となるといった問題点があった。In Japanese Patent Application Laid-Open No. Hei 2-240338, an air supply main pipe is extended in accordance with a vacuum sewer pipe, and air is communicated between the air supply main pipe and each sewage pipe, and between the air supply main pipe and each breather pipe. There is disclosed an arrangement in which a connecting pipe is provided to eliminate the need to set up a vent pipe and a breather pipe for each vacuum valve. However, in the above configuration, it is necessary to separately lay the air supply main pipe, so the construction cost is increased, and the breather pipe is in communication with the atmosphere for each sewage tank, so the vacuum valve is opened and the sewage pipe is opened. When air is sucked in for a certain period of time after sucking sewage, the vacuum pressure also affects the inside of the breather pipe, which hinders the operation of the vacuum valve controller 10.

く、その方が効率的なバックアップが計れる。In this embodiment, each of the adjacent sewage tanks with a vacuum valve V1, V2, and V3 is provided with the configuration of the conventional sewage tank with a vacuum valve shown in FIG. A configuration is added in which the breather pipes 15 are connected so as to communicate with each other via a communication pipe 20. Therefore, any one of the three breather tubes 15,
Even if the intake ports 14 of the two breather tubes 15 are closed due to mischief, etc., the remaining one breather tube 15
Atmospheric pressure is supplied to all the vacuum valve controllers 10 through the communication pipes 20 from the suction port portion 14 of the above, so that opening and closing of the vacuum valve 4 does not occur. In addition, the connecting pipe 20 is not a closed loop, but may be a closed loop, which can provide more efficient backup.

The difference from the embodiment of FIG. 1 lies in the configuration in which three breather tubes 15 are represented by one breather tube 15. That is, V
The communication port 13 from the vacuum valve controller 10 of the sewage tank with a vacuum valve of 1, V2, V3 is connected to a connecting pipe 20, and the connecting pipe 20 is connected to the breather pipe 15 of the sewage tank with a V2 vacuum valve. . The supply of the atmospheric pressure to the vacuum valve controller 10 of the sewage basin with a vacuum valve of V1 and V3 is performed from the breather pipe 15 of the sewage basin of the V2 with a vacuum valve via a communication pipe 20. Therefore, the breather pipe 15 does not have to be erected on the ground for each of the sewage with a vacuum valve V1, V2, and V3. Therefore, a place where there is little risk of damage by a car or the like and a place that does not impair the surrounding scenery are selected. The breather pipe 15 can be erected on the ground. Note that, even in this case, the communication pipe 20 may be a closed loop.

例の効果を発揮しうるものである。FIG. 3 shows a main part of the third embodiment, which differs from the embodiment of FIG. 2 in that the breather tube 15 is housed in a box 30. The box body 30 may have a ventilation hole that can supply the atmospheric pressure to the intake port 14 of the breather pipe 15, and the material and the shape are not limited. According to such a configuration, not only can the breather pipe 15 be protected from mischief, etc., but also the effect of the second embodiment can be exerted without the possibility of the intake port 14 being blocked.

を選択してブリーザ管を立設することが可能となる。According to the present invention, the sewage system with a vacuum valve has the following excellent effects. Since the communication pipe that communicates the plurality of breather pipes is provided, even if the intake port of one breather pipe is closed due to mischief or the like, the other breather pipe that communicates with the breather pipe via the communication pipe is provided. Atmospheric pressure is supplied from the intake port, and normal operation of the vacuum valve can be ensured. Therefore, when the intake port of the breather pipe is closed, the degree of vacuum of the vacuum sewer pipe is reduced without closing the vacuum valve in the open state, and the operating efficiency of the vacuum pump is deteriorated, or the vacuum valve is closed. There is no problem that the sewage in the sewage spill overflows because it does not open as it is. In addition, since there is a communication pipe that communicates with multiple breather pipes, atmospheric pressure can be supplied to each vacuum valve controller without setting up a breather pipe on the ground for each vacuum valve as in the past. As a result, restrictions on the installation location of the breather pipe and problems with the landscape are reduced. That is, the breather pipe can be erected by selecting a place where there is little danger of being damaged by a car or the like and a place where the surrounding scenery is not impaired.
