【発明の属する技術分野】
本発明は、ゲート設備の運転方法およびゲート設備に関するものである。
【0002】
【従来の技術】
従来より、図3および図4に示すゲート設備(水門)が知られている。このゲート設備は、両端部をゲート1,1の案内溝2,2に摺動自在に嵌合した昇降自在の板状扉体3の一側面にポンプ取付枠6,6を設け、このポンプ取付枠6,6にポンプ群を並設し、各ポンプ7に吸引口9および吐出口10を設け、各吸引口9を扉体3の取水側下部に開口し、各吐出口10からの吐出水が扉体3に当接しないように各吐出口10を取水側と反対側に開口して扉体3を閉鎖した状態において、ポンプ群により取水路側の水位20を下降し得るように構成してある(たとえば、特許文献1参照。)。なお、図Xおよび図Yにおいて、4は巻上機、5はワイヤーロープ、8は原動機、11はフラップ弁(逆止弁)、12は水路床、13は下面受座、14はスクリーン、15は外水位計、16は内水位計、17はポンプ操作室、18は河川の水位、19は水路である。
【0003】
このようなゲート設備では、河川(外水域)の水位18が異常に高くなり、扉体3を閉鎖して水路19を閉鎖した際に、取水路側の水位20が危険水位となり、農作物などが水害の危険にさらされるおそれがある場合には、ポンプ7を始動することによって吸引口9から河川側に排水することで、取水路側の危険水を安全水位まで下降させることができる。また、取水路側の水位20が取水水位より低い場合は扉体を上昇させて水路9を開き、河川側から導水して水位20を上昇させる。

【発明が解決しようとする課題】
しかし、前記従来のゲート設備では、水路19と河川などの外水域との合流点付近、つまり扉体3の外水域側が漂砂の堆積で生成された堆砂Sによって埋まり、扉体(ゲート)3の開閉や水路19から河川への排水に支障を来す場合がある。
【0006】
本発明は、このような事情を考慮してなされたもので、水路と外水域との合流点付近に漂砂の堆積で堆砂が生成されても、この堆砂を確実に除去して、スムーズなゲートの開閉および水路から外水域への排水を得ることができるゲート設備の運転方法およびゲート設備を提供することを目的としている。
【0007】
【課題を解決するための手段】
前記目的を達成するために、請求項1に記載の発明に係るゲート設備の運転方法は、河川、海、湖などの外水域に臨む水路の出口をゲートで開閉するゲート設備において、前記ゲートを閉じて前記水路に貯水し、この貯水をゲートの開放により放流して、ゲート下流側の堆砂を押し流すことを特徴としている。
【0008】
また、前記目的を達成するために、請求項2に記載の発明に係るゲート設備の運転方法は、河川、海、湖などの外水域に臨む水路の出口をゲートで開閉するゲート設備において、前記ゲートを閉じて前記水路に貯水し、この貯水をポンプによりゲート下流側の堆砂に噴流して該堆砂を押し流すことを特徴としている。
【0009】
さらに、前記目的を達成するために、請求項3に記載の発明に係るゲート設備は、河川、海、湖などの外水域に臨む水路の出口に設けた第1ゲートと、この第1ゲートの上流側に設けた第2ゲートと、第1ゲートと第2ゲートの間に設置されて第1ゲート上流側の貯水を該第1ゲート下流側の堆砂に噴流させて堆砂を押し流すポンプ装置とを備えていることを特徴としている。
【0010】
請求項1に記載の発明によれば、水路と河川、海、湖などの外水域との合流点付近、つまりゲートの外水域側(ゲート下流側)に漂砂の堆積によって堆砂が生成されても、ゲートを閉じて水路に貯水したのち、この貯水をゲートの開放により外水域に向けて強力に放流して、前記堆砂を外水域に押し流して除去することができる。
【0011】
請求項2に記載の発明によれば、水路と河川、海、湖などの外水域との合流点付近、つまりゲートの外水域側(ゲート下流側)に漂砂の堆積によって堆砂が生成されても、ゲートを閉じて水路に貯水したのち、この貯水をポンプにより吸い込んで、前記堆砂に向けて噴流させることで、該堆砂を崩壊飛散させながら外水域に押し流して除去することができる。
【0012】
請求項3に記載の発明によれば、水路と河川、海、湖などの外水域との合流点付近、つまり川表ゲートの外水域側(川表ゲート下流側)に漂砂の堆積によって堆砂が生成されても、川表ゲートを閉じて水路に貯水し、この貯水を川表ゲートの開放により外水域に向けて強力に放流して、堆砂を外水域に押し流して除去することができる。また、前記貯水をポンプにより吸い込んで、前記堆砂に向けて噴流させることで、該堆砂を崩壊飛散させながら外水域に押し流して除去することができる。さらに、川表ゲートとポンプゲートの両者を閉じることで、両ゲートの間に貯水槽を形成できるので、たとえポンプゲート上流側の水路が低水位であっても、ポンプゲートの運転によって貯水槽の水位を高めて貯水できるから、この貯水を川表ゲートの開放により外水域に向けて強力に放流して、堆砂を外水域に押し流して除去することができるとともに、貯水槽の貯水をポンプにより吸い込んで、前記堆砂に向けて噴流させることで、該堆砂を崩壊飛散させながら外水域に押し流して除去することができる。また、開放されている川表ゲートから外水域への放流水勢は、ポンプゲートの運転によって増大させることができるので、貯水槽の貯水を川表ゲートの開放により外水域に向けて放流する場合、同時にポンプゲートを運転することで、より一層強力に堆砂を外水域に押し流して除去することができる。
