Abstract

PROBLEM TO BE SOLVED: To provide a self power-generating type water leakage detector of an underground facility capable of being activated by detection of a water leakage at an underground facility to be detected.SOLUTION: A self power-generating type water leakage detector of an underground facility comprises: a self power-generating type water leakage detection sensor 11 generating electric power when a water leakage occurs at an underground facility; and a display device 15 for displaying the occurrence of a water leakage 3 on the basis of a power generation voltage or generation current from the self power-generating type water leakage detection sensor 11.

Description

本発明は、地下施設の自己発電型漏水検知装置に関するものである。   The present invention relates to a self-powered water leakage detection device for underground facilities.

電池は通常、二つの電極と、これらの電極に接する電解質から構成され、電極は電子伝導性を、電解質はイオン伝導性をもつ必要がある。液体の電解質は水などの極性溶媒に塩を溶解した溶液（電解液）とする場合が多い（下記非特許文献１参照）。
ところで、供用中の鉄道駅や地下歩道などの地下施設で漏水が発生すると、利用者への滴水が問題となる。また、漏水は地下施設としてのトンネルなどの鉄筋コンクリート構造物では、鉄筋腐食やコンクリートの劣化などの変状を誘発する危険があり、長期間、対策を怠ると耐力低下につながる可能性がある。 A battery is usually composed of two electrodes and an electrolyte in contact with these electrodes. The electrode needs to have electronic conductivity, and the electrolyte needs to have ionic conductivity. In many cases, the liquid electrolyte is a solution (electrolytic solution) in which a salt is dissolved in a polar solvent such as water (see Non-Patent Document 1 below).
By the way, when water leaks in underground facilities such as railway stations and underground sidewalks in service, dripping water to users becomes a problem. In addition, leakage of reinforced concrete structures such as tunnels as underground facilities may cause deformation such as rebar corrosion and deterioration of concrete, and neglecting measures for a long period of time may lead to a decrease in yield strength.

そこで、電気的な手法を用いて漏水を検知するシステム（例えば、下記特許文献１参照）が構築されているが、これは常時、電気を必要とする手段である。そのため、メンテナンス周期が電源交換周期の影響を受けてしまう。また、測定データをその情報をトンネル外部に伝達する手段を含んでいないため、その集約までを行うシステムとなっていない。
なお、後述する本発明とは異なるが、ボルタ電池と同様の化学反応を利用したセンサがあり、この反応を利用した水電池（例えば、下記特許文献２参照）に関する技術は多く存在している。しかし、これらは、電池としての技術であり、その性能向上を図るために、構造や材料を規定するものであり、漏水検知センサを有する漏水検知装置として使用する本発明とは異なるものである。 In view of this, a system for detecting water leakage using an electrical technique (see, for example, Patent Document 1 below) has been constructed, but this is a means that always requires electricity. Therefore, the maintenance cycle is affected by the power supply replacement cycle. In addition, since it does not include means for transmitting the measurement data to the outside of the tunnel, it is not a system that performs the aggregation.
Although different from the present invention described later, there is a sensor using a chemical reaction similar to that of a voltaic battery, and there are many techniques related to a water battery (for example, see Patent Document 2 below) using this reaction. However, these are technologies as a battery, and in order to improve the performance, the structure and material are defined, and are different from the present invention used as a water leakage detection device having a water leakage detection sensor.

上記したように、鉄道駅や地下歩道などの地下施設での漏水は、利用者への影響が早い時期に顕在化するため、早期にその発生を検知する必要がある。また、地下施設としてのトンネル区間、特に、鉄道トンネルでは、維持管理作業の時間的制約からメンテナンス周期の長さが重要となるが、既存の手法は、搭載した電源の交換期間がその周期の制約となる場合が多い。   As described above, water leakage in underground facilities such as railway stations and underground sidewalks manifests in an early stage when the impact on the user is early, so it is necessary to detect the occurrence at an early stage. In addition, in the tunnel section as an underground facility, especially in railway tunnels, the length of the maintenance cycle is important due to the time constraints of maintenance work, but the existing method is limited by the replacement period of the installed power supply. In many cases.

本発明の地下施設の自己発電型漏水検知装置は、地下施設の漏水を受けて発電する自己発電型漏水検知センサと、この自己発電型漏水検知センサからの発電電圧あるいは発生電流に基づいて漏水が生じたことを表示する表示装置とを具備する。   The self-generated water leakage detection device for an underground facility according to the present invention includes a self-generated water leakage detection sensor that generates electric power in response to leakage from the underground facility, and leaks based on the generated voltage or generated current from the self-generated water leakage detection sensor. And a display device for displaying the occurrence.

