Abstract

A sports ground, including a base with slopes from the central longitudinal axis, on which the soil vegetation layer is laid, and on the inside there is a side and a pipe closed by a grate for water drainage and a pipe for supplying warm air, and at the base of the side on the inside a groove is made in the box, characterized in that supports and lattices are laid on the bottom of the box, and a crushed stone layer 50-100 mm high, a pebble layer 50-100 mm high and a soil layer are placed on top of the box, and reservoirs for rain accumulation are installed under the box bottom water and for further irrigation of the root system.

Description

The proposed utility model relates to the construction of sports facilities, football fields, rugby fields, tennis courts used for sports on natural grass, for arenas under the roof and also in agriculture.

Known sports ground (1), including soil-cover, water-retaining and subsoil layers, a layer of crushed stone, a drainage device made of a pipe system and a base. The site is additionally equipped with a layer of expanded clay. The moisture-retaining and subsoil layers are made with a porosity of 45-47%, and the drainage device contains perforated pipes laid in parallel layers along the site in the rubble layer. The air inlet pipes with plugged ends are located at the ends of the perforated pipes, and the outlet vertical pipes are connected to the air inlets and have an outlet at the level of the surface of the soil layer of the site.

The disadvantage of this technical solution is that keeping the sports lawn even, able to tolerate frequent mowing, and being resistant to adverse conditions is very difficult throughout the entire sports season, since a layer of gravel and pebbles makes it difficult for air to pass through this layer for normal grass growth.

A well-known sports ground (2), including a base with two slopes from the central longitudinal axis, on which a drainage layer and soil drainage layer are laid. On the base, which is part of the box, on the inside there is a side and a pipe with a grill for water drainage and a pipe for supplying warm air is installed, and a groove is made at the base of the side on the inside of the box. Box and side are made of concrete. The side has a height of at least 35 cm.

The disadvantage of this technical solution is the insufficient effect on the groundwater level and insufficient effect on the drying process of the soil.

The objective of the proposed technical solution is the device of such a platform that would meet all the necessary requirements: uniformity and the same layer thickness. The soil should absorb water well and let air through.

The problem is solved by constructive study of the sealed box, which prevents the penetration of rain and melt water into the lawn. At the bottom of the box, supports are provided for the grilles, and a layer of crushed stone 50-100 mm high and a pebble layer 50-100 mm high are laid on the grilles. then a layer of soil is poured. A groove and a pipe for draining water are laid at the base of the inner rim on the inside of the box. A pipe for supplying air from the compressor is connected to the base of the inner side of the inner flange. Under the sealed box bottom there are reservoirs for accumulating water after heavy rains for further irrigation of plant roots, if necessary.

This technical result is achieved in that the basis of the entire claimed invention is a sealed box (Figure 1). the outer perimeter of the rectangle is the wall of the box, (Figure 2 (1)), the inner perimeter is the inner rim of Figure 2 (2). The walls and bottom of the box prevent rain and meltwater from entering the perimeter of the sports lawn, which is a very important factor. The inner rim of FIG. 2 (2) prevents the penetration of air pumped by the compressor under pressure out of the zone B of FIG. 2, directing it strictly upward (white arrows in FIG. 2).

An example of creating the proposed sports field is shown in (Figure 2.). Section AA.

The bottom of the box is made sloping (in Fig.2 a slope from right to left). At the bottom of the box, the supports of FIG. 2 (3) are laid under the grilles of FIG. 2 (4). On the laid lattices of Figure 3, a layer of crushed stone of Figure 2 (5) with a height of 50-100 mm and pebbles of Figure 2 (6) with a height of 50-100 mm are laid. Then a soil layer of Figure 2 (7) is poured. At the base of the inner rim of FIG. 2 (2), a groove of FIG. 2 (8) and a pipe of FIG. 2 (9) are laid on the inside of the box for water drainage. To the base of the inner side of the inner flange summed up pipe 2 (10) for supplying air from the compressor. When air is supplied with the closed taps of Fig. 2 (15) and Fig. 2 (16), it will freely fill the inner space under the grate and after its injection will begin to penetrate through the layers of crushed stone, pebbles and soil, thereby providing aeration of plant roots and, if necessary drying the soil.

Under the bottom of the sealed box are tanks 2 (11), which serve to accumulate water after rainfall for further irrigation of plant roots. Excess water is discharged into the sewer through the pipe of Figure 2 (13). From the pipe of Fig. 2 (10) to the reservoirs, the pipe of Fig. 2 (12) is connected. Water is pumped into the lower part of the box after air is supplied to the tanks of FIG. 2 (11) through the pipe of FIG. 2 (12) with closed taps of FIG. 2 (14) and FIG. 2 (16). The air pumped by the compressor will squeeze out water from the tanks of FIG. 2 (11) through the pipe of FIG. 2 (9) to the bottom of the box to the lower soil level, due to the capillarity of which the desired humidity will be provided. The proposed utility model allows you to keep the grass lawn of the sports ground in optimal condition throughout the sports season in open-air stadiums and under the roof.

The claimed technical solution allows to achieve the following results:

- increase the speed of air supply to the root system,

- provide plant roots with water from tanks,

- provide, if necessary, the drying of the soil,

- improve the quality and longevity of lawn fields.
