Construction plan of artificial turf for standard soccer field

I. Construction Principles When building a new stadium, it is first necessary to consider its location and the direction of the playing field. Should generally be chosen where there is plenty of sunshine, fresh air, high groundwater and easy drainage. At the same time, the vertical axis of the venue should be chosen in a north-south direction so as to keep athletes, spectators and other people away from the strong sunlight; try to have enough around the stadium. Space for easy future development; there are roads and railroads close to the city to make it easy for visitors to come and go. In addition, consider the harmonious surroundings and reflect the principles of safety and comfort.
II. Construction Requirements The football field must be absolutely flat and natural and should be equipped with a complete drainage system.
1. Field Line: The shortest distance from the venue line to the screen: 6 meters from the sideline and 7.5 meters from the goal line. There should be a turf edge that is not less than 1.5 meters wide outside the edge of the playing field.
2. Sewer: The venue must have a drainage system to prevent heavy rain from affecting the race.
3. Emergency Aisle: First-aid passage with direct access to the ambulance and fire engines.
4. Billboards around the site: When constructing a new stadium, it must be noted that the placement of billboards around the site is unstoppable to the audience. The maximum height of a typical billboard is 90 cm. The minimum distance between the playing field line and the billboard is 5 meters outside the border, 2 meters behind the goal line, and 3.5 meters at the goal area.
5. Flagpoles: At least five flagpoles must be installed in the stadium or related facilities must be equipped with at least five flags.
Third, the soccer field specification football match venue is rectangular, its length must not be greater than 120 meters or less than 90 meters, the width cannot be greater than 90 meters or less than 45 meters. In any case, the length must exceed the width. FIFA's specifications for approved venues are 105*68 meters.
The length of the standard playing field is called the sideline, and the width of the standard playing field is called the end line. The entire playing field is surrounded by two lines and two end lines. The width (12 cm) of each line is included in the site (see Figure 1), and the surrounding buffer zone is not less than 2 meters.
Fourth, the ground requires slopes on both sides of the slope 4 degrees toward the periphery 4 slopes toward both ends 3‰

The ground of the competition venue should be a turtleback slope, and the slope of the lawn venue is 4‰-5‰, which is conducive to drainage. Create better conditions for athletes' competitions so that they do not suffer injury accidents when they make difficult collisions in the game and training.
The basis of artificial turf is recommended to use economical c25 cement concrete with a thickness of 180mm-200mm.
Fifth, the quality requirements of artificial turf on the cement foundation
1. Flatness: The pass rate is above 96%, and the 5 meter straightedge error is 3mm.
2. Slope: 8 turns, straight 5 turns, and the surface should be smooth and smooth to ensure drainage.
3, strength and stability: the surface is uniform and solid, no cracks, no broken edges, smooth seams, cut to about 6000mm * 6000mm as well. Cushion compaction, density greater than 96%, after the medium-sized roller compactor, no significant wheel marks. Loose loose soil, waves and other phenomena.
4. Water-repellent layer: The new thicker water-repellent film shall have a lap joint area of ​​more than 200mm and a margin of more than 150mm.
5, maintenance period: basic maintenance period is 3-4 weeks.
