(57) [Summary] [Objective] The range of the diameter of the fitting (4) attached to the sewer manhole body (1) is expanded to improve the efficiency and certainty of pipe work. [Composition] The thickness of the inside of the side wall of the pipe connection part of the manhole body is increased, and a cylindrical hole is opened in this part from the bottom surface to near the bottom of the foot fitting (5) like a flat wall (2). A structure for increasing the effective length of (3).
Description
【０００１】[0001]
この考案は、下水道用マンホールに関するものである。 This invention relates to a sewer manhole.
【０００２】[0002]
マンホール本体（１）の側壁の厚さは、従来の厚さで機能的には十分である。 近年の管接続用の継手（４）の向上、普及によって従来の側壁の厚さでは、これ らの継手（４）が装着でないケースが出ている。 この場合、継手（４）を他のものに代えて施工しているが、漏水の不安がある。 As for the thickness of the side wall of the manhole body (1), the conventional thickness is functionally sufficient. Due to the improvement and popularization of the joints (4) for pipe connection in recent years, there are cases where these joints (4) are not attached with the conventional side wall thickness. In this case, the joint (4) is constructed by replacing it with another one, but there is concern about water leakage.
【０００３】[0003]
側壁は特定の半径を持った曲面となっている。この側壁に円筒孔（３）を明け て、継手（４）を差込み固定しているが、継手（４）の口径が大きくなると、円 筒孔（３）に継手（４）の固定部分がおさまりきらずに、はみ出てしまう部分が ある。 この状態になると継手（４）の水密性不良や脱落の原因となる。 本考案は、この問題を解決しようとするものである。 The side wall is a curved surface with a specific radius. Cylindrical hole (3) is opened in this side wall and fitting (4) is inserted and fixed. However, when the diameter of fitting (4) becomes large, the fixed part of fitting (4) fits into cylindrical hole (3). There is a part that sticks out without being cut off. In this state, the watertightness of the joint (4) may be poor and the joint (4) may fall off. The present invention seeks to solve this problem.
【０００４】[0004]
マンホール本体（１）の管接続部分に相当する側壁の内側の曲面を平面壁（２ ）となるように厚さを増して、継手用の円筒孔（３）の有効長を長くして、継手 （４）が円筒孔（３）内に完全に固定できるようにする。 The inner curved surface of the side wall corresponding to the pipe connection portion of the manhole body (1) is increased in thickness so as to become the flat wall (2), and the effective length of the cylindrical hole (3) for the joint is lengthened to make the joint. Allow (4) to be completely fixed in the cylindrical hole (3).
【０００５】[0005]
管接続部分の側壁の内側が厚くなっているので、ここに差込む継手（４）の固 定部（７）が円筒孔（３）の中におさまり、漏水や脱落の心配がなく、完全に固 定できる。 Since the inside of the side wall of the pipe connection part is thick, the fixed part (7) of the joint (4) that is inserted here is housed in the cylindrical hole (3), and there is no risk of water leakage or falling off, and it is completely Can be fixed.
【０００６】[0006]
実施例１ 図１は、実施例１を示す斜視図である。 実施例１のものではマンホール本体（１）の管接続部分に相当する側壁の内側 の底面から足掛金物（５）の下付近まで厚さを増して平面壁（２）として、この 部分に明ける円筒孔（３）の有効長を長くする構造。 Example 1 FIG. 1 is a perspective view showing Example 1. In the first embodiment, the thickness is increased from the inner bottom surface of the side wall corresponding to the pipe connecting portion of the manhole body (1) to near the bottom of the foot latch (5) to form a flat wall (2), which is exposed at this portion. A structure for increasing the effective length of the cylindrical hole (3).
【０００７】 実施例２ 図２は実施例２を示す立断面図である。 実施例２のものではマンホール本体（１）の２ケ所の管接続部（流出管側およ び流入管側）の内側を実施例１のものと同様に厚さを増して平面壁（２）として 円筒孔（３）の有効長を長くする構造。Second Embodiment FIG. 2 is a vertical sectional view showing a second embodiment. In the second embodiment, the insides of the two pipe connecting portions (outflow pipe side and inflow pipe side) of the manhole body (1) are increased in thickness in the same manner as in the first embodiment so that the flat wall (2) is formed. As a structure for increasing the effective length of the cylindrical hole (3).
【０００８】[0008]
管接続部分の側壁の厚さが増すことによって、従来のものより口径の大きい継 手（４）が装着可能となる。従って、口径の大きい管の施工が容易となる。 By increasing the thickness of the side wall of the pipe connecting portion, a joint (4) having a larger diameter than the conventional one can be mounted. Therefore, it is easy to construct a pipe having a large diameter.
