Composite artificial turf structure with shock absorption and drainage

摘要

An artificial turf is disclosed which comprises an outer artificial grass layer having a generally uniform exterior playing surface. A deflection layer is disposed below the artificial grass layer. The deflection layer has a prescribed height to provide resiliency for absorbing impact shocks from foot traffic and playing on the artificial grass layer. The deflection layer has a plurality of interstices providing open passages for water drainage; and loose particles are dispersed into the interstices of the deflection layer up to a prescribed level to provide stability and enhance shock absorption so that the deflection layer deflects when the artificial grass is impacted to assist in absorbing the impact and maintain normal playing action of the playing surface of the artificial grass layer. A base surface is disposed below aid deflection layer which includes a flexible grid system having a plurality of individual cells interconnected together to provide flexibility and conform to the contour of a compacted subbase surface.
