Description

本発明は、管路の内部を流れる水と熱交換を行うための熱交換部材と、この熱交換部材を管路に敷設するための施工方法と、に関するものである。   The present invention relates to a heat exchanging member for exchanging heat with water flowing in a pipe, and a construction method for laying the heat exchanging member on the pipe.

内部に水が流れる管路として、下水道用の管路や工業用水用の管路或いは農業用水用の管路、等が敷設されている。これらの管路の内部を流れる水の温度は四季を通して大きく変動することがなく、略一定の値を保持している。例えば、下水道用の管路を流れる水の温度は、夏季にあっては外気温度よりも低く、冬季にあっては外気温度よりも高い。このため、管路の内部を流れる水との温度差を利用した熱交換を行うことで新たなエネルギー源とすることが考えられる。   As pipes through which water flows, pipes for sewers, pipes for industrial water, pipes for agricultural water, and the like are laid. The temperature of the water flowing inside these pipes does not fluctuate greatly throughout the four seasons and maintains a substantially constant value. For example, the temperature of water flowing through a sewer pipe is lower than the outside air temperature in summer and higher than the outside air temperature in winter. For this reason, it can be considered that a new energy source is obtained by performing heat exchange using a temperature difference with water flowing inside the pipe.

例えば、特許文献1に記載された発明は、下水熱採熱設備と下水熱利用システムに関するものである。この発明では、採熱設備は下水道管の外周のうち少なくとも上方を被覆するジャケット状に配設されており、この採熱設備は、熱原水が通流し高熱伝導率材料で形成された採熱管と、採熱管の間隙及び周囲に充填された保護材とを有している。また採熱管は、下水道管の長手方向に平行に複数配設された直管と、直管同士を接続するベント管によって構成されている。   For example, the invention described in Patent Document 1 relates to a sewage heat collection facility and a sewage heat utilization system. In the present invention, the heat collecting equipment is arranged in a jacket shape covering at least the upper part of the outer periphery of the sewer pipe, and this heat collecting equipment comprises a heat collecting pipe formed of a high thermal conductivity material through which the heat source water flows. , And a protective material filled in and around the gap of the heat collection tube. Further, the heat collecting pipe is constituted by a plurality of straight pipes arranged in parallel to the longitudinal direction of the sewer pipe and a vent pipe connecting the straight pipes.

上記の如く構成された採熱設備では、採熱管が下水道管の外周に配設される。このため、採熱管が下水に直接接触することがないため、メンテナンスが不要となり維持コストが低減できるという効果を有する。また、既設の下水道管に設置する場合には、周囲の地盤を掘削して開放した下水道管の外周に採熱管を配設すると共に、所定の部位に保護材を充填することで良く、工事が容易であるという効果も有する。   In the heat collecting equipment configured as described above, the heat collecting pipe is disposed on the outer periphery of the sewer pipe. For this reason, since a heat collection pipe does not contact sewage directly, it has an effect that maintenance is unnecessary and maintenance cost can be reduced. In addition, when installing in an existing sewer pipe, it is sufficient to install a heat collecting pipe on the outer periphery of the sewer pipe opened by excavating the surrounding ground and to fill a predetermined part with a protective material. It also has the effect of being easy.

特許文献1に記載された発明は上記の如き特徴を有する。しかし、下水道管を介して下水の熱を取得するため、下水の熱を充分に利用し得ない虞がある。   The invention described in Patent Document 1 has the characteristics as described above. However, since the heat of the sewage is acquired through the sewer pipe, there is a possibility that the heat of the sewage cannot be fully utilized.

本発明の目的は、管路の内部を流れる水との熱交換を円滑に行えるようにした熱交換部材を提供すると共に、該熱交換部材を管路に敷設するための施工方法を提供することにある。   An object of the present invention is to provide a heat exchange member capable of smoothly exchanging heat with water flowing inside a pipeline, and to provide a construction method for laying the heat exchange member in the pipeline. It is in.

上記課題を解決するために本発明に係る熱交換部材は、太さ方向に隣接して設けられた熱交換媒体が流通する複数の流通路を有すると共に可撓性を有する長尺状の部材からなり、水が流れる管路の内周面に、該管路を流れる水と直接又は間接的に接触し得るように配置されることで、管路を流れる水と流通路を流通する熱交換媒体との熱交換を行うように構成されるものである。   In order to solve the above-mentioned problems, a heat exchange member according to the present invention has a plurality of flow passages through which a heat exchange medium provided adjacent to each other in the thickness direction flows, and is a long member having flexibility. The heat exchange medium that circulates through the flow path and the water flowing through the pipe by being arranged on the inner peripheral surface of the pipe through which the water flows so as to be in direct or indirect contact with the water flowing through the pipe It is comprised so that heat exchange may be performed.

上記熱交換部材に於いて、前記熱交換部材が、熱交換媒体が流通する流通路を構成する複数の可撓性を有する筒体を該筒体の太さ方向に並列させ、前記並列させた複数の筒体を可撓性を有する連結部材によって一体化させると共に、長さ方向の両端に前記並列させた複数の筒体を開口させたものであることが好ましい。   In the heat exchange member, the heat exchange member has a plurality of flexible cylinders constituting a flow path through which a heat exchange medium flows arranged in parallel in the thickness direction of the cylinder, and the parallel arrangement is performed. It is preferable that the plurality of cylinders are integrated by a flexible connecting member and the plurality of cylinders arranged in parallel are opened at both ends in the length direction.

また、前記熱交換部材が、可撓性を有する長尺状の本体部材の内部に、熱交換媒体が流通する複数の流通路が長手方向に貫通すると共に該流通路の太さ方向に隣接して形成され、前記本体部材の長手方向の両端に前記流通路を開口させたものであることが好ましい。   In addition, the heat exchange member has a plurality of flow passages through which the heat exchange medium circulates in the longitudinal direction inside the elongated main body member having flexibility, and is adjacent to the thickness direction of the flow passage. It is preferable that the flow passage is opened at both ends in the longitudinal direction of the main body member.

また、上記何れかの熱交換部材に於いて、少なくとも管路を流れる水と対向する面には可撓性を有する金属が配されていることが好ましい。   In any of the above heat exchange members, it is preferable that a metal having flexibility is disposed on at least a surface facing water flowing through the pipe.

また本発明に係る熱交換部材を敷設するための施工方法は、上記何れかの熱交換部材を敷設するための施工方法であって、水が流れる管路の長手方向に、該管路の内周面に沿って上記何れかの熱交換部材を配置し、前記熱交換部材が配置された管路の内部に、可撓性を有するスリーブを、該スリーブの外周面が管路の内周面又は前記熱交換部材に干渉することがないように縮径して挿入し、その後、挿入されたスリーブを復元させて該スリーブの外周面と管路の内周面とによって前記熱交換部材を挟み込むことを特徴とするものである。   The construction method for laying the heat exchange member according to the present invention is a construction method for laying any one of the heat exchange members described above, and is arranged in the longitudinal direction of the pipeline through which water flows. Any one of the above heat exchange members is disposed along the peripheral surface, a flexible sleeve is disposed inside the pipe line in which the heat exchange member is disposed, and the outer peripheral surface of the sleeve is the inner peripheral surface of the pipe line. Alternatively, the diameter of the sleeve is reduced and inserted so as not to interfere with the heat exchange member, and then the inserted sleeve is restored and the heat exchange member is sandwiched between the outer peripheral surface of the sleeve and the inner peripheral surface of the pipe. It is characterized by this.

また本発明に係る他の熱交換部材を敷設するための施工方法は、水が流れる内周面が硬化した合成樹脂管からなる管路に上記何れかの熱交換部材を敷設するための施工方法であって、水が流れる管路の長手方向に、該管路の内周面に沿って上記何れかの熱交換部材を配置し、前記熱交換部材を構成する連結部材と、管路の内周面を構成する硬化した合成樹脂管と、を接着又は融着或いは溶接によって一体化させることを特徴とするものである。   The construction method for laying another heat exchange member according to the present invention is a construction method for laying any one of the above heat exchange members in a pipe line made of a synthetic resin pipe whose inner peripheral surface through which water flows is cured. In the longitudinal direction of the pipeline through which water flows, any one of the above heat exchange members is arranged along the inner peripheral surface of the pipeline, and the connecting member constituting the heat exchange member, The cured synthetic resin tube constituting the peripheral surface is integrated by adhesion, fusion, or welding.

