摘要： PROBLEM TO BE SOLVED: To provide mixed soil for forming a surface layer of clay ground having good water retentivity and water permeability. SOLUTION: The mixed soil is a mixture of fibrous conifer bark obtained by cutting conifer bark, recycled stones obtained by adding cement to construction sludge such as bentonite and hardening the same, and earth and sand. The mean fiber length of the fibrous conifer bark is preferably set to 20 mm or less. The mean particle size of the recycled stone is preferably set to 6 mm or less, and the mean particle size of earth and sand is preferably set to 5 mm or less. The proportion of the mixed soil satisfies the following relationships. The fibrous conifer bark takes up 20 to 40 mass%, the recycled stones take up 10 to 30 mass%, and the earth and soil take up the remaining portion. To form the clay ground by using the mixed soil, first a substrate layer is formed by laying and leveling recycled rubble having a mean particle size larger than that of the recycled stones, and then the surface layer is formed by laying and leveling the mixed soil on the substrate layer. Thereafter surface finishing may be performed if desired. COPYRIGHT: (C)2005,JPO&NCIPI
摘要翻译：要解决的问题：提供用于形成具有良好保水性和透水性的粘土地面的表层的混合土壤。
解决方案：混合土壤是通过切割针叶树皮获得的纤维针叶树皮混合物，通过将水泥添加到建筑污泥如膨润土中并使其硬化而获得的再生石，以及砂土。纤维针叶树皮的平均纤维长度优选设定为20mm以下。再生石的平均粒径优选设定为6mm以下，优选将砂土的平均粒径设定为5mm以下。混合土壤的比例满足以下关系。纤维针叶树皮占20〜40质量％，再生石头占10〜30质量％，土壤占据剩余部分。为了通过使用混合土来形成粘土，首先通过铺设和调平平均粒径大于再循环石块的回收瓦砾来形成基底层，然后通过铺设和调平混合土而形成表面层在衬底层上。此后，如果需要，可以进行表面精加工。版权所有（C）2005，JPO＆NCIPI