以下、本発明の実施の形態について詳細に説明する。
図１は本発明に係る地下施設の自己発電型漏水検知装置の模式図である。ここでは地下施設としてトンネルを挙げて説明する。
この図において、１は地下施設としてのトンネル、２はトンネル１のひび割れ、３はひび割れ２より洩れる漏水、１１は自己発電型漏水検知センサ、１２は漏水３を溜める容器、１３，１４は容器１２の内部に配置されて漏水３を検知するイオン化傾向の異なる電極、１３Ａ，１４Ａは電極１３，１４のリード線、１５は表示装置である。 Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 is a schematic diagram of a self-power-generation type water leakage detection device for an underground facility according to the present invention. Here, a tunnel will be described as an underground facility.
In this figure, 1 is a tunnel as an underground facility, 2 is a crack of tunnel 1, 3 is a leak from the crack 2, 11 is a self-power generation type leak detection sensor, 12 is a container for storing the leak 3, and 13 and 14 are containers 12. The electrodes 13A, 14A are lead wires of the electrodes 13, 14 and 15 is a display device.

この自己発電型漏水検知センサ１１は、漏水３を受ける容器１２を備え、この容器１２の内部には、イオン化傾向の異なる電極１３と１４が対向して配置されている。そこで、容器１２が漏水３を受けると、その漏水３が電解液として振る舞い、電極１３と１４とのイオン化傾向の差によって電池としての機能を得る。本発明の自己発電型漏水検知装置は、イオン化傾向の異なる電極１３と１４が漏水３と接して電池として機能することで、これを電源として本発明の自己発電型漏水検知センサ１１が起動する。表示装置１５はリード線１３Ａ，１４Ａを介して電極１３，１４と接続されているので、自己発電型漏水検知センサ１１の起動と連動して、漏水３が生じていることを表示装置１５で表示する。特に、本発明では、トンネルなどの地下施設の漏水には、色々な化学物質が溶け込み、電池の電解液として好適である点に着目している。   This self-power generation type water leakage detection sensor 11 includes a container 12 that receives the water leakage 3, and electrodes 13 and 14 having different ionization tendencies are arranged inside the container 12 so as to face each other. Therefore, when the container 12 receives the water leak 3, the water leak 3 behaves as an electrolytic solution, and a battery function is obtained by the difference in ionization tendency between the electrodes 13 and 14. In the self-powered water leakage detection device of the present invention, the electrodes 13 and 14 having different ionization tendency are in contact with the water leakage 3 and function as a battery. Since the display device 15 is connected to the electrodes 13 and 14 via the lead wires 13A and 14A, the display device 15 displays that the water leakage 3 has occurred in conjunction with the activation of the self-power generation type water leakage detection sensor 11. To do. In particular, in the present invention, attention is paid to the fact that various chemical substances are dissolved in the leakage of underground facilities such as tunnels and are suitable as an electrolyte for batteries.

このように、本発明によれば、検知の対象となる漏水が容器に溜まると、その漏水をボルタ電池（２個の異種金属の電極を、それらの一方又は両方に化学的に作用する溶液に浸した構成の電圧発生用の一次電池）の電解質溶液として自己発電を行うようにしたので、電源の交換周期に作用されず、トンネルのメンテナンス周期の長期化を図ることができる。特に、漏水が海岸地方の塩分を含んだ海水や山岳地方の酸性の温泉水であるような場合には、トンネルの鉄筋コンクリート構造物に対して、鉄筋腐食などの変状を誘発する危険があるのに対して、本発明の自己発電型漏水検知センサの電圧発生が顕著であり、その漏水の早期発見に寄与することができる。   As described above, according to the present invention, when water leakage to be detected accumulates in the container, the water leakage is converted into a voltaic cell (two different metal electrodes are applied to a solution that chemically acts on one or both of them). Since self-power generation is performed as an electrolyte solution of a primary battery for voltage generation in a soaked configuration, the tunnel maintenance cycle can be prolonged without being affected by the power supply replacement cycle. In particular, when the water leakage is salty seawater in the coastal region or acidic hot spring water in the mountainous region, there is a risk of inducing deformation such as rebar corrosion to the reinforced concrete structure of the tunnel. On the other hand, the voltage generation of the self-power generation type water leakage detection sensor of the present invention is remarkable, which can contribute to early detection of the water leakage.