本発明に係る熱交換部材は、太さ方向に隣接して設けられた熱交換媒体が流通する複数の流通路を有すると共に可撓性を有する長尺状の部材によって構成される。このため、熱交換部材が、水が流れる管路の内周面に、該管路を流れる水と直接又は間接的に接触し得るように配置されることで、管路を流れる水と流通路を流通する熱交換媒体との熱交換を行うことができる。   The heat exchange member according to the present invention includes a plurality of flow passages through which heat exchange media provided adjacent to each other in the thickness direction circulate, and is configured by a long member having flexibility. For this reason, the heat exchange member is arranged on the inner peripheral surface of the pipeline through which water flows so that it can be in direct or indirect contact with the water through the pipeline, so that the water and the flow passage through the pipeline The heat exchange with the heat exchange medium that circulates can be performed.

特に、熱交換媒体が流通する流通路を構成する複数の可撓性を有する筒体を該筒体の太さ方向に並列させて可撓性を有する連結部材によって一体化させると共に、長さ方向の両端に筒体を開口させて構成した場合には、構造が簡単で、管路に対する敷設の容易な熱交換部材を構成することができる。   In particular, a plurality of flexible cylinders constituting a flow path through which the heat exchange medium flows are arranged in parallel in the thickness direction of the cylinder and integrated by a flexible connecting member, and in the length direction. When the cylindrical body is opened at both ends, a heat exchange member that has a simple structure and can be easily laid on the pipe line can be formed.

また、可撓性を有する長尺状の本体部材の内部に、熱交換媒体が流通する複数の流通路が長手方向に貫通すると共に該流通路の太さ方向に隣接して形成され、本体部材の長手方向の両端に前記流通路を開口させた場合には、部品点数が少なく且つ管路の内周面に沿って屈曲して敷設することができる。   In addition, a plurality of flow passages through which the heat exchange medium flows penetrates in the longitudinal direction inside the elongated main body member having flexibility, and is formed adjacent to the thickness direction of the flow passage. When the flow passages are opened at both ends in the longitudinal direction, the number of parts is small, and it can be bent and laid along the inner peripheral surface of the pipe.

また、上記何れかの熱交換部材に於いて、少なくとも管路を流れる水と対向する面に可撓性を有する金属が配されていることによって、管路を流れる水と熱交換媒体との熱の交換を効率良く行うことができる。また、管路を流れる水に対向する面が金属であることから、長期間にわたる耐久性を実現することができる。   In any one of the heat exchange members, at least the surface facing the water flowing through the pipe is provided with a flexible metal, so that the heat between the water flowing through the pipe and the heat exchange medium can be reduced. Can be exchanged efficiently. Further, since the surface facing the water flowing through the pipe is a metal, durability over a long period of time can be realized.

また本発明に係る熱交換部材を敷設するための施工方法では、管路の長手方向に且つ内周面に沿って熱交換部材を配置し、該熱交換部材が配置された管路の内部に、可撓性を有するスリーブを縮径して挿入した後、挿入されたスリーブを復元させることで、該スリーブの外周面と管路の内周面とによって熱交換部材を挟み込むことができる。このため、熱交換部材は安定した状態で管路内に敷設されることとなり、該熱交換部材を構成する複数の筒体に熱交換媒体を流通させることで、管路内を流れる水との熱交換を行うことができる。   Moreover, in the construction method for laying the heat exchange member according to the present invention, the heat exchange member is arranged in the longitudinal direction of the pipe line and along the inner peripheral surface, and inside the pipe line where the heat exchange member is arranged. After the flexible sleeve is reduced in diameter and inserted, the inserted sleeve is restored, so that the heat exchange member can be sandwiched between the outer peripheral surface of the sleeve and the inner peripheral surface of the pipe. For this reason, the heat exchange member is laid in the pipe line in a stable state, and the heat exchange medium is circulated through a plurality of cylinders constituting the heat exchange member, so that the water exchanged with the water flowing in the pipe line Heat exchange can be performed.

特に、スリーブとして、路の内周面を補修する際に用いる熱可塑性樹脂製のスリーブ、或いは熱硬化性樹脂や光硬化性樹脂を含侵させた不織布やガラス繊維製マットからなるスリーブを利用した場合には老朽化した管路の更新と同時に熱交換部材を敷設することができる。   In particular, as the sleeve, a sleeve made of a thermoplastic resin used for repairing the inner peripheral surface of the road, or a sleeve made of a nonwoven fabric or a glass fiber mat impregnated with a thermosetting resin or a photocurable resin was used. In some cases, the heat exchange member can be laid simultaneously with the renewal of the aging pipe line.

また、他の施工方法では、内周面が硬化した合成樹脂管からなる管路の長手方向に且つ内周面に沿って熱交換部材を配置し、該熱交換部材を構成する連結部材と、硬化した合成樹脂管と、を接着又は融着或いは溶接によって一体化させることで、熱交換部材を敷設することができる。この方法では、熱交換部材は直接管路を流れる水と接触することとなり、効率の良い熱交換を実現することができる。   Further, in another construction method, a heat exchange member is arranged in the longitudinal direction of the pipe line made of a synthetic resin pipe whose inner peripheral surface is cured and along the inner peripheral surface, and a connecting member constituting the heat exchange member, The heat exchange member can be laid by integrating the hardened synthetic resin tube by adhesion, fusion, or welding. In this method, the heat exchange member is in direct contact with the water flowing through the pipe line, so that efficient heat exchange can be realized.

硬化した合成樹脂管としては、管路を敷設した当初からの合成樹脂管、或いは既設の鉄筋コンクリート管からなる管路を補修した後の合成樹脂管の何れであっても、適用することができる。   As the cured synthetic resin pipe, any of a synthetic resin pipe from the beginning of laying the pipe line or a synthetic resin pipe after repairing a pipe line made of an existing reinforced concrete pipe can be applied.

以下、本発明に係る熱交換部材の構成について説明する。   Hereinafter, the structure of the heat exchange member according to the present invention will be described.

本発明に係る熱交換部材は、管路を流れる水と熱交換媒体との間で熱交換することによって、該管路を流れる水の熱を活用することを実現するためのものである。特に、本発明の熱交換部材は、管路を構成する既設管の内周面であって水が流れる部位に沿って配置されて、直接流れる水と接触し、或いは既設管の内周面を補修するライニング材を介して間接的に流れる水と接触することで水との熱交換を実現し得るように構成されている。   The heat exchange member according to the present invention is for realizing utilization of the heat of the water flowing through the pipe line by exchanging heat between the water flowing through the pipe line and the heat exchange medium. In particular, the heat exchange member of the present invention is disposed along the inner peripheral surface of the existing pipe that constitutes the pipe and the portion through which water flows, and is in contact with the directly flowing water, or the inner peripheral surface of the existing pipe. It is comprised so that heat exchange with water can be implement | achieved by contacting with the water which flows indirectly through the lining material to repair.

本発明に於いて、水が流れる管路としては、下水道用の管路、上水道用の管路、農業用水用の管路、工業用水用の管路を含む種々の水流用の管路があり、何れも好ましく適用することが可能である。特に、管路として下水道管路を利用した場合、家庭からの下水が保有する熱を活用することが可能となり、好ましい。また、管路を構成する既設管の形状は円筒形、馬蹄形、卵形、角筒形等の形状があり、何れの形状であっても適用することが可能である。   In the present invention, pipes through which water flows include various pipes for water flow including pipes for sewers, pipes for waterworks, pipes for agricultural water, and pipes for industrial water. Any of these can be preferably applied. In particular, when a sewer pipe is used as the pipe, it is possible to utilize heat retained by sewage from the home, which is preferable. Moreover, the shape of the existing pipe which comprises a pipe line has shapes, such as a cylindrical shape, a horseshoe shape, an oval shape, a rectangular tube shape, and it can apply even if it is any shape.

また、熱交換媒体としての材質を限定するものではなく、管路を流れる水の熱との間で円滑に熱交換することが可能で、且つ交換した熱をヒートポンプに伝えることが可能であれば良い。このような熱交換媒体としては、例えば水や不凍液のような液体がある。しかし、必ずしも液体に限定するものではなく、気体であっても良いことは当然である。   Moreover, the material as the heat exchange medium is not limited, and it is possible to exchange heat smoothly with the heat of water flowing through the pipe and to transmit the exchanged heat to the heat pump. good. Examples of such a heat exchange medium include liquids such as water and antifreeze. However, it is not necessarily limited to a liquid, and naturally it may be a gas.

熱交換部材は、管路に設けたマンホール間に敷設される。このため、少なくとも隣接するマンホール間の距離よりも大きい長さを有する長尺状に形成されており、ロール状に巻き付けられた状態で、保管され、且つ敷設現場まで搬送される。   The heat exchange member is laid between manholes provided in the pipeline. For this reason, it is formed in a long shape having a length that is at least larger than the distance between adjacent manholes, and is stored and transported to the laying site while being wound in a roll shape.

