Description
本発明は、河川の幅方向に設置して水を堰き止める取水堰に設けた頭首工土砂吐に関するものであり、さらに詳しくは、泥、砂礫が堆積進行した時、手動で横方向にスライドして容易にはめ板を外して堆積した泥、砂礫を除去する頭首工土砂吐に関するものである。 TECHNICAL FIELD The present invention relates to a head construction earth squirt installed in a water intake weir that is installed in the width direction of a river and blocks water, and more specifically, when mud and gravel are accumulated, they slide manually in the lateral direction. mud deposited easily remove the siding and, to a headworks sediment ejection to remove the gravel.
河川より水田などに使用する水を取り入れる方法として、わが国では古くから頭首工により行われている。この頭首工とは、河川の流水を用水路内に引き入れるための諸設備のことであり、中小規模の頭首工は、主として河川の水位を調節するための取水堰と、用水路に引き込む取水口と、取水堰に設けた泥、砂礫を排出する土砂吐などの設備から構成されているのが一般的である。 As a method of taking water to be used for paddy fields from rivers, it has been practiced by heads in Japan for a long time. This head work is a facility for drawing the river water into the irrigation channel, and the medium and small-sized head work is mainly a water intake weir for adjusting the water level of the river and a water intake port for drawing it into the water channel. In general, it is composed of facilities such as mud and sand discharge that discharges gravel in the intake weir.
この頭首工は、利水上の点からは河川より農業用の水を確保すると共に、治水上の点からは台風や大雨の時、河川の流水を安全に流下できるように土砂吐に嵌められたはめ板を外して水量の調整ができるようになっている。台風や大雨の時には、上流から泥、砂礫が流水と一緒に取水堰まで流れ込み、その泥、砂礫が堆積して流水は取水堰を越えて流れるので貯水不能になるばかりでなく、取水堰の上流に設けた取水口それに続く用水路も同様に埋まってしまい貯水不能なる。したがって、はめ板の着脱を必要な時に、簡単にかつ的確にできなければならなかった。 From the point of water use, this head work is secured in the earth and sand so that the water for agriculture can be secured from the river, and from the point of flood control, the river water can flow safely during typhoons and heavy rains. The water volume can be adjusted by removing the fitting plate. During a typhoon or heavy rain, mud and gravel flow from the upstream into the intake weir along with the flowing water, and the mud and gravel accumulate and the flowing water flows beyond the intake weir, making it impossible to store water, and upstream of the intake weir. The water intake that follows it and the irrigation channel that follows it are also buried in the same way, making it impossible to store water. Therefore, it was necessary to be able to easily and accurately attach and detach the fitting plate when necessary.
従来の土砂吐は、土砂吐の両側壁面に断面コ字状の落とし込み溝を設け、その落とし込み溝に上下方向に複数枚のはめ板を落とし込んであり、左右の落し込み溝幅よりはめ板の幅を狭めて作ってあり、余裕を持って落とし込みやすくしてある。 The conventional earth and sand discharger has U-shaped drop grooves on both side walls of the earth and sand discharge, and a plurality of fitting plates are dropped vertically into the drop groove, and the width of the fitting plate is larger than the left and right drop groove widths. It is made with narrowing, and it is easy to drop it with a margin.
しかしながら、はめ板を落とし込む時には問題はなかったが、はめ板を外す時には、はめ板と、はめ板の間にバールの先を入れ、梃子の作用で上部のはめ板を持上げて間隙を作り、鋼線などを通して両端部を結着し、重機などで吊り上げているのが現状であり、水圧に抗して、はめ板を持上げて間隙を作る作業に多大の手数と時間がかかるばかりでなく、重機などが必要となり作業が大掛かりになるという問題点があった。 However, there was no problem when dropping the fitting plate, but when removing the fitting plate, a bar tip was inserted between the fitting plate and the fitting plate, and the upper fitting plate was lifted by the action of the insulator to create a gap. It is the current situation that both ends are bound and lifted with heavy machinery etc., and not only does it take a lot of work and time to lift the fit plate and create a gap against water pressure, but heavy machinery etc. There was a problem that it was necessary and the work was large.
