Description

【0001】
【発明の属する技術分野】
本発明は、配管外周の止水構造に関し、詳しくは、水田等の水耕地や池等の底から鉛直方向に立ち上がるように設置された配管の外周面に沿って水耕地内等の水が地中に流出してしまうことを防止するための止水構造に関する。
【0002】
【従来の技術】
水田の各耕作区内の水位を所定水位に保つための手段として、従来の堰板に代えて水位設定器が用いられるようになってきている。この水位設定器は、鉛直方向に立設した排水縦管の上端に、上下方向にスライド可能な筒体を設けたものであって、筒体の上端の高さを調節することにより、従来よりも確実な水位設定を行えるように形成されている(特開平11−323888号公報参照)。
【0003】
【発明が解決しようとする課題】
ところが、上述の水位設定器は、その構造上、水位設定器の下半部や排水縦管が耕作区の地中に鉛直方向に埋設された状態になっているため、前記筒体を操作する際の振動、車両の走行や人の歩行による振動、耕作区内の作業による振動等によって排水縦管が振動し、この振動が原因で排水縦管外周面と周囲の土砂との間に隙間が発生することがある。このような隙間が発生すると、耕作区内の水(用水)が隙間を伝わって地中深くまでほとんど抵抗もなく流下し、下流側の配管の設置状態や下層の土砂の性状によっては大量の水が流出してしまい、耕作区内の水位が低下してしまうおそれがあった。
【0004】
そこで本発明は、水田耕作区に設置された水位設定器の排水縦管のように、地中に鉛直方向に埋設した配管の外周面を伝わって水が流下することを防止できる配管外周の止水構造を提供することを目的としている。
【0005】
【課題を解決するための手段】
上記目的を達成するため、本発明の配管外周の止水構造は、地中に鉛直方向に埋設した配管外周の止水構造であって、弾性体で形成した止水シートの配管挿通孔の直径を前記配管の外径より小さめに形成し、前記止水シートを、前記配管の地中埋設部の外周面と前記配管挿通孔の内周縁とを水密状態で密着させて水平方向に設置したことを特徴とし、特に、前記配管が、水田に設置された水位設定器に接続される排水縦管であることを特徴としている。
【0006】
【発明の実施の形態】
図は本発明の配管外周の止水構造を水田耕作区の水位設定器に適用した一形態例を示すものであって、図1は水位設定器の設置状態を示す縦断面図、図2は止水シートを設けた排水縦管を接続した状態の水位設定器の縦断面図、図3は同じく斜視図である。
【0007】
まず、水位設定器10は、角筒状の排水枡11と、該排水枡11の底板12に設けた排水口13に接続される鉛直方向の排水縦管14と、排水口13に上下方向に摺動可能に装着された水位設定用の筒体15とにより形成されている。前記筒体15は、水密性と適度な摺動抵抗とを得るためのゴム製シールパッキン16を介して排水口13に取付けられており、底板12に対して任意の高さに保持できるように形成されている。また、筒体15には把手17が設けられており、排水枡11の前面開口両側には、土砂の流入を防止する堰板11aを取付けるための堰板取付部11bが設けられている。
【0008】
なお、水位設定器における各部の形状や材料は任意であり、例えば、排水枡11の形状は、図4の排水枡111に示すように、横断面が半円形状であってもよく、図5の排水枡112に示すように、横断面が矩形状であってもよい。また、排水枡の材質も、合成樹脂やコンクリート等で形成することができる。
【0009】
このように形成された水位設定器10は、図1に示すように、排水枡11に接続した排水縦管14の下端に、排水路18に至る水平乃至下り勾配を有する排水横管19をエルボ19aを介して接続した状態で、水田耕作区20の畦畔21部分や農道部分に設置される。
【0010】
そして、上記水位設定器10を水田耕作区20に設置する際には、耕作区下方の地中に鉛直方向に埋設される配管、すなわち、排水縦管14の外周に止水シート22を水平方向に設置する。
【0011】
止水シート22は、その中心部に配管挿通孔23を有するものであって、この配管挿通孔23に配管を挿入したときに、配管外周面と配管挿通孔23の内周縁とが水密状態で密着するように形成されている。このとき、止水シート22をゴムのような弾性体で形成し、かつ、配管挿通孔23の直径を配管外径より小さめに形成し、配管挿通孔23に配管を挿入する際に止水シート22を引き延ばした状態で行うことにより、配管挿入後の両者の密着を自動的にかつ確実に行うことができる。
【0012】
なお、止水シート22の外周をプラスチックシートやプラスチックフィルムで形成し、配管挿通孔23の付近のみをゴム等の弾性材料で形成することもでき、全体をプラスチックシートやプラスチックフィルムで形成し、配管外周面と配管挿通孔23の内周縁とを別の部材でシールするようにしてもよい。
【0013】
このように、地中に鉛直方向に埋設された排水縦管14の外周に水平方向の止水シート22を設置しておくことにより、排水縦管14に振動や外力が加わって管外周面と周囲の土砂との間に隙間が発生し、この隙間を伝わって水が流下したとしても、止水シート22によって流下する水をせき止めることができる。このとき、せき止められた水が止水シート22の上面に沿って流れようとするが、止水シート22の上面には土圧が作用しており、土砂と止水シート22との間に隙間が発生することはほとんどないので、水が流れたとしてもごく僅かな量である。
【0014】
したがって、排水縦管14と周囲の土砂との間に大きな隙間が発生したとしても、耕作区内の水が外部に大量に流出してしまうことを防止でき、耕作区内の水位を、水位設定器10で設定した水位に確実に維持することができる。これにより、耕作用水の無駄を無くすことができ、肥料や農薬の流出も防止できる。
【0015】
なお、前記止水シート22の大きさは、配管の径や、振動等が加わったときの配管の移動量、止水シート22の埋設深さによって異なるが、止水シート22を大きくし過ぎると、設置時に大きな穴を掘らなければなくなるので、止水性を損なわない程度で小さくしておくことが望ましく、配管外径の2〜4倍、通常は3倍程度が最適である。同様に、止水シート22の埋設深さも、配管径等によって適宜に設定できるが、穴の深さを考慮すると、地面(水底)から20〜50cm程度が最適である。また、止水シート22の平面形状は任意であり、四角形でも円形でもよい。厚みも任意であり、強度と重量とを考慮して決定すればよく、通常は数mm程度が適当である。さらに、止水シート22を設置した排水縦管14とその上方の配管や機器との接続方法も任意であり、例えば本形態例では排水縦管14内に排水口13に繋がる管体を挿入するようにしているが、排水縦管14の上端を上方の配管や機器に挿入するようにしてもよい。
【0016】
【発明の効果】
以上説明したように、本発明の配管外周の止水構造によれば、鉛直方向に埋設した配管外周の周囲に隙間が発生しても、隙間を伝わって水が流下することを確実に防止できる。特に、水田耕作区の水位の設定に用いられる水位設定器に接続した排水縦管部分に適用することにより、耕作区内の用水の流出を防止して耕作区内を所定水位に維持しておくことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a water stop structure on the outer periphery of a pipe, and more specifically, water in the hydroponic land and the like along the outer peripheral surface of a pipe installed so as to rise vertically from the bottom of a hydroponic land such as a paddy field or a pond. It is related with the water stop structure for preventing flowing out inside.
