward the breakwater side. The partition plate includes a step shape. Further, the partition plate includes any one of water passage holes, protrusions, and grooves.

遊水室に設けた仕切板が必要な光量を得られる海藻造成浅場になるため、有用海藻類の造成が可能となる。また傾斜状または段差状の仕切板により、水深に応じた海藻を繁殖させることができる。また仕切板の突起や溝は海藻類の定着を促進させる。また仕切板の通水孔により消波性能も向上する。仕切板の下側の遊水室は魚礁としての機能を発揮する。   Since the partition plate provided in the recreational water chamber becomes a seaweed formation shallow ground where the necessary amount of light can be obtained, it is possible to create useful seaweeds. Moreover, the seaweed according to the water depth can be propagated by the inclined or stepped partition plate. In addition, the projections and grooves on the partition plate promote the establishment of seaweeds. Moreover, the wave-dissipating performance is improved by the water flow holes of the partition plate. The water play room below the partition plate functions as a fish reef.

図１は海藻用育成場Ａの斜視図であり、この海藻用育成場Ａは、防波堤ａの港外側面に連続的に設置されたケーソン１の遊水室３における水面近傍に海藻造成浅場８が形成されて構成されている。   FIG. 1 is a perspective view of the seaweed breeding ground A. The seaweed growing ground A has a seaweed formation shallow ground 8 in the vicinity of the water surface in the water chamber 3 of the caisson 1 continuously installed on the outer surface of the port of the breakwater a. Formed and configured.

海藻用育成場Ａを形成するケーソン１は、図２に示すように、鉄筋コンクリート製の堤体２の前面側、すなわち港外側面に遊水室３が形成されて構成されている。この遊水室３は堤体２前面に突出した底部４と、この底部先端に立設した透過壁５とにより、上面が開口したほぼ断面Ｕ字状に形成され、この透過壁５に形成されたスリット６により消波機能を有している。 As shown in FIG. 2, the caisson 1 that forms the seaweed breeding ground A is configured such that the water reserving chamber 3 is formed on the front side of the reinforced concrete dike body 2, that is, on the outer side of the port. The water reserving chamber 3 is formed in a substantially U-shaped section having an upper surface opened by a bottom portion 4 projecting from the front surface of the dam body 2 and a permeating wall 5 standing at the front end of the bottom portion. The slit 6 has a wave-dissipating function.

また、遊水室３の上下方向の中央部、すなわち水面近傍には上下を仕切る仕切板７が水平に設けられ、この仕切板７が必要な光量を得られる有用海藻類の造成床となって海藻造成浅場８を形成する。また仕切板７には縦方向の通水孔９が形成され、この通水孔９が消波機能を発揮するとともに、遊水室３下側への魚の通り道になって、遊水室３の下側が魚礁空間になる。   In addition, a partition plate 7 for partitioning the top and bottom is provided horizontally in the vertical center of the water reserving chamber 3, that is, in the vicinity of the water surface. The creation shallow field 8 is formed. In addition, a vertical water passage hole 9 is formed in the partition plate 7, and this water passage hole 9 exhibits a wave-dissipating function, and also serves as a fish passage to the lower side of the water reserving chamber 3. It becomes a fish reef space.

また上記の仕切板７は、防波堤ａの港外側面に設置された既存のケーソン１の遊水室３に後から設置することもできるし、新たに製造するケーソン１に最初から設置することもできる。   Moreover, said partition plate 7 can also be installed later in the water reservoir 3 of the existing caisson 1 installed in the port outer surface of the breakwater a, and can also be installed from the beginning in the newly manufactured caisson 1. .

また図３は他の実施の形態のケーソン１０である。このケーソン１０は仕切板７が堤体２側に向かって上側に傾斜したものであり、これ以外は図２のケーソン１と同じ構成である。このように仕切板７を傾斜させると海藻類が繁殖するのに十分な光量を得ることができる。   FIG. 3 shows a caisson 10 according to another embodiment. The caisson 10 has the same configuration as the caisson 1 of FIG. 2 except that the partition plate 7 is inclined upward toward the dam body 2 side. When the partition plate 7 is tilted in this way, a sufficient amount of light can be obtained for the propagation of seaweeds.

また図４も他の実施の形態のケーソン１１である。このケーソン１１は段差状の仕切板１２を設けたものであり、これ以外は図２のケーソン１と同じ構成である。このように段差状の仕切板１２を設けると水深に応じた海藻類を繁殖させることができる。また、この仕切板１２も上記のように傾斜させることができる。   FIG. 4 also shows a caisson 11 according to another embodiment. This caisson 11 is provided with a step-like partition plate 12, and the other configuration is the same as that of the caisson 1 of FIG. Thus, when the step-shaped partition plate 12 is provided, seaweeds according to the water depth can be propagated. The partition plate 12 can also be inclined as described above.

また図５は仕切板７の通水孔９の他の実施の形態であり、（１）は通水孔９を横方向に設けたものであり、（２）および（３）は平面円形または角形の通水孔９を設けたものである。また図６は通水孔９に代わって突起１３および溝１４を設けたものであり、（２）および（４）に示すような、帯状や点状の突起１３や、（１）および（３）に示すような、帯状や点状の溝１４を設けることができ、これらの突起１３や溝１４によって海藻類が着床しやすくなる。   FIG. 5 shows another embodiment of the water flow hole 9 of the partition plate 7. (1) is a water flow hole 9 provided in the lateral direction, and (2) and (3) are planar circular or A square water hole 9 is provided. Further, FIG. 6 is provided with a projection 13 and a groove 14 instead of the water passage hole 9, and as shown in (2) and (4), a band-like or dot-like projection 13, or (1) and (3 ) And strip-like grooves 14 as shown in FIG. 6 can be provided, and these projections 13 and grooves 14 make it easy for seaweeds to land.

また図７は、仕切板７を設けたケーソンと、仕切板７を設けないケーソンとの消波特性を比較したものであり、仕切板７を設けたケーソンの方が消波機能を発揮することを確認することができた。   FIG. 7 shows a comparison of the wave-dissipating characteristics of the caisson provided with the partition plate 7 and the caisson not provided with the partition plate 7. The caisson provided with the partition plate 7 exhibits a wave-dissipating function. I was able to confirm that.