本発明は、上記の問題を解決することを課題として研究開発されたもので、手動ではめ板を横方向にスライドさせることにより、容易に取り外すことができ、簡単に何回も土砂吐をすることができ堰の上流に土砂が溜まらず勿論、用水路にも土砂が入ることがなくなる頭首工土砂吐を提供することを目的とするものである。 The present invention has been researched and developed with the object of solving the above problems, and can be easily removed by manually sliding the fitting plate in the lateral direction, and can easily spill many times. The purpose of the present invention is to provide a head construction earth and sand spill that prevents sediment from entering the irrigation channel as well as sediment from upstream of the weir.
上記の課題を解決し、その目的を達成する手段として、本発明は、河川の幅方向に延在して設置される取水堰に設けた土砂吐の左右両壁面に一対の切り込みガイド溝を縦設し、該切り込みガイド溝は、右側切り込みガイド溝を逆Ｌ字状としてガイド溝の切り込み長さを短くし、左側切り込みガイド溝を横Ｌ字状としてガイド溝の切り込み長さを長くすると共に、末端部をアール状に形成し、その左右切り込みガイド溝に、上面より下面を長くした複数枚の直方体形状のはめ板を嵌合し、該はめ板の右側上面と右側切り込みガイド溝との間に操作杆の先端部が入る隙間部を設けたことを特徴とする頭首工土砂吐を開発し、採用した。 As a means for solving the above-mentioned problems and achieving the object, the present invention is provided with a pair of cut guide grooves vertically formed on the left and right wall surfaces of the earth and sand discharge provided in the intake weir extending in the width direction of the river. The notch guide groove has a right notch guide groove having an inverted L shape and a shorter notch length, and a left notch guide groove having a lateral L shape and a longer notch length. The end portion is formed in a round shape, and a plurality of rectangular parallelepiped fitting plates whose lower surfaces are longer than the upper surface are fitted into the left and right cut guide grooves, and the right upper surface of the fit plate and the right cut guide groove are interposed between them. Developed and adopted a head digger characterized by the provision of a gap where the tip of the operation rod enters.

取水堰１に設けた土砂吐２は、取水堰１の幅方向の所定間隔毎に３個設けられており、土砂吐２の両側壁面２ａ，２ａにＬ字状の切り込みガイド溝８，８を縦設し、その切り込みガイド溝８，８の形状に合致するＬ字状のステンレス製アングル材９，９を両側壁面２ａ，２ａに固着してある。 Three earth and sand discharges 2 provided in the intake weir 1 are provided at predetermined intervals in the width direction of the water intake weir 1, and L-shaped notch guide grooves 8 and 8 are provided on both side walls 2 a and 2 a of the earth and sand discharge 2. L-shaped stainless steel angle members 9 and 9 which are vertically provided and match the shape of the cut guide grooves 8 and 8 are fixed to the side wall surfaces 2a and 2a.
この切り込みガイド溝８，８は、図２，３に示すように、右側切り込みガイド溝８ａを逆Ｌ字状としてガイド溝の切り込み長さを短くし、左側切り込みガイド溝８ｂを横Ｌ字状としてガイド溝の切り込み長さを長くすると共に、末端部をアール状８ｃに形成してある。このように構成された切り込みガイド溝８は、図４に示すように、側面から見れば、下方部から上方部に向かって前方に傾斜するように設けられており、後述のはめ板１０が縦方向に４枚嵌っている。 As shown in FIGS. 2 and 3, the notch guide grooves 8 and 8 have the right notch guide groove 8a as an inverted L shape, the notch length of the guide groove is shortened, and the left notch guide groove 8b as a lateral L shape. The guide groove has a longer cut length and a distal end formed in a round shape 8c. Guide groove 8 cut thus constructed, as shown in FIG. 4, when viewed from the side, is provided so as to be inclined towards front upward portion from the lower portion, the paneling 10 to be described later Four pieces are fitted in the vertical direction.
