Artificial grass has the advantages of bright appearance, green all the year round, vivid, good drainage performance, long service life, low maintenance costs, etc.
The quality requirements of artificial turf movement system are mainly concentrated in three aspects: hardness, flatness and drainage slope.
There are three common types of artificial grass foundation: asphalt foundation, cement foundation and gravel foundation. The type of artificial grass foundation is mainly determined by local climate environment, budget and time. Asphalt foundation is especially suitable for the climate environment with large temperature difference in the north and low temperature in winter. Gravel foundation is not the most suitable foundation type, because of its simple construction, low cost, rapid drainage, more common in the south, but because of its poor stiffness and stability, long-term use of foundation is prone to loosening, resulting in foundation irregularity; therefore, in most parts of the country, cement-concrete foundation has become. The basic type of artificial grass is economical, practical and cost-effective. Based on the rich experience of man-made grass system, Shuanghe Sports makes the following brief introduction to man-made grass cement concrete foundation:
1. Higher surface roughness is required to ensure that the surface thickness of artificial grass is uniform and uniform. The pass rate of flatness is over 95%.
The error of 5m ruler is 3MM, and the slope is 8, 5, and 5. The surface should be flat, smooth and guaranteed to drain.
2, the foundation should have a certain degree of strength and stability.
3. The surface is uniform and solid, no cracks, no rotten hemp surface, and the joints are smooth and straight. It is better to cut about 6000mm *6000mm.
4. The cushion is compacted, the compactness is more than 95%. After the medium-sized roller is compacted, there is no obvious wheel track, no loose floating soil, wave and other phenomena.
5. The cement foundation must have a water-proof layer. The water-proof layer should be thickened with new PVC water-proof film. The junction should be more than 300 mm and the margin allowance should be more than 150 mm.
6, we need to consider expansion joints, width of 5 mm.
7, the basic maintenance period is 2-3 weeks.
