Preparation method and construction process of improved expansive soil
The invention discloses an improved expansive soil preparation method and a construction process thereof, and the method comprises the following steps: based on the total weight of the improved expansive soil as 100%, uniformly mixing and stirring 6%-11.5% of phosphate tailings, 10%-17.5% of weathered sand, 0.1%-0.5% of basalt fibers, 15%-20% of water and 50.7%-68.7% of expansive soil to obtain the improved expansive soil. The problem that expansive soil expands when encountering water, loses water and shrinks is effectively solved, on the premise that the expansion rate is improved and the strength of the improved soil is guaranteed, the effect that industrial waste residues which are difficult to dispose are used as an additive is achieved, and the advantages of being environmentally friendly, economical and short in construction period are achieved. The improved expansive soil is used as a backfill material, the mass is light, and the stability is better than that of original expansive soil.
本发明公开了一种改良膨胀土制备方法及其施工工艺，方法包括：以改良膨胀土总重量为100％计，将6％‑11.5％的磷尾矿、10％‑17.5％的风化砂、0.1‑0.5％的玄武岩纤维、15％‑20％的水、50.7％‑68.7％的膨胀土混合搅拌均匀，得到改良膨胀土。不仅有效的解决了膨胀土遇水膨胀失水收缩的问题，而且在改善膨胀率且保证改良土强度的前提下，同时做到了将难以处置的工业废渣作为添加剂加以利用的效果，做到了环保、经济、施工工期短的优点。改良膨胀土作为回填料，其质量较轻且稳定性相较于原膨胀土更佳。
