【０００２】
【従来の技術】
近年、地下に張りめぐらされた下水管渠を利用した光ファイバーケーブルによる情報ネットワークの敷設を図ろうという提案がなされている。
この提案は、下水管渠が一般的に通水断面積に対して管断面積が大きいことに注目し、下水管渠の内部にケーブル管を敷設して、このケーブル管内に光ファイバーケーブルを挿通させ、下水管渠を情報伝達路として利用しようとするものである。
【０００３】
その目的で例えば実開昭６２ー１２５１８３号公報には、管体の管頂部の内面側若しくは外面側に管軸方向に沿って隔壁を設け、該隔壁と管体の管頂部管壁とでケーブル収納部を形成させた下水管が提案されている。
【０００４】
また、溶融樹脂を押し出し成形して、内部を管軸方向に沿って仕切り壁により上下に分離形成し、下水管本体内の上部通路に光ファイバーケーブルを挿通でき、下部通路に下水を流せるようにする下水管も提案されている。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記実開昭６２ー１２５１８３号公報に開示の下水管は、押し出し成形により成形すると、形成時における管内面の隔壁を形成する溶融樹脂の流れの調整が難しく、得られる下水管の隔壁が曲がってしまったり、ケーブル収納部が変形して閉塞してしまったりすることがあるという問題点がある。
【０００６】
また、上記仕切り壁を下水管本体の内部に一体的に形成する下水管では、地中に埋設した場合、下水管の上方からの土圧や、下水管本体内の上部通路に挿通した光ファイバーケーブルの重みにより、仕切り壁の左右の根元部分に応力集中が生じ、長期間の使用によりこの部分から亀裂が生じるといった懸念があった。
【０００７】
本発明は上記のような点に鑑みて開発されたものであり、その目的とするところは、上記のような問題点や懸念を解決し、優れたケーブル収納機能を有する下水管、並びに既成の下水管もケーブル収納機能を有する下水管にすることができる下水管内仕切り支持板部材を提供することにある。
【０００８】

【０００９】
請求項２記載の本発明の下水管は、下水管本体の内周面に沿って当接保持されるように形成してなる支持板部材を、下水管本体の管軸方向に沿って挿着し、上記支持板部材により、下水管本体内を下水流下部とケーブル収納部とに分離形成されていると共に、上記ケーブル収納部に長尺な仕切り板部材を挿着し、この仕切り板部材により、ケーブル収納部内を複数に区画されていることを特徴とする構成である。
【００１０】
請求項３記載の本発明の下水管は、請求項２の構成において、仕切り板部材のケーブル収納部側の外面に、管軸方向に沿って多数の溝を形成したことを特徴とする構成である。
【００１１】
請求項４記載の本発明の下水管は、請求項２の構成において、支持板部材に通水用穴を穿設すると共に、この支持板部材と接する仕切り板部材の底部にも通水穴を穿設したことを特徴とする構成である。
【００１２】
請求項５記載の本発明の下水管内仕切り支持板部材は、下水管本体の管軸方向に沿って挿入可能な支持面部と、下水管本体の内周面に当接保持されるように上記支持面部の両側に形成された支え側板部とからなることを特徴とする構成である。
【００１３】
請求項６記載の本発明の下水管内仕切り支持板部材は、請求項５の構成において、支持面部の長手方向に沿って立壁部を形成したことを特徴とする構成である。
【００１４】
【発明の実施の形態】
以下、本発明の実施の形態を図に基づいて説明する。
図１は本発明に係る下水管１の一例の横断面図であって、この下水管１は、下水管本体２と支持板部材３とによって構成されている。下水管本体２および支持板部材３は硬質ポリ塩化ビニル等の合成樹脂を押出成形して形成されたものである。
【００１５】
支持板部材３（図１、図３参照）は、下水管本体２内の上部寄りに挿入して管内を上下に分離できるように形成された長尺の支持面部４と、この支持面部４の両側に形成され下水管本体２の内周面５に沿って当接保持される彎曲形成され支え側板部６とからなる。この例では各支え側板部６は支持面部４の全側端に沿って形成されている。勿論、図８に示すように支持面部４の両側端の両端にのみ支え側板部６を形成した支持板部材３であってもよい。また、支持面部４の両側端の適宜箇所に間欠的に形成したものであってもよい。
【００１６】
上記の支持板部材３を図１に示すように両側の各支え側板部６を内側に窄めるようにして下水管本体２に挿入することにより、支持板部材３の両側の各支え側板部６が、下水管本体２内で外方に拡がろうと（復元）する弾発力により、下水管本体２の内周面５に沿って押圧して当接し、支持板部材３全体が下水管本体２内に保持されることになる。このことにより下水管本体２内は上下に分離され下水流下部７とケーブル収納部８に区画される。
