Description
本発明は、埋設配管の埋込位置を示す杭構造体に関し、より詳細には、震災時の給水設備および消火設備等の復旧のために好適に用いられる杭構造体を含む埋込配管構造、該杭構造体および該杭構造体の地盤への施工方法に関する。 The present invention relates to a pile structure showing an embedding position of an embedded pipe, and more specifically, an embedded pipe structure including a pile structure that is preferably used for restoration of water supply equipment and fire extinguishing equipment at the time of an earthquake disaster. The present invention relates to a method for constructing the pile structure and the ground of the pile structure.
大規模地震などの災害時において、一定の給水を確保することが水道事業者の責務として求められる。特に病院、介護施設などの災害弱者施設、避難所となる施設においては、飲料水だけでなく消火用水、医療用水、生活用水などを確保できる体制が求められる。 In the event of a disaster such as a large-scale earthquake, it is the responsibility of the water utility to ensure a certain level of water supply. In particular, facilities that are vulnerable to disasters such as hospitals and nursing homes and facilities that serve as shelters are required to have a system that can secure not only drinking water but also fire-fighting water, medical water, and domestic water.
病院等を含め現在の建物の大部分では、水道局から供給される水道水を受水槽や高置水槽を通じて給水する、いわゆる貯水槽水道が設けられている。この貯水槽水道では、震災時に水道の給水が停止したとしても、貯水量および使用量に応じて数時間から数日間の給水を確保することができ、給水車により直接受水槽給水などを行うことでさらに長期の給水を確保することができる。また、貯水槽水道を通じて給水が可能であることから、建物内の蛇口を使用することが可能である。このような観点から、上記施設における災害時の応急給水としても貯水槽水道を有効に活用することが期待されている。 In most of the current buildings including hospitals, so-called water storage tanks are provided that supply tap water supplied from the Waterworks Bureau through water receiving tanks or elevated water tanks. In this water tank water supply, even if water supply stops during the earthquake, water supply for several hours to several days can be secured depending on the amount of water stored and used, and water supply tank water supply etc. directly by water tank In this way, long-term water supply can be secured. In addition, since water can be supplied through the water tank, faucets in the building can be used. From such a viewpoint, it is expected to effectively use the water tank water as an emergency water supply at the time of disaster in the above facilities.
しかしながら、貯水槽水道の貯水槽や配管に漏水があると、水量確保の面で困難となり、貯水槽の保有水が短期間で枯渇したり、給水車で応急給水を行った場合でも給水量が間に合わず断水したりする可能性もある。病院では、常時１日当たり所定量の医療用水を必要とするため、水道局や自衛隊の給水車からの応急給水があっても不足しがちとなるが、漏水を放置してしまうと病院機能の喪失にも繋がりかねない。下記表１は、病院の応急給水対応例を示す。 However, if there is water leakage in the water tank or piping of the water tank water supply, it will be difficult to secure the amount of water, and even if the water held in the water tank is depleted in a short period of time or emergency water supply is performed with a water supply vehicle, There is also a possibility that the water will stop in time. Because hospitals always require a certain amount of medical water per day, even if there is an emergency water supply from a water supply vehicle of the Waterworks Bureau or the Self-Defense Forces, it tends to be insufficient. Can also lead to. Table 1 below shows examples of emergency water supply in hospitals.
表１を参照すると、漏水が発生してしまうと、災害発生後短時間のうちに断水に陥り、応急給水の実施にもかかわらず断水が生じ得ることが判る。また、対応例１において１時間当たり少なくとも９トンの応急給水が必要とされたという事実は、それに相当する水量が漏水により失われていることを示している。したがって、給水タンクや貯水槽など配管の漏水箇所の特定を含めた給水設備の復旧が急務であり、災害発生後できる限り早急に対応しなければならない。一方、病院等では、患者対応が優先されるため、漏水確認等が後手になりがちとなる。また、震災が夜間に発生してしまうと、さらに復旧が困難となる。 Referring to Table 1, it can be seen that if water leakage occurs, water will fall in a short time after the disaster occurs, and water breakage may occur despite the emergency water supply. In addition, the fact that at least 9 tons of emergency water is required per hour in the correspondence example 1 indicates that the corresponding amount of water is lost due to water leakage. Therefore, there is an urgent need to restore water supply facilities, including the identification of leak points in pipes such as water tanks and storage tanks, and it is necessary to respond as soon as possible after a disaster occurs. On the other hand, in hospitals and the like, priority is given to patient handling, so water leakage confirmation and the like tends to be behind. In addition, if the earthquake occurs at night, recovery will become more difficult.
過去の実例を建物内、設備、埋設配管に分類して復旧状況を調査してみると、貯水槽本体配管や建物内での漏水であれば比較的容易に漏水箇所が特定されているものの、地中に埋め込まれている埋設管の漏水位置の特定には多くの時間を要することが判明した。漏水箇所の特定は、震災直後に漏水が確認できない場合には、給水再開後に漏水検査をして行うこととなるが、給水再開後に漏水が判明すると、さらに給水設備の復旧が遅れてしまう。このため給水が停止している間に貯水槽水道の給水設備を復旧することが重要となる。 The past examples are classified into buildings, equipment, and buried piping, and the recovery situation is investigated.If water leakage occurs in the water tank main body piping or building, the leakage location is relatively easily identified. It has been found that it takes a lot of time to identify the location of water leakage in buried pipes buried in the ground. If water leakage cannot be confirmed immediately after the earthquake, the location of the water leakage will be checked by conducting a water leakage inspection after resuming water supply. However, if water leakage is identified after resumption of water supply, the restoration of water supply facilities will be delayed. For this reason, it is important to restore the water supply system of the water tank water supply while the water supply is stopped.
このような背景から埋設配管の位置を迅速に把握し、その漏水箇所を震災後可能な限り早急に発見することを可能とする技術の開発が望まれていた。従来では、埋設配管の埋込位置を標示する埋設標示杭が打ち込まれ、これにより埋設配管の位置をある程度把握することができる（例えば特許文献１）。しかしながら、これら埋設標示杭は、刻印等の標示にすぎず、摩耗等により確認が困難である場合もあり、夜間の発見はさらに困難となる。上述したように、漏水対応は迅速に対応しなければならず、夜明けを待ってから漏水箇所の特定を開始するのでは充分ではない。 From such a background, it has been desired to develop a technique capable of quickly grasping the position of the buried piping and finding the leakage point as soon as possible after the earthquake. Conventionally, a buried marking pile for marking the buried position of the buried pipe is driven, and thereby the position of the buried pipe can be grasped to some extent (for example, Patent Document 1). However, these buried marking stakes are only markings such as stamps, and it may be difficult to confirm due to wear or the like, making it even more difficult to find at night. As described above, it is necessary to respond quickly to water leakage, and it is not sufficient to wait until dawn and start specifying the location of water leakage.
