How to build a artificial soccer turf?
Artificial soccer turf based on surface roughness of high degree, in order to ensure the consistency of the artificial grass surface layer thickness of the, homogeneous elastic. Flatness qualification rate in more than 95%, 5 m ruler error 3mm, slope: transverse 8 per thousand, length of 5 per thousand, semi-circular area 5 per thousand, the surface should be flat, smooth, ensure drainage. Should have a certain strength and stability. Uniformly on the surface of a solid, no cracks, no broken edge pits, smooth straight seams, with about 6000 mm * 6000mm cuts as well.
Artificial soccer grass cushion compaction, the compacting degree was more than 95%. In medium rolling machine after the pressure, no significant wheel track, no loose topsoil, wave phenomenon. Cement foundation required water resisting strata and aquifuge the new PVC thickened water resisting film, junction should be greater than 300mm, edge margin greater than 150mm. Need to consider the expansion joint, width at 5 mm. Basic maintenance period for 2-3 weeks.
Artificial soccer turf by 3 layers of material composition. Base layer is formed of compacted soil, gravel layer and the asphalt or concrete layer. The base layer required a solid, no deformation, surface smooth and impervious, namely the general concrete ground. Because the hockey area is large, the construction must deal with the base layer, prevent sinking. If the concrete covering layer. After the concrete is cured to cutting out of the expansion joints, to prevent thermal expansion deformation and crack.
Above the base layer is a layer of buffer layer, usually composed of rubber or plastics, rubber elasticity is moderate, thickness.... foam with low cost, but poor elasticity, thickness 5 ~ 10mm thick lawn is too soft, and easy to sag; thin lack flexibility to buffer. The buffer layer to securely paste on the base layer, usually with white latex or all-purpose adhesive paste.
The third layer is the surface, for the turf layer. According to the surface shape of manufacturing a downy turf, annular curl shaped nylon silk turf, turf of foliate polypropylene fiber, nylon yarn preparation of permeable turf,. This layer must also by latex adhesive on the rubber or plastics. Construction must be fully gelatinize, followed by pressing firmly attached, not wrinkle folding.
