Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multifunctional storage which can store and infiltrate natural water such as rainwater required in a residential area or the like and can store various kinds of water or other articles. It relates to a permeation tank.

[0002]

2. Description of the Related Art Conventionally, in a large residential complex or the like, regulating ponds are provided at appropriate intervals between houses when there is sufficient land. The regulating pond digs down the ground about 1 to 2 m in a certain wide area, forms a gutter at the edge of the digging area, and connects a drain ditch from a surrounding residential area to the gutter,
Excessive rainwater, etc. in the event of heavy rain, etc., is allowed to flow into it, and water overflowing the gutters due to the inflow of a large amount of water is temporarily stored in the regulating pond. This prevents rainwater and the like from staying around.

[0003] The gutter in the regulating pond is further connected to a river or the like, the outlet of which is opened or closed as appropriate, and natural water such as rainwater is drained to the river or the like with a time lag to prevent the river from rising. It is designed to drain water. Such a regulating pond may be used as, for example, an athletic field or the like unless there is heavy rain or the like.

[0004] As another example, a storage tank is formed by digging deep into the ground, casting concrete around and at the bottom thereof, and the upper opening of the storage tank is covered with a lid supported by a concrete column or the like. is there. In the above example, as in the case of the above example, rainwater generated in the surrounding residential area and the like is caused to flow into this through a drainage ditch, and after storage for a certain time, water is sequentially discharged to a river or the like. Is what it is. The purpose is to discharge water while avoiding flooding of rivers due to heavy rainfall.

The former example is possible in an area where land is available, but is almost impossible in an area with a high land price.
The latter example is disadvantageous in that it is entirely made of concrete and is expensive. In addition, there is no action to infiltrate rainwater into the underground.

Therefore, a technique proposed to solve these problems is a storage and infiltration tank for rainwater or the like (Japanese Patent Application Publication No. 4-3 / 1994).
No. 5580). This means that "the tank is formed by digging down the ground, and in the tank, from the bottom to the vicinity of the ground line, the divisional frame divided into a plurality of divisions is vertically and horizontally and vertically connected and filled. Is a storage and infiltration tank for rainwater or the like provided with a coating means.

According to this storage / penetration tank for rainwater or the like, the rainwater or the like flows into the tank through a gutter or other drainage gutter,
The partition frame is stored in the space with a wide porosity filled with a margin. The rainwater and the like thus stored gradually penetrates into the underground with the passage of time through the periphery and the bottom of the tank, which is not sealed with concrete or the like. Thus, for example, even if a large amount of rainwater or the like flows into the tank through gutters due to concentrated torrential rain, etc., the rainwater and the like are temporarily stored in the tank and stored, and damage to roads, the neighborhood of residential land, and the like is anticipated. And, in the long run, penetrate the ground and act according to the natural cycle. In addition, since the rainwater permeates into the ground in this way, there is little overflow and the amount of water discharged to rivers and the like can be reduced. Moreover, since the storage and infiltration tank is constructed underground and can be used for various other purposes on the ground, a special large area for this purpose is not required.

The above-mentioned storage and infiltration tanks for rainwater and the like are excellent in that the above-mentioned problems can be easily solved. However, such tanks utilize the space formed underground for other uses. It cannot be done.
