Description
本発明は既設用水路の水位が上下する場合、その水門口に設置水流を目的の水田に導くにあたり、簡単な構造で既設用水路の水位が高いときには水田に水が流入し、低いときには止水して水田水位を自動的に確保、かつ、その周辺からの水漏れしない、土盛りおよびコンクリートのいずれの畦においても簡単に設置・脱着可能で、装置が流失しない長寿命の水田用取水堰に関するものである。 In the present invention, when the water level of the existing canal goes up and down, when the water flow at the water gate is guided to the target paddy field, water flows into the paddy field when the water level of the existing canal is high and the water is stopped when it is low. It relates to a long-life paddy intake weir that automatically secures the water level of the paddy field, does not leak from its surroundings, can be easily installed / removed on both piles and concrete pits, and does not lose its equipment. .
水田に水を供給するため、国内各地毎に共同管理された既設用水路が設置されているが、これら自らの水田に水を供給するためには、従来一般的には図2に示すように、先ず既設用水路内に堰板Ａより低い高さの堰板Ｂを立てることにより、堰板Ａで水路の一部を一時的に止めて水路内に貯水し、それを水田に流すという方法が用いられている。これらの堰板には殆どの場合木板が用いられている。
また、水田の水位を作物の生育や天候等の状況に応じて変更したい場合が往々にして生じる。このような場合、それらを調整するには高さの異なる堰板を準備して取り替えるか、または堰板を予め２段や３段構造にしておき、水位を確保するなどの不便さがあった。さらに木製の堰板の宿命として常に水に接しているので朽ち易く。通常使用数年で更新しなければならない。また、このような堰板では土畦での設置が困難であり、周辺からの水漏れを十分図ることができず、堰板の周辺に土やビニールシートを詰めるなど、土嚢を積んで漏れ防止を図るのが通例である。
In order to supply water to paddy fields, existing irrigation channels jointly managed in various parts of the country have been installed, but in order to supply water to these paddy fields, as shown in Fig. First, a method is used in which a dam plate B having a height lower than the dam plate A is set up in the existing water channel, so that a part of the water channel is temporarily stopped by the dam plate A, and the water is stored in the water channel. It has been. In most cases, a wooden board is used for these barrier plates.
In addition, it is often the case that it is desired to change the water level of paddy fields according to the situation of crop growth, weather, and the like. In such a case, in order to adjust them, there are inconveniences such as preparing and replacing the weir plates with different heights or securing the water level by setting the weir plates in advance in two or three steps. . Furthermore, it is easy to decay because it is always in contact with water as a fate of a wooden dam. It must be renewed after several years of normal use. In addition, it is difficult to install on a dam with such a dam, and it is not possible to sufficiently leak water from the surroundings, and a sandbag is packed around the dam to prevent leakage. It is customary to aim for this.
解決しようとする問題点は、既設用水路の水位は、各地域の水田への水の分配のため日単位で変化することが多いが、水田への給水と水位の確保するために、従来用いられている堰板による方法において、既設用水路の水位の上下による水田への給水は逐次人の手によらなければならないこと、堰板周辺からの水の流入および流出において水漏れ防止が難しいことについて、特に我が国の水田では土畦の場合が多く、土畦への設置・脱着が極めて簡単で、また、コンクリート畦においても簡単に設置および脱着でき、予想以上の増水での装置の流失、水漏れおよび完全な止水がなされ、装置堰板の寿命が使用数年と比較的短いことである。 The problem to be solved is that the water level of the existing canals often changes on a daily basis due to the distribution of water to the paddy fields in each region, but it has been used in the past to secure water supply to the paddy fields and the water level. In the method using the dam plate, water supply to the paddy field by raising and lowering the water level of the existing canal channel must be done by human hands one after another, and it is difficult to prevent water leakage in the inflow and outflow of water from around the dam plate. In particular, paddy fields in Japan often have earthen soil, and are very easy to install and remove from the soil, and can also be easily installed and removed from the concrete soil. The water is completely stopped, and the life of the device weir is relatively short, such as several years of use.