次に、本発明に係る地下施設の自己発電型漏水検知センサの設置位置について説明する。
トンネルでは水密性に関して相対的な弱点箇所で漏水が生じる。それらを具体的に列挙すると、（１）ひび割れ部、（２）打設境界部（目地部）、（３）新設躯体と既設躯体の接合部（拡幅工事などが行われた箇所）、（４）シールドトンネルのセグメント継手部、（５）特に、上記で漏水のあとが認められる箇所などが挙げられる。このような漏水発生の危険性が高い箇所に予め本発明の自己発電型漏水検知装置を設置することで、漏水検知を行う。 Next, the installation position of the self-power generation type water leakage detection sensor in the underground facility according to the present invention will be described.
In the tunnel, water leakage occurs at the relative weak points in terms of water tightness. These are specifically listed: (1) cracked part, (2) casting boundary part (joint part), (3) joint part of newly installed frame and existing frame (location where widening work etc. were performed), (4 ) Segment joint part of shield tunnel, (5) In particular, the place where the above after water leakage is recognized. Water leakage detection is performed by installing the self-power generation type water leakage detection device of the present invention in advance at a location where such a risk of water leakage is high.

また、防水シート周辺や導水樋では、漏水が集まることから、本発明の自己発電型漏水検知装置の設置候補箇所とすることが望ましい。例えば、防水シート下端に本発明の自己発電型漏水検知装置を設置することで、漏水発生を検知することができる。
次に、本発明に係る自己発電型漏水検知センサの設置時期について説明する。
本発明の自己発電型漏水検知センサの設置時期としては、以下の状況が考えられる。 In addition, since water leaks around the waterproof sheet and the water conduit, it is desirable that the self-power generation type water leakage detection device of the present invention be a candidate location for installation. For example, the occurrence of water leakage can be detected by installing the self-power generation type water leakage detection device of the present invention at the lower end of the waterproof sheet.
Next, the installation time of the self-power generation type water leakage detection sensor according to the present invention will be described.
The following situation can be considered as the installation time of the self-power generation type water leakage detection sensor of the present invention.

（１）通常の維持管理業務の一環として、地下施設の施工完了後
（２）近接工事や地上条件の変化など、荷重バランスが変化すると考えられるとき
（３）周辺地山の圧密沈下に伴ってトンネルの変形などの発生が懸念されるとき
（４）地震時などの、変状の急激な進行やトンネル周辺環境の変化が予想されるとき
周辺に漏水箇所が多い区間では、漏水が確認されていないひび割れか目地部でも、今後、漏水が発生する危険性が高い。そのような区間では、通常の維持管理の一環として、本発明の自己発電型漏水検知センサを設置することが考えられる。また、感潮河川直下や海岸付近の漏水は塩分を含むため、地下施設の劣化を急激に進行させる。そのため、ひび割れが急激に進展して、漏水が発生する恐れがあるため、上記した弱点箇所へ事前に本発明の自己発電型漏水検知装置を設置するのが望ましい。 (1) After completion of construction of underground facilities as part of normal maintenance work (2) When load balance is considered to change, such as proximity work or changes in ground conditions (3) With consolidation settlement of surrounding ground When there is concern about the occurrence of deformation of the tunnel (4) When there is a sudden progress of deformation or a change in the environment around the tunnel, such as during an earthquake, water leakage has been confirmed in sections where there are many water leaks in the vicinity. Even if there are no cracks or joints, there is a high risk of water leakage in the future. In such a section, it is conceivable to install the self-power generation type water leakage detection sensor of the present invention as part of normal maintenance. In addition, water leakage directly under the tidal river and near the coast contains salt, which causes the underground facilities to deteriorate rapidly. Therefore, since cracks may develop rapidly and water leakage may occur, it is desirable to install the self-power generation type water leakage detection device of the present invention in advance at the above weak points.

さらに、軟弱な粘土層に位置するトンネルでは、トンネル内部に地下水が流入することで周辺地山の圧密が促進される。それに伴ってトンネルの変形などの発生が懸念される。トンネルの変形が進行すると、既存クラックの進展や、新規クラックの発生で漏水が発生する危険が高まるので、事前に本発明の自己発電型漏水検知センサを設置することが望ましい。   Furthermore, in the tunnel located in the soft clay layer, the groundwater flows into the tunnel and the consolidation of the surrounding ground is promoted. As a result, there are concerns about the occurrence of tunnel deformation. As the deformation of the tunnel progresses, the risk of water leakage due to the development of existing cracks or the occurrence of new cracks increases, so it is desirable to install the self-power generation type water leakage detection sensor of the present invention in advance.

