It is arranged so as to be juxtaposed in parallel to the position where it is located.

Then, the side bottom portion 16 of the side column 12 and the column
Continuously on the upper surface of the bottom 26 of the thirteen, while embedding the reinforcing rods 18 protruding from the side bottom 16 and the bottom 26 on one side, using a non-shrinkable concrete, concrete-casting the site at the bottom of the passage.
Form 35. Thereafter, the lid 14 is placed on the mounting surface 19 of the side column 12 and the column 13 on the positioning portion of the mounting portion 20 of the column 13.
Position it in the longitudinal direction between 29 and 29 and place it.

Further, a filler is poured into the opposing notches 33 between the lids 14 and 14 facing each other via the positioning portion 29 and on both sides in the longitudinal direction of the lids 14 and 14, so that the main body 11 of the retarding basin device is played. A water pond space 36 is formed to form a box.

The main body 11 of the retarding pond device is a retarding pond space.
Rainwater or the like flows into the inlet 36 from an inflow port (not shown) and is temporarily stored, and is sequentially discharged from a drain port (not shown).

According to the above embodiment, a passage bottom 35 is formed between the bottoms 26, 26 of the column 13 which has hitherto abutted by concrete in-situ, so that the bottom surface of the main body 11 of the retarding pond device has no gap. This prevents water from penetrating from the base surface due to the gap and permeation of the rainwater and the like stored in the retarding reservoir space 36 to the base surface. Therefore, for example, when the retarding basin device main body 11 is installed on a hill, it is possible to prevent the rainwater stored in the retarding reservoir space 36 from overflowing from the base surface to the lowland again through the basement, and the installation place is limited. Moreover, the capacity of the retarding basin space 36 can be used efficiently, and the management of rainwater in the retarding basin space 36 can be facilitated.

Further, the filler is poured into the lid 14 between the opposed longitudinal ends via the positioning portion 29 and between the opposed notches 33 on both sides in the longitudinal direction, and is integrally connected flush. Therefore, the structural strength of the retarding basin device main body 11 can be improved.
