Description

【０００１】
【発明の属する技術分野】
本発明は、昆虫や小動物などの脱出用スロープを備えた小動物脱出用集水桝に関する。
【０００２】
【従来の技術】
林道等の昆虫や小動物が多数生息する地域に敷設した側溝には昆虫や小動物が誤って入る場合が多いが、側溝内に落ち込んだ小動物は脱出用の足掛かりがないために側溝の外に這い上がることが出来ず、流下水と一緒に側溝内を押し流される。そして、この間に溺れて死亡するか或いは側溝の所望箇所に設けた集水枡内に流れ落ち込み、この集水桝からも這い上がることができずに前記と同様の運命を辿る場合が多い。
【０００３】
このような問題点を解消するため、側溝にあっては、その側壁の一部に膨出部を設けるとゝもに、この膨出部によって形成された空間部に前記側溝の底壁面上から側壁の上端に向け上昇する脱出用のスロープを形成したものや、集水桝にあっては、底壁面上から集水桝の上方開口部に向け上昇する脱出用のスロープを形成したものがある。
【０００４】
【発明が解決しようとする課題】
しかし、側壁の一部に脱出用のスロープを形成するための膨出部を設けた前記側溝にあっては、この膨出部を設置できるだけの広い面積を必要とする。したがって、設置場所に余裕がある場合しかこの側溝を利用することができないし、大きさや構造などの関係でその製造コストが高くなる、といった問題点もある。また、脱出用のスロープを形成した前記従来の集水桝にあっては、その内部の平面積の大きさが限られている関係もあり、前記脱出用のスロープは急勾配に形成せざるを得ず、昆虫や小動物等の体力のない動物にはこの急勾配のスロープを登り切れない、といった問題点がある。
【０００５】
【課題を解決するための手段】
本発明は、上記のような従来の諸問題点を解決した集水用枡を提供することを目的としたものであり、その要旨は、上方が開口する箱型桝体の前後方向中央部の底壁面上に、左側壁と離間した位置からこれと対向する側溝用の嵌合用凹部が形成されていない右側壁に向け次第に上昇する左右方向に延びる誘導用傾斜面部および該誘導用傾斜面部の前後両側に、誘導用傾斜面部から前後両側壁の底壁面上に向け次第に下降する誘導用補助傾斜面部を夫々形成するとゝもに、前記右側壁の内側には前記誘導用傾斜面部の上端部と同一高さで対峙する踊り場と、該踊り場から前後両側壁の上端面に向け次第に上昇する前記誘導用傾斜面部と直交する前後方向に延びる脱出用傾斜面部を夫々形成したことを特徴する小動物脱出用集水枡等にある。
【０００６】
【発明の実施の形態】
以下、本発明を図に示す実施例に基づいて詳細に説明するに、図１において、１は左右方向にやや長い平面視が長方形状の底壁で、該底壁１の四辺から左右の側壁２，３と前後の側壁４，５とが夫々立設しており、これらの各壁１乃至５により全体として上方が開口した箱型状に形成されている。
【０００７】
６は所定幅の誘導用傾斜面部で、前記底壁１の上面１Ａにおける前後方向中央部にあって、前記左側壁２と離間した位置からこれと対向する側溝用の嵌合用凹部が形成されていない右側壁３に向け次第に上昇する傾斜面で形成されており、この誘導用傾斜面部６の左側壁２側における始端６Ａは前記底壁１の上面１Ａと面一の位置にあり、前記右側壁３側における終端６Ｂは後述する踊り場７と同一高さの位置にある。
【０００８】
７は前記右側壁３の内側に形成した水平面からなる踊り場で、該踊り場７は前記誘導用傾斜面部６の終端６Ｂと同一高さで且つこの終端６Ｂと対峙した位置に形成されており、該踊り場７の前後には前記前後の両側壁４，５の上端面に向け次第に上昇する脱出用傾斜面部８，８が夫々形成されている。なお、図中９は前記構成からなる集水桝Ａと連接する側溝１１Ａ用の嵌合用凹部で、該嵌合用凹部９は前記左側壁２及び前後の両側壁４，５の３箇所に夫々形成されている。
【０００９】
図２に示すものは本発明に係る集水桝の第２実施例で、この集水桝Ｂが前記図１に示す第１実施例の集水桝Ａと相違する点は、この集水桝Ｂは２つの構成ブロックで構成されており、この両構成ブロックを組み合わせることで集水桝を形成する構成とした点のみであり、その他の構成は前記第１実施例の集水桝Ａと同じである。
【００１０】
すなわち、前記図２に示す集水桝Ｂは、前記誘導用傾斜面部６を備えた左桝構成ブロックＢ1 と、前記踊り場７と脱出用傾斜面部８を備えた右桝構成ブロックＢ2 とから夫々構成され、該左右の両桝構成ブロックＢ1 ，Ｂ2 をその側方開口部で互いに突き合わせるとゝもに、前後の両側壁４Ａ，５Ａの部分で夫々連結用金具１２及びボルト１３により連結して一体構造としたものである。
【００１１】
また図３に示すものは、本発明に係る集水桝の第３実施例で、この集水桝Ｃと前記図１に示す集水桝Ａとは、誘導用補助傾斜面部１０を更に設けた点で相違するのみであり、その他の構造は同じである。すなわち、この誘導用補助傾斜面部１０は、前記誘導用傾斜面部６の前後両側にそれぞれ設けたもので、該誘導用傾斜面部６から前後の両側壁４，５側における底壁１の上面１Ａまで次第に下降する傾斜面で形成したものである。
【００１２】
更に、図４に示すものは、本発明に係る集水桝の第４実施例で、この集水桝Ｄと前記図３に示す集水桝Ｃとは、集水桝が２つの構成ブロックで形成され、この両構成ブロックを組み合わせることで集水桝Ｄを構成した点で相違するのみであり、その他の構成は前記第３実施例の集水桝Ｃと同じである。
【００１３】