【００１７】
なお、各支え側板部６の外面に接着剤を塗布して下水管本体２の内周面５に接着するようにして取り付けてもよい。また、支持板部材３は、図９に示すように支持面部４を水平状に形成して両側に上記と同様の各支え側板部６を形成したものであってもよい。この場合も支持板部材３の両側の支え側板部６を内側に窄めるようにして下水管本体２内に挿入することにより、管内で両支え側板部６が外方に拡がって、支持板部材３は下水管本体２の内周面５に当接保持される。
【００１８】
下水流下部７には下水が流れ、ケーブル収納部８には光ファイバーケーブル９が挿着される。この挿着された光ファイバーケーブル９の重さに対しても支持板部材３の両側の各支え側板部６が、下水管本体２の内周面５を押圧するようにして支持するため、支持面部４と各支え側板部６の境目部分に悪影響を及ぼすような応力のかかるのを極力防止することができる。
【００１９】
図２は上記の下水管１の支持板部材３の上にさらに横断面逆Ｔ字状の長尺な仕切り板部材１０を支持面部４の長手方向にそって挿着した下水管１ａである。このようにケーブル収納部８に仕切り板部材１０を挿着することによって内部をさらに２区画にして光ファイバーケーブル１０を区分けして挿入することができる。なお、仕切り板部材１０は上記のような横断面逆Ｔ字状に限らず、ケーブル収納部８内を複数に区画できれば如何なる形状のものであってもよい。
【００２０】
また、図４に示すように上記仕切り板部材１０のケーブル収納部側の外面に、管軸方向に沿って多数の溝１１を形成することにより、挿入する光ファイバーケーブル１０の外面との接触面積が少なくなり、摩擦抵抗も小さくなってよりスムーズに光ファイバーケーブル１０を挿入することができる。
【００２１】
また、図５、図７に示すように上記仕切り板部材１０の底部１２に多数の通水穴１３を穿設すると共に、上記支持板部材３の支持面部４にも多数の通水穴１４を穿設することにより、ケーブル収納部８内に下水が流入してもこれらの通水穴１３，１４を通って素早く水切りをすることができる。
【００２２】
また、図６に示すように支持板部材３の支持面部４に長手方向に沿って立壁部１５を形成することにより、上記のような仕切り板部材１０を別に使用しなくともケーブル収納部８内を上記のように区画することができる。勿論、立壁部１５は支持面部４の横断面中央に限らず右寄りでも左寄りであってもよい。また、２つ以上の立壁部１５を形成して２区画以上にケーブル収納部８を区画してもよい。また、長手方向に対しては間欠的に立壁部１５が形成されていてもよい。
【００２３】
なお、下水管本体の形状は、断面外径が円形のものに限らず、一般に下水分野で使用される断面外径がいわゆる卵形のもの、外面にリブ構造を有するもの、管肉厚部内の管軸方向に沿って多数の小孔が設けられるようにして厚肉とされ剛性を高めた物等も挙げられる。
【００２４】
また、下水管本体の材質は、ポリ塩化ビニル、ポリエチレン、ポリプロピレン、ポリフェニレンサルファイド等が挙げられるが、中でもポリ塩化ビニルが好ましい。下水管本体の厚みは、材質がポリ塩化ビニルである場合には、下水管用ポリ塩化ビニル管のＪＩＳ規格と同じである。
【００２５】
【発明の効果】
以上、上述のように請求項１記載の本発明の下水管では、下水管本体内を支持板部材を挿着することにより簡単に下水流下部とケーブル収納部とに分離形成することができる。また、下水管本体に対する土圧や、ケーブル収納部に挿着した光ファイバーケーブルの重さが支持板部材に作用しても、これらの作用力を支持板部材の両側の支え側板部が下水管本体の内周面に面接触して当接保持するため、長期間の下水管の使用に対しても支持板部材に亀裂が生じるといったこともない。
【００２６】
請求項２記載の本発明の下水管では、下水管本体内部を下水流下部とケーブル収納部に簡単に分離形成できると共に、ケーブル収納部に仕切り板部材を挿着することにより、ケーブル収納部内をさらに区画することができ、光ファイバーケーブルの種類等によって振り分け収納することができる。
【００２７】
請求項３記載の本発明の下水管では、仕切り板部材のケーブル収納部側に多数の溝を形成したことにより、光ファイバーケーブルをケーブル収納部に挿入する場合でもこれらの溝に案内され、且つ光ファイバーケーブルと仕切り板部材との接触面積も少なくなりよりスムーズに光ファイバーケーブルを挿入することができる。
【００２８】