【0013】
【発明の実施の形態】
以下、本発明の一実施の形態を図面に基づいて説明する。図1は平面図、図2は図1の縦断側面図である。これらの図において、ゲート設備は、河川、海、湖などの外水域30に臨む水路31の出口に川表ゲート32が昇降可能(開閉可能)に設けられ、この川表ゲート32の上流側に排水ポンプ33を装備したポンプゲート34が昇降可能(開閉可能)に設けられているとともに、川表ゲート32とポンプゲート34の間にポンプ装置35が設置されている。
【0014】
前記ポンプ装置35は、水中ポンプ35Aと、吐出管または高圧ホース35Bとからなり、吐出管または高圧ホース35Bの吐出口35Cは、水路31と河川、海、湖などの外水域30との合流点付近、つまり川表ゲート32の外水域30側に臨ませてある。なお、図中36は自動除塵機、37は引上装置を示し、水路31を流下してきた木片その他の固形異物を除去する機能を備えている。また、39は堤防または防波堤を示し、水路31の下流部分が貫通している。
【0015】
前記構成において、水路31と外水域30との合流点付近、つまり川表ゲート32の外水域側(ゲート下流側)に漂砂の堆積によって堆砂Sが生成されても、川表ゲート32を閉じて水路31に貯水したのち、この貯水を川表ゲート32の小開度域開放により外水域30に向けて強力に放流することで、堆砂Sを外水域30に押し流して除去することができる。
【0016】
また、川表ゲート32の外水域側(ゲート下流側)に漂砂の堆積によって堆砂Sが生成されても、川表ゲート32を閉じて水路31に貯水したのち、水中ポンプ35Aを運転して、吐出管または高圧ホース35Bの吐出口35Cから前記貯水を堆砂Sに向けてピンポイント的に噴流させることで、該堆砂Sを崩壊飛散させながら外水域30に押し流して除去することができる。
【0017】
さらに、川表ゲート32とポンプゲート34の両者を閉じることで、両ゲート32、34の間に貯水槽38を形成できるので、たとえポンプゲート34上流側の水路31が低水位であっても、ポンプゲート34の運転、つまり装備されている排水ポンプ33の運転によって貯水槽38の水位を高めて貯水できるから、この貯水を川表ゲート32の小開度域開放により外水域30に向けて強力に放流することで、堆砂Sを外水域に押し流して除去することができる。この放流と同時に排水ポンプ33を運転すれば、排水ポンプ33の運転によって川表ゲート32から外水域30への放流水勢を増大させることができるので、より一層強力に堆砂Sを外水域に押し流して除去することができる。また、貯水槽38の貯水は、水中ポンプ35Aを運転して吐出管または高圧ホース35Bの吐出口35Cから堆砂Sに向けてピンポイント的に噴流させることで、該堆砂Sを崩壊飛散させながら外水域30に押し流して除去することができる。
【0018】
このように、水路31と外水域30との合流点付近に漂砂の堆積で堆砂Sが生成されても、川表ゲート32の小開度域開放または水中ポンプ35Aの運転によって、堆砂Sを確実に除去して、スムーズな川表ゲート32の開閉および水路31から外水域30への排水を得ることができる。
【0019】
【発明の効果】
以上説明したように、本発明のゲート設備の運転方法およびゲート設備は構成されているので、以下のような格別の効果を奏する。
【0020】
請求項1に記載の発明によれば、水路と河川、海、湖などの外水域との合流点付近、つまりゲートの外水域側(ゲート下流側)に漂砂の堆積によって堆砂が生成されても、ゲートを閉じて水路に貯水したのち、この貯水をゲートの開放により外水域に向けて強力に放流して、前記堆砂を外水域に押し流して除去することができるので、スムーズなゲートの開閉および水路から外水域への排水を得ることができる。
【0021】
請求項2に記載の発明によれば、水路と河川、海、湖などの外水域との合流点付近、つまりゲートの外水域側(ゲート下流側)に漂砂の堆積によって堆砂が生成されても、ゲートを閉じて水路に貯水したのち、この貯水をポンプにより吸い込んで、前記堆砂に向けて噴流させることで、該堆砂を崩壊飛散させながら外水域に押し流して除去することができるので、スムーズなゲートの開閉および水路から外水域への排水を得ることができる。
【0022】
請求項3に記載の発明によれば、請求項1,請求項2に記載の発明の効果に加えて、川表ゲートとポンプゲートの両者を閉じることで、両ゲートの間に貯水槽を形成できるので、たとえポンプゲート上流側の水路が低水位であっても、ポンプゲートの運転によって貯水槽の水位を高めて貯水できるから、この貯水を川表ゲートの開放により外水域に向けて強力に放流して、堆砂を外水域に押し流して除去することができるとともに、貯水槽の貯水をポンプにより吸い込んで、前記堆砂に向けて噴流させることで、該堆砂を崩壊飛散させながら外水域に押し流して除去することができるので、スムーズなゲートの開閉および水路から外水域への排水を得ることができる。また、開放されている川表ゲートから外水域への放流水勢は、ポンプゲートの運転によって増大させることができるので、貯水槽の貯水を川表ゲートの開放により外水域に向けて放流する場合、同時にポンプゲートを運転することで、より一層強力に堆砂を外水域に押し流して除去することで、スムーズなゲートの開閉および水路から外水域への排水を得ることができる。

