・開発が行われ、その成果が多数紹介されている。2. Description of the Related Art Recently, in order to minimize the amount of rainwater flowing into sewers and rivers, research and development have been conducted on rainwater runoff control devices such as permeable pavements and rainwater infiltration masses and infiltration connection pipes. , Many of its achievements are introduced.

（例えば、実開昭６３−８１９８７号公報、実開平３−
５４８７６号公報等参照）。[0003] For example, regarding rainwater infiltration masses, proposals have been made regarding concrete rainwater infiltration masses referred to as shallow or deep single masses, double masses or triple masses (for example, Japanese Utility Model Application Laid-Open No. 63-81987).

い。[0004] However, as in the situation where the conventional small concrete mass is replaced by a small-diameter PVC mass in which an inspection tube is erected at a pipe joint, the above-mentioned concrete rainwater infiltration mass is also used. It is not preferable for rainwater infiltration mass used in private land where low cost, compactness, and easy handling are required.

る（実開昭６３−１２１６８９号公報参照）。[0005] Therefore, for example, an upper mass section made of synthetic resin in which a short pipe for inflow of rainwater is integrally protruded, a large number of vertical slit-like water inlets are provided, and a short pipe for outflow connected to the sewage main pipe, The lower permeation mass section made of synthetic resin, which has a connecting short pipe integrally connected to the other upstream rainwater permeation mass,
A rainwater infiltration mass is proposed which is connected by a spigot joint method, and in which an additional tube is provided between the upper mass portion and the lower infiltration mass portion, which can be changed to a shallow or deep rainwater infiltration mass. (See Japanese Utility Model Application Laid-Open No. 63-121689).

る、という問題があった。However, even if the proposed rainwater infiltration mass is intended to adjust the depth of the water inlet through which rainwater penetrates depending on the soil quality, groundwater level, and the like at the construction site, the depth of the penetrating mass at the lower part where the water is penetrated is buried. There is a problem that the short pipe for outflow and the short pipe for connection are fixed and cannot be coped with, and the amount of rainwater temporarily stored in the mass body is reduced. Even when trying to reduce the diameter and apply it to a private area while keeping it large, the lower penetration mass cannot be deepened, and a garbage trap is placed on the bottom of the lower penetration mass. Therefore, this basket has a problem that it is not useful for clogging of the vertical slit-shaped water inlet, and it becomes difficult to handle the basket deeper.

Although it is possible to use long PVC pipes in order to reduce the diameter and increase the amount of rainwater temporarily stored, it is necessary to drill holes for connecting pipes and many water holes in each PVC pipe. There is a problem that a large amount of work is required, which results in an increase in cost and is not suitable for mass production, and also a problem that it is difficult to attach a dust trap basket.

Soil quality (If it is a surface loam layer, avoid it and make it deeper)
Depending on the groundwater level (for example, at least 1 m away) and the amount of rainwater temporarily stored, a plurality (two or three) of the same shape are stacked and used. Then, a perforated cap 18 as shown in FIG. 4 is attached to the lowermost penetration mass portion 17b. This single unit, for example, the upper permeation mass 17a is a PVC injection-molded product, in which a mass receiving port 19a is formed above and a mass outlet 20a is formed below, and a number of vertical slit-shaped water inlets 12 are provided therebetween. Is provided. Since the upper permeation mass 17a is a PVC injection-molded product, the water-flow opening 12 can be easily formed even if it is formed into a lattice-shaped slit or a circumferentially-oriented slit.

A representative example of the dimension of 7a will be described. The axial length H of the upper penetration mass 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-shaped water passage 21 is 5 mm, the pitch b is 15 mm, and the slit length c is 12

It is larger than the standard TS fitting taper (for example, 0 ° 34 ”for nominal diameter 100 mmφ), but smaller than taper (for example, 1 ° 8'45” for nominal diameter 100mmφ). TS
The bonding adhesive length S 1, Te - large the path (e.g., nominal diameter 1
If it is 00 mmφ, it is composed of the bonding length S 2 for TS bonding of 2 ° 17′26 ″) and the surface bird length (about 1 mm) S 3, and S 1 = 1/2 to 2 / 3L As a result, while maintaining the adhesive strength for preventing the rainwater mass from falling off as in the present invention, the receiving port length L (for example, the nominal diameter 10
The socket length of the JIS standard PVC socket is 30 mm for 0 mmφ (for example, 50 mm for nominal diameter 100 mmφ).
It has been found that the length may be shorter.
