Abstract

PURPOSE: To prevent the production cost from increasing even if the connection structure of rainwater pipes is diversified in a yard catch basin. CONSTITUTION: In a synthetic resin yard catch basin, the basin body 1 is constituted separately from a sludge pit 10 with the bottom. A downward connecting cylinder 6 having a diameter as large as possible is formed as a unit in the basin body 1 and the sludge pit 10 is detachably connected to the cylinder 6. Since the basin body 1 is made as variable parts for various kinds of rainwater pipe connection structure and the gravel basin 10 is used in common, the production cost can be economized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rainwater trough made of synthetic resin.

[0002]

[Prior art and its problems] Generally, drainage facilities called masu include sewage masu and rainwater masu.
Rainwater masu collects rainwater that falls on the road surface, residential land, vacant land, etc.
It is a facility for accommodating and inspecting and cleaning the rainwater pipe, and it requires a mud reservoir with a depth of 15 cm or more at the bottom, so that this mud reservoir prevents sediment from flowing into the downstream sewer pipe. I have to.

Therefore, rainwater masu has a structure in which a mud trap is added in place of the sewage masu in comparison with sewage masu. In addition, when this rainwater trough is installed in a residential area or the like and rainwater is collected, it is necessary to attach a grid lid.

By the way, since most of the conventional rainwater trouts are made of concrete, the appearance of synthetic resin rainwater trouts has been demanded because of their low cost, compactness, and connectivity with PVC rainwater pipes. . Therefore, for example, part of a bucket-shaped polypropylene rainwater basin with an inlet for an inspection tube and a spout for outflow / inflow rainwater pipes has been implemented, and a proposal was made to improve this polypropylene rainwater basin. Has also been done.

[0005] For example, in Japanese Utility Model Laid-Open No. 5-22679, a main body made of vinyl chloride is integrally connected to an inspection tube capable of cutting a tube and a lower portion of the inspection tube, and the diameter is gradually expanded downward. In other words, it is proposed that a PVC rainwater masu which is composed of a bottomed mud sump part with a truncated cone shape and has an outflow / entrance bored in this mud sump part and rainwater pipes are inserted into and connected to these entrances / exits. .

[0006] However, in the proposed rainwater basin made of vinyl chloride, although it is possible to adjust the position of the buried depth of the shallow type or the deep type by cutting the inspection tube, it is possible to adjust the depth of the mud reservoir. If you try to adjust, the shape of the mud reservoir is frusto-conical and the bottom cap is covered, so if you change the depth of the mud reservoir, the cap for the bottom will change accordingly. There is also a problem in that cleaning is troublesome because the shape of the mud trap is frustoconical.

[0007] Of course, in the case of a polypropylene rainwater gauze bucket having the above-mentioned inlet for the inspection tube and the outlet for the outflow / inflow rainwater pipe, if the depth of the mud reservoir is changed, There was a problem that it had to be replaced.

[0008] In particular, small-diameter sewage masu made of vinyl chloride is currently being produced in a wide variety of structures regarding the structure for connecting the sewage pipes. In the same way, the mud dam section will also be changed, and although there are two types of mud dam sections, there was a problem that the production cost would be too high for the change.

[0009]

SUMMARY OF THE INVENTION Therefore, the present invention has been made in order to solve these problems, and the gist of the present invention is to connect an inspection tube, which is upward and has a lid and which can be cut off, to an inspection tube. Connection part for sideways, and a plurality of rainwater pipe connections for connecting rainwater pipes, each with a synthetic resin small-diameter rainwater basin downward, the rainwater maser connecting pipe of the largest possible diameter opened in the body By integrally molding, and a bucket-shaped bottomed mud reservoir is detachably connected to the connection cylinder so that the bottomed mud reservoir is common and various rainwater pipes are provided in the bottomed mud reservoir. It is a rainwater truss made of synthetic resin characterized by making it possible to use the rainwater trout main body provided with a connection portion.

The present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. 1 is a sectional view of a first embodiment of the present invention, FIG. 2 is an enlarged detail view of an essential portion of FIG. 1, and FIG. 3 is a partial sectional view of the second embodiment.

