「産業上の利用分野」
本発明は、急峻な海浜や護岸べりに造成するのに好適な
構造を有しかつ自己浄化能力を有する人工池に関する。DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to an artificial pond having a structure suitable for construction on a steep beach or seawall and having a self-purifying ability.
「従来の技術およびその課題」
近年、都市部の港湾は埋め立てが進み、水辺は人工的な
直立護岸で囲われ、産業優先、機能優先の海辺が形成さ
れてきた。これに対して、自然を取り戻し生活に潤いを
与えるために、水に親しめる海浜や人工池を求める社会
的ニーズが日増しに高まっている。``Conventional technology and its challenges'' In recent years, urban ports have been reclaimed, and waterfronts have been surrounded by artificial upright seawalls, creating seashores that prioritize industry and functionality. In response, there is a growing social need for beaches and artificial ponds where people can enjoy water in order to restore nature and enrich their lives.
ところが、護岸ヘリは一般に掘りが深く、海浜や人工池
等を造成するためには、多量の海浜造成材が必要となる
ので急峻な海浜や護岸べりなど水深の深い部分には造成
するのが困難であるといった問題があった。However, seawall helicopters generally dig deep, and in order to create beaches and artificial ponds, a large amount of beach construction material is required, so it is difficult to construct them in deep water areas such as steep beaches and seawalls. There was a problem that.
また、周辺海域を遮り、いわゆる閉鎖性の人工池とする
と、池の水か停滞してしまうとともに、周辺の水質が悪
いと、造成した人工池も汚染されてしまい、水と親しめ
る空間とはならず、都市部の水辺には不適当である問題
があった。In addition, if you block the surrounding sea area and create a so-called closed artificial pond, the water in the pond will become stagnant, and if the surrounding water quality is poor, the artificial pond created will also be contaminated, making it impossible to enjoy a space where you can enjoy the water. First, there was the problem that it was unsuitable for waterside areas in urban areas.
本発明は前記事情に鑑みてなされたものであつて、水深
の深い部分にも造成できるうえ、汚染され難い人工池の
構造を提供することを目的としている。The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide an artificial pond structure that can be constructed even in deep water areas and is less likely to be contaminated.
「課題を解決するための手段」

前記基の開口部に連通ずる通水部と、この通水部上に前
記岸から堰へ向かうにしたがって表面が下降するように
設けられた砂等の海浜造成材とを備え、前記海浜造成材
の堰から離れた表面には、周辺海域の海面位置よりも深
い凹所が形成され、前記通水部は前記凹所に連通されて
いることを特徴としている。"Means for Solving the Problems" The structure of the artificial pond of the present invention is provided in the surrounding sea area at a predetermined distance from the shore such as a seawall or a steep beach, and has an opening that communicates between the surrounding sea area side and the shore side. Weirs with a A water part, and a beach building material such as sand provided on the water passage part so that the surface descends from the shore toward the weir, and on the surface of the beach building material away from the weir, A recess is formed that is deeper than the sea level of the surrounding sea area, and the water passage portion is communicated with the recess.
「作用」
潮の干満によって、周辺海域の水位が上昇すると、海水
は堰の開口部から通水部を通って岸側へ流入する。そし
て、海浜造成材の表面に形成された凹所内の水位と周辺
海域の水位が一致するように凹所内に海水が流入する。``Operation'' When the water level in the surrounding sea area rises due to the ebb and flow of the tide, seawater flows from the opening of the weir to the shore side through the water passage section. Then, seawater flows into the recess so that the water level in the recess formed on the surface of the beach construction material matches the water level in the surrounding sea area.
通水部を通過する海水は、通水部、海浜造成材の各粒子
間隙ないし表面に棲息する微生物や底生生物の働き及び
粒子により濾過効果により、浄化される。Seawater passing through the water passage is purified by the action of microorganisms and benthic organisms living in the gaps between particles or on the surface of the water passage and the beach construction material, and by the filtration effect of the particles.
また、潮の干満によって、周辺海域の水位が下降すると
、凹所内の海水は通水部と堰の開口部を通って周辺海域
側へ流出する。そして、海浜造成材から通水部を経由し
て壜の開口部から流出する海水は、再び生物処理を受け
たあと、周辺海域へ流出させられる。Furthermore, when the water level in the surrounding sea area decreases due to the ebb and flow of the tide, the seawater in the recess flows out into the surrounding sea area through the water flow section and the opening of the weir. The seawater that flows from the beach construction material through the water passage section and out of the opening of the bottle is once again subjected to biological treatment before being discharged into the surrounding sea area.