In this gate equipment, pump mounting frames 6 and 6 are provided on one side surface of a vertically movable plate-like door body 3 whose both ends are slidably fitted in guide grooves 2 and 2 of gates 1 and 1, respectively. Pump groups are arranged side by side on the frames 6 and 6, each pump 7 is provided with a suction port 9 and a discharge port 10, and each suction port 9 is opened at the lower part of the door 3 on the water intake side, and the discharge water In such a state that the discharge ports 10 are opened on the side opposite to the water supply side and the door body 3 is closed so as not to come into contact with the door body 3, the water level 20 on the water intake passage side can be lowered by the pump group. (For example, see Patent Document 1). In FIGS. X and Y, 4 is a hoisting machine, 5 is a wire rope, 8 is a prime mover, 11 is a flap valve (check valve), 12 is a channel floor, 13 is a bottom seat, 14 is a screen, 15 Is an external water level gauge, 16 is an internal water level gauge, 17 is a pump operation room, 18 is a river water level, and 19 is a water channel.
[0003]
In such a gate facility, the water level 18 of the river (outside water area) becomes abnormally high, and when the door 3 is closed and the waterway 19 is closed, the water level 20 on the intake channel side becomes a dangerous water level, and agricultural crops and the like are flooded. When there is a risk of danger, the dangerous water on the intake channel side can be lowered to the safe water level by starting the pump 7 and draining it from the suction port 9 to the river side. When the water level 20 on the intake channel side is lower than the intake water level, the door body is raised to open the water channel 9, and water is introduced from the river side to raise the water level 20.
[0004]
[Patent Document 1]
JP-B-56-5883 (Figs. 1 and 2)
[0005]
[Problems to be solved by the invention]
However, in the above-mentioned conventional gate equipment, the vicinity of the confluence of the waterway 19 and the outside water area such as a river, that is, the outside water area side of the door body 3 is filled with the sediment S generated by the accumulation of sedimentation, and the door body (gate) 3 is closed. Opening and closing and drainage from the water channel 19 to the river may be hindered.