The synthetic resin rainwater casks according to the first and second embodiments of the present invention are general-purpose PVC small-diameter sewage sewage (sewage sewage with upright inspection tubes installed on various pipe joints).
The main body is a PVC main body that has a TS connection (also referred to as DV joint) like the one shown in the figure. It is compact and inexpensive, and is suitable for rainwater storage installed in residential land.

A first embodiment will be described. In FIG. 1, 1
Is a PVC injection molded product.
A 200 mmφ inspection tube receiving port 2 is provided, and the sideways 75
~ 100 mmφ inlet and outlet rainwater pipe sockets 3,
4 are provided.

These receptacles 2, 3 and 4 are standard JIS
Although it may be a standard TS splicing socket, it is configured as an adhesive splicing socket as shown in Fig. 2 and described later, which is convenient for compact synthetic resin rainwater gutters. Further, the rainwater pipe receiving ports 3 and 4 are not limited to the illustrated straight type, but are 90L type which is orthogonal to each other in a plan view, 45L type which is bent at 45 ° in a planar view, one which is orthogonal to the straight type or It may be a confluent type with two receiving ports added, or any type used for small-diameter wastewater for starting point. Therefore, in the main body 1, the types of the rainwater pipe receptacles 3 and 4 can be diversified to make a product lineup, and if the standard-type mud reservoir 10 described later is shared, the cost can be reduced as a whole. Moreover, since the connection strength with the rainwater pipe can be maintained, it is convenient for the diversified rainwater in the residential land.

This masu body 1 has a downward facing body 1
The outer diameter D of the circular body 5 of No. 3 is extended as it is to obtain the opening length,
This is configured as the connecting cylinder 6. This connecting tube 6 is increasingly open in the main body 1. Therefore, since the diameter of the connecting cylinder 6 can be made as large as possible, it is possible to increase the mud-storing capacity while using rainwater with a small diameter. In addition, the outer diameter D of the connecting cylinder 6 is configured to match the outer diameter of a commercially available PVC pipe (for example, a nominal diameter of 150 to 200 mmφ). If the PVC pipe is made porous, it is possible to immediately permeate the strainer type rainwater.

A diameter-reducing ring 7 is integrally provided at the opening of the connecting cylinder 6 in the main body.
An opening flange of the sediment catching basket 8 having a drainage hole at the bottom can be loosely fitted. Of course, this basket 8 may be suspended by hooking the opening flange of the sediment trapping basket 8. The basket 8 is provided with a lowering hand 8a which is always erected. An arcuate claw 9 is provided around the upper and lower inner circumferences of the connecting cylinder 6.

The connecting cylinder 6 is provided with a bucket-shaped bottomed mud reservoir 10 which is detachable in one-touch manner. That is, the bottomed mud sump portion 10 is a PVC injection molded product, and a stopper-step portion 12 with which the lower end of the connecting cylinder 6 abuts is formed above the middle of the upper and lower outer circumferences of the bucket body portion 11. There is. Above the stopper-step portion 12, a concave portion into which the arcuate claw 9 is elastically deformed and fitted, and an O-ring 13 are provided.
And a recess in which is inserted. As the standard type, the bottomed mud sump portion 10 has a mud sump depth of about 160 mm, but mud sump depths of about 300 mm and about 500 mm are also provided.

Of course, when the arcuate claws 9 are provided on the outer circumference of the bucket body 11, these two recesses are provided on the inner circumference of the connecting cylinder 6.

Next, the structure of the receiving port S for the inspection cylinder and the rainwater pipe provided on the main body 1 will be described. In FIG. 2 showing the rainwater pipe receiving port, the receiving port length L of the receiving port S provided on the main body 1 is changed to the first bonding length S ₁ , the second bonding length S _2, and the guide portion length S _3. in constructed, and this _{S 1 = 1 / 2~2 / 3L} . Further, the first surface taper having the second adhesive length S ₂ is used.
It is larger than the surface taper with the adhesive length S ₁ . In particular, S
₁ surface taper (for example, 1 ° for nominal diameter 100 mmφ)
8'45 °) and S ₂ surface taper (for example, nominal diameter 1
In case of 00 mmφ, 2 ° 17'26 ″) is JIS standard TS
Joining surface taper (for example, 0 ° in case of nominal diameter 100mmφ
34 ").

