Abstract

PURPOSE:To facilitate control by laying a non-water permeable sheet on the foundation and, at the same time, erecting form stops, providing water collecting means connecting a water collecting pit to one end of each of them to a high-place side, and providing water spray nozzles connecting to a water supply source to a low-place side. CONSTITUTION:Form stops 1 are erected along a plurality of contour lines on the excavated foundation B and, at the same time, a non-water permeable sheet 2 is laid thereon. After that, water collecting pipes 3 are arranged on the sheet 2 of a high-place side across the form stops 1, and one end of each of them is connected to a water collecting and water-level controlling pit 4. Then, after sand 6 having a specific particle size is brought on the foundation B from another place, surface soil 7 for vegetation is layered to plant, and water spray nozzles 10 connecting to feed members are inserted into circular holes 8 formed on high positions of the low- place sides of the form stops 1. Excessive water contained in the surface soil 7 is collected to the pipes 3 to drain off from the pit 4 and, at the same time, it is so constituted that water is supplied from the nozzles 10. Accordingly, water supply and drain can be easily controlled.

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

Furthermore, when sprinklers are used to water lawn areas such as turf, 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 purpose of the present invention is to provide a water supply and drainage method for ground plants such as grass grown on the ground surface, by which water can be managed artificially by making it possible to secure moisture.

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

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.

The depth D is preferably about 50 cm from the ground surface H1, that is, the green surface. Excavation will be carried out using bulldozers, lift trucks, etc., and the excavated soil will be transported to the designated area by vehicle. The JIIB surface will then be leveled using bulldozers, etc.

In the second step, the partition plates 1 are erected in steps along a plurality of contour lines on the 8 surfaces of the base plate formed in the previous step.

Partition plate 1 is approximately 40cm or less in width and length! The length of fJ50m is cut to a length that suits the site and is erected perpendicularly to the r11 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 2 sides of the sheet 2 on the high side of the part intersecting with the 8 sides of the base across each partition plate 1 laid in the previous process, that is, on the slope partitioned by the partition plates 1. A water collection pipe 3 with pores is disposed at a low position of the part, and one end 3a thereof faces a bit 4 for water collection and water level adjustment. This bit 4 is constructed of concrete. Reference numeral 5 denotes a vertical pipe disposed vertically within this bit 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, the sheet 2 was laid in the previous step and the water collection pipe 3
Sand 6 of a predetermined grain size is poured onto the surface of the base 8 on which the sand 6 is placed.

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 vegetation such as lawns, and for example, about 5 to 15 cm is sufficient.

In the seventh step, topsoil for vegetation 7 is cut with a hole cutter (Fig. (not shown) to form circular holes 8. The depth of this circular hole 8 is about 20 cm and the diameter is about IQ.
It is about cm.

Water is supplied by inserting into the circular hole 8 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. 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 manner, 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 has been extracted using a hole cutter as described above. The ground surface may be restored.

One embodiment of the present invention has the above-described configuration, and excessive moisture in the topsoil for vegetation 7 is collected in the water collection pipe 3 and drained from the bit 4 for water collection and water level adjustment.

Further, the amount of drainage is controlled by bit 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, the topsoil 7 for vegetation is sporadically extracted using a hole cutter (not shown) into circular holes 8, and the negative end is connected to a water supply member such as a hose. 10A of the cylindrical insertion part of the water sprinkling 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.
Insert and supply water. 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 high temperature and dry times such as summer, the moisture content of the sand 6 and the topsoil 7 for vegetation on its upper surface will not be insufficient, and the weather conditions
An appropriate amount of water can be supplied to the lawn without being restricted by working hours or playing hours. 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. There is no difference in the moisture content in the soil such as topsoil for vegetation throughout the year, and it is suitable for growing surface vegetation such as grass on the ground surface by supplying the necessary amount of water and fertilizing.