[0006]
The present invention has been made in consideration of such circumstances, and even if sedimentation is generated by the accumulation of sand drift near the confluence of a waterway and an external water area, the sediment is reliably removed to ensure smoothness. It is an object of the present invention to provide a gate facility operation method and a gate facility capable of opening and closing a gate and draining water from a water channel to an outside water area.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a method of operating a gate facility according to the invention according to claim 1 is a gate facility that opens and closes an outlet of a waterway facing an external water area such as a river, a sea, or a lake. It is characterized in that it is closed and stored in the above-mentioned water channel, and this stored water is discharged by opening the gate, and sediment downstream of the gate is washed away.
[0008]
Further, in order to achieve the above object, a method of operating a gate facility according to the invention according to claim 2, wherein the gate facility opens and closes an outlet of a waterway facing an external water area such as a river, a sea, or a lake, It is characterized in that the gate is closed and water is stored in the water channel, and the stored water is jetted into the sediment downstream of the gate by a pump to flush the sediment.
[0009]
Further, in order to achieve the above object, the gate equipment according to the invention according to claim 3 includes a first gate provided at an outlet of a water channel facing an external water area such as a river, a sea, a lake, and the like. A second gate provided on the upstream side, and a pump device installed between the first gate and the second gate for jetting water stored on the upstream side of the first gate into the sediment downstream of the first gate to flush the sediment. And characterized in that:
[0010]
According to the first aspect of the present invention, sedimentation is generated by sedimentation of sediment near the confluence of a waterway with an external water area such as a river, a sea, or a lake, that is, at an outer water area side (downstream of the gate) of the gate. Also, after the gate is closed and water is stored in the water channel, the stored water can be strongly discharged toward the external water area by opening the gate, and the sediment can be pushed away to the external water area to be removed.
[0011]
According to the second aspect of the present invention, sedimentation is generated by accumulation of sediment near the confluence of a waterway and an external water area such as a river, a sea, or a lake, that is, at an outer water area side (downstream of the gate) of the gate. Also, after the gate is closed and water is stored in the water channel, the stored water is sucked by a pump and jetted toward the sediment, whereby the sediment can be washed away to the outer water area while collapsing and scattering.
[0012]
According to the third aspect of the present invention, sedimentation occurs due to the accumulation of sediment near the junction of the waterway and the external waters such as rivers, seas, and lakes, that is, on the outer waters side of the river surface gate (downstream of the river surface gate). Even if water is generated, the river surface gate is closed and water is stored in the waterway, and the stored water can be strongly discharged to the outer water area by opening the river surface gate, and sediment can be flushed to the outer water area and removed. . In addition, by sucking the stored water by a pump and jetting it toward the sediment, the sediment can be washed away into the outer water area while collapsing and scattered and removed. Furthermore, by closing both the Kawaomote Gate and the pump gate, a water storage tank can be formed between the two gates. Since the water can be stored with the water level raised, this water can be discharged strongly into the outer water area by opening the river surface gate, and sediment can be pushed out to the outer water area to remove it. By sucking it and jetting it toward the sediment, the sediment can be washed away into the outer water area while collapsing and scattered and removed. In addition, since the discharge force from the open front gate to the outside water area can be increased by operating the pump gate, when the water stored in the water storage tank is discharged toward the outside water area by opening the front table gate, By operating the pump gate at the same time, sediment can be even more strongly washed out of the external water area and removed.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings. 1 is a plan view, and FIG. 2 is a vertical sectional side view of FIG. In these figures, the gate equipment is provided at the exit of a waterway 31 facing an external water area 30 such as a river, sea, lake, etc., so that a river surface gate 32 can be moved up and down (openable and closable). A pump gate 34 equipped with a drain pump 33 is provided so as to be able to move up and down (openable and closable), and a pump device 35 is installed between the river gate 32 and the pump gate 34.
[0014]
The pump device 35 includes a submersible pump 35A and a discharge pipe or a high-pressure hose 35B. A discharge port 35C of the discharge pipe or the high-pressure hose 35B is a junction between the water channel 31 and an external water area 30 such as a river, sea, or lake. In the vicinity, that is, facing the outside water area 30 side of the river surface gate 32. In the drawing, reference numeral 36 denotes an automatic dust remover, and 37 denotes a lifting device, which has a function of removing wood chips and other solid foreign substances flowing down the water channel 31. Reference numeral 39 denotes a dike or breakwater, and a downstream portion of the waterway 31 penetrates.
