2. Description of the Related Art Generally, public sewers are often laid after an urban area is formed. In such a case, the miscellaneous drainage in the house, which had been drained into the conventional U-shaped gutter at the time of laying the public sewerage, was temporarily spilled to the newly installed public manhole so as not to hinder the immediate use. I have.

On the other hand, when a public sewer system is provided in advance (see, for example, Japanese Utility Model Publication No. 6-3903), the entire sewer system does not function unless a corresponding drainage system is installed in the house. Therefore, legal regulations have been made on the promotion of installation of drainage facilities on residential land.

[0004] In any case, plugs and caps are temporarily covered with the public manhole for the purpose of advanced pipe installation after the installation (hereinafter referred to as advanced pipe installation). It is being buried so that it can be excavated again. Therefore, even a sewage sewage made of public PVC is constructed into a sewage sewage using a multi-way fitting, and this is covered with a temporary plug, a receiving plug, for example, straight piping, right or left piping, It is buried so that various kinds of advanced pipes such as right or left merging pipe, left and right merging pipe, or three-way merging pipe can be laid.

[0005] By the way, as shown in Japanese Utility Model Laid-Open No. 59-107676 and Japanese Utility Model Laid-Open No. 53-90221, an inlet plug used for a PVC sewage basin is disclosed.
A head with a flange, a receptacle insertion part, and a tip surface having a smoothly continuous surface on the inner peripheral surface of the main body. The socket plug is pushed in and inserted. Therefore, no dead space or filth pool is formed at the front end face of the socket plug.

By the way, such a manhole or a sewage basin is placed at a predetermined excavated position, and a check tube is erected in accordance with the surface height of the manhole or sewage. In order to improve the reliability of pipe laying, when the check tube is bonded and bonded to the check tube hole during such work, Unlike conventional small-diameter masques, large amounts of adhesive liquid have tended to be applied to the slightly enlarged bore of the inspection cylinder mouth, so a specific part of the inspection cylinder mouth has been used. Adhesive liquid increases.

[0008] Therefore, the adhesive liquid dripping from the inspection port is dripped on the tip end face of the receiving plug of the lower inflow side receiving port, or penetrates into the receiving port insertion portion and solidifies. Therefore, after that, even if you try to extract this receiving plug for advanced pipe laying, it will not be possible to extract it, and it will not be possible for humans to construct a small-diameter inspection tube, and in the worst case,
The problem of causing redoing of pipe laying has come to occur.
