摘要
通过研究不同的砂粘混合比例、不同的泥炭和沸石混合用量对运动场草坪砂基坪床渗透性的调节效果厦变化规律,结果表明:1)很少的粘粒含量就会对坪床的渗透性产生很大影响,1%~3%的粘粒加入量即可将坪床的渗透性调节到正常的范围;2)单独混用10%~15%泥炭或25%~30%的沸石,同时混用15%泥炭+15%沸石或20%泥炭+20%沸石,都能够将渗透性调节到适宜的范围;3)在粘粒含量为1.5%~2%时,混合15%~20%的沸石或混合5%~15%的泥炭,也能够达到较好的调节效果。
The regulation effects of different sand-clay proportions, peat-zeoplite mixtures on permea-bility of sand based sport turf were studied. The results indicated that (1) small amount of clay affected turf permeability significantly, 1%-3 % clay could help to maintain normal permeability.; (2) Thealternatives to keep appropriate permeability were 10%-15% peat or 25%-30% zeoplite separately,or 15% peatq-15% zeoplite or 20% peat+20% zebplite. (3)When clay content was 1.5%-2%, add 15^-20% zeoplite or 5%-15% peat to achieve proper permeability.
