Abstract

FIELD: sportive constructions, in particular, constructions which may be partly used in agriculture.

SUBSTANCE: sportive ground has base with two slopes extending from central longitudinal axis, drainage layer and soil plant layer placed onto base. Base is part of box-like construction. Rim is placed on inner side of base. Pipe with water discharge grid and warm air supply pipe are mounted on base. Groove is provided at base inner side.

EFFECT: provision for circulation of air in ground, improved conditions for development of lawn herbage, quick discharge of rain water from lawn ground surface, followed by drying and heating through of ground, preventing of ground surface from freezing-through under winter conditions.

Description

The invention relates to sports facilities, partially can be used in agriculture.

A device for heating a sports lawn is known, comprising a primary heat exchange system connected to the central heating of the city network and by means of a heat exchanger with an autonomous secondary closed systemic circulation of the heat carrier — water or a solution of water with glucose — in the form of sealed heat pipes installed in parallel and inclined under heat pipes below the cultural layer of soil and lawn drainage pipes (RF patent No. 2118080, A 01 G 9/24, op.27.08.98).

The disadvantage of this device is that it does not provide a number of the following conditions for maintaining the sports lawn in optimal condition throughout the sports season:

1) slow natural soil drainage;

2) the impossibility of influencing the level of groundwater, which in the spring-autumn period is very close to the surface, and this system only allows heating the soil layer, and not affect the process of drying it;

3) under freezing conditions, freezing of the upper soil layer occurs.

Closest to the technical nature of the present invention is a sports ground, including sequentially located base soil made with a slope of two slopes from the central longitudinal axis of the site, a drainage system made in the form of a system of drainage drains located in the base soil, covered with a drainage layer and consisting of longitudinal drainage drain located on the central longitudinal axis of the site, transverse drainage drains parallel to each other, and an annular main th drain, having a slope equal to the slope of the soil of the base, and each communicating at one end with a longitudinal drainage drain, and at the other end with an annular main drain, and a soil and plant layer (RF patent No. 2096551, Е 01 С 13/00, publ. November 20, 1997).

The disadvantage of this solution is the slow natural drainage of the soil, as well as the impossibility of influencing the process of drying the soil.

Sports lawns have their own characteristics. The grass cover of the football field must be completely even, able to tolerate frequent haircuts, and be resistant to adverse weather conditions.

In order for the surface of the football field to meet all the necessary requirements, the vegetation layer of the earth throughout the field must be uniform and of equal thickness. The soil should absorb water well and allow air to pass through, have some water-holding ability, necessary for supplying plant roots with moisture.

The principle of operation of the present invention is that if water under the influence of its own gravity and capillary structure of the soil penetrates into its lower layers, then the air pumped by the compressor goes up.

The technical task of the invention is to improve the conditions for the development of grass lawn, providing rapid drainage of rainwater from the surface of the lawn and subsequent drying and heating of the soil, as well as the exclusion of freezing of the surface of the lawn at low temperatures.

The technical result is the creation of air circulation in the soil.

This technical result is achieved by the fact that in the sports field, including a base with two slopes from the central longitudinal axis, on which the drainage layer and the soil plant layer are laid, according to the invention, on the base, which is part of the box, a side is located on the inside, a pipe with a grill is located a pipe for supplying warm air is installed to drain the water, and a groove is made at the bottom of the side of the box.

It is advisable to box made of concrete.

The inner rim can be made of concrete.

It is advisable to perform an inner rim with a height of at least 35 cm.

Search by distinguishing features showed the absence of such, which indicates the compliance of the invention with the criterion of "inventive step".

The attached figure 1 presents a diagram of a sports field, a top view, figure 2 is a section aa.

The sports ground consists of the base of a concrete box 1, concrete inner rim 2, a layer of crushed stone 3, a pebble layer 4, a soil layer 5, a groove 6, a pipe for water drainage 7, a grill 8, a pipe for supplying warm air 9.

The base of the concrete box 1 is made with two slopes from the central longitudinal axis. Concrete box 1 is airtight and prevents the penetration of rain and melt water into the perimeter of the sports lawn, as well as the air outside the inner perimeter of concrete box 1 (side 2), which is a very important factor. Concrete inner rim 2 prevents the penetration of air pumped by the compressor beyond the zone B, which makes it possible to operate this technology. In zone A, the soil must be rolled with a heavier roller than in zone B. A layer of crushed stone 3 and a layer of pebble 4 are laid on the base of the concrete box 1, which are 100 mm in height. Then a layer of soil is poured 5. At the base of the inner rim 2, a groove 6 and a pipe 7 with a grill 8 for water drainage are laid on the inside of the concrete box 1. The grill 8 is designed to prevent crushed stone or pebbles from entering the pipe 7. A pipe 9 for supplying warm air is brought to the base of the inner side of the inner rim 2. When warm air is supplied by the compressor through a heat gun (not shown in the figure), air (white lines in Fig. 2), penetrating through the soil layer, forms an air heat cushion on the surface of the lawn that prevents the freezing of the top layer of the lawn in winter. In other seasons, it serves to dry the soil and provide the roots of plants with air. During air supply, the pipe for draining water 7 is closed. Inside the highway, the pipe 9 for supplying air is connected to the pipe from a vacuum pump (not shown in the figure). The vacuum pump provides faster drainage (black lines in figure 2) of rainwater. During operation of the vacuum pump, the pipe 7 for draining water is blocked.

The present invention allows to keep the grass cover of the sports ground in optimal condition throughout the entire sports season.
