Solid waste-based isolation layer-planting layer reconstruction method for coal gangue ground backfilling
The invention belongs to the technical field of coal gangue ground backfilling, and particularly relates to a solid waste base isolation layer-planting layer reconstruction method for coal gangue ground backfilling. Comprising the following steps: a, uniformly paving a solid waste-based isolating layer on the top of a coal gangue layer; b, continuously and uniformly paving a solid waste-based planting layer on the solid waste-based isolating layer; the thickness of the solid waste-based isolating layer is 0.2-0.3 m, and the thickness of the solid waste-based planting layer is 0.3-0.8 m. The solid waste-based isolating layer material has a high-strength and high-density structure, so that pollution caused by rainwater leakage is prevented, plant root systems are prevented from penetrating and damaging the isolating layer, and the service life is long; coal gangue in the solid waste-based planting layer contains a large amount of trace elements and is beneficial to plant growth; the agriculture, forestry and animal husbandry wastes can be prepared into enriched and slow-released biochar which stably exists in the soil; the porous structure of the building solid waste has rich fine pores, and the stability is good. Under the condition that the isolation layer is not affected, the planting layer has a better soil structure and good water and fertilizer retention capacity, and plant growth is promoted.
本发明属于煤矸石地面回填技术领域，具体涉及用于煤矸石地面回填的固废基隔离层‑种植层重构方法。包括：a、在煤矸石层顶部均匀铺设固废基隔离层；b、在固废基隔离层上面继续均匀铺设固废基种植层；固废基隔离层的厚度为0.2～0.3m，固废基种植层的厚度为0.3～0.8m。固废基隔离层材料具有高强度和高密实结构，防止雨水渗漏而造成污染，避免植物根系穿透破坏隔离层，使用寿命长久；固废基种植层中煤矸石含有大量微量元素，有利于植物生长；农林畜牧废弃物可制成富集缓释的生物炭，稳定地在土壤中存在；建筑固废的多孔结构具有较丰富的细小孔隙，且稳定性良好。本发明在不影响隔离层的情况下，使种植层具有更好土壤结构，良好的保水保肥能力，促进植物生长。
