本発明は、雨水及び汚水°等のための水貯留浸透システ
ムに関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to water storage and infiltration systems for rainwater, sewage, etc.

を目的とされていたが、雨水の排除を早めることは、山
水流出の時間的集中化をもたらし、河川の最大流出址を
大きくする。しかし、河川の疎通能力を短期間に増大さ
せることは、極めて困難である。(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.
そこで、広場、宅地造成地域などからの雨水を直ちに流
出させないで、貯留槽に一時滞留させ、地下に浸透させ
ることが行われている。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.

れることが々い、水貯留浸透システムを提供する。(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.

It is preferable that it is 2 or more. The thickness of the permeable concrete layer is determined by its strength and expected loads;
Generally, it is 8 to 20 units.

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.
第2図に示すように、各貯留槽部分の中央に有孔管5が

孔管である。The height at which the perforated pipe is installed can usually be near the center of the reservoir. For example, the perforated pipe has a diameter of 150 to 20
It is a perforated pipe made of polyvinyl chloride, and has holes of about 20 diameters spaced at intervals of several to several tens.

が大きい場合、かかる縁石は必ずしも要しない。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.

(作用)
本願発明において、水は直接に路面を迅速に浸透し、砕
石路盤を通って貯留槽にあるいは貯留槽が下方にない個
所では土中に拡散してゆく。(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.
従って、路面に勾配を付け、L形溝、U形溝などを設け
る必要がなく、かつ迅速な透水の故に路面に水が残った
り、流れることがない。また路面全体が透水性なので、
貯留槽がない個所でも水が土中に拡張してゆき、この結
果、全体としての水の浸透容量が従来のシステムよりも
犬である。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.
