Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a drainage device for discharging wastewater from each household from a drainage pipe to a main drainage pipe buried underground.

[Background technology]

Conventionally, when draining wastewater from the kitchen of each home to the main drainage pipe buried underground,
A drain pipe connected to a sink or the like is connected to a drainage basin, and the wastewater is discharged from the drainage basin to a main drainage pipe underground.

However, as shown in Figure 1, if the installation area between the building 17 and the fence 18 is wide, the drainage basin 1
9 can be used, but as shown in Figure 2, the drainage basin 19 cannot be used in places where the installation space is narrow. was a commonly used method. If a trap was to be attached to the drain pipe 9, it would be difficult to install it because the installation space would be narrow, and even if it were installed, it would be impossible to clean the filth that had accumulated inside the trap.

[Purpose of invention]

The present invention has been developed in view of the above points, and allows the trap to be installed without any problem even in a narrow space between a building and a fence, and the inside of the trap can be easily cleaned. The purpose of this invention is to provide a drainage system.

[Disclosure of invention]

That is, in the drainage system of the present invention, a connecting pipe 2 is connected to a main drainage pipe 1 buried underground, an upper end opening 3 of the connecting pipe 2 is opened to the ground, and an outflow pipe section 4 having an open upper end is connected to the connecting pipe. 2, the connecting pipe 2 and the outflow pipe part 4 are integrally formed, and the inflow pipe part 5 is connected to the outside of the connecting pipe 2 from the outflow pipe part 4, and the tip of the inflow pipe part 5 is directed upward. The extended extension pipe 6 is connected to form a trap 7 with the outflow pipe section 4, the inflow pipe section 5, and the extension pipe 6, and a drain pipe is connected to the extension pipe 6 of the trap 7 via an elbow 8. 9 are connected to each other, and the opening of the outflow pipe part 4 of the trap 7 is opened upward in the connecting pipe 2 so that cleaning can be performed from the opening 3 of the connecting pipe 2. Main drainage pipe 1 buried between building 17 and wall 18
By arranging the trap 7 at an upper position parallel to the main drainage pipe 1, the trap 7 can be buried even in a narrow place, thereby achieving the above object.

The present invention will be explained in detail below with reference to Examples. As shown in Figures 3 and 4, the foundation of the building 17 and the fence 18
A main drainage pipe 1 is buried between the base and the foundation. A vertical pipe 11 is connected to the upper connecting part 10 of the connecting pipe 2, and a lower connecting part 12 of the connecting pipe 2 is connected to the vertical pipe 11.
A socket 13 is connected to the drain pipe 1, and the connecting pipe 2 is connected to the main drain pipe 1 at a cheese 14 via the socket 13. The connecting pipe 2 is connected to the main drainage pipe 1 in the vertical direction, and the upper end opening 3 of the connecting pipe 2
is open to the ground. The trap 7 is formed of an outflow pipe section 4 whose upper end is open, an inflow pipe section 5 that is integrally led out from the outflow pipe section 4, and an extension pipe 6 that is connected to the inflow pipe section 5. The outflow pipe part 4 of the trap 7 is disposed within the connecting pipe 2 and is formed integrally with the connecting pipe 2, and the inflow pipe part 5 is provided to protrude outward from the connecting pipe 2. Further, the tip opening of the extension tube 6 of the trap 7 is opened upward. A drain pipe 9 led from each household is connected to this extension pipe 6 through an elbow 8 bent at 90 degrees. Wastewater W such as kitchen wastewater and laundry wastewater from each household is collected in the trap 7 from this drain pipe 9, and then flows down from the outflow pipe part 4 of the trap 7 into the connecting pipe 2, and is then flowed down the main drain pipe 1. It is discharged to. To prevent the circulation of air between the drain pipe 9 and the main drain pipe 1 because the waste water W accumulates in the trap 7, and to prevent bad odors from flowing back into the home from the main drain pipe 1 side through the inside of the drain pipe 9. At the same time, the filth in the waste water W is precipitated and collected in the trap 7.
In the figure, 15 is a cap that closes the upper end opening of the vertical tube 11.

