る。[Prior Art] Conventionally, as shown in FIG. 2, drainage of a golf course green is performed by a drainage pipe (10) embedded in the green. As the drain pipe (10), a pipe made of synthetic resin or a biscuit pipe having a large number of holes formed in its side wall is used. The diameter of the drainage pipe (10) varies depending on the rainfall amount and the area of the green, but generally the branch pipe (10a) has a diameter of about 5 to 10 cmφ, and the main pipe (10b) has a diameter of about 10 to 15 cmφ. Then, the rainwater that permeates the green and enters the drainage pipe (10) through the holes on the side wall is collected in the main pipe (10b) and is concentratedly drained from one or two places.

環境汚染の原因となっていた。[Problems to be Solved by the Invention] However, most of the current greens are sandy greens that use a large amount of sand to prevent root rot of turf. Even if it rained, it immediately penetrated the sand layer and was drained. The pesticides and fertilizers used to maintain and manage the turf also flowed out with this rain, causing environmental pollution in the downstream region.

てもよい。In FIG. 1, (1) is a water reservoir filled in a pan-shaped recess (2). The recess (2) is formed so that the center part becomes a flat fence corresponding to the shape of the green, and the depth is more than the depth of the hole cup, but it is usually about 30 to 50 cm. . The reservoir (1) filled in the depression (2) stores rainwater and irrigated water and also decomposes fertilizers and pesticides, so that even if some rain falls, the rainwater immediately falls. It is prevented from flowing into the basin, and the degradation of drugs etc. by microorganisms reduces the outflow to the outside. In addition, it is possible to reduce the frequency of irrigation by using the water accumulated in the reservoir (1). Reservoir (1) is crushed stone or concrete to about 3-4 cm, sand, jam (natural cobblestone)
Etc. can be configured. If necessary, a drainage pipe (not shown) may be provided on the water storage layer (1).

を用いるのが好ましい。On the sand layer (3), the diatomaceous earth is fired at a high temperature of about 1100 to 1200 ° C. to form the improving material layer (4) containing the soil improving material which is made into ceramic. The ceramic soil improver layer has a porous structure having a large number of fine pores, and is therefore characterized by being extremely excellent in water permeability, water retention and fertilization. The soil conditioner has a columnar shape (for example, a diameter of about 1 mm and a length of about 3 mm) that is more likely to be caught on the grass than a spherical shape so as to prevent the soil from disappearing due to movement.
Is preferably used.

The water absorbing part (5) is composed of the above-described ceramicized soil improving material, plays a role of a kind of passage for guiding the water stored in the water storage layer (1) to the improving material layer (4), The water absorption can be further enhanced. The cross-sectional area of the water absorption part (5) is usually 70-200 cm 2
It is / 1 place, and it is preferable to form it at a ratio of 1 place every 3 to 4 m 2 .
