Artificial turf sports system on the basis of the quality requirements are mainly concentrated in three areas: hardness, flatness and drainage slope.
There are three types of artificial grasses: asphalt foundation, cement foundation, gravel foundation, which type is mainly used by the local climate environment and budget decision time, especially for the northern temperature difference and the winter low temperature climate environment, but also Because of its high cost, for the warm and humid environment is not the most suitable basis type, gravel foundation because of its simple construction, low cost, rapid drainage, more common in the south, but because of its poor steel and stability, long time Easy to use after the foundation loose, resulting in the foundation is not flat; therefore, in most parts of the country, cement concrete base has become economical and practical, cost-effective very high artificial grass base type.
Mitac Machinery According to the rich experience of artificial grass system, the artificial grass cement concrete foundation to do the following brief:
1, the basic surface roughness requirements are higher, to ensure that the artificial grass layer thickness consistent, uniform elasticity. Flatness pass rate of 95% or more, 5 m ruler error 3MM, slope: horizontal 8 ‰, vertical 5 ‰, semi-circular area 5 ‰, the surface should be flat, smooth, to ensure drainage.
2, the foundation should have a certain strength and stability.
3, the surface is uniform and solid, no cracks, no rotten side Ma face, seam straight and smooth, to 6000mm × 6000mm cut just as well.
4, cushion compaction, density greater than 95%, after the medium-sized rolling press pressure, no significant track, no loose soil, waves and so on.
5, the cement base must have a layer of water, the use of new PVC thickened water barrier film, the junction should be greater than 300mm, edge margin greater than 150mm.
6, need to consider to extend the expansion joints, the width of 5 mm.
7, the basic maintenance period of 2-3 weeks.
