以下、本発明の好適な実施の形態について図面を参照しながら詳細に説明する。なお、以下に説明する本実施形態は、特許請求の範囲に記載された本発明の内容を不当に限定するものではなく、本実施形態で説明される構成の全てが本発明の解決手段として必須であるとは限らない。 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the present embodiment described below does not unreasonably limit the content of the present invention described in the claims, and all the configurations described in the present embodiment are essential as a means for solving the present invention. Is not always the case.
図１は、本発明の一実施形態に係る通水・排水材の斜視図である。本発明の一態様は、縦横方向に凸部と凹部を交互に有する巻回部材１１が少なくとも１周以上巻回され、巻回された巻回部材１１の最外周には被覆部材１２が備えられていることを特徴とする通水・排水材１０である。 FIG. 1 is a perspective view of a water flow / drainage material according to an embodiment of the present invention. In one aspect of the present invention, a winding member 11 having convex portions and concave portions alternately in the vertical and horizontal directions is wound at least one turn, and a covering member 12 is provided on the outermost circumference of the wound winding member 11. It is a water passage / drainage material 10 characterized by the fact that it is used.
なお、図１では、通水・排水材１０の中心部分に後述する中空円筒管１３が設けられているが、中空円筒管１３は本発明の一実施形態に係る通水・排水材１０の必須の構成ではない。通水・排水材１０の中心に中空円筒管１３がある場合は、巻回部材を安定して巻回することができ、また、後述するように、複数の巻回された巻回部材を連結するという役割を果たすという利点がある。 In FIG. 1, a hollow cylindrical tube 13 described later is provided at the central portion of the water flow / drainage material 10, but the hollow cylindrical tube 13 is essential for the water flow / drainage material 10 according to the embodiment of the present invention. It is not the composition of. When the hollow cylindrical tube 13 is located at the center of the water flow / drainage material 10, the winding member can be wound stably, and a plurality of wound winding members are connected as described later. It has the advantage of playing the role of doing.
図１に示すように、通水・排水材１０は、中空円筒管１３を中心に有し、巻回部材１１は中空円筒管１３の周りを巻回しているようにしてもよい。中空円筒管１３は用途に応じ側面に複数の通水孔を設けることが出来る。後述するように、中空円筒管１３の直径や通水孔の数、巻回部材１１の巻き数等を適宜組み合わせることにより、集水と排水のそれぞれに対応することができ多用途に使用することができる通水・排水材１０となる。以下、通水・排水材１０の各構成について説明する。 As shown in FIG. 1, the water flow / drainage material 10 may have a hollow cylindrical tube 13 at the center, and the winding member 11 may be wound around the hollow cylindrical tube 13. The hollow cylindrical tube 13 can be provided with a plurality of water passage holes on the side surface depending on the application. As will be described later, by appropriately combining the diameter of the hollow cylindrical tube 13, the number of water passage holes, the number of turns of the winding member 11, etc., it is possible to deal with each of water collection and drainage, and it can be used for various purposes. It becomes the water flow / drainage material 10 that can be used. Hereinafter, each configuration of the water flow / drainage material 10 will be described.
巻回部材１１は、例えば塩化ビニル、ポリプロピレン、ポリエチレン、その他の樹脂材料を用いて形成される。このような材質を選択することで、通水・排水材１０の軽量化を実現することができる。また、巻回部材１１は、その縦横方向に凸部と凹部を交互に有し、例えばエンボス加工が施されていることが好ましい。通水・排水材１０を集水・排水材として用いる場合には、巻回部材１１には複数の通水孔が設けられており、巻回部材１１の中を通って地中と中空円筒管１３の間も水が通るようになっている。通水孔の数や大きさは、通水・排水材１０の用途（排水用か集水用か等）や規模（どの程度の水の移動が生じるか）などに応じて適宜決定される。なお、通水・排水材１０を通水材として用いる場合などには、通水孔は無くてもよい。 The winding member 11 is formed by using, for example, vinyl chloride, polypropylene, polyethylene, or other resin material. By selecting such a material, it is possible to reduce the weight of the water flow / drainage material 10. Further, it is preferable that the winding member 11 has convex portions and concave portions alternately in the vertical and horizontal directions thereof, and is, for example, embossed. When the water flow / drainage material 10 is used as the water collection / drainage material, the winding member 11 is provided with a plurality of water passage holes, and passes through the winding member 11 to the ground and a hollow cylindrical tube. Water can pass through between 13. The number and size of the water passage holes are appropriately determined according to the use (drainage or water collection, etc.) and scale (how much water movement occurs) of the water passage / drainage material 10. When the water passage / drainage material 10 is used as a water passage material, the water passage hole may not be provided.
