As shown in FIG. 1, the rainwater storage and penetration facility 201 includes at least the inspection member 226 of the present embodiment, and further includes a plurality of inflow masses 2 and a plurality of rainwater storage and penetration tanks 6.

  The inflow mass 2 is a member for collecting rainwater flowing down from the street G provided on the road, and is buried in the ground below the street G as shown in FIGS. 1 (a) and 1 (b). The plurality of rainwater storage and penetration tanks 6 are provided in the extending direction. Moreover, it is preferable that the inflow mass 2 is provided in the width dimension of each rainwater storage penetration tank 6.

  The inflow mass 2 in the rainwater storage and infiltration facility 226 of the present embodiment is configured by a first inflow mass 14 and a second inflow mass 15 arranged in the extending direction of each rainwater storage and infiltration tank 6. The first inflow mass 14 includes a lid 16 b, a filter 17, a rainwater storage unit 18, and a filter 19. The lid 16a has no or few open portions, and the rainwater collected in the street lamp G flows over the lid 16a. The lid 16b is formed in a net shape in plan view, and rain water collected in the street G can be allowed to flow into the inflow mass. The filter 17 is for removing the dust and dust from the rainwater by filtering the rainwater that has flowed down, and is made of, for example, a plastic or stainless steel colander. The rainwater storage section 18 is for temporarily retaining rainwater flowing down from the street G through the lid 16b and the filter 17 to roughly settle and separate earth and sand, and is composed of a mass made of concrete, for example. Has been. The filter 19 is for removing finer dust and dirt from the rainwater in the rainwater storage portion 18 and is provided on the first inflow mass 14 side of the connecting pipe 20 between the first inflow mass 14 and the second inflow mass 15. ing. The filter 19 is made of, for example, a stainless steel net having a large number of water passage holes smaller than the filter 17.

  The second inflow mass 15 is connected to the first inflow mass 14 by the connecting pipe 20, and temporarily stores rainwater flowing in from the first inflow mass 14 and supplies it to the upper part of the rainwater storage and penetration tank 6. And includes the same components as those of the first inflow mass 14 except for the lid 16 b and the filter 17.

  The second inflow mass 15 and the rainwater storage permeation tank 6 are connected by an inflow pipe 10.

Thereby, the air stored in the upper part of the rainwater storage and permeation tank 6 is extracted from the second inflow mass 15 or the first inflow mass 14 to the ground through the inflow pipe 10. Moreover, as shown to Fig.1 (a), the inflow pipe 10 descend | falls in the direction which leaves | separates from the street G as it advances to the rainwater storage penetration tank 6 side from the 2nd inflow mass 15 side. As a result, rainwater temporarily stored in the second inflow mass 15 is smoothly supplied to the rainwater storage and penetration tank 6. In addition, illustration of the inflow pipe 10 and the receiving port 11 is abbreviate | omitted in FIG.1 (b).

  The rainwater storage and penetration tank 6 is for temporarily storing the rainwater flowing in from the inflow mass 2 while flowing down from the upper stage to the lower stage, and for discharging it into the ground from the lower stage, for example, injection molding or extrusion molding. It is comprised with the frame member which consists of plastics, such as a polypropylene formed by. Specifically, the rainwater storage and penetration tank 6 is configured by a plastic lower assembly member 21 (frame member) and an upper assembly member 22 (frame member) capable of flowing rainwater downward, and the lower assembly member 21.
