本考案は下水道管の途中に点検、清掃のために
設置され、小口径汚水桝として用いられる三方管
継手に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a three-way pipe joint that is installed in the middle of a sewer pipe for inspection and cleaning purposes and is used as a small-diameter sewage basin.

For example, sewage, rainwater, etc. discharged from households are collected at a community hall and then discharged into a sewer system. Conventionally, concrete kaisho-masu were used for such kaisho. However, concrete kaisho-masu is heavy and difficult to transport and install.
The volume is large, especially when discharging sewage and rainwater separately, the number of chambers increases and takes up a large space, and it is not possible to prevent water from entering from the connection between the chambers and the polyvinyl chloride piping. It has the following disadvantages. In addition, with the development of inspection and cleaning tools, large-diameter pipes are no longer needed, so recently, three-way pipe joints made of polyvinyl chloride have come to be used as joints instead of pipes.
現在用いられている会所継手を第９図および第

The currently used joints are shown in Figs. 9 and 10.

点検清掃筒となる。 What is shown in FIG. 9 is an LT type joint 1, in which sockets 11, 12, 13 are formed on three sides.
The sockets 11, 12, 13 are provided with pipes 21, 2, respectively.
2 and 23 are connected. If the sewer main pipe is buried deep in the above-mentioned joint 1, it becomes a vertical pipe and the pipe 23
is the upstream pipe, that is, the pipe that connects to the domestic drainage side,
The pipe 22 is a downstream pipe, that is, a pipe connected to the public sewer system, and the pipe 21 is an inspection and cleaning pipe, and the upper part is connected to the outside. In addition, when the main sewage pipe is buried shallowly, it becomes a horizontal pipe, the pipe 21 becomes an upstream pipe, the pipe 22 becomes a downstream pipe, and the pipe 23 becomes an inspection and cleaning tube.

22 and 23 are connected. In the case of vertical piping, the pipe 23 is the upstream pipe, the pipe 22 is the downstream pipe, and the pipe 21 is the pipe for inspection and cleaning. In the case of horizontal piping, the pipe 21 is the upstream pipe, the pipe 22 is the downstream pipe, and the pipe 23 is the pipe for inspection and cleaning. It becomes a cylinder.

In the case of vertical piping in the LT type joint 1, when attempting to inspect the upstream pipe 23 by inserting a rod with a mirror attached to the tip from the inspection/cleaning tube 21, the diameter
Only the diameter d 2 portion of the upstream pipe 23 of d 1 can be seen, and when inserting a rod or the like for cleaning, if the inspection and cleaning tube 21 is long, the rod can only be inspected and cleaned approximately vertically. The rod cannot be inserted into the tube 21, and therefore it is difficult to insert the rod into the upstream pipe 23 side. In addition, in the case of horizontal piping, it is easy to inspect the upstream and downstream piping 21, 22.
Although it is easy to clean by inserting a rod or the like into the tube 22 side, it is difficult to insert a rod or the like into the tube 21 side.

入して清掃を行うことが困難である。 In the DT type fitting 3, inspection is easy whether the piping is vertical or horizontal, but if the inspection and cleaning tube is long, a rod cannot be inserted into the inspection and cleaning tube which is positioned approximately vertically. Therefore, in the case of vertical piping, it is difficult to insert a rod or the like into the pipe 23 side to perform cleaning, and in the case of horizontal piping, it is difficult to insert a rod or the like into the pipes 21, 22 side to perform cleaning.
