Therefore, when the wastewater flows into the drainage branch pipe connection port 12 which is one inflow port in a full flow, the air in the closed assembly 4 is extruded to the drainage main pipe connection port 11 together with the drainage, There is a risk of forming pressure, and the device trap (not shown) that is connected to the other drainage branch pipe connection port 12 will be easily ruptured, and if it is ruptured, the sewage odor will flow back indoors and enter. Because of this, the window 21 which is the return port
The air in the assembly 4 circulates as indicated by the arrow C in the figure, and the air pressure is adjusted in combination with the original air accumulator function of the assembly 4.

That is, in FIG. 1, the main drain pipe 5 is
Is a non-buried pipe on the moisture-proof concrete 3 with a fixed support metal fitting 22, and the downstream side is drained to the outside (GL) through an S-shaped pipe 23 which is a substantially S-shape. 24
It is connected to the inlet side of.

This S-shaped pipe 23 has three elbows 29,
By using 29 ..., a so-called staircase connection of two steps (which means a pipe line in which a plurality of lower stairs are combined on the downstream side) is made from the concrete surface under the floor to the inspection cylinder 27 buried under the residential ground GL.

By the way, according to the observations made by the present inventors, it was found that, in this staircase connection, the inflow side of the elbow 29A of the first upstream stage was likely to be temporarily filled with water.
It has been found that, regardless of the presence or absence of the trap 26, the upstream instrument trap tends to be ruptured similarly to the double trap.

That is, in general, solid substances other than mere drainage are made to flow through the miscellaneous drainage pipe, so that the direction of the miscellaneous drainage pipe is set to 9
In the case of 0 ° conversion, the solid matter cannot turn a little, and its radius of curvature needs to be increased. If a so-called short elbow (which is not a large bend elbow) is used there, turbulent flow also occurs and pipe clogging occurs. It is said that a large positive pressure is generated on the upstream side.

However, in order to join the stairs of the S-shaped pipe 23, this short elbow has to be used because of the space and the place of installation, and as a result, the inlet side of the S-shaped pipe 23 is momentarily joined. It is thought that there is a possibility of full water.

【0056】勿論,このS字配管23には、管路勾配が

In particular, the main drainage pipe (5) is mainly a header.
In the case of a mold joint, when a full flow from one drain branch pipe (6) flows into the drain main pipe (5) having a larger diameter than this drain branch pipe (6), the drain branch pipe (6) located downstream of the drain branch pipe (6) ) Merges with this, and eventually, although the diameter is larger than that of the drain branch pipe (6), a full state may occur at the outlet side of the main drain pipe (5), that is, at the inlet side of the S-shaped pipe 23.

Therefore, in the above-mentioned drainage underfloor piping facility 1, the gathering unit 4 functions as an air accumulator and also as a function of the air recirculation by the window 21 of the central shaft 19 to prevent the instrument trap from being unsealed. Although it can be prevented, as a fail-safe mechanism for further avoiding a double trap by the U trap 26 and various instrument traps, the instrument trap of the miscellaneous waste instrument with a small amount of water used is omitted from the plurality of miscellaneous instruments. And also for ventilation, that is, also for ventilation pipe,
By avoiding the double trap, the noise caused by the positive pressure of the air in the pipeline due to this, the extension of the drainage time due to the disturbance of drainage, the clogging of the pipe, and the breaking of the rest of the instrument trap are prevented. I was able to do it.

It should be noted that the standard for selecting the miscellaneous drainage device omitting the device trap may be a washbasin, for example, because it uses less water, but the room is independent and is installed in a well-ventilated place. The device trap may be omitted, and since the toilet odor and the sewage odor are completely blocked by the U trap 26, the device trap may be omitted in two places.

According to the present invention, the fail-safe mechanism is provided as a double trap measure, especially a deodorant measure, which is a difficulty of the underfloor piping facility for drainage. Therefore, the quality for enhancing reliability can be further improved. That is, it is possible to prevent the instrument trap connected to the underfloor pipe from being broken.
