Description

本発明は、流路の向きが変化する屈曲部などの液面が上昇する可能性のある箇所において、液体の乱れを整え、溢流を抑えるための整流装置に関する。   The present invention relates to a rectifier for adjusting liquid turbulence and suppressing overflow in a portion where the liquid level may rise, such as a bent portion where the direction of a flow path changes.

排水路などの水路では、時間雨量が多く、雨水の流入が集中した場合、流速が速いために、許容水量内であっても、流路の向きが変化する屈曲部において流れに渦や波動、空気の巻き込みが生じる。このため局所的な液面上昇を引き起し、水路から水が溢れ浸水被害が発生することがある。このようなことは流路幅が急に狭まる箇所においても起こりうるものであり、全国のいたるところで発生している。   In waterways such as drainage channels, there is a lot of hourly rainfall, and when the inflow of rainwater is concentrated, the flow rate is fast. Air entrainment occurs. For this reason, the liquid level rises locally and water overflows from the water channel, which may cause inundation damage. Such a situation can occur even in places where the flow path width suddenly narrows, and has occurred throughout the country.

その対策として、水路全体または水路の要所に流れを減勢するための構造を設けるという提案がなされている(例えば特許文献1など)。
特開2001−3437
As a countermeasure, a proposal has been made to provide a structure for reducing the flow at the entire waterway or at a key point of the waterway (for example, Patent Document 1).
JP2001-3437

しかしながら、上述した水流を減勢する従来の構造は、時間当たりの流量が多い場合には、その構造自体が水流を乱し、渦や波動を生じる原因となりうる。特に水路の屈曲部などにおいては渦や波動、空気の巻き込みが生じやすく、流下しきれない水は上方向に盛り上がり、局所的な液面上昇となる。このような屈曲部での局所的な液面上昇を抑制し、溢流の防止を図る対策が望まれている。   However, the above-described conventional structure for reducing the flow of water can cause the vortex and the wave to disturb the water flow when the flow rate per hour is large. In particular, vortices, waves, and entrainment of air tend to occur at bent portions of water channels, and water that cannot flow down swells upward, resulting in a local rise in liquid level. There is a demand for a measure that suppresses the local rise in the liquid level at the bent portion and prevents overflow.

本発明はかかる問題点に鑑みてなされたもので、その目的は、流路内、特に屈曲部や流路幅が変化する箇所での液面上昇を抑制し、溢流を防止することができる整流装置を提供することにある。   The present invention has been made in view of such problems, and the object thereof is to suppress an increase in liquid level in a flow path, particularly in a portion where a bent portion or a flow path width changes, and to prevent overflow. It is to provide a rectifier.

本発明は、液体流路の向きが水平方向に変化する屈曲部に設けられる整流装置であって、液体流路の底面に対して平行に、かつ上下に所定の間隔をおいて設置される複数の水平板と、複数の水平板を液体流路に固定する固定手段とを備えたものである。 The present invention relates to a rectifier provided in a bent portion in which the direction of a liquid flow path changes in the horizontal direction , and a plurality of the flow rectifiers installed parallel to the bottom surface of the liquid flow path and at a predetermined interval in the vertical direction. And a fixing means for fixing the plurality of horizontal plates to the liquid flow path.

この整流装置では、流量が多くなっても水平板によって整流されると共に液面上昇が抑制される。   In this rectifier, even if the flow rate increases, the flow is rectified by the horizontal plate and the rise in the liquid level is suppressed.

本発明の整流装置では、複数の水平板のうち、最上段以外の水平板については、複数の孔を設けることにより、水の上下の移動を許容する構造としてもよい。   In the rectifying device of the present invention, a horizontal plate other than the uppermost one of the plurality of horizontal plates may be configured to allow a vertical movement of water by providing a plurality of holes.

本発明の整流装置では、また、複数の水平板に垂直に、かつ液体流路に沿って1または複数の垂直板を配置し、横方向の流れを整える構造としてもよい。   In the rectifying device of the present invention, one or a plurality of vertical plates may be arranged perpendicular to the plurality of horizontal plates and along the liquid flow path to regulate the lateral flow.