また、仮に杭の位置を発見することができたとしても、標示杭は単に埋込位置を標示するものにすぎないため、漏水箇所を特定することは困難である。漏水の発生を比較的発見し易い地上漏水であっても、必ずしも漏水箇所の近辺に生じるものではないため、埋込配管の漏水箇所の特定は依然として困難であり、砂地地盤等では、地上漏水が起こりにくいため漏水箇所の特定が極めて困難となる。平時では音聴棒や漏水探知器を用いた音聴調査、相関調査などの漏水検査技術も適用可能であるが、作業者の熟練、専用装置の配備、充分な作業時間を必要とし、災害時の対策としては妥当ではない。 Even if the position of the pile can be found, it is difficult to specify the location of the water leak because the marking pile is merely a mark indicating the embedding position. Even if ground leakage is relatively easy to detect the occurrence of water leakage, it does not necessarily occur in the vicinity of the water leakage location, so it is still difficult to identify the water leakage location of the embedded piping. Since it is difficult to occur, it is extremely difficult to identify the location of the water leak. In normal times, leakage inspection technologies such as sound survey using a sound stick or leak detector and correlation survey can also be applied. However, it requires skilled workers, the installation of dedicated equipment, and sufficient work time. It is not appropriate as a countermeasure.
したがって、埋設配管の埋込位置を夜間においても容易に識別可能とし、かつ、埋込配管の漏水箇所を迅速かつ容易に特定可能な、低コスト、かつメンテナンス容易性が高い技術の開発が求められていた。 Therefore, there is a need for the development of a low-cost, high-maintenance technology that makes it possible to easily identify the embedding position of the buried piping even at night, and to quickly and easily identify the leak location of the buried piping. It was.
本発明は、上記従来技術の課題に鑑みてなされたものであり、本発明は、埋設配管の埋込位置および漏水箇所を容易かつ迅速に特定可能とし、かつ夜間に発生した震災にも対応可能な杭構造体を含む埋込配管構造、該杭構造体および該杭構造体の地盤への施工方法を提供することを目的とする。 The present invention has been made in view of the above-described problems of the prior art, and the present invention makes it possible to easily and quickly identify the embedding position and water leakage location of the buried piping and cope with an earthquake disaster occurring at night. An object is to provide an embedded piping structure including a possible pile structure, a method for constructing the pile structure, and a ground of the pile structure.

The pile structure in the embedded piping structure of the present invention is disposed in the vicinity of the embedded piping such as a water supply pipe, and is provided with an intake port for taking in a fluid such as water, and the fluid provided in the head of the pile structure. And a discharge port that discharges outside the structure. Furthermore, the pile structure of the present invention includes a seismic mechanism that senses vibration of a set strength or higher, and a light emitting means that emits light in response to the vibration sense mechanism sensing vibration. An internal flow path inside the pile structure is formed between the intake port and the discharge port. Furthermore, the embedded piping structure of the present invention further includes an external channel forming means for forming an external channel that surrounds the embedded piping and guides the fluid leaked from the embedded piping to the intake of the pile structure. Including.
また本発明の杭構造体は、取入口と、上記内部流路を構成し取入口から流入する流体を導く脚部流路とが設けられる脚部を含んで構成することができる。また杭構造体は、上記内部流路を構成し、脚部流路と連通する頭部流路と、頭部流路を流れる流体を放出する放出口と、上記感震機構と、上記発光手段とが設けられる頭部を含んで構成することができる。さらに本発明では、上記発光手段は、化学発光材料または電気発光素子を用いることができる。化学発光材料を用いる場合には、杭構造体は、感震機構が地震を感知して作動したことに応答して化学発光材料の溶液の混合を引き起こすよう構成される。電気発光素子を用いる場合には、杭構造体は、感震機構が地震を感知して作動したことに応答して電気発光素子へ電力を供給するための電気接点を接続するよう構成される。また本発明では、杭構造体は、埋込配管の継手部分または曲り部分に好適に設けることができ、建物引込付近給水管、あるいは建物外給水栓の池、散水栓、洗い場近傍の埋込配管に対応して好適に設けることができる。また本発明では、上記脚部は、入れ子状に組合わされて伸縮可能な複数の単位筒体で構成することができる。上記流路形成手段は、埋込配管を囲繞して、杭構造体の頭部までの流体の流路を確保するシート状部材を用いることができる。 Moreover, the pile structure of this invention can be comprised including the leg part in which an intake port and the leg flow path which comprises the said internal flow path and guides the fluid which flows in from an intake port are provided. The pile structure constitutes the internal flow path, the head flow path communicating with the leg flow path, the discharge port for discharging the fluid flowing through the head flow path, the seismic mechanism, and the light emitting means. The head can be configured to be provided. Further, in the present invention, the light emitting means can use a chemiluminescent material or an electroluminescent element. When using a chemiluminescent material, the pile structure is configured to cause mixing of the chemiluminescent material solution in response to the seismic mechanism acting upon sensing the earthquake. In the case of using an electroluminescent element, the pile structure is configured to connect an electrical contact for supplying power to the electroluminescent element in response to the seismic mechanism operating upon sensing an earthquake. Further, in the present invention, the pile structure can be suitably provided in the joint portion or the bent portion of the embedded pipe, and the water supply pipe near the building draw-in, or the water supply pond outside the building, the water spigot, the embedded pipe near the washing place It can provide suitably corresponding to. Further, in the present invention, the leg portion can be composed of a plurality of unit cylinders that are telescopically combined. The flow path forming means can use a sheet-like member that surrounds the embedded pipe and secures a flow path of fluid to the head of the pile structure.
さらに本発明によれば、地中に埋め込まれた埋込配管を標示する上記杭構造体を設置する施工方法が提供される。本発明の工方法は、設置対象の埋込配管の箇所を露わにする工程と、流路形成手段で埋込配管を囲繞し、埋込配管から漏出した流体を杭構造体の取入口まで導くための外部流路を形成する工程と、埋込配管および外部流路の少なくとも一部を埋め戻す工程と、外部流路と内部流路とが連通するように杭構造体を打ち込んで、外部流路を閉じる工程とを含む。 Furthermore, according to this invention, the construction method which installs the said pile structure which marks the embedding piping embedded in the ground is provided. The method of the present invention includes a step of exposing the location of the embedded pipe to be installed, surrounds the embedded pipe with the flow path forming means, and allows the fluid leaking from the embedded pipe to the intake of the pile structure The step of forming an external flow path for guiding, the step of refilling at least part of the embedded pipe and the external flow path, and driving the pile structure so that the external flow path and the internal flow path communicate with each other, Closing the flow path.
