What are the foundations of an artificial lawn soccer field?
The asphalt concrete foundation for tennis, field hockey, football, hockey field, which must use hydrophobic asphalt base, the other can use ordinary asphalt base; football field four basic are applicable, can choose according to the actual situation, recommend the use of cement powder, the basic rule of the three hydrophobic gravel foundation; the court can use cement based.
All materials used in a and foundation construction shall be used for construction before the inspection is qualified;B, based on a uniform solid appearance: the surface without obvious road marks, smooth and no crack, no broken edge pushing, loose, wave, rough surface, smooth seams, no water blocking;C, when the water test, drainage after 120 minutes after the rain, allowing the presence of water, but the thickness of water may not be greater than 4mm;D, after the completion of 10 * 10 square meters net retest elevation, and calculate the slope of drainage, drainage slope is less than 0.5%, and the error is <1.5%;The compaction density of E and stable layer shall not be less than 93%;The pass rate of F, flatness, slope and site elevation should be above 85%;G, thickness deviation + 10%.
1 asphalt concrete foundation:A. (ordinary asphalt asphalt base often choose, slightly cheaper);B. hydrophobic asphalt (the cost is too high, construction is complex, with less); strength and good ductility, is the ideal foundation, especially suitable for cold weather in the north and the temperature difference of a large area, but the cost is expensive.2, cement foundation: good strength, economical and practical, suitable for small temperature difference areas, but poor ductility;3, cement stone powder foundation: short construction period, low cost, good drainage performance, but poor weather resistance, easy oxidation, resulting in irregularities;4, gravel hydrophobic Foundation: the lowest cost, good drainage performance, but no flatness, more problems.
