[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage basin having both a normal drainage basin and a drop drainage basin.

[0002]

2. Description of the Related Art As shown in FIG. 5, an ordinary drainage basin (10)
In that case, the inlet (12) and the outlet (13) are provided on the side surface of the main body (11).
In order to make it possible to use this as a drop drainage basin, a connecting cylinder body having a hole (15) in the bottom surface (14) and a collar (16A) in the hole (15) is provided. There is provided a structure in which (16) is fitted and the outlet (13) is closed by a plug (17) (Jitsuko 62-43037).

[0003]

[Problems to be Solved by the Invention] However, in the above-mentioned conventional structure, the connecting cylinder body (16) must be prepared as a separate member, and it takes time and effort to determine the position and diameter of the hole (15). There were problems such as.

[0004]

Means for Solving the Problems As a means for solving the above conventional problems, the present invention provides a mud ring (28) having a predetermined inner diameter on a bottom surface (27), and an inner circumference of the mud wheel (28). Kangakaritome step portion (28A)
It is intended to provide a drainage basin (20) having a receiving structure formed by forming.

[0005]

[Operation] When the drainage basin (20) is used as the drop drainage basin (20A), the inner portion of the mud ring (28) on the bottom surface (27) of the drainage basin (20) is cut off to form the hole (31). Set up. And because Kangakaritome stepped portion on the inner circumference to該泥wheel (28) (28A) is formed has a socket structure, and connect the drain pipe (32) to該泥wheel (28) the The pipe locking step portion (28A) serves as a stopper for the drain pipe (32).

[0006]

[Embodiment] The present invention will be described with reference to an embodiment shown in FIGS. 1 to 4. A drainage basin (20) has a main body (21) provided with an inspection tube receiving portion (22) at an upper end thereof and a side surface thereof. Is the inlet port (23, 24, 2
5) and the outlet side receiving part (26) are provided, the bottom surface (27) is provided with a mud ring (28), and the inner periphery of the mud wheel (28) is pipe-locked The stepped portion (28A) is formed to form a receiving structure. And the body
(21) A boss (29) having a central hole (29A) is provided at the center of the inner circumference of the mud ring (28) on the bottom surface (27).

In the drainage basin (20), the outlet side receiving portion
Inner diameter of (26) (outer diameter of drain pipe connected to the receiving portion (26))
And the mud wheel (28) have the same inner diameter and are set to, for example, 150 mm, and the inner diameter of the inlet side receiving portion (23, 24, 25) is, for example, 100
is set to mm.

When using the above-mentioned drainage basin (20) as a normal drainage basin (20), the drainage basin (20) is installed on the foundation through the mud ring (28) and the inspection cylinder An inspection cylinder is connected to the receiving port (22), an inflow pipe is connected to the inflow receiving ports (23, 24, 25), and a drain pipe is connected to the outflow receiving port (26).

Drop the drainage basin (20) above the drainage basin (20A)
When using it as, for example , the tip of the center leg (30A) of the compass-shaped cutter (30) as shown in FIG.
Abut the center hole (29A) of the boss (29) at the center of the
The bottom edge (27) of the drainage basin (20) by the tip blade portion (30C) of B).
Cut off the inner part (27A) of the mud ring (28).

In this way, as shown in FIGS. 3 and 4, a hole (31) is cut in the bottom surface (27) of the drainage basin (20A), and the drainage pipe (32) is provided with a receiving portion as shown in FIG. Mudstones that act as (28)
Connected to,該泥drainage pipe Kangakaritome stepped portion (28A) of the wheel (28) (3
Use as the stopper of 2). Then, a cap (33) fitted with a packing (33A) on the outer periphery is fitted into the outflow side receiving portion (26) to close it.

[0011]

[Effects of the Invention] Therefore, in the present invention, a separate member is not required when using a normal drainage basin as a drop drainage basin, and the work of forming a hole in the bottom of the drainage basin can be easily performed.