上記構成によれば、埋込配管から漏れ出した水などの流体を埋込配管の近くに設けた取入口から取り入れて、頭部の放出口から放出し、かつ所定強度の地震に感応して発光する杭構造体を備えるため、本杭構造体を用いることで、埋設配管の埋込位置を夜間においても容易かつ早期に識別することが可能となり、かつ当該杭構造体の検知範囲において漏水が発生しているか否かを容易に判断することが可能となる。また、これらの判断には、作業者の熟練等を必要せず、漏水箇所の特定が困難な砂地地盤等であっても、好適に漏水の発生を検知することが可能となる。したがって、震災直後からの貯水槽水道の早期復旧に貢献することができ、これにより、震災時の医療用水や生活用水の確保が容易なものとなる。 According to the above configuration, fluid such as water leaking from the buried pipe is taken in from the intake provided near the buried pipe, discharged from the head outlet, and sensitive to earthquakes of a predetermined intensity. Since the pile structure that emits light is used, it is possible to easily and quickly identify the embedding position of the buried piping even at night by using this pile structure, and water leakage is detected in the detection range of the pile structure. It is possible to easily determine whether or not it has occurred. Moreover, it is possible to detect the occurrence of water leakage suitably even in sandy ground or the like where it is difficult to specify the location of the water leakage for these determinations without requiring the skill of the operator. Therefore, it is possible to contribute to the early restoration of the water tank water supply immediately after the earthquake disaster, thereby making it easy to secure medical water and domestic water at the time of the earthquake disaster.
以下、本発明を具体的な実施形態をもって説明するが、本発明は、後述する実施形態に限定されるものではない。 Hereinafter, although this invention is demonstrated with specific embodiment, this invention is not limited to embodiment mentioned later.
図１は、貯水槽水道が設けられた施設の概略を示す図である。図１に示す施設１００には、受水槽１１２が設けられた第１の建物１１０と、屋上に高置水槽１２２が設けられた第２の建物１２０と、屋上の高置水槽１２２から落差水圧で水道水の供給を受ける冷却塔１４２および消火用補給水槽１４４が設けられた第３の建物１４０とが含まれる。受水槽１１２は、配水管１０２から水道メータ１０４を経由して引き込まれる水道水を貯水する。受水槽１１２に貯留された水道水は、電動ポンプ１１４によって、建物１２０の屋上に揚水されて、屋上に設けられた高置水槽１２２に貯水される。これ以降は、高置水槽１２２の高低差による水圧により、建物１２０および建物１４０内の給水栓や建物外給水栓に供給される。建物外給水栓には、図示しない池や散水栓１３０、洗い場１３１などが含まれる。設備関係としては、消火水槽１２３と、上述した冷却塔１４２および消火用補給水槽１４４が図示されている。なお、水道メータ１０４以降の給水配管は、一般に施設１００の管理者に維持管理の義務が課せられている。 FIG. 1 is a diagram showing an outline of a facility provided with a water tank. The facility 100 shown in FIG. 1 includes a first building 110 provided with a water receiving tank 112, a second building 120 provided with a high water tank 122 on the roof, and a drop water pressure from the high water tank 122 on the roof. A cooling tower 142 for receiving tap water and a third building 140 provided with a fire-supplementing replenishing water tank 144 are included. The water receiving tank 112 stores tap water drawn from the distribution pipe 102 via the water meter 104. The tap water stored in the water receiving tank 112 is pumped to the roof of the building 120 by the electric pump 114 and stored in the elevated water tank 122 provided on the roof. Thereafter, the water is supplied to the water faucet in the building 120 and the building 140 and the water faucet outside the building by the water pressure due to the height difference of the elevated water tank 122. The external water faucet includes a pond, a water faucet 130, a washing place 131, and the like (not shown). As the equipment relation, the fire extinguishing water tank 123, the cooling tower 142 and the fire-supplementing replenishing water tank 144 described above are illustrated. In addition, the water supply piping after the water meter 104 is generally obliged to maintain and manage the facility 100 manager.
図１に示す施設１００には、震災時に漏水箇所の特定を容易化するべく本発明の杭構造体２２０が設けられている。本発明の杭構造体２２０は、詳細については後述するが、地中に埋め込まれた給水配管の上方に当たる位置の地上に頭部を露出させるように設けられ、地震に応答して発光するとともに、当該給水配管の漏水の認識を容易とするべく給水配管から漏れ出た水を放出するよう構成されている。図１に示す施設１００では、配水管１０２、水道メータ１０４から受水槽１１２を接続する給水配管１０６の埋込区間Ａ、受水槽１１２の電動ポンプ１１４から高置水槽１２２とを接続する給水配管１１６の埋込区間Ｂと、高置水槽１２２から接続する給水配管１２４の埋込区間Ｃとにおける漏水が、本発明の杭構造体による好適な検知対象となる。また、災害時の消火用水の確保のため、消火配管１２６の埋込区間における漏水を検知対象としてもよい。 The facility 100 shown in FIG. 1 is provided with a pile structure 220 of the present invention in order to facilitate the identification of a water leakage location during an earthquake disaster. The pile structure 220 of the present invention, which will be described in detail later, is provided so as to expose the head on the ground at a position corresponding to the upper side of the water supply pipe embedded in the ground, and emits light in response to an earthquake, In order to make it easy to recognize the leakage of the water supply pipe, the water leaked from the water supply pipe is discharged. In the facility 100 shown in FIG. 1, a water supply pipe 116, an embedding section A of a water supply pipe 106 connecting a water receiving tank 112 from a water meter 104, and a water supply pipe 116 connecting an elevated water tank 122 from an electric pump 114 of the water receiving tank 112. Water leakage in the embedded section B and the embedded section C of the water supply pipe 124 connected from the elevated water tank 122 is a suitable detection target by the pile structure of the present invention. In addition, in order to secure water for fire extinguishing in the event of a disaster, water leakage in an embedded section of the fire extinguishing pipe 126 may be detected.