本発明の整流装置によれば、複数の水平板を流路の向きが水平方向に変化する屈曲部に設置するようにしたので、屈曲部などの箇所での局所的な液面上昇を抑制し、溢流、浸水被害の発生を防止することができる。

According to the rectifying device of the present invention, since the plurality of horizontal plates are installed in the bent portion where the flow path direction changes in the horizontal direction , the local rise in the liquid level at the bent portion or the like is suppressed. , Overflow and inundation damage can be prevented.

以下、本発明の実施の形態について図面を参照して詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

〔第1の実施の形態〕
図1および図2は本発明の第1の実施の形態に係る整流装置1の構成を表したものである。図1は整流装置1を水路2の屈曲部2Aの前後にわたって設置した状態、図2は図1のII−II線での断面構造をそれぞれ表すものである。
[First Embodiment]
1 and 2 show the configuration of the rectifier 1 according to the first embodiment of the present invention. FIG. 1 shows a state in which the rectifying device 1 is installed across the bent portion 2A of the water channel 2, and FIG. 2 shows a cross-sectional structure taken along line II-II in FIG.

この整流装置1は、複数、ここでは3枚の水平板10(10A〜10C)を備えたものである。水平板10A〜10Cは複数の支持部11により一体化されており、これら水平板10A〜10Cおよび支持部11は設置板12によって、例えば水路2の底部に固定されている。複数の水平板10は上下に一定の間隔で水平に配置されると共に設置板12と平行に配設されている。なお、設置板12を設けることなく、水平板10A〜10Cを水路2の側壁に固定するようにしてもよい。なお、ここでは水平板10を水平に設置としているが、多少の傾きがある場合も含むものである。   The rectifying device 1 includes a plurality of, here, three horizontal plates 10 (10A to 10C). The horizontal plates 10 </ b> A to 10 </ b> C are integrated by a plurality of support portions 11, and the horizontal plates 10 </ b> A to 10 </ b> C and the support portion 11 are fixed to the bottom of the water channel 2 by, for example, an installation plate 12. The plurality of horizontal plates 10 are horizontally arranged at regular intervals in the vertical direction and are arranged in parallel with the installation plate 12. The horizontal plates 10 </ b> A to 10 </ b> C may be fixed to the side wall of the water channel 2 without providing the installation plate 12. Here, the horizontal plate 10 is set horizontally, but this includes cases where there is a slight inclination.

整流装置1の高さは、最上部の水平板10Aが水路2の深さに対して底面から例えば8割の位置になるように設定されるが、水路2の上縁と実質的に同じ高さに水平板10Aを設置することがより好ましい。水平板10A〜10Cの幅は、水路2と同じ幅であることが好ましい。水平板10A〜10Cおよび支持部11は、設置板12を介して例えばアンカーボルトなどにより水路2の底部に固定されている。なお、水平板10の数と各段の間隔は、水路2の幅、傾斜、許容水量などにより異なる。   The height of the rectifying device 1 is set so that the uppermost horizontal plate 10A is positioned at, for example, 80% of the depth of the water channel 2 from the bottom surface, but is substantially the same height as the upper edge of the water channel 2. It is more preferable to install the horizontal plate 10A. It is preferable that the horizontal plates 10A to 10C have the same width as the water channel 2. The horizontal plates 10 </ b> A to 10 </ b> C and the support portion 11 are fixed to the bottom portion of the water channel 2 by means of anchor bolts or the like via the installation plate 12. Note that the number of horizontal plates 10 and the intervals between the stages differ depending on the width, inclination, allowable water amount, etc. of the water channel 2.

水平板10は、例えば綱板などの硬質でかつ密度が水のそれより充分大きな材料で構成され、その表面は、水の抵抗とならない形状となっている。なお、水平板10の上流側の端面は、水の抵抗の少ない、例えば鋭角状の形状とすることが好ましい。水平板10A〜10Cのうち最上段以外の水平板10B,10Cには複数の孔が設けられており、これら孔を介して水の圧力を開放すると共に、水の上下移動を許容するようになっている。   The horizontal plate 10 is made of a hard material such as a steel plate and has a density sufficiently higher than that of water, and the surface thereof has a shape that does not become water resistance. In addition, it is preferable that the upstream end surface of the horizontal plate 10 has a low water resistance, for example, an acute angle shape. Among the horizontal plates 10A to 10C, the horizontal plates 10B and 10C other than the uppermost step are provided with a plurality of holes, and the pressure of water is released through these holes and the vertical movement of the water is allowed. ing.

