Description

本発明は、一般土木用、農業用及び工業用水路及び排水路において使用されるU字溝の、コンクリート製枡への接続方法に関する。
The present invention relates to a method of connecting a U-shaped groove used in general civil engineering, agricultural and industrial waterways and drainage channels to a concrete slag .

道路や工事現場においてはU字溝が設置され、雨水や湧水はU字溝内部を通って排水さ
れる。複数の場所に設置されたそれぞれのU字溝内部の流水を集めて排水する場合には、それぞれのU字溝が互いに交差する場所においてコンクリート製枡を設置し、各U字溝内部の流水を集めて一方向に排水させている。又は、それぞれのU字溝は各個に側溝に接続され、それにより各U字溝内部の流水が側溝内に集められて一方向に排出されている。
U字溝をコンクリート製枡に接続する方法としては、従来、一般に、既存のU字溝の一方の端部を、コンクリート製枡の取水口又は排水口に掛けて単に載せ置くという方法が採られている。また、特開2000−240117号公報には、側溝と排水管との接続構造が記載されているが、その接続においては、排水管の端部にフランジが設けられており、このフランジが、側溝の側壁に直接にビスにより固定されている。
U-shaped grooves are installed on roads and construction sites, and rainwater and spring water are drained through the interior of the U-shaped grooves. When collecting and draining the running water inside each U-shaped groove installed in multiple places, install concrete slags in the place where each U-shaped groove intersects each other, and drain the running water inside each U-shaped groove. Collected and drained in one direction. Alternatively, each U-shaped groove is individually connected to the side groove, whereby the running water inside each U-shaped groove is collected in the side groove and discharged in one direction.
As a method for connecting the U-shaped groove to the concrete slag , conventionally, a method is generally employed in which one end of an existing U-shaped groove is simply placed on a water intake or a drain outlet of the concrete slag. ing. Japanese Patent Application Laid-Open No. 2000-240117 describes a connection structure between a side groove and a drain pipe. In this connection, a flange is provided at the end of the drain pipe, and this flange is connected to the side groove. It is directly fixed to the side wall with screws.

特開2000−240117号公報JP 2000-240117 A

しかし、上述したU字溝をコンクリート製枡に接続する従来の方法においては、取水口又は排水口と、これに載せ置かれるU字溝端部との間に幾らか隙間が生じてしまう。したがって、コンクリート製枡の排水口では、U字溝と排水口の接続部分の隙間から排水の一部が漏れ出してしまうことが多い。また、コンクリート製枡の取水口においては、U字溝内部の流水の一部が、コンクリート製枡内に流入せずにU字溝の端部から流れ出てそのままU字溝の底壁などの外側を伝い、さらにU字溝と取水口の接続部分の隙間を通って枡又は側溝外の土壌に漏れ出してしまうという問題点があった。
また、特開2000−240117号公報は、円滑な合流を達成する為に、側溝と排水管との接続構造を検討したものであって、U字溝をコンクリート製枡に接続する場合を何ら想定しておらず、ましてや、その接続部分の隙間からの水漏れに関して一切考慮されてはいない。
かような漏水は、U字溝周囲の土壌を侵食し、ひいてはU字溝の浮上を引き起こすことにつながるので、出来る限り防止されることが望まれる。
However, in the conventional method of connecting the U-shaped groove to the concrete steel plate , some gaps are generated between the water intake or drain port and the end of the U-shaped groove placed on this. Therefore, in the drainage port of concrete iron , a part of drainage often leaks from the gap between the connection part of the U-shaped groove and the drainage port. In addition, in the concrete iron intake, a part of the water flow in the U-shaped groove flows out from the end of the U-shaped groove without flowing into the concrete steel wall and is directly outside the bottom wall of the U-shaped groove. In addition, there is a problem that it leaks into the soil outside the gutter or the side groove through the gap between the connection portion of the U-shaped groove and the water intake.
Japanese Patent Laid-Open No. 2000-240117 has studied a connection structure between a side groove and a drain pipe in order to achieve smooth merging, and assumes no connection between a U-shaped groove and a concrete iron. In addition, no consideration is given to water leakage from the gaps between the connecting portions.
Such water leakage erodes the soil around the U-shaped groove and eventually causes the U-shaped groove to rise, so it is desired to be prevented as much as possible.