すなわち、図４に示す集水桝Ｄは、前記誘導用傾斜面部６及び誘導用補助傾斜面部１０を備えた左桝構成ブロックＤ1 と、前記踊り場７と脱出用傾斜面部８を備えた右桝構成ブロックＤ2 とから夫々構成され、該左右の両桝構成ブロックＤ1 ，Ｄ2 を側方開口部で互いに突き合わせるとゝもに、連結用金具１２及びボルト１３により連結して一体構造としたものである。
【００１４】
つぎに、前記構成からなる集水桝Ａ乃至Ｄの使用方法並びにその作用を説明すると、図５及び図６に示すように、林道Ｒの両側に左右一対の集水桝Ａ（Ａ乃至Ｄ）を互いに対峙した状態で設置する。この設置の際に、前記踊り場７と脱出用傾斜面部８を備えた側が前記林道Ｒと反対側に位置するようにして集水桝Ａ（Ａ乃至Ｄ）を設置する。なお、図示しないが、この設置した集水桝内に落ち葉，昆虫，小動物等が落下しないように、前記踊り場７と脱出用傾斜面部８を形成した部分を除く集水桝の上方開口部にグレーチングを設置してもよい。
【００１５】
そして、林道Ｒの両側にあっては、前後の両側壁４，５に形成した嵌合用凹部９に、林道Ｒの両側に沿って設置した側溝１１Ａの一端を夫々嵌合し、前記左側壁２に形成した嵌合用凹部９には前記林道Ｒを横切って設置した側溝１１Ｂの一端を夫々嵌合するとゝもに、前記林道Ｒを横切る側溝１１Ｂの開口部にグレーチング１４を設置する。
【００１６】
そこで、昆虫や小動物が集水桝Ａ乃至Ｄ内に誤って入った場合、桝内の水量が少ない場合にあっては、先ず誘導用傾斜面部６や誘導用補助傾斜面部１０を這い上がって踊り場７に辿り着く。この踊り場７で一旦休憩したのち、該踊り場７から前後いずれかの脱出用傾斜面部８を這い上がり、該脱出用傾斜面部８の上端部から林道Ｒとは反対側において前記集水桝Ａ乃至Ｄ外に脱出する。また桝内の水量が多い場合には前記脱出用傾斜面部８を這い上がり、桝外に脱出する。
【００１７】
この脱出に際して、誘導用傾斜面部６が集水桝の底部上面１Ａから開口部上端まで１つの傾斜面であるとその傾斜角がきつくなってしまうが、本発明において前記誘導用傾斜面部６は左右方向に延びており、その終端６Ｂには踊り場７が形成されているとゝもに、この踊り場７から前記誘導用傾斜面部６と直交する前後方向に伸びる脱出用傾斜面部８を形成した構成であるから、前記両傾斜面部６，８の勾配を緩やかに設定することができる。また前記傾斜面を全て粗面に形成することにより、昆虫や小動物でも容易に脱出することができる。
【００１８】
【発明の効果】
本発明に係る小動物脱出用集水桝は、上記のように、上方が開口する箱型桝体の前後方向中央部の底壁面上に、左側壁と離間した位置からこれと対向する側溝用の嵌合用凹部が形成されていない右側壁に向け次第に上昇する左右方向に延びる誘導用傾斜面部および該誘導用傾斜面部の前後両側に、誘導用傾斜面部から前後両側壁の底壁面上に向け次第に下降する誘導用補助傾斜面部を夫々形成するとゝもに、前記右側壁の内側には前記誘導用傾斜面部の上端部と同一高さで対峙する踊り場と、該踊り場から前後両側壁の上端面に向け次第に上昇する前記誘導用傾斜面部と直交する前後方向に延びる脱出用傾斜面部を夫々形成した構成であるから、体力のない昆虫や小動物でも容易に集水桝外に脱出することができる。また、前記誘導用傾斜面部の前後両側に誘導用補助傾斜面部を形成したものにあっては、何れの方向からも前記踊り場に這い上がることができ、昆虫や小動物の脱出がより容易となる。更に、箱型桝体が左桝構成ブロックと右桝構成ブロックとから夫々構成したものにあっては、集水桝が大型の場合であってもその製造，搬送，設置等が容易であるとゝもに、各桝構成ブロックを組み合わせることにより設置場所の条件に自在に対応することができる、といった諸効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a small animal escape drainage basin provided with an escape slope for insects and small animals.
[0002]
[Prior art]
Insects and small animals often mistakenly enter gutters laid in areas where many insects and small animals inhabit, such as forest roads. It cannot be done and it is washed away in the gutter along with the running water. And in many cases, it falls drowned during this time, or it flows down into a water collecting basin provided at a desired location in the side groove, and it often follows the same fate as described above without being able to crawl up from this water collecting basin.
[0003]
In order to solve such a problem, in the side groove, when a bulging portion is provided on a part of the side wall, the space formed by the bulging portion is formed on the bottom wall surface of the side groove.
