Abstract

PROBLEM TO BE SOLVED: To provide a method capable of detecting a leakage site of a water supply pipeline by olfactory sensation, not by auditory sensation, nor by visual sensation.SOLUTION: A method detects a leakage site of the water supply pipeline embedded in the earth. The method is carried out by focusing an attention to the fact that the materials sensed by olfactory sensation, which is different from the auditory sensation and the visual sensation, are easily diffused from the earth and easily detected, and when the olfactory sensation of a dog is used, the olfactory sensation called to be 100,000 times the human being can be utilized. The method comprises: a step of closing a stop cock to stop the water supply, feeding a pressurized liquid from one of the water faucets after all water faucets are released, and discharging the remaining water in the pipeline; a step of pressurizing smell components contained in the pressurized liquid to be diffused into the earth after discharging the remaining water from the pipeline leakage site; and a step of making a detection animal moving along the pipeline sense the smell component diffused into the earth from the pipeline crack and detect the leakage site.SELECTED DRAWING: Figure 1

Description

この発明は、土中の水道配管での漏水を探知するための漏水検知方法とそれに用いる器具に関する。  The present invention relates to a water leak detection method for detecting a water leak in a water pipe in the soil and an instrument used therefor.

漏水を探知するには、検査員の熟練した技術が不可欠であった。しかし、個々人の感覚に頼ることになるので、判定に統一性がないという不都合がある。そこで、様々な装置が開発されている。例えば、配水管に取り付けたセンサで検出した信号データを記憶し、記憶された信号データから、車両の通行などによる音または振動の一過性の信号データを除去して、これを正常時の信号データと比較することにより漏水の有無を判断し、漏水があれば警報を出すようにした装置が提案されている（特許文献１）。   The skill of the inspector was indispensable to detect leaks. However, there is an inconvenience that the judgment is not uniform because it depends on the sense of the individual. Therefore, various devices have been developed. For example, signal data detected by a sensor attached to a water pipe is stored, and transient signal data of sound or vibration caused by vehicle traffic is removed from the stored signal data, and this is used as a normal signal. An apparatus has been proposed in which the presence or absence of water leakage is determined by comparison with data and an alarm is issued if there is water leakage (Patent Document 1).

しかしながら、この装置では、正常時の信号データと比較して判断するものであるため、判定の結果は、予め記憶しておく正常時の信号データに大きく依存する。また、漏水の程度等様々な要因によって信号データは当然に異なるので、一過性の信号データを除去したとしても、誤診を引き起こす可能性がある。さらに、正常時の信号データを予め記憶させるが、そもそもその正常時の信号データの作成が、地域（例えば交通の激しい場所か、飛行機の航路近くか等）、時期（近くで建築や道路工事などが行われているか、台風が来たか、強風の吹く季節か等）などにより差異があるため、一定せず、漏水検出がとても難しいとしている。   However, in this device, since the determination is made by comparing with the signal data at the normal time, the determination result largely depends on the signal data at the normal time stored in advance. In addition, since the signal data naturally varies depending on various factors such as the degree of water leakage, even if the temporary signal data is removed, there is a possibility of causing a misdiagnosis. In addition, normal signal data is stored in advance, but in the first place the normal signal data is created according to the region (for example, where traffic is heavy or near the route of the airplane), time (such as construction or road construction nearby) It is not constant, and it is difficult to detect water leaks.

そこで、安価にして誰でも操作でき親しみやすいうえに、誤診もなくすことができるようにするため、センサで検出した音波または振動波の信号データを、そのスペクトルを示すべく変換して表示装置に表示する検出信号表示ステップと、上記検出した信号データを、フィルタリング指令を待って、予め作成し記憶した雑音除去フィルタ、または予め記憶した雑音サンプル信号を基に作成した雑音除去フィルタでフィルタリングするフィルタリングステップと、該フィルタリングステップで絞り込んだ絞込み信号のスペクトルを表示する絞込み信号表示ステップを有する漏水探知方法が提案されている（特許文献２）。   Therefore, in order to be inexpensive and easy for anyone to operate and be familiar with, and to eliminate misdiagnosis, the signal data of the sound wave or vibration wave detected by the sensor is converted to display its spectrum and displayed on the display device A detection signal display step, and a filtering step of filtering the detected signal data with a noise removal filter created and stored in advance, or a noise removal filter created based on a noise sample signal stored in advance, after waiting for a filtering command; A water leak detection method having a narrowed signal display step for displaying a spectrum of a narrowed signal narrowed down in the filtering step has been proposed (Patent Document 2).