本発明者は上記課題に鋭意取り組んだ結果、合成樹脂製U字溝をコンクリート製枡に接続した時に、そのU字溝とコンクリート製枡の接続部分からの水漏れが有効に防止される取付け方法を見出すに至った。
すなわち、本発明は、合成樹脂製U字溝をコンクリート製枡の排水口又は取水口に接続する方法であって、底壁及び左右の側壁において凹条部及び凸条部が交互に長手方向に連続形成された波形構造を有するU字溝の一端側の端部において、その底壁及び左右の側壁より外方に延びる止水フランジ部が一体に成形されてなる合成樹脂製の接続用U字溝を準備し、該止水フランジ部を上記の排水口又は取水口に掛けるようにして、該U字溝を枡に接続し、次いで、該止水フランジ部を排水口又は取水口の周縁壁面に、シール材を介して密着固定してなることを特徴とする、U字溝の枡への接続方法に関する。さらに本発明は、コンクリート製枡の排水口又は取水口に接続するためのU字溝であって、
前記U字溝は、底壁及び側壁において凹条部及び凸条部が交互に長手方向に連続形成された波形構造を有する合成樹脂製U字溝の一端側の端部において、その底壁及び左右の側壁より外方に延びる止水フランジ部が一体に成形されていることを特徴とする、U字溝に

As a result of earnestly working on the above-mentioned problems, the present inventor effectively attached the U-groove made of synthetic resin to the concrete slag , so that water leakage from the connection portion between the U-groove and the concrete slag is effectively prevented. I came to find.
That is, the present invention is a method for connecting a U-groove made of synthetic resin to a drainage port or a water intake port of a concrete slag , wherein the concave and convex portions are alternately in the longitudinal direction on the bottom wall and the left and right side walls. A synthetic resin connection U-shape formed by integrally forming a water-stop flange portion extending outward from the bottom wall and the left and right side walls at one end of the U-shaped groove having a continuously formed corrugated structure. Prepare a groove , connect the U-shaped groove to the trough so that the water stop flange is hung on the drain or intake, and then connect the water stop flange to the peripheral wall of the drain or intake Further, the present invention relates to a method for connecting a U-shaped groove to a ridge , characterized in that the U-shaped groove is fixed in close contact via a sealing material. Furthermore, the present invention is a U-shaped groove for connecting to a drainage port or a water intake port of concrete slag,
The U-shaped groove has a corrugated structure in which concave and convex ridges are alternately formed in the longitudinal direction on the bottom wall and side wall. In the U-shaped groove, the water stop flange portion extending outward from the left and right side walls is integrally formed.

本発明においては、U字溝の一端側の端部において、その底壁及び左右の側壁より外方に延びる止水フランジ部が一体に成形されてなる接続用U字溝を用い、該止水フランジ部をコンクリート製枡の排水口又は取水口に掛けるようにすることにより、U字溝を載せ置く場合と異なって、排水口又は取水口とU字溝端部との隙間が止水フランジ部で覆われ、したがって、特に取水口においては、U字溝内の水が、U字溝の端部からその底壁などの外側を伝って枡又は側溝の外部へと漏れることを防止することが出来る。
その上、本発明は、接続用U字溝の止水フランジ部を、排水口又は取水口の周縁壁面にシール材を介して密着固定する方法をとる為、止水フランジ部と周縁壁面の密着性が高まって隙間を完全に埋め、これにより止水フランジ部と周縁壁面の接続部分からの漏水が有効に防止される。したがって、漏水によるU字溝周囲の土壌の侵食も防止され、もって、U字溝の浮上が防止されるという効果にもつながる。
さらにまた、本発明の方法は、U字溝のコンクリート製枡への接続を、複雑な工程を経る必要がなく、容易に為すことが出来るという利点を有している。
In the present invention, a U-shaped groove for connection formed by integrally forming a water-stop flange portion extending outward from the bottom wall and the left and right side walls at the end portion on one end side of the U-shaped groove is used. Unlike the case where the U-shaped groove is placed, the gap between the drainage port or the water intake and the end of the U-shaped groove is a water-stop flange part, by placing the flange part on the drainage or water intake of the concrete slag. Thus, particularly in the water intake, water in the U-shaped groove can be prevented from leaking from the end of the U-shaped groove to the outside of the trough or the side groove along the bottom wall and the like. .
In addition, the present invention adopts a method in which the water stop flange portion of the connecting U-shaped groove is closely fixed to the peripheral wall surface of the drain port or the water intake port via a sealing material. As a result, the gap is completely filled, thereby effectively preventing water leakage from the connecting portion between the water stop flange portion and the peripheral wall surface. Therefore, the erosion of the soil around the U-shaped groove due to water leakage is also prevented, thereby leading to the effect of preventing the U-shaped groove from rising.
Furthermore, the method of the present invention has the advantage that the connection of the U-shaped groove to the concrete iron can be easily performed without going through a complicated process.

