The assembly 21 includes four main bodies 22 (22A to 22D) arranged at a distance from each other, and a right end portion. And a side plate 24, an upper and lower plate 26, an intermediate plate 27, and the like that integrally connect the main body 22 and the end plate 23 to each other. In FIG. 5, a state in which the side plate (or outer plate) located on the near side is deleted is illustrated. Each of the constituent members can be formed as a molded product using a plastic material, in particular, a resin such as a recycled plastic material, or a composite material in which a plastic material and an inorganic powder are mixed.

As shown in FIG. 6, the main body 22 (22A to 22D) includes a flat base 22a composed of a frame and a reinforcing member, and four truncated cone-shaped protrusions 22b projecting in the vicinity of the four corners of the base 22a. And a through hole 22c penetrating the base 22a. The through hole 22c has a size that allows a human to pass through. Further, the inside of the four protrusions 22b is hollow, and when a plurality of main bodies 22 are stacked one above the other, one protrusion 22b of the adjacent main body 22 is in the cavity of the protrusion 22b of the other main body 22. The plurality of main bodies 22 can be stacked without leaving a gap.

As shown in FIG. 7, the end plate 23 is composed of a flat base 23a composed of a frame and a reinforcing member, and a protruding member 23b. Protruding member mounting portions 123a for mounting the protruding members 23b are formed in the vicinity of the four corners of the base body 23a. The protruding members 23b are composed of a flange portion 223b and a quadrangular pyramid-shaped protruding portion 123b. The projecting member 23b is attached to the base 23a by a concavo-convex structure or the like (not shown) formed in the portion 123a and the flange portion 223b.

As shown in FIG. 8, the side plate 24 includes a flat base 24a made of a frame, a reinforcing member, and the like, and two openings 24b located near the center of the base 24a. The opening 24b is used to insert a suction / cleaning hose or the like. The side plate 24 is disposed between adjacent assemblies 21 when a plurality of assemblies 21 are combined to form a rainwater storage and penetration facility structure.

As shown in FIG. 9, the outer plate 25 is formed in a flat shape composed of a frame and a reinforcing member, and differs from the side plate 24 in that there is no opening 24 b like the side plate 24. The outer plate 25 is provided on the outermost assembly 21 when a plurality of assemblies 21 are combined to form a rainwater storage and penetration facility structure.

When the facility structure is configured, it is arranged on the upper surface of the uppermost assembly 21 or the lower surface of the lowermost assembly 21.

As shown in FIG. 11, the intermediate plate 27 is configured by stacking two plate-like members 27 a and 27 b having a similar configuration to the upper and lower plates 26 shown in FIG. 10 back to back, and combining a plurality of assemblies 21. When the structure for rainwater storage and penetration facilities is configured, it is disposed between two assemblies 21 adjacent in the vertical direction.

The above-mentioned members 22 to 27 are combined to form an assembly 21, and a plurality of assemblies 21 are combined to form a structure for rainwater storage and penetration facility (not shown), which is buried underground. The upper part of the buried rainwater storage and infiltration facility structure is covered with a layer of soil, gravel, concrete, or asphalt, and the structure of the rainwater storage and penetration facility structure is covered with a protective layer such as a nonwoven fabric, so that Inflow of earth and sand into the structure for facilities is prevented.

When the structure for rainwater storage and infiltration facilities having the above configuration is buried underground, as shown in FIG. 5 (only one assembly 21 is shown in the figure), the earth pressure P is received in the horizontal direction. Supports the earth pressure by the end plate 23 located at the end of the assembly 21 and the projecting portion 22b and the projecting portion 23b (there are four pairs) of the main body 22A adjacent to the end plate 23 that face each other. be able to. This eliminates the need for a complicated support structure as in the prior art, enables installation in a short time, and greatly reduces installation costs.

Also, since the main body 22 (22A to 22D) has the same shape, each can be manufactured with one type of mold, and the manufacturing cost of the assembly 21 can be reduced. Further, since the holes 22 into which the protrusions having the same shape as the protrusions 22b can be inserted are formed in each main body 22, a plurality of main bodies 22 are stacked without any gaps in the vertical direction and placed on the ground or the floor surface. A gap can be formed between the main body 22 and the base 22a, so that the main body 22 can be transported without using a pallet, and the transport cost can be reduced.