しかしながら、センサで漏水現象による音波または振動波の信号データを検知する方法は如何にしても測定環境の外乱の影響を受けやすく、機械性能を高感度にすると、設備費が高く、検知制度に限界がある。そこで、発光物質を含有する漏水検査液を用いる方法も提案されている（特許文献３）が、建物の場合はいざ知らず、地中深く配管された水道管からの漏水を視覚的に検知することは困難である。そこで、聴覚でなく、視覚でもなく、漏水箇所を検知できる方法を提供することを課題とする。
However, the method of detecting sound wave or vibration wave signal data due to water leakage with a sensor is in any way susceptible to disturbances in the measurement environment, and if the machine performance is highly sensitive, the equipment cost is high and the detection system is limited. There is. Then, although the method using the water leak test liquid containing a luminescent substance is also proposed (patent document 3), in the case of a building, it does not know, but to detect the water leak from the water pipe piped deep underground. It is difficult. Then, let it be a subject to provide the method which can detect a water leak location not a hearing but a vision.

本発明者は、従来の、センサでの漏水現象による音波または振動波の信号データを検知する聴覚による方法は、機械的精度の限界がある一方、発光物質を含有する漏水検査液を用いる視覚によるものは、地中での漏水現象に伴う検知には限界が見られることに鑑み、鋭意研究の結果、完成したもので、臭覚によるものは、聴覚、視覚と違って、土中から拡散しやすく、検知しやすいだけでなく、犬の臭覚を利用すると、人間の１０万倍といわれる臭覚を活用することができることに着目したもので、土中に埋め込まれた水道配管の漏水箇所を検出する方法であって、止水栓を閉鎖して給水を停め、全ての蛇口を開放した後その一つの蛇口から加圧流体を送り込み、配管中の残水を排出する工程と、残水排出後,加圧流体に含まれる臭い成分を加圧して配管漏水箇所から土中に拡散させる工程と、配管亀裂から土中に拡散する臭い成分を配管に沿って移動する検知動物に感知させ、漏水箇所を検出させる工程からなることを特徴とする水道水漏水箇所検査方法にあり、好ましくは、加圧流体として加圧気体を用い、止水栓を閉鎖して給水を停め、全ての蛇口を開放した後その一つの蛇口にコンプレッサを接続して加圧気体を送り込み、配管中の残水を排出する工程と、残水排出後,コンプレッサーから加圧気体に臭い成分を含めて配管中に供給して充たす工程と、配管中に充たした臭い成分を含む気体を加圧して配管漏水箇所から土中に拡散させる工程と、配管から土中に拡散する臭い成分を配管に沿って移動する検知動物に感知させ、漏水箇所を検出させる工程からなることを特徴とする。本発明においては、探索動物としては麻薬等を探索する警察犬等の犬種が好ましいが、豚等のその他の臭気検知動物であってもよい。   The inventor of the present invention uses a visual method using a leak test liquid containing a luminescent substance, while a conventional auditory method for detecting sound wave or vibration wave signal data due to a water leak phenomenon in a sensor has a limit in mechanical accuracy. Things were completed as a result of intensive research in view of the limitations of detection due to water leakage phenomenon in the ground, and those due to olfaction easily diffuse from the soil, unlike hearing and vision. In addition to being easy to detect, using the sense of smell of dogs, it is possible to utilize the sense of smell that is said to be 100,000 times that of humans, and a method for detecting leaks in water pipes embedded in the soil Then, shut off the stop cock, stop the water supply, open all the faucets, send pressurized fluid from one of the faucets, drain the residual water in the pipe, Adds odorous components contained in pressurized fluid The method comprises a step of compressing and diffusing into the soil from a pipe leakage point, and a step of causing a detection animal that moves along the piping to detect a odor component that diffuses into the soil from a pipe crack and detecting the leakage point. There is a method for inspecting tap water leaks, preferably using pressurized gas as the pressurized fluid, closing the stop cock and stopping the water supply, opening all the faucets and connecting a compressor to that one faucet. A process of sending pressurized gas and discharging residual water in the pipe, a process of supplying and filling the pressurized gas including odor components from the compressor into the pipe after discharging the residual water, and an odor ingredient filled in the pipe A process of pressurizing a gas containing water and diffusing it from the leaked part of the pipe into the soil, and a process of detecting the leaked part by making the detection animal that moves along the pipe sense the odorous component that diffuses from the pipe into the soil Features The In the present invention, the search animal is preferably a dog breed such as a police dog searching for drugs or the like, but may be other odor detection animals such as pigs.

