Abstract

The invention relates to the construction of sports facilities, football fields, rugby fields and tennis courts used for sporting events on natural grass. The sports field comprises a base with slopes running from the central longitudinal axis, and a layer of soil and vegetation disposed on the base; furthermore, the following are arranged on the inner side of the base: a skirting, a water drainage pipe covered with a grille, and a pipe for supplying hot air. A groove is made at the base of the skirting on the inner side of a box. Supports and grilles are placed on the box bottom, on top of which are placed: a broken stone layer with a height of 50 to 100 mm, a pebble layer with a height of 50 to 100 mm and a soil layer. Reservoirs are arranged under the box bottom for collecting rain water for irrigating the root system, said reservoirs being connected to the groove via a system of pipes.

Description

PLAYGROUND

Technical field

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.

Prior level

Known sports field SU 1717690 from 04/20/89, IPC E 01C 13/00, including soil-cover, water-retaining and subsoil layers, a crushed stone layer, 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. Air inlet pipes with plugged ends are located at the ends of the perforated pipes, and vertical outlet pipes are connected to the air inlets and have an outlet at the level of the surface of the soil layer of the site. When using this device, it is more difficult to maintain a sports lawn even, able to tolerate frequent haircuts, and be resistant to adverse conditions throughout the sports season. A layer of crushed stone and pebbles makes it difficult for air to pass through this layer for normal grass growth.

Known sports ground RU 2263736 from 02/10/2004, IPC E 01 C 13/02 (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.

This technical solution is unstable when the groundwater level fluctuates and is not enough to solve the issue of soil drying.

Disclosure of invention

The objective of the proposed technical solution is the construction of such a platform that would meet all the necessary requirements: uniformity and the same thickness of the soil layer, should provide good absorption of water, outflow of water. The soil should pass air well, providing drying of the soil.

The problem is solved due to the fact that in the sports field, including the base with slopes from the central longitudinal axis, on which the soil plant layer is laid, moreover, on the inside of the base there is a side and a pipe, closed by a grate for draining water and a pipe for supplying warm air, and at the bottom of the side of the box there is a groove made on the bottom of the box, supports and lattices are laid on the bottom of the box, and a crushed stone layer from 50 to 100 mm high, a pebble layer from 50 to 100 mm high and a soil layer are placed on top of the box, and under the box bottom ovlivayut tanks for the accumulation of rain water and to further irrigation of the root system associated piping system with a groove. The proposed sports ground includes an airtight box with an inner rim), on which there are supports, lattices, a layer of crushed stone, pebbles (or similar materials), a soil-sand mixture rolled with rollers, providing aeration of plant roots and drying of the soil layer after air supply through pipe system, and under the bottom of the box are tanks for irrigation water of the root system (if necessary).

The best embodiments of the invention

A box made, for example, of concrete, has an outer perimeter of the rectangle, has walls of the box 1, an inner rim 2. The walls of the box 1 and the bottom of the box prevent rain and melt water from entering the perimeter of the sports lawn, which is a very important factor. The inner rim 2 prevents the penetration of air pumped by the compressor 17 under pressure outside the zone B, see Figure 2, directing it strictly upward (Figure 2 is indicated by arrows in zone B).

The bottom of the box is made sloping (in Fig.2 a slope from right to left).

At the bottom of the box are placed supports 3, FIG. 2, under the grilles 4, FIG. 2. On the stacked gratings 4, Fig.Z, a layer of crushed stone 5, Phir. 2, from 50 do10 mm and a layer of pebble 6, Fig.2, a height of 50 do 10 mm. Then a layer of soil 7 is poured, Figure 2. At the base of the inner flange 2, FIG. 2, a groove 8, FIG. 2, and a water pipe 9, FIG. 2 are laid on the inside of the box to drain water. An air pipe 10, Фиr.2, is connected to the base of the inner side of the inner rim 2, for supplying air from the compressor 17. When supplying air with the valves for the tank 15 closed, FIG. 2, and a valve for discharge into the sewer 16, Фи.2, it will freely fill the internal space under the grate 4 and after its injection will begin to penetrate through the crushed stone layer 5, the pebble layer 6, and the soil layer 7 outward, thereby ensuring aeration of the plant roots and, if necessary, drying of the soil. A water pipe 9, an air pipe 10, a backup pipe 12, a pipe for discharge into the sewer, form a pipe system that ensures the operation of the device.

Under the bottom of the sealed box are tanks 11, Figure 2, which serve to accumulate water after rainstorms for further irrigation of plant roots. Excess water is discharged into the sewer through a discharge pipe into the sewer 13, FIG. 2. From the pipe for air 10, FIG. 2, the pipe for the tank 12, FIG. 2 is connected to the reservoirs. Water is pumped into the lower part of the box after air is supplied to the tanks 11, FIG. 2, through the pipe for the tank, FIG. 2, with the closed air valve 14, FIG. 2, and the tap for discharge into the sewer 16, FIG. 2. The air pumped by the compressor 17 squeezes the water out of the tanks 11 through the water pipe 9 to the bottom of the box to the lower soil level, due to the capillarity of which the required humidity will be provided. The proposed technical solution 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,

- to provide plant roots with water from reservoirs 11, - to ensure soil drying if necessary, - to improve the quality and longevity of lawn fields. Industrial applicability

The proposed sports ground can be easily mounted on fields intended for sporting events, or in areas where stable grass cover is required all year round.

Thus, the technical solution meets the criterion of industrial applicability.
