How to build a artificial garden turf?
If the concrete covering layer. After the concrete is cured to cutting out of the expansion joints, to prevent thermal expansion deformation and crack. 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 garden 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.
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.
Artificial garden 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.
