Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rainwater outflow control device for civilian use, and more particularly to a rainwater permeation mass using a small-diameter mass type permeation mass body made of PVC.

[0002]

2. Description of the Related Art Recently, in order to suppress the amount of rainwater flowing into sewers and rivers as much as possible, research and development have been conducted on rainwater outflow control devices such as permeable pavement and rainwater infiltration mass and infiltration connecting pipes. , Many of the results have been introduced.

For example, regarding rainwater infiltration masses, proposals have been made regarding concrete rainwater infiltration masses called shallow or deep single masses, double trouts or triple trouts (for example, Japanese Utility Model Laid-Open No. 63-81987). Publication, Actual Kaihei 3-
54876, etc.).

However, as in the case where the conventional concrete small-sized mass is replaced with a small-diameter PVC-made mass in which an inspection tube is erected on the pipe joint, the concrete-made rainwater infiltration mass is also It is not suitable for rainwater infiltration masses for private use where low cost, compactness and easy handling are required.

Therefore, for example, a synthetic resin upper mass portion integrally provided with a rainwater inflow short pipe and a large number of vertical slit-like water passages, and an outflow short pipe connected to a sewer main pipe, A synthetic resin lower seepage mass part that integrally projects a short pipe for connection that connects to the other upstream rainwater seepage mass.
A rainwater permeation mass is proposed, which is connected by a spigot joint method, and an additional tube that can be changed to a shallow or deep rainwater permeation mass is interposed between the upper mass part and the lower permeation mass part. (See Japanese Utility Model Laid-Open No. 63-121689).

[0006] However, the proposed rainwater infiltration mass does not allow the rainwater infiltration mass to be adjusted in depth depending on the soil quality and the groundwater level at the construction site. There is a problem that it is not possible to cope with this because the short pipe for outflow and the short pipe for connection that have been determined are integrally projected, and the amount of rainwater temporarily stored in the mass main body Even if the diameter of the lower infiltration mass is to be reduced and applied to a private land while maintaining a large size, the lower infiltration mass cannot be deepened, and a dust trap basket is placed on the bottom of the lower infiltration mass. Therefore, this basket has a problem that it is not useful for clogging of the vertical slit-shaped water passage port, and that the handling thereof becomes difficult if it becomes deep.

On the other hand, a large amount is commercially available, for example, 15
A PVC pipe with a diameter of 0 mmφ is cut, and a connecting pipe insertion port and a number of water passages are formed in this pipe, and a lid is attached to the upper end and a bottom plate is attached to the lower end. Rainwater infiltration mass (infiltration strainer pipe) Has been proposed (see Japanese Utility Model Laid-Open No. 4-17477).

However, in such a rainwater infiltration mass,
Although it is possible to use a long PVC pipe in order to reduce the diameter and to temporarily increase the amount of rainwater that can be stored, it is necessary to drill a connecting pipe insertion port and multiple water passage ports in the PVC pipe. There is a problem that there is a lot of work, which leads to an increase in cost, which is not suitable for mass production, and that it is also difficult to attach the dust trap basket.

The mass main body 1 faces downward,
The outer diameter D of the circular cylinder 5 of
This is formed in the connecting cylinder 6. Therefore, the connecting tube 6 is open in the mass body 1. Of course, this connecting cylinder 6 may be formed in the receiving port. In addition, the outer diameter D is the outer diameter of a commercially available PVC pipe (for example, a nominal diameter of 150 to
200 mmφ). A ring-shaped reduced-diameter portion 7 is integrally provided in the opening in the mass main body of the connection cylinder 6, and the dust-reduced portion 7 is hooked to suspend the dust-trapping basket 26 (see FIG. 2). To do. Of course, the ring-shaped reduced-diameter portion 7 may be a reduced-diameter portion that is discontinuous in an arc shape, and in short, may be a hooked portion with which the dust trap basket 26 is locked. Further, arcuate projections 8 are provided on the upper and lower intermediate inner circumferences of the connecting cylinder 6.

A permeation mass portion 9 integrally formed with a perforated bottom portion 10, that is, a permeation mass portion 9 with a perforated bottom portion is detachably attached to the connecting cylinder 6 in a one-touch manner. More specifically, the permeation mass portion 9 is formed into a bucket shape by injection molding, the bottom portion 10 thereof is provided with a large number of water passage openings 11, 11, ... And below the middle of the bucket body portion. There are many vertical slit-shaped water passages 1

A concave portion into which the arc-shaped projection 8 is fitted is formed, and the permeation mass portion 9 is fitted in the connection cylinder 6 in a one-touch manner by utilizing the resin elasticity of the arc-shaped projection 8.

