Description

本発明は、水路に堰を形成すべく該水路を横断するように設置され、且つ流体の供給排気による膨張収縮で前記堰が起立倒伏するゴム製袋体により形成されたゴム堰用ゴム製袋体に関する。   The present invention relates to a rubber bag for a rubber weir which is installed so as to cross the water channel so as to form a weir, and is formed by a rubber bag body in which the weir stands up and down by expansion and contraction due to supply and exhaust of fluid. About the body.

従来より、ゴム堰は、ゴム製袋体により形成されており、該ゴム製袋体内に空気等の流体を供給して該ゴム製袋体を膨張起立させることにより、河川又は用水路の取水堰等として利用できるように構成されている。
また、取水堰等として利用しない場合には、前記ゴム製袋体内から流体を排気させて倒伏できるように構成されている。
Conventionally, the rubber weir has been formed by a rubber bag body, and by supplying a fluid such as air into the rubber bag body to inflate and stand up the rubber bag body, the intake weir of a river or a water channel, etc. It is configured to be used as.
Moreover, when not using as a water intake weir etc., it is comprised so that a fluid can be exhausted from the said rubber-made bag body, and it can fall down.

通常、ゴム製袋体の内壁面は平滑に形成されており、ゴム製袋体内部の流体を排気した場合、給排気口に近い部分から収縮が始まり、該給排気口に近い部分から徐々に平滑な内壁面同士の密着が生じてしまい、給排気口近傍が塞がり、それ以上流体が排気されないという欠点がある。   Normally, the inner wall surface of the rubber bag body is formed smoothly, and when the fluid inside the rubber bag body is exhausted, the shrinkage starts from the portion near the air supply / exhaust port, and gradually begins from the portion near the air supply / exhaust port. There is a drawback that the smooth inner wall surfaces are in close contact with each other, the vicinity of the air supply / exhaust port is blocked, and the fluid is not exhausted any more.

また、平滑な内壁面同士が密着したゴム製袋体に流体を供給する際には、平滑な内壁面同士の密着を剥がすために流体に過剰な圧力をかける必要があり、迅速に膨張起立させることが困難となり、更に運転コストがかかるという欠点もある。   In addition, when supplying fluid to the rubber bag body in which the smooth inner wall surfaces are in close contact with each other, it is necessary to apply excessive pressure to the fluid in order to peel off the close contact between the smooth inner wall surfaces, so that the fluid quickly inflates and rises. However, there is a disadvantage that the operation cost is increased.

上記欠点を解決するために、特許文献1には、ゴム堰の内壁面に給排口に連通する溝を設けることが記載されている。   In order to solve the above drawbacks, Patent Document 1 describes that a groove communicating with the supply / discharge port is provided on the inner wall surface of the rubber weir.

しかし、内壁面に溝を設けた場合であっても、該溝を設けた近傍では、流体が供給排気されやすいが、平滑な内壁面の部分では、上記と同様に内壁面同士の密着が生じる虞がある。   However, even when a groove is provided on the inner wall surface, fluid is easily supplied and exhausted in the vicinity where the groove is provided, but the inner wall surface is in close contact with the smooth inner wall surface in the same manner as described above. There is a fear.

そのため、流体の迅速な供給排気ができるゴム堰用のゴム製袋体が要望されている。
特開2003−213658号公報
Therefore, there is a demand for a rubber bag for a rubber weir that can quickly supply and exhaust a fluid.
JP 2003-213658 A

本発明は、上記欠点及び要望に鑑み、流体の迅速な供給排気ができるゴム堰用ゴム製袋体を提供することを課題とする。   An object of the present invention is to provide a rubber bag body for a rubber weir that can quickly supply and exhaust a fluid in view of the above-described drawbacks and demands.

本発明者は、上記課題を解決すべく鋭意研究を重ねた結果、ゴム堰を形成するゴム製袋体の内壁面が平滑であるため、内壁面同士が密着し供給排気に欠点が生じる点に着目し、該内壁面表面に凹又は凸の形状を形成させることで上記課題を解決できることを見いだし、本発明を完成するに至った。   As a result of intensive studies to solve the above problems, the inventor has a smooth inner wall surface of the rubber bag forming the rubber weir. The inventors have paid attention and found that the above-mentioned problems can be solved by forming a concave or convex shape on the inner wall surface, and the present invention has been completed.

かかる構成であれば、ゴム堰用ゴム製袋体の内壁面には凹又は凸形状が形成されているため、ゴム堰用ゴム製袋体内の流体を排気し、該袋体を収縮させても内壁面表面の凹又は凸形状により、内壁面同士の密着が抑制され、空隙部分が残り、流体の排気が迅速に行われる。また、内壁面同士の密着が抑制されているため、迅速にゴム堰用ゴム製袋体内に流体を供給することもできる。
That is, the present invention provides a rubber weir rubber formed by a rubber bag body which is installed so as to cross the water channel so as to form a weir in the water channel, and in which the weir stands up and down by expansion and contraction due to supply and exhaust of fluid.

