Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage basin provided in a drainage pipe or a sewer pipe buried underground.

[0002]

2. Description of the Related Art Drainage lines and sewer lines are buried underground. The cross-sectional shape of pipes used for conventional drainage pipes and sewage pipes was often circular or square, but recently these drainage pipes and sewage pipes have a good vertical direction in which even a small amount of drainage or sewage can flow. Many oval tubes with long oval cross-sections were used.

A drainage pipe or a sewer pipe buried in the ground is appropriately provided with a drainage pipe, and the inside of the pipeline is inspected or cleaned by opening the lid of the drainage pipe. You can do it.

The drainage basin has a main pipe which can be connected to a drainage pipe and a sewer pipe, and a basin body having a rising portion formed on the peripheral wall of the main pipe, and a basin body of the basin body. There is a rising pipe and a lid provided on the upper end of the rising pipe.

Conventionally, in this type of drainage basin, the rising portion and rising pipe of the basin body are larger than the main pipe so that the inside of the main pipe can be seen through and a cleaning tool can be smoothly inserted into the main pipe. It is formed with a caliber (see Japanese Utility Model Laid-Open No. 1-185585 and Japanese Utility Model Publication No. 4-12144).

[0006]

However, like the above-mentioned conventional drainage basin, a drainage basin in which the diameter of the rising portion of the pit main body and the riser pipe is larger than the diameter of the main pipe is used for a narrow road or alley in a dense residential area. When it is buried in, the drainage basin almost occupies the road in the width direction, and there is a problem that the piping space for other pipes such as gas pipes, water pipes and power cable storage pipes is lost.

Further, in the conventional drainage basin, since the rising portion, the rising pipe and the lid of the basin main body are projected more largely in the width direction of the main pipe than the peripheral wall of the main pipe, the portion in which the drainage basin is buried is a pipe. There is a problem that the excavation width must be widened compared to the part to be laid, and the construction takes time.

In view of the above, the drainage basin of the present invention focuses on the above problems and reduces the width of the road occupying without impairing the ease of cleaning and inspecting the drainage pipe and the sewer pipe. It is an object.

[0009]

In order to achieve the above object, the drainage basin of the present invention has a main pipe connectable to a drainage pipe and a sewer pipe, and a rising portion is provided on a peripheral wall of the main pipe. A swelling body formed, a rising pipe connected to the rising portion of the swelling body, and a lid provided on the upper end of the rising pipe, the rising portion of the swelling body and the rising pipe. The dimension of the lid in the main axis direction is larger than the diameter of the main tube, and the dimension of the rising portion and the rising tube of the sill body and the lid in the main width direction is substantially equal to or smaller than the dimension in the main axis direction. It was configured.

The main pipe of the present invention has a shape connectable to a drain pipe and a sewer pipe. That is, in the case of a conventional drainage pipe used for a drainage pipe or a wastewater pipe having a circular cross section, a drainage pipe having a main pipe of a substantially circular cross section is used. And recently
In the case of a drainage basin which is used for an oval drainage pipe or a sewage pipe with a vertically long cross section, an oval drainage basin with a cross section of the main pipe being vertically long is used. In this case, the dimension of the rising part, the rising tube, and the lid in the main axis direction of the main tube should be made larger than the dimension of the oval main tube in the short axis direction, and the width of the main tube in the short axis direction of the oval main tube. It is recommended that the size be approximately equal to or smaller than the dimension.

[0011]

In the drainage basin of the present invention, the rising portion of the basin body, the rising pipe, and the length of the lid in the axial direction of the main pipe are larger than the diameter of the main pipe or the length of the short shaft of the oval main pipe. As it is larger than that, you can see it deeply when you open the lid and look inside the main pipe, and you can smoothly insert a cleaning tool into the main pipe.

Further, the dimension of the rising portion, the rising tube, and the lid of the container body in the width direction of the main pipe is substantially equal to or smaller than the dimension in the axial direction of the main pipe, or the length of the short axis of the oval main pipe. As a result, the width that occupies the road is reduced by an amount that is almost equal to or smaller than the length, and it is possible to secure the piping space for other pipes such as gas pipes, water pipes, power cable storage pipes, and the excavation area. It is also possible to shorten the construction period by reducing.

Rising tube 1b connected to the rising part 12 of the
And a lid 1c provided on the upper end of the rising tube 1b. It should be noted that all of these components are synthetic resin molded products.

Further, in the drainage basin 1, the rising portions 12 of the basin body 1a, the rising pipe 1b, and the lid 1c have dimensions L1 and L2 in the main pipe axial direction larger than the main pipe caliber.
Dimensions W1, W2 of the rising portion 12 of the sill body 1a, the rising tube 1b, and the lid 1c in the width direction of the main pipe are smaller than the dimensions L1, L2 in the axial direction of the main pipe, that is, the rising of the sill body 1a. The portion 12 and the rising tube 1b are formed in an elliptical tube shape, and the lid 1c is formed in an elliptical plate shape.