熱交換部材の幅寸法は、適用すべき管路に流れる水の性質や、管路の断面形状及び太さ等の条件に対応して設定される。水は該管路の底部分に沿って流れる。そして、例えば管路が下水道用の管路である場合、この管路を流れる下水の深さは太さの1/3程度に設定されているのが一般的である。このため、熱交換部材の幅寸法は、前記関係から導かれた値と等しいか或いは近似した値に設定される。   The width dimension of the heat exchange member is set in accordance with conditions such as the nature of the water flowing in the pipeline to be applied and the cross-sectional shape and thickness of the pipeline. Water flows along the bottom of the conduit. For example, when the pipe is a sewer pipe, the depth of sewage flowing through the pipe is generally set to about 1/3 of the thickness. For this reason, the width dimension of the heat exchange member is set to a value that is equal to or approximate to the value derived from the relationship.

熱交換部材を構成する筒体の数や太さは特に限定するものではなく、該熱交換部材の幅寸法や管路の太さ等の条件に応じて適宜設定されることが好ましい。例えば、管路の口径が小さい場合、筒体の太さも小さくなり、本数が大きくなる。しかし、管路の太さが大きい場合でも、筒体の太さを大きくする必要はなく、太さの小さい筒体を数量を増やすことが好ましい場合もある。従って、筒体の数や太さは適用する管路の太さ等の条件に応じて適宜設定することが好ましい。   The number and thickness of the cylinders constituting the heat exchange member are not particularly limited, and are preferably set as appropriate according to conditions such as the width of the heat exchange member and the thickness of the pipe. For example, when the diameter of the pipe line is small, the thickness of the cylinder is also reduced, and the number is increased. However, even when the thickness of the pipe line is large, it is not necessary to increase the thickness of the cylinder, and it may be preferable to increase the number of cylinders having a small thickness. Therefore, it is preferable to appropriately set the number and thickness of the cylinders according to conditions such as the thickness of the pipe line to be applied.

熱交換部材は、敷設される直前までロール状に巻き付けられており、管路に敷設される際には管路の内周面に沿って屈曲又は屈折する。このため、熱交換部材は充分な可撓性を有することが必要である。   The heat exchange member is wound in a roll shape until just before being laid, and is bent or refracted along the inner peripheral surface of the pipeline when laid on the pipeline. For this reason, the heat exchange member needs to have sufficient flexibility.

熱交換部材の一形態は、熱交換媒体が流通するための可撓性を有する筒体を太さ方向に複数本並べ、これらの筒体を可撓性を有する連結部材によって一体化させると共に、長さ方向の両端に開口させて構成されている。   As one form of the heat exchange member, a plurality of flexible cylinders for circulating the heat exchange medium are arranged in the thickness direction, and these cylinders are integrated by a flexible connecting member, Opened at both ends in the length direction.

熱交換部材を構成する筒体の太さや材質は特に限定するものではなく、充分な可撓性を有し、且つ熱交換部材が流通する際の内圧や管路を流れる水による外圧に対抗し得る強度を有するものであれば用いることが可能である。このような筒体の材質として、例えば、ポリエチレンに代表される合成樹脂チューブ、ステンレスやアルミニウム等の金属チューブをあげることが可能である。   The thickness and material of the cylinder constituting the heat exchange member are not particularly limited, and have sufficient flexibility, and resist the internal pressure when the heat exchange member circulates and the external pressure due to water flowing through the pipe line. Any material having the strength to obtain can be used. Examples of the material of such a cylindrical body include a synthetic resin tube represented by polyethylene and a metal tube such as stainless steel and aluminum.

特に、熱交換部材は、管路を流れる水と筒体を流れる熱交換媒体との熱交換を効率良く行うことが可能なように、熱伝導率の良好な材質によって構成されることが好ましい。このため、筒体や連結部材を薄い金属によって構成することが好ましい。しかし、熱交換部材を製造する際の、或いは管路に敷設する際の作業性からすると、合成樹脂によって構成することが好ましい。従って、熱交換部材を合成樹脂製とするか金属製とするかは、適用すべき管路の仕様や耐用年数等の諸条件を考慮して適宜設定することが好ましい。   In particular, the heat exchange member is preferably made of a material having good thermal conductivity so that heat exchange between the water flowing through the pipe and the heat exchange medium flowing through the cylinder can be performed efficiently. For this reason, it is preferable to comprise a cylinder and a connection member with a thin metal. However, from the viewpoint of workability at the time of manufacturing the heat exchange member or laying it in the pipe line, it is preferable to use a synthetic resin. Therefore, it is preferable to appropriately set whether the heat exchange member is made of synthetic resin or metal in consideration of various conditions such as the specification of the pipeline to be applied and the service life.

複数の筒体を一体化させる連結部材の構成は特に限定するものではなく、太さ方向に並べた複数の筒体を並列状態で一体化させることが可能で、且つこの状態を維持してロール状に巻き付けると共に、管路の内周面に沿って屈曲或いは屈折させることが可能であれば良い。このような連結部材は、筒体に対する一体化手段や材質に対応して選択することが必要となる。   The structure of the connecting member that integrates a plurality of cylinders is not particularly limited, and a plurality of cylinders arranged in the thickness direction can be integrated in a parallel state, and a roll is maintained while maintaining this state. It is only necessary to be able to be bent or refracted along the inner peripheral surface of the pipe line. Such a connecting member needs to be selected according to the means for integrating the cylindrical body and the material.

例えば、筒体として合成樹脂チューブを用いた場合、連結部材として合成樹脂製のシート或いは筒を利用することが可能である。連結部材としてシートを用いる場合には、並列した複数の筒体の横断方向の寸法(熱交換部材の幅寸法)より多少大きい幅寸法のシートを用意し、このシートを並列した筒体の一方側の面に配置して両者を接着或いは融着することで、一体化することが可能である。また、前記シートを2枚用意し、これらのシートを並列した筒体の両側の面に配置して両方のシートを筒体に接着或いは融着すると共に、両方のシートの幅方向の両端を互いに接着或いは融着することで、一体化することが可能である。   For example, when a synthetic resin tube is used as the cylinder, a synthetic resin sheet or cylinder can be used as the connecting member. When using a sheet as the connecting member, prepare a sheet with a width that is slightly larger than the dimension in the transverse direction of the multiple cylinders in parallel (the width dimension of the heat exchange member), and one side of the cylinder in which this sheet is aligned It is possible to integrate by adhering or fusing both together. In addition, two sheets are prepared, and these sheets are arranged on both sides of the parallel cylinder so that both sheets are bonded or fused to the cylinder, and both widthwise ends of both sheets are mutually attached. It can be integrated by bonding or fusing.

また、連結部材として、予め設定された幅寸法を有する長尺状のシートを用意し、このシートを並列させた筒体の外側に螺旋状に巻き付けることで一体化させることも可能である。この場合、予め筒体又はシートに接着剤を塗布しておくことで、或いはシートを螺旋状に巻き付けた後融着することで、一体化することが可能である。   Moreover, it is also possible to prepare a long sheet having a preset width dimension as the connecting member, and to integrate the sheet by spirally winding the sheet around the parallel cylinder. In this case, it is possible to integrate by applying an adhesive to the cylinder or the sheet in advance, or by winding the sheet spirally and then fusing.

連結部材として合成樹脂製の筒を用いた場合には、並列した複数の筒体を筒に挿入する段階で接着剤を塗布して接着し、或いは挿入した後融着することで、一体化することが可能である。また、連結手段として熱収縮性樹脂からなる筒を用いた場合には、複数の筒体を挿入した後、全体を加熱して該筒を収縮させることで、一体化することが可能である。   When a synthetic resin cylinder is used as the connecting member, an adhesive is applied and bonded at the stage where a plurality of parallel cylinders are inserted into the cylinder, or they are fused together to be integrated. It is possible. Further, when a cylinder made of heat-shrinkable resin is used as the connecting means, it is possible to integrate by inserting a plurality of cylinders and then contracting the cylinder by heating the whole.

また、筒体として、可撓性を有する銅やステンレス或いはアルミニウム等を含む金属製のチューブ、ジャバラ管、螺旋管等の管(金属チューブ)を用いる場合、連結部材として金属製のシート或いは熱収縮性の合成樹脂からなる筒を用いることが可能である。連結部材としてシートを用いた場合、前述した合成樹脂製の筒体に対するのと同様に、1枚又は2枚のシートを用意し、このシートを並列した筒体の一方側の面、或いは両側の面に配置し、並列した筒体とシートを接着或いは溶接等の手段で、一体化することが可能である。   In addition, when a tube made of metal (such as flexible copper, stainless steel, or aluminum), a bellows tube, a spiral tube or the like (metal tube) is used as the cylinder, a metal sheet or heat shrinkage is used as the connecting member. It is possible to use a tube made of a synthetic resin. When a sheet is used as the connecting member, one or two sheets are prepared in the same manner as for the synthetic resin cylinder described above, and one side surface of the cylinder body in which the sheets are arranged side by side or both sides It is possible to integrate the cylinders and sheets arranged on the surface and arranged in parallel by means such as adhesion or welding.

