Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to landscaping facilities installed in parks and the like.

BACKGROUND ART Conventionally, in landscaping facilities such as parks for recreational use, water in ponds and waterways has generally been purified by filtering and circulating it using mechanical devices powered by electricity or the like.

The present invention aims to provide an energy-saving landscaping facility that combines water purification by soil animals, soil microorganisms, plant roots, etc. in the soil and water circulation by a windmill-equipped pump.

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention, and FIG. 2 is a cross-sectional view thereof, where 1 is an upper pond, 2 is a lower pond, 3 is a soil trench connecting the two ponds 1 and 2, and 4 is a soil trench installed in the lower pond 2. A pump with a windmill that pumps water from the lower pond 2 to the upper pond,
5 is a water pipe.

Figure 3 is a cross-sectional view of a soil-type trench installed in the soil between the upper pond 1 and the lower pond 2. 6 is a permeable pipe buried in the soil, and there are many permeable holes 7 around it. It's open. 8 is sand around the permeable pipe 6, and 9 is a waterproof sheet provided below it.

The water in the upper pond 1 leaks from the permeable pipe 6 through the hole 7 into the surrounding sand 8, where it is purified by soil animals, soil microorganisms, plant roots, etc., and then purified again by the waterproof sheet 9 buried under the permeable pipe 6. It has been collected and is now flowing into Lower Pond 2.

For this reason, by making the water permeable pipe 6 meander or filling it with sand, a large resistance is given to the water flowing inside the water permeable pipe 6, and water is prevented from flowing straight through the water permeable pipe 6.

The water accumulated in the lower pond 2 begins to operate with a light breeze of, for example, 1 to 2 m/s, and when the rated wind speed is 8 to 10 m/s,
Pump 4 with a windmill that pumps water 30 to 40 minutes per second
The water is pumped up and circulated to the upper pond 1 through a water pipe 5. Note that it is possible to convey water only by wind power, or to use other power sources in combination as necessary.

In this way, according to the present invention, water is purified by microorganisms in the soil without relying on mechanical devices powered by electricity, etc., and also by using natural wind without relying on electricity or other power sources. Water can be circulated using a pump with a windmill, making it possible to save energy and have a large economic effect. Purified water can always be supplied to the lower pond, and water is purified underground between the upper and lower ponds. Since it is used for water treatment, no special chemicals are required, and it is also useful for water supply and growth of plants grown in the purification area between the upper and lower ponds.

Claims (1)

[Claims] 1. A lower pond, an upper pond, a pump with a windmill that pumps water from the lower pond to the upper pond, and the upper pond, which is surrounded by sand and has a waterproof sheet below, and which purifies the water of the upper pond and guides it to the lower pond. A landscaping facility equipped with a soil-type trench consisting of a buried permeable pipe installed in the soil between a lower pond and a lower pond.
