As shown in FIG. 2, the filling material made of the synthetic resin of the present invention used for the above filling structure is integrally formed with a plurality of vertical short pipes 7 that can be connected vertically on both sides of the horizontal pipe 6 via connecting pieces. Therefore, such a filler can be mass-produced at a relatively low cost by injection molding using a single mold.
[0032]
More specifically, this filler is composed of a total of four vertical short tubes 7 (7a, 7b, 7c, 7d), two on each side of the horizontal pipe 6, and three sets of vertical short tubes 7 are equally spaced. The horizontal pipe 6 is formed as a round pipe having a length of 1000 mm, an outer diameter of 100 mm, and a thickness of 2 mm. The vertical short pipe 7 is formed as a short round pipe having a height of 125 mm, an outer diameter of 100 mm, and a thickness of 2 mm, and the vertical short pipes 7 a and 7 d facing each other in the direction perpendicular to the horizontal pipe 6. The distance between 7b and 7c is set equal to the distance between the vertical short pipes 7a and 7b and 7d and 7c facing each other in the direction parallel to the horizontal pipe .

A water passage hole 9 is formed in the filling horizontal pipe 6 and the vertical short pipe 7, and rainwater can flow into the horizontal pipe 6 and the vertical short pipe 7 from the water passage hole 9. . Therefore, if this filler is filled into the rainwater storage and penetration tank 1 in the manner described later, the rainwater in the tank flows into the horizontal pipe 6 or the vertical short pipe 7 and is stored. It can be minimized.
[0035]
Further, as shown in FIGS. 9 and 10, a small hook-shaped locking portion 10a is formed at one end of the horizontal pipe 6 of the filler, and the other end can be engaged with the locking portion 10a. A character-shaped engaging portion 10b is formed. Therefore, the horizontal pipe 6 of the filler can be securely connected so as not to be separated by engaging the engaging portion 10b at the other end of the next horizontal pipe 6 with the engaging portion 10a at one end thereof. ing.
[0036]
When filling the inside of the rainwater storage and penetration tank 1 with the filler as described above, first, the flat plate 5 is laid on the water-permeable sheet 16 on the bottom surface of the rainwater storage and penetration tank 1, and as shown in FIG. Three fillers are laid in parallel on the flat plate 5 so that, for example, the horizontal pipe 6 is in the horizontal direction. At this time, the lower ends of the vertical short tubes 7 of the respective fillers are fitted into the annular pipe receiving portion 5b of the flat plate 5 and fixed so as not to move.

Thus, when the laying of the first-stage filler is completed, as shown in FIG. 7, three second-stage fillers are laid in parallel on the first-stage filler so that the horizontal pipe 6 is in the front-rear direction. The connecting projection piece 8 of the vertical short pipe 7 of the first-stage filler is inserted into the lower end of the vertical short pipe 7 of the second-stage filler, and the vertical short pipe 7 is coaxially connected up and down. Then, on this second stage filler, three third stage fillers are laid in parallel so that the horizontal pipe 6 is in the left-right direction, and the vertical short pipes 7 are connected vertically. While changing the direction of 6 alternately in the front-rear direction and the left-right direction, the packing material is piled up three by eight. When the fillers are stacked in eight stages in this way, a block-like filler aggregate having a substantially cubic shape with a side length of 1000 mm as shown in FIG. 8 is formed.
[0038]
Therefore, this packing material aggregate is arranged as a unit in a predetermined number of units corresponding to the internal volume of the rainwater storage and infiltration tank 1 in the front-rear direction and the left-right direction, and stacked in the vertical direction. The horizontal pipes 6 are connected so as not to be separated from each other as described above, and the vertical short pipes 7 of the filler aggregate that overlap vertically are connected coaxially in the manner described above to stand the straight pipe 4 in the vertical direction. Set up. And the end part of the horizontal pipe 6 of the front-back direction and the left-right direction is fitted and fixed to the said pipe receiving part 5b of the flat plate 5 attached to the inner side of the water-permeable sheet 16 of the four side surfaces of the rainwater storage penetration tank 1. The upper end of the vertical pipe 4, that is, the uppermost vertical short pipe 7 is fitted into the pipe receiving hole 5 b of the flat plate 5 attached to the upper surface of the rainwater storage and infiltration tank 1 and fixed to complete the filling operation. .
[0039]
When the filling material is filled in the rainwater storage and penetration tank 1 as described above, the flat plates 5 attached to the four side surfaces of the rainwater storage and penetration tank 1 are arranged in the longitudinal and lateral directions as described above. 6, the pressure strength in the front-rear direction and the left-right direction is increased, and a flat plate 5 attached to the upper surface of the rainwater storage and infiltration tank 1 connects the vertical short pipe 7 up and down and stands upright. Since the vertical pipe is supported from below, the pressure strength in the vertical direction is increased. Therefore, there is no concern that the rainwater storage and penetration tank 1 will collapse due to earth pressure from the surroundings, or that the rainwater storage and penetration tank 1 will be crushed from above by earth pressure or vehicle load from above. In addition, the block-shaped filler aggregate is a solid cube-shaped filling in which the horizontal pipe 6 in the front-rear and left-right directions and the vertical pipe in which the vertical short pipes 7 are connected to each other are inseparably integrated. Since it is a material aggregate, not only the pressure in the front / rear, left / right and up / down directions but also the strength against the pressure in all directions is improved overall.
[0040]
As described above, the present invention has been described by taking as an example the case where the rainwater storage and infiltration tank is filled. However, the present invention is not limited to the rainwater storage and infiltration tank, and is not limited to the rainwater storage and infiltration tank. It can be applied to various tanks.
[0041]
