Basic site requirements

◎Foundation: Cage football artificial turf foundation, cement concrete foundation, asphalt foundation, which are widely used in the industry. This paper introduces the construction acceptance criteria of the above two common artificial turf football field foundations in detail: flatness, slope (drainage design), foundation strength and stability.

1. Cement concrete foundation construction standard: cement concrete foundation construction (the cement concrete site foundation must have three parameters of flatness, slope, strength and stability)

★ Site Sizing: Use the measuring tool to accurately measure site sizes and mark each site size with a different bright color.

★ Flatness: The flatness error of the construction site is controlled within the allowable range, and the error of 5 meters is guaranteed to be 3mm.

★Drainage: Cage football field foundation adopts turtle-back drainage design. The slope of the foundation of the site should be controlled within 3‰-5‰. Specific slope requirements, the slope of the central site is controlled at 3‰-4‰, the curve is controlled at 8‰, the straight road is controlled at 5‰, and the semicircle area is controlled at 5‰  (site maintenance). The surface is flat and smooth, which is convenient for site drainage).

★ Compression stability: Use a medium-sized roller compactor to compact the foundation, the cushion foundation should be compacted, and the compaction density should be controlled at more than 95%; the roller compactor should ensure that there are no obvious wheel marks, loose soil, waves, etc. , in order to ensure that the foundation site has a certain compressive resistance and stability.

★Water-blocking layer: The cement concrete base should have a water-blocking layer, and the water-blocking material is a new type of PVC thickened water-blocking film.

★Curing period: The curing period of cement concrete foundation is 21 days.

2. Asphalt foundation construction standards: Asphalt foundation construction is the same as cement concrete foundation, and has three parameters: flatness, slope, strength and stability.

★Flatness: The qualified rate of asphalt foundation flatness is more than 95%, and the flatness error is controlled within 3 meters and 3 mm.

★Drainage: The slope is controlled within 1‰-4‰, and the specific slope indicators are as follows: horizontal <1‰, vertical <1‰, high jump area <4‰, the slope is kept flat and smooth to ensure normal drainage ( The drainage system must drain from the inside for half an hour after heavy rain).