被覆部材１２は、巻回された巻回部材１１の最外周に備えられる。被覆部材１２は、例えばポリエステル製またはポリプロピレン製の不織布や、塩ビ被覆ポリエステル製メッシュ等の透水性部材から形成され、熱溶着等によって巻回部材１１に接着される。あるいは後述するように、被覆部材１２を筒状又は袋状とし、その内部に巻回部材１１を入れるような構成としてもよい。また、用途に応じて被覆部材１２を不透水性部材で形成してもよい。 The covering member 12 is provided on the outermost circumference of the wound winding member 11. The covering member 12 is formed of a water-permeable member such as a non-woven fabric made of polyester or polypropylene or a mesh made of vinyl chloride-coated polyester, and is adhered to the winding member 11 by heat welding or the like. Alternatively, as will be described later, the covering member 12 may have a tubular shape or a bag shape, and the winding member 11 may be inserted therein. Further, the covering member 12 may be formed of an impermeable member depending on the application.
中空円筒管１３は、通水・排水材１０の略中央部分を貫通する中空の円筒管であり、用途に応じて側面に複数の通水孔を設けてもよい。その場合通水孔は数ｍｍ程度の貫通孔であり、この通水孔を通して中空円筒管１３と巻回部材１１間の水平方向に水が移動する。通水孔の数や大きさは、巻回部材１１と同様に適宜決定される。通水孔は、例えばドリル等を用いて形成すればよい。本発明の一実施形態に係る通水・排水材１０は、中空円筒管１３に巻回部材１１を巻回させるという簡易な構造で製造することができるため、これらの設計変更も容易に行うことができる。中空円筒管１３の材質は特に限定はされないが、例えば、合成樹脂製可とう管などが低コストで入手可能であるため好ましく用いられる。 The hollow cylindrical pipe 13 is a hollow cylindrical pipe that penetrates a substantially central portion of the water passage / drainage material 10, and a plurality of water passage holes may be provided on the side surface depending on the application. In that case, the water passage hole is a through hole of about several mm, and water moves in the horizontal direction between the hollow cylindrical tube 13 and the winding member 11 through the water passage hole. The number and size of the water passage holes are appropriately determined in the same manner as in the winding member 11. The water passage hole may be formed by using, for example, a drill or the like. Since the water flow / drainage material 10 according to the embodiment of the present invention can be manufactured with a simple structure in which the winding member 11 is wound around the hollow cylindrical tube 13, these design changes can be easily performed. Can be done. The material of the hollow cylindrical tube 13 is not particularly limited, but for example, a flexible tube made of synthetic resin is preferably used because it is available at low cost.
図２は、複数の巻回部材を嵌合する態様を説明するための断面図である。巻回部材は上述したように、縦横方向に凸部と凹部を交互に有する形状であるため、凸部と凹部の形状が同じ巻回部材同士であれば、図２（Ａ）のように、巻回前の巻回部材３１Ａと３１Ｂの端部付近を嵌合して連結することができる。あるいは、図２（Ｂ）のように、連結用の（比較的短い長さの）接続部材（巻回部材）３１Ｃにより、巻回部材３１Ａ、３１Ｂ同士を連結することもできる。このようにして連結した巻回部材を巻回することにより通水・排水材を形成することができる。 FIG. 2 is a cross-sectional view for explaining a mode in which a plurality of winding members are fitted. As described above, the winding member has a shape having convex portions and concave portions alternately in the vertical and horizontal directions. Therefore, if the winding members have the same shape of the convex portions and the concave portions, as shown in FIG. The vicinity of the ends of the winding members 31A and 31B before winding can be fitted and connected. Alternatively, as shown in FIG. 2B, the winding members 31A and 31B can be connected to each other by the connecting member (winding member) 31C for connection (relatively short length). By winding the winding members connected in this way, a water flow / drainage material can be formed.
図２（Ｂ）に示す態様について、さらに詳しく説明する。図３（Ａ）〜（Ｄ）は、接続部材を用いて複数の巻回部材を接続する態様を説明するための斜視図であり、図３（Ａ）は、接続部材を重ね合わせる前、図３（Ｂ）は、接続部材を重ね合わせた時、図３（Ｃ）は、接続部材とともに巻回部材を接合した時、図３（Ｄ）は、接続後に外周を被覆部材で覆った時の図である。 The embodiment shown in FIG. 2B will be described in more detail. 3 (A) to 3 (D) are perspective views for explaining a mode in which a plurality of winding members are connected by using a connecting member, and FIG. 3 (A) is a view before overlapping the connecting members. 3 (B) shows when the connecting members are overlapped, FIG. 3 (C) shows when the winding member is joined together with the connecting member, and FIG. 3 (D) shows when the outer circumference is covered with a covering member after the connection. It is a figure.