なお、これまでの震災後の漏水状況の調査結果から、特に建物引込付近給水管、建物外給水栓の洗い場１３１の付近で漏水が起こりやすいことが知られているため、このような埋め込まれた給水配管（以下、地中に埋め込まれた給水配管の箇所を埋込給水配管ということもある。）の箇所に本発明の杭構造体２２０を設けることが好ましい。 In addition, it is known from the survey results of water leakage status after the earthquake so far that water leakage is likely to occur especially near the water supply pipe near the building entrance and the wash basin 131 of the faucet outside the building. It is preferable to provide the pile structure 220 of the present invention at the location of the water supply piping (hereinafter, the location of the water supply piping embedded in the ground may be referred to as the embedded water supply piping).
なお、図１は、本発明の杭構造体２２０の好適な設置位置を例示することを目的とするものであり、本発明の杭構造体２２０が設けられる箇所は、図１に示すものに限定されるものではなく、本発明の杭構造体２２０は、如何なる施設の埋め込まれた配管に適用することができる。例えば、水道メータ１０４以降、直接１次給水圧で建物共通として洗い場塔の建物外給水栓に給水配管を設けている場合もあり、このような給水配管の埋込区間も本発明の杭構造体による好適な検知対象となる。 In addition, FIG. 1 aims at illustrating the suitable installation position of the pile structure 220 of this invention, and the location where the pile structure 220 of this invention is provided is limited to what is shown in FIG. Instead, the pile structure 220 of the present invention can be applied to the embedded piping of any facility. For example, after the water meter 104, a water supply pipe may be provided directly outside the building faucet of the washroom tower as a common building directly at the primary water supply pressure. Such a buried section of the water supply pipe is also a pile structure of the present invention. It becomes the suitable detection object by.
また、施設には、中継水槽が設置される場合がある。中継水槽は、建物が高台のため水圧不足が想定される場合に設置され、受水槽から給水を受けて中継水槽（高台）に貯水する。通常、中継水槽は、図１に示す建物１１０および建物１２０の間に設けられるが、この場合、受水槽１１２から中継水槽までの給水配管の埋込区画と、中継水槽から建物１２０上の高置水槽１２２までの給水配管の埋込区画とが新たな検知対象となる。また、建物１２０と建物１４０が同じ規模の施設では、建物１２０と建物１４０との両方に高置水槽が設けられることとなる。この場合、受水槽１１２の電動ポンプ１１４から建物１２０および建物１４０上の２つの高置水槽までの２つの給水配管の埋込区画とが検知対象となる。 In addition, there may be a relay tank installed in the facility. The relay water tank is installed when water pressure shortage is assumed due to the high ground of the building, receives water from the water receiving tank and stores it in the relay water tank (high ground). Normally, the relay water tank is provided between the building 110 and the building 120 shown in FIG. 1, but in this case, an embedded section of the water supply pipe from the water receiving tank 112 to the relay water tank, and an elevated position on the building 120 from the relay water tank. The embedded section of the water supply pipe up to the water tank 122 becomes a new detection target. In addition, in a facility having the same size of the building 120 and the building 140, the elevated water tank is provided in both the building 120 and the building 140. In this case, the embedded sections of the two water supply pipes from the electric pump 114 of the water receiving tank 112 to the two elevated water tanks on the building 120 and the building 140 are to be detected.
図２は、本発明の杭構造体２２０が設置された埋込配管構造を示す側面図である。図２は、埋込給水配管の直管の継手部分に設けられた杭構造体２２０を示す。なお、図２は、埋込給水配管に並行かつ地盤に対し垂直な面における側面図を示す。図２に示す埋込配管構造２００では、地盤２０２に掘られた埋設溝に給水配管２０６，２１０が設けられ、その埋設溝が良質な埋設土砂２０４で埋め戻されている。給水配管２０６および給水配管２１０は、継手部２０８により接続され、図２の埋込配管構造２００では、この継手部２０８に対応して、その上方の地上に本発明の杭構造体２２０が設けられている。必ずしも継手部に対応して杭構造体２２０を設けることを要さないが、地震後の詳細な調査結果から、このような配管の継手部に多くの漏水が発生していることが判明しているため、本発明の杭構造体２２０は、埋込給水配管の継手の部分に優先的に設けられることが好ましい。また、給水配管は、特に限定されるものではなく、鋼管、塩化ビニル管、フレキシブル配管などの如何なる配管材料を用いて構成することができる。しかしながら、フレキシブル配管は耐震性に優れるため、本発明の杭構造体２２０は、既設の鋼管や塩化ビニル管の震災対策として好適に設置することができる。 FIG. 2 is a side view showing an embedded piping structure in which the pile structure 220 of the present invention is installed. FIG. 2 shows a pile structure 220 provided at the joint portion of the straight pipe of the embedded water supply pipe. In addition, FIG. 2 shows a side view in a plane parallel to the embedded water supply pipe and perpendicular to the ground. In the embedded pipe structure 200 shown in FIG. 2, water supply pipes 206 and 210 are provided in the embedded grooves dug in the ground 202, and the embedded grooves are backfilled with high quality embedded soil 204. The water supply pipe 206 and the water supply pipe 210 are connected by a joint 208, and in the embedded pipe structure 200 of FIG. 2, the pile structure 220 of the present invention is provided above the ground corresponding to the joint 208. ing. Although it is not always necessary to provide the pile structure 220 corresponding to the joint part, it has been found from the detailed investigation results after the earthquake that a lot of water leaks in the joint part of such a pipe. Therefore, the pile structure 220 of the present invention is preferably provided preferentially at the joint portion of the embedded water supply pipe. Further, the water supply pipe is not particularly limited, and can be configured using any pipe material such as a steel pipe, a vinyl chloride pipe, a flexible pipe, and the like. However, since flexible piping is excellent in earthquake resistance, the pile structure 220 of the present invention can be suitably installed as an earthquake countermeasure for existing steel pipes and vinyl chloride pipes.