請求項４記載の本発明の下水管では、下水管本体内を仕切る支持板部材およびケーブル収納部を区画する仕切り板部材に通水穴を穿設したことにより、増水等により下水がケーブル収納部に流入した場合でも、流入した下水が減水とともに自然に速やかに通水穴から下方に流れ出ることができる。
【００２９】
請求項５記載の本発明の下水管内仕切り支持板部材では、この支持板部材を下水管本体内に挿着することにより、両側の支え側板部が内周面に当接保持され、簡単に下水管内をケーブル収納部と下水流下部とに分離形成することができる。また、既製の下水管にも挿着することができるため、光ファイバーケーブル挿着用の専用下水管を成形しなくともよく経済的である。
【００３０】
請求項６記載の本発明の下水管内仕切り支持板部材では、支持面部の長手方向に沿って立壁部を形成したことにより、下水管本体内に挿着した支持板部材の上にさらに仕切り板部材を挿着してケーブル収納部を区画しなくとも、支持板部材だけでケーブル収納部を左右に区画することができ、非常に経済的で且つ光ファイバーケーブルを挿着できる下水管の施工時間も短縮することができる。

[0018]
Sewage flows through the sewage flow lower portion 7, and an optical fiber cable 9 is inserted into the cable storage portion 8. Since the supporting side plate portions 6 on both sides of the supporting plate member 3 support the inner peripheral surface 5 of the sewer pipe body 2 against the weight of the inserted optical fiber cable 9 as well, the supporting surface portion 4 and the support side plate 6 can be prevented from being stressed as much as possible.
[0019]
FIG. 2 shows a sewage pipe 1 a in which a long partition plate member 10 having a reverse T-shaped cross section is further inserted along the longitudinal direction of the support surface portion 4 on the support plate member 3 of the sewage pipe 1. In this way, by inserting the partition plate member 10 into the cable storage portion 8, the optical fiber cable 10 can be divided and inserted by further dividing the inside into two sections. The partition plate member 10 is not limited to the reverse T-shaped cross section as described above, and may have any shape as long as the inside of the cable storage portion 8 can be divided into a plurality of parts.
[0020]
Moreover, as shown in FIG. 4, the contact area with the outer surface of the optical fiber cable 10 to insert is formed by forming many groove | channels 11 along the pipe-axis direction in the outer surface by the side of the cable storage part of the said partition plate member 10. As shown in FIG. The optical fiber cable 10 can be inserted more smoothly with less frictional resistance.