本発明の方法においては、コンクリート製枡の排水口又は取水口に接続され得る接続用U字溝があらかじめ準備される。接続用U字溝には、その一端側の端部において、その底壁及び左右の側壁より外方に延びる止水フランジ部が一体に成形されてなる。止水フランジ部の大きさは、排水口又は取水口の周縁壁面に対して、ボルト及びナット等で有効に固定され得る程度の面積を有していればよい。
使用される接続用U字溝は、その一端側の端部において止水フランジ部が設けられているものであればよく、例えば側壁及び底壁が平坦構造のものや、又は凹凸が長手方向に交互に繰り返された波形構造のもの等が挙げられる。
接続用U字溝の材質としては、合成樹脂、例えばポリエチレン、ポリ塩化ビニル、ポリプロピレン、ポリエチレンテレフタレート、ポリアミド等の硬質合成樹脂が挙げられ、また不飽和ポリエステル等にガラス繊維、炭素繊維、有機繊維などを含有させた繊維強化樹脂も使用され得る。
In the method of the present invention, a connection U-shaped groove that can be connected to a drainage port or a water intake port of a concrete slag is prepared in advance. The connecting U-shaped groove is integrally formed with a water stop flange portion extending outward from the bottom wall and the left and right side walls at the end on one end side. The magnitude | size of a water stop flange part should just have an area of the grade which can be effectively fixed with a volt | bolt, a nut, etc. with respect to the peripheral wall surface of a drain outlet or a water intake.
The connecting U-shaped groove used only needs to be provided with a water stop flange at the end on one end side, for example, the side wall and the bottom wall have a flat structure, or the unevenness in the longitudinal direction. The thing of the waveform structure repeated alternately is mentioned.
Examples of the material of the U-shaped groove for connection include synthetic resins such as hard synthetic resins such as polyethylene, polyvinyl chloride, polypropylene, polyethylene terephthalate and polyamide, and unsaturated polyester and the like such as glass fiber, carbon fiber, and organic fiber. Fiber reinforced resins containing can also be used.

接続用U字溝を準備したら、次にその止水フランジ部を、コンクリート製枡の排水口又は取水口に掛けるようにして該U字溝をコンクリート製枡に接続する。言い換えると、接続用U字溝の端部を、止水フランジ部がコンクリート製枡の排水口と該端部との隙間を、
コンクリート製枡の内側より見て覆うように、コンクリート製枡に接続する。したがって、接続用U字溝をコンクリート製枡に接続した後には、該接続用U字溝の止水フランジ部は、該コンクリート製枡の内側に位置することとなる。
When the U-shaped groove for connection is prepared, the U-shaped groove is then connected to the concrete slag so that the water stop flange portion is hung on the drainage port or the water intake port of the concrete slag . In other words, the end of the connecting U-shaped groove, the water stop flange is the gap between the drainage port of the concrete fence and the end,
So as to cover as viewed from the inside of the concrete squares, connected to the concrete squares. Therefore, after connecting to the concrete mass for connection U-shaped groove, the water stopping flange of the U-shaped groove for the connection, is to be positioned on the inside of the concrete squares.

そして次に、止水フランジ部を、排水口又は取水口の周縁壁面に固定するが、本発明においては、この時、止水フランジ部をシール材を介して排水口又は取水口の周縁壁面に固定する。シール材を介在させることにより、U字溝とコンクリート製枡が互いに密着され、漏水の原因となり得る接続部分の隙間の発生が有効に防止される。止水フランジ部は、例えばボルト及びナット等を用いて排水口又は取水口の周縁壁面に固定される。
使用されるシール材の厚さは、コンクリート製枡の壁面の凹凸の度合いに応じて設定される。
またシール材は、U字溝及びコンクリート製枡の両方に密着して隙間を生じない程度に柔軟性を有し、かつ、水を通さない材質のものであればよく、例えばブチルゴム、ネオプレンゴムやウレタンゴム等のゴムや、又はポリウレタンフォーム等の発泡樹脂等が挙げられる。
And then, the water stop flange is fixed to the peripheral wall of the drain or intake. In the present invention, the water stop flange is attached to the peripheral wall of the drain or intake through the sealing material. Fix it. By interposing the sealing material, the U-shaped groove and the concrete iron are brought into close contact with each other, and the occurrence of a gap in the connecting portion that can cause water leakage is effectively prevented. The water stop flange portion is fixed to the peripheral wall surface of the drain port or the water intake port using, for example, a bolt and a nut.
The thickness of the sealing material used is set according to the degree of unevenness of the wall surface of the concrete iron .
Further, the sealing material may be made of a material that is flexible to such an extent that it does not form a gap by being in close contact with both the U-shaped groove and the concrete slag , and does not allow water to pass. For example, butyl rubber, neoprene rubber, Examples thereof include rubber such as urethane rubber, and foamed resin such as polyurethane foam.

本発明のU字溝の取付けの対象となる枡は、例えばコンクリートから構成されるものであり、その形状ももちろん特に制限はなく、例えば立方体形又は直方体形等が挙げられる。 The ridges to which the U-shaped groove of the present invention is attached are made of concrete , for example, and the shape is not particularly limited, and examples thereof include a cubic shape or a rectangular parallelepiped shape.
