Abstract
Description
本発明は舗装道路の側縁部等に埋設されている雨水ますにおいてボウフラが発生するのを防止する手段に関するものである。 The present invention relates to a means for preventing the occurrence of a bow flutter in rainwater buried in a side edge or the like of a paved road.
舗装道路の両側縁部には、降雨時に路面上の雨水を側溝を経て速やかに下水本管に流し込む為の雨水ますが設置されている。路面上を流れる雨水は雨水ますの蓋に設けた流入口から雨水ますに入り、逐次下水本管に流れ込む仕組みになっている。 On both sides of the paved road, rainwater drains are installed to allow the rainwater on the road surface to flow quickly into the sewage mains through the gutters when it rains. Rainwater that flows on the road surface enters the rainwater from the inflow opening provided in the lid of the rainwater, and flows into the sewer main.
雨水ますには雨水だけでなくゴミや土砂も入り込む。それらが全て下水本管に流れ込むのを防止する為、雨水ますの排水管の取り付け位置は雨水ますの底よりも10〜20cm程上にあり、流れ込んだ土砂などを一定量までは雨水ますの中に蓄積できるようになっている。蓄積した土砂などは適宜人力により排除する。 In addition to rainwater, garbage and earth and sand enter the rainwater. In order to prevent all of them from flowing into the sewage mains, the drainage pipe is installed at a position 10 to 20 cm above the bottom of the stormwater, and up to a certain amount of soil and sand that has flowed into the stormwater Can be stored in Accumulated earth and sand will be removed by human power as appropriate.
雨水ますの構造が上述のようなものである事により長期間雨が降らなかった場合を除けば土砂だけでなく雨水も溜まっているのが普通である。 Since the structure of the rainwater is as described above, it is normal that rainwater is collected as well as earth and sand except when it does not rain for a long time.
近年、道路面を流れ有機物を多量に含んだ雨水が溜まった雨水ますの中で多数のボウフラが発生し、それが羽化した蚊による被害が報告されている。 In recent years, a large number of bow flares have been generated in rainwater containing a large amount of organic matter flowing on the road surface, and damage caused by mosquitoes that have emerged has been reported.
雨水ますは道路の両側に数メートルの間隔で設置されているから都市空間にはかなりの数があり、湿地や水溜りのあまり無い都市部や近郊に蚊の大発生が頻発するようになったのはこのためである。 Since rainwater is installed on both sides of the road at intervals of several meters, there are quite a few urban spaces, and mosquitoes frequently occur in urban areas and suburbs with little wetlands and water pools. This is why.
雨水ます中のボウフラ駆除、又は発生防止手段としては次の様なものがある。
▲1▼殺虫剤の水中投入。
▲2▼雨水マスに蚊が入らぬように流入口を防蚊網で覆う。
▲3▼雨水ますの底部を地下浸透式にする。
▲1▼は雨水と共に流失し、効果に持続性が無いから頻繁に実施する必要があり環境汚染の観点からも好ましくない。
▲2▼は路面のゴミや落ち葉により網の目が詰まりやすく豪雨時に路面が冠水することがある。There are the following as a means of exterminating or preventing the generation of bow flares in rainwater.
(1) Insecticide injection into water.
(2) Cover the inlet with a mosquito net so that mosquitoes do not enter the rainwater trout.
(3) Make the bottom of the rainwater mounds underground.
{Circle around (1)} is washed away with rainwater, and since the effect is not sustainable, it is necessary to carry out frequently and is not preferable from the viewpoint of environmental pollution.
In (2), the road surface may be flooded during heavy rain because the nets are easily clogged with dirt and fallen leaves on the road surface.
登録第3103607号
▲3▼はどの場所でも浸透が期待出来るとは限らないし、浸透水によって形成された地下水脈が成長して空洞になり道路の陥没を招く恐れがある。Registration No. 3103607 {circle around (3)} may not be expected to infiltrate everywhere, and the groundwater vein formed by the infiltrated water may grow into a hollow and cause the road to collapse.
多くの蚊は人を刺して不快にさせるばかりでなく伝染病を媒介する事もあるからかの発生防止は人の健康維持の観点から重要な課題である。
以上に述べた従来のボウフラ除去機材について薬剤は簡便であるが持続性がなく、防蚊網はゴミや木の葉による目詰まりがあり、地下浸透式は路盤の沈下などの弊害の多いものであった。 The above-mentioned conventional bowl hula removal equipment is simple but unsustainable, the mosquito net is clogged with garbage and leaves, and the underground penetration type has many harmful effects such as subsidence of the roadbed. .
