Abstract

(57) [Summary] [Purpose] The present invention aims to provide a drainage basin that combines both a normal drainage basin and a drop drainage basin. [Structure] A mud ring 28 with a predetermined inner diameter is formed on the bottom surface 27 of an ordinary drainage basin.
If a step portion 28A is provided on the inner periphery of the mud wheel 28 to form a receiving structure and the drainage basin is a drop drainage basin 20A, the inside of the mudwheel 28 is cut open to The drainage pipe 32 is connected with 28 as a receptacle.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drainage basin having both a normal drainage basin and a drop drainage basin.

[0002]

[Prior Art]

 As shown in FIG. 5, in a normal drainage basin (10), an inlet (12) and an outlet (13) are provided on the side surface of the main body (11). In order to use it as a drainage basin, a hole (15) is made in the bottom surface (14) and a connecting cylinder (16) having a collar (16A) is fitted in the hole (15) and the outlet ( There is provided a construction in which 13) is closed by a stopper (17) (Jitsuko 62-43037).

[0003]

[Problems to be solved by the device]

 However, in the above conventional configuration, there are problems that the connecting cylinder (16) must be prepared as a separate member, and that it takes time to determine the position and diameter of the hole (15). .

[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 the bottom surface (27) and forming a step portion (28A) on the inner circumference of the mud wheel (28). It provides a drainage basin (20) with a receiving structure.

[0005]

[Action]

 When the drainage basin (20) is used as a drop drainage basin (20A), the inner part of the mud ring (28) on the bottom surface (27) of the drainage basin (20) is cut off to provide a hole (31). Since the mud ring (28) has a stepped portion (28A) formed on the inner circumference to have a receiving structure, the drain pipe (32) is connected to the mud ring (28) to form the stepped portion. (28A) is used as a stopper for the drain pipe (32).

[0006]

【Example】

 The present invention will now be described with reference to an embodiment shown in FIGS. An inlet (23, 24, 25) and an outlet-side inlet (26) are provided, and a bottom surface (27) is provided with a mud ring (28). A stepped portion (28A) is formed on this to form a receiving structure. 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) of the main body (21).

In the drainage basin (20), the inner diameter of the outlet side receiving part (26) (the outer diameter of the drain pipe connected to the receiving part (26)) and the inner diameter of the mud ring (28) are They are made equal, and are set to, for example, 150 mm, and the inner diameters of the inlet side receiving portions (23, 24, 25) are set to, for example, 100 mm.

When the drainage basin (20) is used 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 tube is connected to the receiving port (22), an inflow pipe is connected to the inflow receiving port (23, 24, 25), and a drain pipe is connected to the outflow receiving port (26).

When using the drainage basin (20) as the drop drainage basin (20A), the tip of the center leg (30A) of the compass-shaped cutter (30) is attached to the mud ring (28) as shown in FIG. Of the mud ring (28) on the bottom surface (27) of the drainage basin (20) by contacting the center hole (29A) of the boss (29) at the center of the Cut off the inner part (27A).

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 received as shown in FIG. It is connected to the muddy wheel (28) that functions as a stopper, and the stepped portion (28A) of the muddy wheel (28) serves as a stopper for the drain pipe (32). Then, the outlet side inlet (26) is closed by fitting a cap (33) having a packing (33A) on its outer periphery.

[0011]

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