給水配管２０６，２１０および継手部２０８の周囲には、これら給水配管等から漏水が発生した場合に漏れ出た水を地上に導く導水路Ｇが形成されている。導水路Ｇは、本実施形態の外部流路を構成する。図２に示す杭構造体２２０は、その杭本体の先端部分に取水口２２２が開口し、杭本体内部を通って杭の頭部から漏水が放出される構造とされている。図２に示す場合において導水路Ｇは、給水配管２０６，２１０および継手部２０８を囲繞し、かつ杭構造体２２０へ水を導くようにＴ字状に分岐した、Ｔ字管状のシート部材２２４から構成されている。シート部材２２４は、例えばポリエチレン（ＰＥ）、ポリプロピレン（ＰＰ）、塩化ビニル（ＰＶＣ）、ポリスチレン（ＰＳ）、ポリ（アクリロニトリル・ブタジエン・スチレン）（ＡＢＳ）、ポリメチルメタアクリレート（ＰＭＭＡ）、エチレンビニルアセテート（ＥＶＡ）ポリエチレンテレフタラート（ＰＥＴ）などのプラスチックシートを用いて構成することができ、特に限定されるものではない。 Around the water supply pipes 206 and 210 and the joint portion 208, there is formed a water conduit G that guides the leaked water to the ground when water leaks from these water supply pipes. The water conduit G constitutes the external flow path of the present embodiment. The pile structure 220 shown in FIG. 2 has a structure in which a water intake port 222 is opened at the tip of the pile body, and water leaks from the head of the pile through the inside of the pile body. In the case shown in FIG. 2, the water guide channel G surrounds the water supply pipes 206 and 210 and the joint portion 208 and branches from the T-shaped sheet member 224 branched in a T shape so as to guide water to the pile structure 220. It is configured. The sheet member 224 is made of, for example, polyethylene (PE), polypropylene (PP), vinyl chloride (PVC), polystyrene (PS), poly (acrylonitrile butadiene styrene) (ABS), polymethyl methacrylate (PMMA), ethylene vinyl acetate. (EVA) It can comprise using plastic sheets, such as a polyethylene terephthalate (PET), It does not specifically limit.
シート部材２２４は、給水配管２０６，２１０および継手部２０８の周囲を取り巻く部分の両端において締結バンド２２６ａ，２２６ｂにより締結され、漏水検知の範囲が画定される。また杭構造体２２０の頭部は、締結バンド２２８で締結され、上記締結バンド２２６ａ，２２６ｂとともに、漏れ出た水が杭本体の取水口２２２を通って杭構造体２２０の頭部から放出されるように構成されている。上記構成により、漏水の目印となる水の放出が明瞭となり、かつ漏水によって埋込給水配管から失われる水量も低減されることとなる。 The sheet member 224 is fastened by fastening bands 226a and 226b at both ends of portions surrounding the water supply pipes 206 and 210 and the joint portion 208, and the range of water leakage detection is defined.

With the above-described configuration, the release of water that becomes a marker of water leakage becomes clear, and the amount of water lost from the embedded water supply pipe due to water leakage is also reduced.
シート部材２２４の給水配管周りの部分の側面には、例えばチャック２２４ａが給水配管の延びる方向に沿って設けられ、給水配管等の周囲にシート部材２２４を設置する際の作業を容易なものとしている。なお図２の図面上では、説明の簡単のため導水路Ｇは埋設土砂２０４を排して水路を形成しているように模式的に示されているが、一定の水圧下において水が杭構造体２２０の取水口２２２に導かれる程度の流路が確保されればよい。また、所定間隔で杭構造体２２０を設置し、埋込給水配管の全体をもれなくカバーするように施工することもできるが、費用対効果の観点からは、継手部分などの特に漏水の発生する蓋然性の高い箇所に優先的に設け、他の直管部分については好適に省略することができる。なお、シート部材は、本実施形態の外部流路形成手段を構成する。 For example, a chuck 224a is provided on the side surface of the portion around the water supply pipe of the sheet member 224 along the direction in which the water supply pipe extends, thereby facilitating work when the sheet member 224 is installed around the water supply pipe or the like. . In the drawing of FIG. 2, for the sake of simplicity of explanation, the water guide channel G is schematically shown as forming a water channel by removing the buried earth and sand 204, but water is pile structure under a certain water pressure. It is only necessary to secure a flow path that is guided to the water intake port 222 of the body 220. In addition, it is possible to install the pile structures 220 at predetermined intervals and to cover the entire embedded water supply pipe without fail, but from the viewpoint of cost-effectiveness, the probability of occurrence of water leakage particularly in the joint portion, etc. It is possible to preferentially omit the other straight pipe portion by providing it preferentially at a high location. The sheet member constitutes the external flow path forming means of the present embodiment.

以下、本発明の感震発光センサ３５０の構成について説明する。本発明の感震発光センサ３５０は、設定の強度以上の振動を検知する振動検知手段と、振動が検知された場合に発光する発光手段とを備えている。振動検知手段は、落球式感震器、倒立棒式感震器、水銀式感震器、摩擦式感震器など種々の機械式の感震機構、または光学式振動センサ、渦電流式センサ、容量型センサ等の電気式の感震機構を採用することができる。メンテナンスの容易性、動作の信頼性および確実性、杭構造体２２０が風雨に晒されるという観点からは、機械式のものが好適に用いられ、落球式のものがより好適に用いられる。 Hereinafter, the configuration of the seismic light-emitting sensor 350 of the present invention will be described. The seismic light-emitting sensor 350 of the present invention includes vibration detecting means for detecting vibrations having a set intensity or higher and light emitting means for emitting light when vibrations are detected. The vibration detection means can be any of a variety of mechanical seismic mechanisms such as a falling ball type seismic device, an inverted bar type seismic device, a mercury type seismic device, a friction type seismic device, an optical vibration sensor, an eddy current sensor, An electric seismic mechanism such as a capacitive sensor can be employed. From the viewpoint of ease of maintenance, operational reliability and reliability, and the pile structure 220 being exposed to wind and rain, a mechanical type is preferably used, and a falling ball type is more preferably used.

From the viewpoint that the pile structure 220 is exposed to wind and rain, it is preferable to use a chemiluminescent material that does not easily cause problems such as electrical contact. When an electroluminescent element is used, the mechanical or electrical seismic mechanism and the switch can be linked to connect an electrical contact to the electroluminescent element in response to the operation of the seismic mechanism. . When a chemiluminescent material is used, the mechanical or electrical seismic mechanism and other mechanical mechanisms are linked to cause mixing of the chemiluminescent material solution in response to the operation of the seismic mechanism. It can be configured. For example, it can be a mechanism in which the lock etc. is released by the operation of the seismic mechanism and mechanical force acts on the chemiluminescent material to break the ampoule inside the dual structure chemiluminescent material and cause mixing of the solution .

センサ筐体本体部３５２の底部には、支柱３６２を略中央に備えるバネ台座３６０が設けられ、この支柱３６２を摺動自在に嵌装する孔が設けられたプランジャ３６４が、この支柱３６２に取り付けられ、上下に移動可能とされている。プランジャ３６４は、つば部３６４ａを備え、つば部３６４ａとバネ台座３６０との間には、プランジャ３６４の下側部分および支柱３６２に巻回するように圧縮バネ３６６が設けられ、この圧縮バネ３６６によりプランジャ３６４に対し上向きの力が作用している。 At the bottom of the sensor housing body 352, a spring pedestal 360 having a support column 362 at the approximate center is provided, and a plunger 364 provided with a hole for slidably fitting the support column 362 is attached to the support column 362. It can be moved up and down. The plunger 364 includes a collar portion 364 a, and a compression spring 366 is provided between the collar portion 364 a and the spring base 360 so as to be wound around the lower portion of the plunger 364 and the column 362. An upward force is acting on the plunger 364.
