It has a tube 3. Each vertical drain pipe 3 is formed by connecting a plurality of vertical pipes 4 vertically vertically by a joint pipe 5, and the branch pipe 2 is connected to the joint pipe 5;
By connecting the ventilation pipe 6 to the upper end, the drain pipe itself functions as a ventilation pipe. A horizontal drain branch pipe 8 is connected to a lower end of the vertical drain pipe 3 via a bend pipe 7.

される。As shown in FIG. 4, each of the vertical drain pipes 3 is piped to an appropriate place in a building, and each horizontal drain branch pipe 8 is connected to a horizontal drain main pipe 9. One end of the horizontal drainage main pipe 9 is closed, and the other end is connected to a meeting place yard 10 communicating with sewage. The horizontal drainage branch pipe 8 and the horizontal drainage main pipe 9 are slanted so as to go downward as they go downstream, whereby drainage from each drainage device 1 flows from the vertical drainage pipe 3 through the horizontal drainage branch pipe 8. Then, they merge at the horizontal drain main pipe 9 and are discharged from the meeting place yard 10 to the sewage.

た。Conventionally, the connection between the horizontal drain branch pipe 8 and the horizontal drain main pipe 9 is as follows.
A Y-shaped joint pipe 11 as shown in FIGS. 5 and 6 or a T-shaped joint pipe was used. That is, in the illustrated example, the main pipe part 12 of the Y-shaped joint pipe 11 is a part of the horizontal drain main pipe 9, and the branch pipe part 12 of the Y-shaped joint pipe 11 is a part of the horizontal drain branch pipe 8.
（考案が解決しようとする課題） 横排水枝管８や横排水主管９の傾斜勾配は、配管スペ
ースの制約があるため、一般に管径（mm）の逆数を目安

の流れは比較的緩やかである。(Problem to be solved by the invention) The inclination of the horizontal drain branch pipe 8 and the horizontal drain main pipe 9 is generally determined using the reciprocal of the pipe diameter (mm) as a guide because there is a restriction on the piping space. 1/1 for horizontal drainage branch pipe
The gradient is 25, and the horizontal drain main pipe with an inner diameter of 150 mm has a gradient of 1/150, usually a small gradient in the range of 1/100 to 1/120. Therefore, the flow of drainage in the horizontal drain main pipe 9 and the horizontal drain branch pipe 8 is relatively gentle.

いった問題が生じる。In the above-mentioned drainage pipe device, when the drainage in the horizontal drainage branch pipe 8 joins the drainage flowing in the horizontal drainage main pipe 9, part of the drainage from the horizontal drainage branch pipe 8 is transferred to the horizontal drainage main pipe 9. The phenomenon of flowing backward to the upstream side occurs. Then, as shown in FIG. 8, the ventilation space 15 exists above the water surface 14 of the drainage on the downstream side of the confluence portion, but the ventilation air 15 becomes very high on the upstream side of the confluence portion as shown in FIG. The pipes may become smaller, or the pipes may be completely filled with drainage and the ventilation space may be lost. When the ventilation space is eliminated or reduced in this way, the function of the drainage pipe itself as a ventilation pipe at the time of drainage flow from the drainage device 1 is hindered, and the pressure in the pipe increases, so that the drainage device 1 is sealed. There is a problem that the water trap is broken.

A horizontal drainage branch pipe 8 extending laterally from the lower end of each of the vertical drainage pipes 3 is connected to a horizontal drainage main pipe 9, and the horizontal drainage branch pipe 8 and the horizontal drainage main pipe 9 go downward as they go downstream. In the junction structure of the horizontal drain pipes in the drain pipe device which is inclined so as to be inclined, the inclination of the horizontal drain branch pipe 8 with respect to the horizontal of the connecting portion 18 with the horizontal drain main pipe 9 is as follows: And, the inclination of the horizontal drain branch pipe 8 above the connecting portion 18 with respect to the horizontal is made greater than the inclination thereof, and the connecting port 19 of the connecting portion 18 with the horizontal drain main pipe 9 is formed at the top of the horizontal drain main pipe 9. It is located on the side except for.

圧力の上昇を防止することができる。(Operation and Effect of the Invention) According to the present invention, the drainage of the lateral drainage branch pipe 8 is accelerated at the connecting portion 18, so that the momentum toward the downstream direction is large and merges with the drainage in the horizontal drainage main pipe 9. In this case, backflow to the upstream side is prevented. Further, since the connection port 19 of the connecting portion 18 with the horizontal drainage main pipe 9 is located on the side surface except for the top of the horizontal drainage main pipe 9, the ventilation space in the horizontal drainage main pipe 9 is reduced or reduced. It is possible to prevent an increase in pipe pressure during drainage.
