DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water storage type soil system having a water level adjusting function, and more specifically, it is suitable for each of the following cases. 1. Pavement system for lawn cultivation. 2. Pavement system in grounds, plazas, parks, etc. 3. Pavement system for petals and vegetables.

[0002]

2. Description of the Related Art Heretofore, this type is as follows. 1. Soil moisture control depends on rainfall and watering. 2. When there is a large amount of rainfall or water sprinkling, it is infiltrated underground. 3. When the surface is dry, sprinkle water artificially.

[0003]

The above-mentioned prior art has the following problems. The water content of the soil can only be relied on by rainfall and watering, and when the soil becomes saturated, it becomes gravity water and permeates into the underground. The surface quickly dries up and grows suitable lawns, clay-based grounds, and open spaces. A lot of labor and water was required for the maintenance and management. The present application has been made in view of such problems of the conventional technology, and the purpose thereof is to:
It seeks to provide something that can: 1. Since the amount of water sprinkled is saved by the effective use of water resources, and because it is a water storage type with an impermeable sheet, natural rainfall and sprinkling water are not missed. 2. The time and effort required for watering can be reduced. 3. The water-blocking sheet can prevent underground penetration of pesticides and fertilizers. 4. Appropriate soil moisture for vegetation can be adjusted. 5. The initial curing of the lawn can be simplified. A large amount of watering is necessary for germination of the lawn, but by raising the water level by adjusting the water level, the soil water content is sufficient and there is no need for watering, and no seed runoff occurs. 6. It can hold clay-based ground, the dustproof effect of plaza, and moderate hardness.

Are connected. In this case, the structure of the water level adjusting basin 9 and the structure of the water collecting basin 10 or the structure of the water level adjusting basin 11 are the same as the water level adjusting basin 9 in the water storage type soil system 1 having the water level adjusting function in the clay pavement zone of the first invention. The configuration of
Also, the structure is the same as that of the water collecting tank 10 or the water level adjusting tank 11.

[0012]

Since the present invention is configured as described above, it has the following effects. 1. In the clay pavement or lawn pavement, a water-blocking sheet is used as a water storage type to collect natural rainfall and sprinkling water underground without permeating the water through the underdrain pipe laid on the water-blocking sheet, and at the end of each block. The water level can be adjusted according to the purpose by adjusting the water level using a water level adjusting basin having a water level adjusting function. 2. The following effects can be expected in a lawn pavement belt. A. Initial curing period of lawn In the sowing period of lawn, as shown in Fig. 4, water is sucked up by the capillarity in the voids of sand by adjusting the water level by lowering the mouth of the hoisting pipe by about 15 cm from the lawn, so that the lawn is sucked up. Can supply water to the roots. B. High growth period of lawn During the high growth period of growth of grass, as shown in FIG. 5, the grass roots extend about 15 cm to 20 cm. 9 from the lawn
By lowering the water level by about 15 cm to 15 cm, the water content can be sucked up by the capillarity in the voids of the lower layer material (volcanic gravel) and sand, and the water content can be supplied to the turf root. C. Lawn growth failure period During lawn growth failure period (when the lawn growth limit temperature is exceeded), drain the water from the pavement with the hoist of the hoisting pipe at the lowest position as shown in Fig. 6. As a result, the following effects can be achieved. a. It is possible to improve the lawn growth effect by keeping the lawn soil moisture. b. It is possible to maintain the dustproof effect due to the water retention of the ground soil and an appropriate hardness. c. Effective use of water resources and watering work can be reduced by reducing the amount of watering the lawn. d. It is possible to prevent underground penetration of pesticides and fertilizers and save labor. e. Because of its water storage capacity, flood control is possible. 3. The effects of the overflow unit 14 are as follows. When adjusting the water level, it is necessary to prevent the water from overflowing from the lid when water that exceeds the drainage capacity flows into the water level adjusting basin at the mouth due to heavy rain. In addition, when adjusting the water level, if long rain continues and you want to adjust the water level to the lowest level, you can drain the stored water by opening the valve without turning the handle. In addition, when regaining the regulation function, the previous water level can be maintained by closing the valve.
