Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a drainage basin used at the connection part of a main drainage pipe buried underground along a building.

[Background Art] Generally, a main drainage pipe through which wastewater flows is buried underground along the outer wall of a building, and a drainage basin for cleaning is connected to an appropriate location of the main drainage pipe. By the way, as shown in FIG. 4, if an obstacle 4 protrudes from the outer wall of building A, connect a flexible joint 5 to the drainage basin 6 as shown in FIG. 5, a plurality of drainage main pipes 2 are connected in such a way as to avoid obstacles 4. However, after burying the main drainage pipe 2,
Check if it is connected properly or
In order to check whether the main drainage pipe 2 is buried or not, a mirror 7 is inserted into the drainage basin 6 as shown in Fig. 5, but if the bent joint 5 is used as shown above, Because it is not possible to see inside the main drainage pipe 2, the inspection may fail, or it may be necessary to add and connect another drainage basin 6. Many drainage basins at 4 obstacles 6
However, there was a problem in that the workability was also poor.

[Purpose of the invention] The present invention was made in view of the above points, and the purpose is to provide a drainage basin that allows accurate inspection of the inside of the main drainage pipe and is easy to construct. .

[Disclosure of the invention] That is, the drainage basin of the present invention has connecting pipes 3, 3 connected to the main drainage pipe 2 protruding outward from both sides of the lower part of the main body 1, and the axes of the connecting pipes 3 being parallel and parallel to each other. It is made by shifting left and right, and the main body 1
By shifting the axial center of the connecting pipe 3 provided in the left and right directions, the bent joint 5 is made unnecessary and the above object is achieved.

The present invention will be described in detail below based on illustrated embodiments. As shown in Figs. 1 and 2, connecting pipes 3,
3 protrude so as to face in opposite directions.
The protruding directions of both the connecting tubes 3, 3 are parallel, and the axes of the connecting tubes 3, 3 are provided at positions shifted from side to side within a horizontal plane. That is, the slopes of both the connecting pipes 3, 3 are eliminated, and they are rotationally symmetrical in the horizontal plane of the main body 1.

Therefore, when connecting the main drainage pipe 2 to the four obstructions in the building A using the drainage basin B formed as described above, it is necessary to avoid the obstructions as shown in Figures 2 and 3. A drainage basin B is buried near the obstacle 4 to avoid objects 4, and the main drainage pipe 2 is connected to each connecting pipe 3 of the drainage basin B. Since the connecting pipes 3, 3 of the drainage basin B are offset from each other to the left and right in the horizontal plane, the main drainage pipe 2 is connected with an offset amount of L of the axis of each connecting pipe 3, 3. The main drainage pipe 2 can be connected so as to avoid obstacles 4 due to the displacement. The pipe line 9 that is continuous with both connecting pipes 3 and 3 in drainage basin B meanders from one connecting pipe 3 to the other connecting pipe 3, as shown in Figure 1, and drainage etc. can clog inside drainage basin B. It's nothing like that. Moreover, since the drainage basin B is formed rotationally symmetrically, by rotating the drainage basin B, it can be used for both left and right purposes. Now, to check whether the main drain pipe 2 is properly connected, insert the mirror 7 into the drain B as shown in Figure 5 and inspect it. The connecting pipe 3 of the drainage basin B and the connecting pipe 3 of the adjacent drainage basin 6 will be arranged in a straight line as shown in Fig. 2, so if you insert the mirror 7 into the opening of the connecting pipe 3 of this drainage basin B. The opening of the connecting pipe 3 of the adjacent drainage basin 6 can be definitely seen, and the inside of the main drainage pipe 2 can be inspected without failing the inspection. 8 in Figure 3 is a public sewage basin, and when connecting the main drainage pipe 2 to this square 8, use the above drainage basin B to return the arrangement of the main drainage pipe 2 to the original line of the main drainage pipe 2. It can be connected to the sewage basin 8 without having to do so.

In addition, in the above embodiment, the slope of both connecting pipes 3, 3 is eliminated, but it is also possible to provide a slope to both connecting pipes 3, 3, and by doing so, the waste water will flow smoothly. .

[Effects of the invention] As described above, in this invention, connecting pipes connecting to the main drainage pipe are protruded outward from both sides of the lower part of the main body, and the axes of the connecting pipes are parallel and shifted from side to side. The main drainage pipes connected to the connecting pipes can be buried offset to the left and right, and even if there are obstacles on the outer wall of the building, the main drainage pipes can be connected without using flexible joints like in the past. Since there are no bent parts, it will not fail the inspection, and the inside of the main drainage pipe can also be inspected. Moreover, only two drainage basins need to be buried, compared to the conventional four.
It is possible to improve workability and reduce the number of uses, thereby reducing construction costs.
