The core standards and adaptation logic of an eight-a-side football field on campus

The eight-a-side football field on campus needs to balance "teaching demands" and "field efficiency". Its standard size is 60m×40m (with a total area of 2,400 square meters, of which the lawn area is approximately 2,200 square meters), and it must strictly comply with the environmental protection and safety requirements of the "Synthetic Materials Surface Sports Fields for Primary and Secondary Schools" (GB36246-2025). The focus is on meeting the needs of daily physical education classes, extracurricular activities and small-scale on-campus competitions, without blindly pursuing professional competition-level configurations.

Three principles of core adaptation

• Safety first: Materials must pass TVOC and heavy metal tests, and the lawn's shock absorption rate should reach 45% to 70% to reduce the risk of sports injuries for students.

• Durable and wear-resistant: Suitable for high-frequency use of 4 to 6 hours a day, the lawn's wear resistance should reach over 30,000 times of friction without obvious peeling.

• Cost control: Adhering to the principle of "moderate initial cost + low maintenance cost in the later stage", artificial turf is given priority.

High Cost-Performance Cost Details (2,200 ㎡ Lawn Area + 200㎡ Ancillary Area)

1. Foundation engineering: The core cornerstone of durability

The foundation is the key to determining the lifespan of the site. Costs should not be overly compressed. It is recommended to combine "graded crushed stone + cement stabilizing layer", which takes into account both economy and stability

• Cement-stabilized layer: 15cm thick C20 cement-stabilized crushed stone (including curing), providing a flat base layer, 12-15 yuan per square meter

• Drainage system: U-shaped concrete drainage ditches (300mm wide × 400mm deep) are set up along the edge of the site, with sedimentation Wells at intervals of 15 meters and a slope of 0.5%. Natural drainage is used instead of mechanical systems to save costs, at a rate of 8-10 yuan per square meter

2. Lawn System: A balance between Safety and cost-effectiveness (Total budget: 121,000-154,000 yuan)

PE monofilament artificial turf is preferred for campus scenarios. The core parameters and costs are as follows:

• The main material of the lawn is 30-50mm high PE monofilament grass, with a density of 10,500 clusters per square meter and a weight of 8,800 dtex, which meets environmental protection standards

• Filling material: Quartz sand (20kg/㎡, particle size 0.3-0.5mm) + domestic SBR rubber particles (4kg/㎡, environmentally friendly and odorless)

• Bonding material: Environmentally friendly glue

3. Ancillary facilities: Just meet the basic functions

Based on the principle of "practical and sufficient", simplify unnecessary configurations:

• Fence system: 4m high-speed iron wire dipped plastic fence (hole diameter 50×50mm), which combines safety and vision, is more durable than soft nylon net, 40-50 yuan per square meter (perimeter 200m, area 800 square meters)

• Goal equipment: 2 sets of standard eight-a-side goals (made of steel pipes, with nets). Save costs by comparing prices online

• Field marking: Solvent-free acrylic marking paint is used to draw the edge lines, penalty areas, etc. according to the standards, simplifying the pattern design and reducing material waste

• Lighting system (optional) : If used at night, it is equipped with 4 8m high LED floodlights (illuminance ≥200lux)
