Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drainage basin provided in the middle of a drainage pipeline buried underground.

[0002]

[Prior art]

 The drainage basin provided in the middle of the drainage pipe has an inlet and an outlet formed sideways, and a main body of the drainage pipe with an upward branch, and a receiving port at one end. There is a riser pipe which is fitted to the branch port of the main body of the rising pipe and a lid provided so as to close the upper end of the riser pipe.

Further, in the construction method of the drainage basin, a lid of the drainage basin is provided at a position lower than the road surface, a lid provided on a rising pipe of the drainage basin is covered with a protective hat, and the lid of the protective hat is covered by the road surface. There is a method of exposing the same (see Japanese Utility Model Laid-Open No. 1-185585). In this construction method, the protective hat is installed so as to float above the lid of the drainage basin, so even if an automobile, etc. passes over the lid of the drainage basin, the load is not directly applied to the drainage basin. It is possible to prevent the drainage basin from being damaged by the load of an automobile or the like.

[0004]

[Problems to be solved by the device]

 However, in the case of the above-mentioned conventional drainage basin, even if it is installed in the ground by the above-mentioned construction method, the protective hat is sunk or lifted in a region where the ground is soft or where freezing is remarkable such as in cold regions. As a result, the relative position of the drainage basin may shift, and the load from the ground may be transmitted to the drainage basin. In such a case, there was a risk that the rising pipe would fall along the branch opening of the main body of the pipe, and the receiving end of the rising pipe would be forcibly expanded or the main body of the container would be crushed and damaged.

The present invention focuses on the above problems, and aims to provide a drainage basin that is strong against the load from the ground and can be applied even in an area where the ground is soft, or in an area with severe freezing such as a cold area. I am trying.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, in the drainage basin of the present invention, a basin main body is formed with an inflow port and an outflow port in a lateral direction, and a branch port is formed in an upward direction, and a receiving port is formed at one end. In a drainage basin comprising a rising pipe fitted to the branch opening of the basin body with the receiving port facing downward, and a lid provided to close the upper end of the rising tub, a drainage basin of the basin body A stopper for restricting the downward movement of the rising pipe is formed on the outer circumference.

[0007]

[Action]

 In the drainage basin of the present invention, even if a load on the ground acts on the rising pipe, the rising pipe is restricted from moving downward by the stopper formed on the outer periphery of the branch opening of the main body of the container. Therefore, it is possible to prevent the rising pipe from falling along the branch opening of the main body of the container.

[0008]

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. FIG. 1 is a cross-sectional view showing a working state of the drainage basin of the embodiment, in which 1 is a drainage basin, 2 is a protective hat, and 3 is a pedestal ring.

The drainage basin 1 is composed of a basin body 11, a rising pipe 12 and a lid 13, which are all made of synthetic resin moldings. The basin body 11 has an inlet 11a into which the drainage pipe P1 is inserted and an outlet 11b into which the drainage pipe P2 is fitted, and a branch port 11c into which the rising pipe 12 is fitted. It is formed so as to face upward, and a stopper 11d that restricts the downward movement of the rising pipe 12 is continuously formed in an annular shape on the outer periphery of the branch port 11c. A rubber ring 14 is attached to the inner surface of the inflow port 11a. The rising pipe 12 has a receiving opening 12a formed with a rubber ring 15 at one end, and is fitted into the branch opening 11c of the basin body 1 with the receiving opening 12a facing downward. The lid 13 is provided so as to close the upper end of the rising tube 12.

The protective hat 2 has a tubular portion 21, a flange portion 22 integrally formed at the lower end of the tubular portion 21, and a top and bottom of the tubular portion 21 which are pivotable via a hinge 23. And a lid 24 provided on the drainage basin 1 to cover the lid 13 of the drainage basin 1. The protective hat 2 is arranged so as to be floated from the lid 13 of the drainage basin 1 so that a part thereof does not come into direct contact with the drainage basin 1, and only the upper surface of the lid 24 is exposed to the road surface. ing.

The pedestal ring 3 has a recess 31 formed in the upper surface thereof, into which the flange portion 22 of the protective hat 2 is fitted, and is inserted in the rising pipe 12 of the drainage basin 1 and is buried in the ground. . The pedestal ring 3 is aligned so that its center is almost directly above the center of the lid 13 of the drainage basin 1, and the inner peripheral portion of the pedestal ring 3 and the outer circumference of the rising pipe 12 of the drainage basin 1 are aligned. A constant space is maintained between the parts.

Next, the operation of this embodiment will be described.

As described above, if the protective hat 2 is installed so as to float above the lid 13 of the drainage basin 1, even if an automobile or the like passes over the lid 24 of the protective hat 2, the load is directly applied to the drainage basin 1. Since it is not applied to the drainage pipe, it is possible to prevent the drainage basin 1 from being damaged by the load of the automobile or the like.

Further, in a region where the ground is soft or a region where freezing is remarkable such as in a cold region, the protective hat 2 is sunk or lifted, and the relative position with respect to the drainage basin 1 is displaced, so that the load from the ground drains. It may be transmitted to Masu. In such a case, the load on the ground rises and acts on the rising pipe 12, but the rising pipe 12 is restricted from moving downward by the stopper 11d formed on the outer periphery of the branch opening 11c of the sill body 11. Therefore, it is possible to prevent the rising pipe 12 from dropping along the branch opening 11c of the sill body 11, and to prevent damage to the swell body 11 and the rising pipe 12.

Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and there are design changes and the like within a range not departing from the gist of the present invention. Also included in the present invention. For example, in the embodiment, the container main body is shown in which the stopper is continuously formed in an annular shape on the outer circumference of the branch opening, but the stopper may be formed intermittently on the outer circumference of the branch opening. Further, the stopper is not limited to the protrusion and may be formed by a step.

Further, the inner side of the receiving port may be expanded in diameter. The material of the container body may be a thermoplastic resin such as vinyl chloride resin or a thermosetting resin such as FRP. Further, the inlet and outlet of the main body of the sluice may be a receiving port or a spout, and in the case of the receiving port, an adhesive type may be used.

[Effect of device]

 As described above, in the drainage basin of the present invention, even if a load on the ground acts on the rising pipe, the rising pipe can be prevented from falling along the branch opening of the main body of the basin. This has the effect that it can be applied to areas with severe freezing, such as soft areas and cold regions.