本発明によれば、外乱の影響を受けやすい聴覚、地表面からの地中内の発光が観測しにくい視覚に比して臭いは地表面からの観測が容易である上、犬の臭覚を利用するので、訓練された犬の臭覚を利用して確実に漏水箇所を地表で探索することができる。   According to the present invention, the odor can be easily observed from the ground surface as compared to the hearing that is easily affected by disturbance, and the sight in which light emission in the ground from the ground surface is difficult to observe. As a result, it is possible to reliably search for a water leak point on the ground surface using the sense of smell of the trained dog.

土中に埋め込まれた水道管の漏水箇所を検出する方法に使用する臭い成分を含む流体としては、気体を利用するのが好ましく、圧縮空気を供給するコンプレッサと、臭い成分を圧縮空気に混入させるパヒュームメーカーと、コンプレッサとパヒュームメーカーとを接続するエアホースと、パヒュームメーカーと水栓柱とを接続するエアーホースとからなり、パヒュームメーカーが円筒体からなり、下半分にノーズワークウォータを収納する貯蔵部とコンプレッサーからの圧縮空気をノーズワークウォータの貯蔵部中でバブリングさせる多数の気泡孔を有する気泡筒を備え、コンプレッサからの圧縮空気をノーズワークウォータ中に送り込み、臭い成分を含む気体を生成する装置を用いるのがよい。なお、本発明において、ノーズワークウォータとは水道管内に送る香り又はにおいは人畜無害で水と導水を流すと水道管内に付着した香りが残ることなく水道水とともに排出できる水をいい、また、コンクリートなどを透過する貫通力をもった香りを生成できる水が望ましく、植物由来のアロマオイルなどを薄めた液体などを使用して漏水探知犬の探索を容易にする水溶液をいう。さらに、パヒュームメーカーとはコンプレッサより送られるエアーをノーズワークウォータ（液体）中で小さな気泡状にして噴射することにより臭気を帯びたエアーを製造する装置をいう。   As a fluid containing an odorous component used in a method for detecting a leaking point of a water pipe embedded in the soil, it is preferable to use a gas, and a compressor for supplying compressed air and an odorous component to be mixed into the compressed air A storage unit that consists of a perfume maker, an air hose connecting the compressor and the perfume maker, and an air hose connecting the perfume maker and the faucet column. The perfume maker consists of a cylindrical body and stores the nose work water in the lower half. And a bubble cylinder having a large number of bubble holes for bubbling compressed air from the compressor in the reservoir of the nose work water, and sending compressed air from the compressor into the nose work water to generate a gas containing an odor component Should be used. In the present invention, nose work water refers to water that can be discharged together with tap water without leaving a scent attached to the water pipe when the scent or odor sent into the water pipe is harmless to humans and water and water are passed through the water pipe. Water that can generate a scent with a penetrating ability is desirable, and it refers to an aqueous solution that makes it easy to search for a leak detection dog using a liquid obtained by diluting a plant-derived aroma oil or the like. Furthermore, a perfume maker is an apparatus that produces odorous air by injecting air sent from a compressor in a nose work water (liquid) in the form of small bubbles.