まず、図３（Ａ）に示すように、接合しようとする２つの巻回部材３１Ａ、３１Ｂを用意する。このとき、それぞれの巻回部材３１Ａ、３１Ｂの一部を巻回しない状態で伸ばしておき、それぞれの巻回部材３１Ａ、３１Ｂの端部同士を突き合わせる。それぞれの巻回部材３１Ａ、３１Ｂ、及び、接合部材３１Ｃには、同じように凸部３５Ａ、３５Ｂ、３５Ｃと、凹部３６Ａ、３６Ｂ、３６Ｃが縦横交互に形成されている。したがって、図３（Ｂ）に示すように、突き合わせたそれぞれの巻回部材３１Ａ、３１Ｂの端部を覆うように接合部材３１Ｃを重ね合わせることができる。この時、接合部材３１Ｃに形成された凸部３５Ｃ、凹部３６Ｃが、それぞれの巻回部材３１Ａ、３１Ｂの凸部３５Ａ、３５Ｂ、及び、凹部３６Ａ、３６Ｂと嵌合する。 First, as shown in FIG. 3A, two winding members 31A and 31B to be joined are prepared. At this time, a part of the winding members 31A and 31B is stretched without being wound, and the ends of the winding members 31A and 31B are abutted against each other. Similarly, convex portions 35A, 35B, 35C and concave portions 36A, 36B, 36C are formed in the winding members 31A, 31B and the joining member 31C alternately in the vertical and horizontal directions. Therefore, as shown in FIG. 3B, the joining members 31C can be overlapped so as to cover the ends of the abutted winding members 31A and 31B, respectively. At this time, the convex portions 35C and the concave portions 36C formed on the joining member 31C are fitted with the convex portions 35A and 35B and the concave portions 36A and 36B of the winding members 31A and 31B, respectively.
この状態で、図３（Ｃ）に示すように、接合部材３１Ｃごと、突き合わせた巻回部材３１Ａ、３１Ｂの残りの部分を巻回する。これにより、それぞれの巻回部材３１Ａ、３１Ｂと接合部材３１Ｃの凹凸部分がかみ合い一体化する。それぞれの巻回部材３１Ａ、３１Ｂと接合部材３１Ｃの境界部分は、テープ３７Ａ、３７Ｂなどで固定してもよい。最後に、図３（Ｄ）に示すように外周を被覆部材３２で覆うことにより、連結した一つの通水・排水材３０とすることができる。 In this state, as shown in FIG. 3C, the remaining portions of the abutted winding members 31A and 31B are wound together with the joining member 31C. As a result, the concavo-convex portions of the winding members 31A and 31B and the joining member 31C are engaged and integrated. The boundary portion between the winding members 31A and 31B and the joining member 31C may be fixed with tapes 37A, 37B or the like. Finally, as shown in FIG. 3D, by covering the outer periphery with the covering member 32, one connected water / drainage material 30 can be obtained.
このような構成にすることにより現場においても容易に接続ができ、例えば、５ｍの長さの通水・排水材を連結して巻回することで１０ｍでも２０ｍでも製品化可能で、製品延長の自由度がある。 With such a configuration, it can be easily connected even in the field. For example, by connecting and winding a water flow / drainage material with a length of 5 m, it can be commercialized at 10 m or 20 m, and the product can be extended. There is a degree of freedom.
また、本発明の実施形態に係る通水・排水材では、巻回された巻回部材は中空円筒管に対して挿脱可能であり、運搬や施工に適した長さに分割された複数の巻回部材が中空円筒管に巻回されているようにしてもよい。図４（Ａ）は、被覆部材を備える巻回部材が複数に分割されている場合の通水・排水材の態様を表す側面図である。 Further, in the water flow / drainage material according to the embodiment of the present invention, the wound winding member can be inserted into and removed from the hollow cylindrical pipe, and a plurality of wound members are divided into lengths suitable for transportation and construction. The winding member may be wound around a hollow cylindrical tube. FIG. 4A is a side view showing the mode of the water flow / drainage material when the winding member including the covering member is divided into a plurality of parts.
