本発明は、雨水貯留浸透施設、道路排水施設等の給排水施設に用いられる構造体であって、ます（枡）や槽等を含む構造体に関する。
The present invention relates to a structure used for water supply / drainage facilities such as rainwater storage and penetration facilities, road drainage facilities, etc., and relates to a structure including trout (tan) and tanks.
雨水等は、一般家庭用の小規模設備から、学校、工場等の大型施設において有効利用されている。例えば、特許文献１には、雨水を有効利用する方法として、建物の屋根に降った雨水を貯水タンクに貯めて、これを水洗トイレの水（中水）として利用することが記載されている。
Rainwater etc. are effectively used in small facilities for general households and large facilities such as schools and factories. For example, Patent Document 1 describes, as a method of effectively using rainwater, storing rainwater that has fallen on the roof of a building in a water storage tank and using it as water (medium water) for a flush toilet.
また、特許文献２には、従来無駄に放流されていた公園、校庭等に降った雨水を有効利用し、かつ土地の冠水や洪水の発生を低減させるため、最終貯水槽に集められた雨水の一部を浄化装置に直接導入し、浄化処理して散水やトイレ水として利用したり、一旦大型貯水槽に貯留した水を抽出し、浄化装置において適宜浄化して利用したり、浄化装置で予め雨水を浄化し、浄化した処理水を大容量貯水槽に貯留し、災害時に生活用水として利用する技術が開示されている。
In addition, Patent Document 2 discloses that rainwater collected in the final water tank is used to effectively use rainwater that has been drained in parks, schoolyards, etc., and to reduce flooding and flooding. A part of the water is introduced directly into the purification device and used as sprinkling water or toilet water after being purified, or the water once stored in the large water tank is extracted and appropriately purified in the purification device. A technique for purifying rainwater, storing purified treated water in a large-capacity water storage tank, and using it as domestic water in a disaster is disclosed.
しかし、従来、雨水等を貯留して利用する際には、ますや槽で雨水等が滞留し、腐敗するという問題があった。
However, conventionally, when rainwater is stored and used, there has been a problem that rainwater or the like is retained in the tank and decays.
そこで、例えば、特許文献３に記載の雨水濾過システムでは、濾過器内が雨水に含まれる砂や埃で詰まらないように、濾過器の内筒内に配置された浮子に、短冊状布片等からなる撹拌部材を設け、ポンプによって浮子を上下動させ、雨水を撹拌して圧送し、貯蔵タンクに導いている。
Therefore, for example, in the rainwater filtration system described in Patent Document 3, a strip-shaped cloth piece or the like is placed on a float placed in the inner cylinder of the filter so that the filter is not clogged with sand or dust contained in the rainwater. A stirrer member is provided, the float is moved up and down by a pump, the rainwater is stirred and pumped, and led to the storage tank.
また、特許文献４は、住宅地や造成工事の際に設置され、不純物を含んだ雨水を貯留するのに使用される雨水貯留槽において、貯留した雨水を雨水貯留槽内で撹拌する撹拌装置を備え、また、撹拌装置で撹拌した雨水を雨水貯留槽外へ強制的に排出する排水装置を備え、雨水貯留槽内の内部に不純物が堆積しにくく、流出管から流れ出る雨水中の不純物を少なくできるような雨水貯留槽を提案する。
Moreover, patent document 4 is installed in the case of a residential area or construction work, and in the rainwater storage tank used for storing the rainwater containing an impurity, the stirring apparatus which stirs the stored rainwater in a rainwater storage tank. Equipped with a drainage device that forcibly drains rainwater stirred by a stirrer out of the rainwater storage tank, making it difficult for impurities to accumulate inside the rainwater storage tank and reducing impurities in the rainwater flowing out of the outflow pipe A rainwater storage tank is proposed.
一方、上記のような機械的な雨水等の滞留や腐敗を防止する手段に代えて、プラスチック等からなる雨水貯留槽等の本体の表面に、金属等の抗菌材料を塗布又は吹き付けることで、抗菌・腐敗防止機能を備えた雨水貯留浸透施設等も存在する。さらに、貯留した雨水等の腐敗を防止するため、槽内に薬品を添加する方法も用いられる。
On the other hand, instead of the means for preventing the retention and decay of mechanical rainwater as described above, antibacterial material such as metal is applied or sprayed on the surface of a main body such as a rainwater storage tank made of plastic or the like.・ Rainwater storage and penetration facilities with anti-corruption functions exist. Furthermore, a method of adding chemicals to the tank is also used in order to prevent decay of stored rainwater and the like.
しかし、上記特許文献３及び４に記載の雨水濾過システム等は、濾過器や雨水貯留槽内の雨水を機械的に撹拌して不純物の堆積等を防止するため、撹拌装置等の設置コストや、運転・保守コストが掛かるという問題があった。また、貯留槽等の本体の表面に抗菌材料を塗布又は吹き付けた場合には、塗布層が剥離して抗菌・腐敗防止機能が損なわれたり、表面の抗菌材料が目減りして抗菌・腐敗防止機能が下低し、長期にわたって安定した抗菌・腐敗防止機能を維持することが困難であるという問題があった。さらに、腐敗防止のために薬品を添加する方法では、薬品の添加に要するコスト増に加え、周囲の草木等への環境汚染や、雨水等を再利用したときの安全性に問題があった。
However, the rainwater filtration system and the like described in Patent Documents 3 and 4 are designed to mechanically agitate the rainwater in the filter and the rainwater storage tank to prevent accumulation of impurities. There was a problem of high operating and maintenance costs. In addition, when antibacterial material is applied or sprayed on the surface of a main body such as a storage tank, the coating layer peels off and the antibacterial / anticorruption function is impaired, or the antibacterial material on the surface is diminished and the antibacterial / anticorruption function However, there is a problem that it is difficult to maintain a stable antibacterial and anti-corrosion function over a long period of time. Furthermore, in the method of adding chemicals to prevent spoilage, in addition to the increase in cost required for the addition of chemicals, there are problems in environmental pollution to surrounding vegetation, etc., and safety when reusing rainwater or the like.