また、連結部材として合成樹脂製の筒を用いた場合、前述した合成樹脂製の筒体に対するのと同様に、並列した複数の筒体を筒に挿入する段階で接着剤を塗布して接着し、或いは挿入した後融着することで、一体化することが可能である。また、熱収縮性の筒に並列した複数の筒体を挿入した後、全体を加熱することによって該筒を収縮させることで、一体化することが可能である。   In addition, when a synthetic resin cylinder is used as the connecting member, an adhesive is applied and bonded at the stage where a plurality of parallel cylinders are inserted into the cylinder, as in the case of the synthetic resin cylinder described above. Alternatively, it can be integrated by inserting and then fusing. In addition, after inserting a plurality of cylinders arranged in parallel with the heat-shrinkable cylinder, it is possible to integrate the cylinder by contracting it by heating the whole.

連結部材として、並列した複数の筒体の横断方向の寸法より多少大きい幅寸法のシートを用いる場合、このシートの一方側の面に筒体の外形に対応する位置に突起を設けておくことが好ましい。このような突起を設けることによって、並列した複数の筒体の一方側の面或いは両側の面に配置したとき、筒体の並列状態を容易に保持することが可能であり、且つ接着剤の塗布面を確保することが可能である。   When a sheet having a width that is slightly larger than the transverse dimension of a plurality of cylinders arranged in parallel is used as the connecting member, a protrusion may be provided on the surface on one side of the sheet at a position corresponding to the outer shape of the cylinder. preferable. By providing such protrusions, it is possible to easily maintain the parallel state of the cylinders and to apply the adhesive when they are arranged on one or both surfaces of a plurality of parallel cylinders. It is possible to secure the surface.

上記の如く、連結部材としては、合成樹脂或いは薄い金属によって形成された、熱交換部材の幅寸法に対応させた幅寸法を持つシートや、熱交換部材の幅寸法に関わらず設定された幅寸法を持つシート、或いは筒等の形状を有するものを採用することが可能である。   As described above, as a connecting member, a sheet having a width dimension corresponding to the width dimension of the heat exchange member formed of synthetic resin or a thin metal, or a width dimension set regardless of the width dimension of the heat exchange member It is possible to adopt a sheet having a shape or a shape such as a cylinder.

しかし、管路を流れる水との熱交換を効率良く行うためには、熱交換部材に於ける少なくとも管路を流れる水と対向する面に可撓性を有する金属を配することが好ましい。可撓性を有する金属としては、ステンレス或いはアルミニウムのシートを用いることが可能である。そして、このような金属を連結部材として用いることで、熱交換効率の高い熱交換部材を実現することが可能となる。   However, in order to efficiently exchange heat with water flowing through the pipe, it is preferable to dispose a flexible metal on at least the surface of the heat exchange member that faces the water flowing through the pipe. As the flexible metal, a stainless or aluminum sheet can be used. And it becomes possible by using such a metal as a connection member to implement | achieve a heat exchange member with high heat exchange efficiency.

熱交換部材の長さ方向の両端に於ける筒体の開口には、ヒートポンプに接続される配管や、隣接する筒体どうしを接続する配管が接続される。   Pipes connected to the heat pump and pipes connecting adjacent cylinders are connected to the openings of the cylinders at both ends in the length direction of the heat exchange member.

本発明に於いて、熱交換部材の構成は上記構成にのみ限定するものではなく、可撓性を有する長尺状の本体部材の内部に熱交換媒体が流通する複数の流通路を長手方向に貫通すると共に太さ方向に隣接して形成し、長手方向の両端に流通路を開口させたものであっても良い。   In the present invention, the configuration of the heat exchange member is not limited to the above configuration, and a plurality of flow passages through which the heat exchange medium circulates inside the flexible main body member are arranged in the longitudinal direction. It may be formed so as to penetrate and be adjacent to the thickness direction and have flow paths opened at both ends in the longitudinal direction.

上記構成に於いて、熱交換部材は、合成樹脂の押出成型によって形成されており、本体部材の成形と同時に流通路も成形される。熱交換部材の材質は、ポリエチレンや塩化ビニル等を採用することが可能である。塩化ビニルは、常温では充分な可撓性を発揮し得ないことがあるが、保管時にロール状に巻き付ける際に、敷設施工時にロールを巻き戻す際に加熱することで可撓性を発揮させることが可能である。   In the above configuration, the heat exchange member is formed by extrusion molding of a synthetic resin, and the flow path is also formed simultaneously with the formation of the main body member. As the material of the heat exchange member, polyethylene, vinyl chloride, or the like can be used. Vinyl chloride may not be able to exhibit sufficient flexibility at room temperature, but when it is wound into a roll during storage, it should be made flexible by heating when it is rewound during installation. Is possible.

熱交換部材の実施例について図1を用いて説明する。図1に示す熱交換部材Aは、複数の筒体1を太さ方向に並べた状態で連結部材2によって一体化させて構成されている。   An embodiment of the heat exchange member will be described with reference to FIG. The heat exchange member A shown in FIG. 1 is configured by integrating a plurality of cylindrical bodies 1 with a connecting member 2 in a state in which they are arranged in the thickness direction.

筒体1としては、可撓性を有する太さが約10mm〜約20mmのポリエチレンチューブを用いており、10本の筒体1を並列させて一体化している。しかし、筒体1の数はこの本数に限定するものではなく、10本以上であっても、或いは10本以下であっても、熱交換部材Aとすることは可能である。   As the cylinder 1, a flexible polyethylene tube having a thickness of about 10 mm to about 20 mm is used, and the 10 cylinders 1 are integrated in parallel. However, the number of the cylinders 1 is not limited to this number, and the heat exchange member A can be used even if the number is 10 or more or 10 or less.

連結部材2としては、可撓性を有する熱収縮性の合成樹脂(シュリンク包装に用いるシュリンクフィルム)によって形成された筒を用いている。この連結部材2に、複数並べた筒体1を挿通すると共に両端部分を夫々突出させ、その後、連結部材2を加熱して収縮させることで、複数の筒体1を連結部材2によって一体化することが可能である。   As the connecting member 2, a tube formed of a heat-shrinkable synthetic resin having flexibility (a shrink film used for shrink packaging) is used. A plurality of cylinders 1 arranged in the connecting member 2 are inserted and both end portions are protruded, and then the connecting member 2 is heated and contracted to integrate the plurality of cylinders 1 with the connecting member 2. It is possible.

このようにして構成された熱交換部材Aは、予め設定された幅寸法と長さとを有し、長さ方向の両端に夫々筒体1が自由に開口すると共に、幅方向の両端が筒体1の外形に略等しい形状を有する扁平な帯状の部材として構成されている。また、前記の如く構成された熱交換部材Aは、長さ方向及び幅方向に夫々充分な可撓性を有している。   The heat exchange member A configured in this way has a preset width dimension and length, and the cylindrical body 1 freely opens at both ends in the length direction, and both ends in the width direction are cylindrical bodies. It is comprised as a flat strip-shaped member which has a shape substantially equal to 1 external shape. The heat exchange member A configured as described above has sufficient flexibility in the length direction and the width direction.

次に、熱交換部材Aの他の例について図2により説明する。   Next, another example of the heat exchange member A will be described with reference to FIG.

図2(a)に示す熱交換部材Aは、並列した複数の筒体1の一方側の面に1枚のステンレス製のシート状の連結部材2を配置し、各筒体1と連結部材2とを接着、融着又は溶接等の手段によって一体化させたものである。このように構成された熱交換部材Aは、構造が簡単でコスト面で有利である。特に、管路に配置するに際し、連結部材2を管路の内周面側に配置しても、流れる水側に配置しても良く、使い勝手の良い熱交換部材Aとすることが可能である。   In the heat exchange member A shown in FIG. 2A, a single sheet-like connecting member 2 made of stainless steel is arranged on one surface of a plurality of juxtaposed cylinders 1, and each cylindrical body 1 and the connecting member 2 are arranged. Are integrated by means such as adhesion, fusion or welding. The heat exchange member A configured in this manner is simple in structure and advantageous in terms of cost. In particular, when arranged in the pipeline, the connecting member 2 may be arranged on the inner peripheral surface side of the pipeline or on the flowing water side, and the heat exchange member A that is easy to use can be obtained. .