銅材を水中に入れれば銅イオンの発生によりボウフラが発生しない事は以前から知られた方法であったが、これを確認する為、日本銅センターは(財)日本環境衛生センターに試験を依頼した。その結果は日本銅センターのホームサイトにて公表されており、その効果のある事は周知の事実である。 It has been known for a long time that copper flakes are not generated due to the generation of copper ions when copper is put into water. To confirm this, the Japan Copper Center requested a test from the Japan Environmental Health Center. did. The results are published on the homepage of the Japan Copper Center, and it is a well-known fact that it is effective.
本発明はボウフラの発生防止に有効な市販の工業製品材料の銅板1.5ミリ以下の薄板に浮揚剤を取付ける事により、ボウフラの発生する雨水ます等の水中に於いて常に銅板が垂直状態になり、銅板の両面が雨水の接触有効面積になるようにしたものである。この場合銅板の底部が雨水ますの底に触れても触れなくても良い。 In the present invention, by attaching a flotation agent to a commercially available industrial product material copper plate of 1.5 mm or less, which is effective in preventing the generation of boufra, the copper plate is always in a vertical state in water such as rainwater generated by boufra. In other words, both sides of the copper plate have an effective contact area with rainwater. In this case, the bottom of the copper plate may or may not touch the bottom of the rainwater masu.
浮揚材が無ければ銅板は雨水ますの底に水平に沈む事もあり、銅板の上部が流れ込む土砂などの堆積物に覆われボウフラを死滅させる銅イオンの発生が阻害される。 If there is no levitation material, the copper plate may sink horizontally to the bottom of the rainwater, and the upper part of the copper plate is covered with sediments such as earth and sand that flow into it, preventing the generation of copper ions that kill the bowfra.
本発明が雨水ますの排水口よりも大であれば流出せず、水中に於いて長期に亘ってボウフラ退治に有効である。 If the present invention is larger than the drainage port of rainwater, it will not flow out and will be effective in extinguishing bow flares for a long time in water.
本発明の大きさが、雨水ますの雨水流入口より投入できる大きさであれば重い雨水ますの蓋を都度、開け閉めしなくても設置できるので作業量の減少になる。 If the size of the present invention is such that it can be introduced from the rainwater inlet, it can be installed without opening and closing the heavy rainwater lid each time, thus reducing the amount of work.
18リッターの雨水槽に本発明(20×30×200mmの樹脂発泡材の浮揚材を付けた0.3×180×200mmの銅板)を入れたものと、入れないものを並べ、蚊の発生時期である6月1日より二ヶ月間、屋外に放置した結果、入れない方にはボウフラなどの水中微細生物の発生が見られたが、本発明品を入れた雨水槽にはボウフラの発生は一匹も見られなかった。 The mosquito generation time is arranged with the one that put the present invention (0.3 x 180 x 200 mm copper plate with a resin foam levitation material of 20 x 30 x 200 mm) and the one that can not be put in an 18 liter rainwater tank As a result of being left outdoors for two months from June 1st, the generation of underwater micro-organisms such as boufra was seen in those who could not enter, but the occurrence of boufra in the rainwater tank containing the product of the present invention I didn't see any animals.
本発明は単純な構造であるため簡単に製造が出来、簡単に設置も出来る。また比較的廉価に出来るので前述の様に舗装道路の脇にあまりにも数多くある雨水ますなどに設置するには極めて適切である。また、投入しても殺虫剤のような環境汚染の心配もない。近年。西ナイル熱や鳥インフルエンザ等の感染症を媒介する蚊の発生が世界的に問題になっているが本発明はこれ等の問題を解決する環境対策製品として極めて有用と考えられる。 Since the present invention has a simple structure, it can be easily manufactured and easily installed. Moreover, since it can be made relatively inexpensive, as described above, it is extremely suitable for installation in rainwater drains that are too many beside a paved road. Moreover, even if it is added, there is no concern about environmental pollution like insecticides. recent years. Occurrence of mosquitoes that transmit infectious diseases such as West Nile fever and avian influenza has become a global problem, but the present invention is considered to be extremely useful as an environmental measure product that solves these problems.
