A method of creating a cultural turf lawn and cultural
(57) Abstract:Prepared construction site, drainage system, surface or under the surface of the lawn stack system piping for drainage and/or heating of the sod lawn using system teploreguliruth. Depending on the functional purpose lawn and climatic conditions on the elements of the system teploreguliruth, ie electric cables and pipes, spread draining materials that cover the soil layers or plates ready turf. Electric cables and pipes can be laid in lawn turf and/or to a depth of 3 to 50 cm from the surface of the lawn and with a distance between them of 3 - 50 see the hottest period for cooling the sod lawn pipes pumped chilled working agent. In the cold season carry out heating of the lawn through the use of pipes with coolant and electric heating elements. Depending on climatic conditions, providing heating or cooling the sod can maintain the high performance properties of grass. 2 S. and 2 C.p. f-crystals, 2 Il. The invention relates to agriculture and stroitelstva purposes, and can be used in the construction of football fields, Rugby, American football, hockey, tennis courts and other sports facilities, as well as the creation of the soil conservation and other types of lawns.From the patent literature known sports ground, containing consistently placed on the base, a drainage layer with pipes, soil with sod and teploreguliruth. Culverts are made conductive, connected with a source of electric current, tokovodov and elektrosokirani from the distribution and header pipes. /see USSR Author's certificate N 1738886, E 01 C 13/00, 1992/.However, the known Playground because of the multi-layered and very complex structures is very costly and inefficient. In addition, these structures playgrounds are not able to provide a uniform and adjustable warming lawn turf, as well as to effectively vary the parameters of the warm-up lawn depending on the functional purpose of lawns, local building and climatic conditions. All this ultimately becomes the cause of the sharp decline in the quality characteristics teresti adjustable warm-up lawn turf in the horizontal and vertical directions, in the rapid growth and development of the grass lawn in the spring and maintaining the necessary quality characteristics of lawns in autumn-winter period, the possibility of providing in the hot dry season cooling topsoil and sod, maintain a high operational properties of the crop, and increase efficiency through simplicity and performance of the cultural construction of the lawn.The invention illustrated by the drawings, in which
Fig.1 shows a cross-section of cultural turf;
Fig.2 is a view of the lawn in the plan.The essence of the invention.A method of creating a cultural lawn includes laying on the prepared construction site drainage system, the base or the surface of the lawn system piping for drainage and/or heating of the sod lawn using system teploreguliruth. The proposed method of establishing cultural turf differs in that the system teploreguliruth with circulating pipes working agent in the hottest period is used for cooling the sod lawn by pumping through pipes chilled working agent. Depending on the functional purpose of the lawn, from local straw tubes spread draining materials, which cover soil layers or plates ready lawn turf, or laid in lawn turf to a depth of 3-50 cm from the surface of the lawn and the distance between 3-50 seeCultural lawn contains consistently placed on the base, a drainage layer with pipes, soil with sod and teploreguliruth, which differs in that it is equipped with a source of cooled working agent circulating through the pipes to cool the turf, and the system elements teploreguliruth and/or pipes are laid in lawn turf and/or to the depth of 3-50 cm from the surface of the lawn and the distance between 3-50 seeAs a system teploreguliruth applied thermal engineering devices or electric or electric heating cables, or electric, or heat-generating or heat-exchange installation.The drainage system of the lawn consists of drainage layers and/or drainage channels and pipes, filled and/or covered drainage materials.Compensation of heat loss of a sod lawn at ambient temperatures, equal to the average temperature of the coldest five-day week in the spring and autumn period in this area should obespechivali, as well as the dissipation of sod lawn constantly changing. Consequently, the quantity of supplied heat needs continuous adjustment.The problem is solved in that in the present invention system is teploreguliruth. The method includes laying on the prepared construction site drainage system or the Foundation soil under the turf cultural lawn or directly in lawn turf system teploreguliruth containing thermal devices or electric or electric heating cables, or electric, or teploreguliruth, or heat exchanger installation, ensure the use of thermal effect of electric energy for heating the sod lawn.Instead electrothermal installations or in conjunction with them can fit system heat exchanger piping for heating the sod pipes coolant, which is heated outside of the heated areas of the heat generating or heat exchange devices /not shown/ and then transported by pipeline to the place of heating lawn turf.Artificial heating, consisting of trove and sod cultural lawn by pumping them chilled coolant.Configuration, density, number and depth of laying thermal systems appliances, electric cables, electric heating elements or pipes with coolant, is placed under the sod lawn or directly in it, vary depending on the functional purpose of the lawn and other construction conditions.The greatest effect of the regulation of heat supply provides automation of the heating system, allowing to take into account heat, heat loss, as well as thermal inertia and accordingly to adjust the functioning of the whole system of artificial heating turf.The design of cultural turf includes the base 1, drain 2 drain tubes 3, filled or covered with drainage materials 4, electric cables 5, the heating elements or pipes with circulating through it cooled.Electric cables or pipes on top are covered drainage materials 6 /crushed stone, sand, gravel/, which are placed on the soil layers or sod lawn 7. The most effective is the system in which the coolant moves from the inlet pipe-manifold 8 through the pipes, proistemi artificial heating of the sod cultural lawn begins with thorough planning /profiling/ Foundation soil. For example, the construction of sports fields and sports grounds with lawn turf /football fields, tennis courts, etc./ first using the product aligns the soil at the base of the construction of sports fields and him to give the necessary slope to ensure drainage of water filtered through the soil layers from the surface of the lawn surface.In profiled the Foundation soil are cut drainage ditches or drainage pipes are laid and covered various drainage materials /rubble, pebbles, sand, etc./
This was followed by draining layers a drainage system stacked electrical cables or heating elements or pipes with circulating on him coolant. Usually the coolant, use different types of antifreeze. Pipes can be made of various materials, including synthetic, for example polyethylene.Depending on local climatic and other construction conditions of electric heating elements and pipes are laid at a depth of 3 cm to 50 cm from the surface of the lawn. The distance between the tubes may range from 3 cm to 50 cm, on average, to create F pipes.The heat transfer medium to heat the pipes and, consequently, soil and lawn turf, pre-heated to the operating temperature of the heat generating or heat exchange devices, and pumped through pipes by means of pumps /not shown/.New opportunities are opening using a system of pipes with coolant as for artificial heating of the soil cultural lawn in the cold season, and for cooling in hot arid period. While not required to install any additional cooling of the heat carrier. Simply disable teplogeneriruyuschie or heat exchange device. The temperature in this case will be low enough to provide the necessary cooling of the soil of the lawn.This combined use of artificial heating cultural lawn is very important in the construction of sports fields in regions with hot, dry, continental climate or extreme weather conditions. 1.

FIELD: agricultural production, in particular, plant growing.
SUBSTANCE: apparatus has device for measuring area of stem section and working tools. On the basis of measurements, voltage supplied to working tools is adjusted. Optimal conditions are created for plant treatment regardless of diameter of stems. Also, power consumption is reduced owing to employment of end switches adapted for automatic switching-off of power units of working tools in case of "idle stroke".
EFFECT: increased efficiency and reduced power consumption.