An O-ring 14 is provided between the connecting cylinder 6 and the permeation mass portion 9. Further, the arcuate projection 8 may be provided on the bucket body. Therefore,
The permeation mass portion 9 may be fitted in the connection cylinder 6 only by the O-ring 14 to temporarily prevent the penetration. Of course, the one-touch type mechanism of the arcuate projection 8 and the concave portion may be stopped and a bayonet coupling mechanism (also referred to as a plug joint) not shown may be used.

Next, the operation of the first embodiment will be described. The dust trapping basket 26 (see FIG. 2) is housed in the mass body 1, and the permeation mass portion 9 having the perforated bottom portion 10 is fitted to the connection cylinder 6. On the other hand, the private land, or the land between the private land and the public road, is excavated with a large eye, and this excavated location is permeable sheet 22.
(See FIG. 2) and then put in an appropriate crushed stone 15 or the like. The mass body 1 is installed so as to be surrounded by the crushed stones 15 and the like.

At this time, a PVC inspection tube 16 having a length determined by a shallow type or a deep type is adhesively bonded to the inspection tube receiving port 2, and the connecting pipe receiving ports 3 and 4 are provided with a hole or an ordinary hole. The PVC connecting pipe 30 (see FIG. 2) is adhesively joined.

As a result, when rainwater flows into the mass main body 1 from the upstream connecting pipe 30, dust such as leaves in the rainwater is trapped by the dust trapping basket 26 and then temporarily stored in the infiltration mass section 9. And penetrate. The rainwater that is not stored in the infiltration mass section 9 flows out to the downstream connecting pipe 30, and then to the rainwater infiltration mass (not shown) installed at the next downstream position. Then, when solid matters such as dust are accumulated in the basket 26, the lid (not shown) of the inspection cylinder 16 is removed, and the basket 26
Take out the whole.

In addition, the perforated bottom portion 10 in the first embodiment.
By using a bucket (not shown) having neither the water passage hole 11 nor the vertical slit water passage hole 12 in the permeation mass portion 9 having the above, it is possible to form a reservoir mass. It is advisable to install this storage mass between the rainwater infiltration masses that are connected in series.

Next, a second embodiment of the present invention will be described. In FIGS. 2, 3 and 4, the mass body 1 of the second embodiment is the same as that of the first embodiment, but instead of the permeation mass portion 9 of the first embodiment, A stack-type infiltration mass section 17 is used.

That is, this stacking type infiltration mass 17 is
Soil (If it is a surface loam layer, avoid it and make it deeper)
Depending on the position of the groundwater level (for example, a minimum distance of 1 m) and the amount of rainwater temporarily stored, multiple (2 to 3) of the same shape are stacked. Then, a perforated cap 18 as shown in FIG. 4 is attached to the lowermost penetration mass portion 17b. The single unit, for example, the upper permeation mass 17a is a PVC injection-molded product, and has a mass receiving port 19a formed in the upper part and a mass port 20a formed in the lower part, and a large number of vertical slit water passages 12 in the middle. It is provided. Since the permeation mass 17a in the upper stage is a PVC injection molded product, the water passage port 12 can be easily molded even if it is molded into a lattice-shaped slit or a circumferentially lateral slit.

Therefore, the mass receiving port 19a is adhesively bonded to the connecting tube 6 of the mass body 1 and the mass opening 20a is provided.
Then, the lower mass receptacle 19b is adhesively bonded. At this time, the end of the water permeable sheet 22 is connected to the mass receiving port 19a and the connecting tube 6,
Further, since it can be integrated by being sandwiched between the mass opening 20b and the perforated cap 18, the water permeable sheet 22 can be easily handled.

Next, the permeation mass portion 1 in the upper stage of the second embodiment
A representative example of the dimension of 7a will be described. The axial length H of the upper permeation mass portion 17a is 200 mm, the outer diameter d of the mass receiving port 19a is 230 mm, the slit width a of the vertical slit water passage 21 is a = 5 mm, the pitch is b = 15 mm, and the slit length is c = 12.
It is 0 mm. Therefore, even if the fine soil particles that have passed through the dust trap basket 26 are accumulated on the upper permeation mass portion 17a, the clogging can be considerably delayed by the slit length c.

