に点検筒７がＴＳ接合されて立設している。In FIG. 2, upper and downstream ports 3, 3 are provided on a main shaft a of the main body 1, and the main flow pipe 2 buried in the residential land is connected to these ports 3 by TS. Joining (T
and a sub-shaft b inclined 45 ° to the upstream side with respect to the main shaft a. The distribution pipe receiving port 4 is connected to a horizontal distribution pipe 5 via an increaser (not shown). In addition, the main body 1 is provided with a small-diameter inspection tube receptacle 6 on the ground surface side orthogonal to the main shaft a, and the inspection tube 7 is TS-joined to this and stands upright.

事は難航する、という苦情があった。In the meantime, in such a Y-shaped small-diameter trough, the branch pipe 5 is contracted to a minimum between the main flow pipe 2 and the vertical pipe 9 so that the branch pipe receiving port 4 and the first elbow 8 receiving port are directly connected. Even if they are joined, the gap d remains because of the Y-shape, so that the advantage of being able to be constructed with the same excavation width as the pipeline, which is one of the features of the small-diameter masquerade, cannot be fully demonstrated. 2
As shown in (1), TS bonding in a very narrow land where the building 11 is close (work of wiping the inlet and outlet sufficiently, applying an adhesive, immediately inserting and bonding, and leaving it to stand for 10 to 30 seconds) There was a complain that construction was difficult.

When the joined increaser 14 is pushed in, the socket 1
3 is slightly enlarged in diameter, so that the ring-shaped protrusion 22 can be fitted into the fitting groove 17. Next, the vertical part of the bend pipe 15 is made vertical, and the vertical pipe 9 is connected. As a result, the drainage on the floor can be joined to the main flow pipe 2. Accordingly, since the main body 1 and the bend pipe 15 do not perform the TS joining work in a narrow place, the entire construction can be easily performed.

ことができる。According to the present invention, the spigot of the L-shaped bend pipe is rotated on the side wall of the main body, on the socket socket extending horizontally and perpendicularly to the main axis of the main body. Since the connection is made possible and prevented from coming off in the axial direction, the shortest distance is formed orthogonally, and the socket for the receiving port is hidden under the large-diameter inspection tube. This makes it possible to make the distance between the inspection tube and the vertical pipe as small as possible, and furthermore, it is possible to install the inspection tube on a very small ground. Needless to say, the number of parts can be reduced, and the cost is reduced together with the work in which the number of work steps is reduced. Moreover, the upper and downstream connection parts and the connection part of the vertical pipe are vertically separated, and
The inflow side pipe end face of the vertical portion of the L-shaped bend pipe becomes horizontal,
At the same time, the connection work with the vertical pipe becomes easy, which is convenient for very narrow land. In addition, if the vertical portion of the L-shaped bend tube is laid as it is, it can be used in a parallel space for extremely narrow ground.