Therefore, in this synthetic resin rainwater basin, the socket length L (for example, 30 mm in case of a nominal diameter of 100 mmφ) is J while maintaining the adhesive strength in order to prevent coming off.
It has become possible to reduce the length from the IS standard PVC pipe TS joint receiving port length (for example, 50 mm for a nominal diameter of 100 mmφ).

Therefore, when the receiving port S is used as the rainwater pipe receiving ports 3 and 4, space saving piping can be realized, and a slight deflection angle θ can be given to the pipe axis. Plumbing becomes easy.

Further, when the receiving port S is used as the inspection tube receiving port 2, even in the rainwater trough installed in the uppermost stream of the house,
It is possible to secure the specified minimum depth of soil cover from the ground.

Next, the operation of the first embodiment will be described. Select the bottomed mud sump part 10 with a mud depth corresponding to the buried place such as the residential land or the boundary between the residential land and the public road, and also have the main body 1 that has a rainwater pipe fitting that fits the PVC rainwater pipe 15 Choose and fit both. And the basket 8 for catching earth and sand
Is stored and placed in the bottomed mud trap 10. On the other hand, the inspection tube 14 adjusted to the buried depth is adhesively bonded to the inspection tube receiving port 2.

After installing the synthetic resin rainwater trough as described above between, for example, the synthetic resin rainwater troughs, a rainwater pipe (may be a perforated permeation pipe) 15 is attached to the rainwater pipe receiving port 3, 4 is adhesively bonded. At this time, if the rainwater basin is also used for collecting water, the grid cover 16 is attached to the inspection cylinder 14. When the sediment collecting basket 8 is filled with sediment by the rainwater trough installed in this way, the basket 8 is taken out and removed. The grid lid 16 uses the small-diameter sewage lid as it is by simply providing a large number of through holes in the sewage lid.

Next, a second embodiment will be described. FIG.
In addition, the main body 1 of the second embodiment is a confluent type in which three or more rainwater pipe inlets are provided, and these rainwater pipe inlets 3, 4, 4'are eccentric different diameter pipes. The joints 17 are respectively mounted, and the rainwater pipes are bonded and joined thereto. Therefore, the rainwater basin of the second embodiment has a large capacity in the mud trap portion 10, and is therefore preferably installed in a place where a large amount of inflowing sediment is present.

In the above embodiments, the connecting cylinder 6 is described as a spigot, but the outer diameter of the circular cylinder 5 may be slightly reduced to form a receiving mouth, and the earth / sand trapping basket 8 may be used. Although the basket 8 is not necessarily used, a simple storage may be made without using the basket, and the arcuate claw 9 and the recess are explained by fitting by resin elastic deformation. (Also referred to as a plug joint).

Further, instead of the bottomed mud reservoir 10 fitted in the connecting cylinder 6 of the present invention, a synthetic resin penetrating portion having a slit or the like may be fitted in the main body 1 more and more. By doing so, the rainwater can be immediately introduced and configured.

[0027]

According to the present invention, a downward connection pipe is integrally formed on the rainwater trough body by integral molding, and a certain kind of bottomed mud reservoir having different mud depth is connected to the connection pipe. Therefore, it is possible to provide rainwater masu that is inexpensive and suitable for the construction site as a common mud trap.

That is, since the downward connection pipe is integrally formed and extended in the rainwater masu body having various rainwater pipe connections, and the standard mud sump is connected to this connection cylinder, the common mud sump is used. However, it is possible to provide various types of rainwater basins according to the piping condition of the rainwater pipes, and therefore, even if the connection structure of the rainwater pipes is diversified, it is possible to provide an inexpensive rainwater basin.

Although a rainwater masquerade adds a mud reservoir to the production cost as compared with a sewage masque, the production cost is burdened, but the burden can be reduced because the mud basin is shared.

Since the main body and the mud reservoir are separately molded, the molding die is small and inexpensive, and the production cost can be reduced. In particular, since the main body of the masu is similar in size and shape to the main body of the small-diameter wastewater, a general-purpose molding machine for the small-diameter wastewater masu can be used as it is.