センサ筐体本体部３５２のバネ台座３６０上には、鋼球３７０を支持し、所定の曲率半径および面積を有する皿部３６８ａが形成された鋼球台座３６８がさらに設けられている。皿部３６８ａの曲率半径および広さは、鋼球の質量および目標の振動強度等を勘案し、目標の振動強度に応答して鋼球３７０が皿部３６８ａから落球するように設計される。また、皿部３６８ａの底には上記プランジャ３６４を垂直方向に挿通させる貫通孔３６８ｂが形成され、さらに鋼球台座３６８の貫通孔３６８ｂの略中央部下側には、上述した圧縮バネ３６６、プランジャ３６４の少なくともつば部３６４ａ以下の部分を収容するための空間が設けられている。 On the spring pedestal 360 of the sensor housing body 352, a steel ball pedestal 368 that supports the steel ball 370 and has a dish 368a having a predetermined radius of curvature and area is further provided. The radius of curvature and the width of the dish portion 368a are designed such that the steel ball 370 falls from the dish portion 368a in response to the target vibration strength in consideration of the mass of the steel ball and the target vibration strength. Further, a through hole 368b through which the plunger 364 is inserted in the vertical direction is formed at the bottom of the plate portion 368a, and further, the compression spring 366 and the plunger 364 described above are located substantially below the center of the through hole 368b of the steel ball base 368. A space for accommodating at least a portion of the flange portion 364a or less is provided.
振動を検知する前の作動前の状態では、プランジャ３６４は、その先端を皿部３６８ａ上の鋼球３７０に当接させ、鋼球３７０の重みにより皿部３６８ａ以下の位置まで押しさげられ、これにより圧縮バネ３６６に弾性エネルギーが蓄勢されている。地震等に起因する振動を受けて鋼球３７０が皿部３６８ａから落球すると、プランジャ３６４は、鋼球３７０の重みから解放され、圧縮バネ３６６の伸張とともに上方に押し上げられる。すなわち、バネ台座３６０、支柱３６２、プランジャ３６４、圧縮バネ３６６、鋼球台座３６８、鋼球３７０が本実施形態の感震発光センサ３５０Ａの感震機構を構成している。 In the state before the operation before detecting the vibration, the plunger 364 has its tip abutted against the steel ball 370 on the plate portion 368a, and is pushed to a position below the plate portion 368a by the weight of the steel ball 370. Thus, elastic energy is stored in the compression spring 366. When the steel ball 370 falls from the plate portion 368a due to vibration caused by an earthquake or the like, the plunger 364 is released from the weight of the steel ball 370 and is pushed upward as the compression spring 366 extends. That is, the spring pedestal 360, the column 362, the plunger 364, the compression spring 366, the steel ball pedestal 368, and the steel ball 370 constitute a seismic mechanism of the seismic light emitting sensor 350A of this embodiment.
センサ筐体上段部３５４は、チューブ状の化学発光材料３７６を収容し、この化学発光材料３７６を受ける第１の底部３５４ａを備える。センサ筐体上段部３５４は、さらに、その第１の底部３５４ａの略中央を通りくぼみまたは溝が設けられ、略中央に開口部３５４ｃが設けられる第２の底部３５４ｂが形成されている。第２の底部３５４ｂを含むくぼみには、台形ないし三角形状の突出部を有する下側押板３７２が落とし込まれている。なお、台形ないし三角形状の斜面が切り出される方向は、図８に示すように、チューブ状の化学発光材料３７６の長手方向と垂直な方向である。このくぼみに落とし込まれた下側押板３７２は、地震等により鋼球３７０が落球し感震機構が作動状態となった際に、上記開口部３５４ｃを介してプランジャ３６４からの力を受け、くぼみまたは溝の側面に沿って押し上げられる。そして、下側押板３７２の突出部は、化学発光材料３７６の中央部分に当接し、プランジャ３６４から作用する力を受けて化学発光材料３７６に伝達する。 The sensor casing upper step 354 includes a first bottom portion 354 a that houses a tube-shaped chemiluminescent material 376 and receives the chemiluminescent material 376. The sensor casing upper step 354 is further provided with a recess or a groove passing through substantially the center of the first bottom 354a, and a second bottom 354b in which an opening 354c is provided in the substantially center. A lower push plate 372 having a trapezoidal or triangular protrusion is dropped into the recess including the second bottom 354b. The direction in which the trapezoidal or triangular slope is cut out is a direction perpendicular to the longitudinal direction of the tube-shaped chemiluminescent material 376, as shown in FIG. The lower push plate 372 dropped into the recess receives a force from the plunger 364 through the opening 354c when the steel ball 370 drops due to an earthquake or the like and the seismic mechanism is activated. Pushed up along the side of the indentation or groove. The protruding portion of the lower push plate 372 contacts the central portion of the chemiluminescent material 376 and receives the force acting from the plunger 364 and transmits it to the chemiluminescent material 376.
化学発光材料３７６上には、略中央を通りくぼみまたは溝を有する上側押板３７４が配置されている。この上側押板３７４は、上記化学発光材料３７６の両端側に当接し、対向する第１の底部３５４ａとともに化学発光材料３７６の両端を挟持する。上記上側押板３７４の略中央を通って設けられたくぼみまたは溝は、化学発光材料３７６が下側押板３７２により押し上げられた際に発生する変形を受容する。 On the chemiluminescent material 376, an upper push plate 374 having a depression or groove passing through substantially the center is disposed. The upper push plate 374 is in contact with both ends of the chemiluminescent material 376 and sandwiches both ends of the chemiluminescent material 376 together with the first bottom portion 354a facing each other. The indentation or groove provided through substantially the center of the upper push plate 374 receives deformation that occurs when the chemiluminescent material 376 is pushed up by the lower push plate 372.
