The casing 5 is provided with a plurality of vertically extending reinforcing ribs 8 on the outer surface of the four side walls.
A miscellaneous drainage inlet 9 is formed on the front surface, and a miscellaneous drainage outlet 10 is formed on the rear portion. The miscellaneous drainage inlet 9 and the miscellaneous drainage outlet 10 have substantially the same diameter and are formed at an intermediate height between the front and rear surfaces. The opening formed above the casing has a large diameter, and the stepped portion 1 on the inner surface portion is formed.
A cover 7 for covering the opening 6 is detachably attached to 1. The lid 7 is formed in a rectangular shape so as to fit into the peripheral portion of the opening 6, and the upper surface 7 a of the lid 7 has a plate-shaped knob 12 formed at the center thereof for opening and closing operation.
Two holes 3 are formed at the bottom of each of the recesses 13, and a water passage hole is formed in the bottom of each recess 13 to allow rainwater accumulated therein to flow into the casing 5. A pressure regulating vent 15 is formed on one side of the lid 7 to release the pressure in the casing 5 when the pressure fluctuates (see FIGS. 1 and 2).

The trap mechanism 4 incorporated inside the casing 5 is provided with a groove-shaped guide 16 provided on the left and right side wall portions of the casing 5 on the side of the miscellaneous drainage outlet 10, and is guided by the guide 16. It is composed of a partition member 17 that can be inserted and removed vertically, a basket-shaped water-permeable container 18 that is installed so as to be able to be taken in and out on the side of the wastewater inlet 9, and a triple intrusion prevention means of a flap 19 that opens and closes the wastewater inlet 9. Have been. The partition member 17 has left and right portions 17a, 17a.
Is formed in a plate-like shape so as to be slidably fitted to the guide 16, the center portion is expanded toward the gray water inlet 9, the cross section is formed in a plan view in “Ω” shape, and the upper surface portion is substantially horizontal. The formed top plate 20 is integrally formed, and a water passage 21 is formed vertically at a portion facing the miscellaneous drainage outlet 10.

The lower end 17b of the partition member 17 is
When the partition member 17 is mounted on the guide 16, it is immersed in the drainage 22 stored between the lower end of the circular drainage outlet 10 and the bottom 3 of the casing 5, and is lower than the upper end of the water-permeable container 18. The space inside the casing 5 is partitioned by the partition member 17 into a drainage outlet 9 side and a drainage inlet 9 side, where a so-called "water seal" is formed. The water passage container 18 is formed in a cage shape having a large number of thin slits 23 provided in four side walls, and a flange portion 1 having an upper end opening portion opened to the side.
8a, the upper end of the flange 18a of the water container 18 when the water container 18 is installed in the casing 5 is lower than the lower end of the gray water inlet 9. It is located below.

Further, the flap 1 for opening and closing the gray water inlet 9 is provided.
Numeral 9 is formed in a disk shape having a diameter slightly larger than the diameter of the gray water inlet 9, and the upper end thereof is rotatably supported by a hinge 25 near the upper end of the gray water inlet 9. Together with the side wall portion 2 of the casing 5 which is inclined so as to have a small diameter on the third side, the gutter drainage inlet 9 is closed by the weight of the flap 19.

The procedure for using the sewage chamber yard 1 formed as described above will now be described. First, the trap mechanism 4 is set in the casing 5 of the sewage chamber yard 1, and the opening 6 is closed by the lid 7. Next, as shown in FIG. 4, a drainage channel (branch pipe) 29 from a drainage port 28 of a sink 27 installed in a kitchen 26 indoors 25 to a sewage main pipe (not shown).
The casing 5 is buried underground with the lid 7 exposed on the ground. Then, the gray drainage inlet 9 is connected to the drainage channel 29 on the drainage port 28 side, and the graywater drainage outlet 10 is connected to the drainage channel 29 on the sewage main pipe side.

In the sewage chamber basin 1 installed as described above, the drainage discharged from the drain 28 of the sink 27 pushes open the flap 19 covering the miscellaneous drainage inlet 9 with the force of the drainage, and the basket is opened from here. The water flows into the water passage container 18 having the shape of a circle. The waste water that has flowed into the water passage container 18 has a large number of narrow slits 23, 23,. Strained,
Moisture flows out to the miscellaneous drain outlet 10 side. The wastewater that has flowed out to the gray water outlet 10 in this way flows into the main pipe from the gray water outlet 10 through the drainage channel 29, and thus the wastewater that has flowed into the main pipe contains almost no solid lump. The clogging of the drainage channel 29 and the main pipe due to this is prevented.

Since the internal space of the casing 5 is partitioned by a so-called “water seal” by the partition member 17, the odor filling the sewage main pipe passes through the miscellaneous drainage outlet 10 through the miscellaneous drainage inlet in the casing 5. 9 is prevented from flowing. Further, even if small animals such as rats and cockroaches that inhabit or breed in the sewage main line try to enter the casing 5 from the drainage outlet 10 and to the drainage inlet 9 side from here, the “water seal” formed by the partition member 17 is formed. ,
The trapping mechanism 4 comprising triple intrusion prevention means for the flap 19 covering the side wall portion of the water passage container 18 and the miscellaneous drainage inlet 9 reliably prevents the intrusion. That is, most of the small animals such as rats and cockroaches are prevented from entering at the “water seal” portion. Since the portion is located, it cannot pass therethrough, and entry into the water passage container 18 is prevented.

Further, even if a small animal such as a rat or a cockroach intrudes into the water passage container 18 by some means, the flap 19 closing the miscellaneous drainage inlet 9 prevents the ingress into the miscellaneous drainage inlet 9. . Thus, the processing of the solid lump such as cutting chips at the time of cooking separated from the waste water and captured in the water passage container 18 is performed by lifting the lid 7 and opening the casing 6 with the opening 6.
, And insert the hand from here to take out the water passage container 18. After that, after the solid mass such as the swarf that has been captured is scraped out and treated as garbage, the water passage container 18 is mounted in the casing 5 again, and the opening 6 is closed with the lid 7 to complete. You do it.

In the above embodiment, a "water seal" formed in the casing 5 by the lower end portion 17b of the partition member 17 and the drainage immersed in the lower end portion 17b, the side wall portion 2 of the water passage container 18, the miscellaneous drainage inlet 9 Although the trap mechanism 4 is formed by the triple intrusion prevention means of the flap 19 covering the flap 19, even if each of these triple intrusion prevention means is formed independently, it is possible to sufficiently exhibit the intrusion prevention effect. As a matter of course, for example, as shown in FIG.
It is needless to say that the "water seal" formed by the above can be provided at each of the wastewater inlet 9 and the wastewater outlet 10. Further, in the above-described embodiment, the sewage chamber basin 1 is installed and used in the drainage channel 29 between the drainage port 28 of the sink 27 and the sewage main pipe, but in the drainage channel from the bathroom. Needless to say, it can be provided or provided in a toilet drainage channel (both not shown).