[0015]
In the above configuration, even if sediment S is generated near the confluence of the water channel 31 and the outer water area 30, that is, in the outer water area side (downstream of the gate) of the river surface gate 32, the river surface gate 32 is closed. After the water is stored in the water channel 31, the stored water is strongly discharged toward the external water area 30 by opening the small opening area of the river surface gate 32, so that the sediment S can be removed by flushing to the external water area 30. .
[0016]
Further, even if sediment S is generated due to accumulation of drifting sand on the outer water area side (downstream of the gate) of the river surface gate 32, the river surface gate 32 is closed and the water is stored in the water channel 31, and then the submersible pump 35A is operated. By spraying the stored water from the discharge pipe or the discharge port 35C of the high-pressure hose 35B toward the sediment S in a pinpoint manner, the sediment S can be removed by being flushed into the external water area 30 while collapsing and scattering. .
[0017]
Furthermore, by closing both the river front gate 32 and the pump gate 34, a water storage tank 38 can be formed between the two gates 32, 34. Therefore, even if the water channel 31 on the upstream side of the pump gate 34 has a low water level, The operation of the pump gate 34, that is, the operation of the equipped drain pump 33 allows the water level of the water storage tank 38 to be raised to store the water, so that the water is strongly directed toward the external water area 30 by opening the small opening area of the river surface gate 32. , The sediment S can be removed by flushing it to the outside water area. If the drainage pump 33 is operated at the same time as this discharge, the discharge water force from the river surface gate 32 to the external water area 30 can be increased by the operation of the drainage pump 33, so that the sediment S is more strongly pushed to the external water area. Can be removed. In addition, the water in the water storage tank 38 is operated by operating the submersible pump 35A to jet the sediment S from the discharge pipe or the discharge port 35C of the high-pressure hose 35B toward the sediment S in a pinpoint manner. It can be removed by flushing to the outside water area 30 while doing so.
[0018]
As described above, even if sediment S is generated by accumulation of sand drift near the confluence of the waterway 31 and the outer water area 30, the sediment S is generated by opening the small opening area of the river surface gate 32 or operating the submersible pump 35A. Can be reliably removed, and smooth opening and closing of the river surface gate 32 and drainage from the water channel 31 to the outside water area 30 can be obtained.
[0019]
【The invention's effect】
As described above, since the operation method and the gate equipment of the gate equipment according to the present invention are configured, the following special effects can be obtained.
[0020]
According to the first aspect of the present invention, sedimentation is generated by sedimentation of sediment near the confluence of a waterway with an external water area such as a river, a sea, or a lake, that is, at an outer water area side (downstream of the gate) of the gate. Also, after the gate is closed and the water is stored in the water channel, the stored water is strongly discharged toward the outer water area by opening the gate, and the sediment can be pushed away to the outer water area to be removed, so that the smooth gate can be removed. It is possible to obtain drainage from the open / close and water channel to the outside water area.
[0021]
According to the second aspect of the present invention, sedimentation is generated by accumulation of sediment near the confluence of a waterway and an external water area such as a river, a sea, or a lake, that is, at an outer water area side (downstream of the gate) of the gate. Also, after the gate is closed and the water is stored in the water channel, the stored water is sucked by a pump and jetted toward the sediment, so that the sediment can be washed away into the outer water area while collapsing and scattered. In addition, smooth opening and closing of the gate and drainage from the water channel to the outside water area can be obtained.
[0022]
According to the third aspect of the present invention, in addition to the effects of the first and second aspects of the present invention, a water tank is formed between the two gates by closing both the river surface gate and the pump gate. Even if the water channel on the upstream side of the pump gate is at a low water level, the pump gate can be operated to raise the water level in the water storage tank and store the water. By discharging the sediment, the sediment can be flushed to the external water area to be removed, and the water in the water storage tank is sucked by a pump and jetted toward the sediment, so that the sediment collapses and disperses and is dispersed. Therefore, it is possible to smoothly open and close the gate and drain the water from the water channel to the outside water area. In addition, since the discharge force from the open front gate to the outside water area can be increased by operating the pump gate, when the water stored in the water storage tank is discharged toward the outside water area by opening the front table gate, By operating the pump gate at the same time, the sediment is more strongly pushed to the outside water area and removed, so that smooth opening and closing of the gate and drainage from the water channel to the outside water area can be obtained.
