Description

Detailed Description of the Invention (Industrial Application Field) The present invention can be used for mochi-sho, etc. immediately after rainfall or sudden sprinkling of water, and can also be used for sports where turfgrass can be grown even under severe treading pressure. This relates to the construction method of fields, and sports fields include, for example, golf courses, playing fields, baseball, soccer, lawn tennis, etc., as well as school fields, etc.
It is primarily used for streets, schoolyards, park plazas, lawns, walkways, etc.

4. Although the problem with natural grass living and grounds can be eliminated, it is difficult to maintain the grass that creates the surface. The common cause of these problems is that the water that seeps into the ground is excessively retained, and the non-capillary pores that serve as passageways for water disappear due to the treading pressure caused by play, and the roots of the turf grass are in an oxygen-deficient state and potash, and the ground quickly becomes bare. become The excess water associated with these needs to be removed as soon as possible, and there are no sufficient solutions to solve these problems.

(Means and effects to be solved by the invention) As a result of various dim lighting and μ cultivation, the present invention covers the soil base γ waterproof synthetic covering as an underground sakaki stage, prevents water from flowing onto the base, and A multi-purpose perforated pipe 7 is arranged on the upper part as a pipe 7 for drafting and water extraction, and porous natural pumice grains or artificial porous transport aggregate are used as a permeation drainage layer on the upper part. Therefore, it is possible to provide an underground environment with good ventilation, drainage, and water retention, and if turfgrass is planted, strong turfgrass will grow, providing a natural turf sports field that can withstand tread pressure.

(Example) The total Jl+ of the present invention will be explained below with reference to the drawings.

FIG. 1 is a sectional view of a golf green according to the present invention. Although the digging depth varies depending on the height Kj of the finished surface, it is determined by the base layer 1t, and grooves are dug at intervals of, for example, 4 m to form ventilation and drainage V grooves 2. A synthetic chemical product sheet with a thickness of 0.5 to 1.5 thick is closely laid on the base layer 1 and the bottom of the air-permeable drainage groove 20 to form a waterproof mat 3. Ventilation and drain pipes have a diameter of 60 to 10
Insert the 0n multi-purpose perforated pipe 4 and the 0 layer 5 and 2 above it.

to a thickness of 100 mL to form a rapid drainage layer. A net or fibrous mat is laid above it to form a filter tank 6 to prevent small particles from flowing into C-5.

That soil soup? Pumice sand or artificial porous aggregate with a diameter of 2 to 5 mm and a thickness of 20 to 25 α is poured into A#7. The water permeability rate of this person, 7, is more than 1000 iris/hour, forming a mist-like pine air system that grows in the air layer.

Immediately put cypress shoulder-like goose and retaining material in the 3rd layer of KIO and put 10 c.
Cultivate 1 layer to a depth of about TIL to create a surface layer. The A fat 70 coating layer forms the entire initial culture bed of turfgrass, and its water permeability rate is 5.
00~1000m/hour? When planting Ichishiba Midori to finish it on the golf green surface, a layer of 2-5α toab soil 8 is formed by adding soil several times before finishing it on the surface of the golf green, so the batting quality is maintained and the stability of kWz+ is maintained. The water permeability of Ippon Toku 1 Soil RVI s is 3
00 fi/hour or more is better, and to avoid thickening of the layer over time, tie khK Negura's fgT vertically.

These top soils 8 to 5: By being constructed in accordance with the above specifications, the gaps between the particles are conducive to gravity water flow, and water does not stagnate underground. On the other hand, due to the pores of pumice or artificial porous aggregate, it can be used for the cultivation of artificial water, Ibishi, and 2 reeds. Because porous aggregate is used, firstly, there is no limit to the use of the field or surface due to excess moisture, and it is always possible to play in good condition.Secondly, the underground pongee hardening due to excess moisture. , oxygen deficiency is avoided, the main force of Shibakarasu is promoted, and the putting quality is always maintained.
A good cork green color was formed.
