The invention relates to the construction and agriculture, in particular to the technology of construction of the drainage system of cultural turf intended for sports, arts, conservation and other purposes, and can be used in the construction of football fields for Rugby, American football, hockey, tennis courts and other sports facilities, as well as creating decorative, soil and other types of lawns.

From the patent literature known sports ground and the technology of its construction, including the creation of multilayer coating of the ground, synthetic films and the drain conductive layer (see jellema to create turf, designed to withstand significant loads when conducting sports competitions.

Closest to the claimed technology of construction of the drainage system of cultural turf is the technology of construction of sports field drainage system, including the serial manufacture of the base, drainage and soil layer, running the bases with gradients and drainage system made from drainage drains and drainage layers, conduct longitudinal drainage drains along the Central longitudinal axis of the lawn, and then ring main drains and cross drainage drains (see RF patent N2096551, E 01 C 13/00, 20.11.1997).

However, this technology does not provide optimal conditions for growing turf surface and drainage system quickly gets cluttered and out of order, and as a consequence lawns becomes unfit for use, which necessitates frequent repair.

The invention achieves the following technical results in order to improve conditions for the development of the grass of the lawn, to ensure quick drainage of rain and melt water from the surface of the lawn, optimum quality characteristic of the invention.

The method of construction of the drainage system of cultural turf includes the serial manufacture of the base, drainage and soil layer, running the bases with gradients. The drainage system is made from drainage drains and drainage layers, conduct longitudinal drainage drains along the Central longitudinal axis of the lawn, and then ring main drains and cross drainage drains. The inclination of the Foundation shall be along or across or along and across the Central longitudinal axis of the lawn and, if necessary, cover the base of the waterproofing materials. The drainage system is placed in the base or in the drainage and filter layers are in the form of drainage drains or drainage pipe with a slope of 0.1-3.0% and fill or cover the drainage and filter materials.

As drainage and filter materials, filling or covering the drainage drains or drainage pipes, use crushed stone, gravel, slag, sand, organic materials or artificial origin.

Drainage drains and drainage pipes placed on the ground or in the draining materials, or for drainage or filter or gidroizolyator> Use drainage pipes with holes or without them.

The construction of the drainage system of the lawn begins with a thorough plan (profiling) of the Foundation using the product. The layout of the Foundation is to give its surface a uniform slope required for drainage water filtered through the soil-vegetation layer drainage layer. Gradients base, as a rule, 0.1 to 3.0% in excess of the upper elevations above the zero level, an amount equal to 0.01 to 0.3 M. the excess in 0,17-0,25 m to be the best, as numerous experiments with reduction or increase of this magnitude would lead to negative consequences. When the reduction in the slope above 0.1% rain and melt water went very slowly, decreased the effectiveness of the drainage, which led to over-watering of the lawn. In addition, the increase in slope above 0.3% significantly impede the movement of athletes on the surface of the sports turf and led to their fatigue.

After profiling the Foundation begin the construction of the drainage system, which begins with the device of longitudinal and transverse drainage drains or drainage pipes.

In Nicolosi lawn and align it with leveling or other devices. The depth of longitudinal drains 10-30 cm, width is also equal to 10-30 see Longitudinal length not given any bias. Its depth at all points in its passage along the longitudinal axis of the box exactly the same.

After the device longitudinal drainage drains pull a transverse drainage drains or laid across the lawn drainage pipes, tykwa them from the longitudinal axis of the lawn with longitudinal drainage Drenai. In places docking depth transverse drainage drains should be equal to the depth of the longitudinal drainage drains. Transverse drainage drains pull with a uniform slope, starting from the longitudinal drainage drains to the annular drainage ditch. The same slope give and transverse drainage pipes. The distance between cross drains or drainage pipes may be from 0.5 m to 15 m and they can get and give as transversely to the longitudinal axis of the lawn, and in accordance with any of the other configurations, for example, from the center of the lawn diagonally to its periphery.

FIELD: manufacture of plant covers used for beautification of streets, squares, construction of sportive grounds, as well as for landscape designing.

SUBSTANCE: method involves spraying organic adhesive onto fine-mesh basalt net by means of specially designed equipment for filling meshes to thereby create strong carrier base. Net is perfectly ecologically safe and allows seeds to be uniformly sown over the entire area of lawn. Adhesive used for providing lawn is functioning as nutritive compound for seeds and is used simultaneously for protecting seeds from external influence of moisture and air during prolonged periods. After drying in first drying chamber, mixture of lawn grass seeds is sown onto carrier base through dosing hopper, followed by applying onto given mixture of organic adhesive and drying in second drying chamber. After discharge from drying chamber, ready dry lawn is cut into parts of various lengths, wound into roll and hermetically packed in polyethylene film for further storage and transportation. Lawn is placed on site by unwinding roll onto preliminarily prepared ground and spilling nutrient mixture thereon, followed by heavy irrigation to provide for sprouts emergence. Nutrient mixture and lawn grass seed mixture compositions are worked out depending on climatic zone and composition of parent ground on which lawn is to be provided.

EFFECT: increased efficiency by providing uniform sowing of seeds over the entire lawn area, and damage-free transportation and handling of grown lawn.
