Commonly used in the construction of a football field artificial turf foundation has three categories: asphalt base, cement foundation, gravel base, using which type is mainly determined by the local climate and environment and budget, time, asphalt base especially for large temperature difference between the north and low winter temperatures The climate and environment, but also because of its high cost, for the warm and humid environment is not the most appropriate basis for the type of gravel base because of its simple construction, low cost, rapid drainage, more common in the South, but because of its steel and stability is poor, prone to loosen after prolonged use basis, resulting in uneven basis; therefore, in most regions of the country, cement concrete foundation became economical and practical, very high cost of artificial grass base type.
1, on the basis of surface roughness higher, in order to ensure consistency of the artificial turf surface layer thickness, elasticity uniform. Flatness pass rate of more than 95%, 5 m ruler error 3MM, slope: horizontal 8 ‰, vertical 5 ‰, semi-circular area 5 ‰, the surface should be flat, smooth, ensure drainage.
2, the base should have a certain strength and stability.
3, the surface uniformly solid, no cracks, no bad side Pock seams straight and smooth, with around 6000mm × 6000mm cut as well.
4, cushion compaction, the density of greater than 95%, after the medium-sized rolling machine pressure, no significant wheel tracks, no surface dust loose, wave and so on.
5, there must be impermeable layer of cement foundation, new PVC thick impermeable layer impermeable film, junction should be greater than 300mm, edge margin greater than 150mm.
6, consider leaving joints, width of 5 mm.
7, basic maintenance period of 2-3 weeks.
After basic lawn maintenance can pavement.