設置板12も水平板10と同じ材質により構成することができるが、水路2の底面に接する側の面は、例えば細かい凹凸などの摩擦の大きな構造とすることが好ましい。なお、整流装置1を固定せずに設置可能とするために、設置板12の下流側端面に水路底面に向けて複数の突起を設け、水路底面との摩擦が大きくなるようにし、整流装置1の滑動を防止するようにしてもよい。また、設置板12は主として水路2の底面に固定するためのものであり、支柱部11を直接水路2の底部に固定する構成とするような場合には、設置板12は不要となる。   The installation plate 12 can also be made of the same material as the horizontal plate 10, but the surface on the side in contact with the bottom surface of the water channel 2 preferably has a structure with large friction such as fine irregularities. In order to allow the rectifying device 1 to be installed without being fixed, a plurality of protrusions are provided on the downstream end surface of the installation plate 12 toward the bottom surface of the water channel so that friction with the bottom surface of the water channel increases, and the rectifying device 1 You may make it prevent sliding of. Further, the installation plate 12 is mainly for fixing to the bottom surface of the water channel 2, and the installation plate 12 is not necessary when the support column 11 is directly fixed to the bottom of the water channel 2.

支持部11も水平板10と同じ材質により構成することができ、例えば円,楕円など水の抵抗が少ない形状を有している。   The support part 11 can also be comprised with the same material as the horizontal board 10, for example, has a shape with little water resistance, such as a circle and an ellipse.

本実施の形態の整流装置1を設置する場合には、水路2の幅、深さ、底面の形状などを予め測定し、屈曲部2Aの前後にわたるように水路2にあった水平板10および支柱部11を作成し、組み立てる。この際、施工性を考慮して、例えば水平板10を図1に示した分割線X1,X2で分割してもよい。すなわち、水平板10を屈曲部2Aの分割線X2で2分し、さらに2分されたそれぞれを分割線X1に沿って水路2の半幅で2分し、それぞれの部品を予め組み立てたのちに設置するものである。   When installing the rectifier 1 according to the present embodiment, the horizontal plate 10 and the support column that are in the water channel 2 are measured in advance such that the width, depth, shape of the bottom surface, and the like of the water channel 2 extend over the bent portion 2A. Create and assemble part 11. At this time, considering the workability, for example, the horizontal plate 10 may be divided by the dividing lines X1 and X2 shown in FIG. That is, the horizontal plate 10 is divided into two at the dividing line X2 of the bent portion 2A, and each of the divided two is further divided into two at the half width of the water channel 2 along the dividing line X1, and each component is assembled after being assembled in advance. To do.

なお、図3に表したように、1枚の水平板10と設置板12とそれらを支える支柱部11により構成される整流装置を複数段積み重ねる構成としてもよい。例えば、整流装置1Aを水路2の底面に設置板12を介して固定し、その上にもう1つの整流装置1Bを積み重ね、下段の整流装置1Aの水平板10に上段の整流装置1Bの設置板12を固定するものである。   In addition, as represented to FIG. 3, it is good also as a structure which piles up the rectifier comprised by the one horizontal plate 10, the installation board 12, and the support | pillar part 11 which supports them in multiple steps. For example, the rectifier 1A is fixed to the bottom surface of the water channel 2 via the installation plate 12, and another rectifier 1B is stacked thereon, and the upper rectifier 1B is installed on the horizontal plate 10 of the lower rectifier 1A. 12 is fixed.

本実施の形態の整流装置では、時間雨量が多く水路2の屈曲部2Aに雨水が集中した場合においても、水平板10によって水の渦や波動が強制的に整えられ、局所的な液面上昇が抑制される。   In the rectifier according to the present embodiment, even when the amount of rainfall is large and the rainwater is concentrated on the bent portion 2A of the water channel 2, the horizontal plate 10 forcibly adjusts the vortex and wave of the water, and the liquid level rises locally. Is suppressed.

