従来、コンクリ−ト廃棄物や間伐材等の産業廃棄物を利用した様々な人工魚礁が検討されている。
コンクリ−ト廃棄物を利用したものとしては、コンクリート構造物の解体に際して発生する廃棄物を所定寸法に切断し、或いは端部のみ切断してできるコンクリート廃棄部材を近海、沿海、港湾又は河川などの水域に沈下して魚礁とするものがある。
また、（特許文献１）には、コンクリートを基礎に木質系材料を組み込んで構成した複合型人工漁礁が開示されている。
さらに、漁場を人工的に作り出すために、大型のコンクリートブロックや金属、石、各種ひも類、各種プラスチック類を藻類の植生基材とすべく海中等に投下し、人工の藻場を形成させて魚類を集めることなども行われている。
また、（特許文献２）では、海底等に沈設された餌料生物増殖礁を所定期間経過毎に船で引き上げ、餌料生物増殖基質材を取り替えることにより、増殖効果を一定以上に維持する方法が提案されている。 Conventionally, various artificial fish reefs using industrial waste such as concrete waste and thinned wood have been studied.

しかしながら、上記従来の技術では、以下のような課題を有していた。
（１）コンクリート廃棄部材を利用する人工魚礁は、整い過ぎた単調、或いは規則的な形状を有しており、表面も均整化、平滑化されているため、貝類や海藻類等がその表面に棲息或いは付着し難く、従って、これら貝類や海藻類等を餌料とする魚類の集魚効果に欠けるという課題を有していた。
（２）（特許文献１）のように、コンクリートを基礎に木質系材料を組み込んで構成したものは、時間の経過により木質系材料が水棲生物などに食い荒らされるため、耐久性がなく、木質系材料のコンクリート基礎との接合部分が食害された場合は、木質系材料が海水表面に浮上し、船舶などの航行の障害となるなどの課題を有していた。
（３）大型のコンクリートブロックや金属、プラスチック類等を海中等に投下し、人工の藻場を形成するものは、表面が平滑であるため藻類の根が基材に付着できず、水中に流亡したり、これらの基材が長期に渡って分解することなく水中に残留したりして、かえって有用な海藻類を駆逐してしまうという課題を有していた。
（４）（特許文献２）では、基台となる大型のコンクリートブロックの重量が重いため、引き上げに大掛かりな設備が必要で、設置し直すための作業が困難であり、設置作業性、省資源性、環境保護性に欠けるという課題を有していた。 However, the above conventional techniques have the following problems.
(1) Artificial fish reefs that use concrete waste members have a monotonous or regular shape that is too tidy, and the surface is also smoothed and smoothed, so shellfish and seaweed are on the surface. It was difficult to inhabit or adhere to, and therefore, there was a problem that the fish collection effect of fish using these shellfish, seaweeds and the like as feed was lacking.
(2) As in (Patent Document 1), a material that is constructed by incorporating a wood-based material on the basis of concrete is not durable because the wood-based material is eaten by aquatic organisms over time, and is not durable. When the joint part of the material with the concrete foundation is damaged, the woody material floats on the surface of the seawater and has problems such as obstruction of navigation of ships.
(3) Large concrete blocks, metals, plastics, etc. that are dropped into the sea to form artificial seaweed beds have a smooth surface, so the roots of the algae cannot adhere to the substrate and run away in the water. However, these base materials remain in the water without being decomposed for a long period of time, so that they have a problem of destroying useful seaweeds.
In (4) (Patent Document 2), the large concrete block that is the base is heavy, requiring large equipment for lifting, making it difficult to perform re-installation, installation workability, and resource saving. Have the problem of lacking in environmental protection.