本発明は既設用水路から、導入管にバンドで固定した可撓性管の後部水田側の最後部先端下部に、水位調節用の浮子を取り付けることによって、用水路の水位上昇時には浮子を水が押し下げて水田への水の供給を行い、反対に既設用水路の水位下降時には浮子が水田水位まで上昇して水田からの水の流出を止めることで、既設用水路の水位下降時にも影響されることなく、自動的に水田水位を確保できるようにしたこと、導管にフランジを設けることによる土畦およびコンクリート畦においてもこれにボルトで固定することで本装置の埋設・設置が容易であり、しかもどちらの設置方法においても増水時に装置が流失しないこと、フランジの効果で水田からの漏水の恐れが全く無いこと、水田への水の供給を止めたいとき、浮子の両端に取り付けた紐を上げて可撓性管の位置を上げることで、可撓性管からの水がせき止められ止水を簡単に行うことができること、さらに季節的に水の供給が不要なときには簡単に取り外しできることも最も重要な特徴である。 The present invention attaches a float for adjusting the water level from the existing canal to the bottom end of the rearmost part of the rear side of the flexible pipe fixed to the introduction pipe with a band, so that the water is pushed down when the water level of the canal rises. Water is supplied to the paddy field, and on the contrary, when the water level of the existing canal is lowered, the float rises to the paddy field level and stops the outflow of water from the paddy field. In addition, it was possible to secure the water level of the paddy field, and earthing and concrete fences by providing flanges on the conduits could be easily embedded and installed by fixing them with bolts. However, when the water is increased, the equipment will not be washed away, there is no risk of leakage from the paddy field due to the flange effect, and when you want to stop water supply to the paddy field, Raise the string and raise the position of the flexible tube so that the water from the flexible tube is blocked and water can be easily stopped. In addition, when the water supply is not needed seasonally, it can be easily removed. What can be done is also the most important feature.
本発明の水田用取水堰は次のような効果を有する。
（１）導管直径の範囲内で既設用水路水位の高さに合わせて自動的に水田に給水が可能である。（２）必要とする設置スペースが狭く狭隘な水路内への設置が可能である。（３）我が国内の水田では土畦が一般的であるが、この場合、コンクリート打設の必要なく容易に土畦への設置が可能である、また、コンクリートの畦の場合においても同様に容易に設置が可能である。（４）既設用水路の過大水流時においても本装置が流失しない。（５）導管と可撓性管をバンドで堅固な接続により、ガスケットを用いる事無く水漏れを防ぐことができる。（６）水田からの漏水の恐れが全く無い。（７）水田への水の供給を止めたいとき、浮子の両端に取り付けた紐を上げて可撓性管をつり上げるだけで止水を簡単に行うことができる。（８）構成する材料として軟硬合成樹脂またはステンレスバンド製とすることができるため、装置寿命を極めて長いものとすることができる。
The paddy water intake weir of the present invention has the following effects.
(1) Water can be automatically supplied to the paddy field according to the height of the existing canal water level within the range of the conduit diameter. (2) The installation space required is narrow and can be installed in narrow waterways. (3) Earthen paddies are common in rice paddies in Japan. In this case, it is possible to install them on the earth easily without the need for placing concrete. Easy installation. (4) This device will not be lost even when the existing waterway is overflowing. (5) By firmly connecting the conduit and the flexible tube with a band, water leakage can be prevented without using a gasket. (6) There is no risk of water leakage from paddy fields. (7) When it is desired to stop the supply of water to the paddy field, the water can be stopped simply by raising the strings attached to both ends of the float and lifting the flexible tube. (8) Since it can be made of soft synthetic resin or stainless steel band as the constituent material, the life of the apparatus can be extremely long.