さらに、別態様例として、本発明の実施形態に係る通水・排水材では、最外周に筒状又は袋状の被覆部材を備え、内部に運搬や施工に適した長さに分割され、巻回された複数の巻回部材を有するようにしてもよい。図４（Ｂ）は、筒状の被覆部材の中で巻回部材が複数に分割されている場合の通水・排水材の他の態様を表す断面図である。 Further, as another example, the water flow / drainage material according to the embodiment of the present invention is provided with a tubular or bag-shaped covering member on the outermost circumference, and is internally divided into lengths suitable for transportation and construction, and wound. It may have a plurality of wound members that have been rotated. FIG. 4B is a cross-sectional view showing another aspect of the water flow / drainage material when the winding member is divided into a plurality of parts in the tubular covering member.

図６は、本発明の一実施形態に係る通水・排水材の概略断面図である。本発明の一態様では、巻回部材１１を巻回すると例えば図６に示すように凸部と凹部が複雑にかみ合う状態となる。これにより、本発明の一実施形態に係る通水・排水材１０は、優れた強度と柔軟性を備えることができる。本発明の一実施形態に係る通水・排水材１０は、その用途に応じて、通水・排水材１０の径ＤＡと、中空円筒管１３の径ＤＣの比を適宜変更して設計することが望ましい。これらの径の長さの比は、中空円筒管１３の太さや、巻回部材１１の中空円筒管１３に対する巻き数、被覆部材１１の種類等を変更することで調整することができる。 FIG. 6 is a schematic cross-sectional view of a water flow / drainage material according to an embodiment of the present invention. In one aspect of the present invention, when the winding member 11 is wound, for example, as shown in FIG. 6, the convex portion and the concave portion are in a complicated meshing state. As a result, the water flow / drainage material 10 according to the embodiment of the present invention can have excellent strength and flexibility. Passing water and wastewater member 10 according to an embodiment of the present invention, depending on the application, the diameter D A of the water passage and drainage material 10, by appropriately changing the ratio of the diameter D C of the hollow cylindrical tube 13 designed It is desirable to do. The ratio of the lengths of these diameters can be adjusted by changing the thickness of the hollow cylindrical tube 13, the number of turns of the winding member 11 with respect to the hollow cylindrical tube 13, the type of the covering member 11, and the like.
以上説明してきたように、本発明の一実施形態に係る通水・排水材は、巻回部材を巻いて中実な通水部を作ることで、巻き数によって簡単に管の直径（通水断面）を変更することが出来るため、設計変更が容易である。また、巻回部材は、塩化ビニルやポリエチレン等で形成されるため、軽量であり、持ち運びあるいは接続等が簡便で、設置埋設が容易である。また、通常の有孔パイプに比べて安価に作成することができる。 As described above, the water flow / drainage material according to the embodiment of the present invention is easily formed by winding a winding member to form a solid water passage portion, so that the diameter of the pipe (water flow) can be easily determined by the number of turns. Since the cross section) can be changed, it is easy to change the design. Further, since the winding member is made of vinyl chloride, polyethylene, or the like, it is lightweight, easy to carry or connect, and easy to install and bury. Moreover, it can be produced at a lower cost than a normal perforated pipe.
さらに、巻回部材を巻回することにより、耐圧性にも優れ、過剰な圧力下でも粘り強く追随変形し、破壊や破損に至りにくいため従来の塩ビ管やプラスチック管よりも優れている。また、柔軟に変形しながらも、圧力下の通水断面積を維持することができるため柔軟なホースやポリパイプに比べても優れている。さらに、上述したような接続部材を用いることにより、通水・排水材の接続部分も一体化するため破断しにくいだけでなく、変形への追随性も高くなる。しかも接着剤を使用しない方法で簡便に接続可能となる。 Further, by winding the winding member, it has excellent pressure resistance, is tenaciously deformed even under excessive pressure, and is less likely to be broken or damaged, so that it is superior to conventional PVC pipes and plastic pipes. In addition, it is superior to flexible hoses and polypipes because it can maintain the cross-sectional area of water flow under pressure while being flexibly deformed. Further, by using the connecting member as described above, since the connecting portion of the water flow / drainage material is also integrated, not only is it difficult to break, but also the followability to deformation is improved. Moreover, it can be easily connected by a method that does not use an adhesive.
以上の通り、本発明の各実施形態及び各実施例について詳細に説明したが、本発明の新規事項及び効果から実体的に逸脱しない多くの変形が可能であることは、当業者には、容易に理解できるであろう。従って、このような変形例は、全て本発明の範囲に含まれるものとする。 As described above, each embodiment and each embodiment of the present invention have been described in detail, but it is easy for those skilled in the art to be able to make many modifications that do not substantially deviate from the new matters and effects of the present invention.