図８に示す化学発光材料３７６は、いわゆるケミカルライトとして構成され、蛍光溶液がガラス製のアンプルに封入され、そのアンプルとともに酸化溶液が樹脂製のチューブに挿入された二重構造を有する。化学発光材料３７６に力が作用して変形し、内部のアンプルが破壊されると、アンプル内の蛍光溶液とチューブ内の酸化溶液とが混合し、蛍光を発する。アンプルの強度は、鋼球３７０の質量や圧縮バネ３６６のバネ定数や他の部材の質量等を考慮し、圧縮バネ３６６に蓄勢された弾性エネルギーにより充分に破壊される程度に調整されていればよい。また、化学発光材料３７６は、夜間にわたって発光することが好ましいため、８〜１０時間程度の発光時間が得られるよう蛍光材料や構造が設計されることが好ましい。また、上側押板３７４およびセンサ筐体蓋部３５６は、化学発光材料３７６が発する蛍光が外部に放射されるように、少なくとも化学発光材料３７６に対応する部分がアクリルや強化ガラス等の光透過性の材料で構成されている。 The chemiluminescent material 376 shown in FIG. 8 is configured as a so-called chemical light, and has a double structure in which a fluorescent solution is sealed in a glass ampule and an oxidizing solution is inserted into a resin tube together with the ampule. When a force is applied to the chemiluminescent material 376 and deformed to destroy the internal ampule, the fluorescent solution in the ampule and the oxidizing solution in the tube are mixed to emit fluorescence. The strength of the ampoule is adjusted to such an extent that it can be sufficiently destroyed by the elastic energy stored in the compression spring 366 in consideration of the mass of the steel ball 370, the spring constant of the compression spring 366, the mass of other members, and the like. That's fine. Further, since the chemiluminescent material 376 preferably emits light at night, the fluorescent material and the structure are preferably designed so as to obtain a light emission time of about 8 to 10 hours. The upper push plate 374 and the sensor housing cover 356 have at least a portion corresponding to the chemiluminescent material 376 such as acrylic or tempered glass so that the fluorescence emitted from the chemiluminescent material 376 is emitted to the outside. Consists of materials.
図９は、地震により落球した後の作動後の感震発光センサ３５０の状態を示す図である。図９に示すように、地震等に起因する振動を受けて鋼球３７０が皿部３６８ａから落球すると、プランジャ３６４が鋼球３７０の重みから解放され、圧縮バネ３６６の伸張とともに上方に押し上げられる。そして、プランジャ３６４が下側押板３７２に当接し、下側押板３７２を押し上げ、これにより上側押板３７４と下側押板３７２とに挟み込まれていた化学発光材料は、その両端部の挟持と下側押板３７２の台形形状の突出部の押し出しにより曲げ変形を受け、上記上側押板３７４の略中央を通り設けられたくぼみまたは溝がこの曲げ変形を受容する。この曲げ変形により内部のアンプルが破壊され、発光を開始する。 FIG. 9 is a diagram illustrating a state of the seismic light-emitting sensor 350 after operation after the ball is dropped due to an earthquake. As shown in FIG. 9, when the steel ball 370 falls from the dish portion 368 a in response to vibration caused by an earthquake or the like, the plunger 364 is released from the weight of the steel ball 370 and is pushed upward as the compression spring 366 extends. Then, the plunger 364 comes into contact with the lower push plate 372 and pushes up the lower push plate 372, so that the chemiluminescent material sandwiched between the upper push plate 374 and the lower push plate 372 is sandwiched between both ends thereof. And a depression or groove provided through substantially the center of the upper push plate 374 receives the bending deformation. This bending deformation destroys the internal ampule and starts light emission.
以上説明した化学発光材料および落球式感震機構を採用する感震発光センサ３５０Ａによれば、目標強度を越えた振動が発生すると、その振動を検知し、機械的な機構により溶液の混合が起こり化学発光反応が開始される。感震発光センサ３５０Ａの上面から光が放射され、図６または図７に示す杭構造体の頭部３００の上面から光が放射されることとなる。図８および図９に示す感震発光センサ３５０Ａは、機械式感震機構が構成され、化学発光を用いて発光手段が構成されているため、上述したようにメンテナンスの容易性、動作の信頼性および確実性、杭構造体２２０が風雨に晒されるという観点から好適に用いることができる。なお、図示していないが、センサの運搬および設置の容易のため、鋼球３７０の位置の固定と固定解除を行うロック機構を適宜備えることができる。 According to the seismic light emitting sensor 350A employing the chemiluminescent material and the falling ball type seismic mechanism described above, when vibration exceeding the target intensity occurs, the vibration is detected and mixing of the solution occurs by the mechanical mechanism. A chemiluminescent reaction is initiated. Light is emitted from the upper surface of the seismic light-emitting sensor 350A, and light is emitted from the upper surface of the head 300 of the pile structure shown in FIG. 6 or FIG. The seismic light emitting sensor 350A shown in FIGS. 8 and 9 has a mechanical seismic mechanism and a light emitting means using chemiluminescence. Therefore, as described above, ease of maintenance and operational reliability are provided. And it can use suitably from a viewpoint that reliability and the pile structure 220 are exposed to a wind and rain. Although not shown, a lock mechanism for fixing and releasing the position of the steel ball 370 can be provided as appropriate for easy transport and installation of the sensor.
以下、図１０を参照して、本発明の感震発光センサの他の構成について詳細を説明する。図１０は、本発明の感震発光センサの第２の実施形態を示す概略図である。図１０（Ａ）は、作動前を示し、図１０（Ｂ）は、地震等が発生した作動後を示す。なお、図１０に示す感震発光センサ３５０Ｂは、落球式の感震機構とスイッチを連携させ、感震機構の作動に応答して電気発光素子への電気接点を接続する構成とされている場合の実施形態を示す。 Hereinafter, with reference to FIG. 10, another configuration of the seismic light-emitting sensor of the present invention will be described in detail. FIG. 10 is a schematic view showing a second embodiment of the seismic light-emitting sensor of the present invention. FIG. 10A shows the state before the operation, and FIG. 10B shows the state after the operation in which an earthquake or the like occurs. Note that the seismic light-emitting sensor 350B shown in FIG. 10 is configured to connect the electric contact to the electroluminescent element in response to the operation of the seismic mechanism by linking the falling ball type seismic mechanism and the switch. The embodiment of is shown.