そこで、本発明は、上記従来の技術における問題点に鑑みてなされたものであって、機械的装置の設置コスト、薬品コスト等が不要で、環境汚染や再利用時の安全性も損なうことがなく、長期にわたって抗菌・腐敗防止機能を維持しながら継続使用することのできる給排水施設用構造体を提供することを目的とする。
Therefore, the present invention has been made in view of the problems in the above-described conventional technology, and it does not require mechanical equipment installation cost, chemical cost, etc., and environmental pollution and safety during reuse may be impaired. An object of the present invention is to provide a structure for water supply and drainage facilities that can be used continuously while maintaining antibacterial and anti-corrosion functions over a long period of time.

The structure for water supply / drainage facilities may be a structure for rainwater storage and penetration facilities, a structure for road drainage facilities, a water supply / drainage tank, or a water supply / drainage tank.
また、上記給排水施設用構造体において、前記抗菌作用を有する金属を銀とし、銀を担持したプラスチックを、銀イオン溶融混練法により製造した銀含有プラスチックペレットを用いて製造することができる。銀含有プラスチックペレットは、取り扱いが容易であるため、給排水施設用構造体の製造コストの低減に繋がる。
Also, in the structure for water supply and drainage facilities, the metal having antibacterial action can be made of silver, and a plastic carrying silver can be produced using silver-containing plastic pellets produced by a silver ion melt kneading method. Since silver-containing plastic pellets are easy to handle, it leads to a reduction in the manufacturing cost of the structure for water supply and drainage facilities.

次に、具体的な試験方法について説明する。
Next, specific test methods will be described.
試験水として、土を混ぜた雨水（土の濃度は５％）を１リットル作製し、
（Ｎｏ．１）雨水＋土、
（Ｎｏ．２）雨水＋土＋Ａｇピース（１リットルの試験水に対して２個のＡｇピースを投入）、
（Ｎｏ．３）雨水＋菌＋土＋Ａｇピース（１リットルの試験水に対して２２個のＡｇピースを投入）、
の３つのサンプルを用意した。尚、菌は、トイレ（便器）を純水で濡らしたウエスで拭き、そのウエスを、上記（Ｎｏ．３）の雨水に投入し、試験水を製作した。Make 1 liter of rainwater mixed with soil (5% soil concentration) as test water,
(No. 1) rainwater + soil,
(No. 2) rain water + soil + Ag piece (2 Ag pieces are added to 1 liter of test water),
(No. 3) Rainwater + fungus + soil + Ag piece (22 Ag pieces are added to 1 liter of test water),
Three samples were prepared. In addition, the bacteria wiped the toilet (toilet bowl) with a cloth wetted with pure water, and the waste was put into the rain water (No. 3) to prepare test water.
（Ｎｏ．１）雨水＋土、
（Ｎｏ．２）雨水＋土＋Ａｇピース（１リットルの試験水に対して２個のＡｇピースを投入）、
（Ｎｏ．３）雨水＋菌＋土＋Ａｇピース（１リットルの試験水に対して２２個のＡｇピースを投入）、
の３つのサンプルを用意した。尚、菌は、トイレ（便器）を純水で濡らしたウエスで拭き、そのウエスを、上記（Ｎｏ．３）の雨水に投入し、試験水を製作した。
(No. 1) rainwater + soil,
(No. 2) rain water + soil + Ag piece (2 Ag pieces are added to 1 liter of test water),
(No. 3) Rainwater + fungus + soil + Ag piece (22 Ag pieces are added to 1 liter of test water),
Three samples were prepared. In addition, the bacteria wiped the toilet (toilet bowl) with a cloth wetted with pure water, and the waste was put into the rain water (No. 3) to prepare test water.
恒温器を３０℃に設定し、その中に上記Ｎｏ．１～３の試験水を放置し、試験水をほぼ１日毎に純水で洗ったガラス棒にて撹拌した。ビーカー水位の中間層より、ピペットで１００ｍｌ採水した。採水に当たっては、土が沈殿している時に行った。水質検査は、簡易培地を用いて行った。試験結果を表１及び図５に示す。
Set the incubator at 30 ° C and put the above No. The test water of 1 to 3 was allowed to stand, and the test water was stirred with a glass rod washed with pure water almost every day. 100 ml of water was collected with a pipette from the middle layer of the beaker water level. The water was collected when the soil was settled. The water quality test was performed using a simple medium. The test results are shown in Table 1 and FIG.
試験結果より銀には、雨水貯留水について抗菌・腐敗防止作用があることが確認できた。すなわち、Ａｇを入れることにより、（Ｎｏ．２）は、（Ｎｏ．１）に比較して菌の増殖スピードを抑制することができ、（Ｎｏ．３）は菌を減少させることができた。また、今回の試験では、試験水に腐敗臭は感じなかった。
From the test results, it was confirmed that silver has antibacterial and anti-corrosion effects on rainwater storage water. That is, by adding Ag, (No. 2) was able to suppress the growth speed of the bacteria compared to (No. 1), and (No. 3) was able to reduce the bacteria. In this test, the test water did not feel rot odor.
