いる。2. Description of the Related Art As is well known, it is known that double traps should be prohibited in pipe laying work, especially in home piping work. For example, traps must not be provided continuously, appliance traps (for sanitary appliances directly connected to drains,
In principle, each trap is provided, but the trap must not be connected to a drain having a trap (which is called an instrument trap), and drainage from the toilet must not be allowed to flow into the trap. Have been.

す。[0003] Such a double trap will be described by way of example. In FIG. 11, reference numeral 1 denotes a building, on which an instrument trap 2 is provided. When the trap tube 4 is interposed between the appliance trap 2 and the house drain pipe 3, the branch pipe 5 located therebetween is sealed or closed, forming a double trap. In the drawing, reference numeral 6 denotes an inspection cylinder of the trap 4 and reference numeral 7 denotes a 90 ° elbow provided at the trap inlet.

る、等の不都合が生じる。As shown in this example, although a trap is provided on the upstream side, a trap is provided on the downstream side, and when the two traps are completely sealed, the trap on the upstream side and the trap on the downstream side are provided. The drainage pipe system sandwiched between the pipes becomes closed, that is, forms a double trap, and as a result, it becomes difficult to move air in the pipes. And the air in the pipe is compressed by the pressure of the influent water, generating noise,
Inconveniences such as foaming, and further, the flow of the drainage are disturbed, the drainage time is prolonged, and the pipe may be clogged.

する。When a double trap is formed in the drainage pipe system connected to the branch pipe flow path 14 when the pipe is laid, the partition plate 15 is removed and embedded. If it is found that a double trap is to be formed in the drainage pipe system after the in-house piping work, the partition plate 15 is attached to the inspection tube 6.
To remove the water sealing section 16 to avoid a double trap.

ない会所ますにすることができる。Therefore, in the sewage tank with a partition plate of the present embodiment, the water sealing portion 16 can be formed and the double trap can be avoided only by attaching and detaching the partition plate 15, which is extremely convenient and can be easily performed. Improve the reliability of laying work. Of course, the main body 10 is used with and without a trap, and is mass-produced and inexpensive. Then, if the main body 10 without the partition plate 15 is used, the main channel 13
The drainage of the pipe can be prevented from flowing back to the branch pipe by the upward L-shaped branch pipe flow path 14.
【0016】また、仕切板15によって封水部16を形

できるので、管布設工事のやり直しをする必要がない。According to the present invention, since the water sealing portion is formed by the detachable partition plate and the branch pipe flow path, the double trap is formed when forming the double trap or after the pipe laying work. When it becomes clear, the water sealing section can be released immediately, which is extremely convenient and improves the reliability of pipe laying work. In addition, since the partition plate can be moved in and out of the inspection tube, there is no need to perform pipe laying work again.