また、地震等による強い作用によっても、覆工変形が進行した場合や、地下水位の変化が予想される場合にも、新たな漏水の発生が懸念されるため、事前に本発明の自己発電型漏水検知装置を設置するのが望ましい。
図２は本発明の第１実施例を示す地下施設の自己発電型漏水検知装置の取り付け状態を示す模式図である。ここでも、地下施設としてトンネルを挙げて説明する。 In addition, since the occurrence of new water leakage is also a concern when lining deformation progresses due to a strong action due to an earthquake or the like, or when a change in groundwater level is expected, the self-power generation type of the present invention in advance. It is desirable to install a leak detector.
FIG. 2 is a schematic diagram showing an attached state of the self-power generation type water leakage detection device for an underground facility according to the first embodiment of the present invention. Again, a tunnel will be described as an underground facility.

この実施例では、予め地下施設としてのトンネル２１内面の目視により、ひび割れ２２が発生している箇所に、図１に示した自己発電型漏水検知センサ２３を取り付けて、漏水が生じた場合には自己発電を行って、漏水の発生を表示装置２５で表示できるように構成している。なお、２４は水を溜める容器である。
図３は本発明の第２実施例を示す地下施設の自己発電型漏水検知装置の取り付け状態を示す模式図である。ここでも、地下施設としてトンネルを挙げて説明する。 In this embodiment, when the self-power generation type water leakage detection sensor 23 shown in FIG. 1 is attached to the location where the crack 22 is generated by visual observation of the inner surface of the tunnel 21 as an underground facility, Self-power generation is performed, and the display device 25 can display the occurrence of water leakage. Reference numeral 24 denotes a container for storing water.
FIG. 3 is a schematic diagram showing an attached state of a self-power generation type water leakage detection device for an underground facility according to a second embodiment of the present invention. Again, a tunnel will be described as an underground facility.

この実施例では、トンネル３１がコンクリートブロック３３などを積み重ねて構成される場合には、トンネル３１のひび割れ３２からの漏水は、表面にできる継目の筋である目地部３４に生じ易いので、この目地部３４に自己発電型漏水検知センサ３５を取り付けて、漏水が生じた場合には自己発電を行って、漏水の発生を表示装置３６で検知できるように構成している。   In this embodiment, when the tunnel 31 is configured by stacking concrete blocks 33 and the like, water leakage from the cracks 32 of the tunnel 31 is likely to occur in the joint portion 34 that is a streak formed on the surface. A self-power generation type water leakage detection sensor 35 is attached to the unit 34 so that when water leakage occurs, self power generation is performed, and the display device 36 can detect the occurrence of water leakage.

図４は本発明の第３実施例を示す地下施設の自己発電型漏水検知装置の取り付け状態を示す模式図である。
この実施例では、トンネル４１のひび割れ４２からの漏水は、トンネル４１の内面に張られた防水シート４３の継ぎ目４４に流れ出す傾向があるので、この継ぎ目４４の防水シート４３下端に自己発電型漏水検知センサ４５を取り付けて、漏水が生じた場合には自己発電を行って、漏水が生じたことを表示装置（図示なし）で表示できるように構成している。 FIG. 4 is a schematic diagram showing an attached state of a self-power generation type water leakage detection device for an underground facility showing a third embodiment of the present invention.
In this embodiment, the water leakage from the crack 42 of the tunnel 41 tends to flow out to the joint 44 of the waterproof sheet 43 stretched on the inner surface of the tunnel 41. A sensor 45 is attached, and when water leakage occurs, self-power generation is performed, and the display device (not shown) can display that water leakage has occurred.

このように、適宜、トンネルからの漏水を自己発電型漏水検知センサで検知して、漏水が生じていることは迅速・的確に自己発電型漏水検知センサ自体に実装される表示装置で表示できるようにする。
更に、かかる表示装置に代えて、無線装置を取り付けて、遠隔の位置に配置された受信装置で受信して表示するようにしてもよい。 In this way, leakage from the tunnel is appropriately detected by the self-power generation type water leakage detection sensor, and the occurrence of water leakage can be quickly and accurately displayed on the display device mounted on the self power generation type water leakage detection sensor itself. To.
Further, instead of such a display device, a wireless device may be attached and received and displayed by a receiving device arranged at a remote position.

なお、本発明は上記実施例に限定されるものではなく、本発明の趣旨に基づき種々の変形が可能であり、これらを本発明の範囲から排除するものではない。   In addition, this invention is not limited to the said Example, Based on the meaning of this invention, a various deformation | transformation is possible and these are not excluded from the scope of the present invention.