このように本実施の形態では、屈曲部2Aの前後にわたって整流装置1を設置するようにしたので、時間当たりの流量が多い場合でも、局所的な液面上昇を抑えることができ、溢流、浸水被害を防止することが可能になる。   Thus, in this embodiment, since the rectifier 1 is installed across the bent portion 2A, even when the flow rate per hour is large, a local increase in liquid level can be suppressed, and overflow, Inundation damage can be prevented.

また、本実施の形態の整流装置1は、水路2の幅や形状に関係なく適合させることが可能であり、既設の水路に容易に設置することできる。   Moreover, the rectifier 1 of this Embodiment can be adapted irrespective of the width | variety and shape of the water channel 2, and can be easily installed in the existing water channel.

以上、第1の実施の形態について説明したが、本発明はこれに限定されるものではなく、種々変形可能である。例えば、整流装置1の流下能力を下げないために、支柱部11の体積および数はできるだけ少なくするようにしてもよく、支柱部11を用いることなく、水平板11を水路2の側壁に直接固定するようにしてもよい。また、図3に示した整流装置1A,1Bにおいても、水平板10と設置板12とを1つの支柱部11で固定するようにしてもよい。   Although the first embodiment has been described above, the present invention is not limited to this and can be variously modified. For example, in order not to reduce the flow-down capability of the rectifying device 1, the volume and number of the support columns 11 may be reduced as much as possible, and the horizontal plate 11 is directly fixed to the side wall of the water channel 2 without using the support columns 11. You may make it do. Further, in the rectifiers 1A and 1B shown in FIG. 3, the horizontal plate 10 and the installation plate 12 may be fixed by a single column portion 11.

〔第2の実施の形態〕
図4は本発明の第2の実施の形態に係る整流装置3の構成を表したものである。本実施の形態は、第1の実施の形態が水平方向に折れ曲がる屈曲部2Aに適用した例であるのに対し、屈曲部2B、すなわち流路底面勾配が流下方向に変化する箇所に整流装置3を適用したものである。
[Second Embodiment]
FIG. 4 shows the configuration of the rectifier 3 according to the second embodiment of the present invention. The present embodiment is an example in which the first embodiment is applied to a bent portion 2A that bends in the horizontal direction, whereas the rectifier 3 is provided at the bent portion 2B, that is, where the flow path bottom surface gradient changes in the flow-down direction. Is applied.

この整流装置3は、複数の水平板10に対して複数の垂直板21を交差するように配置したものであり、垂直板21は水平板10を支持する機能を有すると共に、横方向の整流機能を有している。   This rectifier 3 is arranged so that a plurality of vertical plates 21 intersect with a plurality of horizontal plates 10, and the vertical plate 21 has a function of supporting the horizontal plate 10 and a rectifying function in the lateral direction. have.

本実施の形態においても、第1の実施の形態と同様に、水路2へ多量の雨水が流入した場合、屈曲部2Bにおいては、水平板10および垂直板21によって水の渦や波動が強制的に整えられる。その結果、水は速やかに流下し、これにより局所的な液面上昇を抑え、屈曲部2B付近からの溢流を防止することができる。なお、本実施の形態でも、水路の幅や水路の形状に適合させることが容易であり、既設の水路に設置することできるため施工性が優れている。   Also in the present embodiment, as in the first embodiment, when a large amount of rainwater flows into the water channel 2, water vortices and waves are forced by the horizontal plate 10 and the vertical plate 21 in the bent portion 2B. To be arranged. As a result, water flows down quickly, thereby suppressing a local rise in liquid level and preventing overflow from the vicinity of the bent portion 2B. In this embodiment as well, it is easy to adapt to the width of the water channel and the shape of the water channel, and the workability is excellent because it can be installed in the existing water channel.

なお、上記実施の形態では、本発明の整流装置を水路の屈曲部に適用した例について説明したが、複数の水路が合流する合流部や、図5に示したような、流路幅が狭まるように変化する箇所(幅変化部2C)においても、液面が急激に上昇することがあり、これらの箇所においても本発明は適用可能である。   In the above embodiment, the example in which the rectifier of the present invention is applied to the bent portion of the water channel has been described. However, the flow channel width is narrowed as shown in FIG. The liquid level may rise abruptly even in such a changing place (width changing portion 2C), and the present invention is also applicable to these places.