[0002]
[Prior art]
As means for keeping the water level in each cultivation area of paddy fields at a predetermined water level, a water level setting device has been used instead of a conventional weir plate. This water level setter is provided with a cylindrical body slidable in the vertical direction at the upper end of a drainage vertical pipe erected in the vertical direction, and by adjusting the height of the upper end of the cylindrical body, Is formed so that a reliable water level can be set (see Japanese Patent Application Laid-Open No. 11-323888).
[0003]
[Problems to be solved by the invention]
However, the above-described water level setting device operates the cylinder because the lower half of the water level setting device and the vertical drainage pipe are buried in the vertical direction in the ground of the cultivation area. The vertical drainage pipe vibrates due to vibration during driving, vibration due to vehicle running or walking, and vibration due to work in the farming area.This vibration causes a gap between the outer circumference of the vertical drainage pipe and the surrounding earth and sand. May occur. When such a gap occurs, the water in the cultivated area (water) flows through the gap and flows almost deeply into the ground with little resistance. Depending on the installation conditions of the piping on the downstream side and the nature of the underlying soil, a large amount of water May flow out and the water level in the cultivation area may be lowered.
[0004]
Accordingly, the present invention provides a pipe outer peripheral stop that can prevent water from flowing down the outer peripheral surface of a pipe buried in the ground vertically like a drainage vertical pipe of a water level setter installed in a paddy field. The purpose is to provide a water structure.
[0005]
[Means for Solving the Problems]
In order to achieve the above-described object, the water stop structure on the outer periphery of the pipe according to the present invention is a water stop structure on the outer periphery of the pipe buried in the vertical direction in the ground, and the diameter of the pipe insertion hole of the water stop sheet formed of an elastic body. Is formed smaller than the outer diameter of the pipe, and the waterproof sheet is installed in a horizontal direction with the outer peripheral surface of the underground buried portion of the pipe and the inner peripheral edge of the pipe insertion hole in close contact with each other in a watertight state. In particular, the pipe is a drainage vertical pipe connected to a water level setter installed in a paddy field.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows an embodiment in which the water stop structure of the pipe outer periphery of the present invention is applied to a water level setting device in a paddy field cultivation area. FIG. 1 is a longitudinal sectional view showing an installation state of the water level setting device, FIG. FIG. 3 is a perspective view of the water level setting device in a state where a drainage vertical pipe provided with a water stop sheet is connected.
