Abstract

<P>PROBLEM TO BE SOLVED: To save resources in a rainwater storage penetration facility using unit members. <P>SOLUTION: In the storage penetration facility for rainwater or the like having separately disposed unit members in which a storage space is formed by arranging unit members under the ground, the storage space is formed by disposing each main unit member with a fixed distant space, connecting the space by a sub-unit member, and forming a ceiling by disposing ceiling members so as to extend over the spaced main unit members. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

The present invention belongs to the technology of rainwater storage and penetration facilities.

For the purpose of suppressing the outflow of rainwater, rainwater storage and infiltration facilities are widely used in which unit members made of plastic or the like are filled underground and covered with a sheet as appropriate. For this purpose, various shapes of members are disclosed in, for example, JP-A-62-101097, JP-A-62-126179, JP-A-9-296486, JP-A-10-252108, JP-A-10-115778, JP-A-11-43971, It is proposed and used in JP-A-11-222886. In any method, a member is disposed, and its periphery is wrapped with a water-permeable or water-impervious sheet, and a storage and penetration facility for storing rainwater in its internal space is obtained.
There was no way to save resources by devising the arrangement of the unit members.

The present invention is a proposal for resource saving of a rainwater storage and penetration facility using unit members.

In the storage and infiltration facility such as rainwater in which the storage space is formed by arranging the unit members in the basement, the main unit members are arranged with a certain distance interval, and the interval is a sub unit member. It is a storage and infiltration facility for rainwater or the like that is formed by separating unit units that form a storage space by forming a storage space and covering the ceiling with a ceiling member so as to straddle the main unit members spaced apart from each other. . In order to save resources, the unit members are arranged at intervals.

In the present invention, the main unit members are arranged at a distance from each other, the main unit members are joined by the sub unit members, and the ceiling portion is provided so as to straddle the unit members arranged at a distance from each other. The necessary number of unit members can be reduced while maintaining the outlook.

Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is a conceptual diagram of a storage space in which unit members of the present invention are arranged apart from each other.
As shown in the figure, the main storage space represents the main unit member as a rectangular parallelepiped having a square plane indicated by a dotted line. As shown in the plan view, the four corners of the storage space are arranged so that each of the main unit members is square, and the main unit members are arranged at a distance of 1/2 of the plane square length of the main unit members between them. is doing.
The ceiling member is a square plate that is 1.5 times the planar square length of the main unit member. By taking such a dimensional shape, the ceiling member can cover the arranged main unit members without a gap.

Although the main unit members are expressed as planar rectangular parallelepipeds, they can be arranged in the same manner as described above and covered with a ceiling plate even if they can be expressed as planar rectangular parallelepipeds.

The sub-unit member is used to connect the main unit members arranged at intervals and maintain the intervals. In the cross-sectional view of FIG. 1, the main unit members are displayed as being coupled to each other, but a plurality of unit members may be coupled together.
The sub-unit member is for coupling the main unit members, and the shape of the main unit member can be changed according to the position, such as the shape, the uppermost part, and the lowermost part. The arrangement method of the sub unit member is as shown in FIG.

FIG. 2 illustrates the present invention taking a container-like member as an example of the conventional unit member shown in FIG.
As shown in the plan view, as in FIG. 1, the four corners of the storage space form a square with four container-like members. The ends with a width of / 2 are repeated, and the end ends with a square composed of four container-like members.
As shown in the cross-sectional view, the sub-unit member is used for maintaining the interval and joining the main unit members every two main unit members.

The above storage space is constructed in the basement, and the side of the storage space is covered with appropriate wall materials, covered with sheets to prevent infiltration of soil and sand into the storage space, inflow pipe, outflow pipe, overflow pipe, mud storage, human As in the case of the conventional unit member, it can be used as a storage and permeation facility for rainwater by providing ancillary facilities such as holes and orifices as necessary. When the sheet is used as an infiltration tank depending on the level of groundwater, a water-permeable sheet is also used for the purpose of preventing the intrusion of groundwater or effective use of stored rainwater.

The material of the main unit member and the sub unit member can be made of an injection-moldable polyolefin such as polypropylene or a metal such as stainless steel, like the conventional unit member.

It is a conceptual diagram which shows the storage space which arranged the unit member at intervals of this invention. It is an example which shows the storage space which arranged the unit member at intervals of this invention. The example of the conventional unit member is shown.

Claims (1)

In storage and infiltration facilities, such as rainwater, where storage spaces are formed by arranging unit members underground, each main unit member is arranged with a certain distance interval, and the intervals are combined with sub unit members for storage. A storage and permeation facility for rainwater and the like in which unit members are arranged apart from each other, wherein a storage space is formed by forming a space and covering the ceiling with a ceiling member so as to straddle the main unit members spaced apart from each other.