漏水箇所が探索されると、路中に埋め込まれた水道管の漏水箇所を配管に沿って掘削するが、配管を表出させるには、５０から９０度の角度で屈曲する「く」の字状屈曲部の両側面で閉鎖し、先端部から掘削爪を突出させてなり、両側面を親指と小指で支持し、屈曲部中央から前方に人差し指、中指及び薬指を伸ばし、屈曲部頂部を支点とし、手首揺動させて掘削し、掘削土をバケット内に収納して掘り出し可能である手動バケットを用いるのが好ましい。   When the leak location is searched, the leak location of the water pipe embedded in the road is excavated along the pipe, but in order to expose the pipe, it is bent at an angle of 50 to 90 degrees. It is closed on both sides of the bent part, and the excavation claw is protruded from the tip part, both sides are supported by the thumb and little finger, the index finger, middle finger and ring finger are extended forward from the center of the bent part, and the top of the bent part is supported. It is preferable to use a manual bucket that can be excavated by swinging the wrist and storing the excavated soil in the bucket.

以下、本発明の好ましい実施態様を添付図面にしたがって説明する。
本発明の漏水検査方法は図1に示すように、次のステップで行われる。
（第1ステップ）排水工程：
止水栓１を閉鎖して給水を停める。ついで、全ての蛇口を開放した後その一つの蛇口（作業のしやすい水栓柱：通常コン柱という）にカプラ２を取り付け、コンプレッサ３をエアホース４を介して接続して加圧空気を送り込み、配管中の残水を排出する。
（第２ステップ）充填工程：
残水排出後,コンプレッサー３から加圧空気に臭い成分を含めて配管中供給して満たす。臭い成分を含む気体を作成するために図2に示すパヒュームメーカー１０を用いる。この土中に埋め込まれた水道管の漏水箇所を検出する方法に使用する臭い成分気体を生成するシステムは、圧縮空気を供給するコンプレッサー３と、臭い成分を圧縮空気に混入させるパヒュームメーカー１０と、コンプレッサー３とパヒュームメーカー１０とを接続する第1エアホース４と、パヒュームメーカーと水栓柱とを接続する第2エアーホース５とからなる。パヒュームメーカー１０は密封円筒体１１からなり、下半分にノーズワークウォータＷを収納する貯蔵部１２を備え、該貯蔵部１２のノーズウオータ中に多数の気泡孔12ａを有する気泡筒１２を配管し、コンプレッサー３からの圧縮空気を第1エアパイプ４で送気口１１ａから気泡筒１２に送り込んで、ノーズワークウォータＷ中でバブリングさせ、臭い成分を含む気体を生成させ、排出口１１ｂから排出し、第2エアバブル５で止水栓１に送るようになっている。１１ｃは注液口である。ここで、ノーズワークウォータＷは人畜無害で水道水を流すと水道管内に香りが残りにくいのが好ましく、また、コンクリートなどを貫通する透過力をもった植物由来のアロマオイル等を水に含有させて用いるのが好ましい。
（第3ステップ）拡散工程：
配管に満たした臭い成分の気体を加圧して配管漏水箇所から土中に拡散させる。加圧は０．３ＭＰｓ程度の圧力で配管亀裂から土中に臭い成分を拡散させることができる。加圧力は臭い成分を含む空気の土中拡散性能を勘案して適宜決定することができる。
（第4ステップ）探索工程：
配管から土中に拡散する臭い成分を配管に沿って検査員Ｍが検知犬Ｄを移動させると、漏水箇所から土中に拡散する臭い成分を検知犬Ｄが検出する。この検出犬Ｄは臭覚ハウンドと呼ばれる犬種に特定の臭い成分を覚えさせる訓練を施す。それによって、同種の臭い成分をノーズワークウォータＷ中に含ませておけば、そこでバブリングした空気を検出用空気として使用すれば、配管亀裂箇所から土中に臭い成分が拡散し、漏水箇所を検出することができる。
（第5ステップ）掘削工程：
土中に埋め込まれた水道管の漏水箇所を配管に沿って掘削するには図4に示す手動バケット２０を用いるのがよい。５０から９０度の角度で屈曲する「く」の字状屈曲片２１の両側面２２で閉鎖し、先端部から掘削爪２３を突出させてなる。このバケット２０は図5に示すように、両側面２２を親指と小指で支持し、屈曲片２１の中央２１ａから前方に人差し指、中指及び薬指を伸ばし、屈曲片頂部を支点とし、手首揺動させて掘削し、掘削土をバケット内に収納してバケット幅で所定地面の掘り出しが可能である。 Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 1, the water leakage inspection method of the present invention is performed in the following steps.
(First step) Drainage process:
Close the stop cock 1 and stop water supply. Next, after opening all the faucets, the coupler 2 is attached to one of the faucets (the faucet column that is easy to work: usually called the con column), and the compressor 3 is connected via the air hose 4 to send pressurized air, Drain the remaining water in the piping.
(Second step) Filling process:
