First, the advantages of green artificial football grass field:
1. Good elasticity, and the surface has shock absorption effect.
2. It is completely free to walk on the top, providing the same torque detachment rate as dense grass turf. It will not sprain ankle or knee ligament.
3. Ball speed and rebound force are almost the same as natural grass.
4, excellent traction, so that athletes can accurately determine the direction of the ball
5, anti-ultraviolet, good wear resistance, reduce noise.
6, the surface will not form mud, will not freeze, there is no need to reschedule due to weather. Can provide the best performance in any weather.
7. The anti-sliding resistance of the safety surface is extremely low, providing a soft support feeling, and the internal filling prevents micro-organisms from growing.
8, long life, multi-purpose, can be used continuously, without the need to close the sports field for grass growth.
9. There is no need to sow, re-turf, construction, manual care, and machine management, which saves maintenance costs and losses of natural grass fields.
10, good drainage, paved on gravel foundation can absorb 26mm of rainwater per hour
The bald top is natural grass, and the bottom is an artificial grass field.
2. Acceptance criteria:
Acceptance criteria for natural turf football fields:
1. Appearance: The lawn is flat, the grass seedlings are dense and uniform, and the grass seedlings grow vigorously and continuously, and there are no dead seedlings and no loess.
2. Thickness: The grass seedlings should be maintained at the most suitable height of 3-4 cm to ensure the longest life of the turf surface. If a football field is involved in a throwing event, the grass must be cut to a height of 1.5-2 cm.
3. Slope: The ground of the football stadium should be a turtle-shaped slope with a slope of 4 / 1000-6 / 1000.
4, flatness: local ground should not be uneven. Not more than 10 mm within a measuring distance of 3 meters, and not more than 8 mm within a measuring distance of 0.5 meters.
5. Drainage: 20 minutes after the rain stops, there should be no standing water on the ground.
6. Water supply: spray evenly without blind spots.
Acceptance criteria for artificial grass football fields:
1. Visual appearance: The surface is flat, the color is uniform, and there is no obvious unevenness.
2. The width and positioning of each function line and point line are accurate, and the size of the function area meets the standard.
3. There is no obvious gap between the two turf seams, and the adhesion is compact without adhesive. The gap does not exceed 5mm.
4. The surface of the filled sand and rubber particles is clean and full, and there is no obvious height difference.
5. Slope: The slope of the artificial sports lawn site is 4 ‰ -6 ‰, and it must have good drainage performance.
6. Whether there is any odor.