本発明は上記課題を解決するもので、川岸、海岸、港湾等の護岸のために設置されるＬ型擁壁等の立壁部を有効利用することにより、藻礁や漁礁等の水中設置物だけでなく、梯子や防舷材等の付属設置物、或いは柵、標識、案内板等の各種地上設置物を容易に着脱することができる量産性、機能性、環境保護性に優れた護岸構造物の提供を目的とする。 The present invention solves the above-mentioned problems, and by effectively using standing walls such as L-shaped retaining walls that are installed for revetment such as riverbanks, coasts, and harbors, only underwater installations such as alga reefs and fishing reefs In addition, the revetment structure with excellent mass productivity, functionality, and environmental protection that can easily attach and detach attachments such as ladders and fenders, or various ground installations such as fences, signs, and guide plates The purpose is to provide.

ここで、生物共生部の形状、大きさ、材質、配置等は適宜、選択することができる。
パネル状に形成した生物共生部は藻礁として好適に用いられる。この場合、例えば大鋸屑や木屑等のほか、萱や葦などの草、植物の茎などを切断した各種植物材料をセメントなどに混入して加圧成形したものやポリエステルやエポキシ等の熱硬化性樹脂を結合材として木材、鉄等の金属、砂、砕石、炭酸カルシウム等の各種骨材を固めたもの、常温硬化型の二液性エポキシ樹脂等を用いて木材や石材等を固めたもの、コンクリートをガラス繊維で強化したものなど様々なものを用いることができ、使用する素材の選択と組合せにより、重量、比重、強度等を調整することができる。尚、セメントや砂の代わりにフライアッシュを用いた低アルカリコンクリート製のパネルでは、嫌アルカリ藻類の繁茂を促進することができる。また、コンクリートにアルギニン等のアミノ酸を加えた場合、アミノ酸がコンクリート表面にゆっくり染み出し、海藻類の成長を促すことができると共に、その匂いによって魚類を寄せ集めることもできる。さらに、必要に応じて、海藻類等が付着し易くなるように表面を凹凸や孔等で粗面化したり、表面に鉄岩化塗料を塗布して鉄分を溶出させたりして、集魚効果を高めることができる。生物共生部は、表面に凹凸を形成したり、表面を粗面化したりする代わりに、目の粗いポーラスレジンコンクリート等を用いて形成してもよい。また、生物共生部の固定に用いるアンカー部材の雌部材の先端を生物共生部の表面から突出させて突起部として利用し、ツルアラメ等の海藻類を付着させるようにすることもできる。或いは、麻、ワイヤー、ロープ等で形成された紐状の生物共生部の端部を立壁部の表面から突出させた雌部材等に結びつけて海藻類の養殖等に用いることもできる。
さらに、空隙に予め昆布や若布の菌を打ち込んだり、海藻類の栄養分となる窒素やリンを混入させたり、表面に貝殻や蠣殻等を付着させたりしてもよい。尚、海藻類は魚貝類の餌になるだけでなく、光合成で二酸化炭素を吸収したり、水中の窒素やリンを吸収したりして水質浄化に貢献することができる。 Here, the shape, size, material, arrangement, and the like of the symbiotic part can be appropriately selected.
The symbiotic part formed in a panel shape is suitably used as an algal reef. In this case, for example, in addition to large sawdust and wood chips, various plant materials obtained by cutting grass such as firewood and firewood, plant stems, etc., mixed with cement, etc., are pressure-molded, and thermosetting resins such as polyester and epoxy A combination of wood, iron and other metals, sand, crushed stone, calcium carbonate, etc., solidified wood, stone, etc. using room temperature curable two-component epoxy resin, concrete Various materials such as those reinforced with glass fiber can be used, and the weight, specific gravity, strength, and the like can be adjusted by selecting and combining the materials used. In addition, in the panel made of low alkali concrete using fly ash instead of cement or sand, the overgrowth of the alkali-free algae can be promoted. Further, when an amino acid such as arginine is added to concrete, the amino acid can slowly ooze out on the concrete surface to promote the growth of seaweeds, and fish can be gathered by the smell. In addition, if necessary, the surface can be roughened with irregularities or holes so that seaweed etc. can easily adhere to it, or iron can be applied to the surface to elute the iron content, resulting in a fish collection effect. Can be increased. Instead of forming irregularities on the surface or roughening the surface, the symbiotic part may be formed using porous resin concrete or the like having a coarse mesh. Further, the tip of the female member of the anchor member used for fixing the symbiotic part can be projected from the surface of the symbiotic part and used as a protruding part to attach seaweeds such as crane lambs. Alternatively, the end of the string-like symbiotic part formed of hemp, wire, rope or the like can be connected to a female member or the like that protrudes from the surface of the standing wall part and used for seaweed culture or the like.
