Abstract

Use: construction of outdoor sports grounds. SUMMARY OF THE INVENTION: A sports ground comprises a ground base, a waterproofing film, a drainage electrically conductive layer of metallurgical slag with culvert pipes located therein and holes filled with granular material, the height of a capillary rise of water in which exceeds the height of the drainage layer. At the same time, the culvert pipes are connected at one end of the site to the distribution pipe, and at the other end to the collector pipe, the collector pipe and / or the distribution pipe containing a branch with a locking device and a drain pipe, the discharge edge of which is located between the marks of the sole of the floor and its outer surface. . In addition, the water outlets are electrically conductive. A ground covering is located above the base of the site. 1 hp ff, 2 ill. 1A

Description

The invention relates to the construction of open sports grounds, such as football fields, grass courts, which provide for the construction of ice cover for the winter period.

The purpose of the invention is to improve the operational properties of the site by improving the quality of humidity control.

FIG. 1 shows a sports field, a plan view; in fig. 2 shows section A-A in FIG. one.

The playground consists of a soil base 1, a drainage layer 2 and a coating 3, the drainage layer made of metallurgical slag, contains perforated metal culverts 4, inclusions in the form of fine sand 5, placed in holes 6, and (or) in the form of fibrous material 7 and is located on the waterproofing film 8.

The conduit pipes are parallel to each other, the current leads are distributed in the phases of the source of electrical current (the current leads and the source of electrical current are not shown) and are electrically insulated at one end of the site to the distribution pipe 9 and at the other end of the site to the collector pipe 10.

Fine sand has a capillary height of tens of centimeters exceeding the depth of

with

holes, while the fine-grained sand is directly adjacent to the coating, and the sand itself can be obtained, like the drainage layer, from metallurgical slag and can be electrically conductive. For the formation of inclusions from fibrous material, industry waste of predominantly mineral origin (asbestos) in the form of individual fibers or scraps of material are used.

The collector pipe has a branch 11 with a drain pipe 12 and a locking device 13, and the drain edge of the pipe 12 (not shown) is enclosed between the foot marks and the outer surface of the coating. The distribution pipe through the shut-off device 14 is hydraulically connected to the water supply system 15.

The drainage layer and pipes 4, 10, and 11 (shut-off device open) form a drainage system that drains water from under the cover into the sewage 16. The pipes 9 and 4 and the drainage layer with inclusions (shut-off device closed) form a feeding system that provides water to the grass cover 17. The source of electric current with tokovods, pipes 4 and the drainage layer form a heating system, which during the spring period releases the drainage system from ice, heats the cover and thaws the ice cover or snow.

When the water level 18 in the drainage layer is lower than the bottom of the coating, the locking device is closed, and the water stored in the drainage layer in the spring, through the capillaries of fine-grained sand and fibrous inclusions from the drainage layer, rises to the root system of the grass cover.

During the dry summer period, the groundwater supply in the drainage layer is replenished from the water supply system, while the overflow pipe limits the amount of hydrostatic pressure of water on the coating.

During the winter period by opening the locking device, the drainage layer is dehydrated, as a result of the porosity of the slag, the drainage layer protects the base from freezing, which prevents the base in the case of bonded soils from deformations by swelling and thus reducing the quality of the ice field.

The use of the invention allows to improve the quality of construction sites, simplify their operation and increase the duration of their use throughout the year.
