Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a drainage basin which is a synthetic resin basin mainly for sewage buried in a residential land and has improved stability during construction.

[Conventional technology]

Conventionally, the drainage basins were generally made of concrete. However, since the concrete drainage basin is heavy, it is inconvenient to handle, and there is a drawback in that it cannot be transported in large quantities at one time. Therefore, in recent years, concrete basins are being replaced by synthetic resin drainage basins. This synthetic resin drainage basin has many advantages such as being lighter in weight than a concrete basin, easy to construct, and having a smooth sewage flow.

[Problems to be solved by the invention]

However, since the drainage basin made of synthetic resin is extremely lightweight, the current situation is that the installation stability during construction is rather poor. That is, when the drainage basin is placed on a flat place on the ground, the drainage basin stands normally because it is supported by the foot plate and the bottom bottom stabilizer provided on the bottom or side of the basin body. When the drainage basin is left standing in the burying groove, the bottom surface of the groove is uneven, so it tilts or falls. Therefore, there has been a problem that the positioning of the grid during piping cannot be performed accurately.

The present invention has been made in view of such a problem, and an object thereof is to provide a drainage basin that can be accurately installed even if the groove bottom surface is uneven or inclined.

[Means for Solving the Problems]

In order to solve the above-mentioned object, the drainage basin made of synthetic resin of the present invention has a rod-like shape having a length of about 5 to 20 cm at the bottom bottom of the basin body having at least one pipe receiving port and an opening above. The feature is that the body is provided downward.

[Action]

According to the structure of the present invention, during construction of the drainage basin, the drainage basin is allowed to stand still at a predetermined position on the bottom of the groove, and the rod-shaped body provided downward at the lower bottom portion of the basin body is thrust into the soil to form the drainage basin. By pushing it in until it becomes stable, it can be installed in a predetermined position in a normal state. Also, if the length of the rod is shorter than about 5 cm, the stability of the drainage basin will be insufficient and conversely about 20 cm.
If it is longer, it will be too long and inconvenient to handle,
In the present invention, since the length of the rod-shaped body is set within the range of about 5 to 20 cm, such inconvenience does not occur.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a synthetic resin drainage basin 1 according to an embodiment of the present invention.

The drainage basin 1 is obtained by, for example, foam molding of polypropylene resin or injection molding of polyvinyl chloride resin. The drainage basin made of polypropylene with low foaming is extremely lightweight and has high strength, so it is used as a relatively large drainage basin.The drainage basin made by injection molding made of polyvinyl chloride is the former drainage basin. Since it has a larger specific gravity, it is suitable for small drainage basins.

In FIG. 1, reference numeral 2 is a body portion, 3 and 3'are pipe receiving openings for inserting drainage pipes, and 5 is an auxiliary container receiving portion on the upper portion of the body portion 2. In the case of a basin, a pipe made of polyvinyl chloride is inserted into and connected to the auxiliary basin receiving portion 5, and it is cut into an appropriate length to adjust the height with respect to the ground surface.

Further, 6 is a foot portion provided on the lower bottom of the body portion 2 of the drainage basin, for keeping the stability of the drainage basin at the time of installation. Reference numeral 4 denotes a downward rod-like body provided on the lower bottom portion of the container main body, which is formed simultaneously with the injection molding of the container. The rod-like body 4 has a cylindrical shape with a length of about 5 to 20 cm and a diameter of about 1 cm, and its lower end is preferably sharpened so that it can easily be pierced into the soil. Further, when the rod is injection-molded, the resin is not injected into the mold from the position of the rod-shaped body 4 but the sprue generated during the injection-molding of the rod is not specially molded. If you use it as it is,
Usually, sprue, which is treated as scrap, can be effectively used, which is economically advantageous.

FIG. 2 is an AA cut end view of FIG. In FIG. 2, the rod-shaped body 4 provided at the bottom bottom of the rod main body is integrally molded with the resin main body by the same resin, so that the rod-shaped body 4 does not easily come off from the rod. Therefore, it is convenient to insert the rod-shaped body 4 into the soil.

FIG. 3 is a synthetic resin drainage basin 1 according to another embodiment of the present invention.
FIG. 3 is a perspective view of the main body of the cell, and most of the structure of the cell body is substantially the same as that of the cell of FIG. That is, a stabilizing plate 7 is provided below the cell body, and the stabilizing plate 7 is formed integrally with the cell body.
Then, the inclination of this basin is adjusted by the stabilizer 7 during installation. In more detail,
This drainage basin has a small hole 17 formed in the center of the stabilizer plate 7 as shown in the upside down direction in FIG. 4 so that the rod-shaped body 4 manufactured separately can be fitted into the small hole 17. The thicknesses of the end portion 14 and the small hole 17 of the rod-shaped body 4 are adjusted in advance. The rod-shaped body 4 is removed from the drainage basin 1 during transportation and storage, and the drainage basin 1 is fitted when it is carried to the site.

FIG. 5 is a perspective view showing the construction of the drainage basin of the present invention, where G is the ground surface and M is the groove bottom. The groove bottom is flattened out with a predetermined slope, but when the drainage basin 1 is placed on the groove bottom, it is difficult to be in a normal standing state. Therefore, the rod-shaped body 4 is attached to the groove bottom M.
, And fix the main body so that it does not tilt forward, backward, left or right. Then, the drainage pipes 8 and 8'are fitted into the pipe receiving ports 3 and 3 ', respectively. By doing this, even after fitting the pipes 8 and 8 ',
Since the drainage basin 1 can be maintained in a temporarily fixed state by the rod-shaped body 4, it is possible to easily measure the height from the drainage basin 1 to the ground surface G, and an auxiliary basin or pipe (not shown) to be placed on the drainage basin 1. Very convenient when cutting the length of.

The above embodiment shows the case where the rod-shaped body is provided on the lower bottom of the main body of the small-sized rod, but the present invention also includes the rod-shaped body provided on the lower bottom of the large-sized synthetic resin rod body. Needless to say. Further, a plurality of rod-shaped bodies of the present invention may be provided on the lower bottom portion of the main body of the container.

6 and 7 show a rod-like body 4 used in the drainage basin of the present invention.
It is the perspective view which showed the modification. That is, FIG. 6 shows the rod-shaped body 4 in the form of a plate, and FIG. 7 shows the cross-shaped rod-shaped body 4. Thus, the rod-shaped body 4 used in the present invention
The shape is not particularly limited as long as it meets the purpose of the present invention.

[Effect of device]

The drainage basin of the present invention has a rod-shaped body having a length of about 5 to 20 cm facing downward on the bottom bottom of the main body of the drainage basin, so that even if the installation site is inclined or not leveled during construction. By piercing the rod-shaped body at a predetermined position, a remarkable effect that it can be installed and fixed in a normal posture is obtained. Moreover, when the drainage basin is installed and fixed in this way,
When connecting the sewer pipe to the pipe port, the drainage basin does not turn sideways or move from the predetermined position due to the rotation of the pipe, so the construction is easy and the working time can be shortened. can get. Also, the large feet that were conventionally required to support the drainage basin stably
By providing the rod-shaped body of the present invention, it can be made smaller or omitted, so that it becomes more compact depending on the shape of the drainage basin, and there is also an economic merit such as the amount of resin required for molding being reduced. .