[0021]

By drilling, even if sewage flows into the cable housing portion 8, the water can be quickly drained through the water holes 13 and 14.
[0022]
Further, as shown in FIG. 6, by forming the standing wall portion 15 along the longitudinal direction on the support surface portion 4 of the support plate member 3, the inside of the cable storage portion 8 can be used without using the partition plate member 10 as described above. Can be partitioned as described above. Of course, the standing wall portion 15 is not limited to the center of the cross section of the support surface portion 4, and may be on the right side or on the left side. Two or more standing wall portions 15 may be formed to divide the cable storage portion 8 into two or more sections. Moreover, the standing wall part 15 may be intermittently formed with respect to the longitudinal direction.
[0023]
The shape of the sewage pipe main body is not limited to the one having a circular cross-sectional outer diameter, but generally has a so-called oval cross-sectional outer diameter used in the sewage field, one having a rib structure on the outer surface, The thing etc. which were thickened so that many small holes could be provided along a pipe-axis direction, and were improved in rigidity are mentioned.
[0024]
Examples of the material of the sewage pipe main body include polyvinyl chloride, polyethylene, polypropylene, polyphenylene sulfide, etc. Among them, polyvinyl chloride is preferable. When the material is polyvinyl chloride, the thickness of the main body of the sewage pipe is the same as the JIS standard of the polyvinyl chloride pipe for the sewage pipe.

【The invention's effect】
As described above, in the sewage pipe according to the first aspect of the present invention, the support plate member can be inserted into the sewage pipe main body so as to be easily separated into the sewage flow lower part and the cable housing part. Moreover, even if the earth pressure against the sewage pipe main body or the weight of the optical fiber cable inserted into the cable storage part acts on the support plate member, the supporting side plate parts on both sides of the support plate member are affected by these acting forces. Since the inner peripheral surface of the sewage pipe is brought into contact with and held in contact, the support plate member is not cracked even when the sewage pipe is used for a long time.
[0026]
In the sewage pipe according to the second aspect of the present invention, the inside of the sewage pipe body can be easily separated and formed into the lower part of the sewage flow and the cable storage part, and the partition plate member is inserted into the cable storage part, thereby It can be further divided and can be sorted and stored according to the type of optical fiber cable.
[0027]
In the sewage pipe according to the third aspect of the present invention, since a large number of grooves are formed on the side of the cable storage portion of the partition plate member, even when the optical fiber cable is inserted into the cable storage portion, it is guided to these grooves, and the optical fiber The contact area between the cable and the partition plate member is also reduced, and the optical fiber cable can be inserted more smoothly.
[0028]
According to the sewage pipe of the present invention as set forth in claim 4, sewage is supplied to the cable storage part by increasing water or the like by forming a water passage hole in the support plate member partitioning the inside of the sewage pipe main body and the partition plate member partitioning the cable storage part. Even if it flows into the sewage, the sewage that has flowed in can flow down downward from the water hole naturally and quickly.
[0029]
In the sewage pipe partition support plate member according to the fifth aspect of the present invention, by inserting the support plate member into the sewage pipe main body, the support side plate portions on both sides are held in contact with the inner peripheral surface, so that the sewage can be easily treated. The inside of a pipe | tube can be separately formed in a cable storage part and a sewer lower part. Moreover, since it can also be inserted into a ready-made sewage pipe, it is economical without forming a dedicated sewage pipe for inserting an optical fiber cable.
[0030]
In the sewage pipe partition support plate member of the present invention according to claim 6, the partition plate member is further formed on the support plate member inserted into the sewage pipe main body by forming the standing wall portion along the longitudinal direction of the support surface portion. Even if the cable storage part is not partitioned by inserting the cable, the cable storage part can be partitioned right and left with only the support plate member, which is very economical and shortens the construction time of the sewer pipe to which the optical fiber cable can be inserted. can do.
