(Conventional technology) Conventionally, the purpose of sewerage systems has been to quickly remove sewage and rainwater, but speeding up the removal of rainwater leads to temporal concentration of mountain water runoff and increases the maximum runoff area of rivers. Enlarge. However, it is extremely difficult to increase the communication capacity of rivers in a short period of time.

Therefore, rainwater from plazas, residential development areas, etc. is not immediately drained away, but is temporarily retained in storage tanks and allowed to permeate underground.

(Problems to be Solved by the Invention) In the storage infiltration system as described above, the rainwater is collected into a roadside groove or an underground U-shaped groove with a sloped surface and is then guided to a storage tank. ing. The present invention provides a water storage and infiltration system that eliminates the need for such a structure, and in which water does not flow over the surface even in the event of heavy rainfall, and water often overflows from the grooves.

A porosity of 070 and a porosity of 50 to 80% can be obtained in the latter case. Although the shape of the entire storage tank is not particularly limited, it may be arranged in a grid pattern 4, for example, as shown in a plan view in FIG. Figure 1 is I of Figure 2.
Corresponds to the cross section on the -1' plane. The size of the storage gI tank can be, for example, 0.5 to 2 m in height, 1 m in width, and 1.5 to 2 m in interval in FIG. 1. Repeat this pattern as many times as necessary.

In addition, a curbstone 6 is optionally provided at the edge of the square, so that when an extremely large amount of water comes out, water can temporarily accumulate on this approximate surface.
It can then be allowed to seep through the permeable concrete over time. However, if the permeable concrete has a large permeability coefficient, such a curb is not necessarily required.

(Function) In the present invention, water directly and quickly permeates the road surface, passes through the crushed stone roadbed, and diffuses into the storage tank or into the soil at locations where there is no storage tank below.

Therefore, there is no need to slope the road surface and provide L-shaped grooves, U-shaped grooves, etc., and water does not remain on the road surface or flow because water permeates quickly. In addition, the entire road surface is permeable, so
Water expands into the soil where there is no reservoir, resulting in a higher overall water infiltration capacity than traditional systems.