Therefore, when connecting the connecting pipe 2 to the main drainage pipe 1 buried underground, the inflow pipe part 5 of the trap 7 that integrally projects laterally from the connecting pipe 2 is arranged parallel to the main drainage pipe 1. Connect and rotate the connecting pipe 2 or socket 13 to the drain main pipe 1 by adjusting the rotation in the horizontal direction so that the connecting pipe 2 or the socket 13 is installed. Next, the inflow pipe section 5 of the trap 7
Connect the extension pipe 6 to the elbow 8 and connect the extension pipe 6 to the extension pipe 6.
The elbow 8 is connected to the drain pipe 9 from each household. Here, since the tip of the extension pipe 6 faces vertically upward and the elbow 8 is rotatably connected to the extension pipe 6, the elbow 8 can be freely rotated in the horizontal direction. For example, as shown in FIG. 3, the elbow 8 can be connected to the drain pipe 9 in a direction perpendicular to the main drain pipe 1. In addition, the vertical height of each connection part 10,
The adjustment is made by adjusting the connection position of 12. By arranging the trap 7, elbow 8, etc. parallel to the main drainage pipe 1 in this way, there is no need to bury them, and the trap 7 can be installed even in places where the installation area between the building 17 and the fence 18 is narrow. can be attached to the connecting pipe 2. Now, the filth in the waste water W flushed from the home settles and accumulates in the trap 7, but the outflow pipe part 4 of the trap 7 is arranged inside the connecting pipe 2, and the opening of the outflow pipe part 4 is Since it faces upward, the cleaning tool inserted from the opening 3 of the connecting pipe 2 can be smoothly inserted into the opening of the outflow pipe 4, and the trap 7 can be easily inserted.
This allows you to clean the inside. Of course, the inside of the main drain pipe 1 can also be cleaned by inserting a cleaning tool through the opening 3 of the vertical pipe 11.

In addition, in FIG. 6, an inclined surface 20 is formed on the connecting pipe 2 above the outflow pipe portion 4 in order to widen the opening area of the connecting pipe 2. In addition, in the above embodiment, the upper and lower widths of the connecting portion 12 of the connecting pipe 2 and the cheese 1
Due to the vertical width of the connection part 16 of 4 and the vertical height of the trap 7, the buried position of the drain pipe 9 is the main drain pipe 1.
However, Figures 7 to 14 show that the drain pipe 9 can be trapped without any problem even at construction sites where the distance between the main drain pipe 1 and the drain pipe 9 is narrow. A cheese 14 is used as the connecting pipe 2 so that it can be connected to the main drainage pipe 1 via the pipe 7. In the embodiment shown in FIGS. 7 to 12, the inflow pipe portion 5 of the trap 7 is extended obliquely upward from the outside of the cheese 14, and the extension pipe 6 bent at 45 degrees is connected to the inflow pipe portion 5. The trap 7, which is bent into a substantially V-shape, collects the waste water W to prevent the backflow of bad odors, and also allows the filth in the waste water W to settle and be removed within the trap 7. In particular, in this trap 7 as well, since the opening of the outflow pipe section 4 faces the opening 3 side of the connecting pipe 2 within the cheese 14, cleaning tools can be easily inserted and the inside of the trap 7 can be cleaned easily. It is something. Further, the filth in the main drain pipe 1 will not enter the outflow pipe section 4 of the trap 7. Furthermore, in the case shown in FIG.
12 has a branch pipe 21 extending from the side of the cheese 14 in a direction orthogonal to the main drainage pipe 1. Furthermore, in the case shown in FIGS. 13 and 14, the cheese 14 is bent at 90 degrees and the main drain pipes 1 and
It is designed so that it can be connected when the two are orthogonal, and is used to bury it in the corner of a building.

[Effect of idea]

As mentioned above, the present invention connects the connecting pipe to the main drainage pipe, forms the connecting pipe and the outflow pipe part of the trap integrally, and connects the inflow pipe part from the outflow pipe part to the outside of the connecting pipe. An extension pipe whose tip extends upward is connected to the pipe section, and a drainage pipe is connected to this extension pipe of the trap via an elbow, so that drainage buried between the building and the building wall can be removed. Traps and elbows can be buried above the main pipe, eliminating the need for burying space for traps and elbows, allowing traps to be installed without any problems even in narrow spaces between buildings and walls. In addition, the opening of the connecting pipe is opened to the ground, and the outflow pipe part of the trap with an open upper end is placed inside the connecting pipe, so that the connecting pipe and the outflow pipe part are integrally formed. A cleaning tool can be inserted into the trap through the opening of the outflow pipe section, making it extremely easy to clean the inside of the trap.