以下、本発明の実施の形態を添付図に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
先ず、既設用水路６から水田へ通ずる導管１を設け、その口径は調整したい水田の水位の上下差を超えるものとし、その先端側（管は用水路から水田に向かうが、本書では既設用水路側を「先端側」、水田側を「後端側」と称する）にバンド３で取り付けた可撓性管２を設け、その最後端下部に浮子４を設ける。既設用水路の水位の上下に合わせて水田への水の供給および停止が行われるが、既設用水路の水位が上昇したときのみ浮子４が水流で沈み水田に水が供給され、既設用水路の水位が下降したとき浮子４が浮上し水田の水の流出を止めるよう装置を設置した。図１に既設用水路６が土畦の場合における本装置での水田へ取水状態での設置を示す。本装置の設置は水田へ通じる導管１を土畦上部位置より下部になるよう水路に対して直角に土中に埋設した。なお導管１に取り付けたフランジ５の上部は、土畦上部位置に比べて同位置かわずかに低い位置となるように埋設した。また、フランジ５の幅は約７cmとした。導管１へのフランジ５の取りけ位置は、導管１の先端側が既設用水路６の水の流れを妨げないよう用水路の水田側壁よりはみ出さないとともに土畦中央部に位置する部分に埋設するものとする。さらに、既設用水路６の水田への水の流入を止める場合、可撓性管２に取り付けた浮子４を引き上げ用紐８で引き上げるが、この紐を土畦に打ち込んだ杭に止める事で水の流入を止めることができた。また、コンクリート畦の場合、この紐をフランジ部分の開孔部分に結束し水の流入を止めることができた。 First, the conduit 1 leading from the existing canal 6 to the paddy field is provided, and the diameter of the conduit 1 exceeds the water level difference of the paddy field to be adjusted, and its tip side (the pipe goes from the canal to the paddy field. A flexible tube 2 attached with a band 3 is provided on the “front end side” and the paddy field side is referred to as “rear end side”, and a float 4 is provided on the lower end of the flexible tube 2. The supply and stop of water to the paddy field is performed according to the upper and lower levels of the existing canal, but only when the water level of the existing canal rises, the float 4 sinks in the water flow and water is supplied to the paddy field, and the water level of the existing canal drops. At that time, a device was installed so that the float 4 surfaced and stopped the outflow of water from the paddy field. FIG. 1 shows an installation in the state of water intake to a paddy field in this apparatus when the existing water channel 6 is earthen. In this installation, the conduit 1 leading to the paddy field was buried in the soil at a right angle to the water channel so as to be lower than the upper position of the soil. In addition, the upper part of the flange 5 attached to the conduit 1 was embedded so as to be slightly lower than the upper part of the earth. The width of the flange 5 was about 7 cm. The flange 5 can be removed from the conduit 1 so that the distal end of the conduit 1 does not protrude from the side wall of the paddy field of the irrigation canal so as not to obstruct the flow of water in the existing canal 6 and is embedded in a portion located in the center of the earth. To do. Furthermore, when stopping the inflow of water into the paddy field of the existing water channel 6, the float 4 attached to the flexible pipe 2 is pulled up by the lifting string 8. I was able to stop the inflow. Moreover, in the case of a concrete cage, this string was tied to the opening part of the flange part, and the inflow of water was able to be stopped.
図３に既設用水路６がコンクリート畦における本装置での水田からの止水状態での設置を示す。本装置の設置位置は土畦の場合とほぼ同様であるが、コンクリート畦１０にボルトを埋設し、導管１に取り付けたフランジ５に開孔してボルトを通しナットで恒久固定した。この場合コンクリートとフランジ５の間にゴムパッキン１１を挟むことで水漏れを防止した。この場合、導管１へのフランジ５の取り付け位置は、土畦への設置と同じである。さらに、既設用水路６の水田への止水も同じ方法であるが、この紐はフランジ５の開孔に結束し水の流入を止めることができた。 FIG. 3 shows an installation in a state where the existing water channel 6 is stopped from the paddy field in this apparatus in a concrete dredge. The installation position of this apparatus was almost the same as that of the earthenware, but a bolt was embedded in the concrete fence 10, a hole was opened in the flange 5 attached to the conduit 1, and the bolt was passed through and fixed permanently with a nut. In this case, water leakage was prevented by sandwiching the rubber packing 11 between the concrete and the flange 5. In this case, the attachment position of the flange 5 to the conduit 1 is the same as the installation on the earthwork. Further, the same method is used to stop water in the existing water channel 6 to the paddy field, but this string can be bound to the opening of the flange 5 to stop the inflow of water.