[0007]
First, the water level setting device 10 includes a rectangular tubular drainage basin 11, a vertical drainage pipe 14 connected to a drainage port 13 provided on the bottom plate 12 of the drainage basin 11, and a drainage port 13 in the vertical direction. It is formed by a cylinder 15 for setting the water level that is slidably mounted. The cylindrical body 15 is attached to the drainage port 13 through a rubber seal packing 16 for obtaining water tightness and appropriate sliding resistance so that it can be held at an arbitrary height with respect to the bottom plate 12. Is formed. The cylinder 15 is provided with a handle 17, and on both sides of the front opening of the drainage basin 11 are provided dam plate attachment portions 11 b for attaching dam plates 11 a for preventing inflow of earth and sand.
[0008]
The shape and material of each part in the water level setting device are arbitrary. For example, the shape of the drainage basin 11 may have a semicircular cross section as shown in the drainage basin 111 of FIG. As shown in the drainage basin 112, the cross section may be rectangular. The material of the drainage can also be formed of synthetic resin or concrete.
[0009]
As shown in FIG. 1, the water level setting device 10 formed in this way is configured to elbow a drainage horizontal pipe 19 having a horizontal or downward slope leading to the drainage channel 18 at the lower end of the drainage vertical pipe 14 connected to the drainage basin 11. In the state connected via 19a, it is installed in the shore 21 part and the agricultural road part of the paddy field cultivation area 20. FIG.
[0010]
And when installing the said water level setting device 10 in the paddy field cultivation zone 20, the water stop sheet | seat 22 is horizontally installed in the pipe | tube embed | buried in the vertical direction under the cultivation zone, ie, the outer periphery of the drainage vertical pipe 14. Install in.
[0011]
The water stop sheet 22 has a pipe insertion hole 23 at the center thereof, and when the pipe is inserted into the pipe insertion hole 23, the pipe outer peripheral surface and the inner peripheral edge of the pipe insertion hole 23 are in a watertight state. It is formed to be in close contact. At this time, the water stop sheet 22 is formed of an elastic material such as rubber, and the diameter of the pipe insertion hole 23 is formed smaller than the outer diameter of the pipe, and the water stop sheet is inserted when the pipe is inserted into the pipe insertion hole 23. By carrying out in the state which extended 22, both contact | adherence after piping insertion can be performed automatically and reliably.
[0012]
In addition, the outer periphery of the water stop sheet 22 can be formed of a plastic sheet or a plastic film, and only the vicinity of the pipe insertion hole 23 can be formed of an elastic material such as rubber, or the entire can be formed of a plastic sheet or a plastic film. You may make it seal an outer peripheral surface and the inner periphery of the piping penetration hole 23 with another member.
[0013]
Thus, by installing the horizontal water stop sheet 22 on the outer periphery of the drainage vertical pipe 14 buried in the vertical direction in the ground, vibration and external force are applied to the drainage vertical pipe 14 to Even if a gap occurs between the surrounding earth and sand and water flows down through this gap, the water that flows down can be stopped by the water stop sheet 22. At this time, the dammed water tends to flow along the upper surface of the water-stop sheet 22, but earth pressure acts on the upper surface of the water-stop sheet 22, and there is a gap between the earth and sand and the water-stop sheet 22. Since there is almost no occurrence of water, even if water flows, it is a very small amount.
[0014]
Therefore, even if a large gap occurs between the drainage vertical pipe 14 and the surrounding earth and sand, it is possible to prevent a large amount of water in the cultivation area from flowing out to the outside, and the water level in the cultivation area is set to the water level. The water level set by the vessel 10 can be reliably maintained. Thereby, waste of cultivated water can be eliminated and the outflow of fertilizer and agricultural chemicals can be prevented.
[0015]
In addition, although the magnitude | size of the said water stop sheet 22 changes with the diameter of piping, the moving amount | distance of piping when vibration etc. are added, and the embedding depth of the water stop sheet 22, when the water stop sheet 22 is enlarged too much. Since it is necessary to dig a large hole at the time of installation, it is desirable to make it small so as not to impair the waterstop, and the optimum is 2 to 4 times the outside diameter of the pipe, usually about 3 times. Similarly, the embedding depth of the water stop sheet 22 can also be set as appropriate depending on the pipe diameter or the like, but considering the depth of the hole, about 20 to 50 cm from the ground (water bottom) is optimal. Moreover, the planar shape of the water stop sheet | seat 22 is arbitrary and may be square or circular. The thickness is also arbitrary, and may be determined in consideration of strength and weight. Usually, about several mm is appropriate. Furthermore, the connection method of the drainage vertical pipe 14 in which the water stop sheet | seat 22 was installed, and the piping and apparatus of the upper direction is also arbitrary, For example, the pipe body connected to the drain outlet 13 is inserted in the drainage vertical pipe 14 in this embodiment. However, you may make it insert the upper end of the drainage vertical pipe 14 in upper piping or apparatus.
[0016]
【The invention's effect】
As described above, according to the water stop structure on the outer periphery of the pipe of the present invention, even if a gap is generated around the outer periphery of the pipe embedded in the vertical direction, it is possible to reliably prevent water from flowing down through the gap. . In particular, by applying it to the drainage vertical pipe connected to the water level setting device used to set the water level in the paddy field cultivation area, the outflow of water in the cultivation area is prevented and the cultivation area is maintained at a predetermined water level. be able to.
