Technical field

The technical solution concerns a system of underlay layers of a sports ground with an artificial surface.

BACKGROUND OF THE INVENTION

Sports grounds must meet certain basic requirements to be functional and usable for sports purposes. The basic requirements for the base layers are flatness of 5 mm per 4 m, strength and sufficient water drainage. In the sports pitches hitherto known, the required parameters were achieved such that the base layers of the pitches consisted of layers of aggregate with a thickness of 200 to 600 mm and a system of drainage pipes. The aggregate layer consists of stone layers of different fractions. These stone layers are arranged so that the bottom layer contains the aggregate with the largest fraction, and on this layer other stone layers are deposited, each of the higher layers containing the aggregate of a smaller fraction than the layer below it. Under the aggregate layers, drainage pipes are placed all over the playground filled with aggregates, which collect water from the playground and divert it to the drainage pipes located along the perimeter of the playground.

The disadvantage of this technical solution is that when making such playgrounds it is necessary to excavate grooves in the pitch to accommodate the drainage pipes. After the drainage pipes have been installed, they are covered with backfill material, but the backfill material cannot be sufficiently compacted due to possible damage to the drainage pipes, resulting in stones falling in the subsoil and irregularities in the ground surface when using the pitch.

The disadvantages of the technical solution are also the large amount of stone material necessary for the construction of the playground, the complexity of the technological process and the lengthy construction of the playground. This results in high costs for the construction of such playgrounds which are reflected in their price. Another disadvantage of this technical solution is its negative impact on the environment caused by the need to extract and import large quantities of stone material.

The main disadvantage of this technical solution is insufficient drainage of water from the pitch caused by insufficient drainage pipe drainage efficiency as well as clogging of holes in collecting drain pipes unless they are wrapped in geotextile.

The essence of the technical solution

The above-mentioned disadvantages are substantially eliminated by the underlay system of the sports ground with artificial surface according to the present invention, which consists in that it consists of a compacted layer of loose material on which the drainage geocomposite is deposited and on which the surface layer is deposited. The pitch of the pitch has a gradient of 0.1 to 10%. At least one side of the perimeter of the sports ground is a seductive gutter.

The layer of bulk compacted material may consist of stone and / or cinder and / or clay, which is compacted and may have a thickness of 10 to 400 mm. The surface of the sports field preferably has a gradient of 0.5 to 0.75%. This gradient can be achieved by dropping the layer of bulk compacted material, but also by dropping the other layers.

The surface layer is preferably an artificial turf. An elastic pad, preferably 15 mm thick, and / or a bulk material layer preferably between 1 mm and 300 mm thick, may also be disposed between the drainage geocomposite layer and the surface layer.

The surface of the sports field according to this technical solution is sloped. The slope can be turtle-back, roof, left-sided or right-sided. The location of the drainage channel depends on the type of slope of the sports ground. On the left-hand gradient the trough is located on the left long side of the sports field. On the right-hand slope the trough is placed on the right long side of the sports field. At the roof slope, the gutter is located on opposite facing sides of the sports ground. At the turtle slope, the trough is preferably located around the perimeter of the entire sports field.

The advantage of the proposed technical solution is that during the construction of a sports field according to this technical solution, the performance of excavation and backfill work is only necessary to the extent that the flatness and strength of the ground base is ensured. Another advantage is the smaller amount of compactable bulk material required, which results in lower overall costs and less effort to build a sports field. Since it is not necessary in the present technical solution to store all drainage pipes, it is possible to sufficiently compact the loose material without jeopardizing their damage and thus to avoid any surface irregularities resulting from the use of the Sports Field. Another advantage is sufficient water drainage, which is ensured due to the properties of the drainage geocomposite. The sports field according to this technical solution meets the basic requirements for sports fields.

BRIEF DESCRIPTION OF THE DRAWINGS

The technical solution is explained in more detail by means of the figures in the drawings. 1 is a cross-sectional view of a sports field according to the present invention with a right-hand gradient; FIG. 2 shows a cross-section of a sports field according to the present invention with a roof gradient.

Example of technical solution

Example 1

A sports field according to this technical solution with a right-hand slope, which is shown in FIG. First

The sports ground on the existing ground 7 consists of a layer of loose material 1 with a thickness of max. 200 mm, of a layer of drainage geocomposite 2, and a surface layer 3. The layer of bulk material 1 is formed of stones, is compacted and has a gradient of 0.75%. The surface layer consists of artificial turf. On the right long side of the perimeter of the sports ground there is a seductive trough 4.

Example 2

On the basis of an older sports ground, a sports ground according to this technical solution with a roof slope, which is shown in FIG. Second

The sports field consists of an existing layer of aggregate 6, a compacted layer of loose material 1 consisting of an existing slag layer, a drainage geocomposite layer 2, an elastic substrate 5 and a surface layer 3 formed of artificial turf. On the right and left long sides of the perimeter of the sports field there is an alluring channel 4. The existing layer of slag has been sloped and compacted to have a gradient of 0.5% and a maximum thickness of 150 mm. The other layers have a uniform thickness and follow the slope of the compacted bulk material layer 1.

Industrial usability

The practical application of the proposed solution is obvious and is useful for the construction of a sports field, including a sports field that meets international requirements for sports fields. The sports field according to this technical solution is intended for the performance of sports, especially football and other ball games.
