一時的に貯留する雨水貯留領域として働く。2. Description of the Related Art A rainwater infiltration system is used to prevent flooding of roads, inundation of houses, flood control of rivers, return of rainwater to underground,
It is attracting attention as an effective device for preventing land subsidence, securing groundwater resources, preventing soil oxygen deficiency, preventing underground temperature rise, and replenishing water for tree planting. The conventional rainwater infiltration basin device has a structure in which gravel or the like is spread around a rainwater infiltration basin buried in the ground. Innumerable voids generated between the gravel particles are formed around the rainwater infiltration basin, and the entire voids serve as a rainwater storage region for temporarily storing rainwater.

し易い。However, the above-mentioned conventional rainwater infiltration basin has the following problems. (A) The rainwater storage capacity of the gravel is determined by the voids formed between the gravel particles. However, the voids per unit volume in the rainwater storage area are extremely small. Moreover, even if the size of the gravel particles is selected, the size and number of the voids cannot be increased so much. Therefore, sufficient rainwater storage capacity cannot be secured. (B) In order to form a rainwater storage area around the rainwater infiltration basin, it is necessary to transport and embed heavy gravel, which imposes a heavy burden on workers and also deteriorates workability. Become. (C) The rainwater storage area due to gravel shrinks due to the dense gravel that occurs over time and the resulting reduction in voids. For this reason, it is easy to cause ground subsidence over time.