同図(b)に示す熱交換部材Aは、筒体1として断面が角型の合成樹脂チューブ或いは金属チューブであって、夫々の断面形状が異なるように形成されたものを用いている。そして、高さ方向の寸法が大きい筒体1を中央に配置し、この筒体1の両側に順に高さ方向の寸法が小さい筒体1を並べ、並列した複数の筒体1を合成樹脂製或いは金属製の筒状の連結部材2に挿入して一体化させることで熱交換部材Aが構成されている。特に、連結部材2の幅方向の両端側には突起部4が形成されている。   A heat exchanging member A shown in FIG. 2B uses a cylindrical synthetic resin tube or metal tube having a square cross section as the cylindrical body 1 and having a different cross sectional shape. And the cylinder 1 with a large dimension of a height direction is arrange | positioned in the center, the cylinder 1 with a small dimension of a height direction is arranged in order on both sides of this cylinder 1, and the several cylinder 1 paralleled is made from a synthetic resin. Or the heat exchange member A is comprised by inserting in the metal cylindrical connection member 2, and making it integrate. In particular, protrusions 4 are formed on both ends of the connecting member 2 in the width direction.

同図(c)に示す熱交換部材Aは、並列させた複数の筒体1を合成樹脂製或いは金属製の筒状の連結部材2によって一体化し、隣接する筒体1の間に形成された間隙を充填材3によって充填したものである。   The heat exchange member A shown in FIG. 2C is formed between adjacent cylinders 1 by integrating a plurality of juxtaposed cylinders 1 by a synthetic resin or metal cylindrical connecting member 2. The gap is filled with the filler 3.

充填材3としては、少なくとも初期状態に於ける熱交換部材Aの可撓性を阻害するものであってはならず、且つ良好な熱伝導性を有するものであることが好ましい。このような充填材3としては、アルミニウム粉末や鉄粉末を含む金属粉末、合成樹脂製の粒等があり、これらの中から適宜選択して充填することが好ましい。   The filler 3 should not inhibit the flexibility of the heat exchange member A at least in the initial state, and preferably has good thermal conductivity. Examples of such a filler 3 include metal powder including aluminum powder and iron powder, and particles made of synthetic resin, and it is preferable to select and fill them appropriately.

上記の如く、隣接する筒体1の間に形成された間隙を充填材3によって閉塞した熱交換部材Aでは、前記間隙に空気が存在する場合に比べて熱伝導性の向上をはかることが可能となり、筒体1に流通する熱交換媒体と水との間で良好な熱交換を実現することが可能である。   As described above, in the heat exchange member A in which the gap formed between the adjacent cylindrical bodies 1 is closed by the filler 3, it is possible to improve the thermal conductivity as compared with the case where air exists in the gap. Thus, it is possible to realize good heat exchange between the heat exchange medium flowing in the cylinder 1 and the water.

このように構成された熱交換部材Aでは、中央から両端側に向けて厚さが小さくなっており、適用する管路が円筒状の管によって構成されるような場合に有利である。特に、連結部材2が筒状の合成樹脂からなり、適用する管路が硬化した合成樹脂管によって構成されている場合、連結部材2の幅方向の両端に形成された突起4を利用して合成樹脂管に接着又は融着或いは溶接することが可能となる。   The heat exchange member A configured in this way has a thickness that decreases from the center toward both ends, which is advantageous when the applied pipe is constituted by a cylindrical tube. In particular, when the connecting member 2 is made of a cylindrical synthetic resin and the applied pipe is made of a hardened synthetic resin tube, the connecting member 2 is synthesized using the protrusions 4 formed at both ends in the width direction. It becomes possible to adhere or fuse or weld the resin tube.

次に、熱交換部材の更に他の例について図3により説明する。   Next, still another example of the heat exchange member will be described with reference to FIG.

図3(a)に示す熱交換部材Bは、可撓性を有する長尺状の本体部材5の内部に、熱交換媒体が流通する複数の流通路6が長手方向に貫通すると共に該流通路の太さ方向に隣接して形成され、長手方向の両端に開口して構成されている。   A heat exchange member B shown in FIG. 3 (a) has a plurality of flow passages 6 through which a heat exchange medium circulates in the longitudinal direction inside a long body member 5 having flexibility. Are formed adjacent to each other in the thickness direction and open at both ends in the longitudinal direction.

本体部材5は熱可塑性樹脂からなり、該本体部材5を押出成型するのと同時に流通路6を成形するか、或いは予め熱可塑性樹脂からなる複数のチューブを並列させた状態で成形して一体化させている。このため、熱交換部材Bは如何なる断面形状にも成形することが可能であり、適用すべき管路の断面形状、及び該管路に対する敷設条件に最適な形状に形成されている。   The main body member 5 is made of a thermoplastic resin, and at the same time as the main body member 5 is extruded, the flow passage 6 is formed, or a plurality of tubes made of thermoplastic resin are previously formed in parallel and integrated. I am letting. For this reason, the heat exchange member B can be formed in any cross-sectional shape, and is formed in a shape optimal for the cross-sectional shape of the pipe line to be applied and the laying conditions for the pipe line.

同図(b)に示す熱交換部材Bは、本体部材5に於ける一方の面側(熱交換部材Bを管路に敷設したときに流れる水と対向する面側)に複数の溝を並べて形成し、これらの溝の開口部分を金属製の薄いシート状の蓋部材7によって閉塞することで流通路6を構成したものである。   The heat exchanging member B shown in FIG. 4B has a plurality of grooves arranged on one side of the main body member 5 (the side facing the water that flows when the heat exchanging member B is laid on the pipe). The flow path 6 is formed by forming and closing the opening portions of these grooves with a thin sheet-like lid member 7 made of metal.

上記の如く構成された熱交換部材Bでは、本体部材5が熱可塑性樹脂によって構成されるため、敷設すべき管路が鉄筋コンクリート管であっても、硬化した合成樹脂管であっても良好に対応することが可能である。特に、同図(b)に示す熱交換部材Bでは、硬化した合成樹脂管の内周面に敷設する際に、容易に且つ確実に該合成樹脂管と接着、融着或いは溶接することが可能であり、且つ流通路6が薄い蓋部材7を介して流れる水との熱交換を行うことが可能となる。   In the heat exchanging member B configured as described above, since the main body member 5 is made of thermoplastic resin, the pipe line to be laid can be a reinforced concrete pipe or a hardened synthetic resin pipe. Is possible. In particular, in the heat exchange member B shown in FIG. 4B, when laying on the inner peripheral surface of the cured synthetic resin tube, it can be easily and reliably bonded, fused or welded to the synthetic resin tube. In addition, it is possible to exchange heat with water flowing through the lid member 7 in which the flow passage 6 is thin.

次に、本発明に係る熱交換部材を管路に敷設する際の第1の施工方法について説明する。   Next, the 1st construction method at the time of laying the heat exchange member concerning the present invention in a pipe line is explained.

本発明に係る第1の施工方法は、前述した図1〜図3に示す熱交換部材A、Bの何れかを、水が流れる管路の長手方向であって該管路の内周面に沿って配置し、その後、可撓性を有するスリーブを縮径した状態で管路の内部に挿入し、該スリーブを復元させて復元したスリーブと管路を構成する既設管との間に挟み込むようにしたものである。   In the first construction method according to the present invention, any one of the heat exchange members A and B shown in FIGS. 1 to 3 described above is arranged on the inner peripheral surface of the pipe in the longitudinal direction of the pipe through which water flows. The flexible sleeve is then inserted into the conduit with the diameter reduced, and the sleeve is restored, and the restored sleeve is sandwiched between the restored sleeve and the existing pipe constituting the conduit. It is a thing.

前述したように、水が流れる管路として、下水道用の管路、上水道用の管路、農業用水用の管路、工業用水用の管路を含む種々の水流用の管路があり、何れにも適用することが可能である。また、管路を構成する既設管の形状は円筒形、角筒形等の形状があり、何れの形状であっても適用することが可能である。   As described above, there are various water flow pipes including water pipes, sewer pipes, agricultural water pipes, industrial water pipes, and the like. It is also possible to apply to. Moreover, the shape of the existing pipe which comprises a pipe line has shapes, such as a cylindrical shape and a rectangular tube shape, and it can apply even if it is any shape.

可撓性を有するスリーブとして、断面形状を限定するものではなく、配置すべき管路を構成する既設管の内形と対応し、且つ既設管との間に熱交換部材A、Bを挟み込むことが可能な外形を有する外周面を有する。スリーブの外周面の外形が既設管の内形と対応するとは、スリーブの外形は既設管の内形と略相似形であることを意味している。即ち、既設管の内形が円形である場合、スリーブの外形は適用される熱交換部材A、Bを考慮した略円形となり、断面形状は略円筒形となる。また、既設管の内形が角型である場合、スリーブの外径も略角型となり、断面形状は略角筒形となる。   As a flexible sleeve, the cross-sectional shape is not limited, and it corresponds to the inner shape of the existing pipe constituting the pipe line to be arranged, and the heat exchange members A and B are sandwiched between the existing pipes. It has the outer peripheral surface which has the external shape which can be. The fact that the outer shape of the outer peripheral surface of the sleeve corresponds to the inner shape of the existing pipe means that the outer shape of the sleeve is substantially similar to the inner shape of the existing pipe. That is, when the inner shape of the existing pipe is circular, the outer shape of the sleeve is substantially circular considering the applied heat exchange members A and B, and the cross-sectional shape is substantially cylindrical. Further, when the inner shape of the existing pipe is a square shape, the outer diameter of the sleeve is also a substantially square shape, and the cross-sectional shape is a substantially rectangular tube shape.

