1 to 3 show a first embodiment of the present invention.
It will be described based on. First, in FIG. 1, a cylindrical box body 1 is buried in the residential land. This basin body 1
Is manufactured by injection-molding polypropylene. As shown in FIG. 2, a main socket portion 1a, a sub-socket portion 1b, and a drain socket portion 1c are integrally formed on the outer peripheral surface of the cell body 1. ing.

Main socket 1a and sub socket 1b
As shown by a two-dot chain line in FIG.
a and 2b (for example, those connected to a flush toilet or the like) are connected. Therefore, the drainage flowing down the pipes 2a and 2b flows into the main body 1 through the main socket portion 1a and the sub socket portion 1b. The pitch between the main socket portion 1a and the sub socket portion 1b is set to 90 °.

A main drainage groove 1d and a sub-drainage groove 1e swelling downward in a U-shape are formed on the bottom surface of the box body 1.
The drainage flowing from the main socket portion 1a into the box body 1 flows down in the direction of arrow A along the main drainage groove 1d, and the drainage flowing into the box body 1 from the sub socket portion 1b is drawn into the sub-drainage channel 1
It flows down in the direction of arrow B along e. The sub-drain 1e
Intersects with the main drain ditch 1d at a predetermined acute angle θ, and the drain water flowing down the sub drain ditch 1e is
And then flows down in the direction of arrow A.

A pipe 2c connected to a public sewer pipe is connected to the drain socket 1c. Therefore, the main drain 1
The drain water flowing down from the drain socket 1c is connected to the pipe 2c.
Down to the public sewer through. Note that reference numeral 1f in FIG.
Indicates a leg integrally formed on the lower surface of the box body 1. The main drain 1d and the sub-drain 1e are inclined downward from the right to the left in FIG. 1, and the flow of drainage smoothly proceeds based on the inclination of the main drain 1d and the sub-drain 1e. Will be

As shown in FIG. 1, a female thread 3a is formed at the upper end of the box body 1 on the inner peripheral surface of the box body 1. In this case, the box body 1 is manufactured by a rotary injection molding machine (not shown), and the female thread portion 3a is formed.
Is integrally formed with the box body 1 by simultaneously pulling out the mold while rotating it to a predetermined position and opening the mold. It should be noted that the female thread portion 3a is, as shown in FIG.
Projecting inward from the general surface 1g, and are formed at four locations at 90 ° pitch.

FIG. 1 shows a plurality of female threads 3a of the box body 1.
As shown in the figure, the male screw portion 3b of the adjuster 4 corresponding to the cylindrical member is screwed. The adjuster 4 is manufactured by a rotary injection molding machine (not shown) using polypropylene as a material.
Is formed integrally with the adjuster 4 over the entire circumference of the adjuster 4. Then, the female screw portion 3a and the male screw portion 3
b is filled with an adhesive, and this adhesive is

Reference numeral 3 denotes a female thread 3a and a male thread 3
b shows a screw portion composed of Reference numeral 5 denotes a height adjusting mechanism including the screw portion 3 and the adjuster 4.

At the upper end of the adjuster 4, a receiving groove 4a having a U-shaped cross section is formed integrally. The receiving groove 4a is formed over the entire circumference of the adjuster 4. The convex portion 6a of the disc-shaped lid 6 is fitted into the receiving groove 4a. It is closed by the lid 6. The lid 6 is manufactured by injection-molding polypropylene, and prevents rainwater or the like from flowing into the tub body 1 from the upper opening of the adjuster 4.

FIG. 3 shows the lid 6. Here, the convex portion 6 a of the lid 6 is integrally formed over the entire circumference of the lid 6. On the upper surface of the lid 6, two handle portions 6b for detaching the lid 6 from the adjuster 4 are integrally formed.

In installing the drainage basin configured as described above, the adjuster 4 is rotated in FIG. 1 to adjust the amount of screwing of the adjuster 4 into the basin body 1 and to adjust the pipes 2a to 2c. Adjust the height of the drainage basin according to the burial depth. Then, an adhesive is filled in a gap between the female thread portion 3a of the main body 1 and the male screw portion 3b of the adjuster 4, and sealing and fixing between the main body 1 and the adjuster 4 are performed. Next, a drainage basin is buried at a predetermined position in the residential land, and the pipes 2a to 2c are connected to the socket portions 1a to 1 of the basin body 1.
c in the receiving groove 4 a of the adjuster 4.
Are fitted.

According to the above embodiment, the height of the drainage basin is adjusted by changing the amount of screwing of the adjuster 4 to change the amount of overlap of the adjuster 4 with respect to the basin body 1. For this reason, compared with the conventional case where the height of the drainage basin is adjusted by the combination of the adjusters, the types of the adjusters 4 are reduced, and as a result, the cost of the drainage basin is reduced. At the same time, there is an advantage that the height of the drainage basin can be adjusted in a fine unit corresponding to the pitch between the female screw portion 3a and the male screw portion 3b.

In order to cover the range of 120 mm, conventionally, it is necessary to manufacture six types of adjusters having different lengths by 20 mm. On the other hand, in this embodiment, if the lengths of the female screw portion 3a and the male screw portion 3b are each set to 60 mm, the range of 120 mm can be covered by one type of adjuster 4.

Further, the female thread portion 3a is integrally formed on the box body 1, and the male screw portion 3b is integrally formed on the adjuster 4. For this reason, the number of manufacturing steps is reduced as compared with the case where the female thread portion 3a and the male screw portion 3b are engraved after the molding of the basin body 1 and the adjuster 4, and as a result, the cost of the drainage basin is further reduced. The adjuster 4 has a receiving groove 4a.
Is formed, and the convex portion 6a of the lid 6 is fitted into the receiving groove 4a. Therefore, the space between the adjuster 4 and the lid 6 is sealed, and as a result, odor leakage from the inside of the cell body 1 is prevented. In addition, since the handle 6b is formed on the lid 6, it is easy to remove the lid 6 when cleaning the inside of the box body 1, for example.

In the first embodiment, the cell body 1
The female thread 3a is formed on the adjuster 4 and the male thread 3 is formed on the adjuster 4.
Although b is formed, the present invention is not limited to this, and a male screw portion may be formed in the box body 1 and a female screw portion may be formed in the adjuster 4.
