6, and replenishing means 3, 1 for replenishing water in the storage tanks 1, 11.
And 7 are provided.

The storage tank 1 is, as shown in FIGS. 1 to 3,
It is formed into a hollow, almost sealed box,
For example, by being surrounded by bottom side walls, left and right side walls, front and rear side walls, and an upper side wall, it has a substantially rectangular parallelepiped shape elongated along the vegetation surface E, and is directly framed at the installation site, or has an appropriate size. For example, the block bodies formed in a U-shaped groove-shaped unit are connected to each other at the installation site.

The water supply member 2 is formed of a water-permeable natural stone into a columnar shape having a rectangular cross section, for example. It absorbs water and supplies it to the soil on the vegetation surface E above the storage tank 1. That is, the water supply member 2
The material used for forming has a large number of continuous water-absorbing pores that cause capillary action. Even if a rough stone is quarried and formed into a predetermined shape, the water-absorbing pores exposed on the entire surface of the reservoir 1 The water infiltrates into the inside, is sucked up, and leaks out to the outside, thereby moistening the soil content outside the storage tank 1. The natural stone material as the water supply member 2 used in the present invention is produced, for example, in Indonesia, India, etc., and is formed into a predetermined shape after quarrying, and has a rectangular cross section as shown in the drawing. However, it is possible to change to various shapes such as circular, half-moon shape, gear shape, etc.Also, by considering the shape of the insertion part on the upper side wall so that it can be supported without rattling I am doing it.

The replenishing means 3 is formed in, for example, an L-shaped tubular shape connected to one of the side wall portions of the storage tank 1 as shown in the drawing, and the replenishing port 4 of the replenishing means 4 is exposed on the ground surface of the vegetation surface E, for example. And is covered by an appropriate opening / closing lid.

In the embodiment shown in FIGS. 4 and 5,
It is designed to be suitable for installation on the vegetation surface E of a sloping land. A plurality of overflow basins 12 are arranged adjacent to each other by setting a step corresponding to the slope, and the upper and lower tiers of the front and rear overflow basins 12 are arranged together. The overflow tank 13 formed on the upper side of the front side wall of the side overflow basin 12 is caused to flow into the inflow section 14 formed on the upper side wall of the overflow basin 12 on the lower stage side, whereby the storage tank 11 having the step structure is formed. A permeable structure which is constructed, the lid member 15 is laid across the upper edges of the respective overflow basins 12, and the lid member 15 is inserted to project from the inside of the overflow basin 12 into the ground of the vegetation surface E above the lid member 15. A natural water supply member 16 made of natural stone is provided, and at least the uppermost overflow basin 12 is provided with a replenishing means 17 for replenishing water in the storage tank 11.

Each overflow basin 12 constituting the storage tank 11
Are formed by being surrounded by the bottom side wall, the left and right side walls, the front and rear side walls, and the upper side wall, and each of them is independently framed and continuously arranged at the installation site, or a plurality of them are continuously formed. The overflow basin 12 is integrally formed or provided. In the figure, the overflow portion 13 is formed in a hole shape or a groove shape in the upper part of the front side wall of the overflow basin 12 itself, and the inflow portion 1
4 is formed in the shape of a hole in the upper side wall of the overflow basin 12 itself in the vicinity of the upper side overflow basin 12 respectively, but by removing and opening the upper side wall of the lower spillway 12 The formation of the inflow part 14 can be omitted, and the overflow part 13 and the inflow part 14 can be directly connected by a pipe or the like. In this case, the lid member 15 can be omitted. In short, it is sufficient that the overflow water from the upper overflow basin 12 flows into the lower overflow basin 12 and that a predetermined amount of water is stored in each overflow basin 12. It is a thing. It should be noted that the overflow basin 12 itself is formed to be long in the installation direction when the inclination at the installation location is gentle, and short in the installation direction when the inclination is steep.

The cover member 15 prevents the soil content on the vegetation surface E from falling into the overflow basin 12 and is omitted when the overflow path has a closed structure as described above. Sometimes.

Since the water supply member 16 and the replenishing means 17 are constructed in the same manner as in the previous embodiment, detailed description thereof will be omitted, but one is provided at the stepped portion obtained for each overflow basin 12. Not only the water supply member 16 but also a plurality of water supply members 16 can be arranged. The replenishment means 17 is not limited to the case where the replenishment means 17 is attached to the uppermost overflow basin 12 and is additionally attached to any portion on the way. It is also possible.

Next, an example of installation and use of the device of the present invention will be explained. For example, when a vegetation surface E is formed on a median strip, a roadside strip, etc. on an expressway, it is installed in the ground, and on a flat ground. In some cases, as shown in FIGS. 2 and 3,
When it is a sloping ground, it is installed as shown in FIGS. Then, water is supplied from the replenishing port 4 of the replenishing means 3 and 17 exposed on the surface of the vegetation surface E to store the water in the storage tanks 1 and 11 in a filled state, and by the capillary phenomenon of the water supply members 2 and 16, the storage tanks. The water in 1 and 11 is sucked up, and the soil content of the vegetation surface E is kept in a wet state at all times.

[0020]

The present invention is configured as described above.
Therefore, even if the soil on the vegetation surface E does not have sufficient water retention capacity, the water in the storage tanks 1 and 11 is constantly supplied to the vegetation surface E, so that water for various vegetation plants is It does not die even in the dry season, and it is extremely easy to replenish the consumed water.
Since it emits little radiation, it can be used without waste.

That is, this is the storage tanks 1 and 11 and the storage tanks 1 and 11 buried in the ground of the vegetation surface E in the present invention.
A water-supplying member 2, 16 made of a water-permeable natural stone projecting into the ground of the vegetation surface E above the storage tanks 1, 11 and replenishing means 3, 17 for supplying water into the storage tanks 1, 11. The reason for this is that the wet state of the soil content suitable for the growth environment of various vines and shrubs on the vegetation surface E can be always ensured by this.

Further, when the water in the storage tanks 1 and 11 is consumed by sucking up the water supply members 2 and 16, the water can be replenished and supplied through the open replenishing means 3 and 17, and at the time of replenishing, the surroundings can be supplied. Since the water is not sprinkled onto the vegetation surface E, the storage tanks 1 and 11 can be filled with the waste material without waste, and the soil on the vegetation surface E can be stably supplied and wetted.

On the other hand, when the vegetation surface E is inclined, a plurality of overflow basins 12 set corresponding to the inclination can be arranged adjacent to each other in the front and rear to form the storage tank 11 having a step structure.
By the water supply member 16 which is inserted and arranged in each of the overflow basins 12, the soil content in the vegetation surface E area divided for each step can be moistened, and the vegetation surface E area is dried regardless of the upper or lower side. There is no such thing.

Further, between the front and rear overflow basins 12 in the storage tank 11 having the step structure, an overflow path for allowing the overflow water from the overflow basin 12 on the upper stage side to flow into the overflow basin 12 on the lower stage side, for example, the overflow water on the upper stage side. Overflow part 1 formed on the upper front wall of the masu 12
Since the overflow water from No. 3 is made to flow into the inflow portion 14 formed on the upper side wall of the overflow basin 12 on the lower stage side, if the water is supplied to the overflow basin 12 on the upper stage side, the overflow water on the lower stage side is sequentially overflowed. It is possible to overflow into the cells 12 and fill each of the overflow cells 12 with each other.

Further, the device of the present invention can be used not only as the median strip and roadside strips on the expressway as described above, but also as an irrigation facility for planting pots, further farmland, and greening of deserts. By supplying hot water in place of water, it can be used as a multi-purpose item for increasing the temperature of geothermal heat.