The dimension W1 of the rising portion 12 in the width direction of the main pipe is substantially equal to the diameter of the main pipe, and the dimension W2 of the rising pipe 1b and the lid 1c in the width direction of the main pipe is slightly smaller than that. Therefore, the drainage basin 1 has a structure in which there is almost no protrusion from the peripheral wall of the main pipe 11 in the main pipe width direction. In addition, in the main body 1 of the main body 11, one end of the main pipe 11 and the upper end of the rising portion 12 are processed to have receiving ports, and rubber rings (see FIG. 6) 13 and 14 are attached to the inner periphery thereof.

FIGS. 4 and 5 show a protective hat 2 provided to cover the lid 1c of the drainage basin 1. The protective hat 2 has a tubular portion 21 and a lower end of the tubular portion 21. The tubular portion 2 includes an integrally molded flange portion 22 and a lid 23 that is detachably attached to the tubular portion 21.
1 is formed in an elliptic cylindrical shape corresponding to the rising portion 12 of the sill body 1a and the rising tube 1b, and the flange portion 22 is formed in a shape in which the central portion of a rectangular plate is hollowed out into an elliptical shape. The lid 23 is formed in an elliptical plate shape.

Next, the operation of this embodiment will be described with reference to FIG. FIG. 6 shows a construction state of the drainage basin 1 of the present embodiment, in which the main pipe 11 of the basin body 1a is connected to the drainage pipe P,
The lid 1c is covered with a protective hat 2.

When inspecting the drainage pipe P in such a construction state, the lid 23 of the protective hat 2 is opened, the lid 1c of the drainage basin 1 is removed, and the upper surface of the rising pipe 1b is opened. To do. At this time, the cell body 1a
Since the dimensions L1 and L2 of the rising portion 12 and the rising pipe 1b in the main pipe axial direction are larger than the diameter of the main pipe, the inside of the drainage pipe P can be clearly seen.

When the drain pipe P is to be cleaned, the upper surface of the rising pipe 1b is opened and the cleaning tool B such as a cleaning hose or cleaning brush is inserted from the opening, as in the above case. At this time, the cleaning tool B needs to be inserted vertically into the rising pipe 1b, and after being turned sideways in the main pipe 11 and then inserted into the drain pipe P. The dimension L1 of the pipe 1b in the main axial direction,
Since L2 is larger than the main pipe diameter,
The operation of changing the direction of the cleaning tool B in the main pipe 11 can be easily performed. That is, the work of inserting the cleaning tool B into the drain pipe P from the upper surface of the rising pipe 1b can be performed smoothly.

Further, in the drainage basin 1 of the embodiment, the dimensions W1 and W2 of the rising portion 12 of the basin body 1a, the rising pipe 1b and the lid 1c in the width direction of the main pipe are smaller than the dimensions L1 and L2 in the main pipe axial direction. Moreover, since there is almost no protrusion from the peripheral wall of the main pipe 11 in the main pipe width direction, the drain pipe P
Do not occupy more than the width of the road. Therefore, even when it is installed on a narrow road or alley, it is possible to secure a piping space for other pipes such as a gas pipe, a water pipe, and a power cable storage pipe. Further, if the drainage pipe P is digged so that it can be installed, the drainage pipe P can be buried without excess digging, so that the construction period can be shortened compared to the conventional case.

Next, another embodiment shown in FIGS. 7 to 9 will be described. 7 is a plan view of the drainage basin 1 ', FIG. 8 is a front view thereof, and FIG. 9 is a side view thereof.

Further, regarding the drainage channel and the sewage channel having the same sectional area, the operation of the embodiment shown in FIGS. 7 to 9 is compared with the operation of the embodiment shown in FIGS. The width of the main pipe is smaller than that of the circular one. Then, the rising portion 12 ', the rising tube 1b', and the lid 1
Since the dimension of c'in the width direction of the main pipe is substantially equal to or smaller than the short axis size of the oval main pipe, it does not occupy a wider road than the embodiment shown in FIGS. It can be buried. Other functions are the same as those of the embodiment shown in FIGS.

Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific structure is not limited to this embodiment, and there are design changes and the like within the scope not departing from the gist of the present invention. Also included in the present invention. For example, in the embodiment, the drainage basin is shown in which the rising portion of the container main body and the rising pipe are formed in an elliptic tube shape, and the lid is formed in an elliptical plate shape.

You may. Further, in the embodiment, the connection portion with the drain pipe or the sewer pipe is sealed with the rubber ring, but the drain pipe or the sewer pipe may be connected with an adhesive or the like. Further, the connection between the rising portion and the rising tube is sealed by the rubber ring, but the connection may be made by adhesion or fusion. Further, although the structure of the main portion is only straight, it may be bent, cheese (Y cheese), double Y cheese, or the like.

[0026]

As described above, in the drainage basin of the present invention, the width in the width direction of the main pipe is ensured while ensuring a sufficient width in the axial direction of the rising portion, the rising pipe and the lid of the main body of the drainage pipe. The size of the gas pipes, water pipes, and power cables can be reduced without reducing the workability when inspecting and cleaning drainage pipes and sewer pipes. As a result, it is possible to secure a piping space for other pipes such as a storage pipe, and to reduce an excavation area to shorten a construction period.
