Cement modified expansive soil, preparation method thereof and cement modified expansive soil ecological base material
The invention relates to the field of expansive soil slope treatment and ecological slope protection, in particular to cement modified expansive soil, a preparation method of the cement modified expansive soil and a cement modified expansive soil ecological base material. The modified expansive soil comprises the following components: 3%-10% of cement, 1%-2% of ferrous sulfate, 0.05%-0.2% of a water-retaining agent, 0.5%-2% of an organic fertilizer, 3%-10% of peat, 0.05%-0.2% of polyacrylamide and the balance of expansive soil. The water-retaining agent is used for realizing water storage and soil conservation capabilities, the organic fertilizer and the peat are used for realizing fertility, the physical and chemical properties and biological activity of soil are improved, and polyacrylamide is used for promoting the formation of a granular structure of a base material mixture, so that fertility factors such as water, fertilizer, gas and heat are coordinated, and the soil-retaining agent has certain fertility and water storage and soil conservation capabilities, can promote the growth of plants, keeps the ecological function of natural soil, and is beneficial to the vegetation growth and ecological restoration of the side slope.
本申请涉及膨胀土边坡治理及生态护坡领域，尤其涉及一种水泥改性膨胀土及其制备方法和水泥改性膨胀土生态基材，以质量分数计，所述改性膨胀土的组分包括：水泥：3％～10％、硫酸亚铁：1％～2％、保水剂：0.05～0.2％、有机肥：0.5％～2％、泥炭：3％～10％、聚丙烯酰胺：0.05％～0.2％、余量为膨胀土，以保水剂实现蓄水保土能力，以有机肥和泥炭实现肥力、改善土壤理化性质和生物活性，以聚丙烯酰胺促进基材混合物团粒结构的形成，从而协调水、肥、气、热等肥力因素，具有一定肥力和蓄水保土能力，可以促进植物的生长，保持了天然土的生态功能，有利于边坡的植被生长和生态修复。
