Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for watering and draining surface vegetation such as lawns on golf courses and the like.

For lawns, especially lawns such as golf course greens, there are restrictions on watering time due to constraints such as weather conditions, working hours, and playing hours. In other words, when the grass is dry at high temperatures such as in summer, the water content is insufficient and the lawn tends to dry out, so if water is watered without limit, it will cause sunburn. Also, if the humidity is too high, pests and diseases will occur.

Irrigation in the winter also tends to cause frozen soil, which can freeze and damage the lawn, causing frost and withering.

Furthermore, when watering lawn areas such as turf with sprinklers, the water that is sprinkled flows over the surface and does not penetrate into the ground.

The present invention has been made in view of the above-mentioned drawbacks, and its purpose is to provide the necessary and appropriate amount of water for supplying water within the top soil and draining water from the top soil, etc., especially on sloped areas, without being restricted by the watering time. The object of the present invention is to provide a water supply and drainage method for ground plants such as grass grown on the ground surface, which enables water to be secured and water management to be carried out artificially.

Hereinafter, a case in which a golf course is constructed will be described as an example according to FIGS. 1 to 3.

In the first step, the sloped ground surface H is excavated to a predetermined depth D to form a base surface B whose longitudinal section is substantially parallel to the ground surface H.

Depth D is 50cm from the ground surface H, i.e. the green surface.
It is desirable to excavate forward and backward. Excavation will be carried out using bulldozers, lift trucks, etc., and the excavated soil will be transported to the designated area by vehicle. The B side of the foundation will be leveled using bulldozers, etc.

In the second step, partition plates 1 are erected in steps along a plurality of contour lines on the surface B of the substrate formed in the previous step.

The partition plate 1 has a width of about 40 cm or less and a length of about 50 m, and is cut to a length suitable for the site and erected vertically in the width direction.

In the third step, a water-impermeable sheet 2 is laid over the entire surface of the base B on which the partition plates 1 were erected in steps in the previous step. The material used for the sheet 2 is polyethylene, vinyl, or the like.

In the fourth step, the sheet 2 is placed on the high side of the sheet 2 at the part intersecting with the base B surface across the partition plates 1 laid down in the previous step, that is, on the slope partitioned by the partition plates 1. A water collecting pipe 3 with a small hole is arranged at a low position of the part, and one end 3a thereof faces a pit 4 for water collection and water transition adjustment. This pit 4 is constructed of concrete. Reference numeral 5 denotes a vertical pipe disposed vertically within this pit 4, and this vertical pipe 5 is connected to the water collecting pipe 3. Further, in order to adjust the underground water level, this vertical pipe 5 is provided with a plurality of holes (not shown) above and below that can be opened and closed freely.

In the fifth step, sand 6 of a predetermined viscosity is poured onto the base B surface on which the sheet 2 was laid in the previous step and the water collection pipe 3 was arranged.

In the sixth step, topsoil 7 for vegetation is layered on the top surface of the sand 6 soiled in the previous step so as to be substantially aligned with the original ground surface H, and surface vegetation such as grass is planted. The thickness of the topsoil 7 for vegetation is sufficient to cover and grow the roots of surface plants such as lawns, and for example, about 5 to 15 cm is sufficient.

In the seventh step, the ground surface on the low side above the sloped base B with the partition plate 1 in between, that is, the partition plate 1,
Topsoil 7 for vegetation at high positions on the slope section divided by 1 is sporadically removed using a hole cutter (not shown) to form circular holes 8. The depth of this circular hole 8 is about 20 cm and the diameter is about 10 cm.

Then, a water sprinkling nozzle 10 having a cylindrical insertion portion 10A connected to a water supply member such as a hose 9 at one end and having a water sprinkling portion 10B formed of a wire mesh is inserted into the circular hole 8.
Water is supplied by inserting it into the tank. At this time, the amount of water supplied is adjusted by a valve provided on a water supply member or the like. Water is supplied in this way, but after water is supplied, if necessary, the watering nozzle 10 is removed from the circular hole 8, and the circular hole 8 is backfilled with topsoil for vegetation 7, which was extracted using a hole cutter as described above. The ground surface may be restored using

One embodiment of the present invention has the above-mentioned configuration, and excessive moisture in the topsoil 7 for vegetation is collected in the water collection pipe 3 and drained from the pit 4 for water collection and water level adjustment. Further, the amount of drainage is controlled by the pit 4. Therefore, root rot of the grass grown on the topsoil 7 for vegetation and damage from pests and diseases do not occur.

In addition, water is not supplied from the surface of the topsoil 7 for vegetation, but rather by inserting one end of the topsoil 7 into circular holes 8 from which the topsoil 7 has been sporadically removed using a hole cutter (not shown) using a water supply member such as a hose. Water is supplied by inserting the cylindrical insertion part 10A of the water spray nozzle 10, which is connected to the cylindrical insertion part 10A and has a water sprinkling part 10B formed of a wire mesh in the cylindrical insertion part 10A. When water is supplied in this way, the water permeates into the topsoil 7 for vegetation by capillary action. The amount of water supplied can be controlled by a valve provided on a water supply member such as a hose.

Therefore, even during hot and dry times such as summer, the moisture content of the sand 6 and the vegetation topsoil 7 on top of it will not become insufficient, and the appropriate amount of moisture can be supplied to the lawn without being constrained by weather conditions, working hours, or playing hours. can. Therefore, it is possible to prevent the lawn from getting sunburnt in the summer and the occurrence of pests and diseases, and also to prevent frost damage in the winter.

Although the above embodiments have been described with reference to the case where water is supplied to surface vegetation such as lawns, the present invention can also be applied to the management of fertilization by supplying liquid fertilizer instead of water.

As described above, according to the present invention, it is possible to supply water within the top soil and drain water from the top soil as needed, especially on sloped land, without being restricted by weather conditions such as summer or winter, or watering time during work or play. Water management can be done artificially by making it possible to secure a sufficient amount of water. Therefore, there is no difference in moisture content in the top soil such as topsoil for vegetation throughout the year, and the appropriate amount of water and fertilizer can be supplied, making it suitable for the growth of surface vegetation such as grass that grows on the ground surface. .
