べく数々の改良の試みがなされてきた。2. Description of the Related Art Conventionally, rubber weirs that are arranged across a riverbed and rise and fall by supplying and discharging fluid are well known.
It is heavily used in river use and management. The rubber weir is arranged in a river across a riverbed, and is configured by a rubber bag-like body that rises and falls by supplying and discharging a fluid such as air or water. For example, when it is necessary to store running water in a river, a rubber weir is used to supply a fluid into the bag and expand the bag to raise the bag, and to remove the stored water. Is to discharge the fluid from the bag-like body to make the bag-like body fall down. The rubber weir having such a function has many advantages such as easy construction, easy maintenance and low cost. In addition, the stored water can be easily converted to simple water supply or agricultural water, and can also be used for small-scale power generation.Moreover, it can be used to prevent seawater backflow at the estuary when the tide is high. Helps prevent and is very useful. However, such high value rubber weirs are exposed to the harsh natural environment and are usually arranged at right angles to the water flow, so they are subjected to high water pressure during standing and sometimes have collision with driftwood. In addition, the rubber sheet of the bag-like body that constitutes the rubber weir is susceptible to trauma and destruction, even when it falls down, which is impacted by a boulder from the upstream and is also intentionally destroyed. A number of attempts have been made to achieve rubber dams with high strength and durability to withstand damage.

は大きな課題であった。[0003] In addition, the rubber weir has other problems to be improved. One of the major problems is a negative pressure caused by a water flow that overflows the top of the rubber weir (hereinafter referred to as “overflow water”). This is a problem of the vibration of the rubber dam caused by the vibration. This is because when the depth of overflow water increases, negative pressure is generated in the space between the overflow water and the bag-shaped body of the rubber weir, and the negative pressure area is pressed by flowing water or the atmosphere. The amount of negative pressure fluctuates according to the flow rate of flowing water, and the vibration also changes greatly in response to this, which not only causes a large factor of noise, but also causes fatigue fatigue of the rubber weir, and consequently has a large durability of the rubber weir. It was a big challenge to solve this problem.

る。As described above, in order to prevent vibration of the bag-like body constituting the rubber weir, one plate-like fin or a plurality of fins are conventionally provided near the top of the rubber weir. There was also reported an improved technology that could prevent the vibration of a rubber weir placed to counter overflow water to some extent.However, for example, heavy drifting material such as driftwood was found on the fins at the top of the rubber weir. When a collision occurs, the fins are liable to be destroyed, and the fins and their fixings are splashed by splashing water of the overflowing water, generating noise, and the fins cause the overflowing water to jump up like a fountain, thereby causing the riverbed and the downstream water surface to rise. Slap, layer,
There are also problems such as aggravation of noise, and the vibrations are not sufficiently prevented and the required durability is not satisfied. SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the related art, and sufficiently prevents vibration of a bag-like body constituting a rubber weir against overflow water, and also reduces drifting material such as driftwood. The problem is to prevent the fins from being destroyed even in the event of a collision, and to prevent the secondary noise of the overflow water from being generated by the fins and the metal fittings thereof.

However, in general, the fins can be formed easily, and the fins can be easily and easily installed. In consideration of repairability, economy, and the like, it is more appropriate to use a short dimension rather than providing a long dimension. The planar shape of each fin may be rectangular or square, and may be trapezoidal or trapezoidal in some cases where the bottom (the side joined to the bag-like body) is longer.

の破壊度合いも少ない。The bag-like body constituting the rubber weir of the present invention has one or more net-like fins integrated with it, so that the overflow water of the rubber weir is randomized by the net-like fins. The state where the negative pressure between the bag-like body of a rubber dam and overflow water is small is shown. This can reduce the vibration of the rubber weir,
Further, since the fins are net-like, the impact of the overflow water on the fins can be absorbed, and the secondary vibration and noise can be significantly reduced. As a result, the phenomenon of negative pressure between the bag-shaped body and the overflow water also decreases, and the vibration due to the resonance action of the space in the negative pressure part and the fluctuation of the negative pressure itself due to the flow rate fluctuation of the overflow water also decreases. I do. Then, the overflow water is splashed up by the fins like a fountain, and the generation of noise caused by hitting the riverbed or the downstream water surface is eliminated. If the fin surface is trapezoidal,
The effect of absorbing and reducing the collision impact of overflow water can be amplified. Also, since the fins are net-like, even if drifting objects such as driftwood collide with the fins, the impact due to the drifting object collision can be reduced,
The degree of destruction of the fins due to collision of drifting objects such as conventional plate-like fins is also small.

いて極めて効果のあることがわかった。EXAMPLE A synthetic rubber sheet containing chloroprene rubber as a main raw material was used to post-mold a rubber bag having a total length of 10 m and a circumference of 2 m. Separately, a rectangular net-like fin (mesh: 4 cm × 4 cm) of 30 × 50 cm (thickness 2 cm) was vulcanized and molded from a hard compound rubber material using the same synthetic rubber. Around the top of the above rubber bag-like body, place the above 10 net-like fins into about 2
It was fixed by a fixture at 0 cm intervals (both ends were opened by 1 m). As a comparative example, a plate-shaped rubber fin having the same dimensions was used instead of a mesh (conventional example). The obtained finned bag was fixed to a riverbed for 10 days so as to resist a water flow of a water flow of 30 cm / sec, and the frequency and noise after a predetermined number of days were investigated. The results are shown in the table below. [Note] *: The frequency is counted by a vibration measuring device ***: The noise is the running water noise According to the above experiment, compared to the conventional non-meshed fin,
It has been found that the mesh fins of the present invention are extremely effective in preventing vibration and noise.