After the residual water is discharged, the compressed air is supplied from the compressor 3 to the pressurized air including the odor components and filled. A perfume maker 10 shown in FIG. 2 is used to create a gas containing an odor component. A system for generating an odor component gas used in a method for detecting a water leak point of a water pipe embedded in the soil includes a compressor 3 that supplies compressed air, a perfume maker 10 that mixes the odor component into the compressed air, It consists of a first air hose 4 that connects the compressor 3 and the perfume maker 10, and a second air hose 5 that connects the perfume maker and the faucet column. The perfume maker 10 is composed of a sealed cylindrical body 11, and includes a storage portion 12 that stores the nose work water W in the lower half, and pipes a bubble cylinder 12 having a number of bubble holes 12 a in the nose water of the storage portion 12, Compressed air from the compressor 3 is sent from the air inlet 11a to the bubble cylinder 12 through the first air pipe 4 and bubbled in the nose work water W to generate gas containing odorous components, discharged from the outlet 11b, 2 Air bubbles 5 are sent to the stop cock 1. 11c is a liquid injection port. Here, the nose work water W is preferably harmless to humans, and it is preferable that no scent remains in the water pipe when flowing tap water. In addition, plant-derived aroma oil or the like having permeability that penetrates concrete or the like is contained in the water. Are preferably used.
(3rd step) Diffusion process:
Pressurize the gas of the odor component filled in the pipe and diffuse it from the pipe leakage point into the soil. The pressurization can diffuse the odor component from the pipe crack into the soil at a pressure of about 0.3 MPs. The applied pressure can be appropriately determined in consideration of the soil diffusion performance of air containing odorous components.
(4th step) Search process:
When the inspector M moves the detection dog D along the pipe with the odor component that diffuses from the pipe into the soil, the detection dog D detects the odor component that diffuses into the soil from the leaked location. This detection dog D is trained to remember a specific odor component in a dog type called a odor hound. As a result, if the same kind of odorous component is included in the nose work water W, if the air bubbled there is used as detection air, the odorous component diffuses into the soil from the pipe crack location, and the leak location is detected. can do.
(5th step) Drilling process:
A manual bucket 20 shown in FIG. 4 is preferably used for excavating a water leak point of a water pipe embedded in the soil along the pipe. The claw-shaped bent piece 21 is bent at an angle of 50 to 90 degrees and is closed at both side surfaces 22 so that the excavation claw 23 protrudes from the tip. As shown in FIG. 5, the bucket 20 supports both side surfaces 22 with thumbs and little fingers, extends the index finger, middle finger and ring finger forward from the center 21a of the bent piece 21, and swings the wrist with the bent piece top as a fulcrum. The excavated soil can be stored in a bucket and the predetermined ground can be excavated with the bucket width.
