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

A device for heating a sports turf containing a primary heat exchange system connected to Central heating city network and via a heat exchanger with offline secondary closed system of circulation of the heat carrier is water or a solution of water with glycole - in the form of sealed parallel set of heat pipes, and obliquely placed under heat pipes below the cultural layer of soil and lawn drainage pipes (RF patent No. 2118080, A 01 G 9/24, op year).

The disadvantage of this device is that it does not provide the following conditions for the maintenance of sports turf in optimum condition throughout the sport season:

1) slow natural drainage of the soil;

2) the inability of the impact on the groundwater level, which in spring and autumn are very close to the surface, and this system only allows you to heat the soil, and not to affect the process of drying;

3) in the conditions of negative temperatures, there is a freezing of the upper soil layer.

Closest to the technical essence of the present invention is a sports ground, including consistently placed on the soil base is, with a turn two of the slope from the Central longitudinal axis of the pad, drainage system, made in the form located in the sub-soil drainage system drains covered with a drainage layer consisting of longitudinal drainage drains located along the Central longitudinal axis of the pad, cross drainage drains parallel to each other, and ring main drains, having a slope equal to the slope of the Foundation soil, and each communicating at one end with longitudinal drainage Drenai, and the other end with the annular main Drenai, and topsoil (RF patent No. 2096551, E 01 13/00, epubl g).

The disadvantage of this solution is slow natural drainage of the soil, as well as failure to influence on the drying process of the soil.

Sports turf have their own characteristics. Grass football fields must be completely smooth, able to endure frequent haircuts, to be resistant to adverse weather conditions.

To the surface of a football field met all the necessary requirements, vegetative layer of the earth in the whole field must be homogeneous and of uniform thickness. The soil should absorb the water and allow air to have some water-holding capacity, is needed to supply plant roots water is.

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

The technical task of the invention is to improve conditions for the development of the grass lawn, ensuring rapid drainage of rain water from the surface of the lawn and subsequent drying and warming of the soil, and the removal of freezing the surface of the lawn in freezing temperatures.

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

This technical result is achieved by the fact that in the Playground that includes a base with two rays from the Central longitudinal axis, on which laid drainage layer and soil-vegetation layer according to the invention on the basis of which part of the box, located on the inside rim is a pipe with a grate for drainage of water and a pipe for supplying warm air, and at the base of the knob on the inner side of the box is made groove.

It is advisable box is made of concrete.

The inner side can be made of concrete.

It is advisable inner side to perform a height of not less than 35 see

Search for distinctive signs showed the absence of the such, that demonstrates compliance with the invention, the criterion of "inventive step".

On the attached figure 1 presents the scheme of sports fields, a top view, figure 2 - section a-A.

Playground consists of the base concrete box 1, the concrete of the inner rim 2, a layer of crushed stone 3, pebbles 4, the ground layer 5, the grooves 6, pipes for water drainage 7, grating 8, a pipe for supplying warm air 9.

The concrete base of the box 1 is made of two rays from the Central longitudinal axis. Concrete box 1 is sealed and prevents the penetration of rain and melt water inside the perimeter of the sports turf, and the output of the air outside the inner perimeter concrete box 1 (side 2), which is a very important factor. Concrete inner side 2 prevents the penetration of air pumped by the compressor, outside the zone, which gives the opportunity to operate this technology. In the zone And the soil need to ride more severe rink than in the zone of the Century On the basis of a concrete box 1 is laid a layer of crushed stone 3 and a layer of pebbles 4, which height is 100 mm, Then poured a layer of soil 5. Base of inner side 2 on the inner side of a concrete box 1 padded groove 6 and the pipe 7 grid 8 for water drainage. The grid 8 is designed to prevent gravel or Gal is key in the pipe 7. To the base of the inner side of the inner rim 2 summed up the pipe 9 for supplying warm air. When the supply of warm air compressor through a heat gun (not shown) air (white lines in figure 2), penetrating through the layer of soil that forms on the surface of the lawn air heat cushion, which prevents the freezing of the top layer of lawn in the winter. During the remainder of the year is to dry the soil and provide plant roots with air. During an air supply pipe for water drainage 7 overlaps. Inside line pipe 9 for supplying air is connected to a pipe from the vacuum pump (not shown in the figure). The vacuum pump provides quicker removal (black lines in figure 2) rainwater. During operation of the vacuum pump tube 7 for water drainage is blocked.

The present invention allows to maintain turf sports grounds in optimum condition throughout the sports season.