スリーブの外形寸法は特に限定するものではなく、既設管の内部に容易に且つ確実に挿入することが可能で、且つ既設管との間に熱交換部材を確実に挟入ことが可能な寸法であれば良い。また、スリーブの長さも限定するものではなく、配置される管路の長さの自由度を高めるために長尺状であることが好ましい。そして、長尺状のスリーブを縮径して例えばドラムやリールに巻き付けて、或いは長手方向に折り畳んで籠状のケースに収容して、保管、又は搬送し得るように構成することが好ましい。   The outer dimension of the sleeve is not particularly limited, and can be easily and reliably inserted into the existing pipe, and can be securely inserted between the existing pipe and the heat exchange member. I just need it. Further, the length of the sleeve is not limited, and the sleeve is preferably long in order to increase the degree of freedom of the length of the pipe line to be arranged. It is preferable that the long sleeve is reduced in diameter and wound around, for example, a drum or a reel, or folded in the longitudinal direction and accommodated in a bowl-like case for storage or transportation.

スリーブを縮径する場合、スリーブの断面が小さくなるように畳む場合と、スリーブの温度を降下させて縮ませる場合と、がある。更に、後述するようにスリーブが含浸基材に熱可塑性樹脂を含浸させて構成されたものでは、硬化させる際の膨張を見込んで、予め含浸基材の径を既設管の内径よりも小さく形成することで縮径したものもある。   When reducing the diameter of the sleeve, there are a case where the sleeve is folded so that the cross section of the sleeve is small, and a case where the sleeve is contracted by lowering the temperature of the sleeve. Further, in the case where the sleeve is configured by impregnating the impregnated base material with a thermoplastic resin as will be described later, the diameter of the impregnated base material is previously formed smaller than the inner diameter of the existing pipe in anticipation of expansion when cured. Some of them have a reduced diameter.

スリーブを断面内で畳んで縮径する場合、単にスリーブの断面が扁平になるように畳む方法と、周の一部を対向する周に接触するようにΩ状に凹ませて畳む方法と、があり、何れの畳み方であっても、ドラムやリールに巻き付けることが可能であり好ましい。   When the sleeve is folded in the cross section to reduce the diameter, there are a method of simply folding the sleeve so that the cross section of the sleeve becomes flat, and a method of folding the sleeve so that a part of the circumference is in contact with the opposite circumference and folds into a Ω shape. Yes, any way of folding is preferable because it can be wound around a drum or a reel.

スリーブは合成樹脂によって成形されている。スリーブを成形する合成樹脂として、塩化ビニルやポリエチレン或いはポリエチレンテレフタレートに代表される熱可塑性樹脂を利用することが可能である。熱可塑性樹脂によってスリーブを製造する場合、常温状態に於ける成形体が高い剛性を有するため、流通路を形成する際には多様な方法を採用することが可能である。   The sleeve is formed of a synthetic resin. As a synthetic resin for forming the sleeve, a thermoplastic resin typified by vinyl chloride, polyethylene, or polyethylene terephthalate can be used. When a sleeve is manufactured from a thermoplastic resin, various methods can be employed when forming the flow path because the molded body at room temperature has high rigidity.

熱可塑性樹脂によって製造されたスリーブは、加熱することによって容易に変形することが可能であり、常温では充分に高い剛性を有する。このため、目的の管路に配置する際の施工性が良い。特に、既設管の内部に配置した後、経年による劣化や他の原因により補修する必要が生じたとき、内部に加熱蒸気や温水を供給して加温することでスリーブを軟化させて容易に抜き出すことが可能である。   A sleeve made of a thermoplastic resin can be easily deformed by heating, and has a sufficiently high rigidity at room temperature. For this reason, the workability at the time of arrange | positioning to the target pipe line is good. In particular, when it is necessary to repair after deterioration due to aging or other causes after being placed inside an existing pipe, the sleeve is softened by heating by supplying heated steam or hot water to the inside and easily pulled out. It is possible.

また、スリーブを成形する合成樹脂として、不飽和ポリエステル樹脂からなる熱硬化性樹脂や不飽和ポリエステル樹脂に光開始剤を含有させた光硬化性樹脂(以下、熱硬化性樹脂と光硬化性樹脂を含んで「熱硬化性樹脂」という)を利用することが可能である。熱硬化性樹脂を利用する場合、含浸基材となる筒状の不織布や強化繊維に熱硬化性樹脂を含浸させた可撓性を有するスリーブを用いることが必要となる。   In addition, as a synthetic resin for forming a sleeve, a thermosetting resin made of an unsaturated polyester resin or a photocurable resin in which an unsaturated polyester resin contains a photoinitiator (hereinafter referred to as a thermosetting resin and a photocurable resin). Including "thermosetting resin"). When a thermosetting resin is used, it is necessary to use a cylindrical non-woven fabric that becomes an impregnated base material or a flexible sleeve in which a reinforcing fiber is impregnated with a thermosetting resin.

本発明に於けるスリーブは、単に管路に配置された熱交換部材A、Bを、該管路を構成する既設管とで挟んで敷設する機能を有するものであれば良い。しかし、既設管の内周面が老朽化しているような場合には、該既設管の内周面を補修するためのライニング材としての機能を併せ持つことが好ましい。   The sleeve in the present invention only needs to have a function of laying the heat exchanging members A and B arranged in the pipe line between existing pipes constituting the pipe line. However, when the inner peripheral surface of the existing pipe is aged, it is preferable to have a function as a lining material for repairing the inner peripheral surface of the existing pipe.

前述した、熱可塑性樹脂からなるスリーブ、含浸基材に熱硬化性樹脂を含浸させたスリーブ、或いは含浸基材に光硬化性樹脂を含浸させたスリーブ、は何れも管路を補修する際に補修用のライニング材としての機能を有するものである。   The above-described sleeve made of thermoplastic resin, sleeve in which the impregnated base material is impregnated with thermosetting resin, or sleeve in which the impregnated base material is impregnated with photocurable resin are all repaired when repairing the pipeline. It has a function as a lining material.

次に、上記第1の施工方法の実施例について図4〜図8により説明する。尚、水が流れる管路に敷設する熱交換部材は、図1に示すものが採用されている。   Next, examples of the first construction method will be described with reference to FIGS. In addition, the thing shown in FIG. 1 is employ | adopted as the heat exchange member laid in the pipe line through which water flows.

本実施例に於いて、水が流れる管路は下水道用の管路Cとして構成されており、図6に示すように、隣接するマンホール11、12の間に構成されている。下水道用の管路Cは、隣接するマンホール11、12の間を複数の鉄筋コンクリート管(既設管C、以下、管路C又は既設管Cということがある)を直列に接続することで構成されいる。   In this embodiment, the pipe through which water flows is configured as a sewer pipe C, and is formed between adjacent manholes 11 and 12 as shown in FIG. The sewer pipe C is formed by connecting a plurality of reinforced concrete pipes (existing pipes C, hereinafter referred to as pipes C or existing pipes C) in series between adjacent manholes 11 and 12. .

マンホール11、12は、直壁管と斜壁管を縦方向に接続して構成されており、底部には既設管Cと同じレベルの溝を形成した底盤13が設けられている。また、各マンホール11、12の底盤13に於ける管路Cが開口する部位には、該管路Cを構成する既設管Cの肉厚方向に窪み13aが形成されている。   The manholes 11 and 12 are configured by connecting a straight wall pipe and a slant wall pipe in the vertical direction, and a bottom plate 13 having a groove at the same level as the existing pipe C is provided at the bottom. In addition, a recess 13 a is formed in the thickness direction of the existing pipe C constituting the pipe C at a portion where the pipe C is opened in the bottom plate 13 of each manhole 11, 12.