はめ板１０は、水圧に充分耐え得る強度を持つ比較的分厚くて横方向に長い松板などの直方体形状のもので、図７に示すように、下面の長さＬ1 と、上面の長さＬ 2 の長さを異にしてある。すなわち、上面の長さＬ2 が下面の長さＬ 1 より１０ｍｍ程度短くなっている。 Paneling 10 is of a rectangular shape, such as laterally long pine plate relatively thick with sufficient endure strength water pressure, as shown in FIG. 7, the length L 1 of the lower surface, the upper surface length The length L 2 is different. That is, the length L 2 of the upper surface becomes approximately 10mm shorter than the lower surface of the length L 1.
この直方体形状のはめ板１０を左右の切り込みガイド溝８，８に嵌めると、切り込み長さを短くした逆Ｌ字状の右側切り込みガイド溝８ａと、はめ板１０の右側上面の間に隙間部１１ができることになり、この隙間部１１は、操作杆１２の先端部１３が差し込める隙間部１１になっている。 When this rectangular parallelepiped fitting plate 10 is fitted into the left and right cut guide grooves 8, 8, a gap 11 is formed between the inverted L-shaped right cut guide groove 8 a having a short cut length and the right upper surface of the fit plate 10. This gap portion 11 is a gap portion 11 into which the distal end portion 13 of the operation rod 12 can be inserted.

Yes.
このように構成した本発明の実施の形態の使用態様を説明すると、取水口３の前方にある取水壁１に泥、砂礫が堆積すると、土砂吐２のはめ板１０を外すことにより、堆積された泥、砂礫を排出する。すなわち、切り込み長さを短くした逆Ｌ字状の右側切り込みガイド溝８ａと、はめ板１０の右側上面の間にできた隙間部１１に操作杆１２の先端部１３を差し込んで先端部１３をはめ板１０の側端に当て、操作杆１２の他端を持って矢印Ａ方向に引っ張れば、それに伴ってはめ板１０が横方向にスライドし、右側切り込みガイド溝８ａとの係合が解かれ、はめ板１０が外れることにより堆積する泥、砂礫が排出される。 The usage of the embodiment of the present invention configured as described above will be described. When mud and gravel accumulate on the intake wall 1 in front of the intake port 3, it is deposited by removing the fitting plate 10 of the earth and sand spout 2. The mud and sand gravel are discharged. That is, the distal end portion 13 of the operation rod 12 is inserted into the gap portion 11 formed between the inverted L-shaped right-side notch guide groove 8a having a shorter notch length and the right upper surface of the fitting plate 10, and the distal end portion 13 is fitted. If it is applied to the side end of the plate 10 and pulled in the direction of arrow A while holding the other end of the operating rod 12, the fitting plate 10 slides in the lateral direction, and the engagement with the right notch guide groove 8a is released. Mud and gravel accumulated by the disengagement of the fitting plate 10 are discharged.
このように、操作杆１２の先端部１３を、はめ板１０の右側上面と逆Ｌ字状の右側切り込みガイド溝８ａとの間にできた隙間部１１に引っ掛けて横方向にスライドさせるという極めて簡単な操作ではめ板を外すことができ、従来のはめ板のように上下方向に抜くのと比べて極めて小さな力で取り外すことができ、大人一人で充分に行うことができる至便性がある。 As described above, the tip 13 of the operating rod 12 is extremely easily slid in the lateral direction by being hooked on the gap 11 formed between the right upper surface of the fitting plate 10 and the inverted L-shaped right notch guide groove 8a. With a simple operation, the fitting plate can be removed, and it can be removed with very little force compared to pulling up and down like a conventional fitting plate, which is convenient for an adult alone.
以上、本発明の主要な実施の形態について説明したが、本発明はこれらの実施の形態に限定されるものではなく、発明の目的を達成でき、かつ発明の要旨を逸脱しない範囲内で種々の設計変更が可能であることは当然である。 As mentioned above, although main embodiment of this invention was described, this invention is not limited to these embodiment, In the range which can achieve the objective of invention and does not deviate from the summary of invention, it is various.
