Description
【考案の詳細な説明】
この考案はマンホールに接面する部分のコンクリートに
ついてのもので、その特徴はマンホール１の側面開口部
２に内部を円形３、外部を四角形４とするコンクリート
管５をあてがい、接続するようにしたことにある。[Detailed explanation of the invention] This invention concerns the part of the concrete in contact with the manhole, and its feature is that a concrete pipe 5 having a circular shape 3 on the inside and a square shape 4 on the outside is attached to the side opening 2 of the manhole 1. , I tried to connect it.

ホールの沈下圧と、コンクリート管の水平保持作用とに
よって、マンホールに近い部分においてコンクリート管
に折損を生ずる欠点があった。Conventionally, a cylindrical concrete pipe has been connected to the side opening of a manhole, so as shown in Figure 3, the concrete pipe closes to the manhole due to the sinking pressure of the manhole and the horizontal holding action of the concrete pipe. The problem was that it could break.
特に１０ ）−ン以上の大型車がひんばんに道路上を往
来するに至った今日では上記した欠点が従来以上に多く
生じている。Particularly in today's world, where large vehicles of 10 mm or more are frequently plying on the roads, the above-mentioned drawbacks are occurring more frequently than before.
本考案はマンホールに接続するコンクリート管５を内部

ンクリート管５は四隅を増圧して著しく強化されて上記
した折損を生じないものとなる。In the present invention, the concrete pipe 5 connected to the manhole has a circular interior and a rectangular exterior 4, so that the concrete pipe 5 in this area is significantly strengthened by increasing the pressure at the four corners, and does not cause the above-mentioned breakage. .
なお、コンクリ−Ｉ・管５の次に接続する多数の管は従
来通り外表も円形である円筒形のコンクリート管６とす
る。It should be noted that the many pipes connected next to the concrete I pipe 5 are cylindrical concrete pipes 6 whose outer surfaces are also circular, as in the past.