熱交換部材Aは、予めロール状に巻き付けられた状態でトラック等の搬送手段によって一方のマンホール11まで搬送される。そして、巻き付けたロールから熱交換部材Aを巻き戻しながらマンホール11から管路Cの内部に挿入し、マンホール12まで移送する。このとき、熱交換部材Aを如何なる方法で管路Cの内部に挿通するかは限定するものではなく、予めマンホール11、12間の管路Cにワイヤロープを挿通しておき、このワイヤロープを利用して熱交換部材Aを挿入することが可能である。   The heat exchange member A is transported to one manhole 11 by a transporting means such as a truck in a state of being wound in advance in a roll shape. Then, while rewinding the heat exchange member A from the wound roll, the heat exchange member A is inserted into the pipe C from the manhole 11 and transferred to the manhole 12. At this time, it is not limited how the heat exchange member A is inserted into the pipe C, and a wire rope is inserted in the pipe C between the manholes 11 and 12 in advance. It is possible to insert the heat exchange member A by using it.

マンホール11、12の間に熱交換部材Aを挿入した後、挿入された熱交換部材Aを管路Cの底面側に、且つ該熱交換部材Aの中央部分が管路Cの最低部分と対応するように配置すると共に、熱交換部材Aを管路Cの内周面に沿わせて正確に配置する。これにより、熱交換部材Aは、管路Cの内周面に沿って且つ長手方向に設置される。   After the heat exchange member A is inserted between the manholes 11 and 12, the inserted heat exchange member A corresponds to the bottom surface side of the pipe line C, and the central portion of the heat exchange member A corresponds to the lowest part of the pipe line C. The heat exchange member A is accurately arranged along the inner peripheral surface of the pipe C. Thereby, the heat exchange member A is installed along the inner peripheral surface of the pipe C and in the longitudinal direction.

マンホール11、12間の管路Cに熱交換部材Aを設置した後、該熱交換部材Aの連結部材2を各マンホール11、12に合わせて切断すると共に、筒体1を連結部材2の切断部位よりも突出させた状態で切断しておく。そして、各筒体1に水等の非圧縮性流体を充填して端部を閉鎖する。これにより、熱交換部材Aに外部から力が作用しても、部分的な変形を防ぐことが可能となる。   After the heat exchange member A is installed in the pipe C between the manholes 11 and 12, the connecting member 2 of the heat exchange member A is cut in accordance with the manholes 11 and 12, and the cylindrical body 1 is cut off of the connecting member 2. Cut in a state protruding from the site. And each cylinder 1 is filled with incompressible fluids, such as water, and an edge part is closed. Thereby, even if a force acts on the heat exchange member A from the outside, partial deformation can be prevented.

予め凹状(Ω状)に畳まれて縮径されて硬化したスリーブDを、ドラムに巻き付けた状態でトラック等の搬送手段により管路の端部となる一方のマンホール11まで搬送し、ドラムをマンホール11の近傍に設置する。その後、スリーブDを加熱して軟化させつつ、ドラムを巻戻方向に回転させて軟化したスリーブDを繰り出し、この繰り出しによりスリーブDをマンホール11から管路Cの内部に挿入する。   The sleeve D, which has been previously collapsed into a concave shape (Ω shape) and reduced in diameter and cured, is conveyed to one manhole 11 serving as an end of a pipe line by a conveying means such as a track while being wound around the drum. 11 is installed in the vicinity. Thereafter, while the sleeve D is heated and softened, the drum is rotated in the unwinding direction to feed out the softened sleeve D, and the sleeve D is inserted into the pipe C from the manhole 11 by this feeding.

図4に示すように、スリーブDを管路Cに挿入する際に、該スリーブDが凹んだ状態に畳まれた状態であることから、スリーブDを管路Cに干渉させることなく円滑に挿入することが可能である。そして。スリーブDをマンホール11、12の間の管路Cに挿入した後、該スリーブDを例えばマンホール11、12に於ける略中央部位で切断する。   As shown in FIG. 4, when the sleeve D is inserted into the conduit C, since the sleeve D is in a folded state, the sleeve D can be smoothly inserted without interfering with the conduit C. Is possible. And then. After the sleeve D is inserted into the conduit C between the manholes 11 and 12, the sleeve D is cut at, for example, a substantially central portion in the manholes 11 and 12.

次いで、凹状に畳まれた状態を保持しているスリーブDを温水や蒸気或いは加熱空気により加熱して更に柔軟性を発揮させる。即ち、スリーブDの内部、又はスリーブDの内部及び管路Cの内部(スリーブDの外周面側)に温水や蒸気或いは加熱空気を供給して加熱して、スリーブDの可撓性を復帰させる。   Next, the sleeve D holding the recessed state is heated with warm water, steam or heated air to further exhibit flexibility. That is, warm water, steam, or heated air is supplied to the inside of the sleeve D or the inside of the sleeve D and the inside of the pipe C (on the outer peripheral surface side of the sleeve D) and heated to restore the flexibility of the sleeve D. .

スリーブDが充分に可撓性を復帰したとき、作業員により、或いはスリーブDの内部に供給した蒸気により、断面形状を凹状から円弧状に復元させ、外周面を管路Cの内周面に密着させる。スリーブDが管路Cの内周面に密着するのに伴って、熱交換部材Aは両者の間に挟まれる。   When the sleeve D sufficiently returns to flexibility, the cross-sectional shape is restored from the concave shape to the arc shape by the worker or by the steam supplied to the inside of the sleeve D, and the outer peripheral surface becomes the inner peripheral surface of the pipe C. Adhere closely. As the sleeve D comes into close contact with the inner peripheral surface of the pipe C, the heat exchange member A is sandwiched between them.

その後、温水や蒸気或いは加熱空気の供給を停止し、常温の水或いは常温の空気等の気体を供給して冷却する。スリーブDは強制的に冷却されて硬化し、密着した形状を保持する。このため、硬化したスリーブDと管路Cの内周面との間に挟まれた熱交換部材Aは、安定した状態を維持して両者の間に敷設される。   Thereafter, the supply of hot water, steam, or heated air is stopped, and a gas such as room temperature water or room temperature air is supplied to cool. The sleeve D is forcibly cooled and hardened, and maintains a tightly adhered shape. For this reason, the heat exchange member A sandwiched between the hardened sleeve D and the inner peripheral surface of the pipe C is laid between the two while maintaining a stable state.

そして、充分にスリーブDが硬化した後、該スリーブDの各マンホール11、12に突出している部分を、マンホール11、12の壁面と同一面となるように切削する。   Then, after the sleeve D is sufficiently cured, the portions of the sleeve D protruding into the manholes 11 and 12 are cut so as to be flush with the wall surfaces of the manholes 11 and 12.

その後、図7、図8に示すように、熱交換部材Aの端面に開口している複数の筒体1を選択して一方の筒体1に熱交換媒体の供給部材となる供給管15を接続すると共に、他方の筒体1に熱交換媒体の受給部材となる受給管16を接続する。また、残った筒体1の開口には夫々U字管17を接続して連通する。   Thereafter, as shown in FIGS. 7 and 8, a plurality of cylinders 1 opened on the end face of the heat exchange member A are selected, and a supply pipe 15 serving as a heat exchange medium supply member is provided in one cylinder 1. While being connected, a receiving pipe 16 serving as a heat exchange medium receiving member is connected to the other cylindrical body 1. In addition, U-tubes 17 are connected to and communicated with the remaining openings of the cylinder 1.

熱交換部材Aの筒体1から選択された筒体1に供給管15、受給管16を接続する際に、これらの供給管15と受給管16を同じマンホール11に設けるか、マンホール11、12に夫々設けるかは限定するものではなく、地上に設置したヒートポンプ18の使い方や、管路Cの長さ等の条件に応じて設定される。   When connecting the supply pipe 15 and the receiving pipe 16 to the cylindrical body 1 selected from the cylindrical body 1 of the heat exchange member A, the supply pipe 15 and the receiving pipe 16 are provided in the same manhole 11, or the manholes 11, 12 It is not limited whether each is provided, and it is set according to conditions such as how to use the heat pump 18 installed on the ground and the length of the pipe C.

例えば、図6に示すように、一方のマンホール11に供給管15、受給管16を設けてヒートポンプ18に接続する場合、マンホール11に開口している熱交換部材Aを構成する筒体1から両端側の二つの筒体1を選択して夫々供給管15、受給管16を接続すると共に、残った筒体1にU字管17を接続して連通させ、マンホール12に開口して隣接している筒体1を夫々U字管17を接続して連通させて、複数の筒体1を連続させた熱交換媒体を流通させる一連の流通路として構成することが可能である。また、一方のマンホールに供給管15を、他方のマンホールに受給管16を設けた場合でも、同様にして筒体1を選択することで、流通路を構成することが可能である。   For example, as shown in FIG. 6, when a supply pipe 15 and a receiving pipe 16 are provided in one manhole 11 and connected to the heat pump 18, both ends from the cylindrical body 1 constituting the heat exchange member A opened in the manhole 11 are provided. The two cylinders 1 on the side are selected and the supply pipe 15 and the receiving pipe 16 are connected to each other, and a U-shaped pipe 17 is connected to and communicated with the remaining cylinder 1 so as to open and be adjacent to the manhole 12. It is possible to configure the cylindrical body 1 as a series of flow passages through which a heat exchange medium including a plurality of cylindrical bodies 1 is circulated by connecting the U-shaped pipes 17 to each other. Even when the supply pipe 15 is provided in one manhole and the receiving pipe 16 is provided in the other manhole, the flow passage can be configured by selecting the cylinder 1 in the same manner.