本発明においては、前記凹又は凸形状が、布目凹凸形状であることが好ましい。
かかる構成であれば、より一層内壁面同士の密着が抑制され、流体の供給排気が迅速に行われる。
In the present invention, the concave or convex shape is preferably a textured uneven shape.
With such a configuration, the close contact between the inner wall surfaces is further suppressed, and the fluid is supplied and exhausted quickly.

本発明のゴム堰用ゴム製袋体においては、該ゴム製袋体の内壁面に凹又は凸形状が形成されているため、内壁面同士の密着を抑制でき、空隙が設けられることで迅速な流体の供給排気ができる。
また、本発明のゴム堰用ゴム製袋体においては、内側ゴム層の表面(内壁面)同士の密着が抑制されているため、流体を供給させて該ゴム堰を起立させる際の供給圧の過剰な上昇が抑制できる。
In the rubber bag body for rubber weirs of the present invention, since the concave or convex shape is formed on the inner wall surface of the rubber bag body, the close contact between the inner wall surfaces can be suppressed, and the gap can be quickly provided. Fluid supply and exhaust can be performed.
Further, in the rubber bag body for the rubber weir of the present invention, since the close contact between the surfaces (inner wall surfaces) of the inner rubber layer is suppressed, the supply pressure at the time of raising the rubber weir by supplying fluid is increased. Excessive rise can be suppressed.

In addition, the said air supply / exhaust port 7 is provided in arbitrary positions on slopes and / or floor surfaces, such as a river and an irrigation channel, and is connected to the fluid supply / exhaust device (not shown).

前記内側ゴム層2の表面(内壁面)の略全面に布目凹凸形状を形成することで、流体(空気等)を排気する際に内壁面同士の密着を実質的にほぼ抑制することができ、前記布目凹凸形状同士が当接することで空隙が形成され流体(空気等)の排気が向上する。
また、排気後に再度流体(空気等)を給気する場合、内壁面同士の密着が実質的に全面に亘り抑制されているため、密着部分を剥がす力が低減され、流体供給時の流体の供給圧を低減でき、運転コストを下げることができ、更にゴム堰用ゴム製袋体1をほぼ均等に膨らまし始めることができる。
尚、河川或いは用水路等の床面とボルト等の締結部材で固定されるゴム堰用ゴム製袋体1の側縁部分には、凹凸形状を設けない方が好ましい。ゴム堰用ゴム製袋体の気密性を保持するためである。
By forming a texture irregularity shape on substantially the entire surface (inner wall surface) of the inner rubber layer 2, it is possible to substantially suppress the close contact between the inner wall surfaces when exhausting fluid (air, etc.), When the textured irregularities come into contact with each other, a gap is formed and the exhaust of fluid (air or the like) is improved.
In addition, when fluid (air, etc.) is supplied again after exhausting, since the close contact between the inner wall surfaces is substantially suppressed over the entire surface, the force to peel off the close contact portion is reduced, and fluid supply during fluid supply The pressure can be reduced, the operating cost can be reduced, and the rubber bag body 1 for rubber weir can be started to inflate almost uniformly.
In addition, it is preferable not to provide uneven | corrugated shape in the side edge part of the rubber bag body 1 for rubber weirs fixed with fastening members, such as a floor surface, such as a river or a water channel, and a volt | bolt.

In this case, it is formed on substantially the entire surface of one surface, and the other surface 2b does not have a textured uneven shape over the entire surface (smooth surface).

一方の面2aを前記布目凹凸形状に、他方の面2bを平滑面とした場合、流体を排気させたとき布目凹凸形状の凸部の頂部と前記平滑面とが当接することで空隙部分が形成され排気が迅速に行われる。
また、流体を供給する場合においては、布目凹凸形状の凸部の頂部と前記平滑面とが当接することで空隙部分が形成されているため、流体供給時の流体の供給圧を低減でき、運転コストを下げることができ、更にゴム堰用ゴム製袋体1をほぼ均等に膨らまし始めることができる。
When one surface 2a has the textured uneven shape and the other surface 2b has a smooth surface, a void portion is formed when the top of the textured uneven surface abuts the smooth surface when the fluid is exhausted. The exhaust is performed quickly.
In addition, when supplying the fluid, since the gap portion is formed by contacting the top of the convex part of the textured uneven shape and the smooth surface, the supply pressure of the fluid at the time of supplying the fluid can be reduced, and the operation is performed. The cost can be reduced, and furthermore, the rubber bag body 1 for rubber weirs can be inflated almost uniformly.