Next, the receptacle S formed in the mass body 1 and the upper penetrating mass portion 17a in the first and second embodiments will be described in detail. In FIGS. 1, 3 and 4,
The so-called socket length L, which is the axial bonding length of the socket S of the mass main body 1 or the upper penetration mass portion 17a, is defined by JIS.
It is larger than the standard TS joint taper (for example, 0 ° 34 ″ for a nominal diameter of 100 mmφ), but smaller than the taper (for example, 1 ° 8′45 ″ for a nominal diameter of 100 mmφ). TS
Bonding bond length S ₁ and large taper (for example, nominal diameter 1
If it is 00 mmφ, it is composed of a TS bonding adhesive length S _{2 of} 2 ° 17′26 ″) and a surface trim length (about 1 mm) S _3, and S ₁ = 1/2 to 2 / 3L. As a result, the receptacle length L (for example, nominal diameter 10
0 mmφ is 30 mm) JIS standard PVC socket socket length (eg, nominal diameter 100 mmφ is 50 mm)
It turned out that it is possible to shorten it.

Therefore, when the receiving port S is applied to the connecting pipe receiving ports 3 and 4 such as the connecting pipe 30, space saving piping can be realized and the pipe axis can have a slight deflection angle θ. This makes piping work easier. Further, when the receiving port S is applied to the inspection tube receiving port 2 in the mass body 1,
As shown in FIG. 1, since the socket length L is shortened, even in the rainwater infiltration mass installed in the uppermost stream,
It is possible to satisfy the specified minimum minimum soil covering depth h from the ground GL.

Next, a third embodiment of the present invention will be described. In FIG. 6, the mass body 1 according to the third embodiment
Are used in the first and second embodiments, but the following so-called permeation strainer tube 21 is used in place of the stacking type permeation mass portion 17 in the second embodiment.

That is, the outer diameter D of the connecting cylinder 6 of the mass body 1
As described above, since the so-called pipe outer diameter is adjusted, the strainer pipe 21 is adhesively bonded to the connecting cylinder 6 via the socket 23. The perforated cap 18 as used in the second embodiment is attached to the lower end of the strainer tube 21. Therefore, by cutting the strainer tube 21 into a suitable length, it can be adapted to the construction site.
Of course, only the water passage 24 is bored in the strainer pipe 21.

Next, the dust catching basket 26 will be described. In FIG. 7, this dust catching basket 26
An opening edge is formed in accordance with the ring-shaped reduced diameter portion 7 of the mass body 1. In addition, the dust catching basket 26 is
Penetration mass portion 9 which is fitted in the connection cylinder 6 of the mass body 1 in a one-touch manner (refer to the first embodiment, but not the vertical slit-shaped water passage but a circular water passage is shown) Supported by the perforated bottom portion 10 of the. A handle 27 is provided on the basket 26, and the basket 26 is inserted and withdrawn through the inspection tube 16. And the mass body 1 having this basket 26
Can be applied to public as well as private land,
Further, since a plurality of overflow ports 28 having a relatively large diameter are provided in the body of the basket 26, the basket 26 shown in the drawing is also used as a mud reservoir.

The rainwater infiltration mass shown in FIG. 7 has a socket 23 connected to the connecting cylinder 6 and a strainer pipe 21 connected thereto, and the connection pipe receiving ports 3 and 4 are eccentric. A radial pipe joint (also called an increaser) 29 is joined.

[0032]

According to the first aspect of the present invention, the connecting cylinder is joined downward to the permeation mass body 1 of the small-diameter mass type, and the penetrating mass portion of which the depth can be adjusted is joined to the connecting cylinder. , It can be changed as appropriate depending on the amount of rainwater temporarily stored, the difference in soil quality, and the position of the groundwater level.
In addition to facilitating the handling of rainwater infiltration mass in the field,
The reliability of the rainwater penetration mass is improved. Since the synthetic resin permeation mass body of the small-diameter mass type is joined to the synthetic resin permeation mass part with a perforated bottom, it can be molded in one shot with a die, and the cost can be reduced due to the merit of mass production. Since the main body of the small-diameter mass type is used, low cost and compactness are satisfied, it is convenient for rainwater infiltration mass installed in the private area, and it is possible to encourage general spread of the infiltration mass, and control rainwater runoff. Can greatly contribute to