上記の如くしてマンホール11、12に開口している筒体1に夫々供給管15、受給管16、U字管17を接続したとき、これらの管15〜17と筒体1の接続部分は底盤13に形成された窪み13a内に存在する。また、スリーブDの内周面のレベルは初期の底盤13の流水レベルよりも上位となる。このため、モルタル20によって窪み13aを埋めると共に底盤13の流水レベルを上昇させる。   As described above, when the supply pipe 15, the receiving pipe 16, and the U-shaped pipe 17 are connected to the cylinder 1 that is open to the manholes 11 and 12, respectively, the connecting portion between these pipes 15 to 17 and the cylinder 1 is as follows. It exists in a recess 13 a formed in the bottom plate 13. Further, the level of the inner peripheral surface of the sleeve D is higher than the initial flowing water level of the bottom base 13. For this reason, the recess 13a is filled with the mortar 20 and the running water level of the bottom board 13 is raised.

供給管15、受給管16は地上に設置したヒートポンプ18に接続されている。また、ヒートポンプ18には図示しない冷暖房器具などが接続され、これにより、管路を流れる水の熱を活用することが可能である。   The supply pipe 15 and the receiving pipe 16 are connected to a heat pump 18 installed on the ground. The heat pump 18 is connected to a heating / cooling appliance (not shown) and the like so that the heat of water flowing through the pipe can be utilized.

尚、スリーブDが光硬化性樹脂或いは熱硬化性樹脂によって構成されている場合、このスリーブAは可撓性を有する状態で現場まで搬送され、目的の管路に反転法或いは引込法によって挿入される。その後、スリーブDの内部に圧縮空気を供給して膨張させることで、管路Cの内面に密着させる。スリーブDが管路Cの内周面に密着するのに伴って、熱交換部材Aは両者の間に挟まれる。   When the sleeve D is made of a photo-curing resin or a thermosetting resin, the sleeve A is conveyed to the site in a flexible state, and is inserted into a target pipe line by a reversing method or a retracting method. The Thereafter, compressed air is supplied to the inside of the sleeve D to expand the sleeve D, thereby closely contacting the inner surface of the pipe C. As the sleeve D comes into close contact with the inner peripheral surface of the pipe C, the heat exchange member A is sandwiched between them.

更に、スリーブDの内部から光を照射し或いは加熱することで、光硬化性樹脂或いは熱硬化性樹脂を硬化させることによって、スリーブDを管路Cの内部に配置すると共に、硬化したスリーブDと管路Cの内周面との間に挟んだ熱交換部材Aを、安定した状態を維持して両者の間に敷設することが可能である。   Furthermore, by irradiating or heating light from the inside of the sleeve D, the photocurable resin or the thermosetting resin is cured, whereby the sleeve D is disposed inside the pipe C, and the cured sleeve D The heat exchange member A sandwiched between the inner peripheral surface of the pipe C can be laid between the two while maintaining a stable state.

管路に光硬化性樹脂或いは熱硬化性樹脂からなるスリーブDを配置した場合、経時的な劣化や何等かの原因でスリーブDを補修する際に該スリーブDを加熱しても軟化することがない。このため、硬化したスリーブDを管路から排除する作業は容易ではない、という問題が生じることがある。しかし、熱硬化性樹脂からなるスリーブDは硬化した後の強度が高いため、劣化した管路Cに配置したとき、充分に自立した更生管を構成することが可能となる。   When the sleeve D made of a photo-curing resin or a thermosetting resin is arranged in the pipe, the sleeve D may be softened even if it is heated when repairing the sleeve D due to deterioration over time or for some reason. Absent. For this reason, the problem that the operation | work which removes the hardened | cured sleeve D from a pipe line is not easy may arise. However, since the sleeve D made of a thermosetting resin has a high strength after being cured, it is possible to form a sufficiently self-supported rehabilitation pipe when arranged in the deteriorated pipe line C.

次に、本発明に係る第2の施工方法について図9により説明する。この施工方法は、管路Cを構成する既設管Cがポリエチレンや塩化ビニルに代表される合成樹脂管によって構成される場合、或いは管路Cが既に合成樹脂からなるライニング材によって補修されている場合に適用して有利である。   Next, a second construction method according to the present invention will be described with reference to FIG. In this construction method, when the existing pipe C constituting the pipe C is constituted by a synthetic resin pipe represented by polyethylene or vinyl chloride, or when the pipe C is already repaired by a lining material made of synthetic resin. It is advantageous to apply to.

本実施例に於いて、図に示すように、管路Cの内周面は既にスリーブDによってライニングされることで補修されている。熱交換部材Aは前述した第1の施工方法と同様な手順で管路Cの内部に挿通される。   In the present embodiment, as shown in the drawing, the inner peripheral surface of the pipe C has already been repaired by being lined by a sleeve D. The heat exchange member A is inserted into the pipe C in the same procedure as the first construction method described above.

熱交換部材Aを管路Cの内周面となるスリーブDの内周面に挿通する際に、熱交換部材AのスリーブDと対向する面、及び又はスリーブDの内周面であって熱交換部材Aが配置される面に接着剤を塗布しておき、熱交換部材AをスリーブDの内周面に挿通したときに両者を接着する。このとき、熱交換部材AをスリーブDの底面側であって中央部分がスリーブDの最低部分と対応するように配置し、且つスリーブDの内周面に沿わせて正確に配置することは前述の施工方法と同様である。   When the heat exchange member A is inserted through the inner peripheral surface of the sleeve D, which is the inner peripheral surface of the pipe C, the surface of the heat exchange member A that faces the sleeve D and / or the inner peripheral surface of the sleeve D is heated. An adhesive is applied to the surface on which the exchange member A is disposed, and when the heat exchange member A is inserted through the inner peripheral surface of the sleeve D, both are bonded. At this time, the heat exchanging member A is disposed on the bottom surface side of the sleeve D so that the central portion thereof corresponds to the lowest portion of the sleeve D, and is accurately disposed along the inner peripheral surface of the sleeve D. This is the same as the construction method.

管路Cに挿入された熱交換部材AをスリーブDと接着することによって、管路Cの内部を水が流れたときに生じる浮力によって熱交換部材Aが浮き上がることを防ぐことが可能である。   By adhering the heat exchange member A inserted into the pipe C to the sleeve D, it is possible to prevent the heat exchange member A from being lifted by buoyancy generated when water flows through the pipe C.

上記の如くして熱交換部材Aを管路Cの内部に敷設することが可能である。しかし、熱交換部材Aの幅方向の両端部分が図1又は図2(a)、(b)のように筒体1の外形と同様な形状である場合、スリーブDとの間に段差が形成されて管路Cを流れる水に含まれたゴミが付着しやすくなる虞がある。このため、熱交換部材AをスリーブDに接着して管路Cの内部に配置した後、該熱交換部材Aの幅方向の両端部分に肉盛部25を形成することで、両者の間の段差を解消しておくことが好ましい。   As described above, the heat exchange member A can be laid inside the pipe C. However, when both end portions in the width direction of the heat exchange member A have the same shape as the outer shape of the cylindrical body 1 as shown in FIG. 1 or FIGS. In this case, dust contained in the water flowing through the pipe C may be easily attached. For this reason, after adhering the heat exchange member A to the sleeve D and arranging the heat exchange member A inside the pipe C, by forming the built-up portions 25 at both end portions in the width direction of the heat exchange member A, It is preferable to eliminate the step.

本施工方法では、熱交換部材Aが管路Cを流れる水に沈没したように配置されるため、筒体1に流通する熱交換媒体と水との間で円滑で効率的な熱交換を実現することが可能である。   In this construction method, the heat exchange member A is arranged as if it was sunk in the water flowing through the pipe C. Therefore, smooth and efficient heat exchange between the heat exchange medium flowing in the cylinder 1 and the water is realized. Is possible.

本発明に係る熱交換部材は構造が簡単であり、管路を流れる水の熱を活用して冷暖房用の熱源や融雪用の熱源などに利用して有利である。また、施工方法は、前記熱交換部材を管路に敷設する際に利用して有利である。   The heat exchanging member according to the present invention has a simple structure, and is advantageously used as a heat source for cooling and heating, a heat source for melting snow, and the like by utilizing the heat of water flowing through the pipe. Moreover, the construction method is advantageous when it is used for laying the heat exchange member on a pipe line.
