Abstract

PURPOSE:To always keep soil in clean state and to completely control the supply of water by digging the ground of a lawn-laying area from the surface to a definite depth, applying a water-shielding means to the bottom and the inner side wall of the hole, laying a water-feeding pipe and circulating the discharged water after cleaning. CONSTITUTION:The field covering the whole area of the desired lawn-laying area is dug from the surface to a definite depth and the bottom and the inner side wall of the hole 1 is subjected to water-shielding treatment. Water- discharging means 3, 3a are placed on the bottom of the hole, a water-feeding pipe 4 is embedded in the ground at a definite depth and the hole is filled with soil 5 to form a circulation water channel. The water discharged from the water-discharging means is cleaned with an aeration tank 8 and supplied to the water-feeding pipe 4. The flow of the circulating water is controlled to keep the water content in the ground and to enable the control of the lawn- laying soil.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a management system for planted soil in specific areas such as golf course teeing grounds and greens where a good falling surface must be maintained throughout the year.

Conventional technology: Excessive moisture in the grass soil tends to cause rooting and pest damage; conversely, lack of moisture causes the lawn to wither. Therefore, golf courses have conventionally installed drainage means underground. In addition to improving drainage, they were kept moist by sprinkling water as needed, and fungicidal was sprayed to prevent rooting and the occurrence of pests and diseases.

C. Problems to be Solved by the Invention Although it is not easy to uniformly sprinkle water over a vast golf course, as long as proper watering is performed, there is no need to worry about tree blight. However, the only way to prevent diseases caused by pests and bacteria is to spray large amounts of insecticides and fungicides. Therefore, 7
Pollution caused by sprayed chemicals has become a problem. Also, in winter, the ground temperature often drops below freezing.
The effect of temperature drop cannot be ignored either.

2. Means for Solving the Problems The present invention is a turf soil management system that minimizes the amount of chemical spraying and ensures stable turf management throughout the four seasons, and is configured to cover the entire desired turf area. The area to be excavated is dug to a certain depth from the ground surface, the bottom and inner surface of the dug recess is water-blocked, and a drainage means is provided at the bottom of the dug recess, and a water supply vibrator is installed at a predetermined depth from the ground surface. The purpose is to dig down and backfill with soil in a concave manner, and provide a circulation waterway to purify the water drained from the drainage means and supply it to the water supply pipe, and to control the amount of circulating water and keep the amount of water retained underground at a constant level. The water supply vibrator has a large number of spout holes in the buried part, and drains water from a dug-out recess formed in a bottom surface that slopes downward relative to the drain port, and arranges the water at a position lower than the level of the drain port. Water is collected into the aeration tank, and the water purified in the aeration tank is pumped to the water supply vibrator, thereby supplying water into the soil.

E. Function The supplied purified water permeates into the soil and moistens the soil, and at the same time permeates to the bottom of the dug-out recess together with excess water such as rainwater and is discharged as wastewater. At this time, bacteria in the soil are washed away, and the soil is also constantly purified by the purified water that is repeatedly circulated, such as the discharged wastewater being purified in an aeration tank and re-supplied, and sterilized with the purified water. Water management is also perfect.

EXAMPLE A management system for planted turf soil according to the present invention will be explained based on the drawings.

Figure 1 shows the teeing ground of a golf course.The ground covering the entire teeing ground is dug to a certain depth from the ground surface and the bottom and inside surfaces of the dug-out recess are covered with mortar. A water-treated dug-out recess 1 is provided, and the bottom of the dug-out recess 1 is formed into a downward slope with respect to the drainage hole 3a. At the bottom of the dug-out recess, 10 cm to 20 cm of coarse gravel 2 is placed.
A drainage vibrator 3 is encircled within the layer of gravel 2, and the drainage vibrator 3 and the layer of gravel 2 constitute a drainage means. Also, inside the digging recess 1, a water supply vibrator 4 having a large number of ejection holes 4a is horizontally arranged at a position approximately midway between the ground surface and the gravel layer, and above the gravel layer 2, It has been backfilled with soil level 5. The drainage vibrator 3 and the water supply vibrator 4 are covered with a rough, non-corrosive cloth to prevent soil from entering. A lawn 6 is grown on the ground that has been backfilled with the soil 5. A bit 7 is dug outside the digging recess 1 at a position lower than the bottom level of the digging recess 1, and an aeration tank 8 is provided inside the bit 7. 2
Drainage from a drainage means composed of layers flows into the drainage system. A filtration device 9 is provided between the drainage hole 3a and the aeration tank 8 to collect and filter the wastewater discharged from the drainage means.
The aeration tank 8 is equipped with a drain port 10 for overflowing excess water and a water supply port 11 for replenishing insufficient water. The air pump 12 that supplies air into the aeration tank 8 is equipped with a magnetizer, and the water in the aeration tank 8 is purified and activated by magnetized air bubbles. Furthermore, the aeration tank 8 has a built-in heater 13, and can appropriately warm the temperature of the pure white water. The aeration tank 8 and the water supply vibrator 4 are connected by piping, and purified water activated in the aeration tank 8 is pumped to the water supply vibrator 4 via a pump 14.

In the management system for the planted turf soil formed in this way, for example, although not shown, a sensor for detecting water content is buried in an appropriate part of the ground, and when the water content falls below a certain value, the pump 14 is activated. If a control mechanism is provided to stop the pump 14 when the water reaches a certain value or more, when the soil dries, purified water will be sprayed out from the four spout holes 4a of the water supply vibrator by the operation of the pump 14, and the inside of the soil will become moist. When the area becomes wet, the spraying of purified water will stop. In this way, water in the soil is perfectly managed, and at the same time, the activated purified water purifies the soil and promotes the growth of the lawn. Therefore, even if you keep the spraying of insecticides and fungicides to a minimum, there is no need to worry about diseases caused by pests or bacteria.
Furthermore, in winter, by heating the purified water with the heater 13, freezing of moisture in the soil can be prevented. If more than a certain amount of wastewater, such as rainwater, flows into the aeration tank 8,
If you let it overflow from the drain port 10, and if it runs out, replenish it with tap water or the like from the water supply port 11, keep the amount of aerated water constant, and mix in fertilizer or a very small amount of chemicals as necessary, you can manage it perfectly. It becomes.

In this embodiment, the teeing ground was explained, but
For greens with undulating ground surfaces, it is desirable to place water supply pipes at the same depth from the ground surface. Furthermore, although the air pump for supplying air to the aeration unit has been described as incorporating a magnetizer, it is also possible to incorporate an ozone generating device.

G. Effects According to the present invention, the water purified by the aeration tank purifies the soil, making it difficult for pests and diseases to occur, reducing the need for chemical spraying, and reducing the need for large areas of planted turf soil to cause pollution. It can be managed without causing problems, and the practical benefits are enormous.
