いる。A semi-cylindrical hanging wall 56 having a diameter smaller than that of the upper joint port portion 51 is provided inside the bulging chamber 53, and an upper edge of the hanging wall 56 is formed on an inner peripheral surface of the hanging wall 56. The drift plate 57 is provided so as to be inclined from the portion to the lower edge portion. Further, inside the taper chamber 55, a swirl straightening plate 58 having an inclined surface along the same spiral direction is provided at a position to receive the flow of the drainage that is drifted by the drift plate 57 and flows down.

Since the deflector plate 57 was provided,
The gap (solids passage gap) between the drift plate 57 and the inner peripheral edge of the lower end of the upper joint port portion 51 is narrow, so that the test ball cannot pass through the solids passage gap and cannot enter the bulging chamber 53. , The passage was not smooth.
That is, the conventional piping member 50 could not be said to satisfy the above requirements.

Further, as shown in FIG. 4, a portion where the horizontal joint opening 10 is not provided is locally reduced in diameter, and the deflector plate 14 is provided by utilizing the inner wall portion 12 of the reduced diameter portion. There is.
The deflector plate 14 is located between two lateral joint ports 10 that are positioned opposite to each other with the bulging chamber 3 in between, and the side close to one of them (the right side in FIG. 2) is close to the upper end and the other. It is provided so that the side (the left side) is the lower end. Further, as shown in FIG. 4, it is provided so as to have a downward slope in a direction projecting from the inner wall portion 12.

In one of the orientation limiting pieces 18, the drainage flow that collides with the deflector plate 14 and is about to be scattered in the horizontal direction is introduced into the lateral joint opening 10 (right side in FIG. 3) adjacent to the upper end of the deflector plate 14. The other directivity limiting piece 19 prevents the scattered drainage flow from adjoining the lower end of the drift plate 14 at the horizontal joint port 10 (left side in FIG. 3).
It prevents it from flowing in. By doing so, it is possible to prevent the drainage flow from the upper joint port 6 from flowing back from the lateral joint port 10 to the lateral branch pipe 8, and the equipment (toilet bowl) to which the lateral branch pipe 8 is connected. , A sink, various traps, etc.) can be prevented from causing an offensive odor or fouling of the device.

(See FIGS. 2 and 4), not only is it difficult for the solid matter to be caught on them, but also the deflector plate 14 is guarded so that the solid matter is not caught or clogged. In this embodiment, in addition to the directivity limiting pieces 18 and 19, a horseshoe-shaped inner rib 20 inside the lateral joint opening portion 10 is provided.
(See FIG. 5) is provided to prevent the inflow of wastewater into the lateral branch pipe.

ようになっている。At the upper edge 3a of the bulging chamber 3, as shown in FIGS. 2 and 4, a draining edge portion 21 having a downward edge is provided along the opening edge portion excluding the region where the inner wall portion 12 is formed. It is provided. Therefore, also by this, the drainage flow is prevented from being caught in the lateral joint opening 10. Inside the taper chamber 4, as shown in FIG. 1, a swirl straightening plate 23 having a large blade area and small swirl straightening plates 24, 25 are provided.
It is provided so as to incline along the same spiral direction. Therefore, a swirl flow along the inner peripheral surface of the bulging chamber 3 or the inner peripheral surface of the taper chamber 4 is induced in the drainage flow that has been directed obliquely downward by colliding with the deflector plate 14, An air core is formed on the side of the drainage pipe 2 so that the flow-down obstacle does not occur.

Since it becomes possible to provide the lateral joint opening 10 also on the side surface (upper side in FIG. 3) which is the back side of 6), the lateral joint opening 10
Four can be provided around the expansion chamber 3.
Of course, the number of the horizontal joint ports 10 may be one or two.