図１０（Ａ）に示す感震発光センサ３５０Ｂは、鋼球３８０と、内部に鋼球３８０を収容し、所定のスロープが形成された容器３８２と、鋼球３８０の位置に対応して動作する第１の動作板３８４と、第２の動作板３８６と、電気接点３８８と、電気発光素子３９４とを含んで構成される。第１の動作板３８４および第２の動作板３８６には、それぞれバネ３９０およびバネ３９２が設けられ、これらにより押し上げる力が作用している。第２の動作板３８６および電気接点３８８は、スイッチを構成し、地震発生前の段階では、鋼球３８０が第１の動作板３８４を押し下げ、さらに第１の動作板３８４が第２の動作板３８６を押し下げているため、スイッチは切断された状態となっている。 The seismic light-emitting sensor 350B shown in FIG. 10A operates in accordance with the position of the steel ball 380, the container 382 in which the steel ball 380 is housed and a predetermined slope is formed, and the steel ball 380. A first operation plate 384, a second operation plate 386, an electrical contact 388, and an electroluminescent element 394 are configured. The first operating plate 384 and the second operating plate 386 are provided with a spring 390 and a spring 392, respectively, and a pushing force is applied thereto. The second operation plate 386 and the electrical contact 388 constitute a switch, and in the stage before the occurrence of the earthquake, the steel ball 380 pushes down the first operation plate 384, and the first operation plate 384 is the second operation plate. Since 386 is depressed, the switch is in a disconnected state.
所定強度の地震が発生し、鋼球３８０が容器３８２内を転がって移動すると、図１０（Ｂ）に示されるように、鋼球３８０の重みで圧縮されていたバネ３９０が伸びて、第１の動作板３８４を押し上げる。また第２の動作板３８６にかかる第１の動作板３８４の押さえが緩和されるため、バネ３９２が伸びて第２の動作板３８６も押し上げられ、第２の動作板３８６および電気接点３８８が接触してスイッチが切り替わる。これにより、電気発光素子３９４に電気が通電して発光する。 When an earthquake of a predetermined intensity occurs and the steel ball 380 rolls and moves in the container 382, the spring 390 compressed by the weight of the steel ball 380 extends as shown in FIG. The operation plate 384 is pushed up. Further, since the pressing of the first operation plate 384 on the second operation plate 386 is relaxed, the spring 392 is extended and the second operation plate 386 is also pushed up, so that the second operation plate 386 and the electrical contact 388 are in contact with each other. Then the switch changes. Thereby, electricity is supplied to the electroluminescent element 394 to emit light.
なお、図１０に示す感震発光センサ３５０Ｂの各要素は、感震発光センサの第１の実施形態と同様に、適切なセンサ筐体内に収容される。この場合、杭構造体が風雨に晒されるという観点からは、電気的接触等の問題の問題を引き起こさないよう、筐体内部が適切なシール材料で密閉されていることが好ましい。 In addition, each element of the seismic light emission sensor 350B shown in FIG. 10 is accommodated in a suitable sensor housing | casing similarly to 1st Embodiment of a seismic light emission sensor. In this case, from the viewpoint that the pile structure is exposed to wind and rain, the inside of the housing is preferably sealed with an appropriate sealing material so as not to cause problems such as electrical contact.
以上説明したように、上記実施形態によれば、埋設配管の埋込位置および漏水箇所を容易かつ迅速に特定可能とし、かつ夜間に発生した震災にも対応可能な杭構造体を含む埋込配管構造、該杭構造体および該杭構造体の地盤への施工方法を提供することができる。 As described above, according to the above embodiment, the embedding position including the pile structure that can easily and quickly identify the embedding position and the water leakage location of the buried piping and can cope with the earthquake disaster that occurred at night. A piping structure, a pile structure, and a construction method of the pile structure on the ground can be provided.
本発明の埋込配管構造は、所定強度の地震に感応して発光し、埋込配管から漏れ出した水などの流体を頭部から放出する杭構造体を備えるため、埋設配管の埋込位置を夜間であっても容易かつ早期に識別可能とされ、かつ当該杭構造体の検知範囲において漏水が発生しているか否かを容易に判断することが可能とされている。また、これらの判断には、作業者の熟練等を必要とせず、漏水箇所の特定が困難な砂地地盤等であっても好適に漏水の発生を検知することが可能となる。したがって、震災直後からの貯水槽水道の早期復旧に貢献することができる。これにより、震災時の医療用水や生活用水の確保が容易なものとなる。 Since the embedded piping structure of the present invention includes a pile structure that emits light in response to an earthquake of a predetermined intensity and discharges fluid such as water leaking from the embedded piping from the head, the embedded position of the embedded piping Can be easily and early identified even at night, and it is possible to easily determine whether or not water leakage has occurred in the detection range of the pile structure. Further, these determinations do not require the skill of an operator, and it is possible to suitably detect the occurrence of water leakage even in sandy ground or the like where it is difficult to identify a water leakage location. Therefore, it can contribute to the early restoration of the water tank water supply immediately after the earthquake. This makes it easy to secure medical water and domestic water at the time of the earthquake.
なお、上述までは、水道水の給水配管に杭構造体を適用する場合の実施形態について説明してきたが、本発明の漏洩の検知対象の流体は水道水に限定されるものではない。例えば、プロパンガスや都市ガスなどのガス配管に適用することで、ガス配管から漏れ出たガスを地表近傍まで導き、地上でガスセンサ等を用いて容易にガスの漏洩箇所を把握できるようにすることもできる。 In addition, although the embodiment in the case where a pile structure is applied to the tap water supply pipe has been described so far, the leakage detection target fluid of the present invention is not limited to tap water. For example, by applying it to gas pipes such as propane gas and city gas, the gas leaked from the gas pipe can be guided to the vicinity of the ground surface, and the gas leak point can be easily grasped on the ground using a gas sensor etc. You can also.
上述したように本発明の埋込配管構造は、埋込配管の位置および漏水箇所の識別性を向上し、地震等の災害時の給水配管の被害状況を迅速に把握することが可能となるため、病院等の災害弱者施設や避難所等の施設の震災対策として施工することができる。 As described above, the embedded piping structure of the present invention improves the identification of the position of the embedded piping and the location of the water leakage, and can quickly grasp the damage status of the water supply piping during a disaster such as an earthquake. It can be constructed as a disaster countermeasure for facilities such as hospitals and other vulnerable facilities and shelters.
これまで本発明の実施形態について説明してきたが、本発明の実施形態は上述した実施形態に限定されるものではなく、他の実施形態、追加、変更、削除など、当業者が想到することができる範囲内で変更することができ、いずれの態様においても本発明の作用・効果を奏する限り、本発明の範囲に含まれるものである。 Although the embodiments of the present invention have been described so far, the embodiments of the present invention are not limited to the above-described embodiments, and those skilled in the art may conceive other embodiments, additions, modifications, deletions, and the like. It can be changed within the range that can be done, and any embodiment is included in the scope of the present invention as long as the effects of the present invention are exhibited.