Further, kelp or young cloth bacteria may be implanted in the voids in advance, nitrogen or phosphorus as nutrients for seaweeds may be mixed, or shells, rice husks, etc. may be attached to the surface. In addition, seaweeds can contribute not only to fish and shellfish but also to water purification by absorbing carbon dioxide through photosynthesis or absorbing nitrogen and phosphorus in water.

鋳鉄、鉄骨、ステンレス鋼等の金属や木材等で複数の開口部を有する箱形（中空）のフレーム状に形成した生物共生部は、漁礁として好適に用いられる。波などによる外力を受け難く、軽量化を図ることができると共に、内部に新鮮な海水を通すことができ、内部空間を魚の棲息空間や通り道として集魚効果を高めることができるためである。
生物共生部は、鋳鉄、鉄、ステンレス鋼等の金属やポリエチレン、ポリプロピレン、ポリスチレン等の合成樹脂でカゴ状に形成することもできる。この場合、上記金属製や合成樹脂製のフレーム（枠体）の開口部に、同様の材質で形成された網体或いは多孔性のパンチングメタルやエキスパンドメタルを貼着したものが好適に用いられる。カゴ状の生物共生部の内部には、従来から漁礁や養殖場の材料として用いられている鉄鋼スラグ、石炭灰造粒物、カキ殻、焼却灰、ゼオライト、コンクリートブロック、石、鉄炭団子等の鉄イオン溶出体等を収容することができる。これにより、集魚効果や水質改善効果を得ることができる。特に、鉄炭団子等の鉄イオン溶出体を収容した場合、水中に溶出した鉄イオンが、赤潮やアオコ等の発生原因となるリン等と化学反応して、有害プランクトンの発生を抑制できる。また、鉄イオンが水中の化学物質と結合し、それをミネラルとして吸収した水中生物が増加、活性化することにより、光合成が活発になり、水質の改善効果が得られる。尚、これらの収容物は単独で用いてもよいし、複数種を適宜、組合せて用いてもよい。 A symbiotic part formed in a box-shaped (hollow) frame shape having a plurality of openings made of metal such as cast iron, steel frame, stainless steel, or wood is suitably used as a fishing reef. This is because it is difficult to receive external force due to waves and the like, and can be reduced in weight, and fresh seawater can be passed through it, so that the fish collection effect can be enhanced by using the internal space as a habitat or passage for fish.
The symbiotic part can also be formed in a cage shape with a metal such as cast iron, iron or stainless steel, or a synthetic resin such as polyethylene, polypropylene or polystyrene. In this case, a metal body or a synthetic resin frame (frame body) having a net or porous punching metal or expanded metal made of the same material is preferably used. Inside the cage-like symbiotic part, steel slag, coal ash granulated material, oyster shell, incineration ash, zeolite, concrete block, stone, steel coal dumpling, etc., which are conventionally used as materials for reefs and farms The iron ion eluate and the like can be accommodated. Thereby, the fish collection effect and the water quality improvement effect can be acquired. In particular, when iron ion eluents such as iron charcoal dumplings are accommodated, the iron ions eluted in the water can chemically react with phosphorus and the like that cause red tides, blue sea cucumbers, etc., and the generation of harmful plankton can be suppressed. In addition, when the aquatic organisms that bind with chemical substances in water and absorb them as minerals are increased and activated, photosynthesis becomes active and an effect of improving water quality is obtained. In addition, these accommodations may be used independently and may be used in combination of multiple types suitably.